Abstract

South Kalimantan is a largest rice producer in Kalimantan island. More than five years its rice met by their own production, moreover it has supplied to other area such as Kalimantan Tengah, Kalimantan Timur and Kalimantan Utara. In many studies, rice stocks play a critical role in determining the regional’s food security. In recent issues, rice stocks has a wide impact on an array of economic, political, societal stabilities. Unfortunately, most of the land in Kalimantan Selatan is classified as wetlands, where the land productivity is low. Therefore, this study analyzes rice supply patterns in Kalimantan Selatan in order to provide policies development toward rice self-sufficiency. This research is using system dynamics approach to explore the system which then develop any alternatives of rice policies. Eventually, this study provides evidences for the need to consider rice supply system in the regional’s food security policies.

Abstract

Fresh fruit bunches (FFB) are mostly harvested manually in large and small plantations. Ergonomically, this type of work has the potential to cause permanent muscle injuries over time. Based on these concerns, a study was conducted to assess the workload by monitoring heart rates using a Heart Rate Monitor for each task element of the oil palm fruit harvesters. The risk level of these harvesters was also assessed using the Rapid Entire Body Assessment (REBA) method. The risk levels were evaluated based on the weight and height of harvesters. The analysis of the harvesters' workload, based on heart rate measurements during different harvesting activities, shows that cutting bunches and fronds falls into the heavy workload category. Moving between locations is classified as a moderately heavy workload, while unloading and organizing bunches at the collection site (TPH) is considered a light workload. The results of the risk level analysis for the harvesters show that for the minimum weight variable, the risk is in the moderate risk category, while for the maximum weight variable, the risk is classified as high. In terms of height, both the minimum and maximum height variables fall into the moderate risk category. Keywords: Ergonomics, Oil palm harvesters, Rapid entire body assessment, Risk level, Workload.
