This program is designed to provide hands-on training, resources, and long-term support to individuals and families, especially women and youth, in rural areas. By equipping participants with the knowledge and tools necessary for successful goat rearing, the program not only creates opportunities for additional income but also strengthens food resilience and self-sufficiency at the grassroots level. This community service program employs a participatory and sustainable development approach to implement goat farming as a tool for empowerment and livelihood improvement. The methodology consists of five main phases: community assessment, participant selection, training and capacity-building, implementation, and monitoring & evaluation. The Micro-Livestock and Macro-Impact program demonstrated that small-scale goat farming can serve as a powerful tool for community empowerment, particularly in rural areas with limited income sources. Through training, resource provision, and cooperative support, participants significantly improved their knowledge, increased their household income, and began to experience the benefits of sustainable livestock management. The success of this program highlights the potential of micro-livestock farming to serve as a replicable and scalable model for rural development. It shows that even small agricultural interventions, when paired with training and community engagement, can lead to measurable improvements in food security, income generation, and social empowerment.

Conceptual study on gap distance between multiple floating structures system was related to the effect of wave particle motion on structure motion. The evaluation on the gap distance between floating structures is an important study for multiple floating structures system especially for deep water liquefied natural gas, LNG exploration because the small gap distance between floating structures is needed to guarantee the effectiveness of LNG transfer. This conceptual study only discussed the effect of wave particle motion to the varying of gap distance between structures based on theoretical point of view. The expected result was generated by simple harmonic motion equation but it is no been validate in this paper. The expected result shown that the wave length and the structures initial gap distance give a significant effect to the minimum gap distance can be achieved by two floating structures. The mentioned minimum gap distance in this paper mean minimum distance between two floating structures achieved due to surge motions induced by wave. In addition, the comparison to various selected case found that at the condition where one structure face wave crest and other structure face wave trough will caused closest minimum gap distance between floating structures but minimum gap distance will be the largest if both structures face wave crest and wave trough at simultaneously. Therefore, proper selection of initial gap distance for different ocean condition can help to avoid crashing happen on structures when experience wave induced motion.

Prediction of resistance of ship level ice is very important in initial stage of ship design due to related to propulsion and engine power of a ship. As model scale test is very expensive therefore an accurate tool is required to predict the resistance of a ship in ice. A semi empirical method to predict ship resistance in level ice based Koto method was presented. The ship resistance consisted of ice breaking force due to flexural strength of ice, submersion force due to buoyancy, friction force contact between ice and hull and loss momentum force due to collision. The simulation results were verified with experimental data of three icebreakers: MT Uikku, Hellay and Araon. The method was also compared with other empirical methods: Lindqvist, Riska, Keinonen and Jeong. It was founded that the average errors using the proposed method was 3 % for MT Uikku, 0.3 % for Hellay and 0.4 % for Araon.

This study examines the percentage of Indonesian households accessing the internet in the past three months, disaggregated by location, during the period 2015–2017. Using secondary data from the National Socio-Economic Survey (SUSENAS) conducted by the Central Statistics Agency (BPS), the study applies descriptive statistics to identify access patterns and chi-square tests to evaluate potential relationships between household conditions and internet access location. The findings show a steady increase in household internet access over the three-year period, with home-based access emerging as the most dominant and growing mode of connectivity. Conversely, access via mobile vehicles declined, while internet use at workplaces and public facilities remained low. Chi-square analysis indicates no significant relationship between household conditions and access location. These results highlight the increasing reliance on household internet access and its potential role in supporting learning and digital literacy in Indonesia. However, persistent disparities across regions and socio-economic groups suggest that policies must go beyond infrastructure expansion to address issues of affordability, inclusiveness, and digital literacy. This study contributes to the literature on digital inclusion and provides implications for policymakers, educators, and stakeholders in advancing equitable access to education in the digital age.

The increasing demand for functional and health-oriented dairy products has positioned goat milk agro-enterprises as a promising business sector, particularly in emerging economies. Despite this potential, many goat milk businesses face persistent challenges related to production inefficiency, high operational costs, and limited scalability. This study aims to examine the impact of smart processing machines on business efficiency in goat milk agro-enterprises. Using a quantitative approach, data were collected from small and medium-sized goat milk processing enterprises and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results reveal that smart processing machine adoption has a positive and significant effect on business efficiency, including cost efficiency, productivity, and operational effectiveness. The findings indicate that smart processing machines function not merely as technological tools but as strategic business resources that enhance operational performance and competitiveness. This study contributes to the business and agribusiness literature by providing empirical evidence at the production-machine level and highlighting the strategic value of smart manufacturing technologies in small-scale agro-enterprises. The findings offer practical insights for business owners, policymakers, and technology developers in promoting sustainable and efficient goat milk processing businesses.
