Abstract

ABSTRAK Penanganan kelangkaan sumberdaya air dapat didekati melalui dua sisi, penawaran dan permintaan. Penelitian ini difokuskan pada upaya menangani kelangkaan sumberdaya air melalui sisi permintaan. Upaya penekanan permintaan memerlukan informasi prilaku konsumen terhadap variabel penentu permintaan air, baik permintaan air (langsung) maupun permintaan air maya/virtual water (air yang digunakan untuk menghasilkan barang dan jasa yang dikonsumsi oleh masyarakat). Secara khusus penelitian ini bertujuan untuk: (1) mengestimasi fungsi permintaan air langsung dan air maya (2) menganalisis elastisitas permintaan air dan (3) menganalisis kebutuhan air dan air maya masyarakat Pulau Lombok. Hasil penelitian menunjukkan bahwa permintaan air pada level rumahtangga secara signifikan dipengaruhi oleh harga, jumlah anggota rumahtangga (kecuali permintaan air minum kemasan) dan pendapatan (kecuali permintaan air sumur). Seperti harapan, harga berpengaruh negatif terhadap jumlah air yang diminta/dikonsumsi pada seluruh jenis permintaan air, sedang pendapatan, jumlah anggota rumahtangga, dan pendidikan berpengaruh positif kecuali pendidikan berpengaruh negatif pada permintaan air sumur. Permintaan air minum kemasan memiliki elastisitas harga tertinggi (-5,22), diikuti air PDAM (-0,66) dan air sumur (-0,24). Seperti halnya pada permintaan air, permintaan air maya pada level rumahtangga juga dipengaruhi secara negatif oleh harga barang tersebut. Elastisitas harga permintaan air untuk menghasilkan barang dan jasa yang dikonsumsi oleh rumahtangga seluruhnya bersifat elastis, kecuali permintaan air untuk tahu dan tempe. Permintaan telur paling elastis terhadap harga (-6,6), kemudian berikutnya berturut-turut adalah permintaan ikan air tawar (-2,82), kedelai (-2,29), daging sapi (-2,52), beras (-2,05), kacang tanah (-1,29), dan jagung (-1,23). Untuk memenuhi kebutuhan air minum dan air bersih serta kebutuhan pangan masyarakat Pulau Lombok diperlukan air sebesar 2.622.092.101,44 m3, yang terdiri dari air langsung yang bersumber dari air PDAM sebesar 6,79 m3/kapita/bulan, air sumur 6,24 m3/kapita/bulan, air minum kemasan 10,18 liter/kapita/bulan, dan air maya sebesar 48,6 m3/kapita/bulan. ABSTRACT Water scarcity can be addressed by managing both supply and demand side. In general this research was designed to study the consumer behavior toward variables determined water dan virtual water demand. Specifically this research was aimed to (1) estimate water and virtual water demand function, (2) estimater their elasticities, and (3) analyze water and virtual water consumption. The results show that water demand at household level significantly affected by its own price, the number of family member (except for bottle water demand), and income (except for pumping water demand). As expected. Water price affect negatively for all water demand, while income, the number of family member, and level of education (except for pumping water) affect positively. Bottle water demand has the highest price demand elasticity, reach up to -5.22 compare to PDAM water demand (-0.66) and pumping water demand (-0.24). Virtual water demand was also negatively affcted by their own price of several commodities consumed. Virtual water demand for all comodities are considered elastic, except for tofu and tempe demand. Virtual water for producing egg was considered the most elastic (-6.6), followed by virtual water demand for producing fresh water fish (-2.82), soybean (-2.29), meet (-2.52), rice (-2.05) peanuts (-1.29) and corn (-1.23). Total water consumption of Lombok reached up to 2.622 million/ month, consisted of 6.79 m3/capita/month of PDAM water, 6.24 m3/capita/ month of pumping water, 10.18 liter/capita/month of bottle water and 48.6 m3/ capita/month of virtual water.

Abstract

ABSTRACT The aim of this study were to: (1) analyze the determinants of housewife participation in spring water protection movement (well-known as PERMATA, Perlindunganmata air); (2) assess the alternatives for increasing awareness and participation of housewives in the movement; and (3) design a model of and strategies for spring protection and conservation in ways that are participatory and sustainable the forest area of Rinjani in Central Lombok.The research was conducted in Forest Area of Rinjani in Central Lombok, i.e. in the districtsof BatukliangUtara and Kopang. The collection of data and information is done through the approach/technique of in-depth interviews, focus group discussions (FGD) and direct observation. The results showed that the determining factors in the lack of participation of housewives in the movement are: (1) lack of socialization the PERMATA program, (2) lack of economic incentives, (3) no regulations governing the involvement of housewives, and (4) no involvement of housewives in conservation planning. Alternativesfor increasing participation can be done through: (1) awareness improvement (2) provision of the exemplary and directions from role models, and (3) campaigns and publications of PERMATA movement. The most likely model of and strategies for spring protection and conservation in participatory and sustainable way is the housewife economic empowerment, among others through the development of family forest, small business development in NTFPs, and the development of compensation conservation.

Abstract

abstrak Water service providers are often under pressure to improve the service quality without having expertise necessary to understand how valuable this improvement would be to their consumers. Moreover criticisms also arise since many master plans of water treatment technologies and their distribution systems are mostly engeneer-dominated supply side approach and neglect demographic and financial realities of their consumers. The long term goal of this research is to find a healthy and safe water supply management system so that water can be used to drink directly from the tap. Besides this long term goal, this research also have specially short term targets namely: (1) to estimate the consumers’ willingness to pay (WTP) for water quality improvement; (2) to indentify factors determining the WTP, and; (3) as a respond to the issue of safe dringking water from consumer’s side in the City of Mataram dan West Lombok Regency. Research was conducted by utilizing Contingent Valuation Method (CVM) by interviewing 600 respondents selected through stratified random sampling. Results concluded that: Households’ willingness to pay for the quality improvement of water service is 7,233 rupiah per month so that total WTP in 2007 is 4.7 billion rupiah. Five main factors, among others, that determine WTP are: Consumers’ perception on contaminants in their drinking water Gender, tariffs cateory access to other drinking water sources respondents’ education The financial sustainability of quality improvement program of drinking water requires an appropriate tariff level, more than that it can guarantee a high collection rate. It is therefore urgently needed a proper justification from both supply side and beneficiaries (demand side). WTP estimation produced by CVM can be seen as an important information from demand side. Although consumers’ WTP is relatively high, their low income per capita should be considered in setting a suitable tariff level.

Abstract

Abstact As an exportable goods, shrimp price was highly determined by international market and exchange rate of domestic currency. Therefore the devaluation of rupiah was expected to be a favorable condition for shrimp culture as indicated by the rise of shrimp production and productivity in 1998. However, it turn back to decline along with the strenghtening of rupiah and international protection policies imposed by importing countries in 2004. In addition, the escalation of regional laws (Perdas) issued at the provincial or district level might increased production costs and local tax, and therefore has decreased profit. The question then, is production of cultured shrimp within unfavorable domestic environment and protectionist international policies still profitable? What policies should be imposed to induce shrimp culture production efficiency, profitability and competitiveness? The objectives of the study were to evaluate shrimp culture profitability, and simulate such policies favorable for the development of shrimp culture. Research was conducted by survey and literature review, while analysis was carried out by applying Policy Analysis Matrix (PAM). The strong point of this technique is its ability to provide information on policy impacts on farm level profits. Stochastic frontier productivity function (SFPF) model was employed to simulate the impact of several policies. The results showed that based on private prices, shrimp culture in Dompu district still profitable, however, analysis based on social prices the traditional system indicated negative profit. Intensive system produced 1,121.67 kg/ha or Rp 8,089,796 profit, while the traditional one generated only 123.60 ka/ha or Rp 1,661,659 profit. The government therefore was recommended to promote the intensive system after conducting risk assessment both domestic (security, pests, and diseases) and international (health, environmental, and trade policy issues). In addition to this the enforcing law and order is also critical to eliminate fear over uncertainty. The policy simulations indicated that imposing 100 % of technical efficiency is the most favorable policy for semi intensive and intensive shrimp culture, while price and exchange rate policies more favorable for the traditional one.
