Abstract

The purpose of this study to determine how much the level of customer satisfaction with the services provided by water drinking regional company (PDAM) of Bengkulu City. Customer satisfaction to clean water services, measured in terms of customer perception in the use of clean water, including water pressure, continuity of water, water quality, and service quality. The research was conducted by distributing questionnaires of 100 respondents. Areas studied as a test site is an area which is distributed by PDAM Surabaya unit, which include Distict of Teluk Segara, Distict of Muara Bangkahulu, and Distict of Sungai Serut. Statistical analysis showed that the water quality variables (X2) be a factor greatly influencing the level of customer satisfaction with a coefficient of 0.427 and the water continuity variables (X3) with acoefficient of 0.276. The level of customer satisfaction with the value 2.340, in the category medium level of satisfaction. The conclusion of the research is to increase the level of customer satisfaction so water drinking regional company (PDAM) of Bengkulu City must pay attention to quality and continuity of water.

Abstract

This study aims to determine the flood discharge plan, discharge the existing channel and analyze the condition of the existing channel and look for alternatives to handling flood inundation at the location of flood inundation. Retrieval of data by measuring the existing channel in the flood inundation location. Calculation of peak discharge uses rational methods for various times of plan return. Rainfall calculation results of the plan that meets the requirements are type 1 Gumbel Method. The results of the research and calculations areknown that the amount of existing channel discharge in seven locations of flood inundation ie left and right Mountain Bambat Road is 0.934 m3 / sec and 3.798 m3 / sec. 2,261 m3 / sec, the left and right Gunung Bungkuk Roads are 0.134 m3 / sec and 0.164 m3 / sec while the flood discharge is 1.897 m3 / sec, Gunung Bungkuk 1 Road is 0.30 m3 / sec while the flood discharge is 0.471 m3 / sec, Gunung Bungkuk Road 4 hunchback of 0.190 m3 / sec while the flooddischarge is 1,336 m3 / sec and Gunung Bungkuk Road is 4 0,173 m3 / sec while the flood discharge is 0,864 m3 / sec and for the drainage of Jalan Gunung Bungkuk is not calculated the channel discharge is due to the channel being closed so that the channel dimension not obtained but for the flood discharge of 2.230 m3 / sec and 0.447 m3 / sec. Thus, it shows that the existing discharge channel on the existing Gunung Bungkuk Hump Mountain Road is unable toaccommodate the planned flood discharge. The alternative to flood inundation is by re-planning drainage channels, channel normalization activities, and improving coordination between the government and the community in maintaining drainage channels.

Abstract

This research about analysis of erosion and land critical level on watershed (DAS) Padang Guci of Kaur Regency is based on few watershed in Bengkulu Province that allegedly has decreased function, which on of it is watershed (DAS) Padang Guci. Watershed (DAS) is an ecosystem which main elements consist of natural resources, water, and vegetation, and also human resources as its user. Several performance indicators of watershed (DAS) that can bemeasured is the index of land cover, forest land cover condition, erosion hazard index, and land management index. Watershed (DAS) Padang Guci has land area about 52689,2 ha. This research using data analysis and maps with Geographic Information System (GIS) in order to get the result of studies that determine the performance of its watershed. The result of the analysis using Geographic Information System (GIS) in the watershed (DAS) Padang Guci is60% of the total area, erosion occur with a very light level. Critical Potential land dominates the cultivation area is 65,41%, while 59,73% critical potential dominates the protected area outside the protected forest. Sediment delivery ratio that obtained was 0,024. The decrease of region function well in cultivation area. It conclude that for the performance of the watershed (DAS) Padang Guci based on land use indicators overall categorized still safe. Keywords : Watershed (DAS), Critical Level’s Area, Erosion, GIS

Abstract

The Irrigation Area of Air Nipis is located in Regency of South Bengkulu at Bengkulu Province with irrigation area 3.116 Ha. Planning and management of irrigation systems is one of the important steps to determine the irrigation water requirement as a whole. The purpose of this research is aim to analyze the water requirement to get value prediction of minimum and maximum irrigation water requirement in irrigation area of Air Nipis using the CROPWAT Version 8.0 method. Irrigation water requirements obtained from CROPWAT Version 8.0 are based on climate data, soil data and plants.The parameters that were reference plant evapotranspiration, effective rainfall, soil treatment, soil data, and plants. The results of the research showed that the maximum irrigation requirement for calculation using CROPWAT 8.0 software occurred in the first 10 days of December (14,49 m3/sec), while the minimum irrigation water requirements for CROPWAT 8.0 occurs in mid to end March (0,04 m3/sec).
