In Indonesia, especially in the province of Riau, the majority of landowners for oil palm plantations do not directly work on their own oil palm plantations, but instead the landowners trust other people to work on their plantations, so that landowners cannot directly know or monitor the mass data of their palm fruit weighing. . So this research designed an Internet of Things (IoT)-based digital palm fruit weighing device to make it easier for landowners to know or remotely monitor the mass data of their palm fruit weighing. This system is designed using TTGO T.Call ESP32 as system control and load cell sensor as a detector of oil palm fruit mass. The average percentage accuracy value of the tool reads the mass data of weighing palm fruit using the same load, which is 98.03% of 10 tests. Meanwhile, when using varying loads, the average accuracy percentage value is 99.28% from 18 tests. With this tool, the mass data of oil palm fruit weighing can be monitored remotely and in real time by plantation land owners.","PeriodicalId":308479,"journal":{"name":"Jurnal Elektro dan Mesin Terapan (ELEMENTER)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129156277","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 conventional fence is opened and closed manually by the home owner. In rainy conditions this will be very ineffective and inefficient because the home owner has to get out of the vehicle to open the fence. This problem underlies the idea of making an automatic fence opening and closing system using a smartphone by utilizing Internet of Things (IoT) technology. Smartphone is useful as a NodeMCU controller contained in the ESP8266 WiFi module via an internet connection to connect to the blynk application. Relay is used as a switch that will command the motor to rotate when it gets a command from NodeMCU. Changes in relay conditions will cause the 12volt 200rpm DC motor to rotate, so the fence will move opened and closed. The movement of the servo motor also causes the turnstile to lock after the fence is closed. In order for the system to work properly, the revolutions per minute (RPM) of the motor requires a supply voltage of 12V. When the fence is opened, the motor speed is 53RPM. When closed, the motor speed is 49RPM. In the process of locking and opening the fence, the servo motor takes about 2 seconds.","PeriodicalId":308479,"journal":{"name":"Jurnal Elektro dan Mesin Terapan (ELEMENTER)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126373412","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 squeezer rolls were driven by 1-phase motor with fixed speed by the gear ratio setting. The distance and position between the rolls are arranged in such a way that the pressing power is maximized, but it is maintained to avoid stuck. The peeled and cut sugarcane is loaded into the hopper. Then, the sugar cane is drawned and squeezed by rolls. After that, it filtered and stored in the container. This machine is equipped with an automatic system for dispensing sugarcane juice from the container to the glass.

In Indonesia, there is a tool that functions to convert solar energy into electrical energy called photovoltaic. The research uses monocrystalline solar panels because they are the most efficient and produce the highest electrical power per unit area. This research aims to analyze the comparison of solar cells, which are arranged in series and parallel to the output power. Researchers made direct observations of the field and studied after getting some data from the measurement results. Then conclude from the results of this observation. Sampling was researched on the output of solar panels located at BBPLK Serang. The method used is the comparative analysis method, by comparing the differences and similarities of an event. The voltage and currently issued by a series of solar panels is 35.77V and 3.18A. The results of the voltage and presently published by a parallel series of solar panels are 17,69V and 6.38 A. The power is produced by a series circuit of 113.75atts and a parallel circuit of 112,86Watts. From the output power results, the series circuit is 0,89Watts greater than the parallel circuit. Judging from the advantages and disadvantages, it is better to install PLTS Off-Grid installations in parallel.

The World Bank estimates that the 2015 fire crisis cost Indonesia US$16 billion in forestry, agriculture, tourism and other industries. The smog causes respiratory and other illnesses in hundreds of thousands of people across the region. So far, efforts to mitigate forest and land fires have often been carried out by the government and the forest fire task force, starting from creating an early warning system, increasing community participation, and forest fire control techniques. However, all of these mitigation efforts are more dominantly carried out after forest and land fires have occurred. Whereas when a fire has occurred and the fire has grown bigger, fire mitigation efforts become more difficult and expensive because they have to involve helicopters to extinguish the fire from the air. So a land and fire mitigation effort requires one that is easy to use, fast and cheap to implement, and can reach a wider area than a forest area. The research aims to create a surveillance sensing system for forest fire for forest fire mitigation based on drone technology, and sensor technology. This research is an innovation and development of science and technology that is beneficial to the community, the forest fire task force and the local government. The research stages start from the design, manufacture, and design of a surveillance sensing system for forest fire in the Telecommunication Network laboratory. The output of this research is a prototype surveillance sensing system for forest fire. Test results within a certain time span indicate that the sensor is running well. All sensors used will show a change in value when a heat source and fire are detected. The average temperature sensor result is 72.34 C. While the dust particle sensor result is 665.45 g/m3 .

This is certainly very detrimental to the community and PLN. Voltage Loss Detector is designed to detect loss/ready voltage on branching transformers. This tool uses a ZMPT101B voltage sensor to detect voltage, an Arduino uno microcontroller and a GSM SIM800L module to send messages.

Sensor data is sent from Arduino to the data base server to be displayed on the website. The test results of each sensor compared to BMKG data showed small measurement error results for temperature and rainfall parameters with error percentages of 4.61% and 9.95% respectively. The results of measuring wind speed parameters have a considerable error of 30.03% caused by wind speed measurements carried out at different altitudes to BMKG sensors. Measurements of wind direction show different wind direction frequencies because they do not set the same reference point as the BMKG sensor at the time of the sensor laying. The PM2.5 measurement also showed a considerable measurement error result of 14.7% because the laying of the sensor was not conditioned with standards as in the BMKG sensor so that the particulate sample measured was not the same as the BMKG sensor. For measurement of sun radiation intensity and humidity each has shown a trend that is in accordance with environmental conditions.
