Abstract

Apart from its function as a soil cover, forest also plays a positive role in preserving water and sediment in a river basin. Rain water which is abundant in the rainy season is caught and stored underground, so that the erosion and flood hazard can be eliminated. In the dry season groundwater becomes reservation to minimize and even eliminate the risk of water shortage. This preliminary study is to monitor suspended sediment transport with respect to the forest area of upper Citarum River Basin at upper Citarih Sub - River Basin. On the basis of the preliminary study results, it can be said that for a river basin where percentage of the forest area is smaller (i) the suspended sediment concentration is higher and (ii) the total sediment per area unit is greater. These indications were found during the study period, from September 1987 to February 1988. The preliminary study was conducted in a sub-river basin where the soil type is a mixture of andosol and brown regosol, and the terrain is undulating, hilly to mountainous with slope more than 15 percent.

Abstract

Program komputer dengan nama "WTRBLNI" adalah program komputer untuk mengevaluasi imbangan air yang dikemukakan oleh Thornthwaite-Mather. Program ini terdiri dari dua file, yaitu file programnya sendiri (WTRBLNLEXE) dan file untuk menyimpan data faktor f(WTRBLN.IND). Faktor f ini berguna untuk mengoreksi nilai evapotranspirasi potensial yang dihitung berdasarkan indek panas dan temperatur bulanan rata-rata. Faktor f ini juga tergantung dari Ietak lintang suatu daerah dimana evaluasi imbangan air ini dilakukan. Program ini dapat mcnentukan kapan perhitungan runoff dimulai. Program ini tidak dapat melakukan perhitungan imbangan air secara siklis tetapi secara berurutan dari bulan ke bulan tergantung kapan mulainya. Penentuan herapa tersedianya air untuk runoff bulan berikutnya dapat kita berikan sehagai masukan, misalnya 50 persen. Program ini ditulis dengan menggunakan Bahasa Basic untuk komputer IBM-PC dan kompatibclnya.

Abstract

This paper deals with employment opportunities in the urban areas of Indonesia. The informal sector is present in almost every city in this country. The existence of the informal sector is usually associated with the lack of labour absorption capacity of the formal (modern) sector. The informal sector serves as a buffer against the lack of formal employment opportunities and the consequent unemployment. Nearly one third of the working force in Indonesia cities work in the informal sector Those active in this sector usually are in the fully economically productive age brackets. The Informal sector can serve as a buffer power against the employment opportunity and unemployment. This can be seen from the fact that nearly one third of the working labour in cities work at the informal sector. Whereas, those who are engaged in the informal sector are at the fully productive age.

Abstract

Current information of landuse and landuse type change within a certain period of time is chiefly needed in a landuse planning. The information of landuse type change is obtainable through overlapping landuse maps of one period. However, the common problem is inavailability of the latest maps, especially those of the areas where the landuse change is rapid. The aerial photographs and remote sensing image can be used to solve the problem. Nevertheless, another problem which is not less important is the need for rapid analysis with high accuracy. For this purpose, computer well-known as Geographical Information System (GIS) is used . One of the GIS components is software, while USEMAP is one of the various hinds of software. The use of USEMAP for landuse change analysis is very effective, especially for the quantitative one. However, USEMAP has some shortcoming, namely this can only be used to analyze seven landuse types.
