Abstract

The domestic agricultural sector contributes 18% to the national greenhouse gas emissions (GHG); which is higher compared to its global counterpart. Biochar incorporation into the soils shows the potential to reduce soil GHG emissions. The objective of this study was to ascertain how biochar addition affects CO2, N2O and CH4 emissions from the soils of stallholder palm oil plants. Coffee hash was pyrolyzed at 5000C to prepare biochar, which was then ground to pass a 100-mesh sieve. Three plots (50m x 50 m) consisting of 27 subplots (1 m x 1 m) were used as the experimental design in the field. Biochar was incorporated into the soil subplots of 0, 10, and 20-ton biochar/ha. A static chamber was installed on the soil surface to collect gas generated from the soil on days 0, 5, 10, 20, 40, and 60. All gas collection was conducted at 30 min after the chamber lid installation. The soil CO2, N2O, and CH4 emissions of control soils ranged from 712 to 862, 7.28 to 9.46, and -0.0036 to 0.0014 kg/d/ha, respectively. The incorporation of 10 and 20-ton biochar per hectare decreased the emissions of CO2 and N2O up to 16.8% and 33.8%, respectively; whereas an uptake was observed for the CH4 gas. The CO2 and N2O emissions from the 10-ton/ha and 20-ton/ha biochar-incorporated soils differ significantly compared to the control soils, but the CH4 emissions do not. This result shows that biochar incorporation to the oil palm soils reduces the CO2 and N2O emissions, but not CH4 emissions.

Abstract

Gandaria fruit wine, however, is still made using a straightforward fermentation procedure, hence the final product is murky. The correct variables for judging fruit wine quality still require a number of optimization procedures to be carried out. The purpose of this research was, therefore, to compare the primary fermentation and aging effects of different commercial yeast types on the physicochemical properties of gandaria fruit wine. Aging for 14 days caused a significant decrease in the characteristics of gandaria wine produced with different commercial yeast types and concentrations compared to the freshly fermented wine. Total sugar, total acidity, vitamin C, total soluble solids, and turbidity were among the characteristics that decreased. Whereas with aging, the alcohol content and pH values increased. The gandaria wine produced with commercial yeast Pakmaya at a 2.5% concentration was found to be the best due to the alcohol content that complied with the standard for fruit wine and had the clearest resulting wine both for the primary fermentation and the 14-day aging.

Abstract

Pineapple is a fruit that is widely produced in Indonesia. Pineapple can be processed into jam or fruit spread to extend its shelf life. However, jam contains high amount of sugar. High consumption of sugar in the diet can contribute to a high kilojoules diet or known as 'energy dense' and thus contribute to the development of health problems like obesity or diabetes. Sugar has important role in the jam. It binds water molecules to build spreadable product. Pectin can also bind water molecules and cannot be digested by human body but addition of pectin as sugar replacement cannot build spreadable product because pectin molecules is much longer than sucrose. Thus, depolymerization through hydrolysis is needed on pectin molecule. Therefore, the purpose of this research was to determine the effect of different hydrolyzed pectins as substitute for sucrose in a pineapple spread. The physicochemical properties of hydrolyzed pectin (viscosity and color value) and pineapple spreads made from the hydrolyzed pectin (color value, degree of brix, water activity, syneresis and spreadability) were investigated. The results showed that pectin treated with 0.05 M of HCl for 96 h produced the best pineapple spreads based on water activity and percentage of syneresis results. Moreover, pineapple spreads made from pectin treated with 0.05 M of HCl for 96 h has the most similar color and spreadability to the one with sucrose.

Abstract

Lignin reduced the adhesion between the polymeric matrix and natural reinforcement in composite materials by its hydrophobic characteristic. Removal of lignin can be a solution to improve fiber function in composite use. This study aimed to determine the degradation of lignin at different times of pulping. The soda process was conducted at 60, 70, 80, 90, and 100 minutes of pulping using heat in a room atmosphere. Yields, lignin content, and lignin spectrum (FT-IR analysis) were measured.  The result showed the highest degradation of lignin was in 100 minutes of pulping with 80.34% lignin degradation and 3.57% lignin left in fibers. However, the yield of fibers decreased with increasing pulping time due to lignin removal. 100 minutes of pulping time showed the highest loss of fiber yield. This study showed the best pulping time for kapok fiber is 100 minutes with 3.57 % lignin remaining in the pulp.

Abstract

The use of synthetic herbicides causes many problems, including pollution, a decrease in soil organic content, and weed resistance to specific herbicides. Plants provide a source of novel phytotoxic compounds that can be evaluated in the search for efficient and ecologically safe herbicides. This research aimed to examine the allelochemical bioherbicidal activity of sambiloto (Andrographis paniculate Ness) leaf extract (SLE) to suppress weed seed germination and growth. The experiment was designed to investigate the effect of the SLE as a potent weed seed germination inhibitor and retard weed growth. In this experiment, a non-factorial randomized block design was used, with treatments SLE0 (0% Extract), SLE1 (Extract 0.1%), SLE2 (Extract 0.5%), SLE3 (Extract 1.0%), and SLE4 (Extract 1.5%). The result showed that weed height and biomass were significantly reduced after the extract was applied. The plant-based extracts contained 0.1114% flavonoids and 0.1628% tannins. The findings suggest that this sambiloto herbaceous extract has a promising future in modern plant protection as bioherbicide to suppress germination and weed growth. Therefore, the application of these bio-products could be beneficial for sustainable agricultural practices.

Abstract

The breeding of new high-yielding varieties is one of the solutions to the low productivity of soybeans in Indonesia. Superior genotypes of ‘GHJ-4 (A)’ and ‘GHJ-5 ’ were obtained in the previous study with an average weight of 13 g/100 seeds and a potential yield of 3 tons/ha. The attempt to increase the weight and size of the seeds of ‘GHJ-4’ and ‘GHJ-5’ was continued using the backcrossing method with ‘Ryoko  (>35 g/100 seeds) as a parent donor. F1 plants were obtained with an average weight of 15 g/100 seeds. This study aimed to determine the performance of the F2 generation of backcross in terms of the number of filled pods, the weight of 100 seeds, yield per plant (g), yield per plot (kg), and potential yield per hectare (tons/ha), as well as the heritability value of the genotypes. In this particular study, the F2 seeds from F1 plants were then planted and observed. This study used a non-factorial randomized block design (RBD) with 11 soybean genotypes, each consisting of 3 replications. The results showed that the F2 generations (GHJ-4XRyoko, RyokoXGHJ -5, and GHJ-4XGHJ-5) are considered as prospective new high-yielding varieties with a potential yield of ≥ 3.5 tons/ha, which have successfully restored the trait of ‘Ryoko’ and surpassed the performance of ‘GHJ-4’ and ‘GHJ-5’ as their parents in all parameters. The heritability value of the genotypes tested belongs to the high category, on the parameters of the number of filled pods (96.937 %), yield per plant (98.102 %), the weight of 100 seeds (99.132%), yield per plot (92.605 %) and potential yield per hectare (92.257 %).  For the parameters observed, the back cross yields of harvest age were 72-74 HST, the weight of 100 grains was 17-18 grams and the yield per hectare was around 4 tons/ha. The heritability value shows that the observed traits are inherited from parents on average more than 90% and the selection that will be used is pedigree selection.

Abstract

The use of artificial chemicals as fertilizers and pesticides can endanger the health of the environment and consumers, so the potential utilization of natural materials as fertilizers and pesticides needs to be increased from local sources such as golden snails and citronella. The experiment aims to get the best interaction between golden snail Liquid Organic Fertilizer (LOF) and citronella oil for rice growth and production. The experiment was carried out in the paddy fields of Jorong Paraman Ampalu, Gunung Tuleh District, West Pasaman Regency from September 2020 to January 2021 using an RBD of 2 factors with 3 replications. The first factor was the golden snail LOF concentration, namely: 0, 100, 200, and 300 ml/L. The second factor was the citronella oil concentration, namely: 0, 10, 20, and 30 ml/L. Data were analyzed with ANOVA and DNMRT at 5% and 1%. The experimental results showed that the interaction between golden snail LOF and citronella oil concentration accelerated flowering, increased panicle length, grain weight, and dry grain production per hectare, while the golden snail LOF concentration factor increased plant height, maximum number of tillers and productive tillers, panicle length, number of grains per panicle, and 1000 grain weight. The highest grain production was obtained at concentrations of golden snails LOF of 200 ml/L and citronella oils 20 ml/L, namely 9.18 t/ha. The frequency of attacks by ground beetles and golden snails decreased at a concentration of 30 ml/L citronella oil, while stink bug infestation frequency was reduced at a concentration of 10 ml/L.

Abstract

Nuggets are a product that should be stored frozen, but nuggets are often sold at inappropriate temperatures, causing physical changes such as pale color. Dayak onion extract can improve color appearance and provide added antioxidant value to tilapia nuggets. Quality testing of tilapia nuggets with Eleutherine palmifolia (Dayak onion) extract coatings has been investigated. The objectives of this research are to apply Dayak onion extract to improve the appearance of tilapia nuggets and to obtain tilapia nuggets with Dayak onion extract that meets SNI requirements. The results of organoleptic tests showed that panelists preferred tilapia nuggets with Dayak onion extract over commercial controls and nuggets. The panelists preferred tilapia nuggets with 100 ppm ethanol extract and 10000 ppm aqueous extract, both continued to the SNI conformity test. The sensory evaluation results based on SNI showed that the appearance of the tilapia nuggets with 100 ppm ethanol extract was significantly different. Adding Dayak onion extract to tilapia nuggets affected the lightness and yellowness of tilapia nuggets and gave a 'moderate orange' color to the tilapia nuggets with ethanol and aqueous extract. The selected tilapia nugget with 100 ppm aqueous Dayak onion extract meets all chemical, microbiological, and sensory requirements as SNI 7758:2013 concerning fish nuggets. Tilapia nuggets with Dayak onion extract had a brighter Moderate orange color and were preferred by panelists compared to controls and commercial fish nuggets that were moderate dark orange. Applying Dayak onion extract on tilapia nuggets can improve the appearance and it potentially contains natural antioxidants.

Abstract

In Indonesia, the production of baby corn is generally derived from composite varieties because not many varieties have been exclusively bred for baby corn purposes. This study aimed to determine the quantitative and qualitative traits of five local maize varieties to obtain potential parent materials for baby-corn-purposed lines. The research was conducted at the Experimental Field of State Polytechnic Jember using a non-factorial randomized block design with five local maize varieties (‘Kretek Madura’, ‘Bisma’, ‘Provit A1’, ‘Srikandi Kuning’, and ‘Sukmaraga’). The data obtained were analyzed with ANOVA and followed by the Fisher’s Least Significant Difference Test at a 5% error level. The results indicated that all five varieties tested met the standards of Codex for baby corn in terms of diameter, length, and qualitative traits.  In terms of plant height, female flowering, and number of ears, V1 ‘Madura Kretek’ was observed to have the most potential as it had the shortest plant height (173.60 cm), the fastest female flowering (43.64 days), and harvest age (47.67 days), as well as the highest number of ears (2.55). However, this variety showed a lower baby corn weight, which might affect the total yield. It is suggested that the next quest of parent material for the baby-corn-purposed line can be also focused on the weight of the baby corn.

Abstract

The AquaCrop model is widely used under various agro-ecological conditions to reduce farm water consumption. The study aimed to simulate, validate, and measure the performance of AquaCrop models for canopy cover, biomass and soybean crop yields cultivated within a lysimeter. This research was conducted in the experimental field of the Faculty of Agriculture, the University of Jember, Indonesia (8°09'45.1" S, 113°42'58.2" E, 101 m a.s.l). There are four treatments in 4 lysimeters, namely P1 (irrigation based on recommendation), P2 (irrigation 95-105% FC), P3 (irrigation 75-85% FC) and P4 (irrigation 55-65% FC). The AquaCrop model is calibrated using canopy cover (CC) and then validated to predict the biomass and soybean yield. The experiment revealed that the model simulates better CC, biomass, and soybean yields with full irrigation than deficit irrigation. The performance of the AquaCrop model for soybeans of the Deja 2 variety in predicting CC, biomass, and soybean yield is impressive and reasonable. For the CC we found R2 ranges from 0.956 to 0.995, RMSE 10.389% to 3,293%, NRMSE 0.154% to 0.051%, NSE 0.918 to 0.992, and d 0.980 to 0.998. For biomass the R2 is 0.842, RMSE 0.111 t ha-1, NRMSE 0.017%, NSE 0.712, and d 0.937. For soybeans production the R2 is 0.999, RMSE 0.045  t.ha-1, NRMSE 0.018%,, NSE 0.908 and d 0.970. This study demonstrated that based on WUE, 55-65% FC irrigation is the most efficient application.
