Abstract

This Crystal Guava was introduced in Indonesia in 1991 by the Taiwan Technical Mission. Various attempts have been made to achieve maximum productivity results, but these efforts have not been fully successful due to constraints such as pest attacks. Pests that attack crystal guava fruit are fruit fly pests. Fruit fly pests are pests that damage plants, especially types of horticultural crops, especially fruit and vegetable plants. Fruit fly attacks in Indonesia reach 50% and when the fruit fly population is high, the attack intensity can reach 100%. The purpose of this study was to find out the types of plant extracts that are effective and effective in attracting fruit flies in pest control, to find out the optimal concentrations to attract fruit flies in pest control in guava crystals and to find out the best time to apply extracts to attract flies. fruit in pest control on crystal guava plants. The data obtained from this study were presented in a factorial randomized block design (RBD) with 3 factors. This study consisted of 27 treatment combinations and 1 control with 3 repetitions and each treatment in one repetition there were 5 samples. Observational data were analyzed using Analysis of Variance (ANOVA) and interpretation of the data was carried out by further testing using the Honest Significant Difference (HSD) test at 5% level and orthogonal contrast test.

Abstract

Watermelon (Citrullus lanatus) is a widely consumed and cultivated fruit in Indonesia, cherished for its numerous benefits, high economic value, and short plant life. To enhance watermelon quality, plant breeding is employed, aiming to develop superior hybrid varieties. This study, conducted between September and November 2022 on PT. Aditya Sentana Agro's experimental land, evaluated candidate hybrid watermelon varieties (codes 3078, 3079, 3080, 2844, 2845) against comparison varieties (Winda, Mardi, Black Panther, Palguna). Using Randomized Complete Block Design (RCBD) with one genetic factor at 9 levels, repeated 3 times, a total of 27 experimental units were established, each consisting of 10 plants, summing up to 270 plants. Qualitative variables such as fruit skin color, pattern color, flesh color, and shape, along with quantitative variables like fruit weight, length, diameter, dissolved solids, flowering day, skin thickness, and percentage of fruit damage, were observed. The research revealed variations in fruit weight, length, diameter, dissolved solids, and flowering day among the different varieties. Promising candidates for new varieties were identified as codes 2845 and 3078 based on these quantitative traits. This study contributes valuable insights into the potential advancements in watermelon breeding, emphasizing the importance of selecting varieties with desirable characteristics for improved agricultural outcomes.

Abstract

Husk through composting techniques. However, information about the characteristics of soybean husk still needed to be studied more deeply. This caused coagulation of primary metabolites which had a very important biological functions as an energy source, fuel and intermediates for planting, the formation of RNA and DNA structural work (ribonucleic acid and deoxyribonucleic acid), this could be used to help explore the profile carried out in soybean husk degradation. Detection of carbohydrate compounds in this study used Gas Chromatography–Mass Spectroscopy (GC–MS) because it was a powerful tool in characterizing compost. The purpose of this study was to detect carbohydrate compounds in compost made from soybean husk and cow manure. Thus, further information obtained could be used as recommendations in handling soybean husk, especially as organic fertilizer through composting techniques.The study was conducted using a Randomized Complete Block Design (RCBD) with 5 composting arrangements with five replications. Related to payments were: C1: soybean husk (100 %), C2: cow manure (100 %), C3: soybean husk: cow manure (50 %: 50 %), C4: soybean husk: cow manure (75 %: 25 %) and C5: soybean husk: cow manure (25 %: 75 %). Data were analyzed using GC–MS and Least Significant Difference (LSD). Based on analysis using GC–\MS on compost, six sugar compounds were detected. While the treatment that showed the highest area of the curve was C5 (25 % soybean husk: 75 % cow manure), this result was directly proportional to the Least Significant Difference (LSD).

Abstract

Vermicast is a used soil from worm maintenance that is product composting from its maintenance in the form of organic fertilizer and it is very suitable for plants. Vermicast contains various ingredients needed by plants that is hormones such as gibberellins, cytokinins, and auxins, and contains of nutrients (N, P, K, Mg and Ca) and Azotobacter sp. which is a non-symbiotic N-fixing bacterium which can help enrich the N element for plants. In the use of vermicast can be solid or liquid. The purpose of this research is to determine the effect of dosage and vermicast with different ingredients of feed as organic fertilizer for shallot. This research was conducted at the FPP Experiment Garden UMM in Tegalgondo Village with a height of ± 560 m above sea level. The study used a Randomized Block Design with two factors. The first factor: worm feed ingredients (K) consist of (K1); Blotong waste (K2); rumen waste (K3); combination of blotong and rumen waste. The second factor: the dosage of administration (U) consists of (U1); 4 Ton / ha (U2); 5 Tons / ha (U3); 6 Tons / ha (U4); 7 tons / ha. This research included nutrient content in vermicast and on the growth of shallot including: Length of plant, number of leaves, number of tubers, weight of fresh plant, weight of dry plant. The results of this research showed that the dosage and feed ingredients given had no significant effect on plant height parameters, number of leaves, weight of fresh plant, and weight of dry plant of shallot (Alium asconolicum L.) for However it was given significant effect for the height parameters of the plant at the age of 13 HST and the number of leaves at the age of 13 HST. And the best is the combination of K3U3 (Vermicast which is given a combination of blotong and rumen waste feed ingredients) with a dosage of 54 grams / plant.
