Abstract

There are several problems in Setrohadi Village, Duduk Sampeyan District, Gresik Regency, such as the lack of a clean water source from the lake which they use for their daily needs. To overcome this problem, lake water is processed into clean water by building a water treatment reactor and combining it with an upflow aeration and filtration system. Filtration is carried out using several filter materials including quick sand filter, manganese filter, zeolite filter, activated carbon filter, and paranet. Apart from that, two materials are also used which are key to water purification, namely silica sand and carbon. The aim of processing lake water into clean water is to meet the needs of the Setrohadi Village community for clean water, to improve the quality of lake water, and to provide feasibility for water consumption. The result of this water treatment is that the people of Setrohadi Village can enjoy clean, safe and quality water. From tests using variations in the use of activated carbon and silica sand, it was found that pH = 6.77, TDS = 249 ppm, %Cl = 0.02% and Cl = 524 mg/L. From the test data it can be concluded that the pH obtained is almost neutral which can be used for daily needs and consumption, so that the requirements for clean water have been met.

Abstract

Pacul Gowang Hamlet is one of the hamlets located in Jatirejo Village, Diwek District, Jombang Regency. Most of the residents of this hamlet work as farmers with main commodities such as rice, corn, and vegetables. However, the farming method used is still traditional, namely planting directly in the soil, which often results in suboptimal yields. The problems faced include unproductive land, low farmer income, lack of knowledge regarding modern cultivation technology, and limited understanding of post-harvest handling and product marketing. This community service program was carried out based on a situation analysis and discussions with local farmers. The purpose is to provide a solution by introducing the hydroponic drip fertigation system, a technique of supplying nutrients through drip irrigation controlled by a timer with high precision. This system was chosen because it is more efficient in water and nutrient usage, reduces the risk of crop failure, and can be applied to limited land areas. The crop cultivated is the Sweet Net 9 melon variety, which has a high market value and stable demand, such as from supermarkets and restaurants. This activity involved 10 KKN (Community Service Program) students to utilize idle land in order to produce high-quality horticultural products, thereby increasing the income and welfare of the Pacul Gowang Hamlet community.
