Abstract

The industrial sector is currently increasingly competitive and intensively developed through increasingly sophisticated technology. One of the factors supporting the effectiveness and efficiency of production is the engine, so that engine performance needs to be maximized. PT. Nirwana Internar Jaya is a company engaged in the manufacture of pipes using a twin screw extruder machine. The machine does production continuously, so it does not rule out the possibility of downtime. This study aims to determine the optimal maintenance action and determine the maintenance time interval on the twin screw extruder machine using the Reliability Centered Maintenance (RCM) method. The results obtained are that it can reduce the downtime of the twin screw extruder machine from 72.5 hours to 27.5 hours by performing maintenance on heating control system components with maintenance time intervals of 155.15 hours or 7 days, motor cooling fan 739.02 hours or 31 days and blower/fan components with maintenance intervals of 828.08 hours or 35 days. Condition monitoring measures also need to be taken to reduce disturbances that can hinder production activities.

Abstract

Indonesia is one of the countries that have a fairly high level of consumption of fuel oil (BBM), based on data from BPH Migas (2018) throughout 2018 which reached 75 million kiloliters or an average of 1.6 million kiloliters per day. The consumption includes 16.2 million kiloliters of certain types of fuel (JBT), special types of fuel for assignment (JBKP), and general types of fuel around 51.3 kiloliters. The data is growing this study aims to measure the efficiency of reducing imports of fuel oil by utilizing solid waste of palm oil and to make proposals for the formulation of planning scenarios to optimize the functions of the Indonesian palm oil downstream industry. This research method combines quantitative and qualitative methods using the concept of efficiency and the Scenario Planning model. The method used in this paper is to calculate the level of efficiency using quantitative data on oil palm based on the amount of plantation area and the solid waste it produces. Then a mapping of the downstream palm oil industry will be carried out by reviewing the results of previous research as well as data and information obtained from accurate sources. The result is that by optimizing the utilization of palm oil solid waste, 7.4 billion liters of bioethanol can be obtained which can be used to produce biofuels to reduce the level of imports of fuel oil in Indonesia.

Abstract

Corn cobs are a cultural problem in the NTB region because they are very influential at post-harvest harvesting. Poor handling of post-harvest corn cobs is a very serious problem in the area. Where corn cobs are only used by the community in general, making corn cobs as a mosquito repellent, by burning corn cobs. Corn cobs are corn residues resulting from shelling seeds which contain potential compounds that can be biologically transformed into other compounds, namely lignin, cellulose and hemicellulose. For example, making corn cobs chopper as a tool in handling post-harvest results. The purpose of this plan is to produce an efficient corn cob chopping machine so that it is useful for the community in NTB. The results of observations from the previous tool and processing data will be used to make the design size of the corncob chopper according to the real conditions of the previous tool. The results of the calculation of the transmission system of the corn cob chopper showed that the rotation of the electric motor was 1 HP = 1400 rpm, the shaft diameter was 20 mm, the seat belt used type A with a length of 828.4 mm. The materials used in this corncob chopping knife are as follows: knife = stainless steel material, bearing = cast iron, vant belt = rubber, pulley = aluminum, shaft = S35C-D. From the results of testing the corn cob chopper, 2 kg was obtained in 5 minutes.

Abstract

Air merupakan kebutuhan utama manusia untuk menjaga kesehatan dan keperluan non domestik. Dalam upaya memenuhi kebutuhan air tersebut, beberapa wilayah tidak memiliki sumber air yang layak. Masjid merupakan tempat beribadah orang Islam, kebutuhan air di masjid di kategorikan kebutuhan air non domestik. Salah satu masjid yang memiliki permasalahan air bersih adalah Masjid Al-Amin di Desa Cepu, Kecamatan Penanggalan, Kota Subulussalam, Provinsi Aceh.  Dalam upaya memenuhi kebutuhan air bersih di masjid tersebut di desain sebuah Pompa Air Tenaga Surya (PATS). PATS menggunakan energi surya untuk menggerakkan pompa. Alasan desain pompa air bertenaga surya ini untuk memenuhi kebutuhan air masjid serta tidak membebani masjid terhadap tagihan listrik. PATS juga menggunakan sumber energi terbarukan. Tujuan penelitian secara spesifik adalah membuat perencanaan pompa air non domestik berbasis energi surya. Analisis yang dilakukan penelitian ini meliputi radiasi matahari dan kebutuhan daya pompa. Dari analisis tersebut diketahui bahwa kebutuhan air non domestik di masjid Al-Amin adalah sebesar 3.000 liter/hari. Untuk memenuhi kebutuhan air tersebut maka dibutuhkan daya sebesar 0,236 kW yang di suplai dari modul surya. Kata kunci: PATS; air bersih; pompa; modul surya; radiasi matahari.

Abstract

PT. XXX merupakan suatu  perusahaan yang bergerak di bidang manufaktur yang memproduksi atap baja ringan dan reng. Namun, pada Tahun 2020 dalam memproduksi Baja Reng perusahaan tidak mencapai target produksi yang telah ditentukan. Ini dikarenakan mesin yang digunakan sering mengalami downtime. Metode Overall Equipment Effectiveness (OEE) merupakan suatu  metode untuk mengukur efektivitas mesin yang diukur dari availability, performance, dan, quality. Berdasarkan hasil dari penelitian ini menunjukkan bahwa rata-rata nilai OEE sebesar  59,61 % dan faktor losses paling dominan adalah Reduced Losses sebesar 15,81%. Usulan perbaikan yang dilakukan untuk meningkatkan produktivitas adalah perbaikan strategi dan metode kerja, pengadaan fasilitas yang memadai, serta kaizen. Dilakukan simulasi dan didapati peningkatan nilai OEE sebesar 8,72% serta peningkatan jumlah produksi sebesar 7,29%. Juga terdapat beberapa usulan perbaikan yang dapat diberikan dalam meningkatkan efiktifitas dan efisiensi pada mesin yaitu pada break dilakukan sesi istirahat disela kerja, melakukan pelatihan administrasi, membuat penyangga , melakukan inpseksi secara berkala dan juga pembuatan chek sheet maintenance.

Abstract

With many product characteristics, it is very vulnerable in the preparation of products and in the ideal capacity available. This happens in the warehouse. To find the ideal storage, an analysis of the warehouse layout is performed. The purpose of this study is to increase the warehouse's capacity and classify the products that are in the warehouse's storage locations. This Class-Based Storage method is a way of calculating and classifying based on the frequency of product movement. This research was carried out at PT. Cakra Satria Pratama in the warehouse. The results of this study indicate that the placement of the product is not ideal. Therefore, with the results of the proposed layout analysis results in the classification of products, when producing categories A, B and C with category A 53.85% of total products, category B 30.77% of total products and category C 15.38 % of the total products. Keyword: Layout; Class Based Storage Method; Warehouse.
