Abstract

Crickets are the most demanded commodity because there have the most interest in ornamental livestock such as birds, while the presence of crickets in nature has diminwashed because their natural habitat has been increasingly eroded by city development. The important thing to consider in cricket farms was when incubating cricket eggs which requires special treatment to maintain their temperature and humidity. Thwas study aims toknow the hatching ability of cricket, egg hatching duration and the vitality of honey cricket age 0-10 days, in different media. The research was conducted at the Biology Laboratory of Animal Husbandry Study Program, Faculty of Agriculture, Universitas Sumatera Utara, Jl. A. Sofyan No. 3 Medan, which started from November 2018 until December 2018. The design used was a completely randomized design (CRD) 4 treatments (Q0: river sand hatch media; Q1: sand hatch media; Q2: kapok hatch media; Q3: rice straw hatch, and 5 replications (each conswasting of 100 honey cricket eggs Grylus mitratus).The use of various media for honey cricket hatching eggs has a positive influence on the hatchability of eggs, the duration of hatching eggs and the vitality of honey crickets tillers. River sand hatching media (P0) is the best hatching media for the parameters of hatching eggs of honey cricket and the vitality of honey crickets tillers.

Abstract

Mung bean need phosphate in seed formation and accelerate pod maturity. In acidic soil the P element is difficult to be available because it is bound by metal metals in the soil, it is given a palm bunch ash containing a lot of organic nutrients to release P from the metal and also increase soil pH. The study aims to determine the effect of P fertilization and palm bunch ash on the growth and production of mung bean. The study was conducted on community land in Medan Selayang from October to December 2019. The study used a factorial randomized block design, with 2 factors. The first factor is P fertilizer (0; 37.5; 112.5 kg SP-36/ha). The second factor is oil palm bunch ash consisting of 0; 2; 4 t/ha. The variables observed were a number of pods, weight of 100 seeds, weight of seed per plots, weight of seed per plant. The results showed that the application of P the applications of P fertilizer 112.5 kg SP-36/ha tended to produce the highest pod number and seed weight per plot. The applications of oil palm bunch ash 2 t/ha significantly increased seed weight per plant, seed weight per plot and pod number.

Abstract

The success of agricultural development in Indonesia in developing the ability of farmers is inseparable from the role of extension services carried out professionally. This study aims to (1) Analyzing the level of farmers 'perceptions about the role of extension workers in improving the competence of rice farmers in Tayawa Village, and (2) Analyzing factors that influence the level of farmers' perceptions about the role of extension workers in increasing the competence of rice farmers in Tayawa Village. This research uses a survey method with a descriptive analysis approach and a quantitative paradigm, supplemented with qualitative data information to support and sharpen quantitative analysis. The level of competence of middle rice farmers tends to be low, due to the weak role of agricultural extension workers. The role of the instructor as a communicator, facilitator, educator, and communicator turned out to have a positive effect on increasing the competence of rice farmers. But now these factors tend to be low so that it is still lacking in efforts to increase the competence of rice farmers.

Abstract

Coffee export activities in North Sumatera can be carried out using a variety of transaction systems. However, any transaction system has risks that may occur at any time. Risk management must be applied in coffee export activities. One common method used to manage risk is to use insurance services. This study aims to identify the type of transaction system that used by coffee exporters in North Sumatera Province, then analyze the risks that can occur in coffee export activities in this province and analyze the amount of insurance premiums on coffee export activities there. The location of the study was intentionally determined, namely in the North Sumatera Province. The research sample was 30 active exporters registered with the Indonesian Coffee Exporters Association of the North Sumatera Regional Board, determined by census. Primary data collected using a questionnaire and secondary data obtained from documentation. Transaction system identified using descriptive methods, while risk analysis is by calculating the risk score value. As for calculating the amount of insurance premiums carried out using Black-Scholes. The results found that there were three transaction systems that were used by research respondents in exporting coffee, namely letters of credit, advance payments and open accounts. Open Account is used by all respondents. While the export risk which is a priority risk in this research is at the risk of production. The average value of insurance premiums obtained using the Black-Scholes method is 7.82 percent of the total coverage.

Abstract

In slaughterhouses the burden of waste such as excessive blood volume causes  waste process with sewage treatment pond cannot work optimally. Blood should be separated and processed into other products such as blood meal. This study aims to prove that addition of blood meal produces good quality organic fertilizer. In this research, the fermentor used in the composting process was biogas slurry. The study used CRD (Complete Randomized Design) with 4 treatments: without blood meal; blood meal 6.5%; blood meal 13% and blood meal 19.5%. There was no difference between the treatments at fertilizer temperature, pH and C/N except treatment 19.5% blood meal on C/N. Application of blood meal by 19.5% in the fourth week on C/N was 12.17 as a requirement for mature fertilizer. The treatment by adding 375 g blood meal on 6 kg livestock feces and 6 kg feed leftover while use biogas slurry as the fermentor was a novel organic fertilizer formula.

Abstract

Stability analysis identifies the adaptation of a crop genotype in different environments. The objective of this study was to evaluate promising rice genotypes for yield stability at different mid-hill environments of Nepal. The multilocation trials were conducted in 2017 and 2018 at three locations viz Lumle, Kaski; Pakhribas, Dhankuta; and Kabre, Dolakha. Seven rice genotypes namely NR11115-B-B-31-3, NR11139-B-B-B-13-3, NR10676-B-5-3, NR11011-B-B-B-B-29, NR11105-B-B-27, 08FAN10, and Khumal-4 were evaluated in each location. The experiment was laid out in a randomized complete block design with three replications. The rice genotype NR10676-B-5-3 produced the highest grain yield (6.72 t/ha) among all genotypes. The growing environmental factors (climate and soil conditions) affect the grain yield performance of rice genotypes. The variation in climatic factors greatly contributed to the variation in grain yield. Polygon view of genotypic main effect plus genotype-by-environment interaction (GGE) biplot showed that the genotypes NR10676-B-53 and NR11105-B-B-27 were suitable for Lumle; NR11115-B-B-31-3 and NR11139-B-B-B-13-3 for Pakhribas; and 08FAN10 and NR11011-B-B-B-B-29 for Kabre. The GGE biplot showed that genotype NR10676-B-5-3 was stable hence it was near to the point of ideal genotype. This study suggests that NR10676-B-5-3 can be grown for higher grain yield production in mid-hills of Nepal.

Abstract

Okra (Abelmoschus esculentus L. (Moench) is one of the most important vegetable crops grown in Nepal. The crop is susceptible to various insect pests of which jassids (Amrasca biguttula biguttula Ishida.) is most predominant which reduces production and deteriorates seed quality of okra. A field study was conducted at Horticulture Farm, Agriculture and Forestry University, Rampur, Chitwan, Nepal to elucidate the effect of sowing date and nitrogen levels on the population and damage of jassids from April to September 2018. Three levels of nitrogen (100, 200 and 300 kg N ha-1) and five sowing dates (8th April, 20th April, 2nd May, 14th May and 26th May, 2018) were evaluated in randomized complete block design with three replications. Results indicated that the highest damage score was recorded in okra which was sown on 8th April (2.39) followed by 20th April (2.31) and 2nd May (1.26). The highest damage score of jassids was obtained with the use of nitrogen at the rate of 200 kg ha-1 (1.94) followed by 300 kg/ha (1.72) and 100 kg ha-1 (1.54). Mean population of jassids was maximum with okra sown on 20th April (29.91) and minimum with okra sown on 26th May (6.95). This study showed that late planting i.e. 26th May and applying low level of nitrogen i.e. 100 kg N ha- 1is an effective approach for reducing the jassids population and its damage in okra.

Abstract

One of the main problems in rice cultivation is the difficulty of controlling bondol bird (Lonchura punctulata) pest attacks. Bird pest is one of the main enemies of farmers that can reduce crop production. Increasing bird populations cause crop yields to decline. So that one way that can be used in repelling bird pests is by giving pesticides from garlic extract. Allicin is a compound that gives garlic its distinctive smell which repels bird pests. This study aims to determine the effect of the provision of plant-based pesticides from garlic extract in repelling rice-eating bird pests. This research was conducted in Tonasa Village, Takalar District, South Sulawesi, Indonesia. Research implementation methods include the manufacture and testing of pesticides liquid extracts of garlic and application in the field by spraying, this spraying is carried out in the morning, afternoon, and evening before making the observations. Observation parameters use the method of comparing initial observations and final observations observed in the morning, afternoon and evening (comparison method) by conducting initial data collection (without using pesticides) and final data collection (after spraying pesticides), the average number of groups of birds that attack 1 Ha of rice fields. The results obtained on average indicate quite a lot of attacks in a day, especially in the morning. After the use of the automatic repellent method the attacks of bondol bird groups tend to decrease where in the morning ratio of 20 to 33 decreases to 5 to 13 attacks, while the ratio of daytime 8 to 15 decreases to 3 to 7 attacks and the ratio of the evening 19 to 33 decreases to 6 to 12 bird group attacks. So that the administration of garlic extract pesticides is effective in reducing bird pest attacks.
