Abstract

Palm oil (Elaeis guineensis Jacq.) is one of the most important plantation crops in the agricultural sector. However, during the dry season the production of palm oil is decreasing, due to the reduced availability of water especially on peatlands. One way to overcome this problem is by the use of Hydrogel Plus technology (Hydrogel based bagasse with the addition of Pseudomonas fluorescens). This study aims to determine the role of Hydrogel Plus (Hydrogel with the addition of Pseudomonas fluorescens) to the growth and production of palm oil on the peat during the dry season. The method used in this research is the experimental method using Completely Randomized Design. Treatment was done by 4 treatments and each treatment was repeated 5 times. So the experimental unit amounted to 20 units. The treatments include (P1) Control, (P2) Hydrogel application (P3) Application of Pseudomonas fluoresces suspension and (P4) Hydrogel Plus applications. Based on the result of the research, it can be concluded that Hydrogel administration with the addition of Pseudomonas fluorescens bacteria tends to have a significant effect on leaf diameter, leaf number and height of plant at each treatment and only at plant height on treatment of Pseudomonas fluorescens and only hydrogel treatment which has no effect real utilization of Hydrogel Plus can provide the effect of palm oil plant growth and production to be a specific effort as an alternative technology in sustainable palm oil management in peatlands during the dry season.

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 (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

Single-phase motors are vital components in industrial infrastructure that require continuous monitoring and control systems to ensure operational availability and prevent fatal damage due to overheating or unstable mechanical loads. This research aims to design and implement a monitoring system based on wireless communication technology using the NRF24L01 module operating at a frequency of 2.4 GHz. The system is designed to monitor motor operational parameters in real-time, which include engine temperature, vibration levels, rotational speed (RPM), as well as essential electrical parameters such as voltage, current, and electricity frequency. The system architecture utilizes an ESP32 microcontroller as the main processing unit for data acquisition from various integrated sensors, which is then transmitted wirelessly via the NRF24L01 transceiver to ensure fast data delivery in industrial environments. Data integration is carried out through an efficient digital ecosystem, including the ThingSpeak platform for graphical data visualization, Google Spreadsheets for automated data archiving for long-term analysis, and the Blynk application as a remote control interface for the Variable Frequency Drive (VFD) to regulate motor speed precisely. The testing methodology was conducted in an open area environment (line of sight) to test transmission reliability and sensor accuracy. The test results show that communication using NRF24L01 can reach an effective distance of up to 220 meters. Furthermore, the system's accuracy demonstrates a very stable performance with an average error rate below 2.1%, where this error value applies consistently across all sensor parameters integrated into the system.
