Abstract

Tujuan penelitian ini adalah 1) Menentukan pengaruh lama pemanasan melalui pemanasan terhadap karaketertik kimia minuman fermentasi kopi wine arabika (Kadar Alkohol, Total Padatan Terlarut dan Total Asam. 2) Menentukan lama pemanasan terbaik untuk mendapatkan produk minuman kopi wine rendah alkohol dengan varian rasa baru dan layak untuk dikonsumsi. Metode penelitian ini menggunakan Rancangan Acak Lengkap (RAL) non faktorial yang terdiri dari 4 taraf perlakuan dan masing-masing perlakuan diulang sebanyak tiga kali, adapun perlakuanya sebagai berikut; P0= kontrol (tanpa pemanasan), P1= Lama pemanasan 15 menit, P2= Lama pemanasan 25 menit dan P3= Lama pemanasan 35 menit. Data karakteristik kimia yang diperoleh diolah menggunakan analisis keragaman ANOVA. Kriteria berbeda nyata yang digunakan pada penelitian ini adalah pada tingkat kepercayaan 95% (p<0,05). Analisis statistik dilakukan dengan menggunakan bantuan sofware SPSS 25. Hasil penelitian yang diperoleh menunjukan bahwa lama waktu pemanasan minuman fermentasi kopi cherry arabika berpengaruh nyata (p<0.05) terhadap kadar alkohol, total padatan terlarut dan total asam. Semakin lama waktu pemanasan maka dapat menurunkan kandungan kadar alkohol dan total asam serta meningkatkan nilai total padatan terlarut minuman fermentasi kopi cherry arabika.

Abstract

Yellow coconut (Cocos nucifera L) is an underexplored variety with significant potential in the agricultural and food sectors. Unlike regular coconuts, yellow coconuts have a distinct yellow skin and sweeter water. This study evaluates the antioxidant activity of yellow coconut water and flesh using the DPPH (2,2-Diphenyl-1-Picrylhydrazyl) method, which measures the ability to neutralize free radicals. Results indicate that both yellow coconut water and flesh contain bioactive compounds with notable antioxidant properties, though their activities vary depending on concentration. The water showed significant antioxidant activity at higher concentrations, whereas the flesh showed better activity at lower concentrations. The IC50 values for yellow coconut water and flesh were 900.6 ppm and 1342 ppm, respectively, showing that while both parts have promising antioxidant potential, higher concentrations are needed for more effective results. This research provides valuable insights into the potential of yellow coconut as a natural antioxidant source and its implications for food and health product development.

Abstract

This study aims to analyze the nutritional composition and antioxidant activity of yellow coconut (Cocosnucifera), focusing on both the flesh and water parts. The analyzed parameters include vitamin C, protein, carbohydrate, fat, moisture, ash content, and antioxidant activity using the DPPH method. The results showed that yellow coconut flesh contains more nutrients than its water, with a vitamin C content of 237.67 mg/100g, protein at 1566 ppm, and fat at 93.67%. Moisture and ash contents were 91.33% and 0.82%, respectively. These findings suggest that yellow coconut, particularly its flesh, has significant potential as a functional food to support health and warrants further development in the natural food industry
TRAINING AND COMMUNITY MENTORING ON THE PRODUCTION OF VIRGIN COCONUT OIL (VCO) AND NATA DE COCO IN PADALEU SUBDISTRICT, KENDARI CITY: PELATIHAN DAN PENDAMPINGAN MASYARAKAT DALAM PEMBUATAN VIRGIN COCONUT OIL (VCO) DAN NATA DE COCO DI KELURAHAN PADALEU KOTA KENDARI Baihaqi; Sakir; Fatahu; Windayani; Ika Rezvani Aprita; Sri Agustina

Abstract

Padaleu Subdistrict, Kendari City, has significant potential for coconut resources, yet its utilization remains limited to low-value-added products. This community service activity aims to enhance the local community’s knowledge and skills through training and mentoring in producing Virgin Coconut Oil (VCO) and nata de coco as value-added coconut products with economic potential. The implementation method includes preparation, training through lectures and hands-on practice, production mentoring, and evaluation using pretest-posttest, skill assessments, and production outcomes. The results show an increase in participants’ knowledge, with an average pretest score of 52.44 rising to 72.88 in the posttest. Participants’ skills also improved, with the average score increasing from 2.15 to 3.31 on a 1–4 scale. The production success rate for VCO was 84%, while for nata de coco it was 56%, with a contamination rate of 20%. The difference in success rates indicates that VCO technology is easier to adopt than nata de coco, which requires stricter sanitation controls and fermentation processes. The activity is considered effective in enhancing the community’s capacity for coconut processing, given its local potential. Further mentoring is needed to improve product quality consistency, especially nata de coco, to ensure its sustainability and competitiveness as a household-based business.

Abstract

Kabuto is a traditional fermented food originating from Muna Regency, Southeast Sulawesi, Indonesia, made from cassava through a spontaneous fermentation process. The presence of microorganisms during fermentation plays an important role in the development of sensory characteristics such as flavor, aroma, texture, and ultimately determines the final quality of the product. This study aimed to isolate and identify microorganisms involved in the fermentation process of kabuto. Microbial isolation was conducted on days 0, 2, 4, and 6 of fermentation using the pour plate and spread plate methods on de Man, Rogosa and Sharpe Agar (MRSA), followed by incubation at 37 °C for 48 hours. The resulting colonies were enumerated using the Total Plate Count (TPC) method, and Gram staining was performed to determine the characteristics of bacteria present during fermentation. The results showed that the microbial population increased gradually throughout the fermentation process, reaching the highest count on day 6 at 1.68 × 10^8 CFU/g. Gram staining results indicated that the microbial population was dominated by Gram-positive bacteria, suggesting the presence of lactic acid bacteria as the primary microorganisms involved in fermentation. Gram-negative bacteria were detected at the early stage, likely originating from raw materials and the surrounding environment. The dominance of lactic acid bacteria has positive implications for product safety due to pH reduction and inhibition of pathogenic microorganisms. However, the presence of Gram-negative bacteria in the early stage indicates a potential risk of contamination if proper sanitation is not maintained. Therefore, process control and hygienic practices are essential to ensure the safety of kabuto. Further studies are recommended to perform molecular identification and evaluate food safety parameters. Keywords: lactic acid bacteria, fermentation, Kabuto
