Abstract

Penggunaan koagulan lateks yang tepat mampu menghasilkan karet bermutu baik. Namun, jaminan ketersediaan dan harga koagulan anjuran menyebabkan petani karet beralih menggunakan koagulan non-anjuran, sehingga dalam penelitian ini mencoba meneliti tentang karakteristik morfologi dan mutu karet yang dihasilkan oleh koagulan anjuran asam formiat dan koagulan non-anjuran asam sulfat. Hasil penelitian menunjukkan bahwa bobot basah koagulum asam formiat lebih berat dibandingkan bobot basah koagulum asam sulfat, meskipun waktu koagulasinya lebih cepat dibandingkan waktu koagulasi asam formiat.  Mutu karet yang dihasilkan oleh asam formiat berdasarkan kadar karet kering, kadar abu dan kadar zat menguapnya lebih baik dibandingkan dengan mutu karet yang dihasilkan oleh asam sulfat.Kata kunci: Koagulasi; asam formiat; asam sulfat

Abstract

In recent years, the concept of smart villages has gained increasing prominence as a means of encouraging sustainable development in rural areas. This is particularly relevant in the agricultural sector, where the potential of land resources is crucial. Cukilan Village, located in Suruh District, Semarang Regency, Central Java, is primarily an agricultural area, with over 80% of its land designated for agricultural purposes. The village government has expressed a desire to develop Cukilan as a smart village through an FGD process. Based on this background, a community service program was implemented with the aim of designing Cukilan Village as a smart village in stages, to enhance economic growth and prosperity by leveraging the potential of agricultural resources and human resources, as well as accelerating the village development process. The method for implementing this PKM (Community Service) program utilized the Assets-Based Community Development (ABCD) approach, which involved outreach, discussion, mapping of agroecological zones, as well as land suitability and evaluation. As a result of this initiative, the Cukilan Village government received guidance for an ideal agricultural system based on land resource potential, which serves as a basic component towards the realization of Cukilan Smart Village.
