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

Effectiveness of Giving Some Herbicides on Weed Growth and Yield of Rice Plants with Direct Seed Sowing System without Ground (TABELATOT) One of the obstacles in rice cultivation is the presence of weeds. Weeds are plants that humans does not want in the located that can reduce agricultural yields. Weed control techniques in rice plants can be done by using herbicides. This study aims to determine the types of weeds that grow in rice cultivation with the tabelatot system for each type of herbicide used, to determine the effectiveness of each type of herbicide used on weed growth and lowland rice yield in the tabelatot system, to determine the type of herbicide. which one can increase the growth and yield of rice in a tabelatot planting system. This study used a randomized block design (RBD) with 4 treatments, namely control, logran herbicide, metafuron herbicide and benfuron herbicide. This treatment repeat six times. Based on the statistical results, it was found that the types of weeds that grew in rice cultivation were 2 (two) from grass groups, namely Echinochloa crusgalli (L.) Beauv, and Cynodon dactylon, 1 (one) from the nut group namely Cyperus difformis L, and 4 ( four) from broadleaf groups, among others, Monochria vaginalis (Burm.f.), Ludwigia octovalvis, Spenochlea zeylanica, and Limnocharis flava. The results showed that the herbicide treatment logran, metafuron and benfuron could reduce the weight of wet weeds m-2 at the age of 42 hss, 0.90 kg and 0.92 kg, respectively or decreased by 86%, 57% and 56% compared to the control, namely 2.13 kg and reduced the weight of oven dry weeds as much as 0.01 kg, 0.09 kg and 0.09 kg, respectively or decreased by 95%, 59%, and 59% compared with 0.22 kg without herbicide. he most effective herbicide in controlling weeds in the table cropping system is logran herbicide seen from the parameters of oven dry grain weight ha-1 (ton), the treatment of logran herbicides, metafuron and benfuron can produce weight of 5.31 tons, 5.28 tons respectively. and 5.25 tons or increased significantly by 65%, 64% and 63% compared to the control, namely 3.23 tonnes, the high yield was due to the ability of logran herbicides to suppress weed growth so as to minimize competition between rice and weeds.
