Abstract

Pudding is one of the processed foods made by mixing agar powder into water, milk, fruit pulp, to vegetable pulp which can produce a gel and has a soft texture. White dragon fruit is a type of fruit that is rarely used as pudding, because it has a less attractive color after being processed. In  this research, white dragon fruit pudding by adding purple sweet potato flour to increase the attractiveness of color, enrich the antioxidant activity, and increase the fiber content contained in the pudding to obtain a pudding of functional value. This study used a simple randomized design group (RAK), with a focus factor concentration of purple sweet potato flour consisting of 6 levels, including P0 (0% purple sweet potato flour), P1 (5% purple sweet potato flour), P2 (10% purple sweet potato flour), P3 (15% purple sweet potato flour), P4 (20% purple sweet potato flour), and P5 (25% purple sweet potato flour) with  4 times repetitions. The raw material analysis of purple sweet potato flour includes water content, ash content, fat content, fiber content, and antioxidant activity. Analysis of white dragon fruit pudding products includes analysis of water content, ash content, fat content, fiber content, antioxidant activity, color intensity, texture, and organoleptic test (texture, taste, aroma, color, and preference). The addition of purple sweet potato flour significantly affected the water content, ash content, antioxidant activity, color intensity, texture, and organoleptic test of white dragon fruit pudding. P1 formulation (5% purple sweet potato flour) was the best formulation with the water content of 76.41%, ash content of 0.28%, fat content of 3.56%, fiber content of 0.89%, antioxidant activity of 14.33%, brightness level of 39.35, redness level of 8.02, yellowish level of 3.92, and texture of 0.34 N.

Abstract

Motor and outboard boats are the main means by which fishersmen exploit the fisheries resources in these waters. The success of the catch and the efficiency of the fishermen's efforts are strongly influenced by various factors related to the characteristics of the boat, the fishing gear and the condition of the aquatic environment. This study aims to analyse the determinants of catch and catch per unit effort of motorboat and outboard motorboat fishers in bulukumba regency. Data collection techniques used were observation, interview and documentation. The number of samples was 81 modern fishermen (juragan fishermen) of motorboats out of 407 population using the Slovin formula method and 81 outboard motorboat fishermen out of 81 population using the area proportional random sampling method. Data analysis techniques used are statistical tests, classical assumptions tests using SPSS 25 and CPUE analysis. The study found that the length of fishing (X1), volume of diesel (X2), age of fishermen (X4), and fishing experience (X6) had a positive impact on the production of motorboat fishermen's catch (Y1) when examined independently. On the other hand, the number of labour (X3) and formal education of fishermen (X5) were negatively correlated with catch production. The duration of sea time (X7) and the power of the outboard engine (X8) have a positive impact, whereas the volume of petrol (X9), age of fishermen (X10), formal education of fishermen (X11), sea experience (X12), and number of fishing gear used (X13) have a negative impact on the catch rate of outboard motorboat fishermen (Y2). Based on the CPUE (Catch per Unit Effort) value, there has been a fluctuation of motorboat and outboard motorboat fishermen from 2017 to 2021. The average value per year, from 2017 to 2021, was 389.9914kg/trip for motorboat fishermen and 46.66028kg/trip for outboard motorboats. It is recommended to increase the number of fishing gear, particularly trawl gear, and transportation facilities in fishing. Fishers should be incentivised to utilise fishing equipment that is appropriate for the specific kind of fish and local aquatic environments in order to enhance catches and reduce negative impacts on fishing resources.

Abstract

At present, the level of public consumption of wheat flour is increasing but the production of wheat in Indonesia is very minimal so Indonesia still expects imports from several countries. Meanwhile, the use of low-fiber wheat flour can increase peoples consumption in excess, so it can increase excess calorie levels in the body which can trigger obesity. Therefore, it necessary to substitute local-based flour such as cassava flour to reduce wheat flour consumption and increase fiber content in the resulting product. This study aims to determine the effect of different concentrations of wheat flour and cassava flour and determine the right concentration on the chemical and organoleptic quality of steamed brownies as high fiber food. The research method used a a research design using a 1-factor Completely Randomized Design (CRD) with 4 treatments and 3 replications. Chemical quality analysis on steamed brownies, namely water content, crude fiber content, and calories. The organoleptic test is color, aroma, taste, and tenderness. The results showed that between different proportions of wheat flour and cassava flour had a significant effect on crude fiber content and very significant effect on calorie content. Based on the determination of all research parameters, it shows that formulation 3 with 60 grams wheat flour and 40 grams cassava flour is the best treatment with a result value (NH) 0.692 with parameter criteria in the form crude fiber content 22.9%, calorie content 6.74 cal, moisture content 19.04%, tenderness 3.68 (like), color 3.96 (like), taste 3.78 (like), and aroma 3.89 (like).

Abstract

This study aims to examine the effects of cinnamon (Cinnamomum burmannii) extraction temperature and duration on the physicochemical and organoleptic characteristics of herbal paper soap. The experiment involved three extraction temperatures (60°C, 70°C, and 80°C) and two extraction durations (15 and 20 minutes), resulting in six treatment combinations. The findings indicate that an extraction temperature of 60°C for 15 minutes produced the best moisture content, and foam stability, while the optimal free alkali content was obtained at 80°C for 20 minutes. The highest antibacterial activity was observed at 70°C for 15 minutes. In the organoleptic evaluation, the best color scoring was achieved at 60°C for 20 minutes, aroma scoring at 80°C for 20 minutes, and thickness scoring at 60°C for 15 minutes. Further analysis revealed that extraction temperature and duration significantly influenced the physicochemical properties, including free alkali content, foam stability, and skin irritation, as well as organoleptic characteristics such as color, aroma, and thickness. However, these factors had no significant effect on moisture content and antibacterial activity. Overall, the paper soap met the quality standards outlined in SNI 06-3532-2016, except for free alkali content, which exceeded the maximum allowable limit of 0.1%, making it non-compliant with soap quality standards

The treatments included lime concentrations of 1%, 2%, and 3%, with stirring times of 5 minutes and 10 minutes. The observed parameters included moisture content, fat content, free fatty acid levels, emulsion stability, spread ability, color, texture, aroma, and taste. Analysis of variance (ANOVA) results indicated that lime concentration and stirring time significantly influenced most margarine quality parameters. Increasing lime concentration and stirring time resulted in a rise in moisture content, ranging from 1.7249% to 3.1094%, and an increase in free fatty acid levels from 0.2543% to 0.4195%. Conversely, fat content decreased, ranging from 88.4387% to 81.3954%. Emulsion stability was within 99.6927%–99.8795%, while spread ability varied from 2.6335 g/mm² to 3.6473 g/mm². In terms of organoleptic properties, margarine color showed significant differences, with the highest value of 3.0000 (yellow) observed in the 3% lime concentration with a 5-minute stirring time, and the lowest value of 1.9524 (very yellow) found in the 2% lime concentration with a 10-minute stirring time. Margarine texture varied from firm to slightly firm, with the highest score of 2.6667 recorded for the 1% lime concentration with both 5- and 10-minute stirring times. Aroma intensity increased with higher lime concentrations, with the strongest aroma recorded at 2.9524 in the 3% lime treatment with a 5-minute stirring time. Meanwhile, taste remained mostly neutral, with the highest score of 3.3333 observed in the 2% lime concentration with a 10-minute stirring time. This study highlights that the appropriate combination of lime concentration and stirring time can produce margarine with improved quality characteristics
