Besides that, several industries such as the cement, paper, textile, and fertilizer also use coal as fuel for production process. Due to that the coal waste such as ash was generating as increasing coal usage. Therefore, further research was carried out to investigate ash content and chemical composition of coal with various types of calories in the South Kalimantan and Central Kalimantan. In addition, this study provides information about management and potential processing of coal ash so that environmental pollution able to minimized. The method used to obtain primary data to determine the content of each parameter is by direct testing on each parameter for variations in the type of coal calorie. As a result, coal with low to high value has a percentage of ash content, respectively 2.5%; 2.3% and 9.7% and mineral content, respectively 77.40%; 0,96% and 95.06%. As well as the chemical com...

In real practice is still not clearly defined for the effectiveness of salinity gradient power (SGP)-RED due to the limitation of artificial saline water. Generally, South Kalimantan Indonesia is rich by wetland and coastal area. Due to that wetland saline water is potential as saline water sources for collection the SGP. This experiment aims to investigate the impact of natural feed stream wetland saline water was collected from Muara Halayung South Kalimantan-Indonesia to demineralized (WSW),artificial brackish (ABW) (0.35 wt %NaCl), and artificial seawater (ASW) (3.5 wt % NaCl) in terms of power density measured on a lab-scale RED membrane stack prototype 12 x 12 cm. Ion exchange membrane (IEM) was used in this work consisted from cellulose modified Anion Exchange Membrane (AEM) by EDTA-quaternization (EDC) process. Whereas, Cation Exch...

Minyak jelantah merupakan hasil dari sisa penggorengan rumah tangga yang setelah penggunaanya menjadi limbah dan dapat mencemari lingkungan. Penelitian ini bertujuan untuk memproduksi biodiesel dengan memanfaatkan campuran antara minyak kelapa dan minyak jelantah terhadap efek penambahan metanol dan waktu reaksi optimum dari pembuatan biodiesel. Proses produksi biodiesel dari campuran kedua bahan baku menggunakan proses dimana minyak kelapa dan minyak jelantah dicampurkan berdasarkan %-v/v dari 200 mL dengan perbandingan minyak jelantah (MJ) dan minyak kelapa (MK) yaitu 100MJ:0MK; 75MJ:25MK; 50MJ:50MK; 25MJ:75MK; dan 0MJ:100MK dengan komposisi metanol serta esterifikasi 38%; 30%; 28%; 19% serta untuk trasesterifikasi 19%; 20%; 21%; 25%. Pada reaksi esterifikasi menggunakan komposisi katalis H2SO4 0,5%, dan transesterifikasi menggunakan katalis KOH 0,9%. Yield yang dihasilkan dari penelitian ...
