Concrete roof tiles are an important material in building construction, particularly for roofing work, due to their advantages in terms of strength, durability, and material availability. This study aims to analyze two main physical characteristics of concrete roof tiles, namely bending load and water absorption, using a literature review approach from various previous studies. Bending load refers to the material's ability to withstand bending forces, while water absorption describes the material's capacity to absorb and store water through its pores. These two properties significantly influence the quality and durability of roof tiles in facing external environmental conditions, especially wet-dry cycles and mechanical loads. The results of the literature review indicate that the use of waste as an aggregate substitute in concrete mixes can significantly improve the performance of concrete roof tiles. For example, research using broken roof tiles and ceramic waste as aggregate substitutes successfully increased flexural strength to a range of 12.5–15.0 MPa. Meanwhile, variations in water absorption were recorded in the range of 4%–8%, depending on the material composition and production method. This proves that the use of recycled materials not only supports sustainability but also improves the mechanical and physical properties of concrete roof tiles. Overall, this study underscores the importance of material innovation in concrete roof tile production, particularly utilizing waste as an alternative aggregate. However, further research is needed to explore the best combination of materials and production techniques for producing high-quality, efficient, and environmentally friendly concrete roof tiles.

Overall, this program had a positive impact by fostering greater environmental concern and became an initial step toward building a sustainable waste management culture in Buniwangi Village.

The presence of scattered waste in the environment has a significant impact on both environmental sustainability and human health. In Indonesia, the accumulation of waste has reached alarming levels, amounting to approximately 175,000 tons per day, or the equivalent of 64 million tons annually. Household activities are one of the main contributors, producing a wide variety of waste, including organic and non-organic materials. Poto Village is among the areas receiving particular attention regarding this issue due to the challenges it faces in waste management. Improper management of waste not only leads to air, water, and soil pollution but also increases the risk of various health problems within the community. One of the programs designed to address this problem is the 3R program, which emphasizes three main principles: reduce, recycle, and reuse. The purpose of this community service initiative is to improve public knowledge and awareness of effective waste management through the application of 3R practices. The activities were carried out in three main stages, namely preparation, education, and discussion through a question-and-answer session. The process began with a socialization activity that introduced the objectives, purposes, and sustainability aspects of waste management efforts in the village. The educational session was attended by 30 participants, consisting of housewives, farmers, and entrepreneurs, who represented key groups within the community. Furthermore, interviews with local cadres revealed that waste is collected weekly by garbage trucks, indicating the village’s commitment to environmental management. Participants responded enthusiastically throughout the educational sessions, showing a strong interest and positive reception toward the information provided. As a follow-up step, future activities could include hands-on training in waste management using available media and tools, which would allow participants to apply the concepts learned in a practical and sustainable manner.

This community service program was implemented to address the needs of farmers in Kalicaah Village, Tanjung Jaya Village, Panimbang District, for an affordable, simple, and user-friendly fertilizing tool.

To overcome this issue, the program team designed a solid fertilizer spreader using appropriate technology, constructed from recycled materials such as PVC pipes and used water gallons. This innovation was aimed at creating a sustainable, low-cost solution for the local agricultural community. The program’s implementation involved several key activities, including identifying the farmers' challenges, conducting assembly training sessions, demonstrating the tool’s use, and running direct field trials in local farms. The results showed that the use of the newly developed fertilizer spreader led to a 45% reduction in the time spent applying fertilizer, which directly contributed to more efficient farming practices. Additionally, there was a significant reduction in physical complaints, particularly lower back pain, which had been a common issue due to the manual labor involved in fertilizing. The tool proved to be easy to construct, requiring minimal technical knowledge, and the farmers were able to adopt the technology independently. The high rate of adoption among farmers further emphasizes the tool’s potential for widespread use. The success of this program also suggests that this simple, affordable technology could be replicated in other agricultural regions, benefiting more communities by improving work efficiency, reducing physical strain, and fostering a sustainable approach to farming practices.

The problem of household organic waste management, especially kitchen waste, is still an environmental challenge that has not been handled optimally. In fact, this waste has great potential to be used as environmentally friendly products. One solution that can be applied is the manufacture of eco-enzymes, which are fermented liquids from organic waste that function as a substitute for synthetic chemicals in various household and agricultural purposes. This community service activity aims to increase the awareness and skills of residents in managing organic waste through the creation of eco-enzymes as a tangible form of applying the 3R (Reduce, Reuse, Recycle) principle. The activity was carried out in Kedu Village by involving PKK women, PSRT members, the Farmer Women Group (KWT), and housewives. The methods used include counseling on the impact of household waste and the benefits of eco-enzymes, as well as direct practice of making eco-enzymes accompanied by Mrs. Faila and students of the Real Work Lecture (KKN) of Tidar University. The implementation process includes sorting kitchen waste, mixing fermentation ingredients, and monitoring yields during the incubation period. The results of the activity show that the community is able to understand the concept and techniques of making eco-enzymes well. The active participation of residents in hands-on practice reflects increased knowledge and skills in independent organic waste management. In addition, this activity encourages the formation of new sustainable habits in utilizing household waste, while reducing dependence on synthetic chemicals. Thus, this service makes a positive contribution to environmental conservation efforts and local community empowerment through educational and applicative approaches.

This research aims to explore the potential of paper waste as a recycled material that can be transformed into economically valuable products through a philanthropic approach focused on community empowerment and environmental sustainability. Paper waste is a type of waste whose volume continues to increase due to high paper consumption in various sectors. Without proper management, this waste has the potential to negatively impact the environment, such as soil and water pollution. Therefore, innovative strategies are needed to transform paper waste into new products that are not only environmentally friendly but also have market value. Through a community-based recycling program, this research emphasizes the importance of community involvement, particularly low-income groups, in every stage of the production process. The resulting creative products, such as handicrafts, decorative materials, and household items, not only extend the life cycle of paper but also open up new economic opportunities for the community. Profits from the sale of these products are allocated to fund social programs, including education, skills training, and other empowerment activities aimed at improving community well-being. The research results show that despite challenges in terms of limited technology, market access, and human resource capacity, paper recycling programs still have promising prospects if supported by various parties, including the government, non-governmental organizations, and the private sector. This support can include the provision of simple technology, entrepreneurship training, and effective marketing strategies. Thus, this paper recycling initiative is not only a solution to reduce waste but also a sustainable socio-economic empowerment model, providing dual benefits for the environment and society.

Contemporary art continues to expand its definition, blurring the boundaries between functional objects and fine art. This practice-based research explores the potential of recycled materials in visual art creation, using a tricycle as the primary medium. Using a mixed-media approach, primarily utilizing recycled metal and plate, along with recycled components such as drills and old water pumps, this project aims to transform the tricycle from a mobility object into a work of fine art. This concept intentionally blurs functional aesthetics, emphasizing freedom of expression and uniqueness of form, and reflecting a dialogue between the past and the present through recycled materials. Through a case study of the work "The Bully," this paper explores how a writer's personal trauma can be sublimated into a powerful artistic expression, forming a visual narrative of power, intimidation, and artistic revenge. This research also adopts an Artistic Research methodology to examine the creative process holistically.

Plastic waste, particularly High-Density Polyethylene (HDPE), poses a serious threat to the environment due to its extremely long decomposition time. One effective recycling method is the extrusion process, in which process parameters such as nozzle diameter and heating temperature significantly affect the production rate and the quality of the resulting filament. This study aims to analyze the effect of nozzle diameter and heating temperature on the production rate and diameter uniformity of recycled HDPE plastic filament. The method used is an experimental approach with a quantitative design, utilizing a single-screw type extruder machine. The tested parameter variations include two nozzle diameters (1.75 mm and 2.85 mm) and three temperature levels (200°C, 240°C, and 280°C). The results of the analysis, using factorial ANOVA and control charts, show that both parameters significantly influence production performance. The highest production rate, approximately ±1.0 kg/hour, was achieved with the 2.85 mm nozzle and 280°C temperature combination, while the combination of the 1.75 mm nozzle and 200°C temperature produced the most consistent filament diameter and the best quality, with a resulting diameter of 2.84 mm, which is very close to the target of 2.85 mm. Higher temperatures increase flow rate due to decreased viscosity, but also carry the risk of thermal degradation. This study provides practical guidelines for optimizing the HDPE recycling process through extrusion.

This study analyzes the use of non-standard words in a thesis entitled "Effectiveness of Waste Management Based on Reduce, Reuse, Recycle (TPS 3R) Waste Disposal Sites at TPS Jokotole, Barurambat Timur Village, Pademawu District, Pamekasan Regency". The use of language is an essential thing in communicating, both orally and in writing to convey messages and information so that they are conveyed effectively. However, language errors are often found, especially the use of non-standard words, even by someone who has a deep understanding of Indonesian language rules. The use of standard language is very important to avoid misunderstandings, especially in the context of scientific writing such as theses. This research method uses a descriptive qualitative method with data collected then analyzed, classified, and evaluated standard and non-standard vocabulary based on KBBI. The results of this study indicate that many uses of non-standard words include errors in phonology, morphology, use of the preposition "di", punctuation, and non-standard spelling errors, as well as word wasting. These errors are mostly caused by habits, the influence of foreign languages, and a lack of understanding of standard language rules. The research findings highlight the importance of understanding the application of standard language rules in scientific writing to improve the quality of students' writing.
