Abstract

Riau is the province that produces the largest coconut in Indonesia, in 2019 coconut production in Riau reached 417,172.00 tons / year with coconut production of that amount producing a lot of waste as well, one of which was coconut pulp waste of 56,943 tons. If left alone, coconut pulp waste can have a negative impact on the environment. The purpose of this study is the use of coconut pulp waste as biobriquettes and the potential of electrical energy generated in Riau. The method of making biobriquettes uses the Pirolysis method with different types of combustion, namely biomass combustion and direct combustion, the results of this study are experiments conducted from 500 grams of coconut pulp to produce biobriquettes in biomass combustion which is 360 grams and in direct combustion of 240 grams. Characteristic testing is carried out manually, using biomass stoves and biobriquettes as fuel. Biomass combustion is obtained calorific value of 229.16 cal / gram, thermal efficiency of 7%, electrical energy conversion of 0.26655 kWh and electrical energy produced in Riau Province in 2019 which is 173,432,957.3 kWh. Meanwhile, direct combustion obtained a calorific value of 216.6 cal / gram, thermal efficiency of 6%, electrical energy conversion of 0.2518 and electrical energy in Riau province of 109,314,879.6 cal / gram. It can be concluded that biomass combustion is better than direct combustion.

Abstract

On average, small and medium-scale wood processing industries produced at least 2 to 4 cubic meters of wood a day, this production produced 0.25 to 2 m3 of wood waste a day. In fact, this waste can be used as a renewable energy source by processing it into briquettes. This research will produce wood waste briquettes using the pyrolysis method from two types of adhesive, namely starch and synthetic rubber adhesive with a composition ratio of 3:1. Apart from that, the resulting briquettes were tested using a bomb calorimeter to obtain the calorific value, water content, ash content, and volatile matter content, and then compared with the SNI 01-6235-2000 standard. The resulting briquettes were then calculated using mathematical calculations for the potential electrical energy they could generate. From laboratory tests, the calorific value, water content, ash content, and volatile matter content of natural adhesive briquettes were obtained at 5194.44 cal/g, 11.3%, 1.36%, and 40.8%, while synthetic adhesive briquettes respectively had values of 6369.46 cal/g, 4.33%, 2.74%, and 25.54%. From these results, synthetic adhesive briquettes had better calorific value, water content, and volatile matter content compared to natural adhesive briquettes. Apart from that, synthetic adhesive briquettes also had greater energy potential with an energy potential of 7,407 kWh/kg compared to briquettes with natural adhesives which only had a value of 6,041 kWh/kg. Thus it can be concluded that synthetic adhesive briquettes are better quality compared to natural adhesive briquettes because they can generate greater energy, and meet 3 of the 4 test parameters based on SNI while natural adhesive briquettes only meet 2 of the same 4 test parameters

Abstract

Kuko Palm Oil Mill, currently not interconnected with PLN electricity, relies on diesel-fueled generators of 1100 kVA and 650 kVA to meet its electrical needs. To reduce diesel consumption, a Hybrid Power Plant (PLTH) system comprising generators, batteries, and Photovoltaic (PV) panels is proposed. Optimization studies, evaluating technical and economic feasibility, are conducted using HOMER software. Optimal PLTH configuration includes 8,727 kW PV, 500 kW generator, 1,000 kW generator, 25,708 battery units, and 1,481 kW converter. PLTH generates 14,339,116 kWh/year, fulfilling PKS electricity requirements. Economic analysis yields NPC of Rp356,000,000,000, initial investment of Rp77,400,000,000, operation and maintenance costs of Rp21,600,000,000, and LCOE of Rp3,147/kWh. IRR stands at 22%, NPV is positive at Rp124,000,000,000, with a 3.5-year capital return. These results indicate PLTH feasibility both technically and economically

Abstract

PLTMG Balai Pungut-Duri is one of the largest gas engine type power plants in Riau with a capacity of 7x16 MW. The efficiency produced by the Balai Pungut-Duri PLTMG is 38% with the standards set by PT. PLN Efficiency in this type of generator is 45-47.5%. One of the factors that causes a reduction in the value of efficiency in power plants is that energy is converted into work and some is wasted, one of which is energy from flue gas. The purpose of this study is to examine the potential for utilizing flue gas using the Organic Rankine Cycle (ORC). The method used in this study is the law of thermodynamics 1 to determine the parameter values needed to determine the efficiency and power generated using the Engineering Equation Solver software. From the results of the calculations carried out, the Balai Pungut PLTMG produces an efficiency of 38.49% and a power of 14,530 kW under excited conditions. In utilizing flue gas using an organic rankine cycle it produces an efficiency of 19.97% with a power of 4,556 kW. the combined efficiency that can be produced by PLTMG Balai Pungut-Duri is 50.56% with a total power of 19,086 kW, with an efficiency increase of 12.07%. The results of the study show that the use of flue gas energy can increase efficiency according to PLN standards.

Abstract

PT. ADEI PLANTATION INDUSTRY is a palm oil processing factory that has a plantation area of 11,047 hectares. This factory produces solid and liquid waste. solid waste is reused as boiler fuel and liquid waste is used for biogas. Combustion in the boiler produces boiler ash, 70% of which is used as organic fertilizer and the remaining 30% is simply thrown away. This research aims to utilize boiler ash waste in bio-briquettes and determine the electrical energy potential of bio-briquettes using the carbonization combustion method in boiler furnaces (boiler ash). The test results for the calorific value of bio-briquettes from the use of residual ash from combustion in boiler furnaces (boiler ash) were 2,214.99 cal/gr. From 1 kg of boiler ash, 11 pieces of bio-briquettes weighing 100 gr/piece, with a calorific value of 24,364 cal/gr, are produced. PT. ADEI PLANTATION INDUSTRY in one day produce 7,536 tons of boiler ash, which will produce 82,896 pieces of bio-briquettes with a heating value of 179,903,776 cal/gr, a total flow rate of heat energy of 792,020 Watts and electrical energy of 950,424 kWh. From the PLTU efficiency of 5.12%, the potential electrical energy produced in one month is 28,512,720 kWh with 188.4 tons of boiler ash and 2,261 tons of boiler ash in 1 year has the potential to become 346,904,760 kWh of electricity.

Abstract

SMK Muhammadiyah Kuok adalah salah satu dari empat sekolah menengah yang ada di Kecamatan Kuok Kabupaten Kampar dan sekaligus menjadi yang sekolahan yang tertinggal diantara yang lain. Lokasi sekolah ini berada pada titik strategis di komplek akademik tingkat kecamatan namun demikian ternyata minat masyarakat nyatanya sangat rendah untuk mensekolahkan anaknya di sekolah SMK Muhammadiyah Kuok yang hanya berjumlah total dua puluh siswa yang semuanya akumulasi dari kelas X sampai XII. Salah satu faktor penyebab kurangnya minat masyarakat adalah kurangnya daya saing sekolah dan pembekalan materi yang konvensional. Materi yang meningkatkan kompetensi siswa seharusnya menjadi daya tarik bagi masyarakat yang berada di sekitarnya. Sebagai sekolah yang menyediakan kelas jurusan bisnis digital maka materi tentang IoT seharusnya diberikan dan diajarkan kepada siswa agar selaras kurikulum dan seiring dengan era digital yang pesat. Oleh karena itu perguruan tinggi sewajarnya turut mendukung sekolah dalam pelaksanaan pembelajaran IoT dalam bentuk kegiatan pelatihan. Berdasarkan data kuantitatif isian kuesioner setelah kegiatan pelatihan tercatat bahwa sebagian besar responden menyatakan terjadi peningkatan pengetahuan dan sangat antusias mempelajari IoT.
