Abstract

The Mucuna bracteata plant has various benefits in the world of oil palm plantations. Apart from being a ground cover plant, Mucuna bracteta is also a source of organic matter in oil palm plantations. The availability of less arable land makes the need to develop Mucuna bracteata cultivation as a benchmark in anticipation of the impact of the increasing availability of arable land in oil palm plantations. A study has been carried out to determine the effect of P fertilizer dose and watering frequency on the growth of Mucuna breacteata, which has been carried out in the Education and Research Garden (KP-2) Akademi Komunitas Perkebunan Yogyakarta which is located in Papringan, Depok, Sleman, Yogyakarta. This study uses a factorial design consisting of two factors arranged in a complete random design. The first factor is the application of various doses of P fertilizer consisting of 3 levels, namely a dose of 1.5 g/plant, a dose of 3.0 g/plant, and a dose of 4.5 g/plant. The second factor is the frequency of watering which consists of 2 levels, namely 1 time a day and 1 time 2 times a day. The data of the research results were analyzed with various fingerprints at the real level of 5%. If there is a real difference, it will be continued with a test Duncan Multiple Range Test (DMRT) real level 5%. The results of the study showed that the application of P fertilizer with doses of 1.5 g, 3.0 g, and 4.5 g as well as the frequency of watering 1 time a day and 1 time 2 times a day, showed that the interaction of the two treatments had a real effect on the parameters of plant height, number of leaves, fresh weight of crown, and dry weight of crown. Meanwhile, the parameters of root fresh weight, root dry weight, and total number of root nodules showed no real interaction. However, the interaction of the two treatments has an effect on each treatment alone or separately.

Abstract

Siamese orange (Citrus nobilis L.) was a type of fruit widely cultivated and produced in Bali, but its utilization was not optimal. Siamese oranges were usually used for religious ceremonies, and if excess, they would lead to waste. Siamese oranges contain vitamin C, phenols, flavonoids, and limonene as antioxidants. In addition, peel contains 30% pectin. The combination of Siamese orange fruit and peels into fruit leather with the Zero waste concept (utilizing all parts of the Siamese fruit has great potential as a functional food product). Functional food is a product that is not only filled with nutrients but also has health benefits. Fruit leather is a processed product from fruit skin that has plastic characteristics obtained from pectin content of ingredients. This study aimed to determine the right concentration of fruit peel puree addition to produce siamese fruit leather with the best characteristics and its potential as a functional food. Randomized Block Design (RGD) was used with six treatment levels in addition to siamese peel puree concentration (0%; 5%; 10%; 15%; 20%; dan 25%), repeated three times to obtain 18 experimental units. Observed variables included Vitamin C by UV-Vis spectrophotometry, antioxidant activity by DPPH, and moisture content by gravimetric and sensory characteristics on hedonic test of colour, taste, aroma, texture, and overall acceptance. Data obtained were analyzed using analysis of variance, followed by Tukey test. According to raw materials, the assumption of Siamese fruit leather with the right concentration of Siamese peel puree has potential as a functional food.

Abstract

The study was to determine the effect of the time of application from NASA liquid organic fertilizer on the generative phase of sponge plants (gambas). In cultivating plants, there are several obstacles faced such as less fertile soil and fertilization that is not on target, causing production results to be not optimal. One way that can be done to increase crop production is using NASA's POC. This research was carried out at Lahan Percobaan of the Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru. The research method used was a study using a one-factor Randomized Group Design (RGD) with 4 treatments and 5 tests so that 20 experimental units with a NASA LOF concentration of 2 ml.l-1 water were obtained. The treatment to be applied is: P0 = without giving NASA LOF, P1 = giving NASA LOF (application at 2 WAP), P2 = giving NASA LOF (application at age 2 and 4 WAP), P3 = giving NASA LOF (application at age 2, 4 and 6 WAP). The results showed that the timing of NASA's LOF It has no effect on the parameters of fruit length, fruit diameter, fruit weight and number of fruits of sponge plants, but has a noticeable effect on the parameters of the number of male flowers and the number of female flowers of sponge plants. NASA's POC application with a time interval of 3 times (P3) showed the best results in the parameters of the number of male flowers as many as (9.32) flower florets and (3.28) florets the number of female flowers.

Abstract

Nagara cowpea seeds are susceptible to deterioration during storage, thus seed viability performance must be improved with various techniques including seed invigoration. Organic priming is an invigoration technique that can be obtained from several plants that contain growth regulators. Water hyacinth is an aquatic plant in swampy areas that can be used as a raw material for organic priming. This study aims to determine the response and the best concentration of water hyacinth root extract on the growth of two cowpea varieties. This study used a completely randomized design (CRD) split plot with the main factor being cowpea varieties (G) consisting of 2 levels, G1 (Nagara cowpea) and G2 (KT9 cowpea). The subplot factor is water hyacinth root concentration (C) consisting of 4 levels C0 (without priming), C1 2.5%, C2 5.0%, C3 7.5%. The results showed that the application of water hyacinth root extract affected the growth of two cowpea varieties on plant height, number of branches and number of leaves. The highest plant height was in KT9 cowpea soaked with 5% concentration of root extract. The highest number of branches in Nagara cowpea soaked in water hyacinth root extract at concentration 2.5%. The highest number of leaves in cowpea KT9 soaked in water hyacinth root extract at concentration 7.5%.

Abstract

The application of integrated agricultural technology of duck and azolla rice can increase nutrients for plants from duck manure, loosen the soil, minimize weeding, and reduce farmers' production costs. Azolla protein content is about 23 to 30% and has a low lignin content so it is easily digested by livestock. This study aims to examine the effect of the number of ducks and azolla on the growth and yield of rice plants. The research will be conducted in Paloh Village, Samalanga District, Bireuen Regency from July to October 2024. This study used a factorial pattern Randomized Group Design (RGD) consisting of two factors. The first factor is the dose of azolla (A0: control, A1: 2 t ha-1, A2: 4 t ha-1), the second factor is the number of ducks per hectare (I0: control, I1: 800 heads ha-1, I2: 1200 heads ha-1, I3: 1600 heads ha-1). The observed variables were plant height, number of tillers, potential yield ha-1 and rice yield. The results showed that azolla treatment on rice plants had a very significant effect on plant height at 45 days after transplanting, yield potential and rice yield but no significant effect on plant height at 30 and 45 days after transplanting, number of tillers at 30, 45 and 60 days after transplanting. The treatment of ducks in rice plants had a very significant effect on plant height at 45 days after transplanting, number of tillers at 45 days after transplanting and yield potential, significantly affected plant height at 60 days after transplanting and rice yield but had no significant effect on plant height at 30 days after transplanting, number of tillers at 30 and 60 days after transplanting. The best results were found at 4 tons of azolla ha-1 and 1600 heads ha-1.

Abstract

Kelompok Tani (KT) Surya Makmur represents a growing community committed to urban agriculture and sustainable food production such as Chilli, Lettuce, and spinach in Yogyakarta. However, challenges related to manual irrigation practices, inconsistent watering schedules, and resource management have highlighted the need for more sophisticated irrigation methods. This study integrated a drip irrigation system with a smart plug-based timer, leveraging the power of automation to optimize water use, reduce manual labor, and ensure consistent plant hydration. The installation’s design was made using Canva editing software. The installation of the drip irrigation systems includes the construction of a water reservoir tank base, assembly of irrigation channels with PVC pipes and 16mm PE hoses, emitters, and dripper sticks, and then installation of mist sprayers in the greenhouse. In this study, the tests carried out were the actual emitter flow rate, evaporation rate, and performance tests, including the coefficient of variance (CV) and emission uniformity (EU). Based on the study's results, the coefficient of variation (CV) value of 0.04% indicates good performance. The emitter with a theoretical flow rate of 8L/hour has an actual flow rate of 8.33L/hour, conforming to the equipment specifications of 94.9%. The average evaporation in the test field was recorded at 8.13 mL/hour. This study concluded that implementing the drip irrigation system has helped KT Surya Makmur reduce labor for manual irrigation practices, maintain a consistent watering schedule, and increase resource utilization efficiency.

Abstract

Celery (Apium graveolens L.) originates from Southern Europe and was first described by Carolus Linnaeus in Species Plantarum (1753). In Indonesia, this plant is known as seledri. Celery is an annual herbaceous plant that grows in the form of grass or shrubs. It has an unbranched structure consisting of roots, stems, and leaf stalks. Hydroponic cultivation provides a controlled growth environment, which can optimize plant development. Liquid Organic Fertilizer (LOF) derived from tofu residue contains essential nutrients, namely N (1.2%), P (0.10%), and K (0.12%), which are crucial for plant growth. This study aimed to evaluate the effect of tofu residue-based LOF application and determine the optimum concentration for the growth and yield of celery cultivated using a wick hydroponic system. The research was conducted at BSIP (Agricultural Instrument Standardization Center), Bali. Randomized Completed Block Design (RCBD) was used with six treatment levels: (A1) 100 ml/L water, (A2) 200 ml/L water, (A3) 300 ml/L water, (A4) 400 ml/L water, (A5) 500 ml/L water, and (A6) 600 ml/L water, with four replications, resulting in a total of 24 experimental units. Statistical analysis revealed that the application of tofu residue-based LOF had a highly significant effect on all observed parameters. The results showed that the 400 ml/L water treatment produced the best outcomes, with a fresh plant weight of 14.18 g and an oven-dry weight of 1.78 g.

Abstract

The frozen beef market is experiencing significant growth, driven by urbanization, rising incomes, and increasing consumer demand for convenient, high-quality protein sources. This study investigates consumer segmentation and purchasing behavior in this market, focusing on optimizing product attributes for sustainability-oriented marketing strategies. A cross-sectional quantitative design was employed, utilizing online surveys to gather data from 385 valid respondents. K-means clustering identified three distinct consumer segments: price-oriented consumers (35%), quality-oriented consumers (45%), and sustainability-conscious consumers (20%). Price-oriented consumers, predominantly from low-income groups, prioritize affordability and product availability, showing limited concern for sustainability attributes. Quality-oriented consumers, typically middle-income, emphasize product quality, hygiene, and safety certifications in their purchasing decisions. Sustainability-conscious consumers, predominantly high-income individuals, prioritize eco-friendly packaging and certifications, demonstrating high involvement and willingness to pay a premium for sustainable products. Regression analysis revealed key factors influencing purchase behavior: price sensitivity for low-income consumers, product quality and safety certifications for middle-income consumers, and sustainability attributes for high-income consumers. Younger and more educated consumers were more responsive to sustainability, while older consumers placed more value on traditional attributes. These findings emphasize the need for targeted marketing strategies, including affordability-focused campaigns for price-sensitive consumers, quality-driven branding for mid-level buyers, and sustainability-focused messaging for eco-conscious consumers. The study also highlights the broader implications of promoting sustainable practices in meat production to align with global Sustainable Development Goals (SDGs) and the increasing consumer demand for ethical consumption
