Like agriculture, livestock is also a growing business that can help local farmers to generate their income. Thus, an economic and practical chopper machine for livestock feed is necessary to fulfil this demand. The machine is driven by an AC powered motor (1400 rpm, 1 Hp). It is divided into five major components, which are the fodder inlet, fodder outlet, power unit, cutting unit and frame stand. For safety reason, a cover made by clear acrylic Perspex were built in front of the blade to prevent any injuries. The machine structure is reasonable and practical as it is supported by four lockable wheels and handle for easy movement. Time taken to finish the chopping process will be analyzed for both methods. Three different weights of fodder will be used. For 500g, 1000g and 1500g of weight, average production time taken by machine is 15s, 33s and 42s respectively. While conventional method is 240s, 400s and 640s respectively. The percentage decrease of production time was calculated to evaluate the performance. Based on the result obtained, it shows that by using the chopper machine, it can help to reduce the production time to produce the chopped fodder compared to the conventional method. For weight 500g, it reduces the production time to 93.75%, for weight 1000g to 91.75% and lastly for weight 1500g to 93.44%. Hence, the chopper machine is practical, flexible and cost effective to use for chopping fodder.","PeriodicalId":7884,"journal":{"name":"Andalasian International Journal of Applied Science, Engineering and Technology","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87094242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this project was to invent a cooler box that is suitable for outdoor activities. The thermal conductivity which is to measure the ability of the material to conduct heat in each layer inside the thermoelectric cooler box was identified for heat transfer analysis. Thermoelectric cooler box can be operated with a 12V battery or 12V DC power supply. The battery power can be charged using a 20W solar panel (if the battery power is drained out), with the condition that there should be heat radiation to generate electricity. Thus, no additional cost is needed on ice cubes whereby previously it requires more ice cubes to maintain the cold temperature inside the cooler box. By using a Peltier plate, the cooling hours inside can reach up to 100,000 hours with a maximum of 12 can of beverages stored inside the cooling box. Based on literature reviews, conduction and convection resistance between each layer of materials inside the cooler box play an important role to ensure heat is transferred inside the box. The heat sink also helps to ensure heat dissipation before flowing into the cooler box. In this design, a total of 56 kW of heat can be transferred from the box to keep the cooler box cool with the minimum temperature 15.6°C within a period of 35 minutes.","PeriodicalId":7884,"journal":{"name":"Andalasian International Journal of Applied Science, Engineering and Technology","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81596271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system serves the drinking water in Banjarsari Villages. This study aims to optimize the pressure of the water distribution network in the Banjarsari Villages. This system supplies water from the Banjarsari water treatment plant. The water distribution network uses the gravity method to deliver water to customers. The drinking water distribution network was obtained from PDAM Bojonegoro. Meanwhile, the elevation and node of pipe were obtained by using Google Earth. Before optimization, the water distribution network has negative pressure at 07.00 AM and 05.00 PM. The negative pressure zone is at the end of the distribution network. The negative pressure values obtained using EPANET is range from -0,67 meters to -6,34 meters. The water distribution network is optimized by replacing diameter pipe in some areas, the water pressure increases significantly and makes the water distribution has positive pressure values. The pressure values are range from 2,70 meters to 13,65 meters. Replacing diameters of pipe is a solution to remove negative pressure, so that water from the reservoir can deliver to the end of a pipe. The distribution network pipe diameter is chosen which is close to the calculated pipe diameter.","PeriodicalId":7884,"journal":{"name":"Andalasian International Journal of Applied Science, Engineering and Technology","volume":"81 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77200788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To maintain the quality of electrical energy, there are several parameters that must be considered in the distribution network, including voltage drop, power losses, power factor and other factors. One of the solutions used to improve the voltage drop and power factor is to install a capacitor bank in the distribution network. This paper will discuss the placement of capacitor banks using the fuzzy logic method with inputs in the form of voltage profiles, power losses and power flow calculations using ETAP 12.6.0 software. In the Rao feeder, the final voltage is 16.806 kV or has passed the standard set by PLN (-10% and +5%). The Rao feeder has a power loss of 0.242 MW and a power factor of 0.7815. Fuzzy logic method is used to determine the optimal location of capacitor placement. After the installation of the capacitor bank, the terminal voltage increases and the total power loss decreases, while the power factor increases. From the results obtained, PLN as a supplier of electrical energy can reduce power losses by placing and installing capacitor banks in the distribution network.","PeriodicalId":7884,"journal":{"name":"Andalasian International Journal of Applied Science, Engineering and Technology","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80343787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The production of machines to help simplify the process of removing chicken feathers is seen as a necessity for these small and medium industrial entrepreneurs. This is why we focus on producing chicken feather retractor machines (CFRM) that are capable of processing up to five chickens at once. This machine is portable and easy to move around and supported by four wheels that can be locked to ensure stability. This machine can perform effectively to remove feathers using friction concept between the chicken and the plucker fingers rubber which attached around the drum. The machine also environmentally friendly by filtering the feather from scattered everywhere and only allow water to come out. The result shows that this machine operates under the motor powered with 115.13 rpm with the rotating plate area is 0.166 m2 and drum volume of 0.158 m3.
