Abstract

The social demand for vegetables including beans as a source of vegetable protein increased in line with population growth increased from moment to moment. Fulfillment of its increasing demand has become a problem, especially in the fulfillment of the food with total area of cultivation is increasingly limited, so it is necessary to study the cultivation of an effort to improve productivity and product quality improvement vegetable beans. The study focused on the assessment of NPK fertilizer on some level / dose, which aims to determine the effectiveness of the fertilizer on the productivity of bean plants are maximized. The study was conducted in the village of Lateri for 3 months. Initial studies have shown that the degree of soil fertility in the study site varies because it is close to the river flow, the farther away from the riverbanks degrees diminishing soil fertility. Therefore, the design used was a randomized block design block (RAB) with 5 concentrations (levels) treatment that NPK0 (without fertilizer), NPK1 (5 g / m2), NPK2 (10 g / m2), NPK3 (15 g / m2 ), and NPK4 (20 g / m2). Each treatment was replicated in 4 blocks / different beds, in order to obtain 20 units of trial. Parameter productivity observed is, the diameter of the pod, pod length, pod weight and weight of pods in each bed. The results showed that the level NPK2 provide maximum results, namely: the average pod length = 16.8 cm, diameter pod average = 9.9 mm, weight of pods with an average of 44.6 grams. While ditches or block I pods produce an average weight of 0.41 kg maximum. The LSD with NPK2 level is an application of fertilizer most effectively to improve the productivity of bean plants.

Abstract

Environment, especially in urban areas or places where people do their activities need to kept safe and comfortable for the survival of people who move in it. The Pattimura University campus which currently holds about 20.444 students requires environment that remain comfortable and beautiful to be occupied by academicians, educators and students. Green Campus strategies should be developed by analyzing the factors that influence both internal and external. By using SWOT analysis, results of the research show that the index factor was 0.51 strengths and weaknesses, and opportunities and threats factor index is 0.68, which means that this university in aggressive position: strengths can eliminate weaknesses and opportunities will minimize the threat. Determining the optimal strategy is calculated by using QSPM. S- O strategy is to create an academic community participation and education personnel organized through the green campus-based activities with TAS value = 6,32. W-O strategy is green campus of the application of the policy through media relations and NGOs with TAS value = 6,58. S-T strategy is to make rules and guidelines for the campus management with the concept of a green campus, TAS value = 6,31. W-T strategy is carry out research on the campus environmentally sustainable with TAS value = 6,11.

Abstract

This research was conducted in Pelita Jaya Village, Pohon Batu Hamlet, West Seram Regency from June to July 2022. The research was conducted to study the effect of the interaction of doses of organic fertilizer from pearl oyster biofouling waste and intervals of water administration on the growth and yield of mustard plants. The design used in this study was a factorial randomized group trial design (RAK) with two treatments as follows: Factor I: Pearl Oyster Biofouling Waste Fertilizer (L) with 4 levels, namely L0 = Control, L1 = Dosage of 50 gr/tan, L = 100 g/tan and L3 = 150 gr/tan Factor II : Watering Time Interval (W) namely W1 = 1 day, W2 = 2 days and W3 = 3 days. Each treatment was combined to obtain 12 treatments with 3 replications, resulting in 36 experimental plots. In each plot, 4 sample plants were taken so that in total there were 144 sample plants. The results of this study indicate that the interaction of organic fertilizer from pearl oyster biofouling waste with intervals of watering has a very significant effect on the growth and yield of mustard plants (number of leaves, leaf area, plant fresh weight and plant dry weight). The best treatment interaction was the combined dose of pearl oyster biofouling waste fertilizer 150 g/tan with an interval of watering once every three days for mustard greens (Brassica juncea L.)

Abstract

Fertilizer is the main source of nutrients for plants in relation to growth, development and production processes every day. Manure is a waste product from pets that can be used to improve soil fertility, soil biology and soil physical properties. This study aims to determine the effect of cow manure on the growth and production of lettuce plants (Lactuca sativa L.). The experimental design used was a single-factor complete randomized design (RAL), namely the dose of cow manure. There are 5 types of cow manure treatments, namely S0 (control), S1 (600 grams / polybag), S2 (700 grams / polybag), S3 (800 grams / polybag), S4 (900 grams / polybag). The analysis used is variety analysis (anova) based on observed variables. If there is a real effect, it is followed by the smallest real difference test (BNT) level of 5%. The results of variety analysis and average difference tests show that the use of cow manure with various treatments has a very real effect on plant height, leaf area, header weight, root weight and has a real influence on the number of leaves. The dose of cow manure 600 grams / polybag can increase plant height growth, leaf area and fresh weight of plants.
