Abstract

The study aimed to determine the prevalence of myiasis in buffalo at Moa island. Data collection was carried out from April to December 2020 using a survey method in 3 villages selected by stratified random sampling. Samples of  98 buffaloes were selected using the detect disease method and taken from four villages. The results showed that the prevalence rate of myiasis in buffalo was 7.14% with details of the prevalence at the village level, namely Tounwawan 9%, Nyama 6%, and Klis 4%. Myiasis was founded in adult buffalo and it was caused by the Chrysomya bezziana. The number of flies per site infestation was 11-23 heads with a duration of 3.09-4.17minutes. The favorable site for oviposition were the neck, back, thighs, and vulva. The predisposing factors that caused the injury were headers, bird pecks, and bush punctures. Maggots had burrowed deep inside causing necrotic cavities, malodorous, and reddish-brown fluid.

Abstract

Hydroponics uses water as a growing medium and a source of nutrients for the plant. Water conditions suitable for plant growth have a pH of 5.6-6.5. Water conditions in Pasuruan City tend to be alkaline with pH 8. It is necessary to give an acid solution to reduce the pH value. This research aimed to study the effect of nitric acid, phosphoric acid, and sulfuric acid on fluctuation in the pH of hydroponics. The study used a Randomized Block Design with nine treatments: Kebonsari Village water + nitric acid; Kebonsari Village water  + phosphoric acid; Kebonsari Village water + sulfuric acid; Bugul Kidul Village water + nitric acid; Bugul Kidul Village water + phosphoric acid; Bugul Kidul Village water + sulfuric acid; PDAM water + nitric acid; PDAM water + phosphoric acid; and PDAM water + sulfuric acid. The results showed that the phosphoric acid solution was able to maintain the pH in the optimal range of 6,8 – 7,1 for all types of water, more stable than nitric acid and sulfuric acid solutions. Plants cultivated with PDAM water with phosphoric acid solution showed high leaf chlorophyll content (48,480 mg/L), leaf Nitrogen (4,38%), and plant weight (1.807,00 g).

Abstract

This study aimed to determine the response of lettuce plants to type planting media and watering intervals in the verticulture system. This research method used a split-plot design with eight treatments and three replications, including Main plots P1 (2 days watering interval) and P2 (4 days watering interval). The second treatment as sub-plots consisted of planting media: M1 (soil: manure), M2 (manure: sand), M3 (manure: husk charcoal), and M4 (soil: manure: husk charcoal). Observations included growth parameters (plant height, number of leaves, leaf area) and harvest parameters (total fresh weight of plants, fresh weight of roots, total dry weight of plants, dry weight of plants without roots, dry weight of roots). The result of the 2nd watering interval was able to significantly increase the growth component and fragrant lettuce plants compared to the 4th watering interval. Different types of planting media showed a significant effect on plant height but did not affect the number of leaves, leaf area, and components of the yield of fragrant lettuce.

Abstract

The general problem of organic vegetable farming is the cultivation technique which must have organic principles, both in the use of inputs and cultivation techniques. In addition, the market for organic products is still limited. This study aimed to formulate the best strategy for the Vigur Organic Women's Farmer Group. The research location was determined used purposively and the sample was taken by accidental sampling. The data was analyzed by using a qualitative descriptive method using the SWOT analysis method. The results showed that the Vigur Organic Women Farmer Group was in cell IV of the IE matrix, which means that they were carrying out a growth and development strategy, while the results of the SWOT analysis were in quadrant I (growth) with a value of 2.45 in the internal position, namely strength. The priority of the alternative strategy to be developed based on the results of the QSPM (Quantitative Strategic Planning Matric) analysis is to optimize and increase the volume of organic vegetable production with the highest total attractive value (TAS) of 6.44. The priority of the next alternative strategy is to maintain organic certification of 6.12, and the last alternative strategy carried out by the Vigur Organic Women's Farmer Group is to manage and increase cooperation with distributors with a TAS value of 6.00
