Abstract

Green Petroleum Coke (GPC), produced by Pertamina RU II Dumai, is the product of refined petroleum, which still has good quality but has not been utilized to its full potential. Such as Sulfur 0.5%; FC 86.03%; Ash 0.10%; VM 13.82%; Moist 10, 52%; and the calorific value of 7500 kcal/kg. Therefore, one effort that can do is diversification, namely the use of GPC as a mixture of other fuels (fossil) to increase the selling value of GPC. This diversification is also in line with the national energy policy in PP. 79/2014 that the program aims to increase the availability of national energy sources. This study aims to determine the feasibility of using GPC as a coal mixture in Industry (Krakatau Steel) with an overview of economic aspects. Data obtained by qualitative methods consisting of interviews, observation, and documentation. Based on the research results from 2 scenarios, both scenario 1 (GPC 4%) and scenario 2 (GPC 18%), it is found that the NPV is positive, IRR is above the discount rate, and BCR> 1. Thus, the use of GPC as a coal mixture is considered feasible to run and can support national energy security. Keywords: Diversification, Feasibility, Petroleum Coke, Investment DecisionJEL: G11, G32

Abstract

Palm oil waste such as Palm Mill Effluent (POME) can endanger the environment, sincePOME stillcontains organic compounds with highCOD and BOD. To reduce COD and BOD level, POME needs tobe processed into environmentally friendly and useful products. One of the products is biogas, whichcan be used as fuel for gas engines to produce electricity. Biogas can be an alternative to diesel fuel.The results of the study indicatedthat the amount of biogas content from the new POME waste processcan be used to supply gas engines. It is necessary to optimize the design of the Human MachineInterface (HMI)ofthe biogas cleaning system such as bioscrubber, dehumidifier, and blower units,using instrumentation and control software called Virtual Instrument Engineering WorkbenchLaboratory (LabVIEW). LabVIEWis a system design platform and development environment for visualprogramming languages from National Instruments (NI), USA. Instrumentation and control systemsare designed for automation with graphic programming languages. The built-in interface helps simplifycomplex functions such as visualizing the control system in a large database and system-processingoptimization that has been designed.Kata kunci: biogas, gas engine, gas handling, labVIEW, POME (Palm Oil Mill Effluent)

Abstract

Generally, power plants have an environmental negative impact, due to emissions released from the power plant process. The Coal-fired power plant is the most dominant in the world. This is due to the relatively cheap price of coal and high calories produced. But on the other hand emissions generated by coal-fired power plants are quite large compared to other types of power plants, while all countries are working to reduce global warming, one of which is by reducing CO2 emissions. Utilization Renewable Energy is one of the solutions in efforts to reduce the use of fossil energy so that there is a decrease in CO2. Biomass is renewable energy which is currently widely used as fuel for electricity generation, Biomass fuel can be used 100% for a plant called PLTBm and can also be a coal-fired power plant with a certain percentage mix. Therefore, an analysis using the Life Cycle Assessment (LCA) method is used to determine differences in emissions produced between coal-fired power plants compared to the Biomass co-firing system. The result is a PLTU with a Biomass co-firing system produces lower emissions than a 100% coal-fired power plant.

Abstract

Indonesia is the world's largest source of nickel ore, controlling 27 percent of the global nickel market. Because of its unique physicochemical properties, such as malleability, high-temperature stability, strength, corrosion resistance, ductility, heat conductivity, and electrical conductivity, nickel is one of the most important metals in the industry. Nickel-based superalloys are commonly utilized to build hot-end components for aviation engines and gas turbines. The purpose of this study is to examine the use of Inconel 718 (IN718) for armor and its prospective development in Indonesia's military industry. The outcome demonstrates IN718's potential in the Indonesian defense industry, with the manufacturing of military aircraft gas turbines, submarines, military electric engines, and high-protection armor vehicles among its most prominent applications. Nickel may be recycled by using a nickel extraction technique like the liquid metal extraction-vacuum distillation (LME-VD), which produces no waste gas or solid and is environmentally beneficial. IN718's development is also by the government's goal of increasing the value-added of Indonesia's nickel production while minimizing environmental impact.

Abstract

Ketersediaan air bersih merupakan sebagian besar masalah utama diwilayah Kabupaten Manggarai Barat, Nusa Tenggara Timur. Padahal terdapat korelasi antara faktor kecukupan air, kesehatan dan pembangunan ekonomi. Salah satu daerah yang merepresentasikan kondisi ini adalah di Desa Labuan Bajo. Pesona wisata Pulau Flores yang terdapat di Kabupaten Manggarai Barat, dimana Labuan Bajo merupakan pintu gerbang untuk memasuki pesona wisata tersebut merupakan tempat yang sangat ingin dikunjungi oleh wisatawan. Sebagai bentuk upaya pemerintah untuk memperketat pengawasan dan penjagaan perbatasan maritim Labuan Bajo, pemerintah membentuk Pos TNI Angkatan Laut. Oleh karena itu, ketersedian air bersih sangat dibutuhkan di daerah tersebut. Selain untuk memenuhi kebutuhan masyarakat Labuan Bajo, meningkatkan sarana dan infrastruktur untuk mendatangkan para wisatawan yang banyak, juga untuk memenuhi dukungan logistik markas TNI AL. Untuk memenuhi kebutuhan air tersebut, maka ada 2 opsi yang diperkirakan dapat menyelesaikan masalah, yakni (1) pemetaan air bawah tanah di desa Labuan Bajo dan pemompaannya dengan menggunakan tenaga listrik dari hasil photo voltaic, dan (2) bilamana butir (1) nihil maka dilakukan pemompaan air dari reservoir yang tersedia pada jarak sekitar 3 km dari desa Labuan Bajo. Mengingat contour daerahnya, maka diperlukan pembuatan reservoir baru dan sistem pemompaan air dari reservoir yang telah tersedia, sehingga diperoleh tingkat ketinggian air yang memadai untuk mengalirkan air ke desa tersebut. Pemetaan air bawah tanah dilakukan dengan menggunakan metode geolistrik. Bilamana opsi 1 berhasil, maka sistem yang dibangun dapat dijadikan sebagai model pemompaan air bawah tanah, utamanya di wilayah Kabupaten Manggarai Barat yang memerlukannya. Kemudian air bersih yang didapat akan diolah melalui proses Reverse Osmosis untuk menghasilkan air siap minum.Kata Kunci : penyediaan air bersih, sel surya, energi terbarukan, daerah terpencil, pompa air

Abstract

The availability of clean water is a large part of the main problem in the area of West Manggarai Regency, East Nusa Tenggara. Eventhough there is correlation between factors of adequate water, health and economic development. One area that represents this condition is in the village of Labuan Bajo. The enchantment of the tourist island of Flores found in West Manggarai Regency, where Labuan Bajo is the gateway to entering the tourist charm is a place that tourists really want to visit. As a government effort to tighten border supervision and safeguards the Labuan Bajo maritime, the government formed the Indonesian Navy post. Therefore, the availability of clean water is needed in the area, besides to meet the needs of the Labuan Bajo community, improve facilities and infrastructure to bring in many tourists, also for fulfilling the logistical support of the Navy's headquarters. To meet water needs, there are 2 options that are expected to solve the problem, namely (1) mapping of underground water in the village of Labuan Bajo and pumping it using electric power from the voltaic photo results, and (2) when there is no item (1) then pumping water from the reservoir is available at a distance about 3 km from the village of Labuan Bajo. Considering the contour of the area, the needed to make new reservoirs and water pumping systems from the reservoir available, so that an adequate level of water is obtained for drain water to the village. Mapping of underground water is carried out with using the geoelectric method. If option 1 is successful, then the system that is built can be used as a model of pumping underground water, mainly in the area of West Manggarai Regency that needed it. Then the water obtained will be processed through the Reverse Osmosis process to produce ready to drink water.Keywords: clean water supply, photovoltaic, renewable energy, rural area, water pump

Abstract

Biomass is organic matter produced through photosynthetic techniques, each within the form of products and waste. Biomass energy sources have several benefits; amongst others, renewable power to provide sustainable energy sources. Biomass resources are all organic materials that can be renewed, including plants and trees specifically for that energy, food crops, agricultural waste, forestry waste and waste, aquatic plants, animal waste, urban waste, and other waste materials. Improvements in agriculture will lead to increased biomass yields, reduced processing charges, and stepped forward environmental best. Biomass material handling systems constitute a considerable share of investment capital and operating costs in bioenergy conversion facilities. The future improvement of biomass utilization for electricity is collectively burning biomass in current coal boilers and introducing high-efficiency blended-cycle gasification systems, mobile gasoline systems, and modular systems. The use of biomass as gas is more environmentally friendly than fossil fuels. Some types of biomass can be used as a fuel with certain characteristics, such as rice husks and sawdust which will be reviewed in this review. Biomass, as a substitute for coal used as fuel for power plants, has almost similar specifications to coal. Where the value of HHV coal is 5217 kcal/kg (adb) while rice husk, teak sawdust, and Ironwood sawdust have HHV values respectively 3380 kcal/kg (adb), 4460 kcal/kg (adb), and 4465 kcal / kg (adb). Other tests conducted are volatile content, fixed carbon, moisture, and dust content.
