Abstract

Coconut is one of the key plantation commodities in the Mempawah Regency that needs to be developed. This is necessary in order to increase the income of coconut sugar craftsmen and also allow them gain knowledge of the industrial scale through feasibility studies on the agro-industry. Therefore, this study aims to analyze the structure of production cost and operating income as well as the feasibility of the coconut sugar agro-industry. This analysis is important for craftsmen in the regency that engage in the continuous production of coconut sugar. Furthermore, this study was conducted in Mempawah Regency with 34 coconut farmers. The analysis of the R/C ratio and Break-Even Point (BEP) was used to determine the indicator of financial feasibility. The result revealed that the average production cost needed by the agro-industry was 7,659,868 IDR month-1 and the generated income was 3,483,132 IDR month-1. Additionally, the coconut sugar agro-industry was financially feasible as the obtained R/C ratio was 1.45. The BEP of production volume and Cost of Good Solds (COGS) was 346 kg and 9,814.92 IDR which is less than the actual production volume and price. It was suggested that craftsmen of coconut sugar produce more than 346 kg of sugar per month with a selling price above 9,814.92 IDR kg-1 in order to obtain profit.

Abstract

The local onion market in Ghana is dominated by ‘on the spot’ market relationships with little or no coordination of chains to improve quality and performance. This study examines the market structure, conduct and their influence on the performance of the onion market in the southern part of Ghana, using data from 180 actors, comprising 80 farmers, 40 wholesalers and 60 retailers. Descriptive statistics, Gini coefficient, Lorenz curve, Herfindahl-Hirschman index and Garett ranking were the methods of analysis used. The results showed that traders were operating in an oligopolistic market with Gini coefficients of 0.62 and 0.56 for wholesalers and retailers, respectively. The findings also revealed that farmers (69%) were more open to contracts than wholesalers (20%) and retailers (11%). Moreover, onion production proved to be costly for farmers as they had a negative return of 1.55% on their investment while wholesalers and retailers made positive returns of 29.85% and 31.1%, respectively. Finally, high production cost, high marketing cost and unavailability of storage structures were ranked as the most pressing constraints to farmers, wholesalers and retailers, respectively. It is recommended that the government, donor support agencies for agriculture and local NGOs come to the aid of farmers by providing them with fixed assets at a subsidized price. This will relieve the farmers from heavy losses which threaten the future food security of the country.

Abstract

Along the maize value chain in Ghana are a wide range of risks that confront actors; the risk chain actors' face include production and marketing risks. Accordingly, risk management, which has become an integral part of maize value chain activities, is challenged with several factors, some of which are economic, institutional, social and behavioral factors. This study posits that risk preferences/behavior of farm decision-makers in the maize value chain have empirical importance for economic and policy analysis. Thus, an experimental gambling approach was used to elicit the risk aversion behavior of respondents (farmers). Here, the respondents' risk aversion behavior over varying game levels was investigated. The multinomial logit model was used to investigate endogenous and exogenous factors explaining the risk behavior. The data were obtained by interviewing 220 maize farmers who were sampled with a two-stage sampling procedure. This study revealed that most of the farmers in the study area exhibited risk aversion behavior. About 33% of farmers showed extreme risk aversion behavior at the games’ lowest level and increased to 45% as the game level rose. It was also found that sex, age, level of formal education, access to credit, access to the storage facility, household size, farm size and the number of extension visits to the farm significantly explained the risk aversion behavior the maize farmers exhibited. Because farmers are risk-averse and become more risk-averse as stakes become high, any farm innovations to be introduced to them must be implemented gradually, especially with the low-income farmers. It is also critical to make risk mitigation 'handles' available to farmers so that they can rely on them during times of risk.

Abstract

Aquilaria malaccensis Lamk. is one of the most widespread agarwood-producing plants that face extinction due to overexploitation. Agarwood propagation using in vitro culture techniques is capable of producing large quantities of plants in a shorter time and free from pests and diseases. Therefore, this study was conducted to analyze the effect of auxins type and concentration on agarwood plantlet formation using a split-plot design. The main plot was the type of auxin which included IAA, IBA and NAA, while the subplot was the concentration used which consisted of 0; 5; 10; 15 and 20 µM. The variable observed was agarwood plantlet formation with parameters measured including the number of shoots and leaves, plant height, and number of roots. The results showed that the formation of agarwood plantlets was controlled by the type, concentration, and interaction between the type and concentration of auxin. Furthermore, explants cultured on Murashige Skoog (MS) medium supplemented with 10 µM IBA produced the highest number of shoots (3.39 shoots explant-1) and leaves (7.25 leaves explants-1), while the addition of 10 uM NAA resulted in the highest number of roots (2.52 roots explant-1). This is the first time a study is conducted to evaluate the effect of type and concentration of auxins on agarwood plantlet formation. The production of high-quality shoots and plantlets increased agarwood germplasm availability to prevent extinction and support sustainable production.

Abstract

Endemic leaf rust disease always occurs in almost all maize plantations in Indonesia. Furthermore, the development of this disease differs concurrently and is greatly influenced by the ecological conditions of maize cultivation. Therefore, this study fills the epidemiological gap of diseases that has not been conducted against the epidemiology of maize rust. This identifies the causes of leaf rust that attacked the maize plants in two locations, namely Bayur and Muang Dalam, Lempake, Samarinda, Indonesia. This study also analyzed the relationship or model between ecological factors of temperature, humidity, and soil fertility on the intensity of leaf rust and the infection rate of maize leaf rust. Measurement of disease intensity, the rate at which it developed, soil fertility and temperature and humidity of the area are conducted in this study. Meanwhile, soil fertility also influenced disease progression and the nutrient-poor soils in two sites cause leaf rust disease to develop well. The identification results showed that the cause of maize leaf rust was Puccinia sorghi Schw. Therefore, the temperature accompanied by the increased humidity is directly proportional to the development of the leaf rust.

Abstract

Salinity is a challenge in crop production. High salinity affects soil osmotic pressure and the balance of nutrients that inhibit plant growth. In such case, utilization of salt-tolerant rice varieties could be an alternative. This study aims to identify microsatellite markers associated with salt tolerance, compare the Inpari Unsoed 79 Agritan variety with ten other rice genotypes based on microsatellite markers and determine the qualitative composition metabolites in Inpari Unsoed 79 Agritan associated with the plant response to salinity. This research was carried out at the Laboratory of Plant Breeding and Biotechnology Universitas Jenderal Soedirman and Indonesian Institute of Sciences, Bogor. This research used eleven rice varieties and ten microsatellite markers. The identification of microsatellite markers consisted of genomic DNA extraction, quantification and qualification of DNA, amplification of microsatellite DNA and data analysis. Metabolite profiling was conducted on Gas Chromatography-Mass Spectrometry (GC-MS) instrument. The results showed that microsatellite markers RM 241, RM 515, RM 519 and RM 528 differentiate the Inpari Unsoed 79 Agritan from the IR 29 genotype. Microsatellite markers RM 129 and RM 292 distinguished the Nona Bokra from the IR 29 genotypes. The genetic relationship of eleven rice genotypes resulted in two clusters. The GC-MS metabolite compounds in Inpari Unsoed 79 Agritan are β-Alanine and trimethylsilyl ester β-Alanine, a derivative compound of β-Alanine. These findings suggested that microsatellite markers RM 129, RM 292, RM 241, RM 515, RM 519 and RM 528 were associated with salt-tolerant in the seedling stage.

Abstract

Over the years, there has been a continuous increase in the demand for tef (Eragrostis tef (Zucc.) Trotter) due to population growth, average incomes and urbanization in Ethiopia, but its innovation system has not been fully explored. This research aims to determine the supportive effect of tef innovation system on its investigation and development as well as the systemic constraints in the process. A coupled structural-functional innovation system analysis was used to explore the barriers faced in Central Ethiopia. The results revealed the constraints affecting the innovation system, namely limited capacity of existing actors, weak interactions and partnerships among actors, weak enforcement of institutions as well as inadequate/poor infrastructure. They also showed that technology development, technology diffusion, entrepreneurial activities, market development, resource mobilization and legitimacy creation have been the weak functions of tef innovation. Furthermore, a failure in one of the functions has a knock-on effect on others, which causes an overall dysfunctional innovation system. Based on the results, failures of the structural elements along with weaknesses of functions have constrained the development of tef innovation systems sector. A combination of technological, institutional and technical intervention must be implemented to overcome this problem.

Abstract

The increasing demand for rice and the increasing population growth rate require sustainable rice production. Direct seeding of rice (DSR) combined with the use of arbuscular mycorrhizal fungi (AMF) is needed to achieve sustainable food production. This study aims to determine the effect of the planting method and mycorrhizal inoculation on the diversity, composition and dominance of weeds in a rice field for the sustainability of agricultural production. The research used a split-plot design with three replications. The main plot was the planting method consisting of on row, drum seeder and transplanting, while the subplot was mycorrhizal inoculation divided into with mycorrhizal inoculation and without mycorrhizal inoculation. The observed variables were light penetration, weeds population, weeds composition, weeds biomass, summed dominance ratio and community coefficient. The results showed that there were 34 kinds of weeds consisting of 13 families and the dominant weed was annual weeds, most of which were broadleaf weeds. The dominant weed was Alternanthera sessilis (L.) R. Br. ex DC. (sessile joyweed). The planting methods affected the weed population in 24 days after sowing (DAS) and the composition of broadleaf weeds in 24 DAS but did not affect weed biomass. The AMF inoculation did not affect weed population, composition, or biomass. It is necessary to find mycorrhizal species that can affect weed growth.

Abstract

Seedlings is the initial part of seed plant’s growth and development including areca nut palm which germination is an essential part of it. Organic mulching is one of the utmost sustainable practices, therefore, it has been employed to enhance areca nut seedlings growth. The study aims to evaluate the effect of several types of organic mulch on areca nut seedlings shoot-root growth. The 3-month long experiment was conducted according to completely randomized design, with four treatments, namely no mulching (control) (M0), gliricidia (Gliricidia sepium) mulching (M1), imperata (Imperata cylindrica) mulching (M2) and lamtoro (Leucaena leucocephala) mulching (M3). The treatments were repeated 5 times with 20 experimental units. The findings revealed that no significant differences (p < 0.05) were found on the application of different organic mulching among all of the parameters. The treatment covered by imperata mulch tended to score the highest compared to other mulches on germination time, seedling height and shoot fresh weight while the minimum yield was recorded in M1 where gliricidia mulch was used. Application of organic mulch displayed better results for most of the parameters than that of the control resulting from an optimal growing environment for areca nut seedlings growth.

Abstract

The Klampok Sub-watershed flows in the Semarang Regency, Central Java, Indonesia, located in the upstream part of the Jragung Watershed, used as a source of irrigation. Klampok Sub-watershed experiences environmental pressures in the form of decreasing water quality because of various human activities. For this reason, this study aims to determine the changes in the water quality and pollution index of the Klampok Sub-watershed in 2016 and 2020. The water quality observations were carried out in 2020 utilizing the Total Suspended Solids (TSS), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Nitrate, Zinc (Zn) and Copper (Cu) parameters. The laboratory analysis results were compared with water quality standards based on Government Regulation Number 22 of 2021 and the status of water quality based on the pollution index method under the Decree of the Minister of the Environment Number 115 of 2003. The study results showed a change in the quality and index of water pollution in 2016 and 2020. The study results revealed a decrease in the value of water quality on the parameters BOD, COD, Zn and Cu, which indicated that the water quality was improving. Moreover, the Klampok Sub-watershed pollution index decreased in 2016 and 2020 so that the Klampok Sub-watershed had quality criteria for lightly polluted water to moderately polluted to lightly polluted at each sampling point. Therefore, several efforts to control pollution and management of the Klampok Sub-watershed, such as community outreach, water quality monitoring and industrial compliance, are expected to improve so that the Klampok Sub-watershed's sustainability can provide various benefits to the community.
