Water accumulation in air conditioning (AC) drain pans can lead to corrosion and subsequent leaks, impacting AC system performance. This study focuses on implementing a monitoring system to track water levels and promptly discharge water to prevent corrosion. Using a research and development approach, the study evaluated the water level sensor's performance in measuring water levels and the pump's effectiveness in discharging water at specific levels, ensuring overall system reliability. The system utilized the NodeMCU ESP8266 microcontroller, a water level sensor, an LCD I2C 16x2 display, and Blynk as a smartphone-based monitoring platform. The findings demonstrated the effective functionality of the device in evacuating accumulated water from the AC evaporator. This was achieved through the activation of a water pump when the water level reached a threshold of 2 cm, thereby preventing potential leakage in the air conditioner's storage gutter.

When it comes to disease prevention and quality human development, the main focus is on promoting optimal under-five health and growth. Integrated service posts, also known as posyandu, often take center stage when it comes to tracking the development of under-fives in the community. However, there is still no effective system to measure the height and weight of toddlers in posyandu. Therefore, a spreadsheet-based tool was created that can help the process of measuring the height and weight of toddlers in posyandu to be easier, faster, and more accurate. The data can also help posyandu officers, medical personnel, and parents in making decisions related to the health and nutrition of toddlers. Height and weight monitoring is done through a spreadsheet. The components used in this tool are ESP 8266 as a microcontroller, ultrasonic sensor as a height meter, load cell sensor as a weight meter, LCD to display measurement notifications, rfid-rc522 to communicate data from rfid tags so that when scanning/tagging to rfid, the data from height and weight measurements will be uploaded to the spreadsheet. From the tests carried out, it is obtained that the device functions properly and helps posyandu officers to monitor and measure the growth of height and weight in toddlers efficiently.
在疾病预防和人类优质发展方面，主要重点是促进五岁以下儿童的最佳健康和成长。综合服务站（又称 "posyandu"）往往是跟踪社区五岁以下儿童发育情况的中心。然而，目前仍没有有效的系统来测量 posyandu 幼儿的身高和体重。因此，我们创建了一个电子表格工具，它可以帮助在儿童之家测量幼儿身高和体重的过程变得更简单、更快捷、更准确。这些数据还能帮助儿童之家官员、医务人员和家长做出与幼儿健康和营养有关的决策。身高和体重监测通过电子表格完成。该工具使用的组件包括作为微控制器的 ESP 8266、作为身高计的超声波传感器、作为体重计的称重传感器、用于显示测量通知的 LCD、用于从 RFID 标签传输数据的 RFID-RC522，以便在扫描/标记 RFID 时将身高和体重测量数据上传到电子表格。测试结果表明，该装置功能正常，可帮助儿童保护干事有效地监测和测量幼儿的身高和体重增长情况。

The electric motor plays an important role in an industry as a driver in a particular system, for example, rotating a pump impeller, fan or blower, moving a compressor, and lifting materials. The electric motor is sometimes called the "work horse" of industry. It is estimated that motors use about 70% of the total electrical energy in the industry. In making industrial motor monitoring and control systems using IoT with the blynk application, it works in showing the parameters of voltage, current, temperature, and RPM. The module consists of an electric motor, a DHT11 sensor, a PZEM004T sensor, an RPM sensor, and an ESP 8266 microcontroller. In the research conducted, the system made is capable of monitoring and controlling many modules. So that the overall monitoring and control system of electric motors in the company can be integrated into a system. In testing the voltage sensor with a measuring instrument there is an error value of 0.04%, while the current sensor has an error of 2.5%, followed by temperature testing there is an error of 1.8%. the RPM sensor parameter has a value of 1.17%. Remote manual control can be controlled using a smartphone with the blynk application so that the operator can immediately turn off the motor remotely if there is a problem or damage to the electric motor.

The largest water pollution occurs due to the disposal of waste from the industrial sector, while some of it comes from the household sector. In the labor-intensive industrial sector and the household sector, domestic liquid waste is generated. The high level of liquid waste pollution can be overcome by using a wastewater treatment plant (WWTP). Wastewater parameters according to research that has been done, namely pH, Turbidity, and Ammonia are very important parameters and the main priority for the quality of wastewater discharged into the environment. In this study, a prototype monitoring and controlling WWTP on the output channel was designed by measuring wastewater parameters and an Internet of Things (IoT) based pump output control system. This prototype is programmed with 2 mode options, namely auto mode where the controlling system works based on program commands with target limits, namely pH 6 – 9, Turbidity < 300 NTU, and Ammonia < 20 PPM, if the wastewater measurement value is on target, the system activates the outgoing pump. for direct disposal to the environment. Meanwhile, if it does not meet the target, the system activates the treatment pump to return the wastewater back to the WWTP. Then the manual mode, which is the controlling system, works by operating the operator directly to activate the outgoing or treatment pump on a smartphone using the Blynk application. In Auto and Manual mode, wastewater parameters can be monitored on a smartphone using the Blynk application. All sensors used have been calibrated with 2 calibrator solutions. The calibration results show an error value of 0.115 for the pH sensor, an error value of 0.075 for the Turbidity sensor, and an error value of 0.115 for the Ammonia sensor.

Data collection of goods entering and leaving the warehouse is very important. However, in large companies with hundreds of items being traded, manual recording can take a long time. To solve this problem, an RFID reader is used to record the name of the goods in the warehouse. By using RFID, the recording time can be reduced. Combined with the application of the Tsukamoto fuzzy algorithm, the system can predict the amount of inventory in the coming month to create sufficient inventory or not excess or less and the company can obtain optimal profits due to the process of buying and selling goods. This study aims to create an inventory system that can record goods through scans and can predict inventory in the coming month. The method used in this research is RFID technology and the Fuzzy Tsukamoto method. The results of this study indicate that the application can scan incoming or outgoing goods tags using RFID technology. The system can also predict the amount of inventory in the coming month using the Tsukamoto fuzzy method.

The use of fossil energy sources is increasing along with the increasing need to make reserves of fossil energy sources dwindling. Without the discovery of new reserves, oil in Indonesia will run out in the next nine years, natural gas will run out in 22 years, and coal will run out in 65 years. According to ESDM data, with current technology, the electricity potential from renewable energy reaches 432 GW, or 7-8 times the current total installed generating capacity. Wind energy (wind) is one of the renewable energy potentials, and the most widely available among all energy sources. Therefore, to anticipate the depletion of energy reserves that we have and to take advantage of the existing energy potential, research is being carried out on designing wind turbines so that we can take advantage of the existing energy potential, and not only depend on fossil energy which is depleting, and the main goal is know how to design and get the appropriate size and design of the turbine. From the design results obtained the value of the rotor diameter is 442 mm, the height of the rotor is 884 mm, the blade height is 439 mm, the diameter of the end plates is 486.2 mm, and the diameter of the shaft is 18 mm. As well as from the simulation, the maximum shaft stress value is 30,794 N/m2, the maximum displacement is 0.313 x10-4 mm, the minimum safety factor is 3.028, and the strain value is 0.114 x10-6, where these results can be used as a reference for the manufacture of this wind turbine later.

PT. Samihasa Kita is a glass product distributor company that was founded in 1989, which is located in the city of Semarang, Central Java, with sales area coverage in Central Java, D.I Yogyakarta, Jakarta, and Kalimantan. So far, PT Samihasa Kita has an erratic amount of demand for goods, as a result, sometimes the number of goods produced for sale with the goods purchased by consumers is not balanced. This resulted in PT Samihasa Kita not getting the maximum profit. Based on this problem, Fuzzy Tsukamoto logic was chosen to determine the optimal daily production amount. By using fuzzy logic can be determined the relative size of the production of goods. The Fuzzy Tsukamoto method can also be used to forecast sales in the coming month based on the amount of inventory. Thus the amount of production and demand for goods PT. Samihasa Kita is predictable and balances transactions. This research aims to be able to predict demand and procurement of goods that will have an impact on optimizing revenue at PT. Samihasa Kita.

Vannamei shrimp is a species of shrimp that has high economic value. In the process of trading vaname shrimp, there are different price classes. Determination of the price class of vaname shrimp is based on the size of the shrimp. But in the post-harvest process, the sorting of vaname shrimp is still done manually, namely by placing the white shrimp on a flat table and then separating it by size so that it takes a long time and the level of accuracy of the sorting process also becomes imprecise, as is done by cultivating in the coastal area of Madura, this is due to the limitations of available shrimp post-harvest processing equipment. In addition, the limited supply of electrical energy for the coastal area of Madura is also another factor that hinders the post-harvest process of vanname shrimp. The purpose of this study is to design and create a vannamei shrimp sorting system based on image processing. In processing this shrimp image using the Background Subtraction method. The Background Subtraction method is used as a separator between the object and the background. The sorting process is based on the size detection of shrimp by using the blob detection algorithm. BLOB (Binary Large Object) detection is an image segmentation method based on region growing. The goal is to analyze textures specifically and accurately. Because blob detection distinguishes colors that have thin gradations. Based on the tests that have been carried out, the average accuracy of the system in sorting vannamei shrimp is in the range of 90%.
