Abstract

Rice is an important crop to provide staple food for majority of Indonesian. Therefore, rice must be produced continuously in sufficient amount to fulfil the need of population food every years. Paddy field is dominan and the number of production is affected by using producton factors (inputs). The purposes of this research are to examine the factors affecting rice production and to calculate cost, production, revenue, profit, and efficiency. The research used survey method and located in Lareh Sago Halaban District, Lima Puluh Kota Regency, Sumatera Barat Province. The research was conducted during 6 (six) months from January to June 2022. A total of 42 samples was selected randomly from 135 farmers’ group from 8 villages. Statistical and mthematics techniques were used to analyze data. Based on statistical analysis by using multiple-regression model of Cobb-dauglas function production, it was found that land area, seeds, labors, urea fertilizer, TSP fertilizer, KCl fertilizer, organic fertilizer, insecticide, herbicide, and fungicide significantly affected rice production. The production costs were an average of IDR 4,732,936.84/cultivated area/growing season with 2,304.29 kg/cultivated area/growing season on average and land area averaged 0.41 ha. The revenue was IDR 10,369,285.71/cuktivated area/growing season and profit was IDR 6,980,657.21/cultivated area/ growing season on average with efficiency value of 1.74.

Abstract

Liquid Organic Fertilizer (POC) has a high amount of nutrients that can be used as a nutrient source for the growth of Chlorella sp. This research aimed to determine the effect of Liquid Organic Fertilizer on the growth and abundance of Chlorella sp. cells and to obtain the optimal dosage of Liquid Organic Fertilizer for the growth of Chlorella sp. This research was conducted at the Laboratory of Microalgae and Fish Nutrition, Faculty of Agriculture, Islamic University of Riau. The research used a Completely Randomized Design (CRD) with four treatments, specifically giving POC doses of 2.5cc, 5cc, 7.5cc, and 10cc/l of water with three repetitions. The measured changer is growth and abundance, biomass, and parameters of the culture media such as temperature, pH, nitrate, and phosphate. The research results obtained the highest abundance of Chlorella sp. cells. amounted to 7,966,667 cells/ml at the POC dose of 5 cc/l of water, and the peak was on the 16th day, the lowest dose of 2.5 cc/l was 6,483,333 cells/ml, cell-specific growth rate Chlorella sp. during the study ranged from 0.074-0.087/hr. The highest amount of biomass was 0.3629 gr/l, parameters of the culture media such as temperature ranged from 26-30oC, pH of 6-8, nitrate 1.976-4.802 mg/l and phosphate 0.360-2.680 mg/l.
