Abstract

ABSTRACT A warranty is an agreement between a manufacturer and a consumer that guarantees the quality of a product for a certain period or period of use. There is a warranty, products that are defective before the warranty period expires will be replaced or repaired by the manufacturer. From the consumer's perspective, a warranty serves as a guarantee of protection against a product failing or not performing as expected and also as a provider of information about the quality of the product. From the manufacturer's perspective, warranties provide benefits by protecting the manufacturer from excessive consumer complaints. This study aims to determine the estimated warranty costs for “X” brand truck products sold by PT ABC using the best time scale method. The policy implemented by the company is a two-way warranty policy, specifically a warranty policy for automobile products for a period of 3 years or 100,000 km, whichever comes first. The purpose of this study is to perform estimates for branded heavy goods vehicles. The estimated parameters of the truck damage model were obtained using the maximum likelihood method. With the Golden Section algorithm, the resulting parameter is ∈0 = 0.35125 with a minimum variance coefficient obtained of 0.7427391 and a guarantee limit at L= 5.4588. The K distribution of the best fitting time scale is an exponential distribution with parameter λ = 0.964902. The estimated warranty cost for truck brand “X” in company “ABC” using the best time scale method produces a cost of IDR 958,949,134. Keywords: 1 Dimension Guarantee, Best Time Scale, Maksimum Likelihood Estimation.

Abstract

COVID-19 has spread rapidly in places where people interact socially, with aerosol transmission being a significant concern, especially in enclosed spaces where infected individuals spend extended periods with others in crowded and poorly ventilated conditions. The use of masks is a preventive measure against the spread of the virus that causes COVID-19. Concerns have been raised that carbon dioxide may accumulate in masks over time, potentially leading to respiratory issues and other problems such as impaired concentration at work. This research aims to conduct an experiment to study concentration based on the physical work environment, including factors such as room temperature, Body Mass Index (BMI), duration of mask use, and age. Concentration will be measured through reaction time, which includes visual, auditory, and motor components, using a factorial design method. The results of the study indicate a significant relationship between the concentration, represented by the reaction time of the respondents, and several factors: temperature, BMI, age of the respondents, and type of reaction (visual, auditory, and motor). Based on factorial analysis, it can be concluded that temperature, age, BMI, and type of reaction all influence reaction time at a significance level of 5%.

Abstract

Sampah adalah buangan yang dihasilkan dari suatu proses produksi baik domestik (rumah tangga) maupun industri. Permasalahan sampah yang terjadi saat ini banyak diakibatkan oleh kegiatan produksi dan konsumsi yang dilakukan oleh manusia. Aktivitas yang dapat dilakukan untuk meminimalisir permasalahan sampah adalah dengan melakukan pengelolaan sampah sejak dari sumbernya. Pengelolaan sampah yang tidak baik dapat berdampak bagi manusia dan lingkungan yaitu bisa menyebabkan di antaranya kerusakan ekologis, menyebabkan penyakit, menyebabkan terjadinya banjir, menyebabkan bau tidak sedap/bau busuk, dan menyebabkan terganggunya estetik suatu daerah. Penerapan konsep 3R (reduce, reuse, dan recycle) dapat mengurangi volume sampah dan memberikan nilai tambah bagi masyarakat. Sampah organik dapat dikumpulkan dan diolah menjadi pupuk kompos, pakan ternak, hingga menjadi biogas, sedangkan sampah non organik dapat didaur ulang atau dijadikan bahan untuk kerajinan. Masih banyak masyarakat yang belum memahami pengelolaan sampah dengan baik salah satunya adalah masyarakat Kelurahan Kebon Kangkung. Oleh sebab itu, kegiatan pengabdian masyarakat ini adalah dengan melakukan sosialisasi dan edukasi kepada masyarakat guna memberikan pemahaman untuk mengelola dan mengolah sampah dengan baik terutama untuk sampah rumah tangga.

Abstract

Lot sizing techniques have been widely analyzed by experts, because ordering costs, storage costs, and lot sizes have a significant impact on the total cost of ordering. This study uses lot sizing techniques including Wagner-Whitin algorithm, Silver-Meal algorithm, Least Unit Cost, Least Total Cost, Part Period Balancing, Period Order Quantity, Groff algorithm, and Lot for Lot. The data used is taken from a chemical raw material procurement company, including ordering and storage costs. The initial analysis concluded that the Silver-Meal algorithm and the Groff algorithm have relative biases that are close to the Wagner-Whitin algorithm. The second analysis concluded that for the lot sizing technique, the calculated F value (84.3) was greater than the F table value (2.1), indicating a significant effect of the lot sizing technique on the relative bias percentage. Furthermore, the demand analysis shows that the calculated F value (80.0) is greater than the F table value (2.6), indicating a significant influence of the demand on the percentage relative bias
