Abstract

Effect of Plant Media Composition on Growth and Yields of Pakcoy (Brassica chinensis L.) The high rate of population growth in Indonesia has had a significant impact on total consumption and food needs. The increasing number of population also increases the need for food, however the high demand for food has not been supported by the relatively low level of food production. Planting in polybags is an alternative that can be developed in urban communities by utilizing as little land as possible to continue to be able to carry out cultivation activities so that an urban household is able to meet its own food needs. Pakcoy is one of type of vegetable that has commercial value and is popular with the public because it tastes delicious, crispy, and fresh. The potential for production and market demand for this vegetable is very large, so it needs to be utilized and managed properly and environmentally friendly, but the planting medium often occurs and plants often die due to the composition of the planting medium that does not match the plant's needs. This study aims to obtain the composition of the planting media that can provide the highest yields on the growth of Pakcoy. This study used a randomized block design (RAK) with 7 treatments for the composition of the planting media and 4 replications. The treatment level consists of KA0 (100% soil), KA1 (90% soil + 5% compost + 5% charcoal), KA2 (80% soil + 10% compost + 10% charcoal), KA3 (70% soil + 20% compost + 10% charcoal), KA4 (60% soil + 30% compost + 10% charcoal), KA5 (50% soil + 30% compost + 20% charcoal), KA6 (40% soil + 40% compost + 20 % charcoal). The results showed that the composition of the planting media significantly affected plant height and number of leaves age 21, leaf area, stem diameter, fresh weight total of the plant and dry weight total of the plant. The KA6 media treatment (40% soil + 40% compost + 20% charcoal) reaches 13.60% increase in plant height at age 21, number of leaves age 21 (14,28%), leaf area (59,74%), stem diameter (16,08%), fresh weight total (50%), dry weight total (89,56%) compared to KA0 (100% soil).

Abstract

The Effect of Spacing and Mulching of Rice Straw on Growth and Yield of Corn (Zea mays L.) Corn is the second staple food after rice in Indonesia. Corn as an energy source has advantages compared to other feed ingredients. This research aims to determine the effect of spacing and mulching of rice straw on the growth and yield of corn. This study used a randomized block design (RAK) with the allocation of factorial treatment. The treatment used consisted of 2 factors. (J1) spacing of 50 cm x 50 cm, (J2) spacing of 75 cm x 25 cm, (M0) straw mulch 0 tons/ha, (M1) straw mulch 10 tons / ha, (M2) straw mulch 20 tons/ha. Combination treatments obtained 6 treatments namely; M0 J1, M0 J2, M1 J1, M1 J2, M2 J1 and M2 J2. Each combination treatment was repeated 4 times, so there were 24 study plots. The treatment of spacing significantly affected the weight of dry seeds/m2, very significant on the number of fobs/m2, LAI (Leaf Area Index), fresh weed weight/m2 aged 8 and 12 mst. The spacing of 75 cm x 25 cm resulted in the weight of dry seeds/m2, which was 1.04 kg, which was 20% higher than the spacing of 50 cm x 50 cm 0.83 kg. Rice straw mulch treatment had a significant to very significant effect on the observed variables except 10 mst soil water content, leaf/plant chlorophyll content, number of cobs/m2, and ear diameter. Giving rice straw mulch 20 tons/ha resulted in dry seed weight/m2, which was 1.07 kg 33% higher than without mulch 0.72 kg. The interaction of plant spacing with rice straw mulch has a significant effect on LAI and is very significant on the weight of fresh weed/m2 ages 8 and 12 mst. The interaction of 50 cm x 50 cm spacing with 20 tons/ha rice straw mulch obtained the best results but was not significantly different from the treatment of 75 cm x 25 cm with 20 tons/ha of rice straw mulch.

Abstract

Effect of Application of Potassium Permanganate (KMnO4) on the Shelf Life of Kepok Banana Fruit (Musa paradisiaca formatypical ABB Group) Banana is one of the fruit that is widely cultivated in Indonesia. The potential of large banana production is quite prospective to be developed as a local food source. This research aims to determine the effect of application of potassium permanganate on the shelf life of kepok banana fruit. Research conducted in Agronomy and Horticultural Laboratories and Ecophysiology Laboratory of the Faculty of Agriculture, Udayana University. The research was conducted in June-October 2019. The research was designed by randomized complete block design (RCBD) single factor consisting of 6 treatments i.e. K0 = control (without oxidizing materials), K1 = 10 g oxidizing materials, K2 = 30 g oxidizing materials, K3 = 50 g oxidizing materials, K4 = 70 g oxidizing materials, K5 = 90 g oxidizing materials. The observation is done in a destructive manner (content of vitamin C, total dissolved solids, and hardness) and non destructive (shelf life, weight shrinkage, respiration, color). The results showed that the longest shelf life of the fruit (27 days of storage) was on the K1 (10 g oxidizing materials) and K2 (30 g oxidizing materials) treatment. The smallest weight in the treatment of K1 (10 g Oxidizing materials) and K2 (30 g Oxidizing materials) on the 21st day reaches 0,006% and 0,007%. K2 treatment indicates the lowest respiration rate rate at 9 after treatment (AT) is 4,90 mg CO2/kg/hr. KMnO4 treatment does not give real influence on the hardness, content of vitamin C, PTT except on 21 AT, and the skin color of the fruit except on 27 AT.

Abstract

Evaluation of Soil Fertility Status at the Yeh Ho watershed of Tabanan Regency Based on Geographic Information Systems to Determine Land Management This study aims to determine the status of soil fertility in the Yeh Ho waterahed, Tabanan Regency and to determine the limiting factors for soil fertility in the Yeh Ho Watershed, Tabanan Regency. Provide fertilization directions based on the results of evaluation of soil fertility status in the Yeh Ho Watershed, Tabanan Regency and provide information in the form of a map of soil fertility status based on a geographic information system. The method used in taking soil samples in the study area is the field survey method by first making homogeneous land units obtained through overlaying several thematic maps such as soil type maps, slope class maps and land use maps then each land unit is sampled purposively. sample which is then composited. Soil samples that have been obtained are then analyzed in the laboratory for soil chemical properties including, Cation Exchange Capacity (CEC), Base Saturation (BS), C-Organic Soil, P-Total, K-Total, pH. The results of the analysis of soil chemical parameters are then evaluated on the status of soil fertility based on PPT (1995).The results showed that in the Yeh Ho watershed in Tabanan Regency there were three classes of soil fertility status namely high fertility class (T) consisting of 2 namely land units IV and VII (Jatiluwih Village and Rejasa Village), and medium fertility class (S) consisting of 10 namely land units II, III, V, VI, VIII, IX, X, XI, XII and XIII (Jatiluwih Village, Penatahan Village, Wangaya Gede Village, Tangguntiti Village, Senganan Village and Dalang Village), while those with low fertility classes include 1 land unit, namely I (Desa Beraban). Two soil fertility parameters which are limiting factors are the low P-total and K-total values. Alternative management measures to overcome these two limiting factors are the addition of phosphorus fertilizer, potassium fertilizer and organic matter.
