Abstract

ENGLISHThe presence of the Tourism Awareness Group is a tangible manifestation of the tourism awareness movement. Some of local potential around the Maron River has not been utilized optimally. One of them is coconut fruit products which are quite abundant. The involvement of women in the development of Maron River tourism is also not optimal as the involvement of men. The purpose of the research is to increase the entrepreneurial interest of the Maron River Pokdarwis women with local potential. The type of research is experimental with a one-group pretest-posttest design. The research was carried out in August 2023. The research samples are 30 mothers from the Maron River’s Pokdarwis with an average age of 38.3 years (SD+11.92). Data collection using the Entrepreneurship Interest Scale (Rel=0.876) was carried out before and after training. Data analysis was done by descriptive quantitative and inferential statistics using the Wilcoxon Signed Rank Test technique. The results of the analysis showed that there was an increase in the average value of mothers' entrepreneurial interest after attending the training (pretest 98.9, posttest 103.2) with p=0.000 (p<0.05). In other words, training in utilizing local potential can increase the entrepreneurial interest of the women of Maron River’s Pokdarwis. INDONESIAKehadiran Kelompok Sadar Wisata (Pokdarwis) merupakan wujud nyata dari gerakan sadar wisata, yang bertujuan untuk meningkatkan kualitas program atraksi desa serta mendorong keterlibatan seluruh anggota masyarakat dalam upaya mendukung kemajuan pariwisata di desanya.

Abstract

According to information obtained from this community service activity, 80% people of Dersono Village work as farmers. The location of Dersono Village is within Gunungsewu Karst, which is known as a barren area. Therefore, it has been difficult for the villagers to get maximum harvests, which has impacted their economic standard of living. Being in the middle of the Karst area, Dersono Village has a potential that is the Maron River as it can be developed into a tourist attraction and become a source of the community's economy. In addition, Dersono Village has the potential with regard to their local commodities, namely coconuts, that can become superior products. The potential of this local coconut commodity can be developed as a superior processed product that can become a unique, distinctive souvenir and has more economic value rather than only selling the raw coconuts to collectors (intermediaries) or along the Maron River. To manage these existing potentials, adequate human resource skills are needed, one of which is through training in processing local products with economic value and activity in marketing processed local products. The training began with material delivery and continued with practices with the targeted community (PKK) to assess training achievement. A pre-test and post-test were administered on managing MSMEs, making and packaging coconut oil, and product marketing of blondo. The results were categorized on a scale of very low, low, medium, high, and very high understanding. The pre-test results showed 12.9% low, 48.4% medium, 35.5% high, and 3.2% very high. The post-test results showed significant differences, showing no low category, a decline in the moderate category to 16.1%, 61.3% for the high category, and 22.6% for the very high category. These results strongly suggest that there has been a significant improvement of the target community’s capacity after the training.

Abstract

An oxidation stability is very important for a long-term storage of biodiesel. Some physical (density and viscosity) and chemical properties (acid value, iodine value, and peroxide value) were analyzed to predict the oxidation stability for biodiesel produced from Waste Cooking Oil (WCO). WCO is one of the potential feedstocks in Indonesia, which is a large cooking oil consumer. Biodiesel from WCO was produced by transesterification process in 60 oC temperature for one hour reaction time. Methanol was added in 4:1 (v/v) ratio of WCO with 2% potassium hydroxide as a catalyst. This study observed the influence of tertiary butylhydroquinone (TBHQ), a synthetic antioxidant, on the oxidation stability of biodiesel. TBHQ was used as an antioxidant agent to prevent biodiesel oxidation for such long-term storage. It was blended with biodiesel at various concentrations (0-1200 ppm). Samples were taken every week to measure the density, viscosity, acid value, iodine value (IV) and peroxide value (PV) during the storage process of the biodiesel blends which was conducted for 4 weeks. The experimental results revealed that an improvement in oxidation stability was achieved in all TBHQ concentrations. All parameters meet Indonesia’s National Standards (SNI) for biodiesel added with TBHQ up to 1200 ppm. Biodiesel which was treated with 1200 ppm of TBHQ provided the best result, due to its density, viscosity, IV, and PV. However, TBHQ addition was did not affect the free fatty acid and acid number for 4 weeks of storage.

Abstract

Minyak biji nyamplung telah diproduksi di industri kecil maupun menengah dengan cara pengepresan bijinya. Minyak yang belum dimurnikan dijual sebagai bahan baku kosmetik untuk produk skin care dan obat tradisional seperti minyak urut maupun obat gatal. Namun, pengetahuan bahwa minyak ini dapat diolah lebih lanjut untuk produk farmasi belum diketahui pelaku usaha. Komponen utama minyak biji nyamplung berpotensi untuk diolah menjadi bahan bakar alternatif biodiesel sedangkan komponen minornya memiliki efek antibakteri terhadap Staphylococcus aureus dan Escheria coli. Minyak nyamplung juga merupakan sumber senyawa bioaktif. Salah satu konstituen utama dari biji nyamplung, calophyllolide, memiliki aktivitas anti-inflamasi, anti-koagulan, antibakteri dan antikanker. Mengingat manfaat minyak nyamplung yang beragam, maka perlu diberikan penyuluhan pada industri penghasil minyak nyamplung untuk mengembangkan produktivitasnya melalui diversifikasi pemanfaatan minyak nyamplung. Tujuan pengabdian pada masyarakat ini adalah memberikan wawasan kemanfaatan minyak nyamplung, sehingga UMKM yang bersangkutan dapat menghasilkan produk turunan lainnya selain dijual dalam bentuk unrefined oil. Kegiatan pengabdian pada masyarakat ini dilakukan di CV. Plantanesia. Pelatihan diberikan dalam bentuk sharing pengetahuan dan perkembangan teknologi terkini mengenai pemurnian minyak biji nyamplung serta ekstraksi komponen-komponen mayor dan minor. Penyampaian materi dilakukan melalui kunjungan ke lokasi dan penyuluhan secara daring pada pelaku usaha.

Abstract

The increasing environmental burden caused by plastic waste necessitates the exploration of sustainable alternatives such as starch-based biodegradable products. Sago starch, a renewable polysaccharide offers potential for such applications. However, its inherent limitations such as poor thermal stability and water resistance restrict its use in biodegradable product. This study investigates the effect of lintnerization, a mild acid hydrolysis process on the physicochemical properties of sago starch and evaluates its performance in biodegradable straw production. Sago starch was modified through a 120-hour lintnerization process using 2.2 N HCl, followed by washing and drying to obtain crystalline starch. The resulting starch was characterized by XRD and SEM, and its application in straws was assessed via yield, organoleptic tests, tensile strength, water resistance, and biodegradability. The yield of crystalline starch reached 99.89%, with organoleptic scores indicating good visual and textural quality. XRD analysis revealed an increase in crystallinity from 33.32% to 49.98%, while SEM confirmed significant granule degradation. Incorporating crystalline starch improved straw water resistance up to 83.65% and tensile strength up to 7.05 MPa fulfilling industry standards. However, the biodegradability test results were unreliable due to uncontrolled external factors. These findings demonstrate that lintnerization enhances starch performance for biodegradable applications.

Abstract

Unsaturated fatty acids are potential to be used for preventing degenerative diseases and developing brain function in babies. Separation of unsaturated fatty acids from saturated fatty acids efficiently achieved by urea complexation fractionation method. It is considered to be the simplest, most efficient, and lowest cost method. This study aimed to optimize urea complexation for increasing PUFA concentrations by determining solid-liquid equilibrium data of saturated fatty acids in short chain alcohols. In this study, there were two types of short chain alcohol, methanol and ethanol, in various concentrations (99,7%; 95%; 88%; 76% w/w) towards the solubility of saturated fatty acids, palmitic and stearic acid (PA and SA). PA and SA dissolved in various concentrations of methanol and ethanol to get homogeneous solutions. When solid SFA disappeared by heating the solution, or first formed by cooling the solution, the temperature was determined as the solid-liquid equilibrium temperature. The results showed that the best composition of solvent within high solubility level is ethanol 95% and methanol 99,7% over palmitic acid because it can dissolve at room temperature and below 0.01 mole fraction.Keywords:Alcohol, Fatty Acid, Solid-Liquid Equilibrium, Solubility

CV Plantanesia is a home industry that produces nyamplung (Calophyllum inophyllum) seed oil known as Tamanu oil. The oil is usually used for skin care products and traditional medicines such as wounds, skin diseases, rheumatism, massage oil and itching medicine. Tamanu oil production leaves solid waste from the pressing process, which is cake/seed dregs and shells/skin of nyamplung fruit. This waste is generated in large quantities and has not been utilized, so it is only disposed of as garbage or just burned. Nyamplung seed shells contain resin phenolic compounds which is used as antioxidant, anti-inflammatory, anti-cancer and anti-microbial properties. It can be used for medical treatment. This project aims to provide training on processing waste nyamplung seed oil, especially the seed shells and their processing to become resin. This activity is carried out at CV. Plantanesia which is located in Tasikmadu, Jaten, Karanganyar. The project was implemented in various activities, such as counseling, focus group discussions and workshop for extracting resin from nyamplung shells. The resin extraction and optimization process condition were developed at the Chemical Engineering Laboratory, Faculty of Engineering, Sebelas Maret University. The experimental results are implemented in the workshop at the industry. From this activity, partners gain increased insight into the use of nyamplung seed shells. The resin product is expected to be useful as a high value by-product to increase the benefit of the industry, as well as to overcome the waste problem.Keywords: nyamplung seed shell, resin, tamanu oil
