Abstract

Lighting conditions in office building B of UNISMA have not met the SNI standard because each room has the same number of lights for different rooms; this results in a large amount of electricity consumption from the lighting sector. The installation of the number of lamp armatures should be in accordance with the area of ​​the room and then related to the function of the room and must also meet the standard lighting of the room (SNI 03 – 6575 – 2011.2011). For that, the calculation of the number of lamp armatures is appropriate for the standard and design of room lighting using Dialux software, where the office lighting standard is 350 Lux. Based on these steps, the lighting standard is produced approaching the SNI standard using Philips LED lights. With this design condition, the use of electrical energy becomes optimum and energy efficiency is achieved. Based on the Dialux software simulation, the percentage of savings in the initial conditions and design was 39%:61%.

Abstract

PT. YY, a business organization and an SME (Small to Medium Enterprise), is a distributor of Stick Jelly in FC and NJ branded packaging. Its distribution covers the Greater Malang area, Indonesia. This company often encounters logistical problems, that is delivery delays. Despite having made a delivery target and schedule based on the number of each customer’s requests, its vast marketing area often results in non-punctual delivery time. PT. YY is located too far from its customers, thus, it complicates the daily distribution flow. This study attempts to solve this problem by providing technological support to determine the appropriate location for its buffer warehouse/branch. The Gravity Location Models Approach is used by knowing each customer’s coordinates, the number of requests, and shipping costs. With this approach, the right coordinate point is obtained for establishing a subsidiary branch. Based on the results of calculations and simulations, as well as the location of the buffer, it was found that there was a shipping time saving and an increase in the distribution process efficiency value up to 48%.

Abstract

Hospitals are high-risk workplaces that require a comprehensive Occupational Safety and Health Management System (SMK3RS) to protect healthcare workers, patients, visitors, and the hospital environment. This study aims to analyze the implementation of SMK3RS at Karsa Husada Regional General Hospital, Batu City, East Java, with a focus on hazard identification, risk assessment, and risk control in three priority units: CSSD and Laundry, Hospital Facilities and Infrastructure Management Unit (IPSRS), and the Laboratory and Blood Bank Unit (BDRS). This research employed a case study approach involving 70 workers, with 60 respondents selected through stratified random sampling using the Slovin formula. Data were collected through questionnaires, in-depth interviews, focus group discussions, and document analysis. Instrument reliability was tested using Cronbach’s Alpha (? > 0.70). Hazard and risk analysis were conducted using Job Safety Analysis (JSA), Hazard Identification, Risk Assessment, and Risk Control (HIRARC), and Failure Mode and Effect Analysis (FMEA). The results showed that the Laboratory and BDRS unit had the highest risk exposure, with two activities categorized as extreme risk, while the IPSRS unit had one extreme-risk activity related to working at heights without adequate PPE. Eight failure modes were identified as priority hazards requiring immediate control. Recommended corrective actions were formulated based on the Hierarchy of Controls, including elimination, substitution, engineering controls, administrative controls, and PPE compliance. In conclusion, the implementation of SMK3RS at the hospital still requires strengthening, particularly in high-risk units, to improve occupational safety performance and compliance with Minister of Health Regulation No. 66 of 2016.
