However, the problem thatusually occurs is that the number of service requests is not certain which results in raw materials that sometimesaccumulate or run out every month, errors in predicting the sales turnover of shoe washing services can result inowners experiencing losses if the target raw materials are not appropriate.This study aims to create a forecasting system for the amount of turnover from each service sale by Kinclong Sub usingthe Double Exponential Smoothing method, so that the raw material needs needed every month can be optimal. Thebest turnover forecasting results for each service on Kinclong Sub for the following month, May 2022, were Rp.10.006,248 with a MAPE value of 17.86% for DeepClean services. And Unyellowing got Rp. 1493,374 with a MAPEvalue of 17.18 %. So it can be concluded that the service that has the most turnover for the next month is DeepClean,the forecasting results can make it easier for Kinchlong Sub shop owners to provide raw materials from services thatare most in demand by consumers.","PeriodicalId":273708,"journal":{"name":"JEECS (Journal of Electrical Engineering and Computer Sciences)","volume":"43 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132969595","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 process of selling sacrificial animalsis still done traditionally by ordering directly by phone and coming directly to the cattle pen for the sacrificial animalsdesired by consumers. To deal with these problems, an alternative solution is needed that can create a informationsystem solution as a medium for selling livestock online. This online sacrificial animals buying and selling applicationwill be developed using the SCRUM method. When conditions change like this during the Covid-19 pandemic, SCRUMis suitable for developing applications. This is because Scrum is an iterative method that is included in the Agilemethod in how to manage and run an application development project. The features or menus that will be built in thisapplication including Master Data Management, and get Reports on all Transactions periodically, Shipping / DeliveryTransactions, notifications for Animal Husbandry Services. However, due to the conditions of the Covid-19 pandemic,there are several features that will be added, namely the Results of Routine Examination of the Condition of SacrificialAnimals for the last 1 month which will continue to be updated by livestock owners, and Description of PhysicalCondition of Sacrificial Animals which includes Species, Skin Color, Weight (Kg ), Height (cm). The results of theBlack Box Testing show that all functions have run well with a percentage of successful functional running of 97.3%.Keywords: Application, Online Buying and Selling, Sacrificial Animals, Scrum Method.","PeriodicalId":273708,"journal":{"name":"JEECS (Journal of Electrical Engineering and Computer Sciences)","volume":"33 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120810663","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}

In addition, voltage stability is very necessary in the continuity of the use of power plants. Unstable voltage and frequency make electrical equipment (load) easily damaged. There are various ways to reduce instability, one of which is using a pseudo/complementary load electronic control circuit. The point is that the generator will be loaded with a total load that is always constant, the load on the consumer plus the complementary (pseudo) load is equal to the nominal capacity of the generator. This research uses a 3 phase generator and a 3 phase induction motor as a driving machine, the main load uses a lamp and the pseudo load uses a heater. The main control uses a Dspic30f4012 microcontroller connected to a voltage sensor. The microcontroller works using PWM with feedback using PID, which then PWM provides pulse information to the load drive circuit. The use of PID in this control system will produce a voltage in the generator at 50 Hz and 220Vac whether there is a load or not. So that the voltage supplied to consumers is stable and does not damage electronic equipment.","PeriodicalId":273708,"journal":{"name":"JEECS (Journal of Electrical Engineering and Computer Sciences)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133453106","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}

Farming requires a largearea and fertile soil. With the development of agricultural technology today, there is a new method of planting calledHydroponics. There are several types of hydroponic systems, namely Aeroponics (fog system) and Nutrient FilmTechnique (NFT). In this article, the writer uses NFT technique. NFT is a system that has a farming concept bychanneling nutrients to plant roots in a film or thin so that plants get food nutrients, namely water and oxygen. Theadvantage of using this NFT system is that it makes it easier to control plant nutrients and plant growth is fasterbecause plant roots are free to absorb nutrients to the maximum. From the results of the research conducted, the pHsetpoint value was 6.0. From the results of the research conducted, set point pH values of 6.4 and 5.8. From the testresults, the Ziegler Nichols method of type 1 for a setpoint of 6.4 gets a value of L=3 and T=22.44 and a setpoint valueof 5.8 gets a value of L = 3 and T = 23.76. After that, the setpoint 6.4 got the value of Kp = 8.976 Ki = 1.496 Kd =13,464 and the setpoint of 5.8 got the value of Kp = 9.504 Ki = 1.584 Kd = 14,256. 1.

Nahdhotul Ulama (NU) is one of the socio-religiousorganizations in Indonesia which was founded on 16 Rajab 1344 or to coincide with January 31, 1926 in Surabaya onthe initiative of two leading traditional scholars at that time, K.H Hasyim Asy'ari and K.H Abdul Wahab Hasbullah.Geographic Information System is a computer system that is used to collect, check, integrate, and analyze informationrelated to the earth's surface. Basically, the term geographic information system is a combination of three mainelements, namely system, information, and geography. Thus, an understanding of these three main elements will bevery helpful in understanding GIS.
