Abstract :

We present data on the seasonal variability of small pelagic fish catches and their relation to the coastal processes responsible for them around the island of Java. This study uses long fish-catch records (up to twenty years) collected at various points around Java that were selected from the best-quality harbor records. Seven years of ocean color satellite data were also used in this study. The study selected four regions that represent the four edges of Java. Data analysis shows that the annual fish-catch pattern is determined by monsoonal activity. The monsoon greatly influences the appearance of warm and rich surface currents in the Java Sea, surface water transport and upwelling in the Sunda Strait, upwelling in the Indian Ocean, and indirect upwelling in the Bali Strait (for details on the regional oceanography, see Gordon [this issue]). These coastal processes, which differ for each region, influence fish catch and fish distribution. The natural Read more..

Author
:M. Prussi; M. Padella; M. Conton;

Abstract :

The upgrade to biomethane allows extending biogas applications to transport sectors, supporting EU goals toward carbon neutrality. Biomethane produced from biogas upgrading can today rely on a large number of plants, estimated by the European Biogas Association in over 17000 in 2016, for a total installed capacity of 9985 GW (EBA, 2017). After 2020, biogas and biomethane will count towards the 32% target of renewable energy share of the EU energy consumption, and towards a sub-target of minimum 14% of the energy consumed in the transport sector by 2030 (REDII). In this framework, the paper aims to define the current market penetration of biogas upgrading technologies. A database has been created for EU-28, to highlight the relative importance of each technology. Based on the database, a EU production potential is defined, along with the EU demand potential for transport, in order to verify the match between supply and demand. The analysis of the current state of play of the sector s Read more..

Abstract :

In the Kingdom of Saudi Arabia (KSA), millions of worshippers come from across the globe to perform religious rituals of Pilgrimage (Hajj) and Umrah. Madinah-tul-Munawara is one of the holiest city, where pilgrims come after performing rituals in Makkah. In this city, most of the collected municipal solid waste (MSW) is disposed of in the landfills after a partial recycling of paper, cardboard, and metals (~10-20% of total MSW). The Saudi’s government has recently launched a new policy of Vision 2030, which outlined the safeguard of local environment through increased efficiency of waste recycling and management, pollution prevention strategies and generating renewable energy from indigenous sources, including the waste. Currently, the recycling practices in KSA are mainly regulated by an informal sector through waste pickers or waste scavengers. Read more..

Abstract :

Solid state anaerobic digestion is a safe and environmental friendly technology to dispose solid wastes, could produce methane and reduce the volume of wastes. Three biomass residues from palm oil mill plant including empty fruit bunches (EFB), palm press fiber (PPF) and decanter cake (DC) were evaluated for methane production by solid state anaerobic digestion. Oil palm biomass was mixed with inoculum at F/I ratio of 2:1, 3:1, 4:1, 5:1 and 6:1 based on the volatile solid (VS). Results show that among the five F/I ratios tested, the F/I ratio of 2:1 gave the highest methane yield and methane production for all biomass residues. The highest cumulative methane production of 2180 mLCH4 was obtained from EFB followed by PPF (1964 mL CH4) and DC (1827 mL CH4) at F:I ratio of 2:1. The highest methane yield of 144 mL CH4/gVS was obtained from EFB followed by PPB (140 mLCH4/gVS) and DC (130 mLCH4/gVS) at F/I ratios of 2:1.

Title
:Biomethane production via anaerobic digestion and biomassgasification
Author
:Li, Hailong; Daheem Mehmood; Eva Thorin;

Abstract :

The transport sector accounts for the second biggest greenhouse gas emission in the European Union (EU). In order to achieve the target of CO2 emission reduction there is a rapid growing interest in using biomethane as fuel for transport applications. Biomethane can be produced through anaerobic digestion or biomass gasification. Anaerobic digestion is a biochemical process. Since the raw gas contains approximately 65vol% CH4 and 35vol%, an upgrading process is needed to remove CO2. Göteborg biomass gasification project (GoBiGas) is the world's first demonstration plant for large-scale production of biomethane through the gasification of forest residues. To achieve high purity CH4, a methanation process is required after gasification. This work compares these two technologies from the perspective of energy efficiency. Simulation results show that they have similar efficiencies: 62-64% for AE and ∼65% for GoBiGas. Read more..

Author
:Cantika Setya Permatasari; Johan Fahrizki; Nugroho Adi Sasongko;

Abstract :

The coal-fired power plant is the most dominant in the world where it currently fueled about 38% of global electricity. This is due to the relatively cheap price of coal and high calories produced. 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. Utilizing 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 biomass power plant and can also be a coal-fired power plant with a certain percentage mix. Many researchers conducted an analysis using the Life Cycle Assessment (LCA) method to determine the emissions produced differences between coal-fired power plants compared to the Biomass co-firing system.

Abstract :

The use of Pure Plant Oil (PPO) as a fuel blend in a power plant is mandatory as stipulated in the Ministerial Decree of Energy and Mineral Resource of the Republic of Indonesia. However, the implementation of PPO used in power generation has many obstacles due to a lack of information concerning the impacts of PPO used in the operating performance of the power generation engine. In this study, the effect of PPO as a blended fuel with High-Speed Diesel (HSD) was studied by using the gas turbine with a capacity of 18 MW. The PPO was blended based on volume with a ratio of 0%, 5%, 10%, and 20%. As the results, it is shown that the use of PPO with a blend ratio of 20% is the maximum fuel blend ratio according to the threshold value of a flue gas temperature and a vibration velocity in the gas turbine.

Abstract :

Pada akhir Maret 2017, telah dikeluarkan regulasi baru oleh pemerintah terkait harga jual listrik. Sayangnya, harga jual listrik yang baru ini lebih rendah dari pada harga jual listrik sebelumnya. Penetapan harga baru ini dianggap akan menurunkan tingkat keekonomian dari pengoperasian pembangkit listrik tenaga biogas (PLTBg), sehingga pembangunan PLTBg di Indonesia menjadi kurang menarik bagi para investor. Kondisi ini sangat tidak baik bagi iklim pembangunan energi terbarukan di Indonesia. Untuk itu berdasarkan studi kasus pembangunan PLTBg Terantam, Riau maka direkomendasikan pemanfaatan gas metana tidak hanya sebagai bahan bakar PLTBg saja tetapi juga sebagai pengganti sebagian bahan bakar cangkang di boiler PKS. Makalah ini membuktikkan kenaikan tingkat keekonomian dari hasil penjualan cangkang untuk PLTBg dengan kapasitas 1.025 kW. Estimasi ketersediaan jumlah gas metana dilakukan dengan menggunakan metodologi UNFCCC (United Nations Framework Convention on Climate Change). Deng Read more..

There have been dramatic improvements in the computer software and hardware used to simulate and model the distillation process and potential response to experimentation, but mastering the art of distillation process and control still requires solid understanding of a large body of information. With a focus on achieving product purity at low cost, Distillation Control, Optimization, and Tuning: Fundamentals and Strategies highlights core concepts. These include process variables for continuous binary distillation columns and the four basic control strategies, the distillate and bottoms product quality performance objectives, and the tuning o Read more..

Abstract :

Recently, the amount of Yogyakarta province municipal solid waste (MSW) came into Piyungan landfill site stood at around 470 ton/day consisting of 77% organic and 23% inorganic fractions. Annually, there was an increase as many as 8% per annum for the amount of MSW. Reduction of the MSW can be "forced" in integrated waste management site (in Indonesia is called TPST) which was built in the municipal level. In each TPST, there are two main activities which are Recycling and Composting. Both scenarios assume that 23% of inorganic waste can be recycled so that the subsequent need is to manage organic waste. Based on these considerations, calculations performed with: 1). Scenario 1: The TPST has been operated but there is no waste reduction at the source; 2). Scenario 2: TPST is operated and followed by solid waste reduction at the source. If the second scenario is applied, the amount of waste that goes to landfill Piyungan can be reduced up to 200 ton/day. Actually, scenario 1 is the r Read more..
