Abstract

The ridge gourd plant (Luffa acutangula L.), native to India, thrives in Southeast Asian countries, including Indonesia, and holds significant value in traditional medicine. This study, conducted from September to December 2022 on PT Aditya Sentana Agro's experimental land, aimed to identify superior genotypes with high yield potential for ridge gourd production. Employing a Completely Randomized Group Design with one factor (genotype) and three replications, the research focused on qualitative (e.g., stem and leaf characteristics, flower and fruit attributes) and quantitative variables (e.g., leaf width, stem dimensions, flowering and harvest age, fruit dimensions, weight, yield, and storability). Notable findings include variations in fruit skin color as a qualitative trait. In terms of quantitative traits, certain variables such as leaf width, male flowering age, harvest age, fruit diameter, fruit length, and weight per fruit did not exhibit significant differences among genotypes. To enhance ridge gourd production, the study suggests the development of varieties with high yields and early maturation. This could contribute to the plant's adaptability in both highland and lowland environments. The comprehensive evaluation of qualitative and quantitative traits provides valuable insights for selecting the best candidate varieties to improve ridge gourd cultivation and productivity.

Abstract

Oyster mushroom (Pleurotus ostreatus) has a high nutritional content and is low in fat. Oyster mushrooms have the advantage that they can grow in various media naturally (on woody tree trunks) and other media such as sawdust, corn straw, bagasse, peanut shells, and other similar media. Mushrooms are foodstuffs that have a high nutritional content. One type of mushroom that is often consumed is oyster mushrooms. Oyster mushrooms are high in carbohydrates and protein but low in fat. The need for oyster mushrooms every year has an increase of 5%, so that in 2015 the need for oyster mushrooms reached 21.9 tons / year. Growing media is one of the important factors that greatly affect the growth of fungi. The substrate of the fungus must be high in organic matter. Some alternative materials that can be used as material for mushroom media come from agricultural waste or waste such as corn straw and bagasse. The purpose of this study is to obtain a combination of media compositions in the cultivation of white oyster mushrooms that are appropriate for the production and quality of white oyster mushrooms. This research was carried out at the Agrotechnology Education Park (TAMESIA), Faculty of Agriculture and Animal Husbandry, University of Muhammadiyah Malang in December 2021 – June 2022. The resource obtained were analyzed using a simple Non-Factorial Complete Randomized Design / (RAL) which was then further tested using BNJ level of 5%. The treatment response showed an influence on the growth of the mycelium, the wet weight of the harvest, harvest dry weight as well as the nutrient content of white oyster mushrooms.

Abstract

Basil is one of the indigenous plants, that has the potential to be used as a plant that is cultivated intensively in Indonesia. Basil include as one of the shrubs that can grow in almost all areas with a fairly dense canopy appearance. Each plant has different growing conditions. Basil can be grown in all regions of Indonesia. The purpose of this study was to identify the response of 2 types of basil against the use of N fertilizer dose on the early growth. In the growth process, plants require sufficient nutrients so that the physiological processes in plants’ organs can be held properly. The nutrients used by plants can be sourced from within the soil itself or in the form of fertilizers that have been put into the soil. Plants will grow properly if the elements needed by plants are fulfilled. Plants need sufficient N, P, and K nutrients for system growth. The elements of N and P are needed in the growth of proteins, carbohydrates, and nucleic acids. Basil plants are leafy vegetable plants that remarkably require Nitrogen in the optimal amounts of the growth process. The research was carried out from February to April 2022 at the Experimental Field of the Faculty of Agriculture and Animal Husbandry at the University of Muhammadiyah Malang. The design used in this study was the factorial Randomized Complete Block Design (RCBD) with a treatment dose of Urea fertilizer in basil type. The results showed that there was no interaction between the types of basil and the dose of urea at all the observation parameters. On the other side, the type of basil affects the parameters of the number of leaves, plant height, and total fresh weight where the type of tidore basil was better than other types of basil. Furthermore, the urea fertilizer dose treatment affected the number of leaves, plant height, and total fresh weight where the better urea fertilizer dose was N125.

Abstract

The research aimed to explore the impact of vermicompost fertilizer dosage and application timing on kale (Brassica oleracea var. Acephala) varieties. Conducted in Sukoharjo Village from July to September 2020, the study implemented a Randomized Complete Block Design with two factors: vermicompost dosage (D0: NPK 2 g/plant/untreated, D1: 250 g/plant, D2: 500 g/plant, D3: 750 g/plant) and application time (T1: planting, T2: 7 days after planting, T3: 14 days after planting). Analysis revealed no interaction between dosage and application time. Doses of 250 g (D1), 500 g (D2), and 750 g (D3) significantly differed in plant height, leaf number, stem diameter, leaf area, and fresh and dry weights. Notably, the application time at planting (T1), 7 days after planting (T2), and 14 days after planting (T3) significantly affected leaf number. In conclusion, the study found no interaction effect between vermicompost dosage and application time on kale. Doses of 250 g, 500 g, and 750 g exhibited significant differences, impacting plant growth and dry weight. Application times at planting, 7 days after planting, and 14 days after planting significantly influenced leaf number. These findings emphasize the importance of proper dosage and timing for optimizing kale growth with vermicompost fertilizer, contributing to sustainable agricultural practices.

Abstract

Strawberries (Fragaria sp.) are a popular fruit and have high co mmercial value worldwide. Strawberry production continues to increase, but challenges related to temperature and environment affect fruit growth and quality. Temperature is a major factor in strawberry growth. Increased temperature can also affect fruit size, weight, and color, as well as sweetness. This study used a literature search method to analyze the impact of temperature and environment on strawberry growth. To overcome these challenges, the use of greenhouses is one of the appropriate techniques for climate engineering. Greenhouses create suitable temperature conditions and protect plants from adverse climatic conditions and can maintain optimal temperatures for strawberries. Nonetheless, it is necessary to consider the use of shading techniques in greenhouses. Relative humidity also plays an important role, and dehumidification techniques, such as dehumidification ventilation, are required to maintain optimal internal conditions.

Abstract

Porang (Amorphophallus muelleri Blume.) is a type of tuber plant that is widely available in Indonesia and has tremendous potential and prospects to be developed in Indonesia. Porang is widely exported from Indonesia to several countries. The demand for porang exports continues to increase while the production of porang is still low. In vitro culture is an alternative solution in porang plant propagation to meet the needs of many porang seeds and in a relatively short period of time. Provision of growth regulators in the media can affect the growth of porang. This study aims to obtain information whether there is an interaction between IBA and TDZ in the media, to obtain information on the effect of adding IBA and TDZ with different concentrations on the growth of porang plantlets. This research was conducted using MS medium which was then added with IBA with a concentration of 0.5 ppm, 1 ppm and added ZPT TDZ with a concentration of 0.5 ppm, 1 ppm and 1.5 ppm. The results of this study showed that there was no significant difference between the emergence of shoots and the time of emergence of leaves from all treatments. The I1T3 treatment (IBA 0.5 ppm + TDZ 1.5 ppm) was the best combination treatment in this study by showing the fastest root emergence time (6 MSI), the highest average number of shoots (7.25 shoots), the average number of shoots the highest number of roots (3.67 roots), the highest average number of leaves (6 strands) and the highest average shoot height (1.33 cm).
