Abstract

Indonesia merupakan negara yang memiliki banyak potensi energi berkelanjutan yang harus terus dimanfaatkan, salah satunya adalah air sebagai energi penghasil listrik. kekuragan energi listrik khusunya daerah terpencil berdampak pada penyediaan energi nasional. Energi terbarukan yang berpotensi untuk dikembangkan adalah pembangkit listrik tenaga mikro hidro (PLTMH). Dalam penelitian ini aplikasi PLTMH dilakukan di lokasi sungai lawang desa simbang jaya kecamatan bahorok. Tujuan penelitian ini adalah untuk mengetahui daya listrik yang dihasilkan PLTMH di sungai lawang. Metode penelitian yang dilakukan adalah studi lapangan, pembuatan PLTMH, pengujian dan aplikasi langsung PLTMH ke lokasi sungai lawang. Hasil penelitian aplikasi PLTMH secara langsung di sungai lawang desa simbang jaya menunjukkan bahwa daya listrik terbesar yang dihasilkan oleh generator yaitu  1100,8 Watt dengan tegangan yang diperoleh sebesar 200 Volt sedangkan untuk kuat arus yang dihasilkan adalah 5,5 Amper . Memperhatikan dari data-data hasil keluaran PLTMH yang telah diperoleh di sungai lawang, dapat disimpulkan bahwa energi dalam bentuk daya listrik tersebut dapat digunakan masyarakat sekitar sungai lawang dalam memenuhi kebutuhan listrik sehari hari.Kata kunci: PLTMH, sungai lawang , energi listrik, daya, turbin, generator

Abstract

In the process of separating leaves with sticks, the community in the Timbang Lawan Village area still uses human power and is done manually with a knife or machete. The solution is to make a stick shaver machine using a mechanical system with a capacity that is tailored to the needs of the user. The aim is to help increase the yield of palm oil sticks. The implementation method begins with examining the lack of technology and equipment in palm oil palm stick extraction, with stages 1). Follow-up surveys to partner locations to find out the work process of slashing and the output capacity to be achieved to meet market demand; 2). The design of the palm oil stick shaving machine uses mechanical energy; 3) Manufacture of palm oil stick crusher machine. 4) Test and install palm oil stick scraper machine before giving it to partners. 5) Socialization on how to maintain the shaver machine in Timbang Lawan Village. 6) handover of the shaver machine unit to the community group in Timbang Lawan Village. The results obtained where the shaved stick machine that has been completed is then handed over to the PKM partner. The machine can be operated and used by partners, where the production of palm oil sticks obtained increases by more than 100% or has a capacity of 15 kg/hour sticks, compared to manual which only gets 2 to 5 kg/3 hours of clean sticks

Abstract

The need for energy is now increasing in line with the development of human and economic growth. If you only rely on fossil energy, the needs in the next few years will greatly impact the balance of natural resources. Along with the development of the times and followed by the depletion of fossil resource reserves which have been energy throughout the world, it has given birth to many technologies for converting renewable natural resources as an effort to emphasize the use of fossil fuels. One such technology is a fluidized bed combustor (FBC). This study explains the use of waste fuel which can be used as fluidization combustion chamber planning. In designing the number of holes and the diameter of the holes, the distributor type of perforated plate is very good at distributing air flow to the sand bed for the fluidization process. The difference due to the height of the sand can be seen in the sand height of 3 cm, it takes 16 minutes to carry out the preheating process, 4 cm the height of the sand takes 18 minutes to preheating and the sand height of 5 cm takes 21 minutes to carry out the preheating process. So it can be seen, the higher the sand, the longer the preheating process but the heat storage process on the bed is better.

Abstract

Innovations related to fluidization systems using fluidized bed reactor are still needed to be developed in order to improve the fluidization process services for particle in order to produce the right fluid pressure in certain fluidized bed spaces that are currently operating. In this research, the pressurized fluid in question is air sourced from a compressor which has been arranged in such a way. The aim of the research is to obtain information regarding the characteristics of bubble resulting from the air pressure process pressing fluidized system particle. The research method was carried out by experimenting with testing fluidized bed reactor as test model in the form 8 hole, providing air pressure from compressor then observing the characteristics visually. The results of this visually documented research have been carried out and obtained. By using the number of hole 8 with height silica sand inserted to height of 25 cm, which is measured from the beginning of the hole plate before pressure is applied. After being given high pressure the bed increased to 27.6 cm, the highest bubble diameter was obtained at the input air pressure of 8 bar, which was 3.9 cm, with bed silica sand produced 26.1 cm, where the babble condition began to appear after the 9th second. Other characteristics also obtained reactor temperature of 25.45 °C where this condition is the smallest when compared to other pressure input results, this is because the small input pressure causes the temperature to be low, while the large pressure input temperature becomes higher due to many factor, including friction between silica sand, silica sand collisions, and faster movement of particle material.
