Abstract

Indonesia's tobacco has good potential for exporting to the world market. Cigars are one of the derivative products that can compete with other exporting countries in the world. The trend of Indonesian cigar exports in 2022 has decreased. The study aims to identify the relationship between Indonesian cigars and competing countries in the international market. The research data to be observed uses HS code 240210 by comparing competitor countries between Indonesia, the Dominican Republic, Belgium, Netherlands, Germany, Spain, and Hungary. The analysis method used is the AIDS (Almost Ideal Demand System) model, which will describe the price elasticity of demand, cross-price, and income. The results obtained are based on the income elasticity of Indonesian cigars, including normal goods, with a value of 0.0287. The cross-price elasticity results show that Indonesian cigars tend to compete with Netherlands, Belgium, Spain, and Hungary cigars because they are positive. Meanwhile, Indonesian cigars are related to the Dominican Republic and Germany as complementary goods. Based on the results of the price elasticity of demand, a negative value is obtained, including Indonesian cigars, which means that the demand for Indonesian cigars is inelastic.

Abstract

This study aims to assess the effectiveness of two different varieties of ornamental plants in remediating soil contaminated with cadmium and lead. The study was a two-cycle pot experiment with three replications arranged in a completely randomized design. The treatments include ornamental plants and contamination levels. Ornamental plants include Solenostemon scutellarioides (L.) Codd. var. Religious radish and Red-trailing-queen; Codiaeum variegatum L. var. Gold dust and Oakleaf. The concentrations were P0 (Pb at 0 mg.kg-1, Cd at 0 mg.kg-1), P1 (Pb at 1000 mg.kg-1, Cd at 2 mg.kg-1), P2 (Pb at 1500 mg.kg-1, Cd at 5 mg.kg-1), and P3 (Pb at 2000 mg.kg-1, Cd at 10 mg.kg-1). Dry matter weight (DMW), bioconcentration factor (BCF), and translocation factor (TF) were determined after harvest. The results showed that all plants’ DMW of shoot > DMW of root. Codiaeum variegatum varieties had BCF and TF of Cd higher than that of S. scutellarioides varieties. Similarly, S. scutellarioides varieties showed higher BCF and TF of Pb; however, there is a limit to how much Pb S. scutellarioides varieties may absorb from the soil, as BCF of Pb decreased after 1500 mg.kg‑1 lead contamination. The study found that the ornamental plants had high TF and low BCF values at high cadmium and lead levels, indicating their role as phytostabilizers. Among the plants studied, Oakleaf was identified as the most efficient phytostabilizer for cadmium, while Religious radish proved to be the most effective for lead.

Abstract

The declining number of farmers is a prominent problem in the agricultural sector. On the other hand, interest in engaging in agriculture, especially among the younger generation, has also declined. The younger generation tends to perceive working in agriculture as unprofitable. The young generation's intentions can be influenced by their perception and interest. This study aims to analyze the effect of young people's perceptions on interest and intention to work in the agricultural sector, analyze the effect of interest on intention and analyze the effect of perception on intention mediated by interest. The research was conducted in Jampet Village, Ngasem District, Bojonegoro Regency. A survey of 100 youths aged 15-35 in Jampet Village explored their perceptions and interests in agriculture through distributed questionnaires. Informants were determined using the purposive sampling method, and data were analyzed using the SEM method. In accordance with the test results, perception has a positive and significant influence on interest of 78.2% with a coefficient value of 0.782, and directly has a positive effect of 48.2% on the intention of the younger generation in business in agriculture; in addition, the interest variable also has a positive and significant influence of 46% on the intention of the younger generation to go directly into the agricultural sector. In comparison, the effect of perception on intention mediated by the interest variable shows positive and significant results of 35.9%.

Abstract

The research survey suggests that there are organic products that are often purchased by consumers such as vegetables, rice, seasonings, meat, tempe, milk, eggs, fruit, coffee, tofu and cooking oil. Vegetables are the most frequently purchased organic product at 23% (David & Ardiansyah, 2017). Consumer decisions in purchasing organic food products are influenced by the premium price and this is the main obstacle (Bryła, 2016). Research survey results show that 82% of consumers are unwilling to pay a premium price above 10-20% for organic food (Xie et al., 2015). The price range of organic products ranges from 6% to almost 300% higher than the price of inorganic products (Sörqvist et al., 2013). The price difference can affect consumers' willingness to pay. Based on this, it is necessary to research how much the value of willingness to pay is to be paid by people in the city of Bogor to pay for organic leaf vegetable products. The research was conducted in Bogor City and the location selection was done by purposive sampling. The independent variables studied were age, education, expenditure, gender, number of family members, marital status, health awareness and environmental awareness. The data source in this study uses primary data. Data collection time was conducted in April-June 2024. The number of samples used in this study were 200 respondents spread in five modern market places like all fresh, farmer market, yogya bogor junction, superindo and agrimart. The dependent variable is the amount of willingness to pay value of consumers' willingness to pay for organic leaf vegetable products. The stages of discrete choice experiment (DCE) analysis include (1) determining product attributes and levels; (2) constructing product profiles; (3) obtaining a discrete choice model (DCM); (4) analyzing DCM data sets using Stata software. Selection of DCE analysis to find the WTP value chosen by respondents as consumers of organic leaf vegetables with 3 physical attributes such as product type (organic or non-organic), label (there is or there is no label) and place (directly to modern markets or through online applications). The results showed that organic vegetable consumers are willing to pay more on attributes for organic products amounting to IDR 5,890.8; having / including labels of IDR 4,292.8; and IDR 2,992.45 on online purchases. Willingness to pay provides important insights for making strategic decisions in terms of pricing, production planning, and marketing of organic vegetable products. When knowing consumer WTP, marketers can set the optimal price according to consumer purchasing power and preferences. The right price can maximize sales as well as profit margins. In addition, by knowing the price limit that consumers are willing to pay, marketers can design attractive promotions without hurting their profitability. Producers can adjust the quality or type of product according to the preferences of consumers who want to buy organic vegetables.

Abstract

Mexican sunflower leaves (Tithonia diversifolia) contain high levels of nitrogen (N) and potassium (K). Combining it with poultry bone meal rich in phosphorus may produce a compost mix containing high N, P, and K. This research aims to compare the effect of this compost mix on the productivity and nutritional quality of Red Russian kale. The research was conducted at the Faculty of Agriculture and Business, Satya Wacana Christian University, from December 2023 to June 2024. Treatments tested were: CM-N100 (compost mix containing 100% of the required N); CM-P100 (compost mix containing 100% of the required P); CM-K100 (compost mix containing 100% of the required K); IF-NPK100 (inorganic fertilizer containing 100% of the required N, P, and K); and NPK0 (zero fertilization). Plant height, number of leaves, crown diameter, biomass, harvest index, vitamin C, total anthocyanins, total chlorophyll, and carotenoids were measured then analyzed using the ANOVA test and Tukey-test (P<0.05). CM-P100 and CM-K100 (180-200 g of compost mix per pot) resulted in the highest yield, vitamin C, chlorophyll, and carotenoids. However, both treatments resulted in the lowest anthocyanins content. CM-N100 (95 g of compost mix per pot) resulted in the highest anthocyanin accumulation (92.84 mg/100 g). IF-NPK100 has supplied Red Russian kale with adequate N, P, and K but resulted in lower yield and nutritional quality compared to CM-P100 and CM-K100. This indicated that higher nitrogen supply might still boost the productivity and nutritional content of Red Russian kale. Zero fertilization resulted in the least productive and nutritious kale leaves.

Abstract

Choosing the right seed size is essential in shallot cultivation. Using good-quality seeds will increase the growth of shallots. Through growth analysis of various sizes of shallot seedlings, information will be obtained about the growth potential of shallots. This research aims to compare the growth patterns of shallot seedlings of varying sizes. The research was carried out from August to September 2023 at Br. Aseman, Sedang Village, Abiansemal District, Badung Regency, Bali and at the Plant Breeding and Seed Technology Laboratory, Faculty of Agriculture, Udayana University, Denpasar. This research used a one-factor randomized block design (RBD) with different treatment sizes of shallot seedlings, namely 3 g, 5 g, 7 g, 9 g, and 11 g. Each treatment was repeated 5 times, yielding 25 experimental units. The results showed that differences in the size of shallot seedlings very significantly influenced the initial growth of the seedlings (3-15 DAP). The heavier the weight of the shallot seeds, the higher the growth of the shallots. The plant growth analysis metrics, relative growth rate and net assimilation rate, reveal that the results do not differ significantly across observation time intervals. The treatment using seed size 11 g showed the highest increase in each parameter compared to other treatments at each observation time interval.

Abstract

This study aimed to develop resistance in shallot (Allium cepa) against twisting disease caused by Fusarium oxysporum by applying microorganism-based biopesticides. By inducing resistance in shallots, the research sought to explore the pathogen-host interactions, understand infection mechanisms, and establish sustainable disease management strategies. Utilizing a biopesticide approach within an organic farming framework, this study aimed to assess the effectiveness of biopesticides in inducing plant defense mechanisms. The experimental design was non-factorial and followed a randomized block structure, consisting of four treatments with three replications each: (A) Chemical pesticide and fertilizer, (B) Biopesticide applied to seeds and plants, with chemical fertilizers on soil, (C) Soil sterilization with biopesticide and pesticide application on plants, and (D) Soil sterilization with biopesticide, with biopesticide applied to seeds and plants. Observations focused on disease intensity and salicylic and jasmonic acid levels in shallot bulbs. Results demonstrated that biopesticide application successfully reduced disease incidence and increased resistance, as shown by higher levels of salicylic and jasmonic acids in treated plants. The study concluded that biopesticides are promising for enhancing systemic resistance in shallots.

Abstract

Indonesia faces the challenge of declining agroecosystem quality due to the long-term use of synthetic chemical fertilizers, indicating the need for a transition to organic fertilizers to support sustainable agricultural practices. Therefore, this study aims to analyze the quality of liquid organic fertilizer made from dairy cow manure, laying hen manure, and Indigofera zollingeriana and to examine the effects of the combination of liquid organic fertilizer on the growth and yield of lettuce (Lactuca sativa L.). This research uses a Completely Randomized Design (CRD) experimental method with five treatments of liquid organic fertilizer (LOF) substitution and three replications to evaluate its effects on the growth and yield of hydroponic lettuce, where the data are analyzed using ANOVA and Tukey's post hoc test. The results show that the liquid organic fertilizer produced from the combination of dairy cow manure, laying hen manure, and Indigofera zollingeriana meets the quality standards of Minister of Agriculture Regulation No. 261 of 2019 with a total N content of 3.11%, P2O5 2.12%, and K2O 1.94%, and is effective in enhancing lettuce growth. The combination of liquid organic fertilizer and AB Mix, particularly AB Mix 75% + LOF 25% and AB Mix 50% + LOF 50%, results in optimal lettuce growth. Therefore, using a combination of liquid organic fertilizer and AB Mix can increase the efficiency of lettuce production in hydroponic systems and can be adopted by farmers to improve crop yields and quality.

Abstract

Chili is a horticultural commodity that has made significant contributions and has significant economic value in Indonesia. The prospect of increasing cayenne pepper production in Indonesia using simple linear regression analysis with chili production data from 1990-2022 has increased quite significantly. The attributes and results are added together to obtain the supply chain performance value based on performance attributes. These values are classified into standard performance values. The supply chain performance value based on attributes is 93.26 out of 100%. This value is obtained by adding up the values of each performance attribute. This value indicates that the performance of the Cayenne pepper supply chain in Indonesia is in the Good criteria (Above Average) based on the classification of standard work values. The SPSS output has an adjusted determination coefficient (Adjusted R Square) of 0.393. This means that 39.3% of the dependent variable (production (Y) is influenced by exports (X1) and imports (X2), while the remaining 60.7% (100% - 39.3) is influenced by other variables outside the variables used.
