Nile tilapia (Oreochromis niloticus) culture requires an efficient and low-cost feeding strategy that can support fry growth and survival. This study aimed to analyze the effects of three types of natural feed, namely silk worms, earthworms, and snails, on absolute length growth, absolute weight growth, and survival of Nile tilapia fry. The study was conducted at the Aquaculture Laboratory, Faculty of Science and Computer Science, Universitas Muhammadiyah Gorontalo, from January 31 to March 2, 2026. An experimental method was applied using a Completely Randomized Design consisting of three treatments and three replications. A total of 45 Nile tilapia fry were reared in 9 plastic containers filled with 10 L of water, with 5 fish in each container. Growth and survival data were analyzed using ANOVA at the 5% significance level, while water quality was analyzed descriptively. The results showed that the type of natural feed had no significant effect on absolute length growth, absolute weight growth, and survival. Descriptively, silk worms produced the highest length and weight growth, with values of 2.99 cm and 6.37 g, respectively. Snails produced the highest survival rate of 86.66%. Water quality remained stable, with temperature ranging from 26.3 to 26.8°C, pH from 7.6 to 7.9, and dissolved oxygen from 5.2 to 5.6 mg/L. These findings indicate that silk worms are potential natural feed for improving growth, while snails support the survival of Nile tilapia fry.

Kebonagung hamlet in Sukolelo village is an area where the majority of residents cultivate bananas. The abundant banana production generates a considerable amount of waste, one of which is banana stems that are usually piled up, burned, or left to rot without further use. Therefore, this community service project aims to provide a comprehensive overview of the potential use of banana waste as raw material for organic compost in Kebonagung Hamlet, Sukolelo Village. The methods used in this study involved banana farmers as research subjects and banana stems as research objects, with data collection techniques including field observations, interviews with farmers, and composting experiments. Simple laboratory analysis shows that compost from banana waste contains 1.8% nitrogen (N), 0.9% phosphorus (P), and 2.3% potassium (K), making it highly potential for use as compost material. In addition, composting activities can create new jobs through the development of organic fertilizer management business units at the village level. This is in line with Sustainable Development Goal (SDG) 12 on responsible consumption and production. According to Santoso (2020), the benefits of compost include: (a) improving soil structure, (b) increasing soil water storage capacity, (c) increasing soil microbial activity, and (d) reducing dependence on chemical fertilizers. Qualitative data were analyzed through data reduction, data presentation, and conclusion drawing in the form of nutrient content analyzed using simple laboratory tests to determine the levels of N, P, and K. The banana waste composting process went well. In the first week, the temperature of the compost pile increased to 45°C, indicating high microorganism activity. The temperature stabilized at around 50–55°C. After the second week, the temperature decreased and stabilized close to the ambient temperature, indicating that the compost was mature.

Marketing is the backbone of a business’s existence. Various ideas, creativity, and innovations in marketing continue to evolve in different forms. To attract a large number of consumers, some businesses engage in overclaim marketing. While this strategy may bring positive outcomes for some companies, it can also have negative consequences for others. One brand that has practiced overclaim marketing is Daviena Skincare. This study aims to analyze the impact of overclaim marketing on consumer trust in Daviena Skincare products. The research was conducted using a qualitative descriptive approach, with data obtained through digital tracing and observation. The findings indicate that overclaim marketing in the skincare industry, as practiced by Daviena Skincare, has negatively affected consumer trust. The overclaims identified include promises of instant results, false claims about premium ingredients, and unverified testimonials. An investigation by Doctor Detective revealed significant discrepancies between marketing claims and the actual product composition, such as Niacinamide, which was advertised at 10% but was not detected in laboratory tests. These findings contradict the marketed product benefits, leading to consumer disappointment and decreased brand loyalty. This phenomenon underscores the urgency for brands to be more transparent and ethical in their marketing strategies. Therefore, overclaim marketing practices must be eliminated to maintain the integrity of the industry and protect consumers’ rights to accurate information and products that align with their claims.

Bridge infrastructure is a vital component of transportation systems that is vulnerable to structural damage caused by dynamic loads, environmental factors, and aging. Early crack detection is crucial to prevent structural failures that may lead to catastrophic consequences. This study aims to develop a non-destructive detection method based on acoustic sensors to identify cracks in bridge structures with higher sensitivity and accuracy compared to conventional visual inspections. The research was conducted through laboratory experiments and field tests using acoustic sensors, data acquisition devices, and signal analysis software. The procedure included sensor installation on a bridge model, simulation of artificial cracks with varying sizes and positions, recording of acoustic wave signals, and data analysis using frequency spectrum, amplitude, and waveform pattern approaches. The results show significant differences between normal and cracked conditions in the frequency spectrum, where cracks produced amplitude anomalies at specific frequencies. Amplitude analysis revealed a positive correlation between crack size and acoustic signal intensity, while waveform pattern analysis demonstrated the influence of crack position on distortion levels. Cracks located at the center generated the highest distortion, followed by joints and edges. These findings confirm that acoustic sensors, particularly fiber-optic-based ones, offer advantages such as high sensitivity, reliability under complex environmental conditions, and the ability to detect subsurface cracks. The implications of this research highlight the potential development of an acoustic sensor-based structural health monitoring system integrated with real-time analysis software, thereby supporting preventive maintenance, extending infrastructure lifespan, and enhancing transportation safety.

Modern agriculture faces serious challenges such as climate change, soil degradation, and dependence on chemical fertilizers and pesticides, which negatively impact the environment and human health. To support sustainable food security, innovative and environmentally friendly solutions are required. One promising alternative is the use of endophytic bacteria as biological agents to enhance plant growth without relying on synthetic chemicals. This study aims to examine the role of endophytic bacteria in organic farming systems through a combination of laboratory tests and field experiments. The research stages include isolation and identification of endophytic bacteria from plant tissues, testing the ability of the bacteria to support plant growth in vitro, and applying it to organic farmland to evaluate resistance to pests and crop yields. The independent variable in the study is the type of endophytic bacteria, while the dependent variables include plant growth rates, pest resistance, and crop productivity. Data analysis was performed using descriptive statistics and ANOVA, followed by post-hoc tests to determine the effectiveness of the treatments. The results showed that treatments with endophytic bacteria, both singular and combined, significantly improved vegetative growth, reduced pest attacks, and increased crop yields compared to the control. The combination of bacterial isolates proved to have a stronger synergistic effect than single treatments. These findings demonstrate the potential of endophytic bacteria as natural biofertilizers and biopesticides to support environmentally friendly organic farming.

Drug-resistant tuberculosis (TB) is an escalating global health issue, particularly with the rise of multidrug-resistant (MDR-TB) and extensively drug-resistant TB (XDR-TB), which complicate treatment and control efforts. Resistance to both first-line and second-line drugs weakens the effectiveness of standard WHO-recommended therapies, while alternative drugs can cause severe side effects and reduce patient adherence. This study aims to explore the integration of bioinformatics and pharmacogenomics in supporting personalized TB treatment to improve therapeutic success and reduce the risk of further resistance. The research employed a laboratory-based experimental design with a bioinformatics approach, involving TB patients with clinical evidence of drug resistance. Clinical samples were analyzed through whole genome sequencing to identify gene mutations associated with resistance, followed by pharmacogenomic mapping to predict pharmacological responses based on patients’ genetic variations. The results revealed several specific gene mutations consistently linked to resistance and produced individualized therapeutic recommendations that were more targeted than standard protocols. Effectiveness evaluation demonstrated that genome-based personalized therapy yielded higher treatment success rates, faster recovery times, and lower rates of subsequent resistance. These findings highlight the significant potential of precision medicine in TB management, particularly for resistant cases that are difficult to treat with conventional approaches. In conclusion, the integration of bioinformatics and pharmacogenomics plays an essential role in strengthening TB treatment strategies through a personalized, adaptive, effective, and sustainable approach. Nevertheless, its implementation still faces challenges such as high costs, limited infrastructure, and the need for clear regulations regarding the use of patients’ genomic data.

This research is motivated by the role of the Sharia Investment Gallery (GIS) as a student laboratory for learning about investment. Based on the data, the number of investors in the Islamic Investment Gallery from the inception of GIS from 2016 to 2021 is unstable every year and is still relatively low. Even though the FEBI Faculty has good potential in attracting investors because there are so many enthusiasts in the FEBI departments. Low interest and motivation in investing in Indonesia is due to low knowledge and understanding of the capital market. GIS is expected to help foster student interest in investing in the Islamic capital market. The purpose of this study was to determine the role of Gis, both the constraints and solutions faced by Gis in fostering students' interest in investing in the capital market. This research approach uses descriptive method with a descriptive qualitative approach, namely research that seeks to describe a symptom, event, event that is happening now. The method used in this research is to collect data through interviews, observation, surveys, and documentation. The results of the study show the role of Islamic investment galleries (GIS) in fostering student interest in investing in the capital market by carrying out 4 roles, namely first, socialization as an introduction to the world of investment to students and inviting students to invest, second education, namely providing investment knowledge to students, third motivation, namely motivating students by giving examples of people who are successful in investing, the four integrity, namely the management of GiS applies a commitment attitude among the board, consistently carrying out their duties, being responsible, honest and courageous in conveying educational and motivational socialization to students. The internal constraints for Gis are the difficulty of coordinating administrators to be active in activities and the external constraints are the difficulty in getting students to participate in Gis activities and the lack of awareness of students to invest. The internal solution is to always hold monthly meetings to strengthen relationships between administrators and trigger back responsibilities as GIS administrators and the GIS Management also utilizes social media as a promotional medium so that it can be even wider to convey socialization and education to students. Meanwhile, for external solutions, GIS requests lecturer assistance to direct students to participate in all activities held by GIS. As for these 4 roles, the role most expected by FEBI students is the role of motivation. With good motivation given it can trigger students’ interest in investing.
