Abstract

Areas of Jakarta, Bogor, Tangerang and Bekasi (Greater Jakarta) is an area with high rainfall (2250 -2500 mm/year). The rain that falls in this region often cause flooding problems in the area of rice fields, settlements and even in downtown. Rain is a gift from God to be utilized to the maximum extent possible for everyday purposes. Rain Water Harvesting is an attempt to capture rainwater that falls on the roof. In this study, use of the roof area of about 300 -500 m2. Precipitation that falls on the roof is channeled and put into storage, by first filtering done to reduce the dirt. The volume of rain water storage for each location is 10 m3, medium intensity rain (15-20 mm/h), sufficient to meet the storage within a few hours. Rain Water Reservoir are equipped with water pump which has a capacity of 25 liters/minute, the water can be used for flushing toilets and spraying crops. If Rain Water Reservoir is full, water overflows into the Artificial recharge well. The results of analysis with Kostiokov calculation method used to calculate the infiltration rate of Artificial recharge well and calculate the cumulative volume of infiltration at the Artificial recharge well. Results of tests conducted are as follows: a). In Depok, the infiltration rate of Artificial Recharge Well is about 12 mm/minute and was relatively stable at 140 minute (2 mm/minute). It also has the ability to recharge  450 liters of water in 140 minutes. b). In South Jakarta, the infiltration rate of Artificial Recharge Well is about 11 mm/minute and was relatively stable at 160 minutes (2.5 mm/minute). Artificial Recharge Well has the ability to recharge  480 liters of water  in 160 minutes. c). In Bantarjati, Bogor,  Artificial Recharge Well have the highest capacity, namely 45 mm/minute and was relatively stable at 260 minutes (2.5 mm/minute). Artificial Recharge Well has the ability to recharge 1000 liters of water  in 150 minutes. Rain Water Harvesting Development Efforts and Artificial Recharge Well very useful to overcome inundation in residential areas, especially during heavy rain, because it can reduce the volume of surface water into the channel simultaneously. Keywords : Rain Water Harvesting, Infiltration, Artificial Recharge.

Abstract

Pangkajene archipelago, is archipelago comprising 117 islands scattered in the West Coast District Pangkajene. The islands were inhabited by populations ranging from 10 to 250 heads of families. Most of the population livelihood as a fisherman. To support the daily basic needs are still supplied from the mainland, including the need for clean water. Community water needs during this time a lot depends on rain water that collected or from shallow groundwater. In line with population growth, water demand increases, so frequent water shortages, especially during the dry season. Sea water treatment technology with reverse osmosis systems is an alternative to the settlement of water shortage on the island, but because the number of islands many, it will be difficult to meet the needs of water in a short time. Therefore chosen the middle position of the three islands (Cakdi Saroppe Island, Island and Island Sanane view) as a distribution center. Installed capacity for each of the islands is 10 m3/day, which can serve to the needs of drinking water a thousand people. Water treatment technology with reverse osmosis pretreatment consist of the form of multi-media filter consisting of silica sand, zeolite, and activated carbon, followed by cartride filter and a reverse osmosis membrane. Construction of the water treatment unit involves people since it began surveying best location, construction, training and initial operation. Water that has been processed can drink for everyday purposes, therefore, to support the operations of the water is sold to the public for replacement of operational money. The biggest cost needed to produce water is the cost of fuel. By managing the sale of water expected operating costs can be met and comunity get drinking water at an affordable price.Keyword : dringking water, reverse osmosis, society engangement.

Abstract

The existence of regulations to control environmental pollution has grown over time in line with changes in environmental legislation. In Indonesia since the '80s has been three times experience changes in environmental legislation. Any change in the law is always followed by changes in regulations that are below it. From time to time, the environmental pollution is getting worse and require stricter regulations and implementation. Regulations are too strict sometimes not implementable and eventually are violated because there is no way out solution that does not burden the parties. Domestic waste is the largest portion of urban waste. Its existence has made the environment of rivers, lakes and ground water polluted, due to not properly managed. Regulation of waste quality standards have been tightened over time. Waste water quality standard is the limit or polluted substance or the amount of pollutant elements are tolerable in the waste water to be discharged or released into the water source from a business or activity. The existence of environmental quality standards in Indonesia are set by regulations of environment ministers. Discharge of domestic waste quality standards number P.68 / Menlhk / Secretariat / Kum.1 / 8/2016 has brought on changes in the use of domestic wastewater treatment technologies, as happened tightening in several key parameters, which is still within the limits loose. Keywords : Environmental regulation, waste treatment technology

Abstract

Penggunaan air tanah sebagai sumber air bersih untuk digunakan sebagai air minum sering terkendala oleh kualitas air mengandung besi terlarut yang cukup tinggi. Kandungan zat besi diatas 0,3 ppm menyebabkan sumber air tersebut tidak layak digunakan sebagai sumber air baku air bersih dan untuk kandungan besi diatas 0,05 ppm menyebabkan sumber tersebut tidak layak digunakan sebagai sumber air minum.  Air baku dengan kualitas seperti itu sebaiknya dilakukan pengolahan terlebih dahulu.  Air tanah yang berasal dari daerah vulkanik aktif dengan batuannya banyak mengandung zat besi terutama dari daerah yang sering mengalami perendaman air seperti daerah bekas sawah atau bekas rawa. Proses kimiawi yang bekerja di wilayah ini tersebut pada umumnya adalah proses reduksi. Pada umumnya besi yang ada terlarut dalam air adalah sebagai Fe2+ atau Fe3+, dalam ikatan kimia sebagai Fe2O3, Fe(OH)2 Fe(OH)3 ataunFeSO4. Setelah dilakukan ekploitasi atau pengambilan air tanah dan air baku tersebut mengalami kontak langsung dengan udara, maka akan berwana kecoklatan, berbau amis seperti karat besi. Ada tiga cara penurunan zat besi dalam air yaitu dengan cara 1. Aerasi, 2. Sedimentasi dan 3. Filtrasi. Dalam percobaan ini proses penurunan zat besi dilakukan dengan cara aerasi yaitu dengan mengaplikasikan penggunaan gelembung mikro yang dihasilkan dari generator pembangkit gelembung mikro dan dengan filtrasi. Pembangkit gelembung micro ini dibangkitkan oleh pompa KTN Merk Nikuni menghasilkan gelembung udara dengan diameter 20 micron yang digunakan sebagai bahan oksidator untuk air baku mengandung besi. Setelah proses oksidasi berlangsung dalam periode waktu tertentu kemudian disaring dan diukur sisa kandungannya. Hasil percobaanadalah pada kandungan besi dalam air baku sebesar 1,16 ppm yang direaksikan dalam sebuah reactor maka efisiensi oksidasi dapat dicapai dengan baik dan berhasil menambah kelarutan oksigen dalam air sebesar 71-80 % dan menurunkan zat besi dalam air baku sampai mencapai 38-56 % pada pH 7. Kesimpulan yang dapat diambil melalui percobaan ini adalah bahwa generator gelembung mikro mampu digunakan sebagai sebuah cara untuk mengoksidasi zat besi terlarut dalam air baku dan dapat dimanfaatkan sebagai sebuah cara untuk meningkatkan kandungan oksigen terlarut air baku.Kata kunci: air tanah, zat besi terlarut, pembangkit gelembung mikro, oksidasi
