Abstract

The constraints in the cultivation of banana plants is the high number of pests that damage plants in vegetative vases. The study was conducted in the Farmers' Land Group of the United Society of Sampali Village, Percut Sei Tuan District, Deli Serdang Regency in May-July 2019. The research method used was descriptive analysis method using (random sampling). Observation parameters consisted of population density, pest attack rate, egg parasitoids, larva parasitoids, pupa parasitoids, parasitoids identification, species diversity index, species evenness index, and relative abundance. There are 4 types of parasitoids namely Braconidae sp 1 (Hymenoptera: Braconidae), Tachinidae sp 1 (Diptera: Tachinidae), Xanthopimpla gampsura (Hymenoptera: Ichneumonidae) and Brachymeria lasus Walker (Hymenoptera: Chalcididae).

Abstract

The study aimed to determine the response of growth and production of peanuts to the provision of goat manure and banana hump liquid organic fertilizer. This study used a Randomized Block Design (RBD) with 3 replications. Factorial consisting of II treatment factors, Factor I treatment of giving goat manure and Factor II, the treatment of Hump Banana POC treatment The parameters observed in this study; Plant height (cm), number of branches (branches), number of pods per sample (fruit), wet weight of production per sample (g), wet weight of production per plot (g), production dry weight per sample (g), and dry weight Production Per Plot (g). The results showed that goat manure had an effect on growth but did not affect the production of peanut plants, liquid organic fertilizer of banana humps had an influence on the growth and production of peanut plants, Combination of goat manure and banana hump liquid organic fertilizer had no significant effect on growth and production of peanut plants.

Abstract

Black corn has its advantage compare to regular corn due to the nutrition component. This could lead the increase of demant to this corn variety. The Effect of providing various biochar sources and various manure on the growthand production of Zea mays black maiz L. The study used factorial randomized block design with two factors, namely the provision of various biochar sources which was combined into several organic fertilizer. Parameters observed were plant height, stem diameter, number of leaves, wet production weight/sample using klobot, wet production weight/plot using klobot,wet production weight/sample without klobot, wet production weight/plot without klobot, dru production weigh of pipil/sample, dry weight of production of onehundred grain pipil. The results of the study showed that the effect of giving various biochar of rice husk corn cobs of candlenut shells did not signficantly affect all observation parameters and various manure, namely cows, chickens and goats also did not significantly affect all observed parameters.

Abstract

The purpose of this study was to determine the feasibility of development of patchouli oil And to identify factors - factors that affect demand for patchouli oil. The sampling method used is a census that is all patchouli oil farmers owning patchouli oil fields and refining. Data Analysis Method used is Cost Analysis.The results showed that the location of patchouli oil refining research effort by the farmers financially feasible to be developed because Value B / C ratio for patchouli oil refining business is 2.28 where the B / C 1, the average profit earned patchouli oil farmers is Rp 45,115,675 / growing season, NPV for patchouli oil refining business is Rp 41,390,526 with interest rate loan or business credit (KUR) is 9% and an initial investment of Rp 19,774,458. Factors that influence patchouli oil are patchouli oil prices and income of patchouli oil farmers but the factors that have a significant effect on patchouli oil production are income, while oil prices have no significant effect on patchouli oil production.

Abstract

Oyster mushroom is one of the most popular consumed mushrooms and also gives benefit for the body because it contains high nutrition and low fat. The goal of this research was to know and analyse the increase growth of some varieties of oyster mushroom on the bagasse media by adding molasses and tofu dregs. The research method was completely factorial randomized design (RAL Factorial) with two factors. The first factor was the media composition of sawdust and bagasse powder and The second factor was oyster musroom. The data analysis was tested by Anova and continued with duncan test if the results of variance were significantly different to very real. The results showed that the best treatment for mycelium growth on M1 media (100% bagasse + 1% molasses + 6% tofu dregs) with the best combination M2V3 (75% bagasse + 25% sawdust + 1% molasses + tofu dregs 6% on brown oyster mushroom). The largest stem diameter for V1 (white oyster mushroom) was 9.24 cm at the first harvest, and 9.01 cm the second harvest. The best length of the stalk in V3 variety (brown oyster mushroom) was 4.94 cm at the first harvest and 5.11 cm the second harvest. The best treatment on oyster mushroom production showed that variety V1 (white oyster mushroom) showed high production at the first harvest 130.25 grams and the second harvest 132.83 grams.

Abstract

To improve the quality of pepper products through organic cultivation using organic growth regulators. This Research aims to investigate concentration and long immersion effect of golden snail meat (Pomacea canaliculata L.) on the growth of pepper cuttings (Piper nigrum L.). the method was experimental with a randomized block design (RAK) Factorial design with two factors namely various golden snail meat concentrations and long immersion ranging from several hours. The parameters observed in this study was Growth Percentage (%), Bud Height (cm), Number of Leaves (Strands), Root Length (cm), and Root Volume (ml). The results showed that the treatment of snail meat zpt concentration did not significantly affect the shoot height parameters but significantly affected the percentage of growth, number of leaves, root length and root volume where the effective zpt concentration was 50%. The long immersion treatment significantly affected the percentage of growth and shoot height where the best treatment at w1 was 3 hours’ immersion. The treatment combination of ZPT golden snail meat (Pomacea canaliculata L.) and long immersion did not significantly affect all observations parameters.

Abstract

This study aims to determine the level of beef demand, the factors that affect beef demand and measure and identify the role of the elasticity of factors that affect beef demand. Sampling is done by simple random sampling. The data analysis method used is qualitative (descriptive) and quantitative analysis. The results showed that the demand for beef at the household level in Sei Sikambing B village, the average beef consumption was 2.2 kg / month. Simultaneously the test results show that the variable beef prices, fish prices, chicken meat prices, egg prices, the level of household income, the number of family members, and taste have a real impact on the amount of beef demand at a 95% confidence level. On the price of partial fish, the price of chicken cuts, the level of household income and tastes significantly influence the demand for beef at a 95% confidence level, while the variable beef prices, egg prices, and the number of family members do not significantly influence the demand for beef meat at the level 95% confidence. From the estimation that the determination value (R2) of 67.8% variation of the seven variables can explain the amount of beef demand, while the remaining 32.2% is influenced by other variables. Beef demand is not elastic to changes in beef prices.Keywords: Demand, Elasticity, Price, Beef, Income
