Abstract

The demand for groundwater in developing countries is continuously increasing. It is used as industrial processes, drinking, agriculture, fishpond and irrigation. The reasons for this growth include agriculture, industrial processes, expanding cities, food production needed irrigation areas that urgently need groundwater supply. Actually now, in south Kulon Progo coast area, many people development agriculture with water supply from groundwater. From the measurement in the field concerning groundwater resources potential in thesouth Kulon Progo coast area, can be predicted that the fresh water resources be found as far as coast from Serang River until Progo River, with average wide 1.6 km and thick between 20 – 43 meter and with depth average 25 meter.

Abstract

Pumping tests are carried out to determine how much groundwater taken from a well and what effects pumping will have on the aquifer. Theis recovery method aims to find out the aquifer characteristics such as transmisibility and permeability values. This method in principle observes the recovery of ground water surface. This reasearch location at Mangkubumi distric Tasiklamaya West Java. The value of transmisibilitas and permeabilitas in Mangkubumi district indicated the groundwater potential is good. Ground water flow (m3/day) between 684,02 at Cipawitra until 4.617,19 at Cipari Tasikmalaya. Hidrolik Conductivity between 0.39 – 2.63 (m2/day).

Abstract

Marine culture develoment at Semarang Central java coast is notincreased. Based on water quality, a good water quality conditions at line 3,beside far for human activities, the dissolved oxygen and turbidity level stillsuitable for marine culture activities. The dissolved oxygen value from 4.8 – 5mg/l. Comparing with the second station (line l and 2) dissolved oxygen (DO) israther low and turbidity level is very hight, turbidity value until 4 FTU. The method using digital device Chlorotech type AAQ 1183, Alecs Electronics for describing the characteristicsof tropical coastal hydrography and water quality.

Abstract

PT. Medco Ethanol Lampung has been constructed factory for cassavaand mollase processing in order to product Rectified-Ethanol at Talang JaliVillage, Kotabumi North Lampung. The estimation of capacity productionis around 190.000 liter per day. Maximum necessity of fresh water forfactory operasional is about 8.507 m /hari. For the measurement depthand water volume Tirta Shinta Reservoir get the volume is about3.155.434 m with the avarage depth for 1 – 6 meter, while the dischargeof water at outflow for agricultural is about 138.270 m per day at rainyseason. If the water from Tirta Shinta reservoir use for main factory, andthe total capacity reservoir only used 4.3 %, if nothing flow from riverbecause dry season, and now Tirta Shinta reservoir can be supply only17.7 month during dry season. Based on the environmental aspect, ifbetter, a fresh water supply for ethanol factory from river has a big rate offlow. This present, beside for farming activity and tourism, the most ofsurface water reservoir covered by water plant that make problem forfactory operational, specially for water pump.

Abstract

Pumping test are carried out to determine how much groundwater taken from a well and what effects pumping will have on the aquifer. Theis recovery method aims to find out the aquifer characteristics such as transmisibility and permeability values. This method in principle observes the recovery of ground water surface until stable. This research location at Tamansari distric Tasikmalaya West Java. The value of transmisibilitas and permeabilitas in Tamansari district indicated the groundwater potency is not good for industry ot comercial water. Higher value at Sukahurip and lowest value at Bantarhuni with a permeability coeficient only 1.32 m2/day. Ground water flow (m3/day) between 410 – 4868 m3/day at Mugarsari. Ground water resources is limited potency, especially at dry season, local goverment need to conserv with a build pond or fishpond for reserve water.
