Abstract

IoT devices can range from smart home devices such as thermostats and security systems to industrial control systems used in manufacturing and other industries. One focus of the IoT-based monitoring and control concept is monitoring and controlling water heaters based on IoT technology to support the creation of a smart home. The purpose of this research is to create a system that can control and monitor water heaters remotely using the Android Studio application so that the water temperature in the heater can be ensured for safety, comfort, reliability, and energy efficiency. The system is designed using temperature sensors and water flow sensors, and then the data is processed with the NodeMCU microcontroller and then sent to the Firebase website to be displayed on the application. The application built can set a large amount of water and heat it to the desired temperature before sending it to Firebase and then to NodeMCU. The result of this research is an application that is able to control and monitor a water heater with an average measurement difference of 0.38 liters and an average error percentage of 7.11% The relay control system in the application has an average delay time of 3.6 seconds.

Abstract

Batik coloring still uses synthetic dyes, so the disposal of coloring waste should not be careless. Most batik craftsmen process their batik waste by settling the waste liquid for a long time. The process is very ineffective. The purpose of this research is to design a batik processing tool that is cheap and effective. The research method uses the electrocoagulation method. The electrocoagulation method is an electrochemical water treatment. The design of this batik waste treatment tool consists of five parts including: (1) Electrocoagulation Tub, (2) Skimmer, (3) Electrode, (4) Sand Filter, and (5) Studge Drying Bed. This tool works with 900 watts of power with an output of 20-40 volts DC. The capacity of liquid waste is 50 liters. Duration of waste treatment for 2 hours. The electrocoagulation method is able to reduce the values of BOD5, COD, TSS, and TDS in batik dye waste. The pH of wastewater which is still high can be reduced by giving alum.

Abstract

Cilacap Regency is a coastal area south of the island of Java. The purpose of this study is to determine the potential of raw materials available in the South Cilacap Coastal area and to determine the potential power that can be generated for the PLTH system through the calculation of the raw material data that has been obtained. This research method begins with direct measurements of wind speed and light intensity. Both devices read data in real time and connect online. The data obtained is processed to determine the wind speed and the average intensity of sunlight. The results of these calculations are entered into the equations to calculate the potential power that can be generated. Based on the calculation, the average wind speed is 3-4 m/s and the light intensity is 54612 watt/m2. The results of the calculation of the potential power that can be generated from the PLTB system in the coastal area of ??South Cilacap is equivalent to 508 watts/day. The potential power that can be generated from PLTS is 10.8 kW/day. The total potential power that can be generated from the PLTH system on the coast of South Cilacap is equivalent to 273.22 kWh/day.

Abstract

Indonesia has the potential of sea wave energy with the second largest coastline having a density of up to 20 kW / m2. Currently, the use of sea wave technology is still at the prototype stage, with several weaknesses such as erratic sea waves, tides and ocean currents so that they can affect the power generated in ocean wave energy. The results of ocean wave energy in mechanical arrays cannot be utilized because of erratic waves. The higher the wave, the greater the power generated and vice versa. If this problem is not resolved, it can cause unstable power output and cause damage to electronic equipment. The solution to this problem is to modify the DC-DC buck boost converter circuit using the Hyeteresis band method, which limits voltage surges below or above to produce the desired voltage in order to maintain constant power and as energy for storage in the storage system. The result of this study is that the performance of DC generators in producing voltage is greatly influenced by speed. At low speeds, the voltage produced by the generator is still too low to charge the battery or in other words cannot be in a perfect charging position, while at maximum speed it produces voltage with Achieve a level sufficient for battery charging. Therefore, control and adjustment of generator speed is key in maximizing battery charging efficiency using a buck-boost converter.

Abstract

Ujungmanik Village, Kawunganten District, Cilacap Regency, which is in the Segara Anakan Cilacap area, has natural resources, especially eucalyptus plants, which have the potential to develop the economy of the village community. The biggest problem faced by LMDH Dadi Makmur as a unit that manages the eucalyptus oil business is that after the production of eucalyptus oil distillation, it will produce residual waste from cajuput oil twigs and leaves with quite a large volume and only be left piled up around the yard where the distillery is, causing area storage of essential oil raw materials is narrow and also takes a long time to become organic fertilizer. The innovation offered through this community service activity is implementing a briquette printing machine from eucalyptus oil refining waste which is energy efficient and based on solar panels. The results of the dedication show that the eucalyptus oil waste processing activity in addition to reducing environmental pollution also produces biomass briquettes that can be utilized by the residents of Ujungmanik Village as a leading economic product of Ujungmanik Village.  Keyword: Cajuput oil, briquette, solar panels

Abstract

Limbah cair dari industri batik, terutama yang mengandung bahan kimia berbahaya seperti pewarna sintetik dan logam berat, menjadi masalah lingkungan yang signifikan di berbagai wilayah industri batik, termasuk Cilacap. Penelitian ini mengeksplorasi penerapan teknologi elektrokoagulasi sebagai metode pengolahan limbah batik, dengan fokus pada optimasi proses dan integrasi sistem filtrasi-adsorpsi. Proses elektrokoagulasi terbukti efektif dalam menurunkan parameter kualitas air, seperti BOD, COD, TSS, dan konsentrasi logam berat, seperti kromium, yang pada akhirnya memenuhi standar baku mutu yang ditetapkan oleh regulasi lingkungan (PERDA No. 5 Tahun 2012 Provinsi Jawa Tengah). Hasil penelitian menunjukkan penurunan signifikan pada BOD, COD, TSS, dan kromium, dengan penerapan sistem filtrasi-adsorpsi lebih lanjut meningkatkan efektivitas pengolahan. Penelitian ini memberikan kontribusi ilmiah yang signifikan dalam menawarkan solusi pengolahan limbah yang ramah lingkungan dan berkelanjutan untuk industri batik, dengan potensi adopsi yang lebih luas di tingkat global. Teknologi ini tidak hanya mengurangi dampak negatif limbah terhadap lingkungan tetapi juga memungkinkan limbah batik untuk diproses kembali menjadi produk berguna, seperti malam (candle wax). Temuan ini menunjukkan potensi penerapan teknologi elektrokoagulasi dan filtrasi-adsorpsi sebagai solusi inovatif untuk pengelolaan limbah industri batik secara global.

Abstract

Electrical energy is one of the most important energies in everyday life so high-voltage electrical equipment has a vital role in maintaining the reliability of electric power distribution. The corona effect is caused by insulation failure in high-rise equipment which results in disrupted electrical power distribution. The purpose of this research activity is to produce a multi-sensor tool to test the condition of equipment in distribution network booths that have experienced the corona phenomenon. The input data from several sensors used, such as the ozone sensor, will detect ozone gas exposed in the 20kv chamber, detection of ultraviolet light by the UV sensor module, and detection of sound frequency from the hissing of equipment through the microphone sensor experiencing corona will be processed by the Microcontroller and if the value is detected exceeds the reference value that has been set, the output in the form of an LCD will display a corona symptom warning message and instruct the buzzer alarm to sound. The results showed that the prototype of the corona detector was able to identify ozone levels with a maximum value of 21.88 ppb, the largest UV index value of 336, and a maximum hissing frequency of 157 dB in distribution cubicles that experienced the corona effect.
