Reed bed treatment is put in the context of a major water company’s need to provide reliable, high quality, effluents from small sewage treatment works whilst seeking to minimise running costs. Design and operational information is given for reed bed applications in Severn Trent Water. Performance details are provided for application to secondary, tertiary and storm overflow treatment. The results give particular confidence in the system’s ability to deliver very high quality effluents when used for tertiary treatment, the company’s biggest application. Reed beds work well against less demanding criteria for secondary treatment at small sites and show great promise for storm overflow treatment.

Small communities will often need alternative systems of water supply, sanitation, washing and wastewater disposal facilities. Numerous agencies supply various models of ablutions facilities. The Remote Area Hygiene Facility comprises laundry, shower, toilet, wastewater disposal trench, solar water heater, chipheater, hand-operated washing machine and washing line. The toilet is a water–seal, low water demand, pit type. A plastic, solar water heater has been developed to overcome the problems experienced by commercial, metallic units such as blockages, breakages and ruptures due to freezing. The plastic design is more durable in the chosen environment and quite easy to assemble. Wastewater disposal is by evapotranspiration which is shown to be more effective than leach drains in tight, clay soils and promotes the growth of trees and shrubs. The Remote Area Developments Group proposes the installation of these units as community–based training projects to provide general construction skills, environmental hygiene education and a commitment to maintenance.

ABSTRAKTidak mampunya kita mendalami pengetahuan asli kita sendiri mengakibatkanterjadinya disharmoni teknologi dengan kebutuhan di lapangan, tidak terkecuali TeknologiTepat Guna (TTG) dalam pertanian ladang. Tujuan penelitian ini adalah untuk mengetahuiperanan Aseuk Hatong dalam tradisi pertanian ladang di masyarakat Tatar Karang PrianganKabupaten Tasikmalaya yang religius Islami, tapi masih mempertahankan tradisi tersebut.Metode penelitian ini menggunakan studi fenomenologi Schutz. Hasil penelitian menunjukkanbahwa 1) Seni berkomunikasi: (kakawihan) dalam tradisi Aseuk Hatong adalah upayaharmonisasi antara petani dengan alam yang sedang kemarau melalui senandung ringan yangkontekstual. 2) Teknologi Tani: (Aseuk Hatong) adalah suatu alat untuk mengolah untuk tanahladang pada musim kemarau yang dibalut dengan estetika musikal sederhana khas petaniladang, hasil pengembangan teknologi yang tepat guna, menyenangkan, inovatif, fungsional,terjangkau, murah, dan ramah lingkungan. Dengan demikian, dapat dirumuskan bahwa TradisiAseuk Hatong di Tatar Karang Priangan merupakan media persuasif bertani di kala ngahuma(berladang) tidak dibarengi musim penghujan. Tradisi Aseuk Hatong juga merupakanpengembangan teknologi yang sangat memperhitungkan kearifan lokal yang berlaku.Kata kunci: aseuk hatong, kawih, komunikasi seni, teknologi tani, pertanian ladangABST RACTOur inability to deepen our own original knowledge results in disharmony of technologywith the needs in the field, including the Appropriate Technology (TTG) in agriculture. It istherefore that in any development it is often not harmonious with the needs of society. Theobjective of the research is to know the role of Aseuk Hatong in the agricultural tradition in theTatar Karang Priangan community of Tasikmalaya Regency whicht is religiously Islamic yetstill maintains the tradition. The research method is Schutz phenomenology study. The resultsof research show that (1) the art of communicating (kakawihan) in Aseuk Hatong tradition isa harmonious effort between farmers and the dry nature through mild, contextual humming.(2) Farm technology (Aseuk Hatong)is a tool to cultivate the soil, plowing the fields during thedry season by wrapping with simple typical musical aesthetics of field farmers as the resultsof appropriate technology development, fun, innovative, functional, affordable, cheap, andenvironmentally friendly. As the conclusion, it can be said that Aseuk Hatong Tradition in TatarKarang Priangan as a persuasive media farming during ngahuma (farming) not accompaniedby rainy season is a technology development that takes into account local wisdom occur.Keywords: aseuk hatong, kawih, art communication, farming technology

The use of maize waste plant materials (stem, leaf, and husk cover) have high economic value to be processed become organic fertilizer for agricultural land fertilizer. Maize have several and quite high contents of macro and micro nutrients. This activity was hoped that the farmers can overcome the increasing price of inorganic fertilizer recently and furthermore farmers can reap higher income. Beside higher income the use of organic fertilizer can improve the nature and behaviourof land through improving of soil chemical, soil physical, and soil microorganism. Therefore, the appropriate technology for processing of maize become organic fertilizer is very important to be diffused or socialized to farmers.Keywords: fertilizer, maize waste

Generally, wastewater of nata de coco industry contains suspended solids and COD were high, ranging from 90,000 mg / l. The high level of of the wastewater pollutants, resulting in nata de coco industry can not be directly disposed of its wastewater into the environment agency. Appropriate technology required in order to process the waste water so that the treated water can meet the environmental quality standards that are allowed. Designing the waste water treatment plant that is suitable and efficient for treating industrial wastewater nata de coco is the activated sludge process. Wastewater treatment using activated sludge process of conventional (standard) generally consists of initial sedimentation, aeration and final sedimentation.Keywords : Activated Sludge, Design, IPAL
