As a country located among three major tectonic plate confluences, namely the Eurasian Plate, the Indo-Australian Plate, and the Pacific Plate, Indonesia is an earthquake-prone area. Information about the earthquake occurrences is distributed by the BMKG through social media, websites and television. However, it is undeniable that there are still people who do not have televisions or smartphones. Therefore, earthquake warning systems began to be widely developed. Furthermore, sensors for earthquake vibration detection have an important role in earthquake warning systems. So in this article, the author has conducted a literature study and analysis of the sensors commonly used in earthquake detection systems. This study aimed to present sensor recommendations to be used as earthquake sensors. The result of the literature study, that the author had done, is the selection of sensors is customized to the needs and budget of the project. A description of the sensor recommendations for each project has also been included in this article.

The increasing population and the growth of the industrial world, offices, hotels, and modern markets must be directly proportional to Indonesia's availability of electrical energy. The availability of sufficient electrical energy can affect the quality of life of the people and foster investor confidence in our country. Studies on the prediction (estimation) of peak electrical loads in electricity in Indonesia can be carried out using the Artificial Neural Network (ANN) method. The estimation of electricity load for the next 5 years is strongly influenced by several parameters, including population growth and peak load data of 150 kV GITET, Kesugihan Cilacap. This study took population data and peak load data at GITET 150 KV Kesugihan Cilacap in the past 5 years. The data used in this study were actual data, starting from 2015 to 2019. To display the results of the estimated electrical load on the 150 kV GITET transformer, the authors used the artificial neural network method. The peak electrical loads estimation results using artificial neural networks for electricity loads in the next 5 years, to wit from 2020 - 2024. The estimated peak load in Lomanis District is20.0311 MW, 24.443 MW, 19.9707 MW, 19.9705 MW and 19, 9705 MW. In Gombong District, the estimated peak load is 57,398 MW, 57,472 MW, 57,476 MW, 57,474 MW, and 57,479 MW.

In general, Radar or Radio Detection and Ranging is an electromagnetic wave system that is useful to measure distance and answer and make maps of surrounding objects. Radar has an advantage compared to other navigation tools, which is that radar does not require a transmitter station as a transmitter. Radar has an electronic wave emission principle that emits short radio wave pulses emitted in a narrow beam by a directional antenna. In this study, a multi-object radar detection simulation was carried out using Dopler processing both MTI and PDP, which later on the radar will detect related objects. Multi-object here is a condition that is achieved when a navigation radar detects more than one object. The result of this research is a multi-object detection process using the MTI and PDP methods and the matched-filter obtained from the predetermined data. So Doppler processing aims to mitigate the clutter signal to improve the detection performance of moving targets even though there is a dominance of signals originating from stationary clutter.

Lake Toba is a tecto-volcanic lake located in North Sumatra Province, Indonesia. Currently, Lake Toba is 1 (one) of 5 (five) Super Priority Tourism Destinations (DPSP) prepared by the Government of Indonesia. This study made a design for a water level monitoring system in the Lake Toba region. This system design is one form of mitigation, namely an effort to reduce disaster risk. The design of the Water Level Monitoring System in the Lake Toba Region used several components, namely Data Loggers, Sensors, and supporting equipment such as power supplies and communication systems. The Water Level Monitoring System in the Lake Toba Region was built in 6 (six) locations, namely Ajibata Port, Ambarita Port, Simanindo Port, Muara Port, Sippingan Port, and Balige Port. The observation of the monitoring system in the Lake Toba region showed that the water level and data quality vary. The sensor in this system can identify changes in water level in the Lake Toba region with a small amplitude of 10-15 centimeters.

A global positioning system (GPS) is often used as a tool for determining direction and positioning. However, GPS is weak in estimating the error, which is quite large at the actual distance, so positioning in a narrow area cannot work well. Therefore, a better method is needed to be used as a narrow-navigation system. This study aimed to determine whether RSSI has a better error than GPS for navigation devices in a narrow space or area. The method used was plotting graphs using Ms. Excel and determining the value of R square. The RSSI value was obtained through the Esp8266 device and then sent to the server via the MQTT protocol and converted using Node-Red on the Raspberry Pi. The comparison results of the Esp8266 device RSSI graph match the Laptop RSSI device as a reference. The match between the relative distance to the RSSI with the actual distance shows a 3.3-33% error. This result is considered much better than the GPS error.

Sorosutan is one of the villages in the Umbulharjo District with the largest population of 14,979 people based on statistical data in 2017. During the Covid-19 pandemic, the implementation of health protocols such as providing a handwashing area and mandatory wearing of masks is applied in all places, including public service places such as the Sorosutan Village Office. Socialization continues to be carried out by various parties so that residents can increase their self-discipline in every place and time, including when visiting these public places. The presence of officers or guards at each entrance is significant to remind residents who will enter. A large number of visitors will cause problems because it can cause long queues. In addition, the limited number of employees or personnel becomes a separate obstacle when it comes to preparing special personnel for controlling visitors. The smart sink is a solution in helping officers at the Sorosutan Village office remind residents to always wash their hands and wear masks when visiting the office. The temperature sensor installed in the sink can also help speed up temperature checking, which previously had to be done manually by officers. With the provision of this tool, it is hoped to increase public awareness so that the spread of Covid-19 can be reduced.

Floods and their problems show an increasing indication when rainfall is high. Data from BNPB shows that floods, landslides and tornadoes contributed to the total disasters in Indonesia in a decade. The existence of an early warning flood disaster can help evacuate before a disaster strikes. The system requires a water level detector as the basic data for determining flood predictions. In order to get the water level value, a touch water method can be used using electrodes or without touching the water with the help of pressure sensors, ultrasonic and imaging. Each method has advantages over the other. In this study, the effectivity and accuracy of detecting water levels were investigated using 3 methods: the direct touch of water through nickel wire, buoys with encoder, and pressure sensors. Detection of water levels can be used as a reference to obtain river water level data which is then connected via an IoT or internet connection as a reference for the Early Warning System for the arrival of floods. This study found that changes in water level of less than 30 cm can utilize buoys and encoders with an accuracy of detecting 5 to 6 counts per 1 mm increase in water level. Meanwhile, the measurement of less than 30 cm water level using nickel wire resulted in a non-linear value. The utilization of nickel wire can be used for a height of more than 30 cm where the change in resistivity has started to be linear. ADC change value is 2.93 mV/cm using 10 bit ADC at 5 Volt reference voltage. For water level heights of 50 cm and above, a pressure sensor can use a pressure sensor that can detect changes in pressure of 0.002 in Hg/mm or 0.05 mmHg/mm.

The work process in the washing division of the "X" Company consists of three kinds of processes: washing, squeezing and drying. All of these work processes involve interactions between workers, raw materials, equipment and the environment. These interactions can create hazards and risks to both health and accident risks if they are not carried out according to the correct procedures and steps. The purpose of this study is to determine the potential hazards and risk rating in order to provide recommendations for their control in the washing division of the "X" Company. The research method is observational, which is only observing objects without controlling any variables. The steps taken are to identify and analyze the existing hazards and the risks that may occur so that analysis of potential hazards, types of accidents that may occur and recommendations for their control is needed. The research results show that the potential hazards in the washing division are 52, consisting of 46 ergonomic hazards and 6 chemical hazards. On this basis, recommendations for control have been prepared to prevent accidents that must be carried out.

Logistics management is known as distribution and transportation management, while others call it physical distribution management. Distribution activities are very important for companies to deliver a product to consumers across various regions. The Regional Drinking Water Company (PDAM) Tirta Binangun Kulon Progo is one of the companies that produce Bottled Drinking Water (AMDK) under the product name AirKu. The high demand for AMDK AirKu products in 240 ml cup packaging was causing limited vehicles and the absence of a clear standard distribution route, which caused the distribution process to be carried out randomly. Therefore, to overcome the company's problems, it is possible to determine the Vehicle Routing Problem (VRP) route with the CVRP approach, where the route determination is based on fleet capacity. The method used was tabu search using the MATLAB application to minimize the bottled product delivery route traveled. The results obtained were the total distance traveled by 284.9 km. The proposed route had a distance savings of 118.26 km, which is better than the company route.
