A freezer box temperature monitoring system using solar panels as alternative power is an important technology to ensure the quality of stored products. This research develops a WiFi-based temperature monitoring system that uses a DS18B20 temperature sensor, a PZEM-004T digital sensor, and an ESP8266 module to read and send real-time data to a website platform. Data is collected through a temperature sensor connected to the ESP8266 microcontroller, then displayed on the LCD screen and uploaded to the server for further monitoring via WiFi connection. The results show that this system successfully maintains the freezer box temperature at optimal conditions with an average temperature value of -24.82°C and a temperature range ranging from -28.81°C to -19.63°C. The voltage values are in the range of 197.10 V - 218.70 V, current between 0.02 A - 1.03 A, and power between 158 W - 186.80 W.

Puskesmas Manduro is one of the public health service centers located at Jl. Raya Ngoro KM 14, Manduro MG Village, Ngoro District, Mojokerto Regency, East Java. As a basic health service center, it is important to monitor air quality and maintain air quality in accordance with the Environmental Quality Standard (SBMKL). This study aims to design an Internet of Things-based air quality detection system that utilizes Sansevieria plants as one of the natural solutions in absorbing air pollution levels. The method used is the research and development method which includes system design, tool making, website design, tool integration, and system testing. The sensors used are MQ-7 sensors for carbon monoxide gas, MQ-135 sensors for nitrogen dioxide gas, MQ-131 sensors for ozone gas, Dust GP2Y1010AU0F sensors for PM2.5, and DHT22 sensors for temperature and humidity. The results of testing the system for three days obtained the average temperature 30.64C, humidity 73.62%, CO 735.63 µg/m³. NO2 27.30 µg/m³, O3 32.13 30 µg/m³, and PM2.5 2.14 µg/m³. Based on the test results that have been carried out, it shows that the air quality monitoring system can provide data, graphs, and indicator levels for the Air Pollution Standard Index (ISPU). Air quality data obtained from sensors can be displayed on the LCD and also displayed in real-time through the website.

Currently, air conditions on earth are getting worse over time due to the impact of air pollution. One example of air pollution is motor vehicle exhaust emissions. Exhaust gas emissions are the result of combustion residue in motor vehicle engines that use fuel. Motor vehicle exhaust emissions contain carbon monoxide (CO), hydrocarbons (HC), carbon dioxide gas (CO2) which have a negative impact on the environment and living creatures. This research will create a motor vehicle exhaust emission detection device. In this design, an Arduino microcontroller was used and the manufacture of this tool used an MQ-7 gas sensor to detect carbon monoxide (CO) gas, an MQ-2 sensor to detect hydrocarbon gas (HC), and an MQ-135 to detect carbon dioxide (CO2) gas. The emission test results will be sent to the application, this data includes plate number, vehicle type, vehicle brand, vehicle year and emission test results. The results of the carbon monoxide (CO) gas sensor calibration test taken from 5 data showed an error of 5.51%. The results of the hydrocarbon (HC) gas sensor calibration test taken from 5 data showed an error of 4.23%. The results of the carbon dioxide (CO2) gas sensor calibration test taken from 5 data showed an error of 1.06%. In the implementation of the tool and application, the test results were obtained for 15 vehicles. Where the highest hydrocarbon (HC) gas content value was 412 ppm, the highest carbon monoxide (CO) gas content value was 1.48%, and the highest carbon dioxide (CO2) gas content value was 21.4%.

Study area this research was conducted on November 12th â€“ 21st, 2021, located in Kota Pinang, South Labuhanbatu, North Sumatra, Indonesia. The results of this study can provide a report on the results of the analytical test carried out in the laboratory of the University of Brawijaya. South Labuhanbatu Regency is geographically located at 1Â°26'00'' - 2015'55'' North Latitude. 99Â°40'00'' - 100Â°26'00'' East Longitude. Generally, South Labuhanbatu Regency is located at an altitude below 100 meters above sea level. The type of research is exploratory research. The result and discussion gave the best replacement of water content in honey at Apis dorsata as an average of 27%. It showed that the higher the water content and acidity of the honey will explain the lower the quality of the honey. The best replacement levels of sucrose in honey at Heterotrigona itama as an average of 68.5%. The percentage level of sucrose showed that honey with a moisture content of more than 17%, with a total sugar content of <83% is susceptible to cosmetological yeast fermentation. The best pH of Honey placed at Apis dorsata is an average of 2.350 (Acid). The data showed that the low pH value and high acidity can increase the shelf life of honey because it does not support the growth of microbes.

Micro, Small, and Medium Enterprises (MSMEs), especially in the snack industry sector, such as cassava crackers, play an important role in supporting the Indonesian economy through job creation and contribution to Gross Domestic Product (GDP). However, MSMEs often face challenges in maintaining and expanding their market share amid increasingly fierce competition. This study aims to analyse the role of social capital in strengthening market segmentation strategies at Sadariyah Cassava Crackers Business in Blitar Regency. The method used is descriptive qualitative, with data collection techniques through in-depth interviews, direct observation, and documentation. The informants in this study were five people, consisting of business owners, employees, regular customers, and local community leaders. The results show that social capital, which includes strong social networks, trust between businesses and consumers, and the application of local social norms such as gotong royong, contributes significantly to expanding the market and maintaining customer loyalty. The market segmentation strategy applied based on demographic, psychographic, and consumer behaviour factors proved effective in reaching various customer groups. These findings imply that the synergy between social capital and the right market segmentation strategy can improve the competitiveness of MSMEs in a competitive market and promote sustainable business growth.

Penelitian ini mengkaji evolusi dan klasterisasi tema dalam pengelolaan limbah berkelanjutan menggunakan teknik analisis jaringan VOSviewer. Melalui visualisasi data bibliometrik, kami mengidentifikasi fokus utama dalam literatur terkait pengelolaan limbah, yang mencakup teknologi daur ulang, integrasi keberlanjutan dalam kebijakan pengelolaan limbah, serta dampak pandemi global terhadap praktik pengelolaan limbah. Analisis menunjukkan bahwa ada transisi dari pendekatan yang berfokus pada teknologi ke strategi yang lebih holistik yang mendukung tujuan pembangunan berkelanjutan. Kami juga mengeksplorasi kolaborasi antar penulis dan mengidentifikasi area riset potensial yang belum banyak dieksplorasi, seperti penggunaan plastik biodegradable dan penilaian siklus hidup yang lebih efisien. Studi ini menawarkan wawasan yang berharga bagi pembuat kebijakan dan peneliti untuk meningkatkan strategi pengelolaan limbah dan mendorong inisiatif yang lebih berkelanjutan.

Purpose: The Community Engagement Program (PKM) aims to address the challenges faced by TPST 3R Mulyoagung Bersatu in managing financial data related to waste management. Enhance their capacity in Environmental Management Accounting through targeted mentoring and accountability. Method: Activities were conducted under an existing MoU between Politeknik Negeri Malang and TPST 3R Mulyoagung Bersatu. A participatory, hands-on approach was used, involving field observations, informal discussions, and interactive training sessions tailored to the partner’s specific needs.. Practical Applications: Participants gained practical knowledge in applying environmental accounting principles in their daily operations. The training improved their ability to systematically record and manage financial data, directly contributing to more transparent and efficient 3R waste management practices. Conclusion: The program successfully strengthened the understanding and implementation of environmental accounting among TPST managers. It exemplifies productive collaboration academia and the community, where mutual learning leads to sustainable and impactful solutions for environmental challenges.
