Rice Supply Patterns in Kalimantan Selatan: Part of solution for regional food security
Full text linkSouth 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

Voltage Profile Improvement through Load Shedding Action Using Linear Programming-based Optimal Power Flow
Full text linkThis paper proposes a load shedding scheme to improve voltage profile of a power system. A linear programming approach to optimal power flow is utilized to obtain optimum amount of load to shed in order to bring power system to an acceptable operating region. In this work, ±5% voltage variation is considered to be acceptable and hence, an immediate control action should be taken if power system is operated beyond this limit. The proposed method was tested on the IEEE 57-bus test system. Results showed that the proposed approach was able to provide a minimum amount of load shedding action to improve voltage profile of the studied power system
