Abstract

Background: Celery (Apium graveolens) is a horticultural crop with significant economic and culinary value, particularly in Indonesia, where leaf celery is more commonly cultivated. Despite growing interest in hydroponic farming in regions such as Bangka Belitung, celery cultivation remains limited due to challenges in seed germination, especially under lowland and hot climate conditions. Celery seeds are known for slow and inconsistent germination due to hard seed coats and naturally occurring germination inhibitors like coumarin. Seed soaking in plant growth regulators (PGRs), including natural alternatives such as red onion (Allium cepa L) extract—rich in gibberellins and auxins—has been proposed to enhance germination and seedling vigor.Aims & Methods: This study aimed to investigate the effects of different soaking durations (24 and 48 hours) and concentrations (0%, 10%, 20%, and 30%) of red onion extract on the germination performance of celery seeds.Result: The results of this study indicate that a 24-hour soaking duration is the most effective in enhancing celery seed germination as under these conditions, the seeds experience only brief exposure to low oxygen levels. However, soaking seeds in red onion extract at concentrations of 10% to 30% resulted in lower germination parameters compared to the 0% because the concentration is suspected to be too high for celery seeds. Analysis of the interaction between soaking duration and extract concentration revealed that control seeds (without soaking or directly sowing) achieved germination performance comparable to the best treatment combination in terms of germination power, germination speed index, and mean germination time. At the same time, the highest vigor index and seedling length were observed in seeds treated with 10% red onion extract for 24 hours, which also showed similar performance to the control treatment.

Abstract

Background: Soybean is one of the most popular agricultural commodities in Indonesia, but its production is still low. Thus, it is necessary to make efforts to expand its agriculture in the form of marginal land development.Aims: This study aims to examine the effect and obtain the best treatment dose of arbuscular mycorrhizal fungi (AMF) in ultisol soil to increase the growth of soybean plants (Glycine max (L.) Merill).Methods: This experimental study employed a complete randomized design (CRD) with the treatment of arbuscular mycorrhizal fungi (AMF). The AMF treatment comprised five levels: no AMF, 4 g/polibag, 8 g/polibag, 12 g/polibag and 16 g/polibag. Each treatment was repeated four times, resulting in 20 experimental units and each experimental unit comprised three polybags so that this study used 60 polybags. The data were analyzed using Analysis of Variance (ANOVA) and continued with Duncan's New Multiple Range Test (DNMRT) at the 5% level.Result: AMF treatment is able to increase the growth of soybean plants in the parameters of plant height, number of productive branches, flowering age, number of flowers, and harvest age. The AMF treatment dose of 12 g/polybag is proven to give the best results in increasing the growth of soybean plants. The use of AMF can be an effective strategy in optimizing soybean production, especially on marginal lands.

Abstract

Celedry (Apium graveolens L.) is one type of vegetable that has many benefits, both used for daily needs and used as medicine or vitamins to determine the optimal concentration of red onion extract and soaking duration for the germination of celery plants. This study was conducted at the Agricultural Laboratory of the State Manufacturing Polytechnic of Bangka Belitung from January to February 2025. The experimental design used was a Completely Randomized Design (RAL) with 2 factors. The first factor is concentration, with four levels namely the concentration of red onion extract 0%, 10% (K2), 20% (K3), 30% (K4). The second factor is the duration of soaking for 24 hours (W1) and 48 hours (W2). The observed variables are total wet weight of sprouts (g), total dry weight of sprouts (g), length of sprout shoot (cm), and length of sprout root (cm). The data from the research were analyzed using ANOVA variance and further tested using the DMRT test at a 5%. The research results indicate that the treatment with different concentrations of red onion extract and the duration of soaking significantly affects the total wet weight of the sprouts, the total dry weight of the sprouts, and the length of the sprout apex, but does not significantly affect the length of the root apex of celery plants. The interaction between 10% onion extract concentration and 24 hour soaking effectively increases total root weight, dry weight, and seedling shoot length of celery.

Abstract

Rice is a very important and strategic commodity because it is the main source of carbohydrates for the community. Therefore, an increase in rice production is urgently needed. Swampland is considered a potential option to support food self-sufficiency, given the various advantages it has. One of the main advantages is the availability of abundant water, which is crucial in supporting plant growth, especially in uncertain climatic conditions. Fertilizer is one of the key factors in rice farming. Nitrogen (N) is one of the most important nutrients and should be available to plants. Foliar nutrition can generally increase grain yield while reducing the amount of fertilizer administered through soil application. The purpose of this study is to obtain the concentration and intensity of foliar urea application that is most effective in supporting the growth and yield of rice cultivated in swampland. The experiment was carried out using a complete group random design (RAKL) with a factorial design involving 2 factors and 3 replicates. The first factor is the concentration of urea solution, which consists of 4 levels, namely 3%, 6%, 9%, and 12%. The second factor is the intensity of the application which consists of 3 levels, namely 2 mst, 2 mst, and 4 mst, as well as 2 mst, 4 mst, and 6 mst.

Abstract

Lahan kering umumnya memiliki pH masam, kandungan bahan organik rendah, serta ketersediaan unsur hara yang terbatas, sehingga produktivitasnya belum optimal. Penelitian ini bertujuan menganalisis pengaruh pemberian hidrogel berbahan limbah daun nanas yang diperkaya Pseudomonas fluorescens terhadap perubahan sifat kimia tanah di lahan kering. Penelitian dilakukan menggunakan rancangan acak lengkap dengan tiga perlakuan, yaitu tanpa hidrogel (kontrol), hidrogel + P. fluorescens, dan hidrogel tanpa bakteri, masing-masing diulang empat kali. Parameter yang diamati meliputi pH tanah, C-organik, N-total, P₂O₅ tersedia, kation basa (K, Ca, Mg, Na), kapasitas tukar kation (KTK), kejenuhan basa, serta Al³⁺ dan H⁺ yang dapat ditukar. Hasil penelitian menunjukkan bahwa perlakuan hidrogel + P. fluorescens memberikan perbaikan paling signifikan dibandingkan perlakuan lainnya, ditandai dengan peningkatan pH dari 5,85 menjadi 6,15, C-organik dari 2,45% menjadi 4,06%, N-total dari 0,13% menjadi 0,33%, dan P₂O₅ dari 10,86 ppm menjadi 17,60 ppm. Selain itu, terjadi peningkatan KTK dan kejenuhan basa serta penurunan Al³⁺ dan H⁺ yang dapat ditukar. Temuan ini menunjukkan adanya sinergi antara fungsi hidrogel sebagai sumber bahan organik dan peran bakteri dalam meningkatkan ketersediaan hara serta menekan kemasaman tanah. Dengan demikian, kombinasi hidrogel limbah daun nanas dan P. fluorescens berpotensi menjadi strategi bioameliorasi yang ramah lingkungan untuk rehabilitasi lahan kering.

Abstract

Kiambang is an aquatic weed commonly found in Indonesian waters. Kiambang extract contains secondary metabolite compounds that have the potential to inhibit the growth of billygoat weed (Ageratum conyzoides), which is commonly found in agricultural and plantation areas. This study was conducted to determine the potential of kiambang extract as a bioherbicide against billygoat weed. The study employed a Completely Randomized Design (CRD) consisting of five concentrations of kiambang extract, namely 0%, 20%, 40%, 60%, and 80%, with four replications. The observed parameters included weed mortality percentage, weed height, and bioherbicide efficacy. A significant effect on bioherbicide efficacy was first observed at a concentration of 40%, resulting in an efficacy value of 7.18%, while the highest efficacy was achieved at 60% concentration (42.46%). Meanwhile, significant effects on weed mortality percentage and weed height were observed starting at a concentration of 60%. Kiambang extract can be utilized as a contact bioherbicide for controlling billygoat weed, commonly found in agricultural and plantation areas.
