Abstract

This research aims to design a decomposing blade, sieving system, and test machine products. The method for completing coconut fiber processing machines consists of three stages, namely the design and production process stages, as well as machine product testing. This research produces the following data, namely the design of the untangling knife which is a combination of the functions of the coir untangling knife for random and woven results. Calculation of the equilibrium moment on the shaft obtained a value of ???????????? is 28.68 N and the reaction at point A was ???????????? is 28.32 N, with the diameter of the shaft used in the coconut fiber sieving machine transmission system being Ø28 mm. Fiber uniformity is obtained from twice decomposition processes, whereas the level of fiber/powder uniformity is influenced by the long sieving process time and also the high rotational speed of the sieve.

Abstract

Background. BUMDes Banjarwaru Sejahtera is a business owned and managed by the people of Banjarwaru Village, Cilacap Regency. Some of the businesses that have been managed by BUMDes Banjarwaru Sejahtera include renting molen machines and making handicrafts such as broom handles and woven bamboo household crafts which produce an abundance of wood waste left over from the production process. So far, this wood waste has been sold to tofu craftsmen as fuel for the tofu production process. Purpose. People can use wood waste as added value by processing wood waste into handicrafts that have high economic value so that they can improve the welfare of the people of Banjarwaru village. Through this community service activity, training will be held on the use of wood waste chopping machines so that processed wood waste can be made into handicrafts such as particle boards or other handicrafts. Method. The method used is a lecture method where the community service team who are lecturers at the Cilacap State Polytechnic provide training on the use of wood waste chopping machines to members of BUMDes Banjarwaru Sejahtera and several wood craftsmen in Banjarwaru village. Results. The results of this community service activity have had a positive impact on business development at BUMDes Banjarwaru Sejahtera. Conclusion. Through this community service activity, it can be concluded that this activity has had a positive impact on the business development of BUMDes Banjarwaru Sejahtera. Apart from this, training in the use of wood waste chopping machines can also increase the competence of wood craftsmen in Banjarwaru village so they can produce more varied crafts made from wood waste.

Abstract

Many farmers Banjarwaru complain that goat growth is less than optimal, and low productivity. Based on these problems, this community service program aims to ensure that farmers understand and are able to manage goat farms according to standards independently. The method used in this community service program is to look at achievement indicators from socialization activities and cage management training and animal health recording. Based on the achievement indicators from this activity, it shows that 100% of the 20 breeders understand livestock management, housing, and the correct way to record livestock health. A total of 15 people have been able to use maintenance tools and techniques for handling diseases infected by livestock. Based on the results of the achievement indicators obtained from this service activity, it was concluded that breeders in Banjarwaru Village knew and understood the correct way to raise goats and were able to carry out maintenance activities according to good standards.

Abstract

Sabut kelapa, salah satu komoditi di Cilacap, memiliki potensi besar sebagai bahan olahan untuk berbagai aplikasi termasuk sebagai pengisi komposit geopolimer. Namun, kandungan lignin yang tinggi pada serbuk sabut kelapa dapat menghambat pemanfaatannya secara optimal. Delignifikasi alkali merupakan metode yang digunakan untuk mengurangi lignin dan meningkatkan selulosa. Penelitian ini bertujuan untuk mengetahui pengaruh delignifikasi alkali terhadap perubahan struktur lignoselulosa serbuk sabut kelapa, sehingga hasil penelitian ini dapat dijadikan referensi pada optimalisasi sifat mekanik komposit geopolimer. Metode penelitian meliputi perlakuan delignifikasi alkali, dengan variasi konsentrasi 1% dan 2% larutan NaOH, pada serbuk sabut kelapa dan karakterisasi struktur lignoselulosa menggunakan Chesson-Datta dan FTIR (Fourier Transform Infra Red). Hasil penelitian menunjukkan bahwa perlakuan delignifikasi alkali berhasil menurunkan kadar lignin pada interval 9% - 11% dan mengubah struktur lignoselulosa serbuk sabut kelapa. Berdasarkan hasil FTIR, puncak serapan bilangan gelombang 3310,83 cm-1 membuktikan adanya gugus fungsi O-H stretch, pada bilangan gelombang 2917,56 cm-1 membuktikan adanya gugus fungsi C-H Stretch. Puncak bilangan gelombang 1370,68 cm-1 membuktikan adanya gugus fungsi C-H bend dan pada bilangan gelombang 1225,78 cm-1 membuktikan adanya gugus fungsi C-O stretch.
