Pre-ekstraksi alginat dari alga coklat dengan pelarut asam membutuhkan reaktan dan air dalam jumlah banyak, serta menghasilkan mengeluarkan banyak limbah. Penelitian ini bertujuan untuk mengoptimalkan penggunaan pelarut asam dengan melakukan penggunaan pelarut secara berulang dan mengetahui pengaruhnya terhadap mutu alginat, reduksi kebutuhan air dan reaktan, serta reduksi limbah pelarut. Penggunaan kembali pelarut asam pada proses pre-ekstraksi dilakukan dengan variasi penggunaan pelarut ke 0, 1, 2, 3, dan 4. Rancangan acak lengkap dengan tiga kali ulangan digunakan untuk menentukan pengaruh penggunaan pelarut berulang terhadap mutu alginat. Parameter yang diamati meliputi rendemen, viskositas, berat molekul alginat, kebutuhan air dan HCl, serta limbah pelarut asam. Hasil penelitian menunjukkan bahwa penggunaan pelarut berulang dapat menghasilkan alginat dengan rerata rendemen 26,7%. Penggunaan pelarut berulang ke 0-2 dapat menghasilkan alginat kualitas sedang dengan viskositas 270,9-360,0 mPa.s dan berat molekul alginat 122,04-175,44 kDa. Pre-ekstraksi makrolaga dengan pelarut berulang ke 0-2 dapat menurunkan kebutuhan air 22,2%, HCl 66,7%, dan limbah pelarut menurun 66,7%. Pre-ekstraksi makroalga dengan pelarut berulang mempunyai potensi efisiensi dan perlu dilakukan penelitian lebih lanjut pada skala yang lebih besar. AbstractPre-extraction of alginate from brown algae with acidic solvents requires a lot of reactants and water that produce a lot of solvent wastes. This study aimed to optimize the use of acidic solvents by using solvents repeatedly and to determine the effect on alginate quality, water consumption and reactant, and acid solvent waste. Repeated use of solvents on pre-extraction stage was carried out with variations of 0, 1, 2, 3, and 4 times. A Completely Randomized Design (CRD) with three replications was used to determine the effect of repeated use of solvents on the alginate quality. Parameters observed were yield, viscosity, molecular weight of alginate, water consumption, HCl requirement, and the amount of acid solvents waste. The result showed that the repeated use of solvents in the pre-extraction stage produced alginate with an average yield of 26.7%. Repeated use of solvents of 0 to 2 times produced medium quality of alginate with a viscosity of 270.9-360.0 mPa.s and alginate molecular weight of 122,04-175,44 kDa. Pre-extraction of macroalgae by repeated use of solvents can reduce water consumption 22,2%, HCl 66,7%, and waste solvents 66,7%. Pre-extraction of macroalgae by repeated use of acid solvents was potential for efficiency, and further research is needed for a larger scale extraction process.

The brown alga has bioactive alginate and fucoidan, a potential for raw materials the biorefinery industry with core processing of fucoidan and alginate extraction. The research on sequential biorefinery of fucoidan and alginate was conducted in conventional and hydrothermal methods using a smart pressure-cooker, but the yield of fucoidan is low. The improvement was carried out by extracting fucoidan and alginate using microwave-assisted extraction (MAE). This study aimed to obtain the MAE processing conditions that produced the maximum yield of fucoidan and alginate. The factorial design of 2k was used to determine the effect of MAE processing conditions, i.e. temperature, time, and alga/water ratio on fucoidan and alginate yields. The parameters observed were fucoidan and alginate yield. Data analysis and prediction of first-order model and model accuracy was a regression modelling using a design expert program. The result showed that the elevate of temperature MAE processing to 80 oC,for 20 minutes, and alga/water ratio of 2:20 (w/v) increased fucoidan (4.5%) and alginate (40.6%) yield, but it decreased the yield at 100 oC, for 30 minute, and alga/water ratio of 3:30 (w/v). The equation of the first-order model was quadratic, by wich the model test in curvature was found significant at α=0.05. The MAE sequential biorefinery extraction improved fucoidan and alginate yield and had a potential efficiency for commercialization. The maximum response of fucoidan and alginate yield was obtained from a MAE sequential biorefinery at 80 oC,for 20 minutes,and alga/water ratio 2:20 (w/v); further research is needed to optimizing the process.

Technical Guidance for Freshwater Fish Cultivation at the "Balesemi" Community Self-Help Group in Bakalan Village, Pasuruan Regency Abstract Bakalan Village is located in Purwosari District, Pasuruan Regency, has the potential of an area crossed by a river with abundant water, so it is used to irrigate plants and raise fish including tilapia, tombro or catfish. One of the problems faced is that freshwater fisheries cultivation technology is underdeveloped, knowledge about fisheries is still quite low, and the use of production tools and infrastructure is still simple. The low knowledge of technology in cultivation causes production activities not to run continuously. The activity partner is the Community Self-Help Group (KSM) "Balesemi" in Bakalan Village. This activity aims to improve the knowledge and skills of partner groups in order to maintain production continuity by implementing tarpaulin pond technology as a cultivation medium. Activities start from the preparation stage, socialization, implementation to mentoring. The preparation stage is by means of surveys and interviews, approaching and identifying problems, and discussing together about solving problems. The implementation stages of the Technical Guidance include: 1) Preparation of ponds, 2) Selection of seeds, 3) Spreading seeds, 4) Selection of quality feed; 5) How to harvest and post-harvest. The next solution is to provide assistance in the form of tarpaulin pools that can be used for better fish farming. Evaluation of success is carried out through survey results and questionnaires. The survey results showed that the increase in participants' understanding before the Technical Guidance on the material was in the range of the lowest 25% and the highest percentage of understanding was 50%. Then after the Technical Guidance was carried out, there was the highest increase in understanding in the material on pond preparation reaching 100% while the lowest was in the material on feed at 80%. The results of this service are important for the development of fisheries cultivation in general and increasing income for partner groups.

Animal waste management is an environmental challenge that can be turned into an economic opportunity through the right approach. This service program aims to assist the Pokdarwis Pilang community of Probolinggo City in managing animal waste into organic compost to support the sustainability of urban farming. The Asset-Based Community Development (ABCD) approach is used to empower the community by utilizing existing local assets, such as animal waste, community skills, and infrastructure support. The service process includes five stages: Discovery, Dream, Design, Define, and Destiny. The Discovery stage focused on identifying local assets, where animal waste was found to be a valuable asset that was previously not managed properly. Through the Dream stage, the community formulated a shared vision to create a sustainable waste treatment system. The Design stage implemented technical training and procurement of composting infrastructure. At the Define stage, the community began to manage the waste treatment independently, followed by an evaluation of the results and social impact at the Destiny stage. The results showed an increase in the technical skills of Pokdarwis members, the establishment of a compost production unit, and changes in community behavior in waste management. In addition, the formation of partnerships with local markets helped improve the economic welfare of the community. The ABCD approach has proven effective in creating sustainable social change through community empowerment. Recommendations from this program are to expand the application of the ABCD approach to other communities and strengthen collaboration with stakeholders to support the sustainability of waste management and urban farming.
