Abstract

The occupational safety and health (K3) conditions of companies in Indonesia are estimated to be quite low, this can be seen from the high risk of accidents that can occur in a company. Work accidents occur due to workers, work tools and the work environment, so it is necessary to implement occupational safety and health (K3) in carrying out mining activities. Safety and health factors are very important because they have a big influence on employees, society and also company assets. The aim of this research is to look at the implementation of Occupational Health and Safety in coal transportation at PT Lematang Coal Lestari. The method used in this research was field observation in the form of visits and direct field observations as well as data collection in the form of interviews or surveys. The research results showed that from the 8 questionnaire questions given to 5 respondents, PT Lematang Coal Lestari (LCL) employees received very good responses. Keywords: Occupational Health and Safety, Transportation, Coal.

Abstract

The design development of the Gudang house for drought adaptation can include a rainwater harvesting system on the roof. The purpose of this study was to develop and test the success of a rainwater harvesting design and irrigation system in a Gudang house to meet domestic water supply and small-scale agriculture in drought adaptation. The stages of the research were divided into climate data studies, analysis of domestic water needs and small-scale agriculture, integration of rainwater harvesting and small-scale agriculture designs in the Gudang house, and simulation of water flow fluids in the rainwater harvesting system and planting media. The results of the study showed that the design of the irrigation system in the planting media was able to irrigate plants for up to 7.06 days. The probability of rainfall with a return period of 2 years (Rprob with T=2 years) and the average catchment discharge of rainwater harvesting for all zones is 47.14 m3/month. This discharge was sufficient to meet the domestic water supply and small-scale agriculture at the Gudang house, and the material was still sufficient to meet the water supply for one more house. The simulated discharge at the outlet of storage tank 1 was 1.236 × 10-5 m3/s, whereas the outlet discharge of storage tank 2 was 1.734 × 10-5 m3/s, indicating that storage 2 was filled faster than storage 1. However, with the designed system, Storage 1 and 2 are connected to each other through pipes so that their capacities will be filled equally. The innovation of rainwater harvesting systems and integrated small-scale agricultural systems in the Gudang house can be a promising solution for future drought adaptation.
