Abstract

Degradation and critical condition of watersheds in Java is showed by the damage of environmental condition, such as vegetation covered area that is less than 20%, big fluctuation of the river debit, frequent floods, land sliding and draught that its frequency is increased every year. These all result in the decrease of water resource capacity in Java. Besides, Java, that is only 7% of the area of Indonesia, has the highest population amongst islands in Indonesia and supplies the largest Indonesian economy (60%), needs continuously increase water resource capacity. Efforts to manage water resource through watershed environment rehabilitation, using functional approach (organizational roles) or structural approach likes physical/building rehabilitation is crucial to be carried out especially for the very critical watershed.

Abstract

Coastal area is one of the marginal areas that is not suitable for agriculture field. However, bad quality of the area can be improved physically and chemically by adding some organic matters into the soil. Another factor that also plays an important role in improving the quality of sandy soil is weather, which consists of sun radiation, temperature, humidity, soil temperature, wind flow and rain fall. In order to obtain a good quality micro weather in a chili vegetation field, a cover may be placed above the vegetation to create a warm and wet micro weather which will free the vegetation from stress. Another important thing to attain success in productive agriculture is a certainty to get water or irrigation that can be engineered. Through those environmental engineering, an improvement on chili harvesting product has been achieved at Glagah Coast, West Progo, Yogyakarta.

Abstract

Peningkatan pertumbuhan penduduk dan ekonomi di kota-kota besar tentunya diiringi dengan peningkatan kegiatannya.Pada titik tertentu akhirnya akan menimbulkan berbagai masalah perkotaan, seperti ketidakseimbangan suplai dankebutuhan lahan, pencemaran, banjir, kemacetan, dan konflik masyarakat. Upaya mengatasi timbulnya permasalahan,salah satunya dengan pembangunan kota baru. Pembangunan kota baru di Indonesia telah menjadi isu utama dan sudahditerapkan. Namun yang terjadi perkembangan kota baru belum sepenuhnya menunjukkan hasil yang menggembirakan,karena yang terjadi adalah sebagian besar hanya memindahkan permasalahan yang ada dari kota-kota besar ke kota-kotabaru, baik masalah fisik maupun sosial ekonomi. Sebagai salah satu contoh adalah Kota Tangerang Selatan, dimana kotaini masih berorientasi pada pengembangan aspek ekonomi saja. Penelitian ini bertujuan untuk menyusun arahan kebijakanpengembangan kota berkelanjutan, suatu model kebijakan yang mengharmonisasikan tatanan ekonomi, tatanan ekologis,dan tatanan sosial untuk mewujudkan pengembangan kota yang berkelanjutan. Pendekatan yang digunakan adalah sistemdinamis. Sistem dinamis adalah suatu metodologi untuk mengelola sistem-sistem umpan balik yang kompleks denganmempertimbangkan faktor waktu. Hasil simulasi dari beberapa skenario, maka terpilih skenario yang mengimbangkanantar aspek pembangunan berkelanjutan dan mempertimbangkan kondisi nyata di lapangan sebagai skenario prioritas.

Abstract

Water resource capacity in Java is significantly decreased. This has beennoticed by the more frequent floods and over-dried seasons happened inseveral locations in Java. On the other side, the water demand in Java israised as the result of increasing population and quality of live. Reducingof water resourcing capacity related with forest degradation, change ofland usage and river pollution. Interpretation of the satellite imaging in2005 showed that the vegetated land areas is left abaut 2,4 acre or 21%of the wholw area of Java island. This is lower than the regulatedrequirement, i.e. about 30%. Efforts might be needed to solve thisproblems, cover (1) Regulation of the number and distribution of population;(2) Forest and land rehabilitation; (3) Coasts degradation control; (4)Increasing efficiency of water usage and control of river pollution; (5)Management of land usage by implementing the required 30% area asopened green areas; and (6) Deregulation of the water managementinstitution.

Abstract

Productivity is a ratio between an output and another input, such as: labor,and land. To solve the problem of resource limitation, it is necessary todevelop some approaches, such as priority commodity approach and priorityterritory development approach. Some factors influencing the problem ofnon optimal development are very low development of Iceal prioritycommodity and undevelopment of priority area. Several policies andstrategies that are needed in order to increase an area productivity is through priority sector / commodity development which is adjusted with carrying capacity of adjacent area, labor mobilization and human resourcedevelopment. In order to support the direction of those policy and strategy,some programs that are developed are: reorientation program of localeconomic development that based on priority commodity, developmentprogram of strategic area and human resources development, quantitycallyand qualitycally. In order to get a huge output to increase the people welfare, it is necessary to choose a right local priority commodity, thus others priority sectors will also be developed.

Abstract

ABSTRACTResearch on modeling and hydrological services in forest and watershed (DAS) ecosystem protection is still very little done in Indonesia; therefore, this research will be very useful for related stakeholders, since the purpose of the research will answer two problems, namely:  (1) what factors can significantly affect the hydrological services in the protection of forest and watershed ecosystem both in the upstream and downstream areas DAS and (2) establish the economic value of hydrological services in upstream and downstream watershed areas. The results of the study indicate that: water consumption in the downstream area is strongly influenced by: (a) family expenditure at 96.5% significance level, (b) family income at 80.7% significance level, and (c) work experience at significance level 72.4% with R Square Model 53.00% validation test. Water consumption in the upstream area is influenced by: (a) the cost of water storage at the significance level of 94.4%, (b) the age of the respondent at the significance level of 71.4%, and (c) the distance to the resource (location water springs) water at a significance level of 55.7% with a validation test of R Square model 97.30%. The research in this study at the same time responds to the existence of hydrological services as a model of protection of forest ecosystems and integrated and comprehensive watersheds from upstream - downstream; economic value of ecosystem services in forest and watershed protection in the form of hydrological services, which is the value of choice from the utilization of water resources or as hydrological services, which is Rp. 1.272.211.617.235. The value of this choice is basically the sum of the Consumer Surplus in the downstream area of Rp. 830,837,758,433 and the value of Producers Surplus in the upstream area of Rp. 441.373.858.801.Keywords: hydrological services, ecosystem protection, economic value of hydrological services, upstream-downstream watershed areas, producers surplus, consumer surplus.ABSTRAK Penelitian tentang pemodelan dan jasa hidrologis dalam perlindungan ekosistem hutan dan Daerah Aliran Sungai (DAS) masih sangat sedikit dilakukan di Indonesia, sehingga penelitian ini akan sangat berguna bagi pemangku kepentingan terkait, karena tujuan penelitian akan menjawab dua masalah, yaitu: (1) faktor apa yang dapat secara signifikan mempengaruhi jasa hidrologis dalam perlindungan ekosistem hutan dan DAS baik di DAS hulu maupun di DAS hilir;  dan (2) menetapkan nilai ekonomi jasa hidrologis di kawasan DAS hulu-hilir. Hasil penelitian menunjukkan: Konsumsi air di daerah hilir sangat dipengaruhi oleh: (a) pengeluaran keluarga pada tingkat signifikansi 96,5%, (b) pendapatan keluarga pada tingkat signifikansi 80,7%, dan (c) pengalaman kerja pada tingkat signifikansi 72,4% dengan uji validasi Model R2 53,00%.
