Abstract

Avocado production in Banten Province fluctuates due to suboptimal nutrient provision. This study used local variety YM avocado seedlings from Lebak Banten which were propagated by grafting. This study aims to determine the effect of liquid organic fertilizer (LOF) concentration from several types of banana stems on the growth of grafted avocado seedlings (Persea americana Mill.). This study used a factorial Randomized Block Design (RBD) consisting of 4 concentration levels: 0, 150, 300, and 450 ml/l and 3 types of banana stems: nangka banana stems, kepok banana stems, muli banana stems. Based on the results of the study, the administration of LOF with a concentration of 300 ml/l gave the best effect on the parameters of seedling height increase, leaf number increase and leaf greenness index. A concentration of 450 ml/l gave the best effect on the parameters of seedling height increase, stem diameter increase, leaf length increase and leaf width increase. While the type of LOF from nangka banana stems gave the best effect on seedling height increase. There is an interaction between the concentration and type of banana stem on the parameters of the comparison of the length and width of avocado plant leaves.

Abstract

This study aims to determine the effect of various concentrations of leaf fertilizer on red chili (Capsicum annum L.) of the Laju F1 variety cultivation. This research was conducted at the experimental garden Instalasi Penelitian dan Pengkajian Teknologi Pertanian Balai Penelitian Tanaman Sayuran Serpong (IP2TP Balitsa Serpong). The method used in this research was the experimental method of Randomized Block Design with one factor, namely giving various levels of concentration leaf fertilizer consisting of six treatment levels namely 0; 1; 2; 3; 4; and 5 g/l with a total of 5 replication to obtain 30 experimental units. The results showed that leaf fertilizer has a significant effect on the average plant height parameter at 5 weeks after planting (WAP) (53.12 cm); stem diameter 3 WAP (3,99 mm), 4 WAP (6.85 mm), and 5 WAP (8.87 mm); fruit length per plant at 2nd harvest (15.55 cm); and fruit diameter per plant at 1st harvest (9.26 mm) and at 2nd harvest (9.77 mm); fruit weight per plant (1157,54 g); and fruit weight per plot (2673,34 g). The treatment of various concentrations of leaf fertilizers showed no significant differences in the parameters of the amount of fruit per plant.

Abstract

Pollution (Hg) of the soil due to gold mining activities reduces soil fertility and endangers the environment. The purpose of this study was to analyze effectiveness of biochar from palm empty bunches (PEB) and compost from rubber leaf litter as remedial materials to improve the soil chemical properties of Hg-contaminated tailings. An experimental method using a factorial Randomized Group Design was applied with varying doses of biochar and compost. Parameters observed included Hg concentration, pH, Organic C, Total N, and P and K availability. The results showed that the gold mine tailings have chemical properties that are not ideal for supporting plant growth, including a slightly alkaline pH, very low Organic C and total nitrogen contents, and mercury levels that exceed safe limits (The critical concentration of mercury (Hg) in soil is 0.3-0.5 ppm). The use of biochar from oil palm empty fruit bunches and rubber leaf litter compost proved to be able to increase pH, Organic C, total nitrogen, phosphorus, and available potassium. The treatment with the highest dose combination (30 tons PEB biochar and 20 tons rubber litter compost per ha) succeeded in increasing total N to 5.40%, available P by 175.67 mg/1kg, available K by 7.39 mg/100g, and Organic C by 0.98%. However, the amount of mercury remained high, so further remediation using larger doses of ameliorants and stricter tailings management is needed to sustainably reduce heavy metal pollution.

Abstract

Tomato (Solanum lycopersicum L.) production in Banten has significantly declined due to land constraints and suboptimal cultivation practices, necessitating sustainable alternatives like fermented rice wash water (RWW) and optimal planting media. This study aimed to determine the most effective combination of RWW concentration and growing media composition to enhance tomato growth and yield in polybag cultivation. The research was conducted from November 2025 to March 2026 at Universitas Sultan Ageng Tirtayasa, Banten, using a factorial Randomized Complete Block Design. Factors included RWW concentrations (0, 50, 100, and 150 mL/L) and four media compositions (soil; soil+manure; soil+husk charcoal; and soil+manure+husk charcoal).The results showed that the soil-only medium (B0) produced the best vegetative performance, particularly for plant height and stem diameter. Specifically, the interaction of 100 mL/L RWW and soil (S2B0) yielded the highest plant height of 35.60 cm at 4 weeks after transplanting. Furthermore, a significant interaction was observed in the generative phase, where 50 mL/L RWW combined with soil and rice husk charcoal (S1B2) achieved the highest productivity, reaching a fruit weight of 158.00 g and 11.33 fruits per plant. These findings suggest that integrating 50 mL/L RWW with porous media is the most effective strategy for optimizing tomato yield

Abstract

Superior seed quality is one of the keys to success in growing shallots. The purpose of this research was to analyze the effect of the concentration of biofertilizers and types of planting media on the growth of shallot seed origin of True Shallot Seeds (TSS) in the nursery. This research used a split-plot design consisting of two factors. The first factor is the concentration of biofertilizers, and the second factor is the type of planting medium. The results showed that the application of biofertilizers increased the growth of the shallot seed origin of TSS than without the application of biofertilizers. The application of biofertilizer at 1.5 mL.L-1 water gave the best results regarding the number of leaves per seedling and fresh weight. However, treatment with different concentrations of biofertilizers made no significant difference; treatment with concentrations of 1 mL.L-1 water was more efficient for the growth of shallot seeds. The type of planting media treatment did not significantly affect all parameters observed for the growth of shallot seed origin of TSS. There is an interaction between the concentration of biofertilizers and the type of planting media on the growth of shallot seed origin of TSS, namely the number of leaves aged 5 weeks after seedling, while for other parameters, there is no interaction between the concentration of biofertilizers and the type of planting medium on the growth of shallot seed origin of TSS.

Abstract

The research aimed to examine the quality of coffee waste in solid and liquid material in promoting the growth and yield of caisim plants (Brassica chinensis var. parachinensis). This research was conducted from November until December 2023 in Sukabumi Roadway, RT. 002 RW. 001 Ciwedus Village, Cilegon District, Cilegon city, Banten. The experimental design used in this study was a Randomized Block Design (RBD) consisting of one factor, which is with eight treatment levels: without fertilizer application (control) (P0), 10 g of solid coffee processing waste compost (P1), 20 g of solid coffee processing waste compost (P2), 30 g of solid coffee processing waste compost (P3),  100 ml liquid coffee processing waste compost (P4), 150 ml liquid coffee processing waste compost (P5), 200 ml liquid coffee processing waste compost (P6), and 250 ml liquid coffee processing waste compost (P7). The results showed that treatment P5, gave the best results in terms of growth in plant height (26.30 cm), number of leaves (9.00 leaves), plant fresh weight (43.23 g), root wet weight (4.03 g), and root length (17.80 cm). For solid coffee ground treatment, the P3 treatment has a significant effect on plant height (25.30 cm), number of leaves (7.00 leaves), plant wet weight (22.60 g), and root length (17.03 cm). The findings of this research theoretically support the theory proposed by Putri et al. in 2017, indicating that the application of 30g/150 ml had the most favorable impact on the growth of lettuce plants (Lactuca sativa L.).
