Abstract

The sprocket and chain transmission system was used to transmit the rotating force that occurs between two shafts where they can reach it. The sprocket and chain transmission system transfers a movement from the driving source to the moved object. If the maintenance of the sprocket and chain transmission system is carried out only occasionally, the sprocket and chain may cause misalignment. That can affect the machine's performance and cause a breakdown of the machine's components. This study aims to determine the effect of misalignment on the electric current usage and shaft rotation speed in the sprocket and chain transmission system. The leading equipment used in this study is a sprocket and chain alignment kit, while the auxiliary equipment used are ampere meter, tachometer, and other equipment. Measurements of electric current and shaft rotational speed were carried out with a variation of misalignments. The study results show that the increase in the misalignment causes a higher electric current. As for the effect of misalignment on shaft rotational speed, the rise in the misalignment causes the post-rotational rate to lower.

Abstract

Shallots are vegetable commodities whose economic value and needs are quite high in the country, this has caused a decrease in the value of shallot exports over the last 5 years. Therefore, it is necessary to increase shallot production in order to increase the export value of shallots again by using Plant Growth Promoting Rhizobacteria (PGPR) biological fertilizers containing good microorganisms that can produce phytohormones, help increase soil fertility and reduce pests. The research was conducted in the experimental land of the Faculty of Agriculture, Winaya Mukti University, Sumedang Regency. The research implementation time is from February 2023 to August 2023. The purpose of this study was to determine the effect of growth and yield of onion plants and obtain the best dose of bamboo root PGPR on the yield of onion plants of the Bima Brebes variety. The environmental design uses Group Random Design (RAK) consisting of 5 treatments (A = 0 L ha-1, B = 2 L ha-1, C = 4 L ha-1, D = 6 L ha-1, E = 8 L ha-1) and repeated 5 times. The results showed that the dose of PGPR bamboo roots had a significant effect on the yield of onion plants of the Bima Brebes variety on the observation parameters of the number of tubers per clump, the number of tubers per plot and the fresh weight of tubers per clump. No dose of bamboo root PGPR gave the best results, but one dose of PGPR showed better results at a dose of 6 L Ha-1 on observation of the number of tubers per plot.Keywords: Shallot, Bima Brebes, Dose, PGPRShallots are vegetable commodities whose economic value and needs are quite high in the country, this has caused a decrease in the value of shallot exports over the last 5 years.

Abstract

The conventional process of printing meatballs using hands and spoons is considered less efficient in the production process both in quality and quantity. Meanwhile, commercially available meatball printing machines are bulky and complicated to use. Therefore, the design of a meatball making machine that has smaller dimensions can be developed at a more affordable price. This research began by designing a meatball printing machine using the SolidWorks software, with a frame design made of U-profile iron, meatball containers made of stainless steel cylinders, and packaging boxes for the electrical system from the relay. In the operation of the meatball molding machine, pneumatic is used as a drive system with a time delay relay to control the time for cutting the meatball dough. The manufacture of this machine produces a pneumatic-based meatball molding machine with constant pressure, with an automatic system using a time delay relay of 2 seconds for cutting forward and 0.2 seconds for cutting backward. From testing the machine applying a mass of 2.5 kg meatball dough, 192 meatballs were obtained, with a processing time of 7 minutes 29 seconds, with a remaining dough mass of 4 ounces, and an average meatball diameter of 24.95 mm.

Abstract

Porang plant tubers have the potential to have high economic value, because they contain glucomannan which is good for health and can be processed into a food source to replace carbohydrates. The aim of the study was to identify Karawang Local Porang strains using molecular markers and morphological characters as an effort to conserve and utilize Karawang's local biological resources. Exploration of Local Porang Karawang was carried out at the foot of Mount Sanggabuana which is the habitat of Porang in Karawang district. Molecular identification was carried out at BBPP Biotechnology and Agricultural Genetic Resources with comparisons of Porang Sidrat., Madiun 1 and SS1 Bulukumba varieties. Morphological identification was carried out at the Basic Laboratory of the Faculty of Agriculture, Winaya Mukti University. Based on the results of the DNA amplification of the Porang samples using four RAPD primers, it was found that the three primers showed differences in banding patterns between the Porang Karawang sample and the three Porang varieties for comparison (Porang Madiun 1 Sidrap and SS1 Bulukumba). This shows that there is genetic variation between Porang from Karawang and three other Porang. The results of genetic relationship analysis using four RAPD primers showed that the Porang Karawang sample was different from the Porang samples from the other two areas. The morphological identification results showed differences in characteristics with the comparison. The Karawang Local Porang variety has high quality as indicated by high glucomannan levels of 79.80%.
