Data on waste generation in 2024, nationally, in the Special Region of Yogyakarta Province, and in Bantul Regency, consistently show organic waste as the largest component (more than 50%). Based on its source, the largest waste generation (53-75%) comes from households. This community service program aims to increase the participation of households in Trayeman Hamlet, Plered Village, Plered Sub-district, Bantul, in managing their own organic waste. This program is implemented through training for local PKK members. The methods presented are biopore, the covered bucket method, the stacked bucket method, the losida method, and the gallon method so that the community can easily adjust their choices. The training continued with the creation of composting tools, inoculant solutions, and biopore infiltration holes. Obstacles faced in organic waste management are the dependence of some residents on waste collection services. Supporting factors are the high community interest in gardening, the periodic garden utilization and cleanliness competitions held by the local village, and the commitment of PKK administrators to be able to process their organic waste independently.

This study aims to determine the influence of transformational leadership style, physical work environment, and intrinsic compensation on employee performance on CV. Nina Etik Garment Indonesia, a written batik industry operating in Mojokerto. The background of this research departs from the phenomenon of low employee productivity which is allegedly influenced by internal and external factors of the organization. The research method used is a quantitative approach with a census method for all permanent employees totaling 39 people. Data analysis was carried out using Structural Equation Modeling–Partial Least Square (SEM-PLS) based on the SmartPLS 4.1.1.2 application. The results show that only the physical work environment has a significant effect on employee performance. This indicates that the factors of comfort, security, and the feasibility of work facilities have a dominant role in improving employee performance. In contrast, transformational leadership styles and intrinsic compensation have not been shown to have a significant impact. These findings provide an idea that the motivation of employees in the creative industry sector based on local culture such as written batik is more influenced by the real working conditions they face on a daily basis than by a leadership approach or non-financial reward alone. The practical implication of this research is the need for company management to prioritize improving the physical aspects of the work environment, such as lighting, ventilation, cleanliness, and ergonomic workspace layout. By creating a comfortable and supportive work environment, employee productivity and performance can be significantly improved. In addition, although there is no significant effect in this study, leadership style and intrinsic compensation still need to be considered in order to create a balance in the sustainable human resource management strategy and be able to support innovation, creativity, and competitiveness of the company.

During storage and before consumption, grains often experience a decline in quality, nutritional content, and cleanliness due to pest attacks. Botanical insecticides are considered an alternative method to reduce dependence on harmful chemical pesticides. This study aimed to evaluate the effectiveness of three concentrations of silver nanoparticles (AgNPs) synthesized from the leaves of Cymbopogon citratus against Cadra cautella (Walk.) (Lepidoptera: Pyralidae) and their potential as biological control agents. The selection of C. cautella as the test organism was based on the limited number of studies examining this pest. The AgNPs used were synthesized through an eco-friendly method, and their optical and physical properties were analyzed using UV-Vis spectroscopy. The results demonstrated that AgNPs synthesized from C. citratus extract showed high effectiveness in controlling the eggs and second instar larvae of C. cautella. Egg mortality reached 80.3% at a concentration of 40 μg/ml after 24 hours of exposure, followed by 72.9% at 30 μg/ml, and 65.8% at 20 μg/ml. In contrast, the control group showed no egg mortality. Similarly, larval mortality rates were 74.9%, 65.8%, and 60.2% for concentrations of 40 μg/ml, 30 μg/ml, and 20 μg/ml, respectively. These findings indicate that higher concentrations of AgNPs lead to greater mortality in both eggs and larvae. This study highlights the potential of green-synthesized AgNPs from C. citratus leaves as an effective and eco-friendly biopesticide. Their significant impact on egg and larval mortality suggests that they can be developed as an alternative pest control strategy in stored grains, thereby reducing reliance on conventional chemical pesticides that are detrimental to human health and the environment. Further research is recommended to explore their long-term efficacy, safety, and integration into sustainable grain storage management.

Tawangsari Hamlet, Tejosari Village, Ngablak District, Magelang Regency, faces serious waste management challenges, reflected in the high daily waste production and the inactivity of waste banks post-COVID-19. To address this issue, the Tidar University Community Service Program (KKN) was implemented, aiming to improve environmental cleanliness through active community participation.

Schools are not only institutions for the transfer of knowledge but also environments that play a crucial role in shaping students’ behavior and instilling positive habits, one of which is environmental care. One form of environmental concern that can be cultivated from an early age is the discipline of disposing of waste properly. However, SD Negeri Jambewangi, located in Dusun Pesantren, has not yet fully implemented effective waste sorting practices. Waste disposal is still carried out without distinguishing between organic and inorganic waste, which may have negative impacts on the school environment. To address this issue, community service activities were carried out by KKN students from Universitas Tidar through outreach programs and the distribution of sorted waste bins. The socialization activity applied the Extend Parallel Process Model (EPPM) communication strategy using a Severity Model approach, which emphasized the dangers and consequences of improper waste management practices. During the sessions, students were encouraged to discuss and identify various types of waste, as well as the potential environmental and health impacts associated with them. Direct practice was also provided by encouraging students to actively participate in sorting waste before disposal into the designated bins. The implementation of this program showed a positive impact, as students demonstrated an increased understanding of waste management and began to practice sorting waste more consistently. The provision of separate bins for organic and inorganic waste further facilitated this new habit. It is expected that the discipline of sorting and properly disposing of waste will continue to be applied by students, teachers, and the entire school community. Such continuous practices can foster collective awareness, contribute to maintaining environmental cleanliness, and provide long-term benefits not only for the school but also for the surrounding community.

This study was conducted to examine the influence of ticket prices, facilities, and location on visitor satisfaction at Tirta Bening Swimming Pool. The approach used was quantitative with data collection through primary and secondary sources. The study population consisted of all visitors to Tirta Bening Swimming Pool. Data analysis techniques used included validity testing, reliability testing, classical assumption testing, multiple linear regression analysis, and hypothesis testing. The results of the study indicate that partially, the three variables—ticket prices, facilities, and location—influence visitor satisfaction, as indicated by the t-test results. Meanwhile, based on the F-test, all three simultaneously also have a significant influence on the level of visitor satisfaction. More specifically, the facility variable has a dominant influence on visitor satisfaction. This indicates that comfort, cleanliness, completeness of facilities, and the quality of service provided by the management significantly influence visitors' perceptions of their experience at the swimming pool. Affordable ticket prices are also a major attraction, especially for families and student groups seeking cost-effective recreational alternatives. Meanwhile, the strategic and easily accessible location is also an added value, especially for visitors from the surrounding area. The implications of these findings are the importance of regularly upgrading and maintaining facilities, as well as providing additional services such as a cafeteria, comfortable changing rooms, and responsive security personnel. Management is also advised to periodically evaluate ticket pricing to maintain competitiveness while still supporting operational and service development. Furthermore, location promotion through social media and digital platforms can also expand visitor reach. This research provides an important contribution to the development of tourism destination marketing and management strategies based on visitor needs and satisfaction.

Limited sanitation facilities among street vendors, particularly those selling meatballs, chicken noodles, and porridge, often pose a problem that impacts food safety. One common practice is repeatedly washing bowls and spoons with just a bucket of water, followed by drying the utensils with a cloth. This contaminated water can transmit pathogenic microorganisms that cause foodborne illnesses, increasing the risk of health problems for consumers. This problem requires a practical solution that street vendors can implement, taking into account limited space, mobility, and operational costs. This community service activity used a pre-experimental design method with a simple technological engineering approach to improve the sanitation of tableware. The innovation developed was a portable bowl washer made from used mineral water gallons, modified to be mobile, efficient, and water-efficient. The manufacturing process included design, assembly, testing, and evaluation with street vendors. Success was measured by observing the level of cleanliness of the tableware before and after use, as well as assessing the level of satisfaction and ease of use by the vendors. The results showed that the implementation of this portable sanitation device increased the effectiveness of tableware washing, reduced the repeated use of dirty water, and minimized the risk of cross-contamination. Partnering vendors stated that the device is practical, lightweight, and doesn't disrupt their sales activities. They hope this innovation will be replicated by other vendors and that local governments will consider implementing it as a standard for mobile food sanitation. This effort will not only improve the hygiene of eating utensils but also contribute to preventing foodborne illnesses in the community.

Pempek is a traditional Indonesian food that is widely loved by people because of its delicious taste and easy availability in various regions, especially in coastal areas. However, although pempek is made from ingredients that are generally safe for consumption, the unhygienic production process has the potential to cause contamination by pathogenic bacteria. The process of making pempek involves many hands, unsterile processing, and inadequate storage can increase the risk of bacterial proliferation, especially in food served by street vendors. This study aims to identify the presence of pathogenic bacteria in pempek sold by street vendors around the campus environment. By using sample dilution methods, inoculation onto Nutrient Agar (NA) media, as well as colony morphology differentiation and Gram staining, this study successfully identified several pathogenic bacteria that have the potential to harm health. The bacteria found included Staphylococcus sp., known as a pathogen causing food poisoning, E. coli which can cause gastrointestinal disorders, and Pseudomonas sp. which can cause skin and respiratory infections. Based on the results of this study, it is important for local food producers to maintain cleanliness and ensure hygienic production processes so that the food sold is safe for consumption. Furthermore, food quality monitoring by authorities and education for producers on the importance of hygiene in food preparation need to be strengthened to prevent the risk of foodborne illnesses. Furthermore, regular inspections of food sold by street vendors are crucial to ensure it is free from harmful microbial contamination. Implementing proper sanitation procedures at every stage of pempek production, from selecting raw materials to serving, can minimize the risk of microbial contamination.

Amidst increasing guest expectations for accommodation cleanliness and comfort, the implementation of standard operating procedures (SOPs) in housekeeping services has become a crucial aspect in the hospitality industry. Good guest room cleanliness not only enhances comfort but also strengthens an accommodation's image and reputation. One example of an accommodation that implements a room cleaning SOP is Palm Homestay Kuta Lombok. This study aims to analyze the implementation of the SOP for guest room cleaning at Palm Homestay Kuta Lombok, evaluate the extent to which the SOP is implemented, and identify problems encountered and possible solutions for improvement. The research method used in this study is a qualitative approach with data collection techniques through observation, interviews, and documentation. Observations were conducted directly in the field to assess how the room cleaning SOP is implemented, while interviews were conducted with housekeeping staff and management to obtain their perspectives on obstacles and solutions encountered in the cleaning process. The documentation collected includes written SOPs and supervisory notes conducted by management. Based on the research results, the implementation of the room cleaning SOP at Palm Homestay Kuta Lombok can be said to be running quite well. However, several obstacles remain, such as inappropriate placement of amenities, inconsistent dusting methods, and limited cleaning equipment. These obstacles can impact the quality of room cleaning and guest comfort. Although improvements have been made, such as regular supervision and more consistent use of cleaning equipment, employee training still needs to be maximized. As a solution, this study recommends optimizing the budget allocation for employee training, with the aim of improving staff skills and understanding of the implemented SOPs.

Drinking water is a basic human need that must meet health requirements to be suitable for direct consumption without causing health risks. Drinkable water must be free from various contaminants, both physical, chemical, and microbiological that can harm the human body. One of the sources of drinking water that is widely used by the community is refillable drinking water (DAMIU), which is now growing due to its affordable price and ease of access. However, the water quality from DAMIU is often a concern due to potential contamination due to sanitation that does not meet standards. This study aims to analyze the sanitary conditions of the refillable drinking water depot (DAMIU) and assess the quality of drinking water based on physical, chemical, and microbiological parameters in the working area of the Punti Kayu Health Center, Palembang. A total of 15 DAMIU are the object of research that are examined through laboratory tests and direct observation of the sanitary conditions and equipment of the depot. The results showed that all DAMIU (100%) had met the general sanitation requirements, such as room cleanliness, equipment, and workers. However, microbiological testing found that 33.4% of the water samples contained E. coli and Coliform bacteria, indicating the presence of contamination. In addition, all samples (100%) did not meet the ideal drinking water pH requirements, and as many as 40% of the samples had aluminum content that exceeded the threshold set by the Indonesian Minister of Health. From these findings, it can be concluded that although the sanitary conditions of DAMIU are relatively good, the quality of the drinking water produced still requires serious attention.
