Abstract

Vegetable crops are one of the horticultural commodities with a great opportunity to be developed, because of their relatively high nutritional contents. The production of pakcoy plants in Indonesia experienced fluctuation from 2021 as much as 727,467 tons, which increased in 2022 to 760,608 tons and decreased in 2023 to 686,876 tons. One of the efforts to optimize pakcoy production is to optimize photosynthesis product, because plants need sufficient organic matter and water. This research aimed to determine the growth and yield response of pakcoy plants to the level of goat manure fertilizer dosage and watering frequency. This research was conducted in a home garden in Pandeglang, Banten. The research used a factorial Randomized Block Design (RBD) consisting of two factors. The first factor was the level of goat manure fertilizer dosage (P) which consisted of three levels, namely 157 g/polybag (P1), 189 g/polybag (P2), 220 g/polybag (P3). The second factor was the frequency of watering (F) which consisted of four levels, namely watering once a day (F1), watering twice a day (F2), watering once every two days (F3), watering twice every two days (F4). The results showed that the dosage level of goat manure fertilizer 157 g/polybag (P1) or equivalent to 50 tons/ha gave the highest effect on the variables of plant height and leaf length. The treatment of watering frequency twice a day (F2) showed a significant effect on the variable of plant height, plant fresh weight, root fresh weight, plant marketable weight and root dry weight.

Abstract

Neem (Azadirachta indica) is a type of forest tree where almost all parts of the plant, such as the stem, leaves and seeds, contain bioactive compounds that can be used as botanical pesticides. The aim of this research was to determine the effective concentration of botanical pesticide solution from neem leaf extract against the mortality of brown planthopper (Nilaparvata lugens) on Inpari 32 rice variety. The study was conducted from February to March 2025 in Kampung Kadupinang, Mandalasari Village, Kaduhejo Subdistrict, Pandeglang Regency, and at the LPHP Laboratory Region 2 Pandeglang, Banten Province. The experiment used a Completely Randomized Design (CRD) with four replications and a single factor, which was the concentration of neem leaf extract botanical pesticide at six levels: M0- (control without treatment), M0+ (control with brown planthopper without treatment), 15%, 20%, 25%, and 30%. Observed parameters included brown planthopper mortality (%), lethal time 50% (LT50), lethal concentration 50% (LC50), fresh weight of rice plants, and dry weight of rice plants. The results showed that the 30% concentration had a highly significant effect on brown planthopper mortality. 30% concentration induced the fastest mortality (144 hours), though it failed to achieve 50% mortality. Fresh weight of rice plants was not significantly affected by the neem leaf extract treatment, with the best average value of 3.54 grams. Dry weight of rice plants was significantly influenced by the neem leaf extract treatment, with the highest average value of 1.56 grams. The fastest brown planthopper mortality occurred at the highest concentration.

Abstract

Manila Sapodilla (Manilkara zapota (L.) Van Royen). Generally known as a long-lived plant. Sapodilla plants are tropical plants which are quite widely distributed in Indonesia. All parts of the manila sapodilla plant can be used from the fruit, leaves and stems as traditional medicine and for making other preparations. However, one of the problems is that sapodilla seeds have a hard, waterproof skin layer, which causes sapodilla seeds to experience dormancy and have difficulty germinating. This research aims to determine the effect of gibberellin soaking time and H2SO4 concentration levels on the germination of manila sapodilla (Manilkara zapota (L.) Van Royen) seeds. This study used a completely randomized design with two factors, the first factor, namely the long soaking treatment for gibberellin (L), which consisted of 3 levels, namely soaking for 6 hours (L0), soaking for 12 hours (L1), and soaking for 18 hours (L0). L2). the second factor, namely the H2SO4 concentration (K), which consists of 4 levels, namely without H2SO4 (K0), 40% H2SO4 concentration (K1), 60% H2SO4 concentration (K2), 80% H2SO4 concentration (K3). Gibberellin soaking treatment with a soaking time of 6 hours gave the best effect on growth speed parameters (2.44%/day). Treatment with a H2SO4 concentration level of 80% gave the best effect, namely on the parameters of maximum growth potential (88.89%), germination power (86.67%), growth speed (2.88%/day), as well as on the parameters of seeds not growing as much as (13.33%). There was no interaction between the length of gibberellin soaking treatment and the level of H2SO4 concentration on all parameters observed.
