Abstract

Rice is an agricultural commodity that plays an important role in meeting the basic needs of people in Indonesia. Along with population growth, rice consumption in Indonesia continues to increase. However, the availability of agricultural land is not commensurate with the increase in population, on the contrary, its availability is decreasing. One way to increase rice productivity is land intensification through improvements in the management of production factors by using them efficiently. This research aims to determine: 1) the determining factors for rice farming production, 2) the determining factors for technical efficiency and technical inefficiency of rice farming in the Special Region of Yogyakarta (DIY). The data used is secondary data sourced from the results of the 2013 agricultural census with a sample of 3,751 farmers. Data analysis uses the multiple linear regression method estimated using Ordinary Least Square (OLS) to determine the determining factors of rice farming production. Technical efficiency is analyzed using a stochastic frontier model estimated with Maximum Likelihood Estimation (MLE). Based on the results of the analysis, it is known that rice farming production in DIY is influenced by harvest area, NPK fertilizer, organic fertilizer, pesticides, labor, irrigation systems, superior varieties, seasons and climate change. Factors that have a significant influence on the technical efficiency of rice farming are harvest area, NPK fertilizer, organic fertilizer, labor, irrigation systems, superior seeds and pesticides. The determining factors for technical inefficiency are age, education, government assistance, counseling, and field schools.

Abstract

Cut chrysanthemum flowers (Chrysanthemum indicum L.) were reported to have high economic value but faced a major constraint in the form of a short shelf life (vase life) of only 2-3 days postharvest due to high respiration and transpiration rates. This study aimed to examine the effect of sucrose solution and shallot extract concentrations and their interaction on the shelf life of cut chrysanthemum flowers, as well as to determine the best concentration. The study employed a completely randomized design (CRD) with a 4x4 factorial arrangement and three replications. The first factor was sucrose concentration (0%, 2%, 4%, 6%) and the second factor was shallot extract concentration (0%, 10%, 20%, 30%). The main observed variables included flower freshness, and color changes in flowers, leaves, and stems. The results showed that sucrose application had a highly significant effect (P

Abstract

The availability of quality spinach (Amaranthus sp.) seeds is often hampered by expiration issues that drastically reduce germination. This study aims to analyze the effectiveness of osmopriming treatment in restoring the physiological quality of expired spinach seeds and determine the most optimal time for observing radicle emergence (ER). The experiment was conducted in April–May 2025 at the Seed Science Laboratory of Lampung State Polytechnic using a one-factor Completely Randomized Design (CRD). Spinach seeds that had expired for six years were given four invigoration treatments, namely Control, 5% KNO₃, 5% PEG 6000, and 150 ppm GA₃ with four replications. The results showed that osmopriming using 5% PEG 6000 and 150 ppm GA₃ was the best treatment in significantly increasing seed viability and vigor. The 5% PEG 6000 treatment produced the highest germination rate (98.66%) and the best vigor index (82.66%), followed by GA3150 ppm which produced the fastest growth rate of 96.02% KN/etmal. In contrast, the control treatment gave the lowest results with the percentage of abnormal shoots reaching 16.00%. Through the rapid test method, the 5% PEG 6000 and 150 ppm GA3 treatments were able to trigger the fastest radicle emergence with an extreme exponential curve spike since the 16th hour after imbibition. The most optimal RE observation time was achieved at the 30th hour by the 5% PEG 6000 treatment (97.33%) and reached a perfect accumulation of 100.00% at the 42nd hour by the 150 ppm GA3 treatment. This study proves that the RE test is effective as a rapid indicator to evaluate the recovery of vigor of small spinach seedlings.

Abstract

Urban farming by cultivating microgreens is an alternative for fulfilling food security. Microgreen is a technique for cultivating vegetables in urban areas, with a harvest time of 7-14 days after sowing. Increased cowpea microgreen production is influenced by growing light and natural phytohormones. This research aimed to determine the role of grow light distance and natural phytohormones in increasing production and chlorophyll content in cowpea microgreens. This research used a Randomized Block Design (split-plot) consisting of 2 factors. The 1st factor, A1= 20 cm, A2= 40 cm and A3= 60 while the 2nd factor, B0 = Aquades, B1 = 50% Aquades + 50% Coconut Water, B2= 50% Aquades + 50% Onion Extract , B3 = Aquades 50% + Coconut Water 25% + Onion Extract 25%. The research results showed that the treatment of 50% distilled water + 25% coconut water + 25% shallot extract at a grow light distance of 60 cm produced the highest value for the plant height parameter, namely 16.70 cm. The highest chlorophyll content was in the combination of 50% distilled water + 50% coconut water at a distance of 20 cm, namely 52.97 mg/g. The 60 cm grow light distance treatment produced the highest plant height, namely 18.88 cm, the heaviest wet weight parameter using a 40 cm grow light distance, namely 1.43 grams and a 20 cm grow light distance produced a high chlorophyll content, namely 38.40 mg/g. The aquadest treatment produced the highest plant height, namely 14.33 cm, while the optimal number of leaves and fresh weight used the 50% aquades + 25% coconut water + 25% shallot extract treatment, namely 5 pieces and 1.38 g and the 50% aquades + coconut water treatment. 50% produces a high chlorophyll content of 24.87 mg/g.
