Abstract

In line with the increase number of populations, the shallot demand is also increase. Thus, some efforts are needed to increase the shallot production on the degraded agricultural land, especially on ultisol. This study aimed to (1) identify the best dose of organic matter and mycorrhiza and the interactions between these two treatments in increasing shallot production on ultisol, (2) analyze the improvement of chemical properties of ultisols using mycorrhiza and organic fertilizer, and (3) measure the increase of vegetative and generatif (production) growth of shallot using these treatments. The study was designed by factorial randomized block design  with some levels. Treatment 1 (Mycorrhiza), M0 = Control, M1 = 10 g/polybag, M2 = 20 g/polybag, M3 = 30 g/polybag, M4 = 40 g/polybag, and Treatment 2 (Organic Fertilizer), P0 = Control, P1 = organic fertilizer (0.6 kg/polybag), P2 = organic fertilizer (1.2 kg/polybag), P3 = organic fertilizer (1.8 kg/polybag), P4 = organic fertilizer (2.4 kg/polybag). The results show that the mycorrhiza treatment just give the significant effect on the paramters of the wet and dry shallot weights. The highest result was found in the M4 treatment (13,9 dan 1,79 gr) and the lowest in the M0 treatment (7,89 dan 0,86 gr) for the wet and dry shallot weigths respectively. The organic fertlizer gives significant effects on all parameters, for the highest output was found in the P3 (30,24 cm, 38,47 leaves, 12,75 gr dan 1,58 gr) dan the lowest from P0 (12,58 cm, 9,57 leaves, 5,46 gr dan 0,86 gr) for the parameters of the height, number of leaves, wet weight and dry weight, respectively. The interaction between two paramters did not give the significant effect on the wet and dry weights. Fortunately, the interaction of the M4P4 treatment give significant effect on the height parameter (37,17 cm) and the M1P3 treatment give significant effect on the parameter of the number of leaves (46 number of leaves).

Abstract

This study aims to determine the level of behavior of organic rice farmers in carrying out environmentally friendly rice cultivation, the relationship between farmer group support and other factors related to the behavior of organic rice farmers in carrying out environmentally friendly rice cultivation in Purwo Kencono Village, East Lampung. This research was conducted in Purwo Kencono Village, Sekampung Udik District, East Lampung Regency in October 2022. The respondents in this study were members of the Multi Baliwo farmer group with 30 people in total This study uses the census method with a descriptive-quantitative approach using data testing using non-parametric statistics using Spearman's Rank correlation test. The results showed that the behavior level of organic rice farmers was in the medium category. In this study, there are four factors that influence the behavior of farmers, namely: age, education level, and length of farming, but the results of the Spearman Rank correlation test show that only farmer group support is related to the behavior of organic rice farmers in carrying out environmentally friendly rice cultivation with a significance value of 0.487. ** which means the correlation strength is quite strong. Farmer groups have tried to maximize their role for organic rice farmers, especially in improving the behavior of organic rice farmers in carrying out environmentally friendly rice cultivation

Abstract

The aim of the study was to obtain second generation mutant lines (M2) from three gene-mutated soybean seeds, namely M2 Anjasmoro, M2 Argomulyo and M2 Dena-1 which are tolerant to drought stress, water saturation stress and high yield potential. The research was carried out in the Maros district, South Sulawesi, July-November 2022, arranged in a split plot design. The main plot is the application of water consisting of three levels, namely selection of drought stress (C1), selection of water saturation stress (C2) and selection of optimum conditions (C3). Subplots are three second generation soybean seeds resulting from gene mutations (M2), namely: M2 Anjasmoro, M2 Argomulyo and M2 Dena-1. The results showed that the best plant agronomic characters for growth and production factors were M2 Anjasmoro for water saturation stress treatment and M2 Argomulyo and M2 Dena-1 for drought stress treatment. The fastest harvesting age was obtained from the combination of drought stress and M2 Argomulyo, namely 79 days and not significantly different from the combination of drought stress and M2 Dena-1, namely 79.34 days, but significantly different from the other treatment combinations. The production obtained from the seeds resulting from the second generation of gene mutations has begun to show a difference between those given the mutation treatment and their parents, where the combination of water saturation stress and M2 Anjasmoro gave the highest production of 3.20 tonnes/ha higher than the production of its parents which only reached 2. .03-2.25 tonnes/ha. Generation M2 Argomulyo seeds were the longest surviving seeds to recovery from drought stress (38 days), in the sense that M2 Argomulyo seeds were more resistant to drought stress than the other two generations of seeds, namely M2 Anjasmoro (36 days) and M2 Dena-1 (37 days). Meanwhile, the resistance to water saturation was shown by M2 Dena-1 generation seeds, namely 40.67 days, followed by M2 Argomulyo 29.67 days and M2 Anjasmoro 27.33 days.

Abstract

Cililin is one of the robusta coffee producing regions in Indonesia, but there are still many people who do not know robusta coffee from Cililin, so an effort is needed to improve its quality. Coffee that goes through heating stages such as drying or roasting will cause several other chemical ingredients to change. Coffee processing can affect the characteristics and taste of the coffee produced. Soaking with sorbitol solution can retain moisture (humectant) in food and in processing that undergoes high temperature treatment so that it will not cause browning reactions One of the stages carried out in coffee processing using high temperatures is the roasting process. Therefore, a study was conducted to determine the effect of the difference in sorbitol concentration with roasting level on the characteristics of the Cililin robusta coffee products produced. This study consisted of two factors, namely sorbitol concentration (a1=10%, a2=15%, a3=20%) and roasting rate (b1 = Light Roast, b2 = Medium Roast, b3 = Dark Roast).Data processing using Two Way Anova on SPSS application version 26.0. The results showed that concentration had an effect on water content, color test and organoleptic response in color, aroma, and texture attributes, but did not affect the characteristics of caffeine levels, and pH. Roasting rate affects coffee characteristics, namely moisture content, caffeine content, pH, color test, and organoleptic response in color, aroma, and texture attributes. The interaction between sorbitol concentration and roasting rate affects the characteristics of robusta cililin coffee, namely moisture content and color test. However, it has no effect on the characteristics of caffeine levels, and pH.

Abstract

Sorghum (Sorghum bicolor L. Moench) is an alternative food commodity with significant potential for development in Indonesia. However, its genetic diversity in Indonesia is relatively low. The low genetic diversity of sorghum prompts efforts to improve and search for new sources of genetic diversity, including through plant breeding. Radiation-induced mutation is a plant breeding technique aimed at obtaining new traits that are not present in the parent plants. Gamma ray irradiation can damage DNA, and during the repair process, DNA undergoes new mutations induced randomly. This study aims to investigate the agronomic characteristics, genetic diversity, and relationship among plants that have been irradiated with gamma rays using the Random Amplified Polymorphic DNA (RAPD) molecular markers. In this study, local sorghum varieties from Bandung, Demak, and Jember  were subjected to gamma ray irradiation at doses of 0 Gy, 300 Gy, and 500 Gy to induce genetic diversity. The application of gamma ray irradiation doses had a significant impact on parameters such as viability, vigor, and morphology. The isolated DNA was analyzed using the Random Amplified Polymorphic DNA technique. OPA-12 showed the highest level of polymorphism among the four primers used. The bands produced by the four scored primers were analyzed using the NTSYSpc program to determine the level of relatedness between genotypes. The genetic distance between genotypes was considerably wide, ranging from 0.1 to 0.46, indicating the potential for crossbreeding

Abstract

Cooperatives can potentially have a broad impact on the economic order. The success of cooperatives can benefit members, the surrounding environment, and even the broader scope. The agricultural sector is the third largest number of cooperatives in Lampung Province. This research aimed to analyze the factors that affect cooperative business volume, and net income (SHU) of agricultural sector cooperatives in Lampung Province. The number of samples in this study was 33 cooperatives. The samples are cooperatives that run agricultural related businesses and cooperatives whose members are agricultural business actors in Lampung Province. The multiple linear regression was used to analyze factors that influenced the business volume and the net income (SHU). It was found the number of members and business units have a negative effect on business volume, while capital and loan capital have a positive effect on business volume. At the same time, the variables of managers' availability and the chairman's education level do not affect the business volume of agricultural sector cooperatives in Lampung Province. Self-capital, loan capital, and the chairman's high level of education have a positive effect on business rest, and the number of members and business units have a negative effect on the net income (SHU). In contrast, the manager availability and the chairman’s education level at imtermediate and low levels have no effect on the net income (SHU) of agricultural sector cooperatives in Lampung Province. Keywords: agricultural cooperatives, business volume, net income (SHU)
