Maggenrang Village is a village located in Kahu District, Bone Regency. One of the hamlets in Maggenrang Village that stands out is Pettungnge Hamlet, where maja plants grow in abundance. Each house in this hamlet has around 3-4 maja trees which are used as hedges. However, maja fruit in Pettungnge Hamlet is left lying around or even used as toys by children. Most of the maja fruit that falls from the trees is also thrown into the river because it has an unpleasant aroma. The main problem related to maja fruit in Pettungnge Hamlet is the lack of public knowledge in using it. Maja fruit has a taste that tends to be bitter and has a strong smell, especially old fruit1. In fact, maja fruit has great potential to be used as raw material for making hand washing soap as a sanitation product. The solution offered by the Proposing Team is to transform maja fruit into environmentally friendly hand washing soap. Currently, hand washing soap on the market contains chemicals that are not good for the environment and skin health. Using natural ingredients such as maja fruit as an alternative can help reduce the negative impacts of chemical soap. Maja fruit contains saponin compounds which cause this fruit to foam when mixed with water. Therefore, maja fruit can be processed into safer and more effective hand washing soap. By producing hand washing soap from maja fruit, people can increase their knowledge and skills in producing products of high economic value. Apart from that, it is also in line with the village's sustainable development goals (SDGs), especially in creating healthy, prosperous and environmentally conscious villages.

Lurik cloth is a textile product that is very popular with the public. Its existence boosts the community's economy. However, on the other hand, the process of making lurik cloth produces liquid waste that can damage the environment, ecosystems and is harmful to human health. This study aims to reduce the color intensity in textile industry liquid waste using the electrolysis method to improve the quality of wastewater so that it is suitable for disposal. This study used textile waste from the Lurik industry; Klaten; Central Java as a sample material. The parameters observed were color intensity, pH, Total Dissolved Solids (TDS) and Total Suspended Solids (TSS). After the electrolysis process, the solution was analyzed qualitatively and quantitatively with a UV-Vis Spectrometer and TSS value analysis. The results showed that the electrolysis method was effective in reducing pollution parameters in liquid waste. At a voltage of 15 volts for 90 and 120 minutes, the pH value of the liquid waste decreased to 12.17%. In addition, there was a decrease in TDS and TSS levels. The highest TDS level decreased to 23.16% at a voltage of 15 volts and a contact time of 120 minutes, while TSS decreased by 7.36% under the same conditions. Based on these results, researchers provide practical recommendations to the textile industry in the management of lurik fabric dyeing liquid waste to apply the electrolysis method as a sustainable and environmentally friendly liquid waste processing strategy. Thus, this study is expected to provide a positive contribution in efforts to reduce liquid waste pollution and environmental preservation.

Soil degradation in Indonesia due to excessive use of chemical fertilizers leads to a decline in soil quality, increased toxicity, and environmental damage, which negatively impacts crop productivity. This study aims to synthesize sodium silicate from gasified rice husk ash as an alternative organic fertilizer and to determine the optimal operational conditions for the synthesis process. Organic fertilizers have the potential to improve soil structure and reduce compaction, while nano-fertilizer technology offers efficiency in nutrient release. The research was conducted in the Chemical Engineering Operations Laboratory at Universitas AKPRIND Indonesia, with varying soaking times in a 2 M NaOH solution of 45, 60, 75, and 90 minutes. The results indicate that the optimal soaking time for sodium silicate synthesis is 45 minutes, yielding 0.6 grams of sodium silicate with a yield of 12%. The increase in NaOH concentration is associated with the solubility of sodium silicate, but the results show the presence of unreacted excess NaOH. This study underscores the importance of optimizing soaking time and NaOH concentration to enhance the efficiency of sodium silicate production from rice husk ash and contributes to the development of more environmentally friendly and sustainable organic fertilizers within the context of modern agriculture. Furthermore, this research has the potential to open opportunities for farmers to reduce their dependence on chemical fertilizers, thereby supporting environmental sustainability. The implementation of sodium silicate as an organic fertilizer can improve soil health and crop quality. Additionally, the findings are expected to contribute to sustainable agricultural policies in Indonesia. Finally, the utilization of rice husk ash as a source of sodium silicate will enhance the added value of agricultural waste and support more efficient natural resource management.

This research aims to explore the effects of varying the mass of the KOH absorber and natural zeolite catalyst on the pyrolysis yield of empty palm fruit bunches (EFB) using a microwave reactor. EFB was chosen as the feedstock due to its abundant availability and potential as a renewable energy source. The use of a microwave reactor enables faster heating of EFB and improved temperature control. The pyrolysis process was carried out with a configuration of two separate reactors: a microwave reactor to pyrolyze EFB with KOH as an absorber to absorb microwaves and convert them into heat, and a catalyst reactor with heating provided by an oven. The operating temperature for the microwave reactor was set at 450°C, and for the catalyst reactor at 400°C. The methodology involved varying the mass of KOH (0%, 50%, 100%) and zeolite (0%, 10%, 20%, 30%) to evaluate their effects on pyrolysis product distribution. The results showed that adding KOH as an absorber improved heating efficiency, with a higher KOH mass (100%) tending to increase gas production. The addition of zeolite also proved to enhance bio-oil yield, especially under conditions of 50% absorber and 30% zeolite, which achieved the highest yield of 34.8%. The optimal combination of KOH absorber and zeolite catalyst shows great potential in increasing bio-oil yield, thus supporting the use of EFB as a sustainable alternative energy source.

UMKM MAQ is a home industry that produces handicraft products from resin and wood waste located in the Playen Gunungkidul area. In recent months, sales of wall clock products have decreased, only being able to sell 6-9 products compared to previously being able to sell an average of 25 wall clock products per month. This problem is likely to occur because consumers are starting to become bored with previous wall clock models, the unavailability of other models, and the decreasing competitiveness of these products, so it is necessary to develop new wall clock models by considering consumer satisfaction so that MAQ is able to increase the number of wall clock sales again. The aim of the research is to develop wall clock products using the Quality Function Deployment (QFD) and Concurrent Engineering (CE) methods. Both methods are used to identify consumer needs that are linked to process needs. The product process needs with the highest contribution value indicate that these process needs are the focus of development for new wall clock product designs, while the consumer needs attributes with the highest value are things that must be improved to overcome existing problems. The results of the approach using both methods show that the process needed with the highest value is the provision of a new design with a normalized contribution value of 36%, while of the six consumer needs attributes that obtain a contribution value is the response to variations in other sizes with a value of 1.6083.

ABSTRACT
Pineapple is one of the plants that is widely grown on Indonesian plantations. From 2018 to 2022, total pineapple production in Indonesia was 2,149,733 tons yearly. Pineapples are not only used for the fruit but the pineapple leaves can be processed into something with higher economic value. One use of pineapple leaves is as an alternative raw material for textile thread. The process of making thread from pineapple begins with making pineapple fiber. Making pineapple fiber is done by extracting pineapple leaves, and then carrying out a traditional spinning process. In Indonesia, there is still no use of pineapple fiber as raw material for textile yarn in an industrial-scale production process. Therefore, this research aims to assess the suitability of pineapple fiber as a raw material for textiles. In this research, pineapple fiber was mixed with cotton fiber and the production effectiveness was observed. It was found that a mixture of pineapple fiber and cotton fiber with a composition of 45%:55% had the best effectiveness compared to fiber compositions of 14%:86% and 29%:71% with the lowest average number of broken threads, namely 16.33 in 60 minutes. However, the number of thread breaks is still relatively high so it is considered not yet effective or the OE thread production process is not yet running smoothly.
