Abstract

Legume cover crop (Mucuna bracteata L.) is a creeper which is currently often used to increase soil fertility in plantation areas. This plant is a leguminous plant that can fix nitrogen nutrients in the soil. One of the M.bracteata plant breeding programs to increase diversity is mutation using gamma ray radiation. The research objective was to determine the level of radiosensitivity of legume cover crop using gamma ray irradiation. The research was conducted at PAIR BATAN using a Gamma Chamber 4000A irradiator and in agricultural experiment, Labuhanbatu University. The plant material used was M.bracteata seeds with irradiation doses of 0, 200, 250, 300, 350 and 400 Gy. This study uses a curve fit analysis program to calculate the LD50 value (Lethal dose 50). The results showed that the plant radiosensitivity by calculating the LD50 value of M.bracteata at the age of 2 Weeks After Planting) was 348.737 Gy. The higher the radiation dose given, the lower the percentage of growth. Keywords: diversity; leguminous; lethal dosage; mutation; gamma rays

Abstract

Palm oil midrib can also be used as a base for composting. Palm fronds which have been underutilized by the community and are more wasteful are usually only stacked around the tree. One way to use oil palm leaf fronds as a source of plant nutrients is in the form of compost. Palm oil fronds contain high lignin, so the process of composting oil palm fronds takes a long time. The process of decomposition of oil palm fronds naturally takes a long time which is around 3-4 months. This study will analyze the feasibility of utilizing corn meal as a compost material for oil palm fronds, corn meal is used as an energy source for microorganisms to accelerate the decomposition of oil palm fronds.This research was conducted in the greenhouse of the Agricultural Agribusiness College of Agriculture (STIPAP) Medan. When the research was conducted for 3 months, from March to May 2019. Palm oil fronds composting is 50 kilograms with a production cost of Rp 1,121,308 and a total income of Rp 1,200,000. The net profit of making oil palm frond compost is Rp. 78,692. BEB the price of making palm oil compost is Rp. 22,426 while the selling price of compost is Rp. 24,000. The BEP of producing oil palm fronds compost obtained is 47 kilograms while the amount of production of oil palm frond compost making is 50 kilograms so it can be interpreted that BEP production of oil palm frond composting is profitable because the amount of production of BEP production is greater. R / C ratio, which is the ratio of total receipts with total production costs has an R / C value of 1.07, then the R / C value can be greater than 1, it can be interpreted that the R / C value of making compost makes a profit. B / C ratio, which is the ratio of profits to total production costs has a B / C value of 0.07, thus the B / C value is smaller than 1. Then it can be interpreted that the B / C value of making compost does not benefit or is not feasible to run in the production of 50 kilograms. Keywords: palm fronds, compost, corn meal, break event point
