Abstract

Acid mine drainage (AMD is a term generally used to describe infiltration of acid surface water in the mining areas. The study of the processs for formation acidmine drainage can be approached by two methods, the static and kinetic test. In the static test, that formed acidare determined by total sulphur content with an assumption that all sulphur contented in the stones are oxidized. While in the kinetic test, the acid are determined from is reaction stoichiometrically by using total both ion Fe2+ and H+, solved in the water as data in calculation. Kinetis test methods can be applicated with leached column test. Kinetic analysis of the test results on 5 samples of coal mine waste rock, it can be said that each of the rock samples as potentially acid forming rock it can be stated from the results of the analysis on pH value, content of Fe metal, ion sulfate and TSS of leachate obtained.

Abstract

This service activity provides benefits to CV Pandawa Farm, because it uses cow dung into environmentally friendly fuel energy. Sarnubi CV Pandawa Farm's Cattle Farm is a cattle farm that has been established for more than 10 years. more than 30 individuals. The location of this farm is in the Sukawinatan area which is not far from the Palembang City Waste Landfill. The environmental conditions of this farm are not good because health management of cow dung has not been implemented here. Processing cow dung into biogas can have a good impact on the environment because it maintains environmental cleanliness. Apart from that, biogas can be used to replace fossil fuels. CV Pandawa Farm does not yet understand how to process cow dung into biogas. In this socialization, counseling was provided by providing knowledge and understanding of how to process cow dung waste combined with tofu industry waste into biogas using a Fixed Dome Digester

Abstract

Hidrogen merupakan gas ramah lingkungan yang dapat dihasilkan melalui proses elektrolisis air untuk memisahkan hidrogen (Hâ‚‚) dan oksigen. Pada penelitian ini digunakan elektroliser sel kering dengan membran polyvinyl alcohol (PVA) sebagai pemisah antara dua elektroda baja tahan karat 316 guna memperoleh komposisi hidrogen yang lebih tinggi. Penerapan membran PVA terbukti mampu meningkatkan produksi hidrogen secara signifikan dibandingkan tanpa penggunaan membran. Selain itu, pemanfaatan elektrolit KOH dalam proses elektrolisis mampu meningkatkan arus listrik, yang secara linier berbanding lurus dengan kenaikan kebutuhan daya listrik serta menghasilkan produksi gas hidrogen yang lebih besar. Gas hidrogen yang dihasilkan kemudian dikonversi menjadi energi listrik menggunakan sel bahan bakar hidrogen untuk menyuplai stasiun pengisian daya dan telepon sebagai beban, dengan status pengisian dikategorikan berhasil (CS) atau gagal.

Abstract

Indonesia is a country with the largest energy consumption in southeast asia and fifth in asia pacific in primary energy consumption, after a chinese, india, japan, and south korea. If considered sectorally, so having the greatest share of the transportation sector, is as much as 42%, higher than the industrial sector with of 36. Hence the need of the use of environmentally friendly alternative energy and new and renewable energy ( ebt bioetanol ) as. Bioetanol can come from organic waste as klutuk stems of a banana tree. To research it will study and to making delignifikasi adsorbsi klutuk bioetanol of a banana stem. To research will be done study delignifikasi and adsorbsi to making bioetanol of a banana stem klutuk. First, perform the process pratreatmen and delignifikasi in a banana stem klutuk with variations konsetrasi naoh 10%, 20%, 30% and temperature warming namely 100oC, 125oC, 150oC, 175oC, and 100oC. At the delignifikasi this can be said that on the concentration naoh 10% in 150oC, warming temperatures produce levels of cellulose and lignin best, to the cellulose and lignin 81,3% levels 10,1%. A banana stem fiber that has been in delignifikasi, next will be done and also hydrolysis fermentation to produce bioetanol. Bioetanol produced the application will be done distillation to separate bioetanol and water. Bioetanol next analysis used a gcms and obtained bioetanol 80,34%.
