Abstract
The cultivation of aquatic species faces a significant challenge due to water quality degradation, which impacts farming operations and poses a threat to livelihoods. To contribute to advancing aquaculture informatics and enabling more precise and convenient monitoring of aquaculture ponds, this study introduces an IoT-based Water Quality Monitoring System for Fishponds. This system is designed to measure pH and salinity values in real-time, aiming to address the pressing need for continuous monitoring and management of water quality parameters for cultivating milkfish (Chanos chanos). Users can remotely access and control measurements by integrating the prototype with the Blynk IoT system, ensuring that water quality remains within optimal thresholds or 6.5 to 8.5 pH for acidity and 18 to 29 ppt for salinity. In addition, the system is equipped with an alert system to notify end-users when the parameters exceed predetermined limits promptly. The prototype received an average functionality score of 4.325 and an efficiency score of 4.13. The error percentages recorded were 0.027% for acidity, 0.187% for salinity, and 4.36% for overall effectiveness. This system enhances cultivation security, enabling farmers to make informed decisions and take timely actions to maintain optimal water quality conditions in fishponds.

Abstract
Golden Apple Snail (GAS) (Pomacea canaliculate L.) is a source of macro nutrient which have the potential to be the main raw material for biostimulants for plant growth. Biostimulants are made through a fermentation process and produce an unpleasant aroma. The addition of organic ingredients which have strong aromatic compounds such as Kaffir Lime peel leaves is expected to cover up the unpleasant aroma of the GAS extract produced. Apart from that, users of this biostimulant will not be disturbed by the aroma of GAS extract when applied in the field. Therefore, the purpose of this research is to determine the characteristics of the fermentation results of GAS extract with the addition of Kaffir Lime leaves in four GAS extract formulations: lime leaves, including a ratio (ml:gr) of 100:0 (GAS extract without lime leaves); ratio 100:1; 100:5; 100:10. Kaffir Lime leaf slices measuring 1-2 cm2 are mixed in the fermentation process which is carried out for 21 days. Anova analysis and Duncan’s advanced test showed that there were significant differences in aroma parameters, but there were no differences in C-Organic, N-Total, P2O5, K2O, and C/N Ratio, color and consistency. The aroma produced from fermentation in the 100:10 ratio formulation is the aroma of Kaffir Lime leaves with a strong quality and can cover the fishy aroma of GAS. Therefore, the addition of Kaffir Lime leaves can have the potential to improve the aroma quality of the GAS Biostimulant product, but does not reduce the nutrient content in it.

Published: January 2025

Abstract

Protium javanicum is an indigenous Indonesian plant belonging to the Burceraceae family, utilized in traditional medicine. The leaves possess bioactive constituents including phenolics, flavonoids, steroids, tannins, and terpenoids, which have possible antioxidant properties. The isolation of these phenolic compounds can be achieved through extraction using ethanol as a solvent. Phenolic compounds exhibit varying chemical characteristics and polarity. The polarity of the ethanol solvent significantly enhances the solubility of phenolic compounds. This study aimed to determine the ethanol concentration that produces Protium javanicum leaf extract with optimal antioxidant activity. This study utilized five distinct levels of solvent concentration: 90%, 80%, 70%, 60%, and 50%. The findings suggested that a 90% ethanol solvent yielded extracts exhibiting the maximum antioxidant activity (IC50 = 20.60 ppm), total phenolic concentration of 243.81 mg GAE/g, a yield of 21.90%, and total flavonoids of 33.02 mg QE/100g. The extract contains substances classified as flavonoids, terpenoids, and amino acids. This group of flavonoids exhibits potential as an antioxidant.

Abstract
Improving the quality of coffee plant growth is one of the keys to a coffee plantation’s success in Indonesia, as it strives to produce high-quality coffee. Good nutrient uptake in plants is a determining factor in producing plants that have good growth. The research was carried out with the aim of increasing nutrient uptake in coffee seedlings through the application of Plant Growth Promoting Rhizobacteria (PGPR) and Vesicular Arbuscular Mycorrhiza (VAM). The research was carried out from April to September 2024 at the Wire House and Bioscience Laboratory, Politeknik Negeri Jember. The study employed a Randomized Complete Block Design (RCBD) using a combination of Plant Growth Promoting Rhizobacteria and Vesicular Arbuscular Mycorrhiza at several doses as a treatment. The results showed that both PGPR and VAM enhanced nutrient absorption efficiency. The combination of PGPR (Plant Growth-Promoting Rhizobacteria) and Vesicular Arbuscular Mycorrhiza (VAM) significantly increases the wet and dry weight of plants, the effectiveness of nutrient assimilation, encompassing vital components such as nitrogen, phosphorus, and potassium, represents a significant aspect of consideration. Combinations of PGPR 10 g.plant−1 with mycorrhiza 10 g.plant−1 (P4) and PGPR 15 g.plant−1 with mycorrhize 10 g.plant−1 (P5), showed optimal synergy that supported the growth of coffee plants and their resistance to environmental stress.

Abstract
Indonesia’s efforts to increase rice production are driven by the goal of becoming the world’s food granary by 2045. Rainfed lowlands currently occupy 46% of all rice cultivation and hold the potential for expanding national rice production but encounter biophysical constraints and low rice productivity. Land management neglecting environmental sustainability threatens sustainable rice production. This study examines alternative technologies that can be applied to lowland rainfed paddy fields to increase productivity and environmental sustainability. This systematic literature review uses 40 references, 81% of which are primary journals related to rainfed agroecosystems, rice cultivation, and environmentally friendly systems. Research showed that efforts to advance rice productivity in rainfed fields were pursued through environmentally friendly technologies and optimization of land management, including using superior varieties, planting technology, timing of planting, water resource management, balanced fertilization, pest/disease control, and appropriate harvesting practices. Drought-adaptive varieties were the solution to increasing plant populations and shortening harvest time. Balanced organic and inorganic fertilization was also essential in managing rainfed lowland rice fields. Furthermore, the farmers’ active role, infrastructure, social, economic, and environmental support have encouraged environmentally friendly technological innovations to attain food self-sufficiency.

Abstract
The research was conducted to evaluate the haematological profiles of laying quails before and after receiving a Newcastle disease (ND) vaccine. The varying doses of Nano Se-yeast (Selenium-yeast) probiotics were tested for their effects on hematological profile such us, hemoglobin (Hb), erythrocytes, hematocrits, MCV, MCH, MCHC, leucocyte (WBC), neutrophile, lymphocytes, monocytes, and trombosit of laying quails. Two hundred laying quails were randomly allocated into four treatments and each treatment consisted of five replicates, with ten birds in each replicate. The first treatment was a control (T0), basal diet without supplementation Nano Se-Yeast, while the second (T2), third (T3), and fourth (T4) treatments were administered basal feed supplemented with Se-yeast containing 1x 108 CFU/g at levels of 0.5, 1.0, and 1.5 g/per kg of feed. The quails received vaccinations with ND vaccine strain La Sota seven days following treatment with yeast supplementation. Blood samples were taken forty-eight hours before vaccine and three days after the vaccine. The results show MCV and MCHC profiles were found to be significantly affected by yeast treatment, but hemoglobine, erythrocytes, hematocrites, MCH, RDW-CV, leucocytes, eosinophils, basophils, neutrophils, lymphocytes, and thrombosit were not significantly affected, particularly before vaccine treatment. This finding suggests that Se-yeast supplementation is beneficial under little-stress conditions.

Abstract
Green synthesis can produce broiler bone nanocalcium citrate, which could serve as a novel food supplement for Indonesian traditional meatballs known as ‘bakso’. The purpose of this investigation was to ascertain the impact of broiler bone nanocalcium citrate fortification on the sensory properties and color of beef meatballs. Ingredients such as beef, tapioca flour, egg whites, salt, shallots, garlic, monosodium glutamate, pepper, soy protein isolate, sodium tripolyphosphate, carrageenan, ice, lime juice, and aquadest were included in the research materials. As part of the treatments, broiler bone nanocalcium citrate was added to the total meatball dough at the following percentages: P0 (0%), P1 (0.15%), P3 (0.3%), P4 (0.45%), and P5 (0.6%). The color parameters measured included lightness (L*), redness (a*), and yellowness (b*), with each treatment replicated four times. For the evaluation of sensory properties, 40 untrained panelists implemented a hedonic test. The hedonic parameters that were evaluated included color, flavor, taste, texture, chewiness, and overall acceptability. The hedonic test results were analyzed using non-parametric analysis through the Kruskal-Wallis hedonic test, while the data from the color measurements were analyzed using a one-way analysis of variance. Duncan’s New Multiple Range Test was used for further analysis if significant differences were found (P<0.05). The results showed that different levels of broiler bone nanocalcium citrate fortification affected color measurements (lightness and yellowness) as well as sensory properties (texture, chewiness, and overall acceptability). This study concludes that fortifying beef meatballs with 0.3% broiler bone nanocalcium citrate is the best treatment, resulting in a lighter color, a more preferred texture, and chewiness.

Published: January 2025

Abstract
This research aims to study the effect of steaming time and imbibition water percentage on oil extraction from palm fruit. The independent variables used in this research were steaming time of 60, 90, and 120 minutes and imbibition water percentage of 15%, 20%, and 25%. The steaming process before extraction is carried out to facilitate the decomposition of the fruit flesh and speed up the release of oil from the palm fruit flesh. Research parameters include oil yield and quality of the oil produced, such as water content, free fatty acid (FFA) content, and impurity content. The data obtained were analyzed using the Taguchi method. Research has found that variations in steaming time and percent imbibition water had a significant effect on the yield and quality of the palm oil produced. Steaming for 120 minutes with an imbibition water percentage of 25% provides optimal yield and oil quality results. Steaming Time (A) has the most significant effect on CPO yield, as indicated by both the SNR and Mean values. These findings are expected to increase the efficiency and effectiveness of the palm oil extraction process.

. Borophene fills a crucial gap in the 2D material repertoire thanks to its intrinsic metallicity and relative stability in air. However, in view of practical applications including borophene, it is crucial to master its synthesis to enable controlling its structure and thus tuning its properties. This review focuses on its current bottom-up syntheses, i.e. physical vapor deposition and chemical vapor deposition. Indeed, borophene’s structure is different from the bulk boron one, which excludes its top–down synthesis. The impact of substrate characteristics, temperature, pressure conditions, and precursor molecules on borophene’s phase and domain size is analyzed, along with key characterization techniques. The review extends to hydrogenated borophene and bilayer borophene for a comprehensive understanding of boron bonding and substrate interactions. Given the importance of ambient stability and transferability of 2D boron layers for device applications, a thorough comprehension of borophene oxidation is imperative. The review thus also discusses potential solutions to mitigate oxidation-related challenges.

Published: January 2025

Abstract
The reduced switch multilevel inverters are used in many applications specially in renewable energy system. They have a smaller number of semiconductor devices, complexity and thus lower cost and power losses. A reduced-switch multilevel inverters (MLIs) with quadruple boosting capability have been investigated in this study by implementing an optimized harmonic pulse width modulation (OPWM) technique. As an example, a nine-level quadruple boosting inverter, operating at fundamental frequency, is analysed to reduce the dominant lower order harmonics such as third, fifth, and seventh-order harmonics in the output voltage along with control on fundamental component. The particle swarm optimization (PSO) algorithm is employed to obtain the optimize the switching angles using a constrained nonlinear objective function. The computational results have been used to simulate the nine-level quadruple boost inverter and results shows a significant reduction in lower order harmonics. The simulation results have been verified on a prototype of nine-level quadruple boost inverter.
Adaptive Kalman filter-based time synchronization algorithm for civil aviation communication
Authors: Guo Jihong , Li Zuyan 
Published: January 2025

Abstract
The traditional synchronization algorithms often struggle to meet the stringent requirements of civil aviation communication. This paper proposes an adaptive time synchronization algorithm based on Kalman filtering (KF) to enhance the synchronization performance of civil aviation communication systems. Firstly, a dynamic clock model is established considering the characteristics of civil aviation communication, with clock offset and drift as state variables. Moreover, a step-by-step detection strategy is employed to adaptively adjust the detection range based on the statistical characteristics of synchronization errors, thereby improving the algorithm’s robustness and convergence speed. To evaluate the algorithm’s performance, a civil aviation communication system-level simulation platform is built based on ICAO standards, and various typical scenarios, such as take-off, landing, and cruising, are designed. Simulation results demonstrate that the proposed algorithm achieves significant improvements in synchronization accuracy, convergence speed, and robustness compared to classical synchronization algorithms based on phase-locked loops (PLL) and early late gates (ELD).
