Abstract

Tofu industrial wastewater is a contributor to environmental pollution. Wastewater contains high levels of COD and TSS. The purpose of this study was to determine the effectiveness of reducing pollutant loads in tofu liquid waste by using the phytoremediation method using water jasmine (Echinodorus Palaefolius). The initial stage of the research was a preliminary test to determine the initial content of the waste. The acclimatization process is carried out by observing the process of plant growth during the research process. To maximize plant growth, dilution is carried out with various concentrations of 25% wastewater with 75% diluting water and 50% wastewater with 50% diluting water. Sampling was carried out every 12 hours for 5 days. The results showed that the highest effectiveness of COD reduction occurred in RFT 25% with a residence time of 12 hours at 39.83%, while for TSS parameters the highest effectiveness was at RFT 25% with a residence time of 12 hours by 69%.

Abstract

Adolescence is a critical developmental stage in which individuals often experience psychological challenges such as overthinking, stress, and emotional dysregulation. Limited self-awareness and low mental health literacy exacerbate these challenges, contributing to poor decision-making, heightened anxiety, and stigma. Innovative approaches are needed to promote adolescent mental health.This study aimed to examine the effectiveness of the “Outbond from Overthinking to Understanding” program in improving self-awareness and mental health literacy among adolescents.A quasi-experimental design with pre-test and post-test control groups was conducted among 120 students (60 intervention, 60 control) from senior high schools (SMA) and vocational high schools (SMK) in Kediri, Indonesia. Participants were selected using cluster sampling. The intervention group participated in a one-day outbound program consisting of six activity stations, while the control group received a leaflet on adolescent mental health. Self-awareness was measured using the Self-Reflection and Insight Scale (SRIS), and mental health literacy was assessed with the Mental Health Literacy Scale (MHLS). Data were analyzed using paired and independent t-tests.The intervention group showed significant improvements in self-awareness (Mean Difference = +13.4, p < 0.001) and mental health literacy (Mean Difference = +17.7, p < 0.001), while the control group demonstrated no significant changes. Post-test comparisons revealed higher mean scores in the intervention group compared to the control group for both self-awareness (78.6 ± 7.9 vs. 66.3 ± 8.6, p < 0.001) and mental health literacy (80.2 ± 8.1 vs. 65.0 ± 8.7, p < 0.001).The “Outbond from Overthinking to Understanding” program significantly enhanced self-awareness and mental health literacy among adolescents. Outbound-based experiential learning offers a promising, engaging, and practical strategy for promoting adolescent mental health and should be considered as a complementary approach to conventional school-based education.

Abstract

One of the main challenges faced by small-scale ruminant farmers is the high cost of feed and the low efficiency of forage utilization, both of which directly increase production costs and reduce profit margins. This community service program aimed to improve goat feed efficiency through the application of appropriate technology in the form of a grass chopping machine, combined with feed management strengthening. The program was implemented with a partner goat farmer in Sumber Karya Village, Binjai Timur District, using a participatory approach that included a needs assessment, the design and fabrication of a 100 kg/hour grass-chopping machine, operational and maintenance training, and feed management assistance. The results indicate that the application of the chopping machine reduced forage waste from approximately 40% to less than 10%, resulting in monthly feed cost savings of up to ±30%. Improved feed efficiency also contributed to faster weight gain and a shorter fattening period. These findings demonstrate that integrating appropriate technology with management support effectively enhances feed efficiency and improves the economic sustainability of smallholder goat farming.

Abstract

Reproductive health issues remain a significant concern among adolescents. Data from the Indonesian Demographic and Health Survey (IDHS) in 2012 indicate an increase in premarital sexual behavior among adolescents, which may lead to various negative consequences such as unwanted pregnancy, abortion, sexually transmitted infections, and sexual violence. This condition highlights the importance of health education efforts to improve adolescents’ knowledge of reproductive health. This study aimed to determine the effect of health education counseling on adolescents’ knowledge of reproductive health. This study employed a quasi-experimental design using a one group pre-test and post-test approach. A total of 20 respondents were selected using purposive sampling. Data were collected using a reproductive health knowledge questionnaire. Health education counseling was provided after the pre-test, followed by a post-test to assess changes in knowledge levels. Data analysis was conducted using the paired sample t-test. The results showed an increase in adolescents’ knowledge levels after receiving health education counseling. Statistical analysis revealed a significant difference between knowledge levels before and after the intervention (p = 0.036). Conclusion Health education counseling has a significant effect on improving adolescents’ knowledge of reproductive health

Abstract

This research is motivated by some students who have not been able to concentrate in learning, so that efforts are needed to improve student learning concentration by using the right techniques. The purpose of this study was to determine the effectiveness of efforts to improve student learning concentration using Self-management techniques through group guidance in class XI IPA 1 SMA Tamansiswa Teluk Betung in the 2022/2023 academic year". This research uses the Guidance and Counseling Action Research (PTBK) method which is carried out in two cycles. Based on the results of the study, it is known that the problem of learning concentration in students before obtaining group guidance services with Self-management techniques obtained 50.25% after getting group guidance services with Self-management techniques in cycle I reached 56.25% in the low to medium category. Thus it can be concluded that the Self-management technique is effective in increasing learning concentration, this is indicated by the acquisition of cycle II results implemented by researchers.

Abstract

Accurate and real-time people counting is essential for crowd management and public safety, yet achieving precision in high-density environments remains a challenge due to severe visual occlusion. While the recently released YOLO11 architecture introduces advanced features such as C3k2 and C2PSA modules, its performance as a pre-trained model for people counting tasks has not been fully explored. This study evaluates the efficacy of a head-detection-based fine-tuning strategy using the YOLO11 model, compared against the default pre-trained baseline. The fine-tuning performance is analyzed across three distinct scenarios: S1 (full fine-tuning at 960 pixels), S2 (partial backbone freezing at 960 pixels), and S3 (partial freezing at 640 pixels). The fine-tuning process was conducted using the CC_Mach_1 dataset from Roboflow Universe, which consists of high-density images annotated for head detection. The results demonstrate that the baseline pre-trained YOLO11, which relies on full-body features, exhibits extremely limited performance with an mAP@0.5 of 0.017 and a Mean Absolute Error (MAE) of 100.3. In contrast, the fine-tuned scenarios achieved substantial improvements, led by S1 which reached the highest accuracy with an mAP@0.5 of 0.682 and reduced the MAE by 62% to 37.8. While S2 remained highly competitive with an MAE of 39.6, the performance in S3 declined to 46.9, confirming that lower input resolutions limit the model's ability to identify small-scale head features. These findings provide empirical evidence that domain-specific fine-tuning for head detection substantially improves the robustness of YOLO11 against occlusion. Beyond technical accuracy, this detection-based approach offers a more computationally efficient alternative to traditional density-map-based methods, making it highly suitable for deployment in real-time surveillance systems for large-scale public monitoring.
