Universitas Darma Persada


Abstract

Ship engine damage has become a common thing and not just any technician can diagnose any damage properly. On the other hand, people who are experts in repairing the damage are very limited in number. The computer system can replace the ability of an expert in a field to be used repeatedly in different places and where it is for the beginner technicians. One of method for implementing a computer system is the Bayes theorem model. The way Bayes theorem works is to consider the various possibilities of facts that occur in the diagnosis process based on input from an expert. The system built results in getting better if the facts of the rules needed by the diagnosis process can be inputted more fully in the future.

Fossil Fuels Dependency and Renewable Energies Tendency: An Analytical Reading to The Energy Roadmap in ASEAN Countries
Arif Gunawan Sulistiyono

Darma Persada University


Abstract

Southeast Asia region, which is located on the equator and blessed with abundant sun radiant, volcano, and tropical climate, has a huge reserve in renewable energy sources such as the wind, geothermal, solar, and estimated to contribute around 70% in the total electricity produced by 2050. However, none of the countries in the region aims an aggressive target in the usage of renewable sources in their energy development roadmap.
All of 11 countries in Association of Southeast Asia Nations (ASEAN) namely Indonesia, Thailand, Malaysia, Singapore, Philippine, Brunei Darussalam, Vietnam, Laos, Myanmar, Cambodia and Timor Leste are relying on fossil fuels. Even Indonesia as the biggest economy in the region puts only a 31% target of renewable energy mix in its energy roadmap by 2050. It is far from the ideal level set by the Global Wind Energy Council at 70%.
However up until now, there is no specific research that analyze and compare the energy roadmap among ASEAN country, in regard to the development of renewable energies, especially related to their dependency on fossil fuels. This thesis is aimed to elaborate more on why countries in the region tend to set conservative targets in their energy roadmap, and whether it is heavily related to their dependency on fossil fuels. And later, we can see the opportunity to invest in renewable energy in the region timely.

Abstract


Many fishing vessels in Indonesia are built traditionally, usually not with regulations or instructions and approval from naval architect in this case is classification of ships. Along with the development of advances in technology, ships can be made from various materials. The Ministry of Maritime Affairs and Fisheries of the Republic of Indonesia made fishing vessel using fiberglass materials and is assisted by qualified software. Therefore, the manufacture in the design can be easier. The main concern is hydrodynamic performance, seen in terms of seakeeping and safety performance in fishing vessel designs. Therefore, it needs to be studied more deeply about seakeeping and the safety of the ship. The results show that the three ships are only able to operate at a wave height of 1.5 m. Safety surveys show that the three vessels still do not meet the standards set by IMO.

Abstract

Coal is one of the most abundant energy sources in Indonesia. Coal in Indonesia is a foreign exchange-producing export and is also being used as an energy source to replace oil and natural gas. Coal demand is still high for export and domestic needs, coal production in one region of South Kalimantan Province will increase from 8,000,000 tons / year to 10,000,000 tons / year. Increasing the amount of production requires proper transportation. So, the comparison of coal transportation on land and river starts from the carrying capacity, economic value and exhaust emissions. The calculation of economic feasibility by the Payback Period method, Net Present Value, Profitability Index, and Internal Rate of Return and calculation of exhaust emissions. Land transportation used is a 30 ton capacity truck, Economic feasibility of land transportation with details of , Payback Period = 3,27 year, Net Present Value = Rp797.723.385.164, Profitability Index = 1,22, and Internal Rate of Return = 13%, and exhaust emissions 1.530.276,95 gr / year of 2,412 Trips. The water transport used is a 180 feet barge with a capacity of 1,000 tons, Economic feasibility of water transport with details of, Payback Period = 2,08 year, Net Present Value = Rp2.501.660.211.614, Profitability Index = 2,09, and Internal Rate of Return = 19%, the emissions produced by water transport are 1.013.749,40 gr / year from 814,05 Trip. Truck production is 8,466.120 tons. The amount of production cannot be increased because the capacity of the cargo has been maximal and the number of queues of vehicles is tide. Production of water transport is 8.140.500 tons / year, the production can be increased to 12.210.750 tons by increasing the load capacity from 180 feet barges to 230 feet barges. Based on the results of calculations, the best transportation for coal transportation is water transportation.

Abstract

Batam City, which is part of the Riau Islands province, is a connecting city between Indonesia and Singapore. Batam City is located in a very strategic location in the border region between countries, neighboring one of the worlds business centers, namely Singapore. For this reason, marine transportation has a very important role in maritime countries like Indonesia. The high intensity of Batam and Singapore transportation cannot be separated from the Chinese population of Batam which is a community group in the city of Batam. The existence of Batam Chinese has been going on for centuries, since they came from mainland China using boats. With tenacity, social networks and geographical proximity to Singapore, Batam Chinese people become dominant in the economy in Batam. This study seeks to show maritime aspects and shipbuilding technology and their relationship with social society through transnational concepts. With globalization, and to develop networks, people really need sea transportation to support the transnational process. For all that, maritime safety is needed which greatly affects the sustainability development efforts, especially sea transportation activities.

Fakultas Teknologi Kelautan Jurusan Teknik Sistem Perkapalan Universitas Darma Persada


Abstract

Indonesia as a maritime country and islands, boats are the only option for people to travel outside the region in order to meet daily needs. These usually ships operating from morning to evening with the average shipping time 2-3 hours each way in which ships are generally small so that the engine and the passenger seemed to be in the same room. Consequently inevitably generated noise sound machine can not be avoided and noise arising this will certainly affect the health of people if the noise exceeds the threshold value that has been set if it happens constantly in a long time. Threshold Limit Value (TLV) noise (caused by the sound of the engine, etc.) has been established by local and international standards. Under the provisions of the above then performed experiments to create a Diesel engine casing made from plywood to the outside while the inside is used Polyurethane (PU) and Styrofoam successful minimize noise due to the Diesel engine operation.

Abstract

Recent development in construction industry has come to the point where it requires a new kind of materials with higher mechanical properties such as compressive strength, tensile strength, and flexural strength. Grout materials are needed for pad bearings and structural repairs. However, grout materials that are readily available on the market only has limited strength, as well as using materials on micro scale. Therefore, it is necessary to develop grout materials using materials at nano scale, like nanosilica, which is able to increase the mechanical properties. The purpose of this study is to determine the optimum content of nanosilica in grout material. Initial mix was given code G0. Then the nanosilica was added with 1% content (code G1), 2% content (G2), 3% (G3), and finally 5% nanosilica content (G5). Compressive strength tests were carried out when the grout were aged 1, 3, 7, and 28 days. Whereas flexural strength test were carried out at 28 days old grout. From the research, it was found that the most optimal nanosilica content was at 3% (G3). The contribution of this research is to introduce nanogrout as an advanced material, to overcome the challenges of increasingly complex construction work in the future

Rolan Siregar

Department of Mechanical Engineering Universitas Darma Persada, Indonesia


Abstract

Brake failure is one of the reasons for driving accidents. A measuring instrument to indicate a brake vehicle whether it is still feasible or not to operate has not yet been implemented in Indonesia. This is because the formulation of the feasibility of a brake that has been operating for a certain time has not yet achieved maximum results. So this research is considered very useful to be developed in order to reduce the number of accidents in Indonesia. Excess heat (overheat) is a phenomenon that occurs due to damage to one element of the braking system, where this can result in total brake failure. the imbalance of the grip each brake is approximated to affect the balance of the vehicles motion when braking is done on a straight road or on a turning road. Braking loads can be calculated from the size of the normal force on each wheel in braking conditions. The initial stage in solving this problem is to define the form of loading on a brake system as a whole, to then be applied in numerical simulations of temperature distribution using FEM (Finite Element Method). Heat flux is the rate of heat energy transferred through a surface per unit time. In this study will be discussed about brake temperature which is a brake performance indicator whether it is within normal limits or not.

Abstract

The purpose of the study is to investigate the effects of various air flow rate or superficial gas velocity to obtain the optimum distribution of solid phase in the Circulating Fluidized Bed (CFB). The Computational Fluid Dynamics (CFD) method used for simulations uses the Eulerian-Eulerian approachs incorporating the Kinetic Theory of Granular to calculate the motion of particles and the standard k-e turbulence model to simulate the fluid flows. The simulations were carried out using four different air mass flow rates, based on the air consumption in the combustion of coal used in real CFB boiler. Since this simulation is the preliminary study of the particle dynamics in CFB, the combustion process had not simulated yet. In this work, the complex flow has been resolved by applying the CFDSOF commercial CFD software. The distribution of pressure, particle velocity and volume fration in the CFB were investigated to obtain the optimum results of the fluidization. The simulation results showed that at the actual air flow rate, the fluidized bed showed the bubble instead of turbulent fluidization, and increasing the velocity swifted it into the turbulent. The optimum air flow found to be between 60% - 75% of excess air value.

In this era of globalization, it is difficult for us to calculate family inheritance because there is no media that is a place to count, plus families of members who are separated and far from other family members. Media websites are the right thing because they are not limited by distance and communication. In this case, our website uses a system calculator to calculate the inheritance portion of each family member. People also forget about the way to calculate zakat from the work that is their salary. On the website that we made, we added a zakat calculation calculator feature. When people already knew about zakat and its inheritance, we added a donation feature. In this donation feature, we made a website display ahead of us for people who really needed help.

Abstract

Respect for the sea is a form of local wisdom of Indonesian people who are maritime countries. Many ethnic groups in Indonesia see the sea as something sacred apart from the profane. Traditions and rituals related to the sea are a sign of respect for the sea. Likewise in Chinese society in Indonesia, respect for the sea appears with the existence of temples located on the coast. Globalization is characterized by the loss of local wisdom and the loss of sacred traditions, but here can be seen the persistence of local wisdom traditions in viewing the sacred. This form of respect for the sea as a form of local wisdom in Chinese society in Indonesia manifested itself in the tradition of respecting the sea guardian deity in the temple. The study was conducted using ethnographic research methods, which were carried out in several temples that had sea guardian deities as host gods, such as in Makassar, Jakarta, Krawang, and Madiun. The tradition of respecting the sea protective deities in Chinese temples in Indonesia shows local wisdom in maritime society. Respect for the sea guardian deity (Mazupo) in XianMa temple, Makasar, Sian Jin Kupoh temple, Krawang, Dizangyuan temple, Jakarta and Hwie Ing Kiong temple, Madiun shows the Chinese believe in a sacred thing manifested in the deity by presenting offerings. The sacred belief in deitys respect is a form of local wisdom that persists among the Chinese.

Dr. Eko Cahyono Ir. Ahmad Rozak Ari Artadi, Ph.D

Universitas Darma Persada


Abstract

Japanese companies that invested in various ASEAN countries mainly in manufacturing sector already established global production chain. That means even if the parts were produced in different plants in various countries, however the parts have same standard and the results is high accuracy, therefore when the parts were assembled on assembly line, all the parts can suit each other, and yields the ultimately good finishing products. It does not matter where the finished products were assembled, because all the countries have same standard of production. However, in order to achieve the high accuracy products in delivery target, the companies need high skill human resources which have similar attitude and abilities.
Manufacturing means making things or add value to the material, and the most important thing in the process is to educate people who make the products. Making high quality products which affordable price and satisfied the customers is not a simple process. It needs workers who have excellence skill, spirit, zest and pride to make product perfectly well, which known as monozukuri. This is the ultimate reason why monozukuri should be taught to Indonesian students.
Based on discussions, surveys and interviews with Japanese institutions, companies and experts, actually the companies need workers with good communication abilities, understand manners, work ethics, and good team work. From the companies needs, we define that monozukuri course should have learnings elements such as Japanese language, Japanese manners, Japanese corporate culture, 5S activity, Horenso, Kaizen+3M, QCC and PDCA, Kanban+JIT, Visual Management, Factory visit and A3 report.

Abstract

The purpose of this study is to choose the best catalyst from three choices, namely hydrochloric acid (HCl), sulfuric acid (H2SO4) and phosphoric acid (H3PO4) to reduce the high free fatty acid (FFA) content of sludge palm oil (SPO) to a minimum level (<2%) for biodiesel production through the esterification process. The acid catalyst esterification process was carried out to evaluate the low content of FFA in the SPO that treated with the effect of the methanol synthesis process with the comparison of the three catalysts. The results showed that FFA SPO was reduced from 4.4% become 0.03% using HCl, become 0.1% using H2SO4 and become 1.3% using H3PO4. The FAME value of the biodiesel produced from the SPO esterification was 94.77% using HCl, 92.38% using H2SO4, 89.68% using H3PO4. With an intense research focus, ideal catalysts can be developed to optimize biodiesel production economically and environmentally for a better future.

Abstract

The purpose of this study is to determine the effect of the addition of Tetrahydrofuran (THF) as co-solvent and the alcohol used to the methyl ester produced in the transesterification reaction of biodiesel manufacture from Sludge Palm Oil. Transesterification method has been widely used in the process of making biodiesel. This reaction is a slow reaction because it takes place in a two-phase system. These problems can be solved by the addition of non-reactive co-solvents. The addition of the co-solvent aims to form a system of solutions which originally two phases into a single phase because the solubility of alcohols in the triglycerides is very low. THF is also more economical and healthier for biodiesel production because it comes from biomass and non-toxic. The results showed that transesterification with the addition of co-solvent resulted in higher methyl ester content than conventional method.

Abstract

The objective of this study is to estimate the cost of biodiesel fuel from POME with a production capacity of 72,000 CPO per year. Because until now the development of biodiesel in Indonesia is still far from the target and the high price of vegetable oil as raw material, causing the cost of biodiesel in the market is not competitive than diesel produced from fossil energy. POME waste generated from palm oil mills can be processed and converted into biodiesel. Biodiesel produced can be used as a diesel replacement fuel for palm oil mill itself even sold to the market. This concept will provide optimal benefits and benefits to replace diesel fuel consumption. In addition to technical aspects such as diesel consumption requirements and production proccess selected to support the biodiesel production process, cost benefit analysis is an important and systematic approach to biodiesel plant declared economically viable.

Abstract

Biomass from EFB is considered as potential renewable energy sources to be developed in Indonesia. EFB can be efficiently converted into valuable and useful fuel products through gasification. Gasification is a process of biomass conversion into syngas. Syngas is a raw material for most other chemical products, such as Methanol, Ammonia, and DME. One of type biomass that has big potential to be utilized is palm EFB waste. Research about Methanol synthesis from various biomass has been done, though little research about Methanol production based on EFB gasification. The purpose of this research is to simulate Methanol plant model based on gasification of palm empty fruit bunch by assuming that the gasification reaction and Methanol synthesis reaction are under equilibrium condition.

Abstract

Biomass from EFB is considered as potential renewable energy sources to be developed in Indonesia. EFB can be efficiently converted into valuable and useful fuel products through gasification. Gasification is a process of biomass conversion into syngas. Syngas is a raw material for most other chemical products, such as Methanol, Ammonia, and DME. One of the biomasses that has big potential and available abundantly is palm EFB waste. Research about DME synthesis from various biomass has been done. Although little research about DME production based on EFB gasification was carried out, there is no research yet being conducted on techno-economic analysis of DME Plant construction based on EFB gasification. The aim of this research is to find feasibility of small scale DME plant model based on gasification of palm EFB with 6.16 tons per h EFB feed to plant. Method encompasses step to perform simulation of the model and DME plant design, to do equipment sizing, to conduct costing, to calculate investment cost estimation, to calculate operating cost estimation, and calculation to estimate profitability in term of BEP, and calculation of economic feasibility parameters. The model predicts yield of DME product in agreement with published real DME plant operation. The result shows flow rate of DME produced is 50% of EFB feed flowrate and 73% energy efficiency obtained for pre-treated EFB. Electric power requirement has been investigated at 3683 kW and can be fulfilled by DME Plant through waste heat steam generation cycle and internal combustion engine fuelled by off-gas. Economic analysis calculated that the total investment to build DME plant in this study was USD 104,291,799. NPV calculated was USD -42,393,967, IRR at 4.2%, and PBP 18 years. Based on NPV, IRR, PBP calculated, DME plant construction based on gasification of EFB is not feasible. Feasibility can be attained, if discount rate lower than 4.4% applied. It was estimated that 4 times increase in capacity makes DME construction process feasible. This study further will be used as the base for the bigger scale techno-economic analysis of DME Plant construction based on gasification of EFB.

Abstract

Indonesias marine energy potential is estimated to reach 48 GW, but only a small portion has been realized. The world potential for tidal energy is estimated to reach 500 to 1000 TWh. Indonesias experience in wave- current energy was conducted by Erwandi et al, in 2010 where they designed ad consrutcted a current-wave power generations producing 2 to 10 kW electricity and tested in Larantuka Strait, Flores Island. In 2005 a group of ITB students had started to design and construct a 5000 We capacity ocean current and tested at Nusa Penida, Bali. Later they constructed a one 10 kW unit which has been installed at Madura strait to provide 1000 lighting of the Suramadu bridge, Surabayam(T-files, 2013).
.Indonesia is also potential place for Ocean Thermal Energy Conversion (OTEC) and other marine energy because of the difference in temperature of sea surface and the deep sea water temperature is always constant at around 24 degree Celsius which is adequate to operate an open cycle OTEC. Beginning in 1970 the Tokyo Electric Power Company successfully built and deployed a 100 kW closed-cycle OTEC plant on the island of Nauru.The plant became operational on 14 October 1981, producing about 120 kW of electricity; 90 kW was used to power the plant and the remaining electricity was used to power a school and other places.A 1 MW OTEC project was built in South India for clean water production with capacity of 7000 gallons/day by NIOT in cooperation with Prof. Ikegami from Saga university Japan in 1997. An OTEC project was built in Hawaii where it could produce 103 kW between 1993 to 1998. Another successful OTEC project is the one located at Kameshima, Okinawa Island of Japan built in 2013 where 100 kW of electricity could be produced.. Now a 10 MW OTEC is under construction in Hainan Island, Southern China. In Indonesia recently a Tidal Bridge BV announced it has begun the feasibility study for the 18 to 23-MW Palmerah Tidal Bridge project located at Larantuka Strait. It will be constructed at the end of 2108.

Abstract

Biomass derived from agricultural waste, plantation, and forestry industry in Indonesia is a bioenergy raw material that is abundant and has not been used as a source of energy raw materials. This article aims to present the performance of the four types of agricultural waste which are coconut shells, rice husks, empty fruit bunches, and sawdust used for a small scale downdraft gasification system.

The initial treatment given to the four types of waste is drying under direct sunlight for two days to achieve a water content of <10% wt. Furthermore, the energy conversion process is done on a small scale gasification system as an initial step to build a biomass-based power generation system that can be used in agricultural areas.

The characteristics of agricultural waste measured are amount of raw materials, the rate of combustion, the amount and the chemical content of tar and biochar, as well as the ability of these biomass gasification system to generate electricity through a small gas engine. Based on the results of the initial experiments showed that the downdraft gasifier was able to convert these raw materials into combustible gas with production rate and quality that will be tested in the next stage.

Abstract

The rain could be occured at the harvesting season. Hence, drying process could be delayed. This will cause the ingredients mold or germinate. So it could not be consumed or sold. Currently the quality of dried foodstuff whether for export or domestic consumption are still in a low quality. The raw material of dried foodstuff processed by drying on the open area, for example above the road surface, the home yard and the roof top. It cause the quality of dried foodstuff less hygienic. So it tends to have some problems, for example contaminate with dirt and microorganisms, eaten by chickens, birds, mice etc. Because of the agricultural products for export require consistent quality, and continuous supply, So the process of foodstuff drying should be replaced with a drying method that is not affected by the weather. To overcome this problem, a portable conveyor of solar-energized drying system (CSDS) was designed. With the portable CSDS, the dryer will be easily moved and flexible to use. However, such system has not been widely used for the drying process in Indonesia. It is because the limited research of the dryer type. The advantage of portable CSDS is that the drying process could be done continuously with a little human power. Therefore, this portable CSDS is designed to use renewable energy sources. To examine the portable CSDS, the vermicelli noodles was used for a testing of ingredients. The portable CSDS testing show that the amount of water content in the ingredients reduced, the drying rate accelerate. In addition, the amount of heat energy needed for the drying process also reduced. So the process of drying foodstuff more efficienct.

Abstract

The use of water as a cooling medium in machines in industry is common, especially industries that use smelting processes, such as metal smelting industry, flat glass industry . This paper specifically writes the potential for electricity generation in the circulation of industrial glass sheet cooling water with a flow of 1400M3 / hour
The water that has been used for temperature is from 36 degrees C to 30 degrees C by the Cooling Tower, accommodated in a 900 M3 water pond and then with a 1500M3 / hour pump, the water is raised above the Water Tank at a height of 38 meter . Water from a tank with a gravitational force is used as a cooling input into the heat exchange of the production machines through the divider header pipe. The cooling water coming out of each machines heat exchange within range temperatures of 36 - 40 degrees C is accommodated in the funnel, then with the gravitational force flowed to the Cooling Tower to lower its temperature. The cycle continues for 24 hours, 365 days, 15 years continuously and is only interrupted for a while if the electricity supply is stopped which causes the pump to stop operating
The water collected by several funnels, flowed through the header pipe with a size of 30 inches, then flowed into 4 Cooling Towers through eight distribution pipes with a size 10 inches each from two sub header pipes with a size of 22 inch each. 4M height difference between the funnel with the distribution pipe that goes into the Cooling Tower basin and the total flow volume of 1400M3 / hour or 233M3 / hour (0.0647M3 / sec) per distribution pipe, has the potential to be used as a pico hydro power plant. From the equation of the electrical energy produced by the hydro generator P = &#961; x Q x g x H x &#951; / 1000 (kW). Assuming the effective height difference is H = 4M, gravity g = 9.8 m / sec2, the density of water &#961; = 1000kg / m3, the efficiency of the turbine and generator &#951; = 0.8, there will be a total electrical energy of eight distribution pipes of 16kW. The results can be used to supply electricity for lighting, panel room air conditioning and outside lighting around the Cooling Tower

Abstract

Energy as basic comodity in human daily life has been main concern for its optimalization usage due to limited resource, so is the case with energy in industry. Plant manufacturing as business entity intended to generate continuous profit which required competitive price, quality match with customer demand, and cost efficiency, including optimalized energy consumption saving.

In a typical process of automobile production the consumption of energy can be classified into variable energy (which is relatively moderate, varies in proportion to the number of vehicles produced) and fixed energy (which is approximately 50-80% of the energy consumed during production that consumed even when no vehicles are being produced).

Most recent research not yet focus to the opportunity to convert the fixed energy to become variable energy that will lead to realize real minimum resource needed to produce product. This paper will describe method to optimalizing energy saving per unit product, by modelling arrangement of fixed and variabel energy in supply side (utility/equipment operation) & demand side (production & non production process).
