Abstract

Compressor at PT. Es Muda Perkasa that commonly failure is at unit D. So that need to optimize the compressor at unit D with finding the failure of the parts of the compressor and making the schedule of maintenance program to minimize the failure of the ice machine. This study using Reliability Centered Maintenance (RCM) method, which applicate Grey FMEA to determine the priority of the machine maintenance. After conducting and implementing the RCM method, it was found that the failure occurs at Low-Pressure and High-Pressure Pump at compressor unit D, and sub-part failure happen on bearing, due to small coefficient, which is 0.566 where it become primarily failure component. For the next maintenance, using schedule on condition task on bearing parts of the machine could minimize the failure of the parts on the machine

Abstract

Mesin distribusi menjadi hal yang penting dalam perusahaan Daerah Air Minum (PDAM) Tirta Daroy Banda Aceh. Kebutuhan supply air bersih meningkat dengan bertambahnya penduduk dan peralatan atau mesin distribusi yang terdapat didalam Perusahaan Daerah Air Minum (PDAM) akan senantiasa mengalami penurunan efisiensi, tingkat kesiapan, keandalan (reliability) dan kualitas bentuk kerja (performance) yang menyebabkan keadaan menjadi buruk, sejalan dengan lamanya pemakaian dan umur mesin. Hal itu akan menyebabkan kerugian bagi perusahaan, oleh karena itu, perusahaan harus berusaha agar mesin dan peralatan berfungsi dengan baik sehingga penyuplaian air bersih berjalan lancar. Tujuan penelitian ini adalah untuk mengetahui efektifitas mesin KSB dan TORISHIMA serta membandingkan nilai OEE perusahaan dengan standar Overall Equipment Effectiveness World Class. Metodologi yang digunakan yaituOverall Equipment Effectiveness. Adapun hasil penelitian ini dapat disimpulkan yaitu nilai rata-rata OEE yang didapatkan dari mesin KSB dan TORISHIMA mulai dari 90,53% hingga 94,00%. Adapun hasil tersebut jika kita bandingkan dengan JIPM world class, maka untuk nilai Overall Equipment Effectiveness perusahaansudah mencapai standar yang ditetapkan yaitu 85%.

Abstract

Tujuan penelitian adalah untuk mengetahui bagaimana manajemen program parenting dapat mengurangi dampak kecanduan gadget anak-anak di lingkungan RW 30 Cimindi Hilir. Banyaknya anak-anak yang bermain gadget di lingkungan RW 30 karena adanya sarana Wi-fi yang dapat diakses secara gratis. Penelitian ini menggunakan metode deskriptif dengan pendekatan kualitatif, yaitu dengan teknik wawancara dan observasi. Adapun responden dalam penelitian ini adalah penyelenggara program penyuluhan yang berjumlah 2 orang sebagai informan utama dan orang tua anak-anak berjumlah 12 orang sebagai informan tambahan di lingkungan RW 30 Cimindi Hilir Kelurahan Cimahi Selatan. Hasil dari penelitian ini disimpulkan sebagai berikut: (1) Perencaan program penyuluhan parenting tertata dengan baik sesuai masalah yang dihadapi, 2) Pada pelaksaan penyuluhan diperoleh data bahwa para orang tua belum sama sekali mendapat arahan atau acuan secara sistematis. 3) Dengan program parenting tingkat pengetahuan orang tua terhadap gadget meningkat, sehingga mereka memiliki cara/ pola untuk mengalihkan anak-anak mereka dari bermain gadget setiap hari.

Abstract

Limbah kulit durian yang menumpuk akan menjadi sumber pencemar jika tidak diberdayakan dengan benar. Salah satu upaya untuk memberdayakan limbah kulit durian adalah mengolahnya menjadi produk bioetanol. Kulit durian mengandung 5% elemen zat tepung dan lignin yang mengandung 50-60% selulosa. Selulosa merupakan karbohidrat utama yang disintesis oleh tanaman dan hampir 60% penyusun struktur. Karbohidrat adalah bahan dasar dalam pembuatan etanol. Penelitian ini menggunakan limbah kulit durian untuk produksi bioetanol melalui proses fermentasi dengan penambahan Saccharomyces cerevisiae (ragi). Penggunaan enzim alphaamilase dan enzim glukoamilase untuk pemecahan selulosa dalam limbah kulit durian sehingga produksi bioetanol semakin meningkat. Sampel limbah kulit durian ini menunjukkan hasil dimana pH 4.5  dan suhu 35°C merupakan pH dan suhu fermentasi sampel limbah kulit durian yang memiliki persentase maksimum produksi bioetanol. Hal ini membuktikan bahwa konsentrasi etanol dalam air secara bertahap meningkat seiring dengan meningkatnya pH dan mencapai persentase maksimum produksi bioetanol pada pH 4,5 dan menurun pada pH 5. Melalui penelitian ini diharapkan mampu mengurangi pencemaran lingkungan dari penumpukan limbah kulit durian dan menjadi bahan bakar alternatif baru produksi bioetanol.

Abstract

Bicameral is the term for a representative system consisting of two chambers (cembers) or two bodies, consisting of an upper house and a lower house in Indonesia known as the DPR RI and DPD RI which aims to achieve good governance. (good governance) as well as the achievement of checks and balances between State Institutions, especially in the Legislative Institution, which is one of the most important elements in the administration of the State. This institution has the main function in regulation, budgeting, and supervision. Although in practice this system is not perfect due to the limited role of DPD in the Political System in Indonesia. Thus, the existence of two chambers in the legislature is expected to achieve two controls in every policy issued, so that it will tend to have a positive impact on the progress of the country and in the end good governance will be achieved as the ultimate goal of a country.

Abstract

Product quality is an important factor that affects the level of development and progress of a company. Companies that operate without paying attention to the quality of their products are tantamount to losing hope for the future of the company. The resulting product must always be checked for compliance with the established standards, so that the damage that occurs to the product can be reduced and eliminated. This study aims to analyze the quality control of raw materials using the seven tools method on sweet bread products at UD. Sarigut Bakery Banda Aceh. This research data is primary data obtained by researchers from questions posed to original sources and also observations of researchers at the location directly. The results of the study found that the quality control of raw and supporting materials was not good enough because the company was not able to maintain the quality standards and brands of materials set by using non-standard materials with lower quality levels. As for the feasibility of the storage warehouse, the control is quite good because the arrangement and placement of materials is orderly and the cleanliness of the warehouse and factory is quite well maintained. Disability caused by working hours is R² = 0.1336 or 13.36%. Defects due to long storage of raw materials are R² = 0.7254 or 72.54%. Meanwhile, defects due to the use of non-standard wheat flour raw materials are R² = 0.8621 or 86.21%. Non-standard raw materials are the biggest factor in causing product defects, this is caused by the condition of substitute materials that are not up to standard, which results in high water content in bread. Keywords: Quality control of raw materials, seven tools, sweet bread
