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%).

Abstract

Growth of Plantlets of Vanda tricolor Orchid In-Vitro on the Cassava Pulp-Enriched MS Medium.Addition of organic matter into the culture medium is commonly used for increasing the source of sugar, vitamins and amino acids. The aim of this study was to determine the effect of the cassava pulp on the growth of Vanda tricolor plantlet, and to investigate appropriate dose for the optimal growth of plantlets. The experiment utilised a Randomized Completely Design with six treatments i.e. UO (MS medium without any organic matter), U1 (MS medium + 35 g/L cassava pulp), U2 (MS medium + 40 g/L cassava pulp), U3 (MS medium + 45 g/L cassava pulp), U4 (MS medium + 50 g/L cassava pulp), and U5 (MS medium + 45 g/L cassava pulp) with five replicates. The result showed that addition of cassava pulp significantly increased number of leaf, number of root and dry weight of plantlets. The highest number of root (i.e. 5.8) was obtained with addition of 50 g/L cassava pulp, while the highest dry weight of plantlet (i.e. 0.28 g) was on addition of 55 g/L cassava pulp.

Abstract

Asymbiotic Germination of Dendrobium bicaudatum Orchid Seeds on Media with In Vitro Addition of Tomato Extract. Dendrobium bicaudatum is a natural orchid that needs to be preserved. Orchid seeds propagation naturally (symbiotic) has a low success rate. Orchid seeds do not have an endosperm. Asymbiotic germination with in vitro culture techniques can be an alternative solution for the propagation of orchid seeds. This study aimed to determine the effect of giving tomato extract on modified media on the asymbiotic germination of Dendrobium bicaudatum orchid seeds. This research used the Completely Randomized Design with five treatments of tomato extract concentration, namely 0%, 5%, 10%, 15%, 20%, with 4 replications. The variables observed in this study were the time and percentage of phase 1; time and percentage of phase 2; time and percentage of phase 3; time and percentage of phase 4; time and percentage of phase 5; and time and percentage of phase 6. The results showed that the tomato extract treatment had a significant or very significant effect on the germination of Dendrobium bicaudatum orchid seeds and the best treatment for the fastest and the highest percentage of germination from protocorm to First Leaf Primodium was the addition of tomato extract with a concentration of 15% or 20%, and a concentration of 0% tomato extract for the early stages of swelling of the embryo.

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

The difficulty in obtaining seeds and the high price of seedlings prompted the implementation of the Campus Intellectual Product Business Development Program (PPUPIK) for superior local fruit seedlings of seedless BalineseWani at the Faculty of Agriculture, Udayana University. In order to support the successful development of the Seedless Wani Seed Business Unit, it is necessary to have a more in-depth study using a SWOT analysis. The research was conducted in Banjar Duren Taluh, Belimbing Village, Pupuan District, Tabanan Regency in April - August 2020. The study was conducted with a SWOT analysis to see the performance of business units by determining a combination of internal factors (strength and weakness) with external factors (opportunity and threats). Furthermore, the EFI and EFE matrices are made. The results of the two matrices are then entered into a qualitative model, namely the SWOT matrix to formulate the company's competitive strategy. Based on the results of the EFE and EFE value analysis, the Seedless Wani Seed Business Unit is in cell one where in this position the business unit can implement a growth strategy with vertical integration by taking over the supplier function or by taking over the function of the distributor. This is the main strategy for companies that have a strong and highly competitive market position. Keywords: Bali local fruit, Seedless wani seedling, SWOT analysis
