Abstract

This study aims to analyze fish consumption trends among Generation Z in Kendari, focusing on the social and economic factors that influence these trends. Generation Z, born between 1997 and 2012, shows diverse consumption preferences. Factors affecting fish consumption patterns in this group include frequency, motivation, preference for fish types, knowledge of fish benefits, as well as social, cultural, and economic influences such as fish prices. The study found that most respondents consume fish at least once a week, with a preference for marine fish over freshwater fish. Health benefits are the primary motivation for fish consumption, although knowledge about the health benefits of fish remains limited. The influence of family, peers, and social media plays a dominant role in shaping fish-eating habits. Additionally, the price of fish is a significant barrier in consumption decisionsamong Gen Z. These findings are expected to contribute to policies aimed at increasing the consumption of nutritious fish among the younger generation.

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

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

Rice as the main staple food in Indonesia has a relatively high glycemic index, which may increase the risk of metabolic disorders. Rice engineering through the retrogradation process is one approach that can be applied to reduce its glycemic index. This study aimed to evaluate the effectiveness of post-cooking freezing in engineering rice starch retrogradation to promote resistant starch formation and reduce glycemic digestibility. Freezing was conducted stepwise for 24, 48, and 72 hours. Retrogradation was analyzed through amylose absorbance measurement, while digestibility was evaluated by in vitro starch hydrolysis with glucose determination using a colorimetric method based on 3,5-dinitrosalicylic acid (DNS). The results showed that post-cooking freezing was able to reduce starch digestibility through the formation of retrograded structures. The hydrolysis index of all samples ranged from 2.79 to 4.60%, and the predicted glycemic index was in the range of 41.24–42.25, which falls into the low category. The pattern of digestibility changes showed an increasing trend at 24 and 48 hours of freezing, followed by a decrease at 72 hours. This digestibility profile formed a U-shaped pattern, which may be attributed to the dynamic nature of the retrogradation process during freezing. Keywords: functional rice, resistant starch, predicted glycemic index, starch hydrolysis, in vitro

Abstract

Green coconut (Cocos nucifera L.) is one of the tropical horticultural commodities widely consumed by Indonesian people and is empirically believed to have health benefits due to its vitamin C and antioxidant compounds. This study aims to analyze the levels of vitamin C and antioxidant activity in water and green coconut meat using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method. Vitamin C levels were determined using the iodimetric titration method, while antioxidant activity was measured based on the percentage inhibition of DPPH radicals at five concentration series (1,000-5,000 ppm) using a UV-Vis spectrophotometer, then expressed as an IC50 value through a linear regression equation. The results showed that the average vitamin C levels in coconut water were 29.35 ± 5.08 mg/100 g and in coconut meat were 28.48 ± 4.93 mg/100 g. The IC50 value of coconut water was 5,824.52 ppm and coconut meat was 5,423.78 ppm, both well above the 200 ppm threshold, so both samples were classified as having very weak antioxidant activity based on the DPPH test. Coconut meat showed a slightly lower IC50 than coconut water, but the difference was not substantial. The low levels of vitamin C in both parts of the green coconut fruit are suspected to be one of the main factors in the weak antioxidant activity detected. This study provides baseline data on the antioxidant potential of fresh green coconut without further extraction treatment, which can be a reference for future research on the processing or fortification of coconut-based food products.

Abstract

This study analyzes the proximate composition, vitamin C content, and antioxidant activity of the water and flesh of young green coconuts (Cocos nucifera L.). Coconut water contains 7.19–8.20% carbohydrates, 29.35 mg/100g vitamin C, and 0.068–0.163% protein. The flesh contains 5.56–6.44% fat, higher protein levels, an average moisture content of 87.50%, and 0.88% ash. Antioxidant activity increases linearly in the water and fluctuates in the flesh. The results highlight coconut water's potential as an antioxidant source and the nutritional value of the flesh for food and health applications.
