Dhaifillah Khoshy, Agus Suyanto, Ismail Astar — Mon, 14 Apr 2025 00:00:00 +0700

This research aims to determine the effect of adding CMC to the quality of Pontianak siamese orange fruit leather. The innovation in making Pontianak Siamese orange fruit leather is an effort to process Siamese oranges to extend shelf life and increase their selling price. This research was used a single factor completely randomized design method with six treatments and four replications. The treatment of the concentrations of CMC are 0% w/w; 0.1% w/w; 0.3% w/w; 0.5% w/w; 0.7% w/w and 0.9% w/w for 100 g of total material. All samples of Pontianak siam orange fruit leather were analyzed physically, namely textural analysis (hardness) and chemical analysis, namely proximate analysis including moisture, ash, and vitamin C content, as well as organoleptic tests using the hedonic preference test method. The results showed that the average hardness test (texture analyzer) was 0.19 kgf, the moisture content was 7.31%, the ash content was 1.49%, and the vitamin C content was 0.16%. The influence of adding CMC could be knowm by analyzed it with SPSS 16 with One Way Anova 0,05 and for acceptance were used hedonic rank, if there are some differences, Duncan were used. The result of One Way Anova were showed that was significant on increasing water content, ash content, and vitamin C content. However, this did not significantly affect of hardness of fruit leather. The addition of CMC also has an effect on the organoleptic characteristics of the taste attributes. However, it did not significantly affect texture, color, aroma, and overall attributes. The results of the organoleptic test showed that the 0.7% CMC treatment as a whole had a high percentage of each assessment attribute. Meanwhile, based on the physical and chemical characteristics, the best formulation was the 0.3% CMC treatment because it had the highest vitamin C content of 0.22% and a good hardness of 0.23 kgf and a moisture content of 7.00% and a low ash content. of 1.31%.

The purpose of the research, which was carried out in December 2023–January 2024 at the Ngabang People’s Traditional Market, Ngabang District, Landak Regency, is to assess and ascertain consumer attitudes on the purchase of fresh long bean vegetables at the market. Using an incidental sampling strategy, the research was able to obtain 50 respondents who satisfied the research's criteria. The respondents in this study were consumers who were purchasing long bean vegetables. The collected data is processed, assembled, examined, and concluded using the descriptive analysis data analysis method. The three variables in this study are the conative, emotional, and cognitive aspects of evaluative attitudes. All three have the same indicators, which are price, vegetal texture, cleanliness, brightness, and freshness. Following collection, the aforementioned data was examined using a Likert scale. According to the research findings, nearly all respondents had favorable opinions about purchasing fresh long bean vegetables when asked the questions that were included in the consumer attitude analysis

Pengaruh Biochar Sekam Padi dan POC NASA Terhadap Pertumbuhan Dan Hasil Tanaman Lobak Merah (Raphanus sativus L.) Pada Tanah Alluvial di Polybag

Rahayu Ningsih, Sri Andayani, Setiawan — Mon, 14 Apr 2025 00:00:00 +0700

This study aims to determine the effect of the interaction of rice husk biochar and NASA POC on the growth and yield of red radish (Raphanus sativus L.) on alluvial soil in polybags. This research was conducted at Our Lady of Jeruju Parish, Jalan KomYos Soedarso, Kec. West Pontianak, Pontianak City, West Kalimantan. The method used in this study was a completely randomized design (CRD) consisting of two factors. The first factor is Biochar rice husk with code (B) of 3 levels, namely: b1=20 gram/polybag, b2= 40 gram/polybag, b3=60 gram/polybag. The second factor is NASA Liquid Organic Fertilizer with code (N) in 3 levels with concentrations: n1 = 2ml/liter of water, n2= 4ml/liter of water, n3= 6ml/liter of water. Each treatment was repeated 3 times and each repetition consisted of 3 plants. The results showed that there was an interaction between rice husk biochar and NASA POC which had a very significant effect on plant height, tuber weight and had a significant effect on tuber diameter. However, it had no significant effect on the number of leaves and tuber length of red radish plants. The highest yield for the average plant height was found in b3n3 (60 gram rice husk biochar/polybag & NASA POC 6ml/liter of water), namely 36.83 cm. The highest yield on the average number of leaves was found in b2n1 (40 gram rice husk biochar/polybag & NASA POC 2ml/liter of water), namely 19.89 strands. The highest yield on the average tuber length was found in b1n2 (20 gram rice husk biochar/polybag & 4ml/liter of water) which was 14.27 cm. the highest yield on average tuber diameter was found in b1n3 (20 gram rice husk biochar/polybag & NASA POC 6ml/liter of water) which was 5.17 cm and the highest yield on average tuber weight was found in b1n3 (20 gram rice husk biochar /polybag & 6ml/liter of water) which is 177.00 grams

This research aims to obtain location-specific Trichoderma sp. that can be utilized as a biological control agent. The research was conducted in Bulu Bala Village, Balai District, Sanggau Regency, and continued at the Laboratory of the Faculty of Agriculture, Science, and Technology, Jl. Komodor Yos Sudarso No.1, Sungai Beliung, Pontianak Barat District, Pontianak City, West Kalimantan. This research lasted for 6 months, from September 2023 to March 2024. This research used the baiting method as a trap for Trichoderma sp. fungi. Exploration was carried out in rubber and oil palm plantations. From the exploration and identification results, 2 fungal isolates were found, namely Trichoderma sp. Rubber Isolate and Trichoderma sp. Oil Palm Isolate. The conidium density calculation results for Trichoderma sp. Rubber Isolate was (1.53 x 10^9) conidia/ml and Trichoderma sp. Oil Palm Isolate was (1.48 x 10^9) conidia/ml. The conidium viability of Trichoderma sp. Rubber Isolate was 89.70% and Trichoderma sp. Oil Palm Isolate was 78.34%. The inhibition test results against Ganoderma sp. showed that Trichoderma sp. Rubber Isolate on the fourteenth day had an inhibition rate of 66.76%, while Trichoderma sp. Oil Palm Isolate had an inhibition rate of 73.33%.

This study aims to determine the effect of different media types on the growth of the fungus Trichoderma sp. The research was conducted at the Laboratory of the Faculty of Agriculture, Science, and Technology, Jl. Komodor Yos Sudarso No. 1, Sungai Beliung, West Pontianak District, Pontianak City, West Kalimantan. The study lasted for two months, from February 2024 to April 2024.This research employed a Completely Randomized Design (CRD) with a single factor, which was the type of media (code T), consisting of 8 treatments. The treatments were as follows: t1: Rice, t2: Corn, t3: Sugarcane Bagasse, t4: Bran, t5: Rice + Bran (1:1), t6: Corn + Bran (1:1), t7: Rice + Sugarcane Bagasse (1:1), and t8: Corn + Sugarcane Bagasse (1:1). Each treatment was repeated three times, resulting in a total of 24 experimental units. The observed variables in this study were the conidium density and viability of the Trichoderma sp. conidia. To determine the effect of the treatments on the observed variables, variance analysis (ANOVA) was performed using an F-test at a significance level of 5% and 1%. If there was a significant or highly significant effect from the treatments, it was followed by an Honest Significant Difference (HSD) test at a 5% significance level.The results of the study showed that the type of media had a highly significant effect on the conidium density and viability of the Trichoderma sp. The highest conidium density was found in treatment t8 (Corn + Sugarcane Bagasse), which was 3.27x10^9 conidia/ml, significantly different from treatments t1 (Rice), t7 (Rice + Sugarcane Bagasse), and t3 (Sugarcane Bagasse), but not significantly different from treatments t2 (Corn), t4 (Bran), t5 (Rice + Bran), and t6 (Corn + Bran). The highest spore viability of 96.8% was found in treatment t2 (Corn), significantly different from treatments t1 (Rice), t7 (Rice + Sugarcane Bagasse), t6 (Corn + Bran), and t5 (Rice + Bran), and not significantly different from treatments t4 (Bran), t8 (Corn + Sugarcane Bagasse), and t3 (Sugarcane Bagasse)
