Abstract

Weir is one of the water buildings built across the river. Weirs are needed to elevate the river water level so that it meets the elevation of irrigation needs. In very diverse watershed conditions, it is very possible that a dam was built in a river channel that is not ideal because the river channel turns so that the building becomes less safe. To be able to know the safety of the weir from erosion that can cause the weir to collapse and break or overturn, it is necessary to conduct an experimental laboratory research on the position of the weir in the downstream of a river bend. Research related to its effect on sediment transport, especially in the formation of basic configurations needs to be known, because erosion at the bottom is the initial process of weakening the weir security. This research was conducted in the Hydraulics and Coastal Laboratory of FT. The irram in a river flume with a length of 8 m and a width of 50 cm. Weir test is carried out with 4 variations of discharge and 3 variations of the position of the weir downstream of the channel bends. Sedimentation data were analyzed by the methods of Mayer, Peter, Muler (M.P.M), Einstein and Shinohara-Tsubaki and topographic data analysis using the Surfer program. The results showed that in general the largest sediment transport occurred in the position of weir I at a distance of ½ channel width downstream of the center of the channel bends for all tests, with the magnitude of sediment transport occurring from the MPM method Qs = 1x10-4 m3 / dt / m, Einstein Qs = 6,371x10-6 m3 / sec / m, and Shinohara-Tsubaki Qs = 1,7951x10-4 m3 / sec / m. More dominant scouring occurs at the foot of the weir downstream, with the basic configuration formed in the form of antidunes and standing waves, and based on the Froude (Fr) flow rate including subcritical flow (Lower Flow Regime) with the basic configuration form of ripples and dunes

Abstract

Penimbung Village is one of the villages in the Gunungsari District, West Lombok Regency. Penimbung Village has an area of 420 hectares or 4.2 acres, which consists of 7 main hamlets and 3 preparatory hamlets. The waste problem in Penimbung Village is a serious problem because there is no Final Garbage Disposal Site (TPS). The lack of public knowledge regarding the use of organic waste is also a major problem. The purpose of this activity is to increase public knowledge regarding the use of organic waste to become liquid organic fertilizer so that it has use value for the environment. The method used in this activity is counseling and demonstration. The community paid attention to the material presented and then continued with a demonstration of making and assisting in the manufacture of liquid organic fertilizer. From the evaluation results, it was found that the community felt helped by this activity and gained knowledge about how to process household waste, especially organic waste. Community empowerment activities in Penimbung Village through training in the manufacture of liquid organic fertilizer have again introduced the community to the concept of advanced and sustainable agriculture where the utilization of waste, apart from providing use value for the environment, can also reduce expenditure on purchasing fertilizers for agriculture.

Abstract

Selama ini masyarakat menganggap biji rambutan sebagai limbah tidak terpakai padahal biji rambutan memiliki banyak manfaat untuk kesehatan. Tujuan kegiatan yang dilakukan oleh mahasiswa KKN Tematik UNRAM adalah agar masyarakat dapat berkreasi dan berinovasi terhadap limbah biji rambutan untuk menjadi produk yang bernilai jual. Kegiatan ini dilakukan di Desa Penimbang, Kecamatan Gunungsari, Nusa Tenggara Barat. Pendekatan yang digunakan dalam kegiatan ini adalah Learning by Doing. Tim mahasiswa KKN Tematik UNRAM belajar dengan mempraktekkan langsung cara mengolah biji rambutan dengan alat dan bahan yang sudah disiapkan. Pendekatan ini diharapkan lebih efektif untuk mencapai target luaran dalam kegiatan KKN di Desa Prnimbunh. Hasil pelaksanaan kegiatan Kuliah Kerja Nyata (KKN) Tematik mampu memberikan informasi dan inovasi tentang pengolahan limbah biji rambutan sehingga masyarakat mampu mengolah limbah biji rambutan menjadi sebuah usaha bisnis yang kreatif, yang mampu menunjukkan kreatifitas dalam mengubah limbah yang tidak terpakai menjadi produk yang bernilai. Selain itu, kegiatan ini juga bisa menjadi salah satu pilihan untuk mengurangi limbah khususnya biji rambutan.
