An interesting commodity to watch out for in the oil and gas industry is liquefied petroleum gas (LPG). LPG is a hydrocarbon gas that has been liquefied under pressure to facilitate storage, transportation, and handling and the main ingredients consist of propane/C3, butane/C4 or can be mixed to produce mixed LPG..At this time PT. BLORA MUSTIKA does not focus on when household needs increase and when not, the meaning of this is that LPG gas data is not used properly and is only recorded, this of course makes PT BLORA MUSTIKA unable to predict demand from sub-distributors and results in frequent an empty supply of LPG gas causing difficulties for the community to obtain 3 Kg LPG gas. This problem can be calculated and compared with the Multiple Linear Regression and K-Means methods.By using the Multiple Linear Regression and K-Means method, it is hoped that it will make it easier for PT. BLORA MUSTIKA in determining demand predictions from sub-distributors so that there is no shortage of LPG gas supplies and which method can be obtained which is more effective and efficient.","PeriodicalId":32029,"journal":{"name":"Proxies Jurnal Informatika","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88802651","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}

Untuk memiliki kendaraan roda empat yang sesuai dengan kebutuhan pengguna, pengguna cenderung membanding-bandingkan beberapa hal dari kendaraan satu dengan kendaraan lainnya seperti  harga kendaraan, efisiensi keiritan bahan bakar, fitur kendaraan, kehandalan mesin, dan juga tipe kendaraan tersebut. Untuk mengatasi permasalahan itu pengguna dapat membandingkan langsung hal-hal tersebut agar nantinya pengguna tidak mengalami kebingungan dalam memilih kendaraan. Metode yang dapat digunakan untuk menentukan kendaraan roda empat yang sesuai dengan kebutuhan dan budjet masyarakat yakni salah satunya dengan menggunakan metode Analityc Hierarchy Process (AHP). Metode AHP merupakan metode sistem pengambil keputusan yang menggunakan tingkatan hierarcy dalam mengatasi permasalahan yang kompleks yang membutuhkan keakuratan dan keefiensi dalam merencanakannya. Berdasarkan hasil pengujian metode menunjukan hasil yang signifikan, dalam hal ini Honda Brio lah yang paling layak untuk digunakan oleh masyarakat.","PeriodicalId":32029,"journal":{"name":"Proxies Jurnal Informatika","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86956047","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}

One of them is controlling and monitoring dangerous air pollution and if it is inhaled directly by humans in large enough quantities it will cause health problems in respiratory function. There are various kinds of air pollution, such as CO and CO2 which are found in burning cigarettes or other burning which is carried out every day in households. In addition to hazardous substances, to support a complete smarthome-based research, it is also necessary to add a sensor to detect fires and gas leaks in households. This study aims to design and manufacture a room pollution detector using the MQ-2, MQ-6 and Flame Sensor sensors to detect air pollution caused by CO and CO2 and detect LPG gas leaks and detect fires with notifications via led matrix and based alarms. arduino . The results of this study indicate that to design and manufacture pollution detectors using a smoke sensor that uses Arduino Uno as a microcontroller that controls the work of the system connected to the MQ-2 sensor used to detect smoke, the MQ-6 sensor to detect LPG gas, and to detect fire use Flame. Sensor (Fire Sensor) DFR0076. From the results obtained by the MQ2 smoke sensor, the resistance value of the sensor will decrease when smoke is given, otherwise the sensor resistance value will increase when smoke is not given. The sensor resistance ranges from 150 Ω – 300 Ω when smoked and 1.5 KΩ to 1.7 KΩ when not smoked. gas sensor resistance increases when given gas and decreases when it does not detect gas. The sensor resistance when reading the presence of gas in the air is between 100 Ω - 400 Ω, and when it does not detect gas, it is 0 Ω - 12 Ω. On the Flame sensor, the sensor voltage value changes when it detects fire. The voltage value increases if it detects fire and vice versa the sensor voltage decreases when it does not detect fire. The sensor voltage value when detecting fire is between 1.2 Volts – 5 Volts, while when it does not detect fire, it is between 0 Volts – 0.9 Volts.","PeriodicalId":32029,"journal":{"name":"Proxies Jurnal Informatika","volume":"161 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86177248","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}
