Abstract

The purpose of this study was to study the effect of improved quality of oil palm empty fruit bunch compost on the chemical properties of ultisol soil, growth, production, nutrient content, and heavy metals Pb in mustard plants. This study was conducted from March 2015 to January 2016. The study was conducted with a single factor experiment with 13 treatments and 3 replications, so that 39 unit experiments were obtained which were placed into a Completely Randomized Design. The treatment consisted of 4 tankos compost, namely tankos compost. The beginning of the composting process was added to boiler ash at 4 dosage levels, namely 0% (K1), 15% (K2), 25% (K3), 35% (K4), then given into the soil with 3 dose levels, namely 10 tons/ha (D1), 20 tons/ha (D2), 30 tons/ha (D3). Observational data was analyzed statistically using the Analysis of Variance (ANOVA) with the F test at an alpha level of 5%. If the treatment is found a significant effect, it will be continued with the Duncan Multiple Range Test (DMRT) at the alpha level of 5%. The results showed that the various doses of oil palm empty fruit bunch compost plus added boiler ash at the beginning of the composting process at the same dose had a significant effect on increasing Ca-dd, Mg-dd, K-dd soils and decreasing Al-dd soils, plant height, number of leaves, leaf width and K content of mustard plants. The best dose that can produce the highest production was the composting process treatment that was added with 15% boiler ash at a dose of 10 tons/ha (K1D1). In the Pb heavy metal content was not measurable, so the plant was suitable for consumption.

Abstract

Food availability is food available from natural sources either through food production, cultivating the land, or by other of obtaining food, such as fishing or gathering food. Food availability is important and a priority for food security in Pekanbaru City. The purpose of this research is to map food security based on the aspect of food availability in Pekanbaru City. This research was conducted using the literature study method, used secondary data. Data analysis using FSQ (Food Security Quotient). The results of the study, using calculation of Food Security Quotient (FSQ) in Pekanbaru City, for variables of production and harvested area with a category is very food safe, the commodity is soybeans. Variable food needs, commodities with very safe categories are rice; sweet potato; and peanuts. The aspect of food availability in Pekanbaru City is included in category point V, which is very food safe. The food availability index in Pekanbaru City is a very food-secure condition.

Abstract

The aim of the work was to find out the interaction between pineapple peel bokashi and organic NPK fertilizer and the main effect in increasing the growth and yield of purple eggplant (Solanum melongena L.). The study was conducted at the experimental farm of the Faculty of Agriculture of the Riau Islamic University from February to May 2020. This experimental design was 4 x 4 factorial using a completely randomized design with 3 replications. The first factor was the dose of pineapple peel bokashi consists of 4 levels: 0, 0.75, 1.5, 2.25 kg per plot. The second factor was the dose of NPK organic Fertilizer, consisting of 4 level: 0, 7.5, 15.0, 22, 5 gram per plant. The parameters observed were plant height, flowering age, harvest age, number of fruit crops, weight of fruit per plant, weight of fruit per fruit, number of residual fruits. The data were analyzed statistically and continued with the real difference test (BNJ) at the 5% level. The results showed that the interaction of pineapple peel bokashi and organic NPK had a significant effect to all observation parameters and the best treatment was a combination of pineapple skin bokashi 2.25 kg/plot and NPK organic 22.5 g/plant. The main effect of pineapple peel bokashi dose was significant on all observed parameters with the best treatment was 2.25 kg / plot. The main effect of organic NPK was significant for all parameters. The best treatment was found on organic NPK dose of 22.5 g/plant.

Abstract

This research aimed to find out the interaction and the main effect between Petrobio biofertilizers and NPK Mutiara 16:16:16 fertilizers on the growth and yield of soybean plants. This research was conducted at the experimental farm of Faculty of Agriculture, Riau Islamic University, Pekanbaru from July to October 2019. The design used in the study was a completely randomized design, consisting of 2 factors. The first factor was the dose of Petrobio's Biofertilizer (P), consisting of 4 levels of treatment namely 0, 3, 6, and 9 g per plot. The second factor was NPK Mutiara 16:16:16 (N) fertilizer dosage, consisting of 4 levels, 0, 10, 20, and 30 g per plot. So that the treatment combinations obtained as 16, consisting of 3 replications with a total of 48 experimental units. The observed parameters were plant height, percentage of pods with a healthy crop, crop weight of seeds, the weight of 100 seeds, harvest index, and further tested BNJ at the level of 5%. The results showed that the interaction of Petrobio Biological fertilizers and NPK Mutiara 16:16:16 fertilizers was significant for the percentage of pithed pods, crop seed weight, and harvest index. Effect of application of Petrobio Biofertilizer dosage, 9 g per plot and NPK Mutiara fertilizer 16:16:16 30 g per plot P3N3. The main effect of Petrobio biological fertilizer was evident in plant height, net assimilation rate, relative growth rate, and weight of 100 seeds. The best treatment is on Petrobio 9 g per fertilizer plot. The main effect of NPK Mutiara 16:16:16 fertilizer was found in all observed parameters. The best NPK Mutiara 16:16:16 fertilizer treatment was at a dose of 30 g per plot.
