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

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.

Abstract

AA5083 series aluminum is one of the primary materials used in ship construction due to its excellent weldability in conventional welding processes, such as arc welding. However, similar to other aluminum alloys, the weakness of AA5083 is the occurrence of frost cracking during the welding process, especially in the HAZ and the large amount of distortion.. The research was conducted by providing additional treatment in the form of in-situ rolling on friction stir welding (FSW). The in-situ rolling treatment used a single roll positioned directly on the weld area and behind the FSW tool and moving simultaneously with the welding process and with a roll load of 8000N. The characterization carried out included thermal cycle measurements, microstructure observations, hardness value distribution testing, distortion measurements and tensile testing. The results showed that the largest distortion value occurred in the welded material without additional treatment (as welded) of 2.81 mm, while in the material with additional treatment (mechanical), the distortion value was smaller at 1.1 mm. The mechanical specimen had the best mechanical qualities, with a tensile strength of 225.5 MPa and an average hardness value of 61 VHN, whereas the as-welded specimen's tensile strength was 201.8 MPa. This phenomenon occurs because the specimen, with the addition of in situ rolling, experiences grain refinement, and it seems that this is consistent with the Hall-Petch relationship, σ_y=σ_0+k_y d^(-1/2)Materials with fine grains are harder and stronger than materials with coarse grains, because fine grains have a larger total grain boundary area to hinder dislocation movement. The tensile fracture position was in the advancing side region, where higher heat input occurred in this region than in the retreating side.

Abstract

Kabupaten Cilacap memiliki potensi perikanan tangkap yang sangat besar, namun hasil tangkapan ikan tidak hanya terdiri atas jenis-jenis ikan yang diinginkan, tetapi juga terdiri atas jenis ikan-ikan kecil yang kurang diminati oleh pasar atau disebut sebagai ikan rucah. Ikan rucah yang tidak bernilai ekonomis pada umumnya hanya dibiarkan membusuk dan dibuang ke lingkungan. Tujuan utama kegiatan pengabdian ini adalah untuk mengoptimalkan pengelolaan hasil laut di wilayah Cilacap, dan meningkatkan kesejahteraan masyarakat melalui pemanfaatan hasil samping tangkapan ikan dan mengurangi jumlah ikan rucah yang terbuang percuma ke lingkungan. Metode pengabdian yang diterapkan untuk menjadi solusi adalah sosialisasi dan penerapan teknologi alat pemisah daging dan tulang ikan rucah. Hasil kegiatan pengabdian menunjukkan tingginya antusiasme masyarakat dalam penerapan teknologi, sehingga 70% dari masyarakat yang mengikuti kegiatan telah mampu mengoperasikan mesin secara mandiri termasuk dalam aspek keamanan dan perawatan dasar, dan masyarakat telah mampu mengolah ikan rucah dengan kapasitas mencapai 50 kg/jam.

Abstract

Banjarwaru village is one of the villages in Cilacap district with the potential for wooden broom handle craft commodities. The processing of mahogany wood (Swietenia mahagoni) into broom handles produces wood waste that has not been utilized optimally. The accumulation of wood waste is caused by a lack of knowledge among the Banjarwaru village woodworking community regarding the potential dangers, benefits, and economic value of wood waste. Therefore, training in wood waste processing into value-added products such as particleboard is needed. The Community service team together with BUMDes Banjarwaru carried out mentoring activities as a solution method for utilizing wood waste. The mentoring activities carried out consist of educating the negative effects of wood waste on the environment, educating the potential and benefits of wood waste in another processed forms, and training in wood waste processing into particleboard. These series of activities succeeded in increasing the woodworking community understanding of wood waste by 81.6%. The success rate of mentoring reached 91,67% shown by 11 out of 12 mentoring participants understood the potential danger, benefits, and other processed forms of wood waste.
