One of the plants used in hydroponic techniques is thepakcoy vegetable plant. Pakcoy is one of the vegetables that has the widest distribution in Asia.In addition, the characteristics of pakcoy vegetables are almost the same as mustard greens.Pakcoy vegetables are also easy to cultivate because they only require a small amount of landand a short harvest period. This system is built using a microcontroller and computer visiontechniques as a control center and uses a Raspberry Pi 4 type B mini PC as a visual notificationand is equipped with a dc motor gearbox, L298N motor driver and webcam camera. Thissystem works automatically to control which plants are healthy and which plants are sick. Thisstudy aims to detect diseased plants and healthy plants on pakcoy plants with a hydroponicpakcoy plant monitoring tool that uses a microcontroller and computer vision techniques. Thistool works by taking pictures directly through a webcam camera, then processing them with atrained model. The output of this tool displays the probability value of pakcoy plants showinghealthy plants and sick plants. From the results of testing the validation data using 60 validationdata, based on the accuracy of the detection tool healthy and sick plants were able to correctlyidentify 38 validation data and 22 data were not recognized properly, so the accuracy of thevalue was 63%. and produces an f1-score of 0,87","PeriodicalId":30870,"journal":{"name":"Jurnal Ilmiah Spektrum","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80710028","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 this study, the energy audit wasconducted at PT. Graha Sarana Duta II Denpasar which is located on Jl. Serma Gede No. 13,Dauh Puri Klod, Denpasar. Based on the existing conditions, the level of Energy ConsumptionIntensity (IKE) obtained before the audit was carried out was 245.22 kWh/m2/year or 20.43kWh/m2/month which according to ESDM No. 13/2012, Air-conditioned buildings are in thewasteful category. In this study, the energy audit focuses on the lighting system and airconditioning system. The method used in this research is to calculate and analyze theconsumption of electrical energy in the lighting system and air conditioning system. After doingthe research, it can be seen the energy saving opportunities (PHE) in PT. Graha Sarana Duta IIDenpasar by replacing the TL and SL lamps using LED lamps and requiring room users to turnoff the air conditioner when the room is not in use, the result is savings 11,4% in electricalenergy use, where the IKE after the audit is 18.1 kWh/m2/month. The office can also save thecost of using electrical energy, which is Rp. 3,170,394,- every month.","PeriodicalId":30870,"journal":{"name":"Jurnal Ilmiah Spektrum","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87590226","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}

Billboards containing text or images ofinformation promoting a product are usually taken by the advertising agency. Advertisingcompanies promote curated billboards using individual websites, requiring clients to switchbetween sites to get billboards that meet the criteria. The purpose of marketplace creation is toavoid customers having to switch sites for billboards that meet the criteria. The marketplace isbuilt using Laravel 7 framework with additional features of a business intelligence system tohelp customers get billboards based on their criteria. The decision support system uses aweighted accumulation method that uses multiplication to relate the scoring criteria, where thescore of each criterion will be increased by the weight of the related criteria. The use of adecision support system with a weighted product approach as a support function on a marketsite is the use of a decision support system as a recommendation for the application market.The result of this research is that a web-based marketplace with a decision support system hasbeen successfully built using the Laravel 7 framework and MySQL DBMS.
