Abstract

PT. XYZ is a company engaged in contracting for infrastructure development. In the process of infrastructure development, it is inseparable from the risk of work accidents. Based on the results of observations in the field, the potential for work accidents was found. This study aims to analyze potential hazards and provide improvement proposals to minimize the risk of work accidents in the Lombok Peaker PLTMGU Jetty Construction Project. The method used is HIRARC. HIRARC is used to identify the risk of work accidents as well as analyze hazards and provide improvement proposals to minimize existing risks. The results of the study were identified and there were 8 potential hazards in the construction of the Lombok Peaker PLTMGU jetty construction project, namely 25% potential hazards with low risk levels, 37% potential hazards with high risk levels and 38% potential hazards with extreme risk levels. Improvement proposals that can be given in the Lombok Peaker PLTMGU jetty construction project based on the K3 control hierarchy such as soil erosion around the temporary jetty area, standing under the process of material lifting by cranes and stacking steel pipes by eliminating to eliminate activities in the erosion area. This research is expected to minimize the risk of work accidents in the construction of the Lombok Peaker PLTMGU jetty construction project.

Abstract

PT. XYZ is a company engaged in seaweed processing, where the production process uses coal as boiler fuel to generate steam power for driving production activities. Coal combustion produces two types of waste, namely Fly ash and Bottom ash. Long-term accumulation of Fly ash and Bottom ash waste may require large storage space and cause environmental problems. This study aims to utilize Fly ash and Bottom ash waste (FABA) as an additive material in the production of concrete blocks (batako) and to calculate the production cost per batch. The research method used to address the problem was an experimental method. Based on the test results of the concrete blocks, it can be concluded that Fly ash and Bottom ash waste is feasible to be used as a mixture material in concrete block production with quality level II, using a composition of 300 g cement, 1500 g sand, and 1500 g Bottom ash. The test results showed a unit weight of 2.5 kg/unit, a compressive strength of 60 kN, and a water absorption percentage of 30%. The total production cost for producing concrete blocks using Fly ash and Bottom ash waste was Rp. 1,057,808 per batch, or Rp. 3,340 per unit

Abstract

Marketing strategy is a policy implemented by a company to win competition within an industry. By determining the right marketing strategy, a company can achieve a competitive advantage over its rivals. PT. X is a producer of bottled drinking water (AMDK) in South Sulawesi. PT. X aims to determine an effective marketing strategy for their company to compete with other brands and increase profitability. This research utilizes the Quantitative Strategic Planning Matrix (QSPM) to determine which strategic alternative is the most attractive or appropriate for PT. X, based on the analysis of influencing external and internal factors. The data source used consists of respondent answers from questionnaires distributed to the marketing manager of PT. X. The data analysis technique follows the analytical steps of the QSPM to select strategic alternatives. The results indicate that the strategic alternative for marketing PT. X's bottled water products is to enhance and expand sales access through social media, with a Total Attractiveness Score (TAS) of 0.789
