Abstract

River discharge quantity is highly depended on rainfall and initial condition of river discharge; hence, the river discharge has auto-correlation relationships. This study used Vector Auto Regression (VAR) model for analysing the relationship between rainfall and river discharge variables. VAR model was selected by considering the nature of the relationship between rainfall and river discharge as well as the types of rainfall and discharge data, which are in form of time series data. This research was conducted by using daily rainfall and river discharge data obtained from three weirs, namely Sojomerto and Juwero, in Kendal Regency and Glapan in Demak Regency, Central Java Province. Result of the causality tests shows significant relationship of both variables, those on the influence of rainfall to river discharge as well as the influence of river discharge to rainfall variables. The significance relationships of river discharge to rainfall indicate that the rainfall in this area has moved downstream. In addition, the form of VAR model could explain the variety of the relationships ranging between 6.4% - 70.1%. These analyses could be improved by using rainfall and river discharge time series data measured in shorter time interval but in longer period.

Abstract

Ketersediaan data dasar dalam pengembangan kota sangat diperlukan baik dalam rangka perencanaan tata ruang tingkat nasional, propinsi, maupun kabupaten/kotamadia. Hal ini mendukung amanat dalam GBHN 1993 bahwa pembangunan perkotaan ditingkatkan dan diselenggarakan secara berencana dan terpadu dengan memperhatikan rencana umum tata ruang, pertumbuhan penduduk, lingkungan permukiman, lingkungan usaha, dan lingkungan kerja serta kegiatan ekonomi dan kegiatan sosial lainnya agar terwujud pengelolaan perkotaan yang efisien dan tercipta lingkungan yang sehat, rapi, aman, dan nyaman. Permasalahan data dasar dalam perkembangan daerah perkotaan antara lain adalah data dasar dan peta dasar yang belum seluruhnya baku, dan data dasar sumberdaya alam, sumberdaya buatan, dan sumberdaya sosial ekonomi yang sangat dinamis. Pemutakhiran data dasar dan penyusunan basis data digital secara terpadu pada tingkat nasional, propinsi, dan kabupaten/kotamadia perlu terus dikembangkan.

Abstract

The wetland has a strategic role in national development. The potential uses of the wetland are varied such as for agriculture, fisheries, industries, and forestry. The intensive use of the wetland for agricultural development in Sumatera, Kalimantan, Sulawesi, and Papua through transmigration projects has been run since in 1973. Unfortunately, not all the projects were well developed, causing the social, economic, and physical environmental problems. These problems resulted in the negative impact for the life of the transmigration people. For that reason, the community empowerment for the unlucky transmigration people by handling the physical and non physical aspects is very important. This paper will describe the importance of providing spatial data and information biophysical wetland as an initial step in empowering people who live in the wetland resource.
