Abstract

Every manufacturing company faces safety risks in its production process. OHSAS 18001:2007 certification is required by international companies for ensuring that they have good safety and health management. The purpose of this research is to identify, assess, and define mitigation for safety risk in PT Pindad (Persero) – Munition Division’s Appliance Sub-Department based on OHSAS 18001:2007. The result shows that the safety risk factors in Appliance Sub-Departments are electricity shock, tools graze, tools cut, sprained limb, tools crush, dust and grindstone fragments, and cutting oil burst. Those risks happen because of human behavior, infrastructure, and working tool factors as shown in fishbone diagram. Most safety risks are included in low risk category and can be handled through administrative controls and personal protective equipment (PPE) usage. Some safety risks are included in medium risk category and need to be handled through engineering control and PPE usage.

Abstract

This research was conducted to analyze the comparison of theresults of the trading on the currency pair USD/JPY one hourafter Non Farm Payroll’s release time using fundamentalanalysis, Stochastic Oscillator technical analysis, ADXtechnical analysis, and combination of technical analysisduring the period January 2015 to November 2016. Samplingtechnique used was the comparative analysis put forward bythe Nazir (2005) where the purpose of the comparativeanalysis is to compare between the two groups in one or morevariables. The research results showed that fundamentalanalysis has the return (in pips) which is the highest amongthe four others analysis. In the technical category, StochasticOscillator technical analysis has the highest number (in pips)of return than ADX technical analysis as well as combinationof technical analysis.

Abstract

Chicken egg production at PT. Pulau Mandiri Jaya Farm for the 2021-2024 period showed significant monthly fluctuations (2,140-6,890 tons) due to seasonal patterns and feed management challenges, requiring accurate time series forecasting for optimal planning. This study aims to predict egg production using the SARIMA(1,1,1)(1,1,1,12) model to capture annual seasonality. This quantitative descriptive study analyzed monthly univariate data from 48 observations, with purposive sampling (80% training: 38 months; 20% testing: 10 months). Data analysis used Python statsmodels for stationarity testing, ACF/PACF identification, model fitting, and MSE evaluation. The results showed excellent model performance (MSE=0.3262; Ljung-Box p=0.44; Jarque-Bera p=0.65), accurately predicting 2025 production (3,886-6,873 tons). In conclusion, the SARIMA model enables precision feed stock planning (60-70% of production costs), improving operational efficiency and food security in South Sumatra.
