Abstract

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

The Surabaya River plays an important role as water supply of the Surabaya PDAM, irrigation, industry, transportation, and means of recreation. However, domestic, industrial, and agricultural waste that were discharged into the river stream polluted the Surabaya River and decreased the carrying capacity and assimilative capacity. Therefore, effort to monitor and control the Surabaya River water pollution need to be well organized and implemented. The aim of the research is to develop a model of water pollution control on Surabaya River region. The research was carried out based on field survey, in situ and laboratory sample examination, questionnaire, and expert judgment. Pollution control model developed in this study was built into three sub-models, namely: (1) ecology sub-model, (2) social sub-model, and (3) economy sub-model using powersim constructor 2.5 version. Pollution control scenarios were developed using prospective analysis. The results of water pollution parameters such as TSS, DO, BOD, COD, N-NO2, and the level of mercury (Hg) were higher than the allowable class 1 standard. The sources of Surabaya River pollution mainly are domestic and industrial waste with total load of BOD, COD, and TSS are 55.49, 132.58, and 210.13 ton/day, respectively. According to water quality status, the Surabaya River is categorized as heavy polluted and the loading pollution need to be decreased. By using prospective analysis, there were five important factors that affect the future of the Surabaya River water pollution control, i.e.: (1) population growth and community awareness, (2) community perception, (3) implementation of regulations, (4) commitment/local government support, and (5) system and institutional capacity. There are three development scenarios, that are pessimistic, moderate and optimistic. The moderate and optimistic scenario are the realistic scenarios that occur in the future for Surabaya River water pollution control in considering of ecology, social and economy aspects.

Abstract

Rupat Strait is one of small strait in Malacca Strait which located in among coastal of TownDumai area with the Rupat Island in Riau Province. Position of Rupat Strait semi-closed withthe condition of semi-diurnal tide has potency to cause the happening of oil accumulation interritorial water which can generate the damage of ecosystem territorial waters. Strait Rupatown the variety of various type mangrove representing habitat of various fish type and protectthe coast from wave and aberration. Various transportation activity, processing and oildistribution in coastal area of Dumai cause the territorial water of Strait of Rupat gristle to oilcontamination. Lubuk Gaung is a very sensitive regional to oil contamination. Pulau Ketam is asensitive criteria, but region Pelintung is inclusive of middle criteria untill is not sensitivity.

This research aims to determine the sugarcane plants of ratooning productivity with lowexternal input of fertilization treatment towards farmers can increase profits. The method used is the Completely Randomized BlockDesign (CRBD) with four treatments and three repetitions (4x3). Sugarcane varieties R 579 planted in each patch experiment 5x5 m2.Dosage of fertilizer: P0 = 3.6 kg/year plot experiment was 100% dosage usage of chemical fertilizers used by farmers. Further dosageswere P1 (75%) = 2.7 kg/plot, P2 (50%) = 1.8 kg/plot and P3 (0.25%) = 0.9 kg/plot, each supplemented with fertilizer 5 mL of liquidorganic/patch a year. Sugarcane crops with a variety of treatment showed no significant difference. The highest productivity wasachieved at dosages of P2 (50% chemical fertilizers plus organic fertilizer) is 21.67 kg per square meter. Chemical fertilizers can besaved 7 quintals per hectare a year or Rp 997,500 per year. Additional costs of liquid organic fertilizer Rp. 100,000 per hectare year andlabor Rp 100,000 per hectare, so the additional advantage of saving farmers fertilizer Rp. 797,500 per year.Key words: sugarcane plant, ratooning, fertilizing, profits.

Abstract

Water quality in Maninjau Lake has been thereatened by organic and inorganicmatters that are flown into the lake. The pollution sources arc many activitiesaround the lake such as residential area, husbandry, agriculture, an fish culture onthe lake (floating net cage). These activities result in huge pollution laods and thetrends are predicted to increase. Understending on the pollution loads, polluitonsources and asssimilativc capacity are important in formulating pollution controltechniques in lake waters. The objectives of the research was to determine level ofpollution waters of Maninjau Lake. The results of this research showed thatpollution load parameter susch as Total Suspended Solid (TSS), ChemicalOxygen Demand (COD), Biochemical Oxygen Demand (BOD) and TotalPhosphorus were very high. All parameters of pollution loads have ciceded itsasssimilative capacity. The level of pollution in the study site is classified asmedium category.

Abstract

ABSTRACT The Government of Indonesia has developed groundwater irrigation schemes in some province e.g. East Java, Central Java, Yogyakarta, Wast Java, Bali, West Nusa Tenggara and East Nusa Tenggara. However, not all regions were able to optimally utilize it. The irrigation effeciency of groundwater irrigation scheme was about 59%, whe;; the wells-pumping efficiencies were varied from 28 to 98 %. In thefuture, the irrigation effieciency should be increased to anticipate water deficit during dry season. The application of trickle irrigation in indonesia has not been widely developed. Although trickle system has been used, however, it is still limited for few commercial agribusinesses. Trickle irrigation systems have a prospect to be developed in some regions having limited water resources. For preliminary stage, the systems could be applied in groundwater irrigation schemes that have been developed either by farmers or government. Keywords: irrigation effieciency, trickle irrigation, groundwater irrigation schemes
