Cocoa pod disease caused by the fungus Phytophthora palmivora has resulted in loss of cacao in Indonesia, especially in Bali. So far the disease control strategy is not fully understood. So there is a need to find an alternative by using endophytic fungi associated with cocoa plant. Endophytic fungi are needed to be explored in all parts of the cocoa plant such as stems, leaves and husks. The prevalence of fungal endophyte was determined by the size of its domination on the surface tissue for protection against pathogen. The exploration of the endophytic fungi benefits is aimed at finding biological agent s that could control of pathogenic P. palmivora. The results showed that 15 types of endophyte fungi have been found in the healthy leaves, stem and pod husks, with the prevalence of fungal endophyte originated from healthy leaf Mecelia sterilia (hyphae sterile) around 30%, the endophyte fungi originated from the healthy cocoa stem are Mycelia sterilia, Neurospora spp and Trichoderma spp around 25%. While the endophytic fungi originated from healthy skin fruit is Trichoderma spp. around 35%. The in vitro test results of endophytic fungi antagonistic against P. palmivora indicated that the endophyte fungi originated from the leaf namely Aspergillus spp was obtained at 80 ± 2%, A. niger 90 ± 2%, A. flavus 100%, and Trichoderma spp. 90 ± 1.5%, the endophytic fungus originated from rods namely Neurospora spp. was 95 ± 2%, and Trichoderma spp. was 90 ± 2%. While the endophytic originated from rind namely Neurospora spp . was 95 ± 1.5 % and Trichoderma spp. was 80 ± 2%. The results of in vivo test of antagonistic endophytic fungi against P. palmivora showed that all of endophytic fungi (Aspergillus sp., A. niger, A. flavus, Neurospora sp., and Trichoderma sp.) have a significant effect in suppressing the growth of mycelium P. palmivora.Keywords: Endophytic Fungus, Phytophthora Palmivora, Inhibition, Prevalence, Biological Agents

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

Meloidogyne spp. Are among the polyphagous pest that has spread around the world and has been reported to attack cultivated plants with economic values. Various ways had been applied to control the Meloidogyne spp. nematodes but has not yet showed any effective results. We are currently using synthetic pesticides because of its fast response and ability to maintain plant productions. The improper application of synthetic nematicides would have a negative impact on the environment. The aim of this research is to know the effectiveness of betel leaf concentration (Piper betel L.) to curb the development of nematodes on Root-Knot Meloidogyne spp and the growth of tomato plants. This is a descriptive research, with the utilization of betel leaf extract (Piper betel L,) by concentration treatment of 0 %, 5 %, 10 %, 15 % and 20%, each of which are repeated five times. Complete Random Sampling (CRS) with the F test is used and continued with the Duncan test at a 5% rate. The result shows that the betel leaf extract of the 20% concentration was the most effective either on the growth of plants and to the root-knot nematodes. The suppression of growth in the ground was 80,06% and the lowest was recorded with the 5% concentration ( 2,32 %); the suppression of root-knot was 45,45 % while the lowest was with the 5% concentration (12,12 %); the suppression of nematodes population in the roots was 45,45% while the lowest was with the 5% concentration (39,76 %); and last was the suppression of egg mass which was 61,73 % while the lowest was shown in the 5% concentration (18,32 %). It can be concluded in this research that the most effective betel leaf extract concentration was at 20%.Keywords: Meloidogyne spp., Piper betel L., CRS

Protection and conservation of marine biodiversity and their utilization based on sustainable environment, balance, and fairness play an important role in the context of sustainable tourism. The importance of protecting the availability of a healthy environment, which not only focuses on the present, but also a sustainable environment for future generations, is regulated under several provisions such as: Law of the Republic of Indonesia Number 27 Year 2007 on the Management of Coastal Areas and Small Islands, Law No. 32 of 2009 on the Environmental Protection and Management, Law No. 10 Year 2009 on Tourism, Law No. 5 Year 1990 on the Conservation of Biological Diversity and Ecosystems, the UN WTO Global Code of Ethics for Tourism, and the Convention on Biological Diversity. In order to protect and conserve marine biodiversity, it is considered relevant to use deep ecology approach in realizing the presence of marine biota and sustainable biodiversity for the entire ecosystem of life, including human life ecosystems in the development of tourism activities. States and all stakeholders have responsibility for the protection and conservation of biodiversity, including sustainable development of marine biota and its diversity for tourism activities.Keywords: Biodiversity, Protection, Conservation, Responsibility, Sustainable Tourism

Research on the effect of dosage combination of Evagrow bio-fertilizer and chemical fertilizers on soil properties, growth and yield of rice has been carried out in the glasshouse, Faculty of Agriculture, Udayana University using factorial experiment with a Randomized Block Design (RBD). The first factor is Evagrow bio-fertilizer in 3 level, i.e. E0 (without bio-fertilizers), E1 (5 g bio-fertilizer/L) E2 (10 grams bio-fertilizer/L). The second factor is chemical fertilizer, which consists of 3 levels: K0 (without chemical fertilizers), K1 (150 kg Urea/ha + 75 kg SP36/ha + 37.5 kg KCl/ha), K2 (300 kg Urea/ha + 150 kg SP36/ha + 75 kg KCl/ha). The results showed that chemical fertilizers give a significant and very significant effect on most of the rice growth and yield parameters. The application of chemical fertilizers K1 and K2 increased yield of dry grain harvest to 52.87% and 102.54% compared to controls. Application of Evagrow bio-fertilizer did not significantly increase growth and yield of rice. There is no interaction between chemical fertilizers and Evagrow bio- fertilizer. Similarly to some of the soil characteristics, biological fertilizer and chemical fertilizer application did not show significant effect on most of the soil characteristics, except on salt levels.Keywords: Evagrow Biofertilizer, Inorganic Fertilizer, Oryza Sativa

The incidence of diseases caused by pathogenic viruses in chili is still a major problem in reducing the production of chili in Indonesia. Most agricultural crops are hosts for one or more types of plant viruses, so the viru s continued to be a problem in the tropics. Virus is passive, requires intermediaries vector to be transmitted to other plants. The goal of this research was to develop control strategies for aphids that act as a viral vector and pest chili plants using plastic mulch. Control design that was developed in this study based on the habits of local farmers, using plastic mulch with two colors, black and silver. Mulching is done to dispel the arrival aphids into the chili crop, at the same time preventing the emergence of weeds that act as alternative hosts of the virus. The use of silver plastic mulch to control vector viral populations was better compared to black plastic mulch during chili planting. The use of silver plastic mulch can improve yields of chili crops.Keywords: Aphid, whiteflies, Chili chili, virus
