There are many methods springing up in its use. One of them is the Convolutional Neural Network (CNN) as used in this research. The method is used to detect image patterns from the shape of the arrangement of the fingers of one hand as a signal from the identification of the numbers 0 to 9 in SIBI (Indonesian Sign Language System). The problem of the research is that many optimizers emerge in a deep learning method. Therefore, selecting the right optimizer itself is a challenge that can be used as the next reference for input images that do not go through the previous pre-processing stage. The aim of the research is to get the best accuracy score from the comparison of 3 optimizers and their relations to processing time. The conclusion obtained shows that AdaDelta optimizer that has existed for a long time can provide better results than Adam which is the development of the last optimizer.","PeriodicalId":177991,"journal":{"name":"STRING (Satuan Tulisan Riset dan Inovasi Teknologi)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130201206","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 the production process at PT X in August 2022, there is a problem related to the level of defects in the cap flip top ∅ 50-8 white snap products which increases and exceeds the regulatory limit (5%), reaching 10% or 65,707 units of the total production of 658,000 units. Based on the problem of the high percentage of defects, it is necessary to carry out a quality control using six sigma to determine the level of defects that occur, to look for factors affecting the highest defects and to provide suggestions for improvements. From the results of the analysis using six sigma, it is found that the highest level of defects, namely the type of black spot defects, is 45,413 pcs with a percentage of 69.11% and the average sigma value obtained is 3,022. Next, the results of the fishbone diagram analysis show that the factors causing black spot defects are machines, materials, humans, media, and methods. From each of these causal factors, improvement can be given using 5W + 1H to reduce black spot defects that occur in the cap flip top ∅ 50-8 white snap on in the next production process.","PeriodicalId":177991,"journal":{"name":"STRING (Satuan Tulisan Riset dan Inovasi Teknologi)","volume":"192 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116521876","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}

A monitoring system on chili plants designed in the form of the Internet of Things (IoT) is an electronic device that can interact directly with users who use it for monitoring and controlling devices with the help of the internet. The creation of the chili plant monitoring based on the Internet of Things (IoT) can facilitate monitoring activities on chili plants to monitor temperature, humidity and light intensity in real time without having to come to the location of chili planters. This study uses quantitative descriptive research by describing the design of a prototype monitoring system for temperature, humidity and light intensity on chili plants based on IoT and describing the results of measuring temperature, humidity and light intensity on the prototype that has been made by researchers. The results of this prototype design have the main components, namely NodeMCU ESP8266, DHT 22 Sensor and BH1750 Sensor. The results obtained for measuring temperature, humidity and light intensity in this prototype show that the R square value on the DHT sensor for temperature and humidity is 0.949 and 0.870 while for the BH1750 sensor value for light intensity is 0.998. The R square value of the sensor is in the interval 0.80-1.00. The results of the calibration measurement carried out on this prototype are considered very valid. Field test results show the sensors and outputs obtained can function very well.","PeriodicalId":177991,"journal":{"name":"STRING (Satuan Tulisan Riset dan Inovasi Teknologi)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115056348","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}
