Get PDFSmartphones are one of the must-have devices for modern society today. With the high demand for smartphones lately, many companies are competing to produce smartphones that suit consumer needs. Indonesia is one of the developing countries where the growth rate of smartphone use can still increase so that many smartphone manufacturers sell their products to Indonesia. From this phenomenon, researchers want to know the level of satisfaction of users of one of the leading smartphone brands in Indonesia and even in the world, namely Samsung. The purpose of this study is to determine what factors are considered good by customers and the company must maintain these services and what things are deemed not good and need to be improved again. This study uses the IPA method to determine the level of conformity between company services and customer expectations and the Kano model used to determine which services are included in the performance, basic, or delighter categories. From the results of these two methods can be integrated using the IPA-Kano integration table. Some things that still need to be improved from Samsung smartphones according to users who have filled out this questionnaire include good quality materials at a good selling price, attractive and modern product designs, product quality has a good price level, sufficient camera quality for purposes daily needs, and bonuses that make consumers satisfied

Get PDFThe sales activity is a very important activity for the development and sustainability of a company. The sales are closely related to the requirement of raw material. By knowing the number of sales, a company can do estimate the amount of raw material required for production. However, so far still be found as a company that has its policies to determine a requirement of raw material as impact not use a raw material control method. The research purpose to determine the amount of sugar raw material requirement based on results number of sales seasoning XYZ with Monte Carlo simulation. Based on the analysis of data processing results. It was found that the number of sales from the simulation results in 2019 was quite high compared to the sales results during 2018 where the difference in sales simulation in 2019 and real data in 2018 was 62,334 kg. In terms of sugar supply, the total requirement for sugar in 2019 is also quite high, namely 186,756 kg, or the difference in requirement between simulation results and real data is 21,818 kg. This shows that the amount of requirement is directly proportional to sales
Agen Based Modeling for Corn Supply Chain Risks Identification and Sales Negotiation in PTPN VIII
Get PDFPTPN VIII is a state-owned company in West Java cultivating several kinds of commodities, and still have three marginal farmlands with a total size of 3000 hectares open for investment for corn. The type of corn that would be produced is corn feed for poultry needs. Three agents are involved in this agent-based model: the farmers (or cooperatives), PTPN VIII, and the buyers of the corn yields. All agents face risks in doing their businesses which hamper or reduce their probability of achieving their business goals. The potential risks are identified using fuzzy reasoning method. The three blocks of farmland have different levels of fertility. Farmers are expected to compete for the hunt of farmland to rent for cultivating corns, until their funds run out. They must prepare the land, procure their best corn seeds, plant and maintain the crops, and eventually harvest, dry and sell their corn yield. The dryness of the corn grains dictates the selling price. The buyers will buy the corns until their demands are fulfilled for the particular season. There will be a negotiation process between agents to reach an agreement. Each agent seeks to achieve its goal. This is why agent-based modelling is employed. Netlogo software is used to develop the model. Based on fuzzy reasoning method the obtained result shows that the most potential risk is quality risk. The negotiation results show that when both buyer and seller experience heightened degree of risk appetite, the shortest negotiations are achieved
A Survey of the Thickness of the Shoe Sole among Junior High School Students in Greater Jakarta for Shoe Correction in Seat Height-Popliteal Height Equation
Get PDFThis paper aimed to present a survey result of the thickness of the shoe sole among junior high school students in Greater Jakarta, Indonesia. A number of 160 samples of the shoe wearing by junior high school students (85 boys and 65 girls) from Grade 7-Grade 9 was measured. The thickness of the sole of the shoe wearing by them were measured. The results were presented in mean and SD for each grade and gender. T-test results showed that no significant differences were found for thickness of the sole of the shoe wearing by boys and girls within the same grade. Anova test results also revealed that no significant differences were found for thickness of the sole of the shoe among boys in Grade 7-9 (F=0.54, p=0.58) and girls (F=1.06, p=0.35). Findings in this study revealed that a 20mm shoe correction, as often used by many researchers, which is added to the popliteal height to dimension the seat height (SH) is appropriate to be used for population under study. The results of this study provided sufficient justification for the use of a 2 cm shoe correction (SC) in addition to popliteal height when determining seat height of the chair

Pengukuran Produktivitas dengan Metode Overal Equipment Effectiveness dan OMAX di Lini Produksi TMM1 dan TMM2 PT. MTG
No full textPT MTG is a company engaged in the gears and mechanical part component. In the current condition, PT MTG has an effort to improve the company's work efficiency through with an efficiency target of 80%. However, the current problem is that the company does not yet have the right method for evaluating and detecting factors that inhibit increased productivity on the "TMM 1" and "TMM 2" production lines. To find out the right method for PT MTG, two productivity measurement methods are used in total with the Overall Equipment Effectiveness (OEE) method and partially with the Objective Matrix (OMAX) method. In measuring productivity with the OEE method, it can be seen six big losses that occur in each machine on each production line. Whereas in the OMAX method, measurement of productivity is used 4 criteria to determine the company's productivity index, namely (1) Minimization of Defective Products; (2) Optimizing Production Capacity; (3) Efficient Use of Labor; (4) Minimize Absence of Work. Based on the results of data processing and analysis, the average overall OEE value for the "TMM 1" and "TMM 2" production lines is 0.32% and 0.321%. The OEE value still does not meet the JIPM standard of 85%. Whereas in the OMAX results, the average productivity index value of the two production lines is 140.80 per month from the optimal value of 1000. The factor influencing the two methods for not achieving the target is the amount of production per month that differs more than 55% of the production plan. Whereas in OEE, excess production is not considered a loss. So, for the current conditions the right method of measuring productivity for PT MTG is the OMAX Method

Identifikasi Penanganan Kembali Produk Elektronik Rumah Tangga
Get PDFReverse logistics is an item management activity that is no longer used by consumers or goods in the form of return from partners in the supply chain to be returned to the origin, because the product is unfunctional properly or the function of the item is not needed. Home appliances products within a certain period of time, these products must be replaced because they cannot technically function properly. The process of producing, using, and disposing of electronic products has an impact on the environment of the earth and the universe. If electronic waste is left without a policy to process it, there will be a buildup of electronic waste everywhere and will burden the environment. While this electronic product waste still contains economic value that can still be utilized. Therefore it is necessary to identify electronic waste handling activities, namely those that have material flow characteristics from the customer to the producer (reverse logistics), so as to provide added value
