Abstract

One of the industries that process latex and lumps into sheets with quality RSS 1, RSS 2, and cutting is PT. XYZ is located in Banjar Regency, South Kalimantan. In the production process, PT. XYZ produces more RSS 2 and cutting products compared to its main product, namely RSS 1. This is due to various factors that result in a decrease in product quality. The purpose of this study is to analyze the quality control of RSS by using statistical quality control (SQC). The tools used are check sheets, Pareto diagrams, P control charts, and cause and effect diagrams. Based on the research that has been done, it is found that a lot of data are outside the control limits of UCL and LCL, which are caused by the initial acceptance of raw materials and the smoking process that is not up to standard. Improvements that need to be made by PT. XYZ is by maintaining the cleanliness of raw materials and placing operators to research on the RSS processing process.

Abstract

Produk SIR 20 yang diproduksi oleh PT. XYZ sering mengalami cacat produk dan jenis cacat yang paling sering terjadi adalah cacat white spot. Tujuan penelitian ini adalah menganalisis penyebab white spot pada SIR 20 di PT. XYZ. Metode yang digunakan dalam penelitian ini adalah metode six sigma. Berdasarkan hasil analisis yang telah dilakukan, ditemukan penyebab cacat white spot terdiri dari beberapa faktor yakni faktor lingkungan, proses produksi, material, mesin dan peralatan, manusia dan lingkungan. Faktor utama cacat white spot adalah karena lingkungan seperti curah hujan yang tinggi. Hasil analisis penelitian menunjukkan bahwa jumlah cacat white spot di PT.XYZ berada di tingkat nilai sigma 2,48 yang berarti termasuk dalam rata-rata industri Indonesia dengan kemungkinan kerusakan sebesar 163889 untuk setiap satu juta produksi SIR 20. Nilai ini masih cukup tinggi sehingga diperlukan beberapa upaya untuk mengurangi terjadinya cacat white spot pada produk SIR 20 di PT. XYZ yaitu dengan lebih memperhatikan kondisi penanganan jika curah hujan tinggi, serta perlu adanya sistem terintegrasi pada proses pengolahan untuk mengetahui kualitas material (bahan baku) yang masuk, kondisi mesin dan peralatan, dan SOP untuk tenaga kerja (manusia).

Abstract

In a combustion engine, to generate torque, a combustion and compression process is required. Apart from obtaining mechanical energy, the combustion results also produce exhaust emissions, which can result in a polluted environment. This research aims to determine the influence of torque and exhaust gas emission modeling by using variations in the number of filters using simulation software. This research is descriptive and quantitative research with an experimental method. This research uses a Dyno test tool and a Gas Analyzer from this research to find out data from the exhaust that has been varied. The addition of a filter reduces the torque value by 1.7%. The presence of a filter on the catalytic converter has been proven to reduce levels of exhaust emissions that are harmful to the environment (CO, HC). Of the variations in the number of catalytic converters, filter number 2 is the best, producing 9.71 hp with CO emission levels of 1.7% and HC 553 PPM.
