Abstract:Cricket is widely recognized in Indonesia especially in Java island, and commonly kept by village farmers for food and feed. In general, crickets has very short life cycle (60-70 d), with three weeks of laying period and egg production within the range of 200-1,500 eggs/female. The female has capability for multiple mating with several males and therefore produces more fertile eggs. Serial studies including experiments on laboratory and field observation of local crickets had been conducted to evaluate the farming practices and reproductive performance of three local species (Gryllus spp., Gryllus mitratus and Gryllus testaceus) which were given local feeds-Manihot esculenta and Carica papaya leaves. The experiment was conducted in randomized block design with feed as the treatments and species as the block. Cliring crickets (G. mitratus) fed with M. esculenta leaves revealed the highest total egg production (1,478.22 eggs), with daily egg production of 32.85 eggs/d, the longest laying period (45 d), the lowest feed intake (0.28 g/head) and feed conversion (0.93 mg/egg), compared to Cendawang crickets (G. testaceus) and Gryllus spp.. The revenue and cost (R/C) ratio was 1.4, indicating that small scale cricket enterprise could offer significant profit and could be chosen as an alternative activities for earning regular income.
The soybean harvested area in Banten Province in 2018 was 23,594 ha with a production of 18,093.6 tons with productivity 0.77 ton/ha, xx. The main center for soybean plants is in Pandeglang Regency with an area of 18,925 ha and production of 14,115 tons. The objectives of this study are: 1) analyzing the performance of soybean farming, 2) analyzing the factors that influence soybean production and, 3) analyzing the level of prices efficiency/allocative of soybean production. The sampling method used purposive random sampling. Data analysis used descriptive tabulation and Cobb Douglas production function. The results of this study were: 1) The cultivated varieties were Anjasmoro (51.7%), Grobogan (44.8%), and Detap (3.5%). Soybean farming income is IDR. 4.038 million/planting season with a B/C ratio of 2.2. 2) Factors that significantly influence soybean production are the amount of use of NPK fertilizer, other fertilizers, liquid pesticides, hired human labor, and the area of cultivated land. 3) It was shown that none of the production factors is inefficient in price (NPMx/Px ≠1). The average value of Price Efficiency is 17.826, which means that the use of production factors is not efficient, it needs to be increased in use.
Uniformity of cocoon weight is one important factor of parent stock in order to get a good quality of crosses. In consequence, some cocoons that too heavy or light become wastes even come from a good strain. The research that conducted at Forest and Nature Conservation Research and Development Center, Bogor, had an objective to know the effect of parent cocoon weight on the egg and larval quality among four reciprocal crosses. Strain 803 (Japanece race) and strain 804 (Chinese race) with different cocoon weight were used as parent stocks. The effect of cocoon weight was evaluated on the economical traits including number of eggs, weight of eggs, hatchability, weight of newly hatched larvae and hatching period through crossing method, wherein parents, F1s and reciprocals were involved. The result showed that number and weight of eggs were significantly different. Maximum number of eggs and maximum weight of eggs were 650 and 0.61 mg, respectively, that belongs to (803 B x 804 B ), heavy cocoon of 803 female crossed with heavy cocoon of 804 male. Strain 803 female influenced those characters. Types of crossing had not an effect on hatchability, weight of newly hatched larvae and hatching period.
This research aims to determine the best ventilation modification to produce propolis. The study was conducted at the foot of Mount Tampomas, Sumedang, West Java, in 5 weeks from July to August 2013. The material used were 15 hives of Apis mellifera honey bee colony with population 16 000-20 000 bees. The 15 colonies were randomly divided into 3 levels treatment of ventilation size on the lid nest, that were no ventilation as control treatment (A), 50 cm 2 (B), and 100 cm 2 (C) ventilation holes. Propolis trap was installed in each hive. The experimental design used was completely randomized design followed by T-test. The results showed that ventilation size was not significantly affected propolis production but significantly affected honey production. Honey production in C treatment was significantly higher. In general the best treatment hive cap to produced propolis and honey are C treatment with the highest average weight of propolis and honey for 5 weeks was 16.4±6.98 g and 3101.6± 581.5 g also have a big end population.
In 2019, chili production in Banten province amounted to 12,122.9 tons with a harvest area of 1,395 ha or productivity of 8.7 tons/ha. The objectives of this study are: 1) Analyzing the factors affecting the cultivated land area and chili production in Banten Province, 2) Analyzing the impact of increasing input and output prices on chili production in Banten Province. This study method used a survey method with 80 respondents. The analysis method uses the Simultaneous Equation Model. The results of the study were 1) The factors that significantly influence the cultivated land area of Rainy Season (RS) 2015/2016 were the number of: manure, solid organic fertilizers, other fertilizers, solid leaf fertilizers, and the total land area. The factors that significantly influence chili production in Banten Province are the number of: KCL fertilizer, liquid leaf fertilizer, and liquid growth stimulant. 2) From the policy simulation results, it is known that an increase in chili prices by 25%, Urea fertilizer by 25%, and NPK by 25% simultaneously will reduce production by 2.8% and chili farming income by 16.2%, but increase the area land 5.8% and farmer household income 0.06%. The government needs to stabilize the chili price and maintain the subsidized fertilizer price.
