Abstract

The number of aquaculture households in Palembang City continues to increase from 2017 only 682 households to 1,050 households in 2018. But on the contrary in terms of the amount of aquaculture production, the total production decreased by 24,259 tons in 2014 and only 20,327 tons in 2017 (BPS, 2018). One of the steps that can be taken to determine the condition of aquaculture in Palembang is by doing forecasting. This is useful for knowing or predicting the results of aquaculture production with precise accuracy. This study aims to determine the prediction of aquaculture production in Palembang City using the Autoregressive Integrated Moving Average (ARIMA) method. The results of the ACF and PACF plots show that both plots have a tail off pattern. the predictive model obtained is ARIMA (1,0,1) but after over fitting the model, the ARIMA model (2,0,1) is the best model because it has the smallest MAPE value, which is 48,30. Based on the ARIMA model (2,0.1), the forecast values for aquaculture production in Palembang City from 2021 to 2030 are 19542,598 tons, 12846,331 tons, 50682,093 tons, 43389,831 tons, 15352,492 tons. , 9595,313 tons, 26140,949 tons, 36258,543 tons, 29041,898 tons, and 19548.050 tons

Abstract

Safety is a program made to the workers as well as employers attempt to prevent accidents by means of recognizing things that could potentially cause accidents as well as anticipatory action in case of accidents. The goal is to create a safe workplace so it can hit the lowest possible risk of accident. Formulated the problem in this research is a work accident prevention efforts while unloading at the MV.Portlink. The research was carried out during the period of sea practices 9 months on the ship where the author undertakes the work practices of the sea. The theory used in this research is the theory- theory, human resources management with regard to safety. The method carried out intensively, researchers participating in the long field. This type of research is qualitative, descriptive. Method of data collection is done by observation, interviews and literature study. Methods of data analysis used the assortment (triangulation), and continuously until it is saturated. From the results of this research should be known throughout a worker follows the safety training work done by the company and penggunanaan self protective tools should be an obligation for workers at the port so that all workers can avoid a fatal accident due to work.
