Pendampingan Pasien Tuberkulosis melalui Penerapan Aplikasi Zero TB Berbasis Patnership Community System: Supporting Tuberculosis Patients through the Application of Zero TB Application Based on Patnership Community System in Surabaya
Indonesia is ranked third with the most significant number of pulmonary TB (Tuberculosis) patients in the world, after China and India. In 2017, there were 420,994 new TB cases in Indonesia. The survey showed that 68.5% of male participants smoked, while only 3.7% of female participants smoked. This service activity aims to assist TB patients through the Zero TB application based on a community partnership system for TB prevention and treatment. The training effectively improved participants' knowledge, behavior, and compliance. There was a significant change in the level of expertise, where the pre-test results showed that 50% of respondents had low knowledge, but after counseling using the Zero TB application, 83.4% had high knowledge. Behavioral changes also improved, with 53.3% of respondents showing good changes in the pre-test, which increased to 100% after the intervention. The level of treatment adherence also increased from 93.3% of respondents with low adherence in the pre-test to 96.6% with high adherence in the post-test. It is hoped that participants' increased knowledge, behavior, and adherence can prevent TB while raising public awareness of the importance of TB treatment, especially at Yayasan Bhanu Yasa Sejahtera (YABHYSA)
Pemberdayaan Komunitas Gay dan Waria Melalui Health Promotion Model dan Budidaya Tanaman Hidroponik: Empowering Gay and Transgender Communities Through Health Promotion Models and Hydroponic Plant Cultivation
Currently, the number of global HIV cases has reached 37.7 million people, and around 680,000 to 1 million people die every year due to HIV/AIDS. Meanwhile, in Indonesia, currently, HIV cases continue to increase from year to year; new findings are estimated to reach 7,650 people, compared to 7,036 people in the previous year. The high number of HIV cases in Indonesia is caused by several methods of massive transmission that are less controlled, including through heterosexuals (51.5%). This study aims to empower gay and Transgender Communities Through Health Promotion Models and Hydroponic Plant Cultivation—methods for implementing activities, in the form of lectures, discussions, and practice. The training, which was held for 2 days, effectively increased participants' knowledge and changed attitudes. Evidenced by significant changes in knowledge levels, the results of the pretest knowledge were high at 26.5%, then after the post-test, knowledge increased to 91.2%. Meanwhile, the pretest results for respondents' good attitude were 15%, and after the post-test, good attitude increased significantly to 100%. Thus, it is hoped that with the knowledge and changes in attitudes of the participants, it can prevent and reduce the number of HIV cases in the gay and transgender community in the Pacar Kembang sub-district, Surabaya

Comparison of Characteristics and Antibacterial Activity of Mandai Cempedak Vinegar with Variations in Fermentation Methods
Mandai, a traditional fermented food product from East Kalimantan, is derived from the edible mesocarp of the cempedak (Artocarpus champeden) fruit. This ancestral fermentation technique, passed down through generations, is known to produce lactic acid bacteria (LAB) with potential probiotic properties. This study aimed to characterize LAB isolated from mandai vinegar and evaluate their antibacterial activity under two distinct fermentation conditions: a defined starter culture of Lactobacillus casei strain Shirota and spontaneous fermentation in a 10% NaCl solution. The latter, referred to as salt fermentation, yielded three bacterial colonies, while the starter culture method produced four. All isolates from both methods shared similar morphological characteristics, including a rod shape, white coloration, entire margins, and convex surfaces. Further analysis confirmed they were Gram-positive, catalase-negative, and indole-negative, with the ability to ferment various carbohydrates. While all LAB isolates demonstrated generally low antibacterial activity against Escherichia coli ATCC 25922, isolate CML 1 exhibited the highest antibacterial potential. These findings highlight the potential of mandai vinegar as a source of functional LAB, warranting further investigation into its applications as a functional food ingredient
Coconut Shell Charcoal Adsorbent with Variations in Activation to Reduce BOD (Biochemical Oxygen Demand) and TSS (Total Suspended Solid) Levels in Liquid Tofu Waste: Adsorben Arang Tempurung Kelapa dengan Variasi Aktivasi dalam Menurunkan Kadar BOD (Biochemical Oxygen Demand) dan TSS (Total Suspended Solid) pada Limbah Cair Tahu
Wastewater from tofu production conntains high concentrations of organic matter, particularly Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS). Without proper treatment, this waste has the potential to pollute surrounding water bodies and harm aquatic ecosystems. This research explores the use of coconut shell charcoal as a natural adsorbent to reduce BOD and TSS levels in tofu wastewater. The charcoal was physically activated by heating it at 105°C for three different durations: 15, 60, and 180 minutes. This treatment aimed to improve its surface area and porosity, enhancing its adsorption capacity. Laboratory analysis showed a significant decrease in both BOD and TSS, with the highest efficiency observed at 180 minutes of activation. These findings suggest that coconut shell charcal, a widely available and underutilized material, can serve as an effective and environmentally friendly option for simple wastewater treatment at a local level
