      Abstract: Development of a Biofungicide Formula and Its Application in Controlling Fusarium Wilt in Tomato Plants (Solanum lycopersicum L.) Fusarium oxysporum fsp. lycopersici is one of the pathogenic fungi that causes Fusarium wilt disease in tomato plants and is very detrimental in tomato cultivation. Fusarium wilt disease control can be done by using a biofungicide formula that does not damage the environment. Biofungicide is the use of biological agents as active ingredients combined with natural carrier agents to form a biofungicide formula. The fungus Gliocladium sp. is a biological agent that can be used as an active ingredient in a biofungicide formula. This study aims to test the ability of Gliocladium sp. in inhibiting the growth of the fungus F. oxysporum fsp. licopersici in vitro and tested the ability of the formula with the active ingredient Gliocladium sp. in suppressing the incidence of wilt disease in vivo. The results of the inhibitory test of Gliocladium sp. against the growth of the fungus F.oxysporum fsp. lycopersici showed that the treatment of Gliocladium sp. can suppress the growth of fungal colonies F. oxysporum fsp. lycopersici with the percentage of inhibition of 99.21%. Testing of biofungicide formulas in vivo shows that the four biofungicide formulas namely F1, F2, F3 and F4 are able to control Fusarium wilt disease in tomato plants with a wilt disease percentage of 0%.

      Abstract: Testing Indigenous Endophytic Bacteria in Controlling Causes of Cacao Rot Disease (Phytophthora palmivora Butler) In Vitro Phytophthora palmivora is the cause of important diseases in cacao, including pod rot. Fruit rot is the most dominant disease because it causes great losses. The use of biological agents is an environmentally friendly way to treat rot disease. One of these biological agents is endophytic bacteria in inhibiting the growth of the fungus P. palmivora which causes pod rot disease in cocoa (Theobroma cacao L.). The research was conducted in vitro. The results of the isolation and inhibition test showed that 1 isolat of endophytic bacteria had the best inhibition, namely BC2 isolat which was able to control P. palmivora fungi disease with an inhibitory percentage of 95.47% when compared to the control at 5 days after inoculation. The results of the inhibition test of the bacterial filtrate of BC2 isolat against P. palmivora at a concentration of 50% showed that the bacterial filtrate of BC2 isolates was able to inhibit the growth of P. palmivora fungi with an inhibitory percentage of 99.80% when compared to the control. The results of the inhibition test of BC2 isolat bacteria on P. palmivora fungi biomass showed that BC2 isolat bacteria were able to inhibit the formation of fungi biomass by 72.72% when compared to the control.

      Pages: 466 - 479
      Abstract: Effect of Concentration of Growth Regulating Substances NAA and Types of Organic Fertilizer on Yield of Citronella (Cymbopogon nardus L.) Citronella is widely used in the therapeutic scrub and aromatherapy industry, especially in the Province of Bali. The aromatic oil produced from the citronella plant is used for incense or aromatic candles. The purpose of the study was to determine the effect of growth regulators NAA (Naphthalene acetic acid) and types of organic fertilizers on the yield of citronella plants. The treatment used consisted of two factors: the concentration of the NAA auxin hormone with the concentration of A0 = 0 ppm, A1 = 10 ppm, and A2 = 20 ppm as the first factor. The second factor is the type of fertilizer P0 = soil, P1= vermicompost 50 g and P2 = 100 g fertilizer goat manure. The results showed the interaction between the concentration of auxin NAA with the type of organic fertilizer significantly affected the number of leaves, number of tillers, and the roots fresh weight. Combination treatment A1P2 (10 ppm NAA and 100 g fertilizer goat manure) showed the highest leaf number (64.07), the highest number of tillers (11.29) and the highest fresh weight of roots (44.17 g), compared with A2P1 and A1P0 with the lowest values ''of 7.16, 41.47, and 25.4 g, respectively. NAA auxin treatment singly significant effect on leaf area and fresh weight leaf. NAA concentration of 10 ppm (A1) provides the highest leaf area (70.09 cm2) and fresh root weight (47.77 g), compared to control (A0) with the lowest value of 65.85 cm2 and 33.38 g. Organic fertilizer treatment significantly affected the fresh weight total and dry weight total. Fertilizer goat manure 100 g (P2) produce a total crop fresh weight of 147.57 g and dry weight of 64.28 g, compared to treatment with P0 and P1 with the lowest values 108.43 g and 49.99 g, respectively.

      Abstract: Evaluation of Soil Fertility Status in Subak in South Denpasar District Based on Geographic Information System Soil fertility is the ability of the soil to provide nutrients needed by plants to support their growth and reproduction, fertile soil conditions have water, air and nutrients in a fairly balanced state and are available according to plant needs, both physical, chemical and biological soil. This study aims to determine the fertility status of subak soil, the limiting factors of soil fertility status and provide direction for managing soil fertility in subak in South Denpasar District. This research was conducted using survey methods and soil test methods. Determination of soil chemical properties is matched with the criteria for assessing soil chemical properties and determining soil fertility status includes the results of chemical properties by combining soil fertility parameters according to PPT (1995). The results of the evaluation of soil fertility status in Subak, South Denpasar District can be grouped into 2 fertility statuses, namely medium and high fertility. Subaks classified as having moderate fertility status are Subak Sanur and Subak Sesetan. Meanwhile, subaks classified as having high fertility status are West Intaran Subak, East Intaran Subak, Renon Subak, Sidakarya Subak, Panjer Subak, Kerdung Subak, Kepaon Subak and Cuculan Subak. The limiting factor that makes the soil fertility status moderate in the study area is due to the low P-Total. The recommended management alternative is the addition of P fertilizer and the addition of organic matter so that soil fertility can be well maintained.

      Abstract: Analysis of Water Balance for Irrigation Water Needs in Tukad Buleleng Watershed, Buleleng Regency Population and human activity have increased so that land use changes resulting in the catchment area does not function optimally. Poor watershed function conditions result in water in the dry season becoming scarce. Drought occurs due to upstream imbalance of watersheds that undergo land function, so the water needs for rice fields are not met. The purpose of this study is to analyze the needs of irrigation water. The method used is descriptive quantitative by calculating from the stage of crop water requirement/CWR, farm water requirement/FWR and project water requirement/PWR. The results showed that the highest value of water needs/PWR projects occurred in the planting period I November III during the generative phase of 196,90 liters/second and the lowest occurred in the planting period II in May I during the fertilization and ripening phase 156,40 liters/second.

      Abstract: Evaluation of Land Capability and Direction of Land Use in the Yeh Ho Watershed Tabanan Regency Yeh Ho watershed is a type of continuous river with the characteristics of being able to flow water throughout the year and in its upstream there are still many seasonal cultivation activities and permanent buildings, this can trigger landslides and erosion due to varying slopes and heights. The purpose of this study was to determine the land capability class, land use directions and appropriate management actions so that the watershed function remains sustainable. The methods used are surveys and field observations, and laboratory analysis to measure the parameters of the physical and chemical properties of the soil. Land capability is determined based on the results of soil analysis in the field and laboratory, and the direction of land use is determined based on rainfall, slope and soil type. The results of the study were in the land capability class IIe, IIIe, IVe-s-g, VIe-g. From the results of direction of land use, that the Yeh Ho watershed can be directed to four types of land use, namely annual cultivation, protected areas, buffer areas, and seasonal cultivation because the score for calculating land use directions is in the range of 60-175. The recommended land use as management actions are annual crop cultivation (units 1, 5, 7, and 8), high density mixed gardens (units 2, 3, 11, and 12), high density mixed forest gardens (units 4, 9, and 10), area annual crop cultivation (units 6 and 13).

      Abstract: Isolation and Degradation Test of Cellulolytic Bacteria from Organic Waste at TPST-3R Kertalangu and TPST-3R Nangun Resik Against Jepun Bali Flowers Cellulolytic bacteria are microorganisms that produce cellulase enzymes that can synergistically hydrolyze crystalline cellulose into smaller oligosaccharides and eventually become glucose which can be used by these microorganisms as a source of nutrients for their growth. Cellulose acts as an inducer in cellulase synthesis which has two functions, namely as an inducer in enzyme synthesis and as a carbon source for cell growth. This study aims to obtain bacteria that are able to degrade organic waste samples using several methods, namely bacterial isolation, selective media, identification of bacterial colony morphology and qualitative bacterial degradation test. The results of this study indicated the presence of bacterial growth in selective CMC media and showed the ability of bacteria to degrade organic waste samples on Gelatine media. The results of bacterial isolation on CMC media with a dilution level of 10-8 were found 14 bacterial isolates in the TPST-3R Kertalangu sample and 16 bacterial isolates in the TPST-3R Nangun Resik sample. Each isolate was classified based on colony morphology, obtained three different isolates. Isolates taken from TPS Kertalangu were coded A, B, and C while isolates taken from TPST-3R Nangun Resik were coded E, F, and G. Most of the surface is convex, and flat. Based on the results of the calculation of the cellulolytic index, it was found that only isolate G was in the medium category and the other isolates had a high category value. The formation of a clear zone around the colonies that grew on CMC media showed that the isolate had cellulolytic activity measured qualitatively. The results of the analysis of the degradation ability of the Bali Jepun flower samples showed that isolate F was the fastest degraded isolate with an average of 3.5 days.

      Abstract: The Agronomic Performance and Resistance on Several Hight Yielding Varieties  (Oryza sativa L.) to Bacterial Lesf Blight (Xanthomonas oryzae pv. oryzae) In Bali  Province, Indonesia The purpose of the test was to determine the level of bacterial leaf blight (BLB) in several high yielding varieties to obtain resistant varieties to replace Ciherang. The study was carried out by cultivating several high-yielding rice varieties in rice fields in Subak Dlod Sema, Badung from January to May 2020.  The appropriate design was a 1-factor randomized block design with 5 treatments and was repeated 5 times. The superior varieties planted were Inpari 19, Inpari 40, Inpari blast, Situ Bagendit and Ciherang varieties for comparison. The incidence and severity of BLB were assesed in the field using the diagonal random sampling method by measuring the lenght of the lesions on the  leaves.  Measurement of plant samples as many as 10 clumps on a natural plot measuring 400 m2 diagonally. Measurement of BLB disease attack is carried out every 2 weeks starting from the age of the plant 2 weeks after planting (WAP) to 10 WAP. Analysis of the data using Analysis of Variance (ANOVA) and continued by testing the mean value of BNT at 5% level. To see the progression of the severity of BLB disease, it was analyzed by regression. The results of the study showed that 2 of the 4 varieties studied, namely Inpari 40 and Inpari blas were not attacked by BLB disease with an attack of 0.71% each while Inpari 19 and Situ Bagendit were attacked by HDB disease with a mild attack category, namely 2.67% and 2.97% compared to 3.20%. The increasing time of disease progression increased in Inpari 19 and Situ Bagendit with the regression equation y= 0.0464x²+3877x and y = 0.0275x2+0.38x compared to y = 0.0645x²+0.2935x. The higher the number of tillers/clumps, the number of filled grain/panicles and the number of grain/panicles can increase yield production. The production losses of Inpari 40 and Inpari blast were 0.71% each, so it can be said that the introduction of high yielding varieties (HYV) is feasible to be developed as a substitute for Ciherang in the use of resistant varieties to control BLB disease.

      Abstract: The Testing of Several Hight Yielding Varieties (Oryza sativa L.) to The Attack Level of Stem Border tests The purpose of the study was to determine the level of stem borer attack on several high-yielding varieties of rice cultivated in Bali to obtain varieties resistant to stem borer as a substitute for Ciherang.  The study cultivated various superior rice varieties, namely Inpari 19, Inpari 40, Inpari blas, Situ Bagendit, and Ciherang varieties for comparison.  The incidence and severity of stem borer attacks were assessed in the field using the diagonal random sampling method.  The sample measurement of 10 plant clumps was carried out diagonally on the plot area in the form of a natural plot measuring 400 m2.  The appropriate design was 1-factor randomized block design with 5 treatments and 5 replications.  The data collected was related to the percentage of rice stem borer in the vegatative phase 2-6 weeks after planting (WAP) “Sundep” (% dead hearts) and the generative phase 8-10 WAP “beluk” (% white ear heads). The measurenent of the attack level is based on the tehnical instuctions for observing and reporting plant-disturbing organisms and climate change impacts (OPT-DPI) of the Ministry of Agriculture in 2018 as well as the production of tons per hectare. The analysis used a diversity fingerprint (ANOVA) and continued with a different test for the mean value of 5% LSD.  To see the development of the rice stem borer, it was further analyzed by regression analysis.  The results showed that the percentage of stem borer attack on Inpari 40 and Inpari blast varieties was known to be 0% each with a square root value (' (x + 0.5) = 0.71%.  So the Inpari 40 and Inpari blas varieties are candidates for resistant varieties to replace Ciherang. The level of resistance of varieties such as Inpari 19, Sit Bagendit, and Ciherang to stem borer cannot be determined because the attack is still below the economic threshold (<10%).
