Abstract

PT. Selamat Sempurna, Tbk is a company that manufactures  automotive parts, namely car filters. This filter product has many part numbers. In this company has one of the production lines, namely Line Seat Press Shop, this line produces components from filters, namely seat components. Seat is the main part of the filter component that functions as a filter holder to the engine. This Seat component consists of several part numbers (shapes or variations) following the filter product, and some part numbers handled by the manual engine B070 & L224 will affect the changes in the production engine settings. This production machine includes machines that require time in a slow setup process for switching dies when switching from one part number to another part number compared to other machines, because the element of the process setting is long. With a fishbone diagram, the root cause of the Change Over Part long problem on the machine is from the method category (there is no preparation desk dies and there is not separation of external setup and internal setup). Previously the time needed for Change Over Part was 1961 seconds. After knowing the root cause of the problem and the improvement of the time needed is only 866 seconds. The time difference is 1067 seconds, so save on average time 1095 seconds or 18 minutes / setup. Keywords: Filter product, Change Over part (COP), Fishbone Diagram, Setup, Process Elements.

Abstract

This research is motivated by data showing the productivity of monthly checking of variable speed belts by the finishing department which was only achieved 2 times during the 2021 period. For this problem, researchers conducted research aimed at increasing the results of checking variable speed belts. The objectives to be achieved in this study include: (1) Increase the productivity of the variable speed checking department. (2) Optimizing the existing information management system with the addition of automation features. (3) Knowing the results of the implementation of an information management system that has been optimized for the productivity of checking belt variable speed. The data used are primary data and secondary data. Decision making for improvement is made with the AHP method. System descriptions are done using UML. Analysis of the current system using use case diagrams and system testing using the black box method. The results showed a decrease in the time needed for the variable speed belt checking process from 7 minutes 21 seconds to 7 minutes 6 seconds, so that the checking results increased by 9.19% from an average of 6.91 S / M / H to 7.545 S / M / H. Keywords: Productivity, AHP, UML, use case, black box

Abstract

Diare pada balita masih menjadi masalah kesehatan masyarakat yang penting di Indonesia. Persepsi keseriusan penyakit diare yang rendah merupakan kendala upaya menurunkan angka kesakitan diare. Penelitian yang menggunakan desain cross sectional ini bertujuan menguji hubungan antara faktor pengetahuan, pengalaman kontak, dan kepercayaan, dengan persepsi ibu terhadap diare pada balita. Populasi pada penelitian ini adalah ibu balita yang bermukim di Kecamatan Bekasi Utara, Jawa barat. Dari hasil penelitian terbukti bahw pengetahuan, pengalaman kontak, dan kepercayaan berhubungan secara bermakna dengan persepsi ibu terhadap diare pada balita. Ibu balita yang berpengetahuan rendah berisiko 2,5 kali untuk berpersepsi diare sebagai penyakit biasa daripada ibu yang berpengetahuan tinggi (OR: 2,535; 95%CI: 1,321 – 4,866) setelah variabel pendidikan dikendalikan. Ibu balita yang tidak pernah berpengalaman kontak berisiko hampir 5 kali lebih besar untuk berpersepsi diare sebagai penyakit biasa daripada ibu balita yang pernah kontak (OR: 4,761; 95% CI: 1,853 - 12,235). Ibu balita dengan kepercayaan rendah berisiko 0,4 kali untuk mempersepsikan diare sebagai penyakit biasa lebih kecil daripada ibu dengan kepercayaan tinggi setelah variabel jumlah balita dikendalikan (OR: 0,392; 95%CI: 0,195 - 0,765). Upaya memperbaiki persepsi ibu balita disarankan dengan meningkatkan program promosi kesehatan yang dilakukan melalui peningkatan pengetahuan, menciptakan pengalaman dengan model simulasi, serta merasionalkan kepercayaan tentang diare pada balita di masyarakat. Diarrhea among under-five children is still a major problem in developing countries such as Indonesia. The low perception to the seriousness of diarrhea is one of the obstacles in decreasing the diarrhea frequency. Using cross sectional design, this research aims to find the relationship between knowledge, contact experience, and belief about diarrhea on under five children with the perception of mothers towards the seriousness of diarrhea. The research population is mothers with under five children in Bekasi Utara district, and 175 subjects were selected randomly across 6 regions (kelurahan). This research showed that knowledge, contact experience and belief have significant relation with the perception towards the seriousness of diarrhea on under five children. Mothers who had limited knowledge had chance 2,5 times more than mothers who had wide knowledge to perceive that diarrhea was not serious (OR: 2.535; 95%CI: 1.321 – 4.866) after education variable was controlled. Mothers who had no experience with diarrhea had chance almost 5 times more than mothers who had experience to perceive that diarrhea was not serious (OR: 4.761; 95%CI: 1.853 – 12.235). Mothers who had low belief had chance 0.4 times more than mothers who had high belief to perceive that diarrhea was not serious (OR: 0.392; 95%CI: 0.195 – 0.765) after the number of under five children was controlled. The effort to improve the perception of mothers towards diarrhea can be conducted by improving the program to promote health, such as enhancing the knowledge/ awareness, creating contact experience by simulation model, and by rationalizing belief about diarrhea.
