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

Abstract

The Effect of Additioning Tea Waste LOF on Growth and Products of Pakcoy (Brassica rapa L.) Plants by Wick System Hydroponic. Pakcoy (Brassica rapa L.) is one of the vegetables that can be cultivated using a hydroponic system. The wick hydroponic system is one of the hydroponic techniques used in vegetable cultivation, involving the use of standing water in the installation and passive flow circulation. The nutrients commonly used in hydroponic cultivation are the AB Mix nutrient solution. However, the use of liquid organic fertilizer (LOF) in hydroponic vegetable cultivation is an important consideration to reduce the use of inorganic fertilizers. The research objective is to determine the growth response of pakcoy cultivation with the addition of tea waste LOF, which contributes to the growth and yield of pakcoy plants. This study utilized a Completely Randomized Design (CRD) with six levels, namely 0 ml/L, 2 ml/L, 4 ml/L, 6 ml/L, 8 ml/L, and 10 ml/L, each with four replications. The research was conducted in the Experimental Greenhouse and Agronomy and Horticulture Laboratory, Faculty of Agriculture Udayana University from February to May 2023. The treatment of 10 ml/L was found to be the best concentration for the addition of tea waste LOF in promoting the growth and yield of pakcoy plants in the wick hydroponic system. The results of the regression analysis for fresh canopy weight and oven dry canopy weight have not revealed an optimal concentration. This is due to the presence of a positive linear relationship with the concentration of tea waste LOF, indicating that both weights will increase with an increase in concentration.

Abstract

The Effect of Biochar Types and Compost on Soil Microorganism Activities. This research was carried out at the plastic house of Pasraman Unud Jimbaran from January to June 2021. The type of biochar used come from waste materials such as bamboo, rice husks, coconut shells, and corn cobs, while the compost was selected according to Indonesian National Standards. The purpose of this study was to determine the biochar material from several wastes combined with compost in supporting the activity of soil microorganisms as well as the N, P, K, pH and C-organic soil. The experimental design used in this study was a Simple Completely Randomized Design with 9 treatments and 3 replications so that it became 27 experimental units. The experimental treatments consisted of: B0 (control); B1 (1.5% rice husk biochar/ha); B2(1,5% biochar bamboo/ha); B3 (1.5% corncob biochar/ha); B4 (1.5% coconut shell biochar/ha); B5 (0.75% rice husk biochar + 0.75% compost)/ha; B6 (0.75% bamboo biochar + 0.75% compost)/ha; B7 (0.75% corncob biochar + 0.75% compost)/ha; B8 (0.75% coconut shell biochar + 0.75% compost/ha). Monitoring of media humidity is carried every 2 days and stirring once a week. Observations were made at the end of the incubation period (35 days) on soil respiration, C-organic, N-total and pH. The results showed that the highest activity of microorganisms occurred in the B6 treatment (0.75% bamboo biochar + 0.75% compost)/ha. The addition of (biochar + compost) to the soil gave a significantly different effect on organic C and total soil N.

Abstract

Market demand for baby romaine lettuce (Lactuca sativa L. var. longifolia) continues to rise alongside the public’s growing preference for healthy lifestyles, yet its productivity still needs improvement. This study aims to evaluate the effect of seedling density per planting hole on the growth and yield of baby romaine lettuce using the Deep Flow Technique (DFT) hydroponic system and to determine the optimal number of seedlings. The experiment was conducted in a greenhouse in Pelaga Village, Bali, using a completely randomized design (CRD) with a single factor comprising five seedling densities (1, 2, 3, 4, and 5 seedlings per hole) and six replications, totaling 120 plants.  Growth and yield parameters were analyzed using ANOVA and LSD at a 5% significance level, with regression applied to fresh shoot and crop weight. Results showed that increasing the number of seedlings significantly affected plant height, stem diameter, chlorophyll content, fresh and dry shoot weight, and total fresh biomass. Shoot fresh weight increased linearly (Y = 97.86 + 11.71X; R² = 0.975), while crop fresh weight followed a quadratic trend (Y = 70.64 + 8.10X – 1.00X²; R² = 0.863), with the optimal yield obtained at three seedlings per hole. It is concluded that planting three seedlings per hole offers the best outcome in terms of both quality and quantity in a DFT hydroponic system.
