Abstract

Increasing world oil prices have a huge impact on national energy needs. Indonesia's economic growth requires the development of alternative energy sources based on 10 basin assessments in Indonesia, coal methane gas potential is estimated to reach 337 TCF of gas in place (Advanced Resources International, inc). The research location is located in the Basin of Asam-Asam,South Kalimantan. Targeted research on the Miocene Warukin Formation. The data used to evaluate Coal Methane Gas potential include surface geology data and coal sample analysis, as well as characteristics of regional anomaly bouger for South Kalimantan. The development of cleats and fractures in coal at the observation site can be classified into high-intensity vitamite-rich coal categories. Coal Warukin Formation has an average Rv value = 0.56% with standard deviation 0.02%. and is ranked in sub-bituminous coal rank. While for other Warukin Formation coal has an average Rv value = 0.58% and entered in rank (bit) bituminous coal with type of methane gas is the type of bio & thermogenic gas mixture. When viewed from the thick layer of coal and gas type, the Warukin Formation coal in the location of research is quite interesting when included in the coal resources of economical coal methane gas.

Abstract

Kelurahan Tegal Alur, Kecamatan Kali Deres, Jakarta Barat, khususnya di RW11, memiliki masalah dengan kebutuhan air bersih. Air sumur yang ada menunjukan sifat fisik agak keruh, berwarna kuning apabila mengenai baju atau dinding, bersifat sadah atau kurang dapat melarutkan sabun, serta menyebabkan rasa tidak nyaman di kulit atau lengket. Di sisi lain, air bersih yang disediakan oleh Perusahaan Daerah Air Minum (PDAM) memiliki debit yang kecil, terkadang juga berwarna keruh dan hanya tersedia pada malam hari, sehingga banyak penduduk yang selanjutnya membeli air untuk keperluan hidupnya. Sejumlah data mengenai permasalahan air bersih diambil dengan mengunjungi lokasi mengenai ketersediaan air bersih dan juga sampel air bersih.  Dari hasil observasi disimpulkan bahwa diperlukan alternatif lain untuk memperoleh air bersih selain dari kedua sumber yang sudah ada. Penggunaan alat filtrasi air yang dapat mengurangi kadar pengotor yang tidak sesuai dengan kualitas air bersih merupakan salah satu jalan keluar dari permasalahan tersebut. Selanjutnya, penyuluhan mengenai pembuatan seperangkat alat filtrasi air bersih sederhana diberikan kepada masyarakat dengan harapan masyarakat dapat membuatnya secara mandiri. Jumlah peserta yang mencapai 46 orang dan banyaknya pertanyaan yang diajukan menunjukkan tingkat tercapainya tujuan dari penyuluhan ini.
