Conversion of CO2 to Formic Acid Using a Solid-State Electrolyte Device at Different Voltages

A potential environmentally beneficial method to reduce greenhouse gas emissions is the electrochemical conversion of CO2 to useful products like formic acid. However, a number of challenges must be addressed in order to synthesize formic acid at high concentrations. One of them is the generation of formate mixtures in conventional liquid reactors, which requires extensive purification processes to generate pure formic acid. A three-compartment reactor that introduces a solid-state electrolyte (SSE) between the anode and cathode has been developed to solve this issue. Numerous factors, such as the flow rates at which liquid and gas are utilized, have an impact on the reactor\u27s performance. In this investigation, pure CO2 gas was used with flow rates of 0.05 to 0.15 lpm entering the anode and 0.035–0.095 lpm of deionized water (DI) entering the cathode compartment at different voltages (2,98 V and 4,42 V). The results of this study demonstrate that a higher CO2 gas flow rate increased Faraday Efficiency (FE), as did the rise in DI flow rate. Furthermore, the inclination of HCOOH concentration was related to the increasing CO2 flowrate, but it declined along with the rise of DI flow rate. This trend was similar for the two voltages used in this experiment, but the reactor’s performance at 4,42 V was slightly better than its performance at 2,98 V. The highest formic acid concentration that could be produced in this experiment was 3.3% with a CO2 gas flow rate of 0.15 lpm and a DI water flow rate of 0.035 lpm

Tinjauan Yuridis tentang Penetapan Sebagai Saksi Pelaku yang Bekerja Sama (Justice Collaborator) pada Kasus Tindak Pidana Korupsi di Indonesia

The purpose of this study is to analyze the laws and regulations governing the legal position and role of justice collaborators, especially regarding the criteria for a person to be designated as a justice collaborator and what is the limit of legal reduction for a justice collaborator. This research is a normative juridical research that is descriptive and analytical, using a legislative approach related to the role and position of justice collaborators in corruption crimes. Data is obtained through document studies and analyzed using qualitative normative methods.Based on the results of the research, it is known that the determination of a person to be able to serve as a Justice Collaborator has not been expressly regulated in the Criminal Code or laws and regulations governing corruption crimes and there are no rules governing the amount of sentence reduction that can be received by a justice collaborator. The suggestion of this research is the need for a special regulation on justice collaborators which regulates the determination as a cooperating whistleblower (justice collaborator), especially about the definition of “Main Perpetrator” and the need for a clear determination of the amount of sentence reduction that can be given to a justice collaborator as a guideline for law enforcers in determining a person as a justice collaborator in a corruption case

Analisis Potensi Pembangkit Listrik Tenaga Surya (PLTS) di Gedung Kantor Bupati Kabupaten Temanggung

The government has targeted a 23% increase in the use of renewable energy by 2025. The Ministry of Energy and Mineral Resources (ESDM) in Indonesia has taken steps to achieve this goal by issuing Circular Letter No. 363/22/MEM.L/2019, urging the installation of rooftop solar power systems (PLTS) on buildings. In response to this directive, the office of the regent of Temanggung Regency has been designated for the installation of rooftop PLTS.

Uji Performansi Mesin Pengisi Bumbu Pasta Semi Otomatis untuk Bubur Pedas Instan

The main problem faced by the instant bubur pedas business unit is the filling of pasta seasoning in the packaging. The packaging of seasoning paste is currently done manually by putting the seasoning paste into the plastic packaging using a spoon. The weakness of the manual filling technique was that it has a small filling capacity and needs to be more practical and hygienic. Through this research, an effort was made to overcome these problems by creating a semi-automatic pasta seasoning filling system. This research aims to conduct performance tests on a semi-automatic pasta seasoning filling machine for instant bubur pedas and analyze the relationship between the rotation of the stepper motor and the mass of pasta seasoning coming out of the filling machine. The performance test carried out on the machine is in the form of an analysis of packaging time and packaging capacity. The independent variable was the number of stepper motor revolutions, ranging from 1 to 20. Based on the performance test results, the highest packaging capacity was obtained at 208 packs/hour in the treatment of stepper motor rotation one time, with the number of spices released at 3.29 grams. Increasing the mass of packaged spices requires more stepper motor revolutions, increasing the time needed for each packaging cycle. The stepper motor rotation and the mass of seasoning paste coming out of the filling machine show a consistent linear relationship with a coefficient of determination (R2) value of 0.9983. These results show that this machine can maintain the consistency of the mass of seasoning released per stepper motor rotation.

Modified Rainwater Harvesting Design to Prevent the Breeding of Aedes aegypti Mosquitoes

Clean water is a basic need for every human being, aligning with the sixth goal of Sustainable Development, which ensures that all communities have access to clean water. Early Childhood Education (PAUD) Pelita Hati in Sumber, Kramat, Kranggan, Temanggung Regency, needs 920 liters of clean water per day. Still, during the dry season, the need for clean water is not met. One solution is to utilize a rainwater harvesting (RWH) system, but it leads to mosquito breeding, especially Aedes aegypti. A simple prototype modified RWH by integrating it with the Prevent Aedes Pump (PAP) technology with an internal aquarium filter pump was designed to prevent mosquito breeding. The observation was conducted for 10 days, and the results showed that installing the internal filter pump reduced the number of Aedes aegypti larvae from 4 to 0. The system also reduced the levels of dissolved iron from 0.2 mg/L to 0.02 mg/L and coliform bacteria from 560 MPN/100 ml to 15 MPN/100 ml
