Ice tube is one of the most popular types of ice because it is more practical. Along with the shifting of people's needs from block ice to tube ice, the need for tube ice is increasing. To expand the big opportunities, we need ice tubes that can be made at home with small scale production. With a simple design and at a low cost. ice machine designed to use a vapor compression system. The main components consist of: compressor, condenser, capillary tube, and evaporator with refrigerant using R22. Considering that the tube ice machine is designed at home with a 12V DC pump as a water vacuum and sprays water into the evaporator with a water flow rate of 1.4 liters per minute. To determine the performance of the system with different water flow rates, performance testing was carried out on a tube ice machine with variations in the flow rate of spray water with several voltages, namely at 9 volts, 12 volts and 15 volts. From the tests that have been carried out, the results show that at a voltage of 9 volts it has the lowest efficiency of about 75%, with an evaporator temperature reaching -5.5°C and a condenser temperature of 46°C, at a voltage of 12 volts it has an efficiency of around 77%, with an evaporator temperature reaching -4.25°C and the condenser temperature is 43°C, while at 15 volts it has the highest efficiency of around 82%, with the evaporator temperature reaching -1.06°C and the condenser temperature 39°C. However, the operational cost rates for using an ice tube machine at a voltage of 9 volts, 12 volts and 15 volts are Rp. 634.56,- ; Rp. 765.85, - and Rp. 1223.07,- per kilogram of tube ice for 45 minutes on operational test.","PeriodicalId":165554,"journal":{"name":"Proceedings Series on Physical & Formal Sciences","volume":"251 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135804598","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 PLTS monitoring system is based on Arduino Uno so that monitoring on PLTS can be monitored with telegram media. The monitoring system has two inputs, namely for PV and for the battery. To monitor the value of the electrical energy parameter, the INA219 sensor is used. The sensor reading results are displayed on the 16x2 LCD and mobile phone by sending the \"STATUS\" message command to the ESP8266 wifi module. Retrieval of current and voltage data on INA219 sensor readings and standard measuring instruments is carried out every 5 minutes. The system can monitor via an Android smartphone using Telegram. The test results show that the Telegram application can display and monitor photovoltaic and batteries in real time. The average error during sensor monitoring at photovoltaic output is 0.16% for voltage and 1.25% for current. The sensor reading results have an average error when charging the battery of 1.36% for voltage and 2.04% for current. The characteristics of the results of this measurement meet the requirements of IEC standard no. 13B-23.","PeriodicalId":165554,"journal":{"name":"Proceedings Series on Physical & Formal Sciences","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135805267","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}

Here we use 4 types of exhaust, namely factory standard exhaust, slip-on exhaust (standard header-modified muffler), slip-on (modified header-standard muffler), and full system exhaust that we take from the market. This study aims to test the performance of the motor which consists of torque, power, and exhaust emissions (CO and HC levels) from the four types of exhausts, using a dynamometer to determine torque and power, an emission gas analyzer to determine the level of exhaust emissions (CO and HC). Our experimental results show the data, the results are still below the standards set by the Indonesian government. The greatest torque of 15.02 N.m at 7500 rpm and the greatest power of 18.36 hp is achieved by a full-system modified exhaust compared to the standard exhaust with the highest torque of 14.62 N.m at 7000 rpm and the highest power of 16.67 hp at 9500 rpm. The best exhaust emission levels are achieved by standard exhaust with the largest CO content of 0.62% at 10000 rpm and the largest HC content of 107 ppm at 10000 rpm compared to full system exhaust with the largest CO content of 1.79% at 10000 rpm and 201 ppm HC levels at 10000 rpm, in other words the standard exhaust is still more environmentally friendly than the full system exhaust.","PeriodicalId":165554,"journal":{"name":"Proceedings Series on Physical & Formal Sciences","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135804601","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}

This study was conducted on a lab scale with a capacity of 2 liters, using Al-Al electrodes with a voltage of 13 volts. The variables studied were EC time (20, 30, 40, 50, and 60 minutes) and electrode plate area (90 cm2 and 99 cm2) with a thickness of 1 mm. The parameters measured were COD and TSS of tofu wastewater before and after treatment. The results showed that the electrocoagulation and filtration methods with tamarind seed media could reduce the COD and TSS levels of tofu wastewater significantly. The optimal condition was achieved at EC time of 50 minutes and plate area of 99 cm2, with COD removal of 78.7% and TSS removal of 88%. This was due to the production of metal ions (Al3+) as destabilizing agents at the anode, the formation of flocs by protein and tannin in tamarind seeds, and the pH reduction by ascorbic acid and citric acid in tamarind seeds. This method had the advantage of not using synthetic chemicals and producing a more environmentally friendly final product.","PeriodicalId":165554,"journal":{"name":"Proceedings Series on Physical & Formal Sciences","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135805259","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 Leslie Matrix is ??one of the mathematical tools used to model the growth and changes in populations of living things, so that it can assist BPS in predicting population numbers and population growth rates at a time.
