Abstract

Land is an essential component for the sustainability of human life. Population growth and urbanization affect the availability of land in an area. Therefore, the land never increases, but the need for land continues to grow every year, converted to housing and other facilities. As an area that continues to develop, Klungkung Regency has decreased the availability of land due to development and investment activities, especially tourism investment and the construction of other supporting facilities for tourism and regional development. Therefore, the availability of land in Klungkung Regency continues to experience pressure, which impacts the ability to provide food. This study aims to determine land requirements, land availability, and land carrying capacity status in Klungkung Regency, which the policy-makers can consider to support food sustainability in Klungkung Regency. This study uses a quantitative approach using primary data from direct observations in the field and secondary data from government and previous research. The results show that the carrying capacity of land in the Klungkung Regency is in deficit based on the projections for 2021 to 2030. In overcoming the land deficit, it is necessary to increase land productivity by using land effectively and technology transfer to increase food productivity. Keywords: carrying capacity, food sustainability, Klungkung Regency land conversion

Abstract

This study evaluates the feasibility of integration of the single-bud sugarcane and catfish farming system and the growth rate of both plants and fish. The observation started from September to November 2020. The design used was randomized with one factor. The treatments used were cultivation of single-bud sugarcane in polybags, hydroponic single-bud sugarcane cultivation, integration of single-bud sugarcane-catfish, and catfish cultivation. The results showed that the growth of sugarcane seedlings and the catfish indicate that the integrated cultivation system of sugarcane-catfish is feasible to apply. Such an integration system produces a better number of leaves, stem diameter, leaf area, and root length than the cultivation system of sugarcane seedlings in polybags. The weight of the canopy and the root of sugarcane seedlings in the integration system is also noticeable greater than the sugarcane seedlings cultivated in the polybag. In addition, the rate of catfish growth in the integration system is better than catfish's ordinary cultivation. Keywords: hydroponic, integration farming system, single bud sugarcane planting

Abstract

The use of habitat by fish is closely related to efforts to find the best conditions for the survival of these fish. This study aims to analyze the habitat preferences of Striped snakehead in Rawa Aopa waters, Southeast Sulawesi. This research was conducted from November 2018 to February 2019 in the waters of Swamp Aopa Southeast Sulawesi. Fish collection using traps. The constancy and fidelity index determined the preference of striped snakehead for habitat type. A total of 1024 striped snakehead fish were caught during the study with a length range of 200,0-420,0 mm and 69,0-596,0 g weight. Striped snakehead measuring 200-367 mm were consistent in occupying habitats with a slightly dense to dense water plant density, while sizes 368-388 and 389-430 mm were consistent in habitats with sparse water plant density. The preference level of striped snakehead fish size 389-430 mm to habitats with rare aquatic plants is very high (Fij = 6). Therefore, the size can be used as an indicator of habitats with the rare aquatic plant category. The preference for 200-367 mm striped snakehead fish in dense aquatic plant habitats indicates that these habitats are foraging, growing, and protective zones. Keywords: Channa striata, fish habitat, Rawa Aopa, Southeast Sulawesi, stripe snakehead

Abstract

The presence of new pest Spodoptera frugperda J. E. Smith has the potential to reduce corn production, so its existence needs to be controlled. The aim of this research is to obtain control techniques that could reduce the intensity of S. frugiperda pest’s attack. The research was conducted from June to October 2020. The experiment was designed in a randomized block design (RBD) with 9 replications and 3 treatments consisting of non-control (NP), PHT-biointensive (BI), and synthetic pesticides. In BI treatment, neem leaf extract (25 mL/plot) and Beauveria bassiana (6,25 g/plot) were used. Meanwhile, the PS treatment used deltametrin active ingredient (3,125 mL/plot). The volume of spray used was 1,25 L. The results showed that PS control techniques gave the best results in suppressing the intensity of fall armyworm S. frugiperda attacks (0,57%-7,04%) followed by BI treatment (0%-6,89%) and NP (0,97%-8,29%). The highest pest populations overall were found in NP treatment and the lowest in PS treatment. PS treatment provided the highest production result with a cob weight of 18,6 kg/plot (24,81 tons/ha), while BI treatment of 17,00 kg/plot (22,72 tons/ha) and NP of 15,44 kg/plot (20,64 tons/ha). The results of the correlation test between the intensity of pest attacks and production results showed that the higher the pest attack, the lower the harvest weight produced. Therefore, pest control by using synthetic pesticides made from active deltametrin is declared effective in suppressing the intensity of attacks and populations of fall armyworm S. frugiperda and able to provide high production results. Keywords: corn, intensity of attack, Spodoptera frugiperda

Abstract

Silicon (Si) has an important role in the growth of rice plants and some soil chemical properties. However, Si still receives less attention, because there is still little information about the importance of Si for rice plants and not many researches have been done on the use of Si in rice plants. This condition causes the farmers do not practice the use of Si as a fertilizer that eventually removal or release of silica from the soil solum. One source of Si that can be used as a fertilizer is trass. Currently, the trass has been widely used by the community as the basic material for making bricks. However, the use of trass as a source of Si in agriculture is not widely known. Therefore, it is necessary to evaluate the effect of trass on rice plant growth and soil chemical properties. The purpose of this study was to analyze the effect of trass addition on soil chemical properties and rice growth. The experimental design used was a separate plot where three types of soil, namely oxisol, inceptisol, and vertisol as the main plot and seven doses of trass were 0 (D0); 1.25 (D1); 2.5 (D2); 3.75 (D3); 5 (D4); 7.5 (D5); and 10 (D6) g kg-1 of soil as sub-plots. The treatment was a combination of these two factors and was repeated 3 times to obtain 63 experimental units. The results showed that the administration of trass significantly increased pH, available P, Ca-dd, Mg-dd, and significantly decreased available Fe and Mn. Meanwhile, the provision of trass also significantly affected plant height, namely 91 cm, and the number of tillers, namely 21 stems. Key words: chemical properties, rice, silicon, trass

Abstract

Zn levels in rice are essential for maintaining consumer health. However, Zn deficient plants can reduce levels of Zn in grains and the ability of plants to express their genetic potentials. This study examines the use of cow manure enriched with Zn heptahydrate on increasing Zn levels of broken skin rice. The experiment was arranged in a randomized single factor group design with seven levels of manure dose treatment, namely: 0; 2.5; 5, 7.5, 10, 12.5, 15 tons ha-1, with 3 replications. Spacing was 30 cm x 30 cm with a size of 3 m x 4 m. The parameters observed were plant growth, the weight of 1,000-grain, percentage of empty grain, production, Zn and protein contents of the brown rice. The collected data were analyzed using analysis of variance with a confidence interval of 5%, followed by the Duncan test of 5%. The results showed that the application of cow manure with a dose of 10 tons ha-1 enriched by 5 kg ha-1 Zn heptahydrate could increase the number of productive tillers, weight of 1,000-grains, production, Zn and protein contents of the brown rice as well as suppress the grainy rice grain of Mekongga variety of lowland rice on the intermittent flooding. Keywords: brownrice, cow manure, irrigation system, Zn heptahydrate

Abstract

The low area for soybean plantation is still a major problem in meeting soybean needs. One of the efforts to increase national soybean production is by expanding the planting area by utilizing the sandy soil area that is still not used for soybean cultivation. This research was conducted from September-November 2020 in a greenhouse of the Agronomy Laboratory, Bengkulu University. This study aims to obtain the best dose of urea and vermicompost for the growth and yield of soybean in sandy soil. The research design used a completely randomized block design with two factors and 3 replications. The first factor was the dose of urea consisting of four levels, namely U0 = 0 kg ha-1, U1 = 50 kg ha-1, U2 = 100 kg ha-1, and U3 = 150 kg ha-1. The second factor was the dose of vermicompost, namely K0 = 0 ton ha-1, K1 = 5 tons ha-1, K2 = 10 ton ha-1, and K3 = 15 ton ha-1. The measured variables were the plant growth and the yield. Soil and vermicompost analyses were carried out before the study. The results showed that there was an interaction between the vermicompost and the urea dosages. The 100 kg ha-1 urea and the 10 ton ha-1 vermicompost treatment gave the highest plant height. The 150 kg ha-1 urea dan the 15 ton ha-1 vermicompost treatment formed the most number of branches. The highest soybean yield was given by 15 ton ha-1 vermicompost and 50 kg ha-1 urea to the total pod and the seed weight. Keywords: sandy soil, soybean, urea, vermicompost

Abstract

Cow/buffalo-business insurance (AUTS/K) is a form of risk mitigation for livestock businesses run by farmers. Various risks that are often occurred include livestock death, natural disasters, disease outbreaks, and livestock theft. If not handled properly, it can threaten the sustainability of this business, especially the small-scale livestock-business sector. This study aimed to formulate a developing system of cattle/buffalo-livestock insurance using the soft-systems methodology (SSM) approach. This research was conducted in Aceh Province from December 2020 to February 2021 using an expert survey by collecting data and information through parties who have competence or expertise in the field being studied. The development of this insurance system can be said to be an effort to improve and a solution to any problems currently being experienced in the implementation of AUTS/K. The result of improvements includes optimizing the roles of each party involved and program innovation to intensify AUTS/K products among breeders. The results showed that the SSM approach could describe the problem well and form a conceptual model for the AUTS/K system in Aceh province. Improvements to policies, assistance, and promotion systems are recommended as solutions to the problems related to livestock-insurance system implemented. Keywords: breeders, conceptual model, insurance system, soft-systems methodology, syariah insurance
