Residents of agrarian areas are residents who depend their livelihood to agricultural products, but the production of community plantations is often not as desired. Our research aims to know influence the physiological response of weeds to glyphosate herbicide and paraquat herbicide. This experiment was conducted at the UGL Kutacane Faculty of Agriculture experimental garden, Babussalam Subdistrict, Southeast Aceh Regency, which ran from January to February 2018. This study used a non-factorial Randomized Block Design (RBD) consisting of 4 treatment levels: H1: Glyphosate Herbicide = 300 ml/4 L water; H2: Glyphosate herbicide = 1000 ml/13 L water; H3: Herbicide Paraquat = 300 ml/4 L water; H4: Herbicide Paraquat = 1000 ml/13 L of water. The results of Glyphosate Herbicide 1000 ml / 13 L of water effectively control total weeds up to 14 HSA. Glyphosate herbicide is able to inhibit the 5-enolpiruvil-shikimat-3-phosphate synthase (EPSPS) enzyme which plays a role in the formation of aromatic amino acids. The author concludes that the recommended dose of glyphosate based on the research is 1000 ml/13 L of water, because the dose is herbicide Glyphosate has been able to suppress total weed growth.

The study aimed to evaluate the administration of L acidophilus in fermented feed to improve the quality of broiler chicken meat (Protein, Cholesterol) which was maintained for 35 days. The material used is 100 chickens that are 1 day old (DOC). The experiment used a laboratory experimental method with a non-factorial Completely Randomized Design with a treatment level consisting of feed type Ro = standard feed, R1 = R0 + Fermented corn husk 10%, R2 = R0 + Fermentation of 20% corn husk, R3 = R1 + L acidophilus 2% and R4 = R2 + L acidophilus 2%. Each treatment was repeated 4 times and each replication contained 5 chickens. The results of analysis of variance showed that administration of L acidophilus in fermented feed significantly affected the increase in protein (R1) and decreased cholesterol (R3) with an alpha level of 5%. The average protein content R1 = 21.8000 was not significantly different from R4 = 21.5500, while R2 = 21.0500 was significantly different from R3 = 20.6500 and R0 = 20.2000. The lowest average cholesterol level is found in R3 = 64,000 and the highest at R0 = 96,500. While the cholesterol levels R1, R2, R3 and R4 were not significantly different, but were significantly different from R0.

PERFORMANCE OF RED CHILI PEPPER IN NORTH SUMATERA CASE: BERINGIN DISTRIC, DELI SERDANG REGENCY Nasution, Amelira Haris

Publisher : Universitas Djuanda

Red chili pepper is an important commodity for the people of Indonesia. Therefore the government has set red chili pepper as a strategic commodity with a production target of 2.29 million tons in 2019. One of the centers of red chili pepper production is North Sumatera. As a production center, the problem is usually about the low prices at the farm level. This is due to the lack of a marketing channel role analysis that could accommodate farmers' aspirations, causing farmers to not have bargaining power, so farmers are only a "price taker”. The purpose of this study is to analyze the red chili pepper marketing system through marketing channel analysis, marketing channel role analysis and operational efficiency analysis through marketing margins and farmer shares. This study was conducted from June 2019 until August 2019 in Beringin District, Deli Serdang Regency, North Sumatra. Farmers were selected using purposive sampling methods, and middlemen were chosen by using the snowball sampling method. In processing data this study uses descriptive qualitative and quantitative analysis. The results showed that there were 3 channels in marketing red chili pepper. Based on the results of the efficiency analysis it was found that marketing channel 2 was the most efficient channel due to several things, such as the existence of cooperation with the collector and the unavailability of other marketing institutions that favored the red chili pepper farmers. In order to improve bargaining power, farmers need to strengthen the existing STA to be able to reach all red chili farmers.

Usually, commodities shift occurs from food crops to commercial crops, such as horticulture with the aim of improving the welfare of farmer’s life. However, a different situation happened in Sedong Subdistrict, Cirebon Regency where mango farmers switched to paddy cultivation which is a non commercial crop. Most mango farmers began to abandon mango cultivation and made paddy cultivation as their main livelihood. Therefore this research aimed at analyzing the factors underlying the farmer’s decisions to abandon or continue mango cultivation and describing the potential and constraints of mango cultivation. Samples taken were 65 farmers in Sedong Subdistrict, Cirebon Regency consisting of 30 present-grower of mango who also experienced paddy cultivation and 35 past-grower of mango who switched to paddy cultivation. The research method used is the survey research method with data analysis using descriptive statistics and crosstabulation analysis with the fisher exact test. The results showed that the factors related to the farmer's decision to abandon or continue mango cultivation consisted of age, farmer's perception of mango cultivation, risk taking attitude, land tenure status, land area, and farmer group membership. Mango farming has easy transportation in the marketing activities provided by traders, as well as ease of access to credit bunt only for large scale farmers. The constraints felt by farmers in conducting mango farming consist of limited capital for small farmers,

Nutritional composition of large red beans (Phaseolus vulgaris L.) is good for health, much in demand by people for daily cooking, as raw material for making “dodol” or baby food, but production tends to decrease due to land conversion or soil degradation due to inorganic fertilization over do it. On the other hand, population growth continues to increase, demanding higher production. Fertilization of chicken manure can be expected to improve physical, chemical, and biological soil properties so that productivity increases.The study was conducted in the Tanjungsari SMK-PPN Field, Tanjungsari District, Sumedang Regency with a height of 850 m above sea level, Andisol soil order and type of rainfall C. The experiment was conducted from June to August 2018. The purpose of this study was to study the effect of chiken manure dosage on growth and yield of large red bean plants. The research method was a field experiment using a Randomized BlockDesign. The treatment in the form of dung manure consists of 5 levels (0, 10, 20, 30, and 40 tons ha-1) which are repeated five times.The experimental results show that the dose of chicken manure influences the plant height of 6 MST, number of leaves per plant 4 MST and 6 MST, number of pods per plant, number of seeds per plant, weight of wet seeds per plant, weight of dried seeds per plant, weight of 100 grains , and dry seed weight per plot, but no effect on other observations. The dosage of 40 tons ha-1 chicken manure gives the best dry beans weight per bean per plot even though it is not significantly different from the 30 tons ha-1 fertilizing chicken coop.
