Abstract

Population growth has an impact on development in various sectors. One of the sectors affected is the housing sector. In determining the location of housing requires a complex analysis in order to create a decent housing area. In the 2014-2034 Samarinda City Spatial Plan, certain locations have been determined to become residential areas. Palaran sub-district was chosen and prepared to become a high-density residential area. In this study, an analysis was carried out on the power of shamans for residential land in Palaran District. The analytical technique used to determine the carrying capacity and adequate capacity for housing is the Land Carrying Capacity Analysis Method which has been stipulated in the Regulation of the Minister of Public Works No. 20/PRT/M/2007 and the Indonesian National Standard 03-1733-2004 concerning Residential environmental planning procedures. In the analysis process, the data used are the Samarinda City Spatial Plan in 2014-2034 and the Draft RDTR of Palaran District. In the analysis of the carrying capacity of the land, the results of the land capability are divided into 5 classes. High development capability 1.091,01 Ha; rather high development capability 3.463,87 Ha; medium development capability 2,742,79 Ha; low development capability 8,963,35 Ha; and very low capacity 2,394,37 Ha. Based on the results of the analysis, it is obtained a suitable location for housing development in Palaran District.

Abstract

Alum merupakan koagulan yang umum digunakan untuk menurunkan TSS dalam air. Fungsi koagulan adalah untuk mendestabilisasikan partikel koloid sehingga dapat menurunkan kandungan partikel terlarut dan tersuspensi. Koagulan dapat berasal dari bahan alami, seperti kitosan, yang dibuat dari limbah. Limbah kulit udang yang dihasilkan oleh salah satu perusahaan di Kabupaten Kutai Kartanegara mencapai 4,5 ton per bulan. Jumlah yang cukup besar tersebut mendorong pemanfaatan limbah menjadi kitosan sebagai koagulan limbah cair tekstil yang memiliki kandungan TSS melebihi baku mutu, yaitu 518-620 mg/L. Penelitian ini bertujuan untuk mengetahui efektifitas kitosan sebagai koagulan, serta membandingkannya dengan koagulan alum dalam menurunkan TSS. Kitosan dibuat melalui proses preparasi, deproteinasi, demineralisasi, dan deasetilasi. Pengontakkan koagulan dengan limbah cair tekstil menggunakan jartest dengan 100 rpm selama 3 menit dan 40 rpm selama 12 menit. Konsentrasi koagulan kitosan yang digunakan adalah 100, 120, dan 150 mg/L, sedangkan untuk koagulan alum menggunakan dosis optimum. Hasil penelitian menunjukkan bahwa kitosan mampu menurunkan TSS mencapai 89,5% atau 555 mg/L, dengan dosis optimum 150 mg/L. Pada dosis optimum, koagulan tawas mampu menurunkan hingga 91,9% atau 570 mg/L. Efisiensi tawas yang sedikit lebih tinggi dari kitosan menunjukkan bahwa kitosan mampu berperan sebagai koagulan limbah cair tekstil seperti halnya alum.Kata Kunci : kitosan, limbah cair, alum, tekstil, TSS

Abstract

West Kutai Regency, especially in Damai District, is one of the regions in Indonesia that has great potential for coal natural resources. Coal mining certainly requires sufficient space for its mining activities, therefore it is the regulation of space that will later regulate and limit the excessive use of land. This study uses the DPSIR method where the DPSIR component requires a response from the community. The criteria for resource persons are competent and have influence in making decisions regarding something related to environmental issues in Damai District. Furthermore, the selected resource persons must also be those who are willing to be interviewed. The driving of changes in the use of coal mining land in Damai District is due to demographic factors as well as economic growth. The pressure that occurs is in the form of land clearing and expansion of mining land, thereby reducing existing land resources and increasing mining activities, which in turn increases other environmental pressures. Other pressures, such as increasing waste disposal activities, increase the volume of waste due to the increase in the number of coal mining areas. The latest conditions, namely the results of monitoring the condition of the water and air are still quite good, it's just that in the waters of the Kedang Pahu River there are findings of iron content that still exceeds the threshold. The impact of the increase in mining land in the form of reduced land resources, increased potential for erosion that can cause flooding, reduced environmental quality and interfere

Abstract

AbstractSoil erosion is one form of soil degradation or transported to another place by a natural medium. One of the effects of erosion are silting in water bodies such as reservoirs or lakes. The purpose of this study was to determine the rate of erosion and its factors that cause erosion in the reservoir area of Benanga Lempake Samarinda. The amount of erosion that occurs can be determined using the equation Universal Soil Loss Equation (USLE) by Wischmeier and Smith (1978), which consists of factors erosivitas rainfall, soil erodibility, length and slope, crop management and soil conservation. The results of the processing overlapping of the four map erosion factors by using software Geographic Information System (GIS) resulting in erosion value and distribution class erosion. The Results of analysis data obtained value erosion in the reservoir area Benanga Lempake Samarinda are 6.496,62 ton/ha/year. Based on the analysis and prediction of erosion of the magnitude of the erosion can lead to sedimentation occurred in Benanga Lempake Samarinda Reservoir, so that the incoming water due to rain and water runoff from the Karang Mumus Watershed is not dammed by the dam so that the water overflowed and caused flooding. Erosion prevention efforts need to be done such as soil and water conservation. Keywords : Soil Erosion , Reservoir, Geographic Information Systems.
