Abstract

The Photovoltaic (PV) industry is one of the renewable energy segments, and electricity generation from photovoltaics (solar cells) is considered one of the key technologies of the century in the future. Photovoltaic solar electricity presents an elegant way to generate electricity, because there are no movements that damage the environment, namely: zero emissions, and no noise. This study aims to determine the efficiency analysis of making Crystaline Silicon by using type dry machines. The method that is carried out is the manufacture of Crystanesilicon by using type Dry machines. Produce nano wire devices that provide efficiency above 5%, with short photocurrent circuits higher than planar control samples. Thickness The thickness of the Si wafer depends on its diameter for reasons of mechanical stability during production and further processing, and about 279 μm (for wafers in diameter 2 inches), 379.5 μm (3 inches), 524.5 μm (4 inches), 674.5 μm (6 inches) and 724.5 μm (8 inches).

Abstract

Abstract. Leachate is a liquid that infiltrates through rubbish heaps due to direct rain fall, drainage water, or water from the surrounding area and has extracted dissolved or suspended material. Leachate contains pollutants with very high concentration so that it is potential to pollute the environment. Waste treatment installation system is one solution. Waste treatment in this service uses a pool system. The problem is the limited understanding of the community/construction workers around the landfill regarding the method of making a good and correct waste treatment plant (IPL). The application of science and technology in this service is carried out with a model of assistance/ guidance on how to make a good box system of IPL so that hazardous waste from the landfill can be minimized as much as possible. The results show that assistance/guidance on how to make IPL at the landfill site adds insight into the community/construction workers around the landfill in making the IPL. They have better understood and explored the process of making a good IPL so that it can function properly in tackling pollution of the soil, water, and the surrounding environment. The process of meeting the quality standards has been recorded properly so that the construction implementation process can run more smoothly. With the assistance/guidance given, they are able to be independent individually and in groups to develop their careers in the future as construction workers, especially in making IPL. Leachate treatment units applied are anaerobic ponds, facultative pools, maturation ponds and constructed wetlands.           Abstrak. Lindi merupakan cairan yang menginfiltrasi melalui tumpukan sampah akibat air hujan secara langsung, air drainase, atau air dari area sekitar dan telah mengekstraksi material terlarut maupun tersuspensi. Lindi mengandung polutan dengan konsentrasi sangat tinggi sehingga sangat potensial untuk mencemari lingkungan. Sistem instalasi pengolahan limbah merupakan salah satu solusi. Pengolahan limbah dalam pengabdian ini menggunakan system kolam. Permasalahannya adalah terbatasnya pemahaman masyarakat/para pekerja bangunan di sekitar TPA tentang metode pembuatan instalasi pengolahan limbah (IPL) yang baik dan benar. Penerapan iptek dalam pengabdian ini dilaksanakan dengan model pendampingan/bimbingan tentang cara pembuatan IPL sistem kotak yang baik sehingga limbah berbahaya hasil TPA bisa diminimalisir semaksimal mungkin. Hasil menunjukkan bahwa pendampingan/ bimbingan tentang cara pembuatan IPL di lokasi TPA menambah wawasan masyarakat/ pekerja bangunan sekitar TPA dalam membuat IPL. Mereka telah lebih memahami  dan  mendalami  proses  pembuatan   IPL   yang   baik   sehingga   dapat  berfungsi sebagaimana mestinya dalam menanggulangi pencemaran tanah, air dan lingkungan sekitar. Proses pemenuhan baku mutu sudah terekam dengan baik sehingga proses pelaksanaan konstruksi bisa berjalan lebih mulus. Dengan pendampingan/bimbingan yang diberikan, mereka sudah bisa mandiri secara personal maupun kelompok untuk mengembangkan karirnya ke depan sebagai pekerja bangunan/konstruksi khususnya pembuatan IPL. Unit-unit pengolahan limbah/lindi TPA yang diterapkan adalah kolam anaerobik, kolam fakultatif, kolam maturasi dan constructed wetland.

Abstract

Teknologi pengeringan pascapanen produksi pertanian sangat penting dikembangkan untuk menjamin kualitas dan penyimpanan bahan. Pengembangan teknologi pengeringan energi matahari masih terbatas oleh kondisi alami sehingga tidak berlangsung kontinu. Karena itu pengeringan ini perlu diintegrasikan dengan unit sumber energi lainnya seperti biomassa, angin dan lain-lain. Kajian ini menganalisis secara comprehensive kedua sumber energy yang potensial dikembangkan di Kecamatan Konda Sulawesi Tenggara sebagai daerah yang memiliki lahan pertanian yang cukup luas. Dalam artikel ini disajikan tinjauan sistematik dari konsep dasar teknologi pengeringan matahari yang dikombinasikan dengan pemanas energi biomassa untuk pengeringan pasca panen. Dilakukan pula pengujian distribusi perpindahan panas dalam ruang pengeringan dengan backup biomassa serta mendiskusikan kualitas produk pengeringan yang dipengaruhi oleh temperature, kandungan air bahan (moisture) dan lapisan gabah. Pengembangan desain dan proses optimalisasi distribusi panas matahari sangat penting untuk meningkatkan kualitas produksi pertanian pasca panen.

Abstract

Palm Oil Mill Effluent (POME) contains a high organic load that can be converted into biogas through anaerobic digestion and subsequently utilized for electricity generation. However, maintaining stable digester conditions requires an integrated monitoring and control system capable of observing critical operating parameters. This study presents a conceptual design and theoretical assessment of an Internet of Things (IoT)-based monitoring and control system for a POME-based biogas power plant. The proposed architecture integrates an anaerobic digester, gas holder, biogas generator, ESP32 microcontroller, temperature, pressure, methane concentration, and gas flow meter, cloud communication through MQTT/HTTP protocols, and web- and mobile-based dashboards. A threshold-based control strategy is proposed to regulate gas pressure and digester temperature. This study did not include physical system implementation or experimental field testing. Based on the adopted design assumptions, processing 300 metric tons of fresh fruit bunches generates approximately 240 m³ of POME and 6,000 m³ of biogas. Using a methane fraction of 60%, a methane calorific value of 35.7 MJ/m³, and a fixed generator efficiency of 35%, the theoretical electrical energy output is estimated at 12,495 kWh per production cycle. The proposed design provides an integrative framework for future prototype development and experimental validation of IoT-based monitoring and control in POME biogas power plants.
