Increase Banana Production with Various Applications of Organic Fertilizers I Nyoman Sunarta; Ni Made Trigunasih
Advances in Tropical Biodiversity and Environmental Sciences Vol 1 No 1 (2017): ATBES
Publisher : Institute for Research and Community Services Udayana University

Banana is a fruit that must be present in every activity of the Balinese people. Almost in every cultural and religious activity it is compulsory to present the banana fruit, even more Bali as a tourism area really need fruits including bananas. Therefore the need of bananas is highly demanded in traditional markets or supermarkets in Bali. Until now, the banana production in Bali is far below demand, therefore we still import form places outside of Bali. Banana has a high nutrient value due to nutrients found in it such as potassium and folic acid that is needed by the body. It is also a good so urce of calcium, phosphor, nitrogen, and vitamins such as vitamin A, vitamin C, and B complexes which helps to repair and regenerate tissues of the body. Banana plants can grow in many places, from low grounds until highlands and in various types of soil. Nevertheless for the optimal growth; fertile soil, crumbly thick, lots of humus, aeration, and a good drainage as well as enough water is all needed. By optimizing land use, banana plants are often planted as a sideline plant for plantatio n of coconut, cocoa, and coffee, as well as sideline plants for many other in-between plantations. The way of planting the banana is a conventional method that is commonly used by local farmers including those in the Angkah village. For growth of banana plants we must consider and ensure before planting a crumbly soil when it is solid, to make drainage, and to make levels in slopes. During plantation organic/compost fertilizers is needed as much as 15-20 kg for each hole for plantation. Organic fertilizers that are added influences the good production for both quantity and quality which makes the fruit tastier and has a higher nutritional value. There are some types of organic fertilizers that are used in this research that are: cow waste organic fertilizer, chicken waste organic fertilizer, pig waste organic fertilizer, goat waste organic fertilizer, and compost fertilizer with a dosage of 15 kg per plant. The placement of fertilizers for each places of treatment is conducted b y using a Random Group Design (RGD). The total treatments are 6 and are repeated 3 times. Planting is conduct ed on the 7th of July 2016 with a ground hole size of 60cmx60cm and a depth of 50 cm. The seedlings that are used are decedents that are 50-65cm in height. The specific aim that is wished to be achieved is the increase production of banana as sustainable food in Indonesia. The result up to the progress of this research was found that treatment with chicken waste fertilizer has given the best influence for growth of the banana plant, increased number of leaves, as well as increased height of the plants, all compared to the controlled. The increment of banana plant with chicken waste fertilizer was 63.33 cm for 3 months.Keywords: Banana, Nutritional Values, Production, Organic Fertilizer

Denpasar City is the capital city of Bali Province with a recorded population of 739,000 people in 2010. In 2020, the population will increase to 962,900 people, with a population increase of 1.01% per year.increase in population will have an impact on increasing the Impervious Surface Area (ISA) or watertight artificial structures, for example the area of built-up land. This land use change affects the green land cover in the Denpasar City area, so it is necessary to analyze land use changes in 2010 and 2020 using the Normalize Difference Vegetation Index. In 2010, the land cover for very dense class was 1795.43 ha, with dense land cover 2672, 85 ha, moderately dense 3520.59 ha, not dense 3749.36 ha and no vegetation 784.79 ha. In 2020, the land cover for very dense class is 1708.26 ha, with dense land cover 2287.99 ha, moderately dese class is 3326.15 ha, not dense 4519.29 ha and no vegetation 682.08 ha. The results of the NDVI analysis showed the highest land cover increase, namely the not dense class is 769.93 ha with the dominant land cover being residential or built-up land. This land use change occurs due to the increasing population of Denpasar City.

Induced mutagenesis is one way to improve the quality of crops, especially to increase the resistance to pests and diseases. This research aimed to determine colchicine and ethyl methane sulfonate (EMS) mutagenesis on cowpea M3 purple and mung bean Vima1, in concatenation for developing resistant crops. This research consists of four packages: (1) first package (cowpea M3 purple seeds treated with colchicine solution, (2) second package (cowpea M3 purple seeds treated with EMS solution), (3) third package (mung bean Vima1 seeds treated with colchicine solution) and (4) fourth package (mung bean Vima1 seeds treated with EMS solution). The results of this research revealed that induced mutagenesis by colchicine solution treatment reduced the incidence of bean leaf beetles up to 19% on cowpea M3 purple, as well leaf miners by 5% to 9% and bean leaf beetles up to 5% on mung bean Vima1. Treatment of EMS solution decreased the incidence of bean leaf beetles by 17% on cowpea M3 purple and pink mealybug by 5% to 15% on mung bean Vima1. Induced mutagenesis using EMS solution significantly decreased vegetable leaf miner incidence by 33% to 93% or 71% on average. Colchicine and EMS solution treatment caused aphid attacks in cowpea M3 purple, particularly in pods. The attacks did not happen on leaves and aphid incidence in pods was slower than in control. Some promising mutant candidates were found from this research that will be used in further crop development studies. It is expected that the method and results of this research could inspire faster development of resistant crops.

Analysis Priority Factor of Water Catchment Area in Denpasar City Bali Province Denpasar City as the capital city and one of the tourism centers in Bali Province is experiencing an increasing need for residential land use, because Denpasar City has a fairly large population. This causes a reduction in the water catchment area, so that most of the water becomes runoff. Determination of water catchment areas in all areas using the same factors, namely, soil type, rainfall, slope, and land use. However, each factor will be influenced by environmental conditions which cause each factor to have a different priority value. Therefore, it is necessary to study the priority factors of water catchment areas in Denpasar City. This research was conducted from September to December 2021. The purpose of this study was to determine the determinants of water catchment areas in Denpasar City and the priority value of each factor. This study utilizes spatial technology, namely Geographic Information Systems (GIS) which uses the Spatial Multi Criteria Evaluation (SMCE) to determine the weight and priority value of the determinants of water catchment areas. This research produces an output in the form of a map of each of the determinants of water catchment areas. The results showed that the soil type factor became the first priority, the rainfall factor became the second priority, the land use factor became the third priority, and the slope factor became the last priority.
