Pengaruh jarak tanam dan pupuk kompos pada pertumbuhan dan hasil tanaman bawang merah

The purpose of this study was to determine the effect of spacing and compost on the growth and yield of shallots and their interactions. This research is a factorial experiment with a basic design using a randomized block design (RBD) carried out in paddy fields located in Angseri Subak, Angseri Village, Baturiti District, Tabanan Regency. The results showed that the interaction between the treatment of spacing with compost had no significant effect on all observed variables. The highest fresh weight of tubers per clump was obtained at a spacing of 20 cm x 25 cm, which was 38.73 g, increasing by 30.93% compared to the lowest yield at a spacing of 20 cm x 10 cm, 26.75 g. The highest fresh weight of tuber per clump was obtained by giving 60 tons ha-1 compost which was 34.81 g, increasing by 11.50% when compared to the lowest yield in the treatment without compost ie 30.79 g

APPLICATION OF FERTILIZATION TIME AND NITROGEN DOSAGE ON PEANUT PLANT (Arachis hypogaea L.)

Abstract This study aims to determine the effect of treatment of fertilization time and dosage of nitrogen to the growth and yield of peanut plants. This experiment is a two-factor experiment with incomplete randomized block design. The first factor is the time (S) of fertilizer consisting of three levels: During planting (S0), 15 days after planting (S1), 30 days after planting (S2), The second factor is the dosage of Nitrogen (N) fertilizer consisting of three levels: 25 kg/ha (N1), 50 kg/ha (N2). The results showed that treatment of fertilization time and a dose of nitrogen showed no significant effect on plant height, maximum leaf number, leaf area index, the total pod containing, total void pod, total pod number, oven dry weight of oven plants, and harvesting index. The interaction of nitrogen dose with a time of fertilization gave a very real effect to most observed variables except for maximum plant height, maximum leaf number, leaf area, harvest index that is not significant. The high dry weight of seed oven per plant was obtained at the fertilizer interaction treatment at 15 days after planting and the dose of nitrogen 25 kg/ha was 30.33 g and or increased by 152.75% and when compared with the control of 12.00 g. From a result of regression analysis got an optimum dose of nitrogen fertilizer that is 34.15 kg/ha with the dry weight of oven seeds per plant maximum 26.73 g.

Physicochemical and antioxidant properties of Apis cerana honey from Lombok and Bali Islands

Limited honey production worldwide leads to higher market prices, thus making it prone to adulteration. Therefore, regular physicochemical analysis is imperative for ensuring authenticity and safety. This study describes the physicochemical and antioxidant properties of Apis cerana honey sourced from the islands of Lombok and Bali, showing their unique regional traits. A comparative analysis was conducted on honey samples from Lombok and Bali as well as honey variety from Malaysia. Moisture content was found slightly above 20% in raw honey samples from Lombok and Bali, adhering to the national standard (SNI 8664:2018) of not exceeding 22%. Both honey types displayed pH values within the acceptable range (3.40–6.10), ensuring favorable conditions for long-term storage. However, Lombok honey exhibited higher free acidity (78.5±2.14 meq/kg) than Bali honey (76.0±1.14 meq/kg), surpassing Codex Alimentarius recommendations (50 meq/kg). The ash content, reflective of inorganic mineral composition, was notably lower in Lombok (0.21±0.02 g/100) and Bali honey (0.14±0.01 g/100) compared to Tualang honey (1.3±0.02 g/100). Electric conductivity, indicative of mineral content, revealed Lombok and Bali honey with lower but comparable values than Tualang honey. Hydroxymethylfurfural (HMF) concentrations in Lombok (14.4±0.11 mg/kg) and Bali (17.6±0.25 mg/kg) were slightly elevated compared to Tualang honey (6.4±0.11 mg/kg), suggesting potential processing-related changes. Sugar analysis revealed Lombok honey with the highest sucrose content (2.39±0.01g/100g) and Bali honey with the highest total sugar content (75.21±0.11 g/100g). Both honeys exhibited lower glucose than fructose content, aligning with Codex Alimentarius guidelines. The phenolic content, flavonoids, and antioxidant activity were significantly higher in Lombok and Bali honey compared to Tualang honey, suggesting potential health benefits. Further analysis by LC-MS/MS-QTOF targeted analysis identified various flavonoids/flavanols and polyphenolic/phenolic acid compounds in Lombok and Bali honey. The study marks th

Pemberian Dosis Biourine Sapi dan Media Tanam Pada Beberapa Variabel Pertumbuhan dan Hasil Ekonomis Tanaman Pakcoy (Brassica chinensis L.)

The purpose of this study was to determine the effect of giving a cow's bio-urine dose and the composition of the planting medium and its interaction on several growth variables and economic yield of pakcoy plants. This research was conducted at the Experiment Station of the Faculty of Agriculture, Warmadewa University. This research activity was carried out in April to June 2018. The experiment consisted of two factors: the first factor was the dose of bio-urine of the cow consisting of 4 levels, namely 0 ml/polybag, 10 ml/polybag, 20 ml/polybag, 30 ml/polybag. The second factor, the planting medium consists of 3 levels, namely soil + cow manure, soil + husk charcoal, soil + sawdust. Experiments are designed with (RAK). Treatment of bio doses of cow urine, planting media, and interactions between bio doses of cow's urine and planting media showed very different. Interaction between 30 ml/polybag of bio urinary cow fertilizer with soil fertilizer + cow fertilizer which gave an economic oven oven dry weight of 7.93 g ± 0.38 times increased by 79.20% from the lowest 0.01 g ± 0.38 introduction of interaction when measuring cow's urine urine 0 ml, 10 ml, and 30 ml with soil planting media + sawdust. The use of 30 ml/Polybag bio-urine doses and soil + cow fertilizer can be used for the highest yield and growth of pakcoy plants

Abstract This study aims to determine the effect of biochar dose from urban waste and the concentration of eco-enzymes and their interactions on the growth and yield of shallots. The research was carried out in the greenhouse of the Faculty of Agriculture,Warmadewa University with an altitude of 25 m above sea level, and took place from April to June 2021. This study used a factorial randomized block design method consisting of two factors. The first factor is the dose of biochar with 4 levels (0; 5; 10; and 15 tons ha-1), while the second factor is the concentration of eco-enzyme which consists of 4 treatment levels (0; 7.5; 15.0; and 22.5 ml l-1). The results showed that the interaction between the dose of biochar and the concentration of eco-enzyme had a significant effect on the fresh weight of the stover per clump and had a very significant effect on the dry weight of the stover per clump, but had no significant effect on other variables. The treatment dose of biochar and eco-enzyme had a very significant effect on all observed variables. The results showed that the biochar and eco-enzyme treatments had a very significant effect on all observed variables. The application of biochar and eco-enzyme has a very significant effect on all observed variables. The provision of biochar treatment from urban waste was able to increase the fresh weight of tubers in the 15-ton ha-1 treatment, which was an increase of 39.40% compared to without biochar, while the highest fresh fruit weight was obtained in the eco-enzyme treatment of 22.5 ml l-1, which increased by 29.77% compared without eco-enzyme.
