Abstract

Coconut shell charcoal is a by-product waste from coconut farming which is very abundant and its use has not been optimally applied other than being limited to burning it for boiler energy as a heater and other parts of it being used as a fuel source for cooking. As raw materials for making wooden boats for fishermen in Indonesia become increasingly scarce, efforts are needed to find replacement materials in the supply process. However, another very urgent factor is that it is absolutely necessary to develop environmentally friendly composites to replace synthetic composites which are difficult to decompose. However, composite materials made from natural fibers still have many weaknesses, including low mechanical strength, therefore applications in the engineering field are still under study and development. Some of the weaknesses of natural fiber composite materials, which need to be studied, include their brittle nature and easy cracking. One of the things carried out in this research is a synthetic material derived from unsaturated polyester reinforced with natural fibers from coconut shell charcoal particles which is used to reduce the percentage of synthetic material from polyester which can form a composite that is easily decomposed. From the research, the mechanical strength obtained with a polyester mixture matrix reinforced with coconut shell charcoal fibers obtained crack resistance values with a large critical stress intensity factor based on ASTM D 5405 by varying the composition of the shell charcoal fiber mixture from: 0%, 10%, 20%, to 30%. From the test results, the largest critical stress intensity factor at K_1c= 1.624 (MPa/m1/2) occurred in 20% coconut shell charcoal fiber.

Abstract

This study aims to design an efficient boat-pulling machine to support traditional fishermen at Pasie Katapiang Beach, Padang Pariaman. The research method employed is the design of the tool based on the principles of design engineering, involving a systematic process in creating a machine that can assist fishermen in the boat docking process more efficiently. Through calculations and planning, it was found that the force required to pull the fishermen's boat is 6,522.88 N, using a shaft made of ST 37 material with a diameter of 22.413 mm. The rotations generated on the transmission shaft are 2000 rpm, while on the wheel and drum shafts are 750 rpm and 500 rpm, respectively. The selection of a slip clutch with 2 bolts on the transmission shaft and the use of pillow block bearing ucp 206 ass 30 with specified bearing life estimates have been considered in the machine design. Practical test results indicate that the time required to reel or pull the boat is 0.98 minutes. In this research, the design of the boat-pulling machine meets operational needs. It has the potential to positively contribute to improving the work efficiency and welfare of traditional fishermen in the field

Abstract

Orchid is an ornamental plant commodity that has an important meaning in international trade. Until now, orchids are still the center of attention of farmers and lovers of ornamental plants, because of their bright potential as cut flowers and potted plants. The popular and widespread type of orchid is Cattleya sp. The Cattleya orchid is also called the queen of orchids because of its colorful flowers. Cattleya sp. orchids take a long time to propagate by seed, about 4 to 7 years, so other methods are needed to deal with them. Tissue culture is a method for isolating plant parts such as cells, tissues or organs, and cultivating them in an aseptic environment. The purpose of this study was to determine the optimal interaction of growth regulators indole acetic acid (IAA), benzyl amino purine (BAP), and their interactions with the root induction of Cattleya sp. Cytokinins interact with auxin in determining the direction of cell differentiation. In this research method, differences in concentrations of indole acetic acid (IAA: 0, 2, 4, 6 ppm) and concentrations of benzyl amino purine (BAP: 0, 0, 5, 1 ppm) were carried out. Parameters observed were the number of roots and root length. Data were analyzed descriptively and inferentially using ANOVA. The highest number of roots was obtained in the treatment medium containing 0.5 ppm BAP and 6 ppm IAA, which was 6.33. The highest root length was found in the B0I4 treatment (BAP 0 + IAA 4 ppm). The results of the analysis of the interaction variance between the IAA treatment and the BAP treatment were 0.005, meaning that there was a significant effect of the combination of IAA and BAP on the leaf length of Cattleya sp.

Abstract

Menangkap ikan adalah mata pencarian yang ditekuni setiap hari oleh masyarakat pesisir pantai Katapiang Padang Pariaman Sumbar. Biasanya, nelayan menangkap ikan di tengah laut dan hasil tangkapan dibawa dengan perahu kedarat. Setelah perahu sampai dibibir pantai kemudian perahu yang berisi hasil tangkapan ikan di tarik ke darat bersama sama oleh kelompok nelayan secara manual menggunakan tenaga manusia. Proses tersebut menurut nelayan tidak efektif dan meminimalkan hasil tangkapan karena harus dibagi ke anggota penarik. Adapun tersedia alat penarik sederhana tetapi tidak layak pakai karena tidak terawat dengan baik. Tujuan pengabdian pada masyarakat ini adalah mengedukasi masyarakat tentang alat bantu penarik perahu melalui pelatihan singkat tentang alat penarik perahu, cara operasi dan perawatannya supaya alat dapat berfungsi dengan baik dan memiliki umur pakai yang lama. Metoda yang digunakan adalah metoda pelatihan langsung ke kelompok Nelayan mitra. Hasil yang didapat setelah pelatihan ini anggota kelompok nelayan mampu mengoperasikan alat penarik kapal dan mampu melakukan perawatan harian pada alat penarik perahu. Kata kunci: penarik perahu nelayan, alat bantu tarik, pelatihan pengoperasian mesin, nelayan, tangkapan ikan ABSTRACT Fishing is the daily livelihood of the coastal community in Katapiang, Padang Pariaman, West Sumatra. Typically, fishermen catch fish in the open sea and bring their catch to shore by boat. Once the boat reaches the beach, the fishermen manually pull the boat, filled with their catch, to shore together as a group. This manual process is considered inefficient by the fishermen, as it reduces their catch since it has to be divided among the pullers. Although there is a simple pulling device available, it is not in usable condition due to poor maintenance. The aim of this community service is to educate the community about the boat pulling device through a brief training session on its operation and maintenance, ensuring the device functions properly and has a longer lifespan. The method used is direct training for the partner fishermen group. The outcome of this training is that members of the fishermen group are able to operate the boat pulling device and perform daily maintenance on it.

Abstract

In previous studies, hybrid crash boxes have been developed because it show better energy absorption characteristics. Circular hybrid crash box combine the advantages of low-density of composite with stable deformation of metal provide a potential energy absorption device. Tests were carried out experimentally and iumerically under frontal load. This study aims to determine the energy absorption characteristics of two different configuration of hybrid material compositions using Aluminum Alloy 6063 and T300-epoxy Carbon Fiber composites. Present two typical configurational schemes, namely Al-Ko (i.e. a metal outer tube internally filled with an inner carbon fiber reinforced plastic (CFRP) tube) and Ko-Al (i.e. an outer composite tube internally filled with an inner metal tube). Composite layups arrangement with fiber orientation direction [0,90]10. First, the simulation models were developed and validated by comparing the damage modes and crashworthiness indictors with the dedicated experimental study. Second, the interactive effects of different configuration hybrid tubes were investigated by analyzing the discrepancies in the deformation pattern and internal energy absorption of each material through the validated simulation models. The test results show that the greatest energy absorption occurs in the Al-Ko model of 7401.4 J. This hybrid crash box has an energy absorption value of 11% greater compared to the sum of the energy absorption of aluminum tubes (3746.5 J) and composite tubes (2923.4 J).
