Limestone mining activities and processing industries are very potential, starting from the marble stone industry, quicklime industry (CaO) to calcium oxide industry (Ca(OH)2). One product of limestone processing is calcium lime (CaO), the result of the calcination process of limestone, on burning limestone that requires large heat. The combustion activities in the majority of the limestone industrial using traditional technology use upright stoves with an open burning combustion system. The fuel used is textile industry waste, shoe industry plus wood waste. The pilot activity of the application of upright furnace limestone combustion technology is a periodically upright combustion system with fuels that have high calorific value, coal and wood. The purpose of mixing this fuel is to use available wood and coal having high calories. This activity also provides education about limestone combustion systems using coal and wood. The application of limestone combustion technology using mixed fuels of coal and wood produces quality limestone with dry conditions with an average combustion temperature of 93.75 oC and compared to using wood fuels and industrial waste produces limestone in dry moist conditions 86.33 oC. 2019-06-01T00:00:00Z http://hdl.handle.net/123456789/29969 Good Mining Practice As The Support Of Management Of Environmentally And Sustainable Mining Usman, Dudi Nasrudin; Widayati, Sri; Sriyanti, Sriyanti; Pulungan, Linda Garut Regency is a district that has enough of the potential mineral resources, such metallic minerals and nonmetals including sand and andesite, one of the areas is Mount Guntur. Many factors encourage to stop mining activity, one of them is environmental factors. Therefore, it needs a relocation to other areas, by consideration of the potential mineral deposits, to fulfill the increasing market demand. The relocation is done as a step that mining activities do not interfere with mountain tourism, natural environmental conditions, and policies related to the environment, safety and occupational health and spatial planning. The field observations result, study geological location dominated by Qhg, Qypu, and QYM. The other geological aspects that must be considered is the distribution pattern of the river. The vegetation conditions results show that the types of vegetation found in many locations namely crops and plantations, shrubs and bamboo. Based on the calculation of immeasurable resources, there is Boulder andesite-basalt amounted to 13,515,740 MT, with an estimated average thickness taken from the surface to the deepest point of 60 meters penetration geolistrik, although in fact the thickness of andesite - basalt is absence of definite size, thereby the concretion Factor has a value of 30%. 2017-01-01T00:00:00Z http://hdl.handle.net/123456789/29968 Pengaruh Konsentrasi Larutan H2SO4 terhadap MgO, Kecepatan Pengadukan, dan Lama Pelarutan H2SO4 pada Pembuatan pupuk Kiserit dari Serpentin Asal gunung Badak Jampang Kulon Sukabumi Komarudin, AS; Sulasmoro, Bambang; Pulungan, Linda; Manan, Hilyati The role of industrial minerals in urban and rural development is significant enough, such as agriculture areas which need zeolite and calotte etc. One of the industrial minerals which can be use dasfertilizerfor agriculture usage is kieseritefertilizer which is made from serpentiniterock. Serpentiniterock contents MgO which is potential for making kieseritefertilizer. Some variables of this research are grain sizes, heating temperature and time, and H&O4 concentration. This research pointed out the effects of H2SO4 concentration on MgOd Hlution. The findings of this research were the optimum grain size of 140 mesh, heating temperature of 600 C for 1 hour 45 minutes, and H2SO4 concentration of 5M. 2005-01-01T00:00:00Z http://hdl.handle.net/123456789/29967 MENGGALI KEKUATAN INTERNAL MASYARAKAT MELALUI ENERGI BARU TERBARUKAN KHUSUSNYA LIMBAH TERNAK SAPI DI DESA WANAJAYA, KECAMATAN WANARAJA, KABUPATEN GARUT – PROVINSI JAWA BARAT Sriyanti, Sriyanti; Widayati, Sri; Pulungan, Linda; Usman, Dudi Nasrudin Energi baru terbarukan merupakan suatu pengembangan teknologi dalam rangka pemanfaatan sumberdaya alam ataupun non-alami yang dimanfaatkan untuk menjadi suatu energy baru seperti biogas dan listrik. Tenaga listrik merupakan sumber energi yang sangat penting bagi kehidupan manusia baik untuk kegiatan industri,kegiatan komersial maupun kehidupan sehari-hari masyarakat. Termasuk untuk Desa Wanajaya, sebagai desa yang merupakan penghasil ternak khususnya sapi. Desa ini merupakan pilot project dalam pengembangan biomassa menjadi bio gas, namun karena adanya beberapa kendala maka pilot project tersebut tidak berkelanjutan. Pengolahan kotoran ternak menjadi biogas selain menghasilkan gas metan untuk memasak juga mengurangi pencemaran lingkungan, menghasilkan pupuk organik padat dan pupuk organik cair dan yang lebih penting lagi adalah mengurangi ketergantungan terhadap pemakaian bahan bakar minyak bumi yang tidak bisa diperbaharui. Tujuan kegiatan PKM ini yaitu melakukan tahapan awal di dalam rencana penerapan teknologi tepat guna pemanfaatan kotoran sapi sebagai sumber energi gas dan energi listrik alternatif di Desa Wanajaya, Kec. Wanaraja – Kabupaten Garut. Besarnya produksi kotoran sapi per hari atau per tahunnya menjadi daya tarik dan kekuatan untuk bisa memanfaatkan limbah ternak menjadi biogas dan energi alternatif bagi lingkungan masyarakat local. Selain ketersedian kotoran sapi sebagai modal utama untuk pemanfaatan limbah ternak (kotoran sapi) ada factor-faktor lain yang harus diperhatikan, antara lain ; pakan ternak yang digunakan, pengelolaan limbah ternak, jumlah sapi, jarak lokasi timbunan kotoran dengan rumah dan lain-lain. Mengembangkan dan Meningkatkan kemampuan sumberdaya masyarakat didalam pemanfaatan limbah ternak menajdi berbagai alternatif baik sisi energi, biogas dan lainnya 2016-01-01T00:00:00Z
