Abstract

The scarcity of fuel oil in the future needs to be anticipated by preparing alternative energy. One of the alternative energy sources developed is Jatropha. However, the development of Jatropha should use marginal land as a cultivation area, like a dry land, because the food crops and horticulture use productive land for cultivation. Furthermore, Jatropha development through breeding is an effort to obtain superior varieties as biodiesel producers. This study aimed to determine the best phenotype characteristics of hybrid Jatropha plants as superior candidate trees. This research applied a descriptive qualitative method to determine the characteristics of Jatropha crossing results. The Jatropha characterization was conducted at the experimental garden of Kedung Pengaron Village, Kejayan Sub-district, Pasuruan Regency. The experimental garden was included dry land for Jatropha cultivation. The result showed ten selected genotypes of hybrid Jatropha were found, including 05.01.01, 05.01.02, 05.02.02, 05.02.09, 05.03.17, 05.03.16, 05.04.16, 05.04.15, 06.01.02, 06.01.15. These were based on the two-phase observations, consisting of vegetative and generative observations. The plants’ morphological characters were observed, comprising the stems, leaves, flowers, fruits and seeds. In the vegetative phase, diversity was found in the number of leaves, leaf length and age of flowering, while in the qualitative phase, the shoot colors were more diverse. Moreover, less variations were figured out in the color character of the petiole and the number of shoots. These ten genotypes of hybrid Jatropha are the best genotypes that are resistant to drought with selected agronomic characters.

Abstract

The fluctuation of potato production has been caused by production risk in on-farm sector. This research aims to identify the sources of production risk in potato production and analyze the strategies to overcome the production risk. This research was conducted at Cantigi Farmers’ Group, which has been actively producing potato in Cikajang Sub-district, Garut Regency, West Java. The data were collected from all 35 members of the Cantigi Farmers’ Group. This study used Z-Score and Value at Risk analyses. The results showed that the sources of potato production risk that occurred in the Cantigi Farmers’ Group were pests, diseases, rainfall, seed quality, managerial ability and soil fertility. Mitigation strategies can be used to overcome the risk sources such as by using intercropping method, plant-based pesticides, natural enemies, proper water management and drainage. Preventive strategies can be used to overcome the risk sources such as by using plant-based pesticides, organic fertilizers, assistance from local extension agents, in collaboration with certified seed breeders in the surrounding area and attending the training of how to breed properly. The research on potato production risk in Cikajang Sub-district is very significant considering that, to the best of authors’ knowledge, the analysis of potato production risks has not been conducted yet in this important area of potato producing. This study was conducted in a limited scope of variable, therefore, a further research of potato production risks is suggested to be performed in a wider variable scope.

Abstract

Indonesia's trade balance to India had been decreasing since 2013. That has been affected by the downward trend in agricultural export value of Indonesia. This problem has raised Government’s attention to increase the export performance. This research aimed to analyze the determinants of Indonesia’s leading agricultural commodities export to India. Panel data regression model was explored to analyze secondary data of the range year 2001 to 2017. The factors examined in this study were India’s real Gross Domestic Product (GDP) per capita, Rupiah exchange rate, export price of Indonesia agricultural commodities and India’s import tariff. Model testing used the Chow, Hausman and Lagrange tests to compare and select the best model. The determinant of the variables testing used statistical and classical assumption tests. The results showed that India’s real GDP per capita has positive influence to the export value which means an increase in the purchasing power of trading partners would increase the value of exports. The Rupiah exchange rate has negative influence to the export value which means that the depreciation of rupiah to dollar causes a decrease in the export value. The export price of Indonesia’s agricultural commodities have positive influence on the export value, however the tariff has no effect. The policy that can be suggested to the government is to provide support and encourage domestic producers to increase exports to India.

Abstract

There are two symptoms of wilting in banana plants that have been widely known, namely fusarium wilt and bacterial wilt. The symptoms of banana wilt usually are attributed to pathogenic fungi. Wilting symptoms on the leaves are usually accompanied by leaf spot, leaf streak, leaf speckle and anthracnose. Recent quarantine pest reports have found the symptoms of banana wilt in Morotai Island, Indonesia. The pathogens attack many local cultivars of banana plants including Mas, Ambon, Kepok and Nangka. The study aimed to establish the morphological characters of the pathogens that cause banana wilt. Descriptive research began with the sampling of diseased symptomatic leaves, field data reports and identification of pathogenic morphological characters in the laboratory. The variable observed were the disease symptoms, color and shape of mycelia, conidia, kinds of the pathogens and their growth on agar medium. The results showed that there was no quarantine pest on the symptomatic banana samples. There were two non-quarantine pests that had been identified, i.e Fusarium oxysporum causing fusarium wilt and Cladosporium musae causing leaf speckle.

Abstract

Nuabosi cassava is an alternative carbohydrate source for the community, which is expected to be a substitute for rice. This commodity has the potential to be developed, but is limited in resources, so it requires technological breakthroughs. This study aims at analyzing the level of technical, allocative and economic efficiency between the cassava cropping pattern and the factors that affect the efficiency. The research was conducted in Randotonda Village, from November 2019 to January 2020 and the samples consisted of 61 monoculture farmers and 46 multiple cropping farmers. Data analysis was performed using the Cobb-Douglass stochastic frontier production function. The allocative and economic efficiency was examined with the stochastic frontier cost function approach. The results of stochastic frontier estimation show that all variables have a positive effect on the production variable. The variables having a positive effect on the total cost include the price of cassava cuttings, the price of fertilizer, production and the dummy cropping pattern. The average level of economic efficiency of monoculture farmers is lower than that of multiple cropping farmers. Factors that affect economic efficiency are age, length of time to cultivate, frequency of obtaining information, dummy of farmer group membership and dummy of cropping patterns. In short, the level of technical, allocative and economic efficiency of monoculture farmers is lower than that of multiple cropping farmers. Farmers are expected to pay attention to the types of plants that are suitable in implementing the multiple cropping pattern.

Abstract

The participation of women in the agricultural sector has increased in the last two years, attributed to the population growth and household economy. Therefore, this research examined the internal and external factors to the women farmers’ participation. This research was conducted in Situ Gede Village, West Bogor Sub-district, Bogor City and involved women farmer group consisting of 36 members. The primary data were gathered by interviewing respondents using a questionnaire, while the secondary data were obtained from literature review and various related institutional sources. The data were examined using the Pearson’s Product-Moment Correlation analysis to investigate the relations between the internal and external factors to women farmers’ participation. The results of this study have revealed the internal factors related to women farmers’ participation, such as age, farm experience and decision making. Meanwhile, the external factor related to the participation of women farmers is the access to counseling, meaning that some of these aspects need to receive the government’s attention, especially in terms of access to education related to the counseling method, time and substance of counseling.

Abstract

Market demand for chilies continues to increase, so efforts are needed to increase the productivity of the chili plants. One of the efforts is by intensifying production factors such as applying fertilizers on beach sand which contain low nutrients and organic matter so that manure input is needed and also utilizes soil microbial technology in the form of arbuscular mycorrhizal fungi which are relatively cheap economically and environmentally friendly. The purpose of this research was to study the effect of types of manure and mycorrhizal applications on the growth and yield of curly red chili. The research was arranged in a strip-plot Randomized Completely Block Design (RCBD) consisting of two factors with three replications. The first factor is the type of fertilizer (cow manure, chicken manure, guano fertilizer, quail manure and urea fertilizer) and the second factor is the application of mycorrhizae (with and without). This study concludes that quail manure increases plant height. The addition of chicken manure, guano fertilizer and quail manure multiplies the total fruit production. The application of mycorrhizae gives the same results on the growth and yield of chili.

Abstract

Spent Bleaching Earth (SBE) is a by-product of the refining of Crude Palm Oil (CPO) into cooking oil which is classified as hazardous and toxic materials waste. SBE has the potential to be used as a filler in the production of NPK fertilizer. This study aims to compare the effect of SBE and Deoiled Bleaching Earth (DBE) as the replacement of clay mineral, which is expected to have the same effect as the control treatment in terms of the leaf area, total dry weight, plant height and yield of plant. This experiment used a one-factor Randomized Complete Block Design (RCBD) with three replicates. The treatments of filler in NPK fertilizer were 10% clay minerals, NPK with 5% clay mineral + 5% SBE filler and NPK with 5% clay mineral + 5% DBE filler. Fertilizer was given twice, ie when the plant was 14 days after planting (DAP) as much as 2 g polybag-1 and age 35 DAP as much as 3 g polybag-1 at each treatment. The results showed that the application of NPK fertilization with 5% clay mineral + 5% SBE filler and NPK fertilization with 5% clay mineral + 5% DBE filler had the same effect as NPK fertilization with 10% clay mineral filler on leaf area, total dry weight, plant height and yield of plant. SBE and DBE can be used as substituties for clay mineral in NPK fertilizer production.

Abstract

Soilless culture system (SCS) production is preferred because it is more hygienic and highly nutritious and free of chemical pesticides. However, the application of organic fertilizers in SCS for green vegetable cultivation is still rarely used. This study was to test various growing media compositions and vermicompost rates on green lettuce's nutritional quality. Four types of growing media (using the mixture of cocopeat, zeolite, rice husk biochar and sand) and five levels of vermicompost rates (50-250 g pot-1) were tested. The greatest total fresh weight and marketable yield were found using 55% cocopeat, 30% rice husk biochar and 15% sand with a vermicompost rate of 250 g pot-1. The highest nutritional quality of green lettuce as measured by the highest content of chlorophyll A, B, the total chlorophyll and calcium (Ca) was found in the composition of cocopeat 55%, zeolite 30% and sand 15%. As was, the highest mineral content of of potassium (K) and phosphorus (P). Good quality lettuce was found in growing media using 30% biochar with a vermicompost rates of 200-250 g pot-1 and growing media using 30% zeolite with a vermicompost rates of 150-200 g pot-1. Thus, the admixtures of biochar and zeolite into the cocopeat substrate for the soilless culture system of green leafy lettuce significantly affected yield and nutritional quality.

Abstract

Over the past few decades, agricultural land sustainability on the peri-urban areas face a threat to the agricultural land conversion, especially on the peri-urban areas of Pekalongan City. The sustainability of agricultural land is determined by the level of farmers’ perception. Therefore, this research was conducted to determine the factors that influence farmers’ perceptions toward agricultural land sustainability in peri-urban areas of Pekalongan City. The peri-urban areas of Pekalongan City were selected by purposive sampling method with a total sample of 90 farm owners and cultivators. Data were analyzed using OLS (Ordinary Least Square) regression model. The results have shown that the factors influencing farmers’ perceptions toward agricultural land sustainability in the peri-urban area of Pekalongan City were farmers’ knowledge, farmers’ land tenure and access to information. Based on the results of the study, the variables of farmers’ knowledge and land tenure had a negative impact, while the access to agricultural information had a positive impact on farmers’ perceptions. These results have the implication for farmers, that their perceptions can be improved by making advances to the quality of agricultural land in the suburbs, reducing both production and price risks and increasing the intensity of counseling or training related to agricultural activities in the suburbs of Pekalongan City.
