Abstract

Food security has become an increasingly urgent global issue as the impact of climate change and the global food crisis intensify. Indonesia, as an agrarian country, has great potential to strengthen its food system to be self-sufficient and sustainable, one of which is through the empowerment of local farmer groups. This article discusses efforts to enhance food security through agricultural product diversification by leveraging untapped local potential, specifically the processing of rubber tree (Manihot glaziovii) tuber skins. Empowerment activities were conducted with the Sutra Alam Gunung Sewu group in Gunungkidul Regency, DIY, which had previously only utilized the plant's leaves as silkworm feed. The tubers and bark of this tree, which are nutrient-rich but contain high levels of cyanide acid, have the potential to be developed as an alternative food source if processed properly. The empowerment program was implemented to enhance the group's capacity to process the tuber bark into useful products. Evaluation was conducted using pre-test and post-test instruments to measure improvements in members' knowledge and skills. The results showed a 120% increase in general knowledge and an 84% increase in understanding of information regarding the potential of local food and the processing of risky materials into safe consumption. This initiative contributes to food diversification and the economic empowerment of local communities in supporting national food security.

Abstract

Sacha inchi oil is a seed-derived oil from the Amazon Rainforest, known for its high nutritional value and bioactive compounds. It contains essential fatty acids such as omega-3 and omega-6, along with tocopherols, polyphenols, carotenoids, and phytosterols, making it beneficial for health applications. Due to its nutritional and therapeutic properties, sacha inchi oil has gained significant attention in the food, cosmetic, and pharmaceutical industries. This study contributed to identify and analyze the bioactive compounds in sacha inchi oil extracted from seeds obtained in Central Java, Indonesia. The extraction process was carried out using a hot pressing method, followed by qualitative phytochemical analysis and LC-HRMS identification. The phytochemical tests confirmed the presence of flavonoids, alkaloids, tannins, phenolics, saponins, steroids, and terpenoids, all of which contribute to antioxidant, anti-inflammatory, anticancer, and antimicrobial properties. However, LC-HRMS analysis did not detect flavonoids, tannins, and saponins, possibly due to their low concentration, matrix effects, or degradation during analysis. These findings highlight sacha inchi oil’s potential in nutraceutical, pharmaceutical, and cosmetic industries. Its bioactive compounds suggest its potential use in functional foods, dietary supplements, and therapeutic applications, particularly in preventing oxidative stress-related diseases. Further research is recommended to optimize extraction techniques, improve compound stability, and evaluate its bioavailability and long-term health benefits. The presence of bioactive compounds indicates that sacha inchi oil can be a valuable functional ingredient for health and medical applications, contributing to sustainable and natural health solutions.

Abstract

The demand for cosmetics in Indonesia is quite high so cosmetics can now be said to be a primary need. Therefore, various cosmetic products have emerged that are cheap and provide instant results but ignore the health aspects of the user. Several cosmetic products make a breakthrough by using natural ingredients. One natural material that can be used is microalgae which can produce bioactive compounds and has a relatively faster production process compared to other natural materials. In this research, the microalgae used were Chlorella sp. and Spirulina sp., and Sargassum sp. This research aims to make a serum based on the Chlorella sp., Spirulina sp. and Sargassum sp. microalgae. The research results showed that the standard testing of simplicial facial serum extracts of Spirulina sp., Chlorella sp., and Sargassum was by SNI No. 16-4399-1996.[ASUS1] [AP2]  All the metrics analyzed, such as organoleptic characteristics, pH, specific gravity, viscosity, active compounds, and microbiological contamination, have successfully fulfilled the required requirements in SNI no. 16-4399-1996.. The results of antioxidant activity testing showed that Chlorella sp. had higher antioxidant activity than the other three types of samples. However, the antioxidant results obtained are still very low and relatively weak, which means this serum does not fully contribute to antiaging. Further research needs to be carried out to obtain serum from microalgae with high levels of antioxidants, including by using fresh simplicia, elevated algae concentration or optimizing the operating conditions.     [ASUS1]Please add short information about the main results, whether the serum satisfies the standard or not, which parameters, etc. [AP2]Has been added

Abstract

The volume of municipal waste has become a national problem so far, so a solution is needed to reduce the waste problem. One solution to reduce the volume of municipal waste is to burn waste. However, the combustion needs to be designed to take advantage of the heat generated by combustion. In this study, the process of burning waste with various types of waste materials was carried out. The heat of burning waste is used to evaporate 1 liter of seawater and the seawater vapor is cooled to produce distilled water. The volume of distilled water and the precipitated salt were weighed. The results of the research from the variation of 6 types of waste materials obtained that the type of clothing waste material gave the fastest time, which was 43.75 minutes, the amount of distilled water was 931 ml, and salt deposited as much as 30 grams. The test results on distilled water showed that almost all parameters met the requirements of drinking water and obtained a salt content of 84%. Further processing by adjusting the hardness is needed to process distilled water into clean water and the addition of iodine can be considered to produce iodized salt.

Abstract

Using waste cooking oil as an alternative fuel can reduce dependence on fossil fuels and address the problem of waste oil. This study aims to analyze the effect of the flow rate ratio of air and waste cooking oil on combustion characteristics and efficiency of domestic furnace. The experiment started with fuel characterization, including density, viscosity, flash point, and calorific value tests. The combustion process was carried out by varying the fuel and airflow to the furnace. Experiments included flame temperature measurements, water boiling tests, and measurements of heat uptake efficiency by the pot water. The results showed that the highest combustion temperature of 925.55℃ was achieved at an airflow rate of 21.3 m/s with a fuel flow rate of 1.05 L/hour. The flue gas emission temperature and furnace efficiency increased as the airflow rate and fuel discharge increased. The ratio also produces the fastest water boiling time of 2 minutes with the efficiency of heat uptake by water in the pot of 34.12%. The highest heat uptake efficiency by the water in the pot was obtained at the ratio of used cooking oil discharge of 0.6 L/hour with an airflow rate of 12.1 m/s at 43.12%. These results demonstrate the potential of waste cooking oil as an alternative fuel for efficient domestic combustion devices, with proper air supply to achieve optimal combustion.

Abstract

Waste is a problem that has not been resolved properly in Indonesia. Likewise, in Sorogenen II village, Kulon Progo district, where the majority of livelihoods are farmers, gardeners and traders related to agriculture and plantations, there is still not much information on the management of organic waste, especially crop and fruit waste. Several efforts to utilize waste have been made. One way to utilize waste from fresh fruit peels is to ferment it with molasses so that after 3 months it will become eco enzyme. This enzyme liquid has been used as a natural fertilizer, pest repellent, and cleaning liquid. The training conducted by volunteers of the eco enzyme archipelago, PKK group and UAD community service team took place in Sorogenen II village, Kulon Progo district. In addition to the delivery of how to make eco enzyme, the utilization and business opportunities of eco enzyme were also delivered in the training. A showcase of eco enzyme products was also held at UAD and many visitors were enthusiastic about making eco enzyme independently.

Abstract

Plastic waste has become a significant problem of environmental pollution in recent decades. The nature of plastic waste is complicated to decompose; it has worsened the environmental situation, especially if it is not taken seriously immediately. One approach that can be taken to overcome this problem is to provide counseling to the public so that they do not dispose of plastic waste carelessly. The community service program is a forum for academics to participate and provide counseling about the management of plastic waste. The purpose of this community service program is to counsel the Panjangrejo community about how to manage plastic waste properly. This counseling program began with discussions with the Panjangrejo sub-district officials and related parties, then continued with planning the timing of the extension. Residents and community elements are fully involved, so this program can run smoothly. The counseling program was carried out in three villages, namely the villages of Semampir, Gunung Puyuh, and Krapyak Wetan, and this program was held at night from 20.00 WIB to 22.00 WIB. The outreach results showed that people's knowledge about the dangers of plastic waste and how to manage it could be significantly improved (p < 0.05). In general, this extension program successfully increased respondents' knowledge from "not knowing" to "knowing better" about the dangers and how to manage plastic waste.

Abstract

Silk fabric is still one of the exclusive fabrics sought after, especially by women. However, at the end of this decade, silk fabric production decreased. The decreasing availability of silk fabric raw materials influences the decline in silk fabric production. The availability of raw materials for silk fabric cannot be separated from the number of silkworms (Bombyx mori L.) cultivated as a cocoon producer which is later spun into silk yarn.  Gunung Sewu is a silkworm cultivation group based in Rongkop District, Gunungkidul Regency, Yogyakarta, which has successfully conditioned silkworms to consume rubber cassava leaves as their main feed. Currently, sales of cultivation products are still in the form of ready-spun cocoons and fried ungkrung (inside of cocoons). The silk fabric factory is also willing to buy cocoons that have been spun into silk thread at a higher price. However, the Gunung Sewu group does not yet own a spinning wheel, so it cannot carry out the spinning process independently. On the other hand, derivative products in the form of ungkrung are still processed by frying. Even though there are still many foods that can be developed from silkworm ungkrung processed ingredients. In this community empowerment program, Gunung Sewu group capacity-building activities were carried out by applying spinning machines and identifying the content of ungkrung. The results obtained from the spinning machine application activity were that the turnover of the Gunung Sewu silkworm cultivation group increased by 200%. While the activity of identifying the content of ungkrung showed a significant increase in the knowledge of group members.
