Abstract

Sebuah perusahaan yang bergerak dibidang tekstil di Pekalongan, mengolah serat kapas menjadi benang jadi. Produksi benang melewati beberapa proses yaitu blowing, carding, pre drawing, unilab, drawing breaker, drawing finisher, roving, spinning, winding dan packaging. Ditemukan banyak produk cacat, sehingga perusahaan perlu meningkatkan kualitas guna menjaga kepercayaan konsumen. Penelitian bertujuan mengetahui pengendalian kualitas di perusahaan saat ini dan memberikan usulan perbaikan pada proses produksi. Metode yang digunakan Statistical Process Control dengan peta kendali atribut (p chart) dan usulan perbaikan disusun dengan diagram fishbone. Jenis cacat berupa gulungan kotor, full gembos, gulungan jelek, gulungan kecil, ring cones, salah cones, belang uv, dan tanpa ekor. Analisis data produk cacat benang TCM menunjukkan banyak data yang melebihi batas kendali, yang didominasi gulungan kotor sejumlah 143 cones, gulungan jelek 137 cones, full gembos 121 cones. Faktor-faktor yang menjadi penyebab produk cacat antara lain yaitu manusia, mesin, dan lingkungan, sehingga perlu diperhatikan lebih lanjut untuk perbaikan kualitas pada perusahaan.

Abstract

This study aims to analyse the relationship of disaster factors to the level of preparedness of students in Central Java in facing disasters. This research uses quantitative methods, because data collection in research is related to numbers and uses statistical analysis. The quantitative approach in this study uses the Structural Equation Modelling (SEM) method. Sampling was carried out by purposive sampling method or an assessment that was taken if it met certain criteria in accordance with the research topic, the sample used was 361 respondents. The method used in this research is SEM analysis, which is a multivariate statistical technique that analyses the relationship between variables. Independent variables include knowledge, attitude, policy, environment, training and religiosity. The dependent variable is preparedness. The results of research from independent variables that have an effect and have a positive direction are the attitude variable with a T-statistic value of 7,357, the training variable with a T-statistic value of 4,839 and the religiosity variable with a T-statistic value of 2,352. Variables that have a positive direction, but no effect are the knowledge variable and the policy variable.

Abstract

PT. Agricon mostly produces 1L package (bottle) pesticides named Spontan insecticide. This study was conducted to analyze and determine the stock inventory of 1L bottles for determining an effective ordering schedule based on the calculation of safety stock and reorder points to optimize planning and inventory. Material Requirement Planning (MRP) method used to determine the effective scheduling of 1L bottle products. Material Requirement Planning is one method used to determine scheduling with advantages such as reducing inventory, reducing set up costs, and reducing idle time. The proposed order scheme for ordering 1L insecticide packaging bottle improve the company on reducing the frequency for ordering bottles from 7 times to 5 times and inventory is more stable and close to demand quantity

Abstract

Motor bakar internal masih menjadi sistem propulsi utama kendaraan bermotor, didukung oleh infrastruktur yang memadai, ketersediaan bahan bakar, serta kinerja operasional yang andal. Upaya peningkatan performa mesin terus dilakukan, salah satunya melalui rekayasa sistem gas buang. Penelitian ini mengkaji pengaruh variasi diameter dalam Velocity Stack Ring terhadap performa mesin sepeda motor 110 cc. Velocity Stack Ring merupakan perangkat berbentuk cincin yang dirancang untuk meningkatkan proses pembakaran dengan mempercepat aliran udara masuk ke dalam manifold buang, sehingga mampu mengurangi turbulensi aliran. Modifikasi dilakukan pada exhaust manifold dengan tiga variasi diameter internal: 15 mm, 20 mm, dan 25 mm. Evaluasi kinerja meliputi torsi, daya, dan konsumsi bahan bakar spesifik, melalui pengujian eksperimental menggunakan alat uji Dynotest. Hasil penelitian menunjukkan bahwa variasi diameter Velocity Stack Ring memberikan pengaruh signifikan terhadap performa mesin. Torsi tertinggi diperoleh pada variasi 15 mm sebesar 6,93 Nm pada 5618 rpm, meningkat dari kondisi standar sebesar 6,23 Nm pada 5750 rpm. Daya maksimum dicapai pada diameter 20 mm sebesar 6,4 hp pada 7206 rpm, lebih tinggi dibandingkan daya standar sebesar 5,6 hp pada 6982 rpm. Sementara itu, nilai konsumsi bahan bakar spesifik (SFC) terendah tetap diperoleh pada kondisi standar, yaitu 0,127 kg/hp.jam, dibandingkan dengan nilai 0,143 kg/hp.jam pada penggunaan diameter 20 mm. Dengan demikian, modifikasi Velocity Stack Ring terbukti mampu meningkatkan performa mesin, terutama dalam hal daya dan torsi, meskipun disertai peningkatan konsumsi bahan bakar.

Abstract

CV. Istiqomah Furniture is a company engaged in manufacturing furniture located in Klaten, Central Java. The problems that are often faced by CV. Istiqomah Furniture, namely the decrease in worker productivity and the number of final products that are not following company standards. One of the departments responsible for these problems is the service department. The high intensity of work in the service department can cause a mental burden for workers. The purpose of this study is to calculate the mental workload felt byworkers, find out the dominant factors that cause this mental burden, and provide alternative improvements based on the problems faced by the company. The method used in this research is NASA-TLX (National Aeronautics and Space Administration Task Load Index). The results of this study are that the average worker has a high mental workload with a WWL value of 72.11, and the mostinfluential factors are physical and mental needs. Based on these results, the proposed improvements provide sufficient rest time, improve worker safety and comfort, increase work motivation, provide adequate facilities, conduct medical tests, and provide good nutrition.
