Abstract

Permasalahan sampah adalah bagian yang tidak dapat di pisahkan dari kehidupan manusia, karena didalam kehidupan sehari-hari manusia pasti menghasilkan sampah. Berdasarkan data Asosiasi Industri Plastik Indonesia (INAPLAS) dan Badan Pusat Statistik (Kompas.com2018) bahwa produksi sampah plastik di Indonesia mencapai 64 juta ton/tahun. Berangkat dari masalah tersebut, pemerintah Kabupaten Bogor mulai memunculkan berbagai macam program sebagai solusi menangani permasalahan sampah . Salah satu Desa yang menjadi percontohan adalah Desa Sadeng di Kecamatan Leuwi Sadeng dengan program KRL (Kampung Ramah Lingkungan) .“KRL Darussalam”adalah KRL yang ada di Desa Sadeng RT.01/RW.01 dan telah berjalan selama ±3 tahun . Program kerjanya adalah 1) Pengelolaan Sampah & Lubang Resapan Biopori (LRB), 2) Tata kelola lingkungan & Penghijauan, 3) Sanitasi. Melalui program kerja tersebut, masyarakat diharapkan ikut berperan aktif dalam pengelolaan sampah untuk meningkatkan kesejahteraan kehidupan keluarganya, karena dari hasil pengamatan terdapat beberapa sampah yang memiliki nilai ekonomis jika dimanfaatkan kembali. Upaya yang dilakukan yaitu melakukan penyuluhan kepada masyarakat akan pentingnya menjaga lingkungan dalam program KRL dengan harapan masayarakat lebih antusias dalam melaksanakan program guna meningkatkan kesejahteraan kehidupan keluarga Desa Sadeng.

Abstract

A rubber cover flyerroll on an insert machine that has been operating for 3600 hours and is damaged, so an analysis is needed to determine the cause of the damage and a process to overcome the damage and the same failure occurs in the future. This flyer roll functions as a billing statement folder before being inserted into an envelope with dimensions of 28 mm (OD) x 284 mm (L). To find out the cause of the damage, several tests were carried out, namely destructive testing and chemical composition testing. Physical tests carried out include hardness test, tensile strength test, modulus test, elongation break test, density test, and abrasion resistance test. resistance test) and in this study a chemical composition test was conducted. From the test results, it can be seen that the hardness value is still within the tolerance limit, which is 94 shore A with a tensile strength value of 31.7 N/mm2 and the results of the chemical composition are dominated by polyurethane rubber at 62.9% and polystar at 23%. So from the tests that have been carried out, it can be concluded that the cause of the damage that occurs to the rubber cover flyer roll is caused by improper maintenance methods, machine maintenance that is not carried out and standard operational procedures (SOPs) that are not carried out according to the recommended maintenance process

Abstract

This research is an initial research in the development of cars with compressed air engine drivers. Modifications are made to the engine of 2-stroke motorized vehicles fueled by gasoline. Pressurized actuators using selenoid valves are ordered based on the piston position obtained from the proximity sensor. When the proximity sensor detects the piston is in the TMA position, the selenoid valve is ordered to open so that pressurized air enters the combustion chamber and pushes the piston to move to the TMB and turns back to TMA. The selenoid valve will close again when the proximity sensor detects that the piston is moving from TMA to TMB. Pressurized air is given to move the piston to produce a spin on the wheel. Air pressure is given at 0.92 bar to 2.36 bar resulting in a maximum rotating speed of 1035 rpm, torque of 1.33 Nm, and maximum power of 0.71 kW based on the results of static testing. This research will continue to be developed to optimize the torque and power produced so that cars driven by compressed air engines can be produced.
