Abstract

West Java is one of the provinces that has potential for mango cultivation because it has a climate that is suitable for this plant. However, in 2023 there will be a decline in mango production, followed by an increase in the level of mango consumption in Indonesia, which is indicated to be influenced by the way farmers cultivate mango plants. The aim of this research is to identify farmer characteristics and relate mango cultivation techniques to farmer income in two mango production centers in West Java, namely Majalengka and Cirebon. The research method used is descriptive statistics and non-parametric tests. Respondent selection used a two-stage stratified sampling technique. The sample for this research was 258 mango farmers in Majalengka and Cirebon. The research results show that the majority of mango farmers in Majalengka and Cirebon have a productive age range of 45 - 60 years with an elementary school education level and their main job is as mango farmers. Meanwhile, judging from the cultivation techniques, the majority of mango farmers in Majalengka and Cirebon plant mangoes in gardens/fields with the majority of farmers in Majalengka implementing a polyculture planting pattern, while Cirebon is more dominant in implementing a monoculture planting pattern with the gedong gincu variety as the main variety. Then, the majority of mango farmers in Majalengka and Cirebon have implemented off season technology in their mango cultivation activities. Mango farmers who have a risk-averse nature carry out harvesting independently and control pests. The majority of mango farmers use pesticides as a means of controlling pests. Then, there is a significant relationship between planting location, use of off season technology, and pest control and farmer income in Majalengka and Cirebon.Key-words: Mango cultivation techniques, farmer income, planting location, off season technology, pest control.

Abstract

activities. Such as, exercising, playing and relaxing. However, there is a problem that arises, namely a decrease in air quality due to emissions or exhaust gas from vehicles around the square. This is because the square is surrounded by the main road of Salatiga City. The aim of this research is to assess the ability of trees around the Alun-alun to absorb carbon and lead particles. The research method used was an exploration method where a total of 112 trees were analyzed for their ability to absorb carbon. Then trees that fall within a 5 meter radius around the road are samples for analysis of their ability to absorb lead, where the total number of trees sampled is 8 trees. Carbon absorption was assessed using the allometric equation while lead absorption used AAS (Atomatic Absorption Spectrophotometry). The average result of tree carbon uptake was 7,887 tonnes/ha, where the highest uptake was the Banyan tree at 70,267 tonnes/ha, the Angsana tree 20,046 tonnes/ha and the lowest was the Glodogan Tiang tree at 0.017 tonnes/ha. The lead uptake results showed that the Glodogan Tiang tree had the highest uptake of 590,500 ppm/g and the lowest was the Japanese Cedar tree at 65,100 ppm/g. The conclusion of this research shows that carbon uptake is influenced by trunk diameter and tree height, while lead uptake is influenced by tree location and leaf characteristics.

Abstract

Soybean (Glycine max L.) is a type of nutritious food crop because soybean seeds have high protein amino acid content. Increasing domestic production for soybean self-sufficiency needs to be done by expanding the planting area. The objective of this research is to examine the effect of ethyl methane sulfonate concentration and obtain soybean plants tolerant to drought and aluminum stress through in vitro selection. This research was conducted from November 2023 to January 2024 at the Tissue Culture Laboratory, Faculty of Agriculture, Andalas University. The research was arranged in a Completely Randomized Design consisting of 12 treatment levels of the combination of concentrations of abiotic selection agents PEG 4000 and AlCl3 induced by EMS mutation and 12 treatment levels of the combination of concentrations of abiotic selection agents PEG 4000 and AlCl3 not induced by EMS mutation with 3 replications. Data analysis was performed using independent sample t-test at a significance level of 5% and interpreted descriptively. The results showed that mutation induction using ethyl methane sulfonate (EMS) did not produce soybean somatic embryo mutants tolerant to drought and aluminum stress. Meanwhile, results from non-mutated callus produced somatic embryos suspected to be potential putative somaclonal candidates tolerant to drought and aluminum after double in vitro selection using 10% PEG 4000 and 150 ppm AlCl3 selection agents.

Abstract

Wine is a fermented drink made from grapes. In Indonesia, wine production is minimal, so this research explores non-grape raw materials for making wine, including wine made from Arabica coffee and Robusta coffee. This research aims to determine the characteristics of coffee wine from a combination of Arabica and Arabica coffee mixtures using the cold brew method using commercial yeast and the best composition between Arabica and Arabica coffee to produce quality coffee wine using the cold brew method. This research used a Completely Randomized Design (CRD) to compare the quality of wine which is a mixture of Arabica coffee (Coffea arabica) and Robusta coffee (Coffea canephora). The results of the research show that the characteristics of coffee wine mixed with Arabica and Robusta coffee using the cold brew method are a decrease in pH of around 4.23-4.30, a reduced sugar value between 16.82-17.80%, alcohol content in the range of 13.80-17.25%, caffeine content in the range 50.16 - 128.16 mg/100m, as well as treatment of 25% Arabica coffee composition with 75% Robusta produces coffee wine with the best characteristics, namely sugar content reduction (16.85%), pH (4.30), caffeine content (85.81 mg/100ml), and alcohol content (17.25%).

Abstract

The Cauliflower (Brassica oleraceae var botrytis L.) is a potential horticultural commodity that has great prospects for intensive development in the lowlands. The vitamin and fiber content in cauliflower is so abundant that it is very good for the human body. Cauliflowers can be cultivated on several types of mineral soil, one of which is acid sulfate mineral soil. Problems in acid sulfate mineral soils contain high clay, high soil acidity, a pyrite layer, and nutrient deficiencies. Efforts can be made to support the growth of cauliflower by applying a soil saturated culture system, providing combination of goat manure + bioboost + dolomite, and using lowland cauliflower varieties. The research location is at Golden River Camp Kalimas Village, Sungai Kakap District, Kubu Raya Regency. The research took place from July to November, 2023. The research design used was a Split Block Design, consisting of 2 treatment factors and repeated 3 times and consisting of 4 sample plants. The first factor is the variety as the main plot with 2 treatment levels (Larissa and Snow White) and the second factor is the combination of ts (goat manure ton/ha + bioboost ml/l + dolomite ton/ha) as a subplot with 4 treatment levels. The variables observed in this study consisted of the number of leaves (strands), leaf area (cm2), fresh weight of upper plants (g), dry weight of upper plants (g), age of flower appearance (hst), crop diameter (g) and crop weight (g). The results showed that there was a different response between the two varieties and the combination of goat manure + bioboost + dolomite on the growth and yield of cauliflower, The Larissa variety showed better growth and yield when compared to the Snow white variety and the combination of goat manure 10 tons/ha + bioboost 15 ml/l + dolomite 2 tons/ha can increase the growth and yield of cauliflower better than other ts combinations on tidal acid sulphate soil with soil  saturated culture system.

Abstract

Indonesia is one of the countries with the fourth highest rice consumption in the world. This large consumption must of course be supported by high rice production. Tasikmalaya Regency is not the area with the highest rice production in Indonesia, but this district has the potential for developing rice farming which can still be maximized. Based on this explanation, the research analyzes the factors that influence rice production in Tasikmalaya Regency using the multiple linear regression method with the help of SPSS and Microsoft Excel applications. Data was collected through a survey of 50 rice farmers in Tasikmalaya Regency using a questionnaire. The results of the analysis show that land area and fertilizer costs per season have a significant positive effect on rice production. Other factors such as farmer age, seed prices, farming experience, and dry grain prices do not partially have a significant influence on rice production. Furthermore, the regression model can be used to predict rice commodity production with 66% of the variance in Rice Production can be explained in this Regression model. Key-words: production, rice farming, regression analysis

Abstract

Plant performance, growth response, and chili production from curly chili varieties currently need to be improved and adapted to changes in the agroecosystem and agroclimate which are changing as a result of climate change. One of the methods that can be used is using gamma-ray irradiation. This research aims to determine the growth response of chili plants resulting from gamma irradiation and determine the plant genotypes that has the best growth from the Iggo and Thunder progenitors. The research used 107 genotypes resulting from gamma mutation with 3 control varieties, namely Iggo, Thunder, and Tavirus with an Augmented RKLT Design with eight replications. The results showed that the growth in height and diameter of plants in curly chilies resulting from gamma-ray irradiation aged 2-14 WAP followed a sigmoid curve. The lag phase occurs at 2-4 WAP, the log phase occurs at 4-8 WAP and the stationary phase occurs at 8-14 WAP. Giving high doses of gamma irradiation to Iggo and Thunder chili seeds resulted in slower plant growth compared to treatments without irradiation or low doses in terms of plant height and plant diameter. Genotypes that have good growth are IG-1 17, IG-2 107, IG-2 108, IG-3 129, and IG-3 241 for Iggo offspring and genotypes TH-1 365, TH-1 366, TH-2 482, TH-2 488, TH-4 339, TH-4 340, TH-4 338, TH-4 367, TH-4 336, and TH-6 482 for the Thunder offspring.

Abstract

Efforts to use the right cultivation system are one of the intensification programs. The right cultivation system does not only concern the use of superior varieties, but also the selection of the right planting system. The direct seed planting system and the transplanting system are alternative planting systems introduced to farmers to increase production. These two planting systems have differences in terms of technical aspects and also the use of production factors so that specific studies related to both need to be carried out in order to find the most appropriate, effective and efficient planting system in increasing production and farm income. The purpose of this study was to analyze the differences in income and to conduct a difference test on the income of the tabela and tapin systems in Pomontoro Village, Mataoleo District, Bombana Regency. The results showed that the income of the tabela and tapin systems had significant differences based on the results of the difference test using SPSS. Key-words: income, tabela, tapin

Abstract

Ethyl carbamate (EC) can be found in fermented products and alcoholic beverages. Tests on animals show this compound is a multisite carcinogen. The International Agency for Research on Cancer (IARC) classifies ethyl carbamate as a group 2A carcinogen. Due to its toxicity, ethyl carbamate in food products can be hazardous to health. Ethyl carbamate can be formed during fermentation and storage, which involves the reaction between ethanol and carbamyl compounds. The main precursor for the formation of ethyl carbamate is arginine metabolism by Saccharomyces cerevisiae and other lactic acid bacteria. Considering the toxicity of ethyl carbamate, it is crucial to understand the formation pathway, prominent analytical and monitoring techniques, mitigation practices and experimental methods to reduce EC. An effort can be conducted to mitigate EC by modifying bacterial genes for fermentation, which can be an applicable solution for the food industry.
