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%.

Abstract

Electricity is the main requirement for every activity held at the Asiyah Kindergarten school. The Aisyah Kindergarten School building, located in Muarajalai Village, has good electrical installations, but maintenance is rarely carried out. Maintenance of electrical installations is very necessary, because over time the condition of the feasibility of electrical installations really needs to be paid attention to. One effort that can be made to maintain electricity is to install extra security equipment to overcome electric current leaks. In general, homes or schools usually only use MCBs, MCBs only function for protection in the event of an overload or short circuit. However, electric current leakage cannot be protected by MCB. It is necessary to additionally install an ELCB to detect electric current leaks, so that if someone is electrocuted, the ELCB will be able to work in less than 0.1 second to cut off the electric current. Apart from protecting humans, ELCB can also protect equipment that uses electricity from electric current leaks.

Abstract

Electrical energy is a primary source of energy in daily life, with various electrical devices supporting human activities. Sometimes, electrical equipment experiences damage, with repair risks ranging from small to large scale. For damage with medium to large-scale risks, specialized experts are usually needed for repairs. However, damage to electrical installations with small-scale risks should be manageable by household members, especially housewives. Many housewives are afraid and do not understand how to handle electrical issues, even though they are active at home every day. Therefore, there is a need for training and counseling on simple electrical installations so that they can handle it confidently and safely. One form of training that can be provided is the creation of an electrical outlet set for PKK mothers in Muarajalai Village, Hamlet IV. This training aims to equip the PKK mothers with the skills and knowledge about tool specifications, tool functions, and safety procedures when using electrical equipment. With this training, it is hoped that they will be able to maintain and repair simple electrical installations at home without relying on experts, while also increasing their confidence and independence in handling everyday electrical problems.

Abstract

ChatGPT said: The processes of irrigation and fertilization in agriculture are time-consuming and physically demanding, as farmers typically irrigate twice daily and fertilize every three to four days. These repetitive tasks can lead to fatigue and reduced efficiency. To address this, we have developed an automated system for irrigation and fertilization that enables farmers to manage these activities remotely via smartphone. The system utilizes a microcontroller programmed based on specific agricultural needs and connected to the internet through Wi-Fi. This connectivity allows farmers to activate irrigation or fertilization with a single tap on their smartphones, anytime and from anywhere. The system aims to increase efficiency, reduce labor, and provide a more cost-effective and precise method of managing agricultural land. By automating routine tasks, farmers can better allocate their time and energy while ensuring optimal crop growth. The final outcome of this research is expected to be applicable directly in the field, allowing for real-world testing and refinement. Furthermore, the findings will be shared through a scientific publication to support knowledge.

Abstract

The use of Centrifuge Decanter as a waste treatment in industry has been widely used. Centrifuge Decanter separates waste in the form of a mixture of solids and liquids (slury) by utilizing the centrifugal force generated by the difference in the rotation of the tube (bowl) and screw conveyor. The rotation of the screw conveyor is reduced through a cycloidal gearbox. The shaft in the cycloid breaks during operation, for that it is necessary to conduct research to determine the cause of this shaft fracture. This research starts from a literature study that discusses the working mechanism of the decanter and the causes of the failure of the cycloidal gearbox shaft. For completeness of the analysis, data collection includes data on engine operation, physical and mechanical properties of the shaft material, fractography of the shaft and the stresses acting on the shaft. From the results of data analysis, it is known that the shaft has ductile fracture due to overload. The load that causes the shaft to break is the torsional load that comes from the rotation of the decanter tube at the initial start of the engine. Torque due to the rotation of the tube produces a shear stress that exceeds the yield stress of the shaft material plus a stress concentration factor in the fractured shaft fillet area.
