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

Selada (Lactuca sativa) merupakan tanaman hortikultura yang dikonsumsi secara global, baik di iklim sub-tropis maupun tropis dan menjadi salah satu jenis tanaman sayuran yang bernilai ekonomi tinggi. Idealnya semua benih harus memiliki kekuatan tumbuh yang tinggi, sehingga bila ditanam pada kondisi lapangan yang beraneka ragam akan tetap tumbuh sehat dan kuat serta berproduksi tinggi dengan kualitas baik. Kemunduran suatu benih dapat diterangkan sebagai turunnya kualitas atau viabilitas benih yang mengakibatkan rendahnya vigor dan jeleknya pertumbuhan tanaman serta produksi. Salah satu cara untuk mempercepat perkecambahan benih adalah pemberian zat pengatur tumbuh (ZPT). Bahan alami yang dapat digunakan sebagai substitusi ZPT diantaranya adalah air kelapa. Penelitian ini telah dilaksanakan di Laboratorium Pertanian Presisi, Politeknik Manufaktur Negeri Bangka Belitung pada bulan Februari sampai dengan bulan Maret 2025, menggunakan Rancangan Acak Lengkap (RAL) satu faktor dengan 4 perlakuan yaitu : Akuades, Air kelapa 50%, Air kelapa 75% dan Air kelapa 100%. Variabel pengamatan yang dilakukan adalah sebagai berikut : persentase perkecambahan, indeks kecepatan perkecambahan, waktu rata-rata perkecambahan, panjang plumula, panjang radikula, berat basah dan berat kering. Berdasarkan hasil penelitian dapat disimpulkan bahwa perendaman air kelapa berpengaruh terhadap perkecambahan benih selada. Pengaplikasian terbaik diperoleh pada konsentrasi 50%.

Abstract

Fruit sorting based on ripeness and weight is still largely done manually, which poses a risk of inaccuracies, delays, and labor inefficiencies. This research aims to design and implement an automatic mango sorting system that can detect ripeness levels (raw, ripe, rotten) and measure the weight of the fruit. This system uses TCS3200 color sensors, a 20 kg Load Cell weight sensor, and is controlled by an ATMega328P microcontroller. A 20x4 LCD module is used as a user interface. The methods used include acquiring RGB value and weight data, classifying ripeness levels based on predetermined color thresholds, and real-time weight data processing. Testing results show that the system can accurately identify the skin color of mangos and display the weight with an average deviation of ±0.05 kg. This prototype has been proven to improve the accuracy, speed, and efficiency of the sorting process compared to manual methods. The developed tool is a tangible step towards the implementation of smart agriculture, particularly in the post- harvest process, and has the potential for further development in other fruit types.

Abstract

Rice (Oryza sativa L.) is a staple food crop that serves as the primary source of carbohydrates for the majority of the Indonesian population. Swamp lands have distinctive characteristics due to prolonged water saturation, often leading to nitrogen losses through denitrification, volatilization, and leaching processes. This study aims to determine the extent to which variations in the dosage and intensity of foliar urea fertilizer application can affect nitrogen distribution in plant tissues (roots, stems, and leaves) and how it influences the grain weight per plot. The study used a completely randomized block design (CRBD) with 3 replications. The first factor was the concentration of urea solution, consisting of 4 levels: 3% (D1), 6% (D2), 9% (D3), and 12% (D4). The second factor was the intensity of urea fertilizer application, consisting of 3 levels: once (I1) (2 weeks after planting), twice (I2) (2 and 4 weeks after planting), and three times (I3) (2, 4, and 6 weeks after planting). The application of urea fertilizer on leaves with variations in dose and intensity significantly affects nitrogen uptake and rice grain yield. Increasing the dose up to 12% and applying it up to three times enhances nitrogen uptake and grain yield. A dose of 9% with three applications produces the highest nitrogen uptake, while a 12% dose results in the highest grain weight without a significant difference between one and three applications

Abstract

The use of local ameliorants has the potential to be an effective solution in improving the quality of post-tin mining soil that is poor in nutrients and has a coarse texture. This study aims to analyze the effect of oil palm bunch ash, coconut shell ash, and chicken manure on the germination of two kale varieties (Nemo and Nita) in degraded media. The study used a two-factor Completely Randomized Design (CRD) at the Precision Agriculture Laboratory of the Bangka Belitung State Manufacturing Polytechnic. The parameters observed included plumule length, radicle, fresh weight of seedlings, fresh weight of roots, and dry weight of roots. The results showed that the percentage and germination capacity did not differ significantly between treatments. However, radicle length, fresh weight, and dry weight of seedlings showed a significant effect, with the best response achieved by the coconut shell ash and oil palm bunch ash treatments. Local ameliorants also caused positive changes in soil physical properties, especially in the color and texture of the media. In conclusion, local ameliorants proved effective in improving the initial conditions of post-mining soil and successfully supported kale germination.
