Abstract. Problems of environmental damage such as flood, garbage and drought in Indonesia is a problem that can not be solved. One of the things that cause problems to this flood is this is the decreasing of water absorption area and unconscious society not to throw garbage carelessly. Limited land in residential areas results in space for water catchment areas and few dumps. The purpose of this community service activity is to provide knowledge and skills to the community about the application of environmentally appropriate technology that is Biopori Absorption Hole technology (LRB). This activity is useful to increase the ground water reserves and reduce the waste as well as to produce compost. Partners of this activity are 2 groups of residents Rukun Tetangga (RT) that is RT 04 and RT 06 Village Tabing Banda Gadang, District Nanggalo, Padang. This form of activity consists of lectures and practices of making biopore infiltration holes. The practice of making the biopore infiltration hole involves community participation. Many of the created biopore holes are made up of 10 holes per each RT. The hole is 10 cm in diameter and 100 cm in depth. The holes that have been made therein incorporated organic waste in the form of remnants of vegetables, paper, fruit peels and others - others. Thus LRB is useful in reducing waste, increasing groundwater reserves, reducing the flow of surface water that causes flooding and will reduce the dangers of drought.

Jagung merupakan salah satu komoditi unggulan Desa Kampung TangahKecamatan Lubuk Basung, dimana produksi jagung dari tahun ketahun mengalamipeningkatan. Dari setiap panen jagung diperkirakan jagung (rendemen) yang dihasilkansekitar 65%, sementara 35% dalam bentuk limbah berupa batang, daun, kulit, dan tongkoljagung (Anonimous, 2003). Tingginya produksi jagung tiap tahunnya berdampak padatingginya limbah yang dihasilkan terutama limbah tongkol jagung. Limbah yangdihasilkan pasca panen jagung ini yang paling mudah dan bisa dilakukan petani untukmenangani limbah tersebut adalah dengan membakarnya. Dari pengamatan lapanganditemukan bahwa tongkol jagung tidak termanfaatkan dan dibuang atau dibakar.Diketahui bahwa dari tongkol jagung yang dihasilkan sangat kaya akan karbohidrat yangdapat digunakan atau diolah menjadi produk yang bermanfaat dan bernilai ekonomiuntuk kehidupan manusia. Dengan pemanfaatan teknologi, sebenarnya limbah tongkoljagung tersebut bisa dikembangkan menjadi suatu produk yang lebih bernilai ekonomiyaitu diantaranya dijadikan sebagai briket.Kegiatan yang akan dilakukan ini dapat dijadikan sebagai alternatif pemecahanmasalah dalam mencapai tujuan serta harapan masyarakat tentang pemanfaatan limbahkhususnya tongkol jagung dan sejalan dengan tujuan dari program pengabdian denganmerangkul kelompok masyarakat supaya terciptanya lingkungan, kualitas hidup yangsehat dan menjadi desa energi. Pada program ini akan memberdayakan 2 kelompoktani yaitu Kelompok Tani Harapan dan Kelompok Tani Bangkit yang merupakan petanijagung yang hasil jagungnya dijual untuk diolah menjadi makanan ternak. Biasanya sisatongkol jagung yang telah diambil jagungnya mereka buang dan dibakar begitu saja.Padahal tonggol jagung ini bisa diolah untuk menjadikan briket yang mempunyai dayajual. Oleh karena itu tim pengabdian tertarik melakukan pengabdian di bidang ProgramKemitraan Masyarakat dengan judul “Produksi Briket Arang dengan PemanfaatanLimbah Tongkol Jagung di Desa Kampung Tangah Kecamatan Lubuk Basung”..Kegiatan yang akan dilakukan adalah bagaimana memproses tongkoljagung yang biasanya dibuang sampai menjadi briket yang mempunyai daya jual. inidimulai dari bagai mana proses mulai dari bagaimana mengolah tongkol jagung sampaimembuat alat dengan output berupa briket sebagai energi, dan dalam pelaksananya dalamwaktu 8 bulan dengan survey awal ke lapangan, melakukan pertemuan/diskusidilanjutkan pengambilan data serta kesepakatan dengan mitra.

Based on field observation, The production of stripping overburden at PT. Pengembangan Investasi Riau on November 2020 didn’t reach target. It was caused by the high number of losstime that occur during the production process.Digging-Loading Equipment used for Stripping Overburden on one of fleet is 1 Unit 1 unit Excavator Kobelco SK480LC (EE01) with Hauling Equipment, 9 unit Dump Truck Quester CWE 370 (DT78, DT81, DT84, DT85, DT86, DT87, DT89, DT90 dan DT91). To determine potential of improvement from a production process and effectiveness of using equipment, then an analysis called Overall Equipment Effectiveness (OEE) was carried out. OEE value for actual Digging-Loading Hauling Equipment indicates a very low value (< 85%). Next, used the Fishbone Diagram to find cause and effect from high number of losstime that occurs on the Equipment. Finally, the loss time is repaired due to human factors with the smallest standard tolerance method. After analyzing and improving with these methods, the production of Stripping Overburden on the fleet theoretically increased ± 2000 bcm from the previous production. OEE value still shows a fairly low value (< 85%) from World Class OEE Standard (> 85%). In addition, operational cost for digging-loading dan hauling equipment also increase along with the increase in production.

Abstract. Zones 1 and 3 are one of the mining locations in the PT.BSP area, in the andesite mining process in Zone 1 it uses 6 pieces of conveyance and 1 loading device and in the stripping process for loads in zone 3 uses 4 pieces of conveyance and 1 piece of loading tool. This happens because of lack of discussion The composition of mechanical devices and the amount of waiting time that occurs on the conveyance. The purpose of this study is to count products in zone 1 and zone 3, count equipment in zone 1 and zone 3, get funds and calculate queuing times for production in zone 1 and zone 3, and get a matching factor equal to 1. In this research the theory and field data are combined so that it can be completed. And the results of data processing will be analyzed so that a meeting can be generated later. Based on the results of the study can be concluded. First, productivity of komatsu PC200 in Zone 1 is 249.9 tons / hour and productivity of komatsu DT FM500TI is 357 tons / hour. In Zone 3 komatsu PC 200 productivity is 175 bcm / hour and komatsu DT FM500TI 260 productivity is 160,448 bcm / hour. Second, the composition of the available equipment for Zone 1, namely 1 loading device and 6 conveyances, Zone 2, 1 loading device and 4 conveyances. Third, trying to reduce the queue time to make improvements to the composition is not necessary because of increased damtruk added. Fourth, analyze the calculations at Zone 1 = 0.363 and Zone 3 = 0.6140 MF <1 unit. It means that the working factor of the loading tool is less than 100% and the working factor of the conveyance is more than 100% or the ability of the excavator is less than the working of the conveyance due to the large waiting time of the conveyance.Keywords: production capacity, matching factors, queuing theory, andesite mining, mining equipment
