Abstract

Every asset in the operation of certain services, transportation or services will experience a change in each period of time. Replacement is made on an asset that is damaged, operating costs are too high, or a change in technology makes an equipment unusable. CV. X is a company engaged in providing services for transportation fleets, one of which is dump trucks. Today, companies are often faced with complex replacement problems and only apply the depreciation method to determine the life of their equipment. This study aims to propose determining the age of dump trucks with optimal replacement intervals and to find out the hourly usage costs incurred by the company at the optimal replacement age. This method uses the hourly cost as the basis for determining the optimal replacement life. The research data is in the form of secondary company data consisting of maintenance data such as vehicle purchase price data, fuel consumption, lubricant consumption, labor wages, annual operating hours, productivity, rental rate, interest rate value, and income tax rate. The parameters are in 1000 hour intervals. The optimal replacement life for dump trucks is in the interval of 30,000 hours – 40,000 hours or 12-16 years. The hourly usage cost at the optimal replacement life interval with the productivity approach is $159.74 and the hourly usage cost with the rental rate approach is $104.64.

Abstract

Increased consumer demand has an influence on production results. Pure chips SMEs have obstacles in meeting their needs for raw materials such as sweet potatoes and cooking oil. The main raw materials are obtained from sweet potato farmers and cooking oil producers. Accurate and maximum calculation of raw materials is needed so that SMEs do not have problems in facing shortages or excesses of main raw materials. This research aims to assist pure chips SMEs in managing the amount of inventory of core raw materials to be produced into snacks. Research on the production of sweet potato and cooking oil supplies was carried out using a quantitative descriptive approach. The data obtained comes from pure chips UKM. Then the data will be analyzed using the reorder point method. From the calculation results, it was found that pure chips SMEs had to re-order sweet potato raw materials of around 8 kilograms per day and 3 liters of cooking oil raw materials per day.

Abstract

Measuring the company level of productivity performance is a very important thing to do to see and evaluate achievements and improvements to productivity levels that are not yet optimal. This case study was taken from the leather bag UKM which is currently experiencing a decline in productivity during the 2020 period. With the increase in working hours, the company must increase workers' overtime costs. In this research, the method used to measure the level of company productivity is the objective matrix or OMAX method and this research refers to the OMAX steps, namely determining productivity criteria on the production line, determining weights, determining levels on the objective matrix, calculating the productivity index, and productivity analysis with a traffic light system. The research results show that the average value of overall productivity in 2020 is 4,388 The highest productivity index was achieved in August amounting to 67,01%. From the traffic light system, it is known that the worst indicator of productivity is the defect factor, so improvements need to be made regarding this.

Abstract

Suhu di ruang produksi PT Cahaya Alam Sejati serta mengevaluasi apakah suhu tersebut sesuai dengan standar yang diatur dalam Permenkes No. 70 Tahun 2016 tentang Standar dan Persyaratan Kesehatan Lingkungan Kerja Industri. Suhu di ruang produksi diukur secara rutin pada tiga waktu berbeda, yaitu pagi (07:00 WIB), siang (15:00 WIB), dan malam (23:00 WIB), selama 30 hari berturut-turut. Pengukuran dilakukan menggunakan alat pengukur suhu yang sesuai standar, dengan tujuan untuk melihat variasi suhu yang terjadi sepanjang hari. Hasil penelitian menunjukkan bahwa suhu ruangan pada siang hari melebihi batas maksimal yang ditetapkan oleh Permenkes, yaitu 30°C untuk pekerjaan ringan dan 29°C untuk pekerjaan sedang. Suhu pada siang hari tercatat antara 33,3°C hingga 37,6°C, yang jauh di atas standar yang diperbolehkan. Sementara itu, pada pagi dan malam hari, meskipun ada beberapa pengukuran yang memenuhi syarat, suhu di beberapa titik juga tetap melebihi ambang batas yang diperbolehkan. Kondisi suhu yang tidak sesuai ini berpotensi menimbulkan dampak negatif terhadap karyawan, seperti peningkatan risiko heat stress, dehidrasi, dan penurunan produktivitas akibat ketidaknyamanan kerja. Untuk mengatasi hal tersebut, penelitian ini memberikan rekomendasi kepada PT Cahaya Alam Sejati agar melakukan perbaikan sistem ventilasi dan pendinginan di ruang produksi, serta melakukan pemantauan suhu secara berkala untuk memastikan kondisi lingkungan kerja tetap sesuai dengan standar kesehatan yang berlaku. Penelitian ini diharapkan dapat memberikan kontribusi signifikan dalam menciptakan lingkungan kerja yang lebih sehat dan produktif, serta mematuhi regulasi yang ditetapkan oleh pemerintah terkait kesehatan lingkungan kerja di industri manufaktur.

Abstract

Penelitian ini bertujuan untuk mengkaji penerapan Metode Reorder Point (ROP) dalam manajemen pengendalian persediaan stok bahan baku produksi mesin Chicago Blower di PT. Super Andalas Steel. Sebagai perusahaan yang bergerak di bidang perbengkelan, pengelolaan persediaan bahan baku menjadi hal krusial guna menghindari masalah kelebihan maupun kekurangan stok yang dapat mengganggu proses produksi dan menurunkan kepuasan pelanggan. Masalah kelebihan persediaan dapat menyebabkan biaya penyimpanan yang tinggi, sedangkan kekurangan persediaan dapat menghentikan produksi dan menunda pengiriman produk. Penelitian ini merekomendasikan penerapan sistem manajemen persediaan yang efektif melalui penetapan titik pemesanan ulang (ROP) yang didasarkan pada analisis tingkat permintaan dan lead time. Dengan menggunakan metode peramalan Exponential Smoothing, penelitian ini berhasil menghasilkan titik ROP yang akurat, sehingga perusahaan dapat menjaga keseimbangan antara jumlah bahan baku yang tersedia dan kebutuhan produksi. Hasil penelitian menunjukkan bahwa penerapan metode ROP dapat mengoptimalkan persediaan, mengurangi biaya operasional, dan meningkatkan efisiensi produksi serta kepuasan pelanggan di PT. Super Andalas Steel. Penelitian ini diharapkan dapat memberikan kontribusi yang signifikan terhadap manajemen persediaan bahan baku di perusahaan tersebut.
