Abstract

Lowe's banana has the potential for high starch content. The processing of bananas into flour and starch offers more diverse development opportunities to achieve food security. The aim of this study was to determine the effect of soaking time in sodium metabisulphite and carboxy methyl cellulose solution on the chemical composition, starch content and gluten content of Lowe's banana flour. The design used was a completely randomised factorial design (CRD) with two factors: type of soaking agent (M) and soaking time (L). For each treatment, all contained 5 grams/litre of water with differences in the type of soaking agent, namely: water (M1), sodium metabisulphite (M2) and carboxymethyl cellulose (M3). As far as the soaking time is concerned, it consists of 3 treatments: (L1) = 6 hours; (L2) = 12 hours; and (L3) = 18 hours, so that there were 27 treatment units consisting of 3 x 3 different treatment combinations, which were then repeated three times. The research variables were proximate test, starch test and gluten test. The results showed that the longer the soaking time, the higher the water and protein content and the lower the ash, fat, carbohydrate, starch and gluten content. The best treatment was M1L3 which increased protein and decreased ash and gluten.

Abstract

Intercropping with legumes was reported to increase growth and yield components of cereal crops. To determine the effect of additive intercropping with peanut on growth and stem brix level of various varieties of sorghum (Sorghum bicolor L.), a pot experiment was carried out from September 2021 to January 2022 in plastic house, which were arranged according to a Completely Randomized Design consisting of two factors with three replications. The first factor was intercropping (T0: sorghum monocrop, T1: sorghum inserted with peanuts), and the second factor was sorghum varieties (V1: Latu Keta, V2: Gando Bura, V3: Gando Keta, V4: Samurai-2). Data were analyzed with analysis of variance (ANOVA) and Tukey's HSD at 5% significance level using Costat for Windows ver. 6.303. The results showed that intercropping only significantly increased plant height (42 and 56 DAP), number of leaves (42 and 56 DAP), and growth rate of leaf number, when compared with monocrop sorghum, whereas differences in varieties affected almost all observed variables, except number of leaves 28 DAP. However, there was an interaction effect of the treatment factors (T*V) on plant height at 56 DAP, growth rate of plant height, and number of leaves at 42 DAP. Intercropping significantly increased plant height and leaf number in Gando Bura and Gando Keta varieties, but the increase in stem brix content due to intercropping was significant only in Gando Bura variety. Further research in the field is needed for better results from the real farms.

Abstract

Mineral soil has a high bulk density and is a limiting factor as a nursery medium. For the application of nursery media, planting media that is light, large water holding capacity are also needed. The magot compost comes from the Magot Lingsar unit the Regional TPA of NTB Province and the soil contains pumice an average of 68.2% comes from Tanak Beak Village, Central Lombok Regency, which has potential as a medium for nurseries. The purpose of this study was to identify the Bulk Density and water holding capacity of magot compost and soil containing pumice with the control variable of mineral soil from Labuapi, West Lombok Regency. Bulk density analysis method by analyzing dry weight per unit volume on soil rings and water capacity by analyzing wet weight minus dry weight. The subjects studied were magot compost with size < 2 mm, soil containing pumice size < 2 mm and control soil mineral rice fields. The results showed that the lowest Bulk Density was magot compost 0.42 gr/cm3, soil containing soil 0,64 gr/cm3, and rice field soil 1.42 gr/cm3, this was because magot compost was residue from waste. While the largest water holding capacity was soil containing pumice of 42.67%, magot compost 22.00%, and paddy soil 6.33%, caused by the number of macro and micro pores in pumice, whereas in magot compost water is bound to the humus surface. Suggestions for further research are the permanent wilting point time test on plant seeds.

Abstract

Rice is a strategic food commodity that needs to be maintained for production stability. This can be done by testing various aspects of both productivity and resistance to pests and diseases.  West Sumatra has genetic resources of paddy rice that can be developed into superior varieties.  Rice paddy genotypes that have been released into varieties such as Batang Anai, Anak Daro, Bakwan, and Marapulai.  But there are also many that have not been made into varieties, including Bujang Marantau, Kuriak Kusuik, Kuriak Putiah, which are still cultivated by farmers. Therefore, testing the adaptability of local paddy rice genotypes is one of the initial strategies.  The experiment was conducted on paddy fields in 2 (two) locations, Tolatang Kamang and Ampek Angkek Agam Regency, West Sumatra Province. The experiment was conducted from February to June 2022.   The experiment used a Randomised Block Design with 3 blocks. Treatments consisted of 5 (five) phenotypes including; Kusuik Putiah, Kuriak Kusuik, Kuriak Putiah, Ampek Bulan Putiah, and Cantik Manis.  Variables observed in the field during plant growth from the vegetative, generative phase to harvest include; plant height, number of productive tillers per clump, panicle length, flowering age, number of grains per panicle, number of full grains per panicle, harvest age, weight of 1,000 grains, dry grain weight per ha, resistance to brown stem leafhopper, and bacterial leaf blight. Observational data were analyzed statistically using the STATISTIX ver 8.0 program.  Brown planthopper pest attack was observed by referring to the criteria set by IRRI.  The results of the study can be concluded, Kusuik Putih is one of the local paddy rice genotypes from West Sumatra that can be proposed as a candidate for new superior varieties with dry grain weight reaching 6.95 t per ha, but, bacterial leaf blight resistance is still classified as susceptible to moderately vulnerable, followed by other local rice such as Kuriak Putiah (5.92 t.ha 1), Cantik Manis (5.55 t.ha 1), Ampek Bulan Putiah (5.30 t.ha 1), and Kuriak Kusuik (4.95 t.ha 1), which are moderately resistant to brown stem leafhopper and bacterial leaf blight.

Abstract

Porang is a tuber which is abundantly in Indonesia, especially in the East Kalimantan region. However, the potential of porang tubers is still not widely known and optimally developed, particularly in product diversification. The stages in this research consist of making porang’s chips, making porang’s flour, physicochemical analysis of porang’s flour. Based on the research results, the yield of porang chips was 19.12% and porang flour was 23.5%. The color of the flour produced is bright yellow, due to the carotenoid content in porang tubers. The proximate content of flour is dominated by the highest nutritional content in protein content (12.34%), while other proximate contents are as follows water content (12.29%), ash content (7.85%), fat content (1.54%), and carbohydrate content (65.98%) . The high protein and low fat content produced in the research shows the potential for East Kalimantan porang flour to be developed into a functional ingredient which is beneficial for health.
