Batam is one of cities whose industry has been developing so fast in which its island is located strategically. The development of Batam Island as an industrial area has pushed ahead the development of other sectors. As the industrial sectors have developed in Batam city, the residential areas for the workers have also developed quickly outside the industrial areas, Batam. The mushrooming of houses for workers who want to rent outside the industrial areas has caused a new problem for Batam, in which the quality of environment is getting low; furthermore, this tends cause slum. This is because a lot number of workers there are from other areas outside Batam. Moreover, this is also caused by the increase of employment composition in industrial sector of 53,03%. The aims of this research were to know the condition of the whole aspects - social, economy, and ecology in the future and to observe a sensitive driving system to determine the sustainability management of housing. This research was carried out in an industrial areas in Batam city including Muka Kuning, Tanjung Uncang and Tembesi. This research was performed in five months from May to September 2015. The modeling of development and housing which is sustainable in Batam Industria Areas was done with the approach of dynamic system. The result of simulation showed that the quality of environment in 2010 was 44.85% and will decrease of 34.62% in 2020. This was due to the increase of waste which could not be managed. The level of security and comfort to live in the housing in 2010 was 68.28% and will decrease of 48.43% in 2020. With all of the problems mentioned, the level of housing sustainability in 2010 was 42.33% and will decline of 29.58% in 2030. The process to develop the housing is still needed because there are still many people whose income is still low and they need the housing. The main strategy to develop and use the housing needs cooperation partnership or the relationship among the government, the manager of housing and the residents. Therefore, the development that will be done in the future will be better. Keywords : housing, environment, dynamic system, simulation

Abstract ECR is one of Maintenance Performance Index (MPI)’s criteria in The System of Eco Maintenance (SEM) proposed for sugarcane fabrication. The SEM is a maintenance system that concerns to energy conservation issue in sugarcane fabrication. Reduction of energy consumption can affect the reduction of pollutant produced by sugarcane fabrication process. MPI and EPI (Environment Performance Index) are Operational Performance Index (OPI)’s components that calculated by SEM. The OPI will be used for selecting a proper strategy for revitalization of sugarcane factory. ECR uses a pairwise comparison assesment based on experts interview and judgement. Then, it will be calculated by Expert Choice software. The weight of ECR’s criteria will be multiplied by criteria value from data processing result in SEM software. The results show that the highest value of ECR is of 41.52 for Mill and Boiler station and the lowest result is of 8.83 for Drying and Packaging station. Finally the value of ECR will be classified into very critical (ECR1), critical (ECR2), less critical (ECR3) and non critical (ECR4), to determine the level of station’s criticality. keywords: ECR, eco maintenance, sugarcaneAbstrak ECR adalah salah satu dari kriteria Indeks Kinerja Perawatan (MPI) dalam Sistem Eco Maintenance (SEM) yang diusulkan untuk pengolahan gula tebu.

ABSTRACT This paper presents the improvement of block system planning of irrigation water in cikarang area for optimization of the irrigation water distribution by using Genetic Algorithm. A genotype representation of spatial allocation was proposed: a fixed-length genotype composed of four genes that represent spatial allocation determined by greedy algorithm. The process of optimizing genotype includes evaluation, selection, crossover, and mutation,. Evaluation process determined the fitness of the genotype based on the distance of water sources, availability of irrigation water, labor, mechines and delay of harvesting opertion of last-season crop. Several types of selection, crossover and mutation were tested to obtain the best processing sequence for optimizing the genotype. This approach was comared to a real block system problem determined by Perum Jasa Tirta II and the adventages of the approach were identified. Keyword: representasi, Algoritma Genetik, Irigasi
