Abstract

The computerized system is closely related to today’s office works. Computer works with high intensity of repetition and awkward posture can cause harm or risk. This can cause discomfort in several areas of the body. Therefore, an office ergonomics assessment that focuses on humans as the most important component is needed to determine the impact and causes of the discomfort problem. In this study, MIRTH Office is used as the assessment tools. The questionnaire consists of two parts, namely general information and conformity assessment. The data processing stage in this study consisted of problem identification and problem grouping. The results showed that most of the respondents experienced pain in the neck, shoulders, elbows, wrists and lower back. These results indicate the need of ergonomics intervention as early as possible to prevent the risk of musculoskeletal disorders.

Abstract

In a warehouse facility layout design including a health clinic, the layout design of warehouse facilities and production storage areas plays a very important role, it is impossible for the manufactured goods to be distributed directly to all customers. For this reason, there is a need for a good storage area and storage system to simplify the production process. Clinic XYZ is a 24-hour public health clinic, located in a sub-district in North Sumatra, to be precise in Medan Deli District. The problem that occurs is the random arrangement of goods in the warehouse without paying attention to storage and arrangement patterns that depend on the position of the empty warehouse. Based on observations, it is known that the time span needed to look for drugs at the clinic is too long, so this will make it difficult for employees / operators to manage the products to be stored or retrieved from the drug warehouse. One of the warehouse design methods that can be used is the dedicated storage method. Dedicated storage is a method of placing a specific location or storage area for each item stored. In this study, the types of drugs were classified into drugs, solid types of drugs, semi-solid drugs, liquid drugs and gas drugs. Based on the results obtained, the number of slots needed in the drug product warehouse is 11 slots, the total floor area needed is 13.2 m2, the area needed for storing medicinal products with an alley area is 6.8 m2, the percentage of area that is not used for storage the product in the medicinal product warehouse is 34% and the diagonal length of the hand truck when carrying the box is 1.56 m.

Abstract

The oil palm is the most productive plantation product in Indonesia. Government strategies and policies related to oil palm plantations continue to be carried out considering that the plantation area is increasing every year. Segmentation of oil palm plantations based on area, production, and productivity aims to identify groups of potential oil palm plantations in the territory of Indonesia. This segmentation can provide consideration in formulating strategies and policies that will be made by the government. The segmentation method for grouping oil palm plantations uses the K-Means Clustering Data Mining technique with 3 clusters specified. Data mining stages start from data collection until representation is carried out, where 34 data sets are collected, only 25 data sets can be processed further. The results of this grouping obtained three plantation segments, namely 72% of the plantation group with low potential, 20% of the plantation group with medium potential, and 8% of the plantation group with high potential.
