Kepok banana is quite widely used in Pekanbaru because this banana is one of the main ingredients in making typical Riau Pekanbaru food souvenirs. Therefore, the waste of banana peel produced is very high. If left unchecked, it will have a negative impact on the surrounding environment. Based on this, the solution may be processing banana peels as LOF (Liquid Organic Fertilizer). The purpose of this study was to determine the effect of liquid organic fertilizer from kepok banana peels and TSP on the growth and production of peanut plants. This study used a factorial completely randomized design (CRD) with 3 replications. The first factor was the concentration of LOF kepok banana peels, consisting of 4 levels, 10, 20, and 30 ml/l of water, and the second factor was the dose of TSP fertilizer, consisting of 4 levels, are 0, 6, 12, and 18 g/plot. The parameters observed were plant height, appropriate growth rate, net assimilation rate, pod dry weight per plant, the weight of 100 seeds, and harvest index. The data were analyzed by ANOVA with the BNJ further tested at the 5% level. The results showed that the interaction of kepok banana peel POC treatment and TSP significantly affected all parameters and increased the growth and production of peanuts. The results with the best treatment combination were 30 ml/l of POC Kepok banana peels concentration and 18 g/plot of TSP dose.

This study aimed to determine the effect of spraying time and concentration of paclobutrazol on the growth of tamarind seeds (Albizia saman Jacq). This research has been carried out Experimentally farm of the Faculty of Agriculture at Universitas Islam Riau, Pekanbaru. The research was carried out from June to September 2020. This study used a Factorial Completely Randomized Design (CRD) by using two factors. The first factor was the spraying time (W), consisting of 3 levels, namely: 25, 50, and 75 days after planting (day) and the second one was the concentration of paclobutrazol (K), consisting of 4 levels, namely: 0, 75, 150, and 225 ppm to obtain 12 treatment combinations with 3 replications, with the total of 36 experimental units. Each unit consisted of 4 plants per plot and 2 were observed as the samples for a total of 144 plants. The Parameters measured were plant height, stem diameter, number of branches, number of leaves, and leaf area. The data were statistically analyzed and presented with the Honest Significant Difference Test (HSD) at the 0.05 level. The results showed that the effect of time and concentration of paclobutrazol was significant on plant height, stem diameter, number of branches, and leaf area. The best treatment was a spraying time of 50 days (W2) and 150 ppm of paclobutrazol concentration (K2). The main effect of real spraying time was on all observed parameters. The best treatment was 50 days after planting (days) (W2). The main effect of paclobutrazol concentration was significant on all observation parameters. The best treatment was a concentration of 150 ppm (K2).
研究了多效唑喷施时间和浓度对罗望子种子生长的影响。本研究是在北干巴鲁伊斯兰大学农学院的实验农场进行的。该研究于2020年6月至9月进行。本研究采用两因素全随机设计(CRD)。第一个因子为喷施时间(W)，分为3个水平，即播种后25、50、75天(天);第二个因子为多效唑浓度(K)，分为4个水平，即0、75、150、225 ppm，得到12个处理组合，共3个重复，共36个试验单元。每个单元由每块地4株植物组成，其中2株为观察样本，共144株。测量的参数为株高、茎粗、枝数、叶数和叶面积。对数据进行统计学分析，采用诚实显著差异检验(HSD)，水平为0.05。结果表明，多效唑处理时间和浓度对植株高、茎粗、分枝数和叶面积的影响显著。最佳喷施时间为50 d (W2)，多效唑浓度为150 ppm (K2)。实际喷涂时间主要影响各观测参数。最佳处理为种植后50 d(天)(W2)。多效唑浓度对各观察参数均有显著的主效应。最佳处理浓度为150ppm (K2)。

The purpose of this study is to find out what is the biggest motivation of farmers to develop urban farming in Pekanbaru. This study used a survey method. Based on the information of the key respondent, in this case the director of Komunitas Hidroponik Riau, 17 respondents were obtained using the snowball sampling technique. The level of motivation is measured on a Likert scale, and then the highest average score for each indicator is calculated. Based on the research results, it is known that, in general, the motivation level of Pekanbaru farmers in the development of urban agriculture is classified as very good with an average of .53. Financial motivation is the highest, with an average of .76 (very good). These results indicate that economic factors are the strongest motivating factor for the development of urban farming in Pekanbaru.
