Abstract

Wood sawdust feedstock is one of commodity of furniture industrial waste in Indonesia. It could be used for biomass feedstock for syn-gas producing with gasification process. Wood sawdust could be alternative ways for replacing other biomass feedstock that hard to find for biomass gasification processing, it has good high heating value (HHV) of abouts 18.75 MJ/kg. Besides that open top downdraft gasifier is one of a kind biomass gasifier/reactor for syn-gas producing. It had better with the other gasifier for syn-gas producing; such as cross draft gasifier and updraft gasifier because for micro-grid electricity it has lower cost for designing and maintaining. Syn-gas is a synthetic gas that contains several elements of hydrocarbons, such as CO (carbon monoxide), CH4 (methane) and H2 (hydrogen). It could be useful for combining with internal combustion engine for producing micro-grid electricity. Syn-gas could be alternative fuel to replace gasolines or diesels fuel for internal combustion engine that converted to electrical generator as prime mover power. At this simulation study we get the result of mole fractions for syn-gas productivity from wood sawdust feedstock by using ASPEN Plus software is CO (1.622%), CH4 (6.722%), H2 (12.448%). At the end of the calculations we get HHV of syn-gas is 4.47 MJ/Nm3, gasification efficiency (Xcge) is 20% and amount of carbon in wood sawdust that convert to gaseous (Xc) is 0.43%. Simulation study by using ASPEN Plus software could be more useful for resulting syn-gas productivity without any problems. For academic communities, simulation study by using software could be solutions when we have no more cost for practicing in the workshop.

Abstract

In this era of rapid technological growth, especially in the transport sector, the development of electric vehicle in Indonesia has been a major focus since 2012. Government support through various regulations such as Perpres, Permenhub, and Permen ESDM, as well as changes to the taxation system for electric vehicles, create a legal foundation for the use and production of electric vehicles. As the adoption of electric vehicles in Indonesia, particularly electric motorbikes, increases, the need for reliable batteries becomes increasingly important. However, the adoption of electric vehicles is faced with several obstacles, such as the difficulty of finding Public Electric Vehicle Charging Stations (SPKLU) and Public Electric Vehicle Battery Swapping Stations (SPBKLU) and the high price of electric vehicles. The focus of this research is to understand the relationship between the number of stations and community mobility. In an effort to find a solution, this research uses Business Model Canvas (BMC) to describe and evaluate the business model of battery box sales and installation services for electric motorbikes. The BMC results show that this business focuses on electric motorbike owners in areas that do not have SPBKLU, offering a solution to extend the mileage of electric motorbikes.

Abstract

Penambangan sumber daya alam merupakan kegiatan vital untuk keberlanjutan peradaban manusia, memerlukan penerangan yang efisien baik siang maupun malam, di tambang terbuka maupun bawah tanah. Penelitian ini bertujuan melakukan studi kepustakaan tentang pencahayaan di pertambangan, merinci penelitian sebelumnya, dan mengevaluasi potensi pengembangan di masa mendatang. Fokusnya mencakup sistem penerangan dari aspek metode penambangan, sumber energi, teknologi, desain, hingga biaya. Dalam konteks transisi energi ke sumber terbarukan, penelitian menyoroti peluang pemanfaatan energi terbarukan di sekitar tambang. Indonesia, sebagai salah satu produsen batubara terkemuka, masih minim penelitian terkait sistem penerangan tambang. Oleh karena itu, penelitian ini memberikan peluang untuk mengoptimalkan penggunaan energi terbarukan dalam sistem penerangan tambang, dengan biaya minimal yang tetap memenuhi standar penerangan. Tinjauan ini diharapkan dapat menjadi landasan untuk penelitian lebih lanjut yang lebih efektif dan efisien di Indonesia, mengingat perbedaan geografis dan kondisi cuaca yang menjadi karakteristik unik di negara ini.

Abstract

Pemerintah menargetkan 700 GW pembangkit listrik EBT terpasang pada 2060. Kebutuhan energi listrik Indonesia pada tahun itu mencapai 1942 TWh. Dengan rencana pemerintah ini, nampak bahwa proyek pembangunan pembangkit listrik bersumber EBT akan marak sekali dilakukan di Indonesia. Hal ini membuat peluang usaha dan lapangan kerja yang lebih luas bagi masyarakat. Kesempatan yang baik ini hendaknya mampu dimanfaatkan secara optimal. Salah satunya melalui pendirian perusahaan penyedia jasa PMC. Fokus penelitian ini adalah merancang konsep perusahaan PMC menggunakan BMC sebagai alat bantu. Dipaparkan pula contoh estimasi biaya sehingga diharapkan dapat memberikan gambaran yang jelas kapan BEP dan keuntungan akan diperoleh. Hasil penelitian menunjukkan dengan penerapan beberapa elemen BMC secara baik, BEP mampu dicapai pada awal tahun kedua beroperasi atau bahkan lebih cepat. Maka peluang bisnis PMC menjadi cukup prospektif untuk diterapkan agar semakin banyak tenaga lokal Indonesia yang terlibat dalam bidang EBT. Upaya penelitian lanjutan yang lebih rinci patut dilakukan dengan memasukkan biaya overhead, inflasi, dan training/sertifikasi untuk personil.

Abstract

Sumber energi listrik sangat dibutuhkan untuk memenuhi target elektrifikasi yang merata di pedesaan. Pemenuhah energi listrik di pedesaan tersebut dapat menggunakan energi setempat yang tersedia misalkan energi air. Potensi energi air yang dapat dimanfaatkan dapat berasal dari sungai-sungai kecil dengan pembangkit mini dan mikro-hidro. Tantangan terbesar dalam pemanfaatan energi air pada sungai-sungai tersebut adalah bagaimana mendesain turbin air yang sesuai dengan tipe sungai low head tersebut. Karena setiap lokasi air memiliki kondisi lokasi yang berbeda, maka desain, pemilihan jenis dan ukuran turbin yang tepat menjadi lebih penting. Penelitian ini merupakan desain secara teoritis dalam optimasi perancangan profile sudu turbin serta analisis efek pusaran air pada prestasi turbin. Metode yang digunakan dalam penelitian ini adalah dengan mengembangakan model turbin menggunakan teori sayap. Selanjutnya dengan analisis numerik dihitung analisis daya hilang pada sistem akibat pusaran air. Hasil simulasi menunjutkan bahwa sudut serang optimum menghasilkan daya prediksi sebesar 976 W, serta daya hilang pada pusaran sebesar 8 W, sementara daya hilang total sebesar 59.5W atau efisiensi sistem berkurang 6% dengan efisiensi keseluruhan sebesar 74.5%.

Abstract

This study aims to explore the potential for biomass-based power plant to accelerate the development of renewable energy to replace the role of fossil energy in Merauke district, South Papua Province. The method used in this study is, first, to collect data and analyze the load on the grid system and the portion of the energy mix as well as the availability of woody biomass from forest areas by making a simulation of the development of a 2 x 12 MW Biomass Power Plant. Second, by conducting experiments to obtain woodchip conversion, as the fuel of the Biomass Power Plant, from the wood log and conversion from Biomass Power Plant capacity to the required biomass plantation area. The results provide an overview of the big potency for developing biomass-based power generation by utilizing biomass from the local industrial plantation forest and show the energy transition towards energy independence. This study can be useful for policy makers and opportunities for entrepreneurs or suppliers of wood biomass, as well. For the future, in terms of fuel efficiency, it is necessary to reduce the plantation area as a source of biomass for power plants by reducing the moisture content of the woodchip to increase the calorific value and utilizing the forest residue. Furthermore, the comparison cost study between fossil power plant and biomass power plant, as well as the strategy for preserving the plantation to ensure a steady biomass supply is conducted.

Abstract

This study evaluates the impact of an earthquake on a mini-hydropower plant (MHP) and formulates a disaster management strategy to enhance the operational resilience of MHPs against seismic events. Data was collected through interviews with relevant stakeholders, direct observations, and analysis of pertinent documents. The findings indicate that the 2018 Lombok earthquake caused severe damage to the catchment area, triggering increased sedimentation that disrupted the MHPs operation, resulting in decreased electricity production and escalated operational costs. Mitigation measures were implemented and proved effective in reducing debris-related downtime and improving electricity generation. Thes findings are expected to provide guidance for MHP operators in mitigating the negative impacts of earthquakes and similar disasters on plant operations.

Abstract

A simulation model of biomass gasification for hydrogen production has been further developed using Aspen Plus. The model developed is based on Gibbs free energy minimization using the finite equilibrium method. The objective was to study the effect of important parameters such as gasification temperature, steam to biomass ratio and shift reaction temperature on hydrogen concentration. Simulations were conducted for palm empty bunch feedstock. The simulation results show that the main gas components in the synthetic gas are H₂, CO, CO₂, CH₄. Hydrogen gas increases with increasing temperature, hydrogen concentration increases from 22 kg/hour to 64 kg/hour but CH₄ concentration decreases from 50 kg/hour to 0 kg/hour with increasing temperature from 500-800˚C under 500 kg/hour steam flow rate operation.
