The majority of the people of Kedungbunder Village, Sutojayan District, Blitar Regency work as farmers and livestock breeders. Farmers in Kedungbunder Village complain that the price of non- subsidized fertilizer is expensive and subsidized fertilizer from the government is difficult to obtain, thus affecting agricultural productivity. This socialization aims to provide understanding and skills to farmers in making and using liquid organic fertilizer from agricultural waste and natural materials in the environment so that farmers can make fertilizer independently. In this way, farmers in Kedungbunder Village are more independent and creative, do not depend on subsidized fertilizer supplies, and reduce operational costs and agricultural activities remain productive, thereby increasing farmer capacity. The methods used in this community service activity include discourse, discussions, and training. The results of community service showed a positive response of 86.76% of participants to socialization activities.

Intestinal diseases caused by transmission from worms as a source of helminthiasis generally occur in areas with subtropical and tropical climate conditions which have a wet climate and lack of awareness among the public regarding maintaining health and sanitation of the surrounding environment. Around 60 percent of Indonesians experience worm infections. The largest age group is 5-14 years old. The prevalence figure is 60 percent, 21 percent of which attack elementary school age children. This disease can be spread by eggs in human waste found in soil and water, therefore awareness of clean and sanitary living is very influential, the process or pattern of feces disposal is also very influential in the spread of this worm. The high rate of soil contamination by Ascaris, which reaches >70%, can also be caused by feces that are thrown anywhere, such as in bushes or around houses close to where you live.  Preventing recurrent infections is very important by practicing clean and healthy living habits such as avoiding contact with soil that may be contaminated with human feces, washing hands with soap and water before handling food, protecting food from soil and washing or heating food that falls on the floor. Several researchers have shown that school age is a group that is often affected by worm infections because they are often in contact with soil. Apart from the government, the role of teachers and parents is very important in providing understanding or knowledge about worms so that they are more disciplined. The aim of community service is to provide knowledge and understanding to class IV/A students at SD N Pannara regarding the dangers of worms and how to prevent them and administer worm medicine.    

Waste is material that has no value or is worthless for ordinary or primary purposes in the manufacture or use of damaged or defective goods in manufacturing or excess or rejected or discarded material. In the provisions of Article 2 paragraph 1, it is also stated that waste managed under the law can consist of: 1) household waste, 2) waste similar to household waste, and 3) specific waste. Community Service (PKM) Socialization to Increase Community Awareness About Waste Management in Alukh Bakhu Village, Southeast Aceh Regency was carried out on 9-11 February 2024, totaling 45 people. Socialization is provided regarding waste and types of waste, sorting productive non-organic waste and special waste, waste management steps, the impact of throwing waste anywhere and sorting waste using 3R. To maintain environmental sustainability, an active role is needed, community participation (not only individuals, most of whom are housewives as the target of activities), support, and collaboration between industry and academic partnerships to encourage the development of waste storage management and its positive contribution to the environment.

This study investigates the effect of roof tile waste used as a partial replacement for fine aggregate on the fresh and hardened properties of concrete, with the aim of promoting more sustainable and environmentally friendly construction materials. The research employed an experimental laboratory method with quantitative analysis. Roof tile waste was incorporated into concrete mixtures at substitution levels of 0%, 5%, 10%, 15%, and 20% by weight of fine aggregate. The workability of fresh concrete was evaluated using slump tests in accordance with SNI 1972:2011, while compressive strength tests were conducted on cylindrical specimens after 28 days of curing based on SNI 1974:2011 standards. The results indicate that increasing the proportion of roof tile waste reduced concrete workability, as shown by a decrease in slump values from 10 cm in the control mix to 8 cm at the 20% replacement level. Compressive strength also exhibited a declining trend, decreasing from 14.63 MPa to 11.90 MPa at the highest substitution, representing an approximate reduction of 18.7%. Nevertheless, concrete containing 5% roof tile waste achieved a compressive strength of 14.32 MPa, which is comparable to normal concrete. These findings suggest that roof tile waste can be utilized as a partial fine aggregate replacement at limited levels. A 5% substitution was identified as the optimal proportion to maintain acceptable workability and strength while supporting sustainable concrete development.
