Abstract

The aim of the study was to determine the effect of liquid organic fertilizer application of palm sap and jackfruit waste on the growth of mustard greens and the optimum dose of LOF on mustard greens. The research was carried out from November 2020 - March 2021 in the yard of the house in Carep Village, Langke Rembong District, Manggarai Regency, East Nusa Tenggara with an altitude of 1,171.5 m above sea level and at the Soil and Environment Laboratory, Faculty of Agriculture, Udayana University. The design used in this study was CRD (Completely Randomized Design) with 6 treatments and 4 replications. The LOF dose treatments P0 = 0 ml/l water, P1 = 5 ml/l water, P2 = 10 ml/l water, P3 = 15 ml/l water, P4 = 20 ml/l water and P5 = 25 ml /l water. Parameters observed were plant height, number of leaves, plant fresh weight and plant dry weight, total number of microorganisms in the soil, pH, organic C, total N, available P, available K and soil moisture content. The results showed that the application of liquid organic fertilizer from jackfruit waste on mustard plants (Brassica juncea L.) had a very significant effect on the parameters of available K, moisture content, total microbial population, plant height 21 DAP, fresh plant weight and oven-dried plant weight, gave a significant effect on the parameters of N-total, plant height 14 DAP and 28 DAP and had no significant effect on organic C, soil acidity (pH), available P, plant height 7 DAP. This study has not found the optimum dose because the highest dose treatment (P5) is still increasing.

Abstract

This study aims to determine the effect of ripening time on the development of tomato seed quality. The experiment used was a Completely Randomized Design (CRD) one, namely the ripening time. Design with 5 treatment factors: ripening stage tomatoes (redness less than 10%) without ripening (Control), 2 days ripening (P1), 4 days ripening (P2), 6 days ripening (P3), 8 days ripening (P4). Observations were made on the variables of moisture content, weight of 1000 grains, germination and seed germination spirit simultaneously. The results showed that the time of fruit ripening had a significant effect on the development of tomato quality (physical and physiological quality of seeds). The highest seed moisture content was obtained from the control treatment, which was 49,50% then along with the ripening time of the fruit and the weight of 1000 seeds was constant. The ripening stage of broken tomatoes for 6 days resulted in the highest vigor and viability, respectively 89,66% and 86,26%.

Abstract

Sandalwood (Santalum album L.) grows naturally in Indonesia, especially in Nusa Tenggara Timur area and this is one of 22 Santalum genus species in the world. Aim of the study is to determine the effect of 2-iP and the best concentration of 2-iP to stimulate callus explant shoots of Santalum album L. This studies carried out from September 2019 up to February 2020, the explants used were callus from bud culture from previous studies. The explants were planted at the Tissue Culture Laboratory, Faculty of Agriculture Udayana University Pulau Moyo street, Denpasar. This study used a completely randomized design (CRD) with 5 treatments, namely: (2-iP 0.0 ppm, 2-iP 0.5 ppm, 2-iP 1.0 ppm, 2-iP 1.5 ppm, 2-iP 2.0 ppm). The results showed that the addition of ZPT 2iP on WPM + 0.01 ppm NAA had a significant and very significant effect on the number of shoots, number of leaves and shoot length and had no significant effect on the emergence of shoots. The M1 treatment (WPM + 0.01 ppm NAA + 0.5 ppm 2-iP) showed the fastest time (1,55 MST) for the emergence of shoots on sandalwood callus explants. Treatment without the addition of zpt 2-iP (M0) could increase the number of shoots (2.87 pieces), number of leaves (5.59 strands) and shoot length (1.64 cm).

Abstract

Kelor (Moringa oleifera) is a plant that grows in tropical climates including Indonesia. All parts of this plant can be used as medicine and other natural products. The purpose of this study was to determine the bioactive compounds contained in moringa stem bark and the level of toxicity expressed by an LC50 value of less than 1.000 ppm so that it can be used as traditional medicine and other natural products. Identification of bioactive compounds in moringa stem bark using the GC-MS analysis method and toxicity test on Artemia salina Leach shrimp larvae using the Brine Shrimp Lethality Test (BSLT) method. Based on the results of the analysis using GC-MS showed that moringa bark extract contains 14 bioactive compounds. The highest bioactive compounds in the 3 peaks were secondary metabolites in the form of phenols and monoterpenoids. The toxicity test of moringa bark extract against Artemia salina Leach larvae showed that the higher the concentration, the higher the percentage of mortality of Artemia salina Leach, so that the calculated LC50 value of moringa bark extract was toxic, which was 149,689 ppm.

Abstract

This study aims to determine the status of soil quality, limiting factors, and provide direction for land management, as well as make a map of the status of soil quality on stroberi land in Pancasari Village. The methods used in this research are field survey methods, laboratory analysis, and soil quality determination. Soil samples were taken by the purposive sampling technique on each homogeneous land unit. Determination of SLH was done by overlaying soil type maps, slope maps, and stroberi land used maps in Pancasari Village. Soil quality indicators measured as minimum data set (MDS): soil texture, volume weight, porosity, C- Organic, pH, Cation Exchange Capacity (CEC), Base Saturation (BS), nutrients (N, P, and K), and C-biomass. The results showed that the soil quality at the research site was moderate in SLH 1 (Buyan Hamlet), while the good soil quality was found in SLH 2 (Dusun Peken), SLH 3 (Dasong Hamlet, Buyan Hamlet), SLH 4 (Dasong Hamlet, Buyan Hamlet), SLH 5 (Dusun Peken, Dusun Buyan) and SLH 6 (Dusun Dasong). The limiting factors for soil quality in the research site were nutrients BS. Based on the results of the study, it can be suggested that the directions for soil management at the research site, namely by adding organic matter.

Abstract

Fusarium wild or wilt disease that attacks banana plants is caused by the pathogenic fungus Fusarium oxysporum f.sp. cubense This disease is difficult to control because it lasts a long time in the soil by forming chlamydospores. Currently, the control of this disease is still using synthetic fungicides, but this method can cause damage to the ecosystem. Biopesticide is one of the environmentally friendly control of plant pathogens because biopesticides use biological agents. The purpose of this study was to export rhizoplan bacteria from banana plant roots which have antifungal activity against F. oxysporum f.sp. cubense. The results showed that rhizoplan bacteria were able to inhibit the growth of Fusarium oxysporum f.sp. cubense fungal colonies on potato dextrose agar (PDA) media with an inhibitory percentage of 90.90% when compared to the control. The results of the bacterial filtrate test of rhizoplan at a concentration of 50% were able to inhibit the growth of the fungus Fusarium oxysporum f.sp. cubense with an inhibitory percentage of 92.72%.
