Karakterisasi Kekuatan Bending Dan Hidrofobisitas Komposit Serat Kulit Waru (Hibiscus Tiliaceus) Kontinyu Bermatrik Pati Ubi Kayu

The development of biopolymer becomes alternative solution of the waste problem which is mostly produced by synthetic polymer. Biopolymer cassava extract which has big potency to be developed as synthetic polymer alternative. Nevertheless, the basic characteristic which is hydrofilyc and low tensile strength makes the polymer film produced not acceptable to be used as synthetic polymer alternative. The method used in this research was continous fiber biocomposite by pressed hand lay up. The matrix was Wau wood fiber which had layer variety 1,2,3,4 and the fiber directions 0o and 90o. The matrix biocomposite uses cassava extract with addition variation of gliserol 5%,10%,15% of dry weight. The experiment testing used bending test standart ASTM C 393 (1997) and moisture test standart ASTM D570-81. From this research, it was found that the highest bending result on fiber variation 3 layers and 5 % matrix gliserol was 50,58 Mpa. The highest elongation on 15% gliserol+1 layer was 35%. The lowest moisture test occurred on 1% laye and 5% matrix was 39.3%

Rancang bangun mesin pengupas tempurung kelapa

The first work that must be done on coconuts after the coir stripping process is to strip the coconut shells. This is because the part of the coconut that is processed further is part of the coconut meat itself. Coconut shell is the hardest part of the coconut fruit. On this coconut shell, coconut meat is attached. Manually removing coconut meat will take a relatively long time, around 3-5 minutes for 1 coconut. Of course, with this time the capacity and production efficiency cannot be maximized. This research was conducted with the aim of designing and testing the capabilities of coconut shell peeling machines. This machine is operated by using 2 blades, namely a flat peeler blade as a barrier to the surface of the coconut shell and a toothed peeler to press the surface of the shell. The results of the functional testing of this machine obtained the best value at the rotational speed of the peeler teeth of 14 rpm with an average shelling time of 20.96 seconds per piece.Keywords: coconut, machine, coconut shells, shelling time

Analisis panjang bidang kontak perontokan lada pada mesin perontok lada tipe silinder berjaring

The threshing process is one of the problems because currently is still mostly done manually. The development of a mechanical pepper threshing system has been carried out by making a pepper threshing machine. Further development is carried out by analyzing the mechanism of pepper threshing. Based on these problems, a research was conducted to analyze the length of the threshing contact area on the pepper threshing mechanism. The independent variable of the research is the length of the threshing contact area. The dependent variables were threshing capacity, threshing efficiency and damage percentage of pepper. The length of the threshing contact area was varied namely 2, 4, 6 and 8 cm. The threshing mechanism rotational speed used is 360 rpm. The tensile strength of the spring on the threshing net is 0,22 kg/cm. The amount of pepper processed in 1 test is 0,4 kg. Based on the test result, the length of the threshing contact area is inversely proportional to the threshing capacity, and directly proportional to the treshing efficiency and the percentage of damage. The highest capacity and the smallest damage percentage were obtained at a contact area length of 2 cm, respectively 109,09 kg/hour and 10,85%. The highest threshing efficiency was obtained at a contact area length of 8 cm is 95,09%

The effect of dietary protein levels on body weight gain, carcass production, nitrogen emission, and efficiency of productions related to emissions in thin-tailed lambs

Aim: This study was aimed to evaluate dietary crude protein (CP) level on performance of body weight (BW) gain, carcass production, and nitrogen emission on lambs. Materials and Methods: A total of 12 male thin-tailed lambs (15.2±1.8 kg initial BW and aged 3-4 months) were assigned to completely randomized design for 84-day feeding trial. The animals were divided into three different levels of CP (i.e., 14%, 16%, and 18% with isocaloric diets and 60% total digestible nutrients) with four replications. Results: Increasing CP level was not significantly affected on average daily gain (ADG), carcass production, N and N2 O emissions, and efficiency of emissions related to the productions. The average of ADG, carcass production, meat production, meat protein production, N emission, and N2 O emission was 141.4 g, 11.6 kg, 6.8 kg, 0.9 kg, 53.1 g/day, and 0.3 g/day, respectively. The efficiency of ADG, carcass production, meat production, and meat protein related to N emissions were 119.7 g/kg, 4.4 g/kg, 2.5 g/kg, and 56.6 g/kg, respectively, while N2 O emissions related to ADG, carcass production, meat production, and meat protein were 2.4 g/kg, 0.027 g/kg, 0.36 g/kg, and 0.34 g/kg, respectively. Conclusion: It can be concluded that the increase of CP level up to 18% did not affect productivity, N emissions, and efficiency of emissions per unit product because the increase of CP was not balanced by energy content in feed

Penerapan Teknologi Mesin Pencacah Rumput untuk Kelompok At Taqwa Farm di Desa Sekura

The partner in this program is the At Taqwa Farm group, Sekura Village. The focus of the At Taqwa Farm group is agriculture and animal husbandry. This group has been established since 2020, and has 55 goat farming. The main problem faced by partners is in the feeding process. So far, partners have provided food by taking grass or leaves with a scythe, then simply giving it to livestock. Based on the partner's problems, the service implementation team provided a solution in the form of applying technology using an animal feed chopper machine to the partners. The stages of service activities include chopping machine design, chopping machine manufacturing, chopping machine performance testing, training on operation and maintenance of chopping machines, as well as handing over chopping machines to partners. The grass chopper machine handed over to the partner can function well in chopping grass for animal feed. This really helps partners increase their grass chopping capacity, making the feed preparation process easier for partners
