The application of biochar and water table at one month after planting on growth and yield of shallot.Â Jurnal Lahan Suboptimal: Journal of Suboptimal Lands. 8(2):202-212.Â The success of onion self-sufficiency is the arrangement and growth of production centers that are not only concentrated in Java. The research aimed to evaluate the effect of biochar application and water table treatment on growth and yield of shallot plant. The research was conducted in Experimental Farm of Agriculture Faculty, Sriwijaya University at 2019. Materials used consisted of shallot bulb of Bima Brebes variety, oil palm shells biochar, paper bag, and plastic bag. While the tools used were hoe, gauge, pH meter, basin, scale, and oven. Factorial Randomized Block Design was used with two factors and three replicates. The first factor was biochar dosages consisting of P1 (51 g/plant) and P2 (102 g/plant) and the second factor was soil water table consisting of T0 (no water table treatment), T1 (10 cm of water table below soil surface), T2 (15 cm of water table below soil surface) and T3 (30 cm of water table below soil surface). The observed parameters included plant height, leaf number, tiller number, total bulb fresh weight, bulb fresh weight, bulb dry weight and root length. Results showed that the application of biochar and water table treatment statistically affected the growth and yield of shallot plant. The effect on both growth and yield parameters were obtained from the combination of P2T3. Correlation was found between plant height and leaf number, total bulb fresh weight and bulb fresh weight.

Wheat seeds, one of the orthodox seed types, naturally experience a decline in quality during long-term storage. This deterioration is a complex process that involves various factors throughout the seed's lifecycle. However, seed deterioration studies are based on static approaches. Therefore, moving from static to dynamic indicators, which describe changes in the state of seed biological systems over time, would be exciting. The study aimed to estimate the vigor and storability of wheat seeds based on a systems approach. The research was carried out using a systems approach, while the stages of the research were as follows: literature study and data collection from several scientific journals, preparation of flowcharts, models, simulations, and validation. The results showed that the estimation of wheat seed deterioration could be predicted through a systems approach. The estimation of wheat seed deterioration is a system that involves many variables that are interrelated and occur simultaneously. The following equations can estimate the wheat seed deterioration model: ROS(t) = ROS(t - dt) + (-H2O2) x dt; H2O2 = ROS x Changes index of H2O2; MDA = 4.62271 + (18.4012 - 4.62271) x exp (-22.2767 x H2O2 1.70613); FFA = 123.336 x exp (-10.1865 x H2O2); germination = 2.30234 + (109.524 - 2.30234) / (1 + exp (11.4657 x ln ('MDA' / 9.39342))). During storage, antioxidant enzymes that degrade reactive oxygen species (ROS) become inactive. The accumulation of ROS leads to membrane damage, resulting in decreased vigor, which is characterized by reduced germination rates.

Response of Durian Leaf Explants to Naphthalene Acetic Acid Application on Woody Plant Medium. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, Palembang 20 Oktober 2025. (pp. xâ€“y).Â Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Â Â Durian is one of the leading commodities in South Sumatra, boasting high economic potential; however, its propagation is still constrained due to the difficulty in propagating it generatively. This research aimed to determine the growth response of durian leaf explants to the application of the auxin NAA (Naphthalene Acetic Acid) in WPM (Woody Plant Medium). Research was conducted using a completely randomized design (CRD) with five levels of NAA concentration: N0 = 0 ppm, N1 = 1 ppm, N2 = 2 ppm, N3 = 3 ppm, and N4 = 4 ppm. Each treatment unit consisted of 10 culture bottles, repeated three times. The results of this research showed that the N0 treatment produced a 33% callus growth rate with a 13% contamination rate, while the N1 treatment showed a 6.7% callus growth rate with a 36.7% contamination rate. N2 produced a 60% explant survival rate, a 36.7% callus growth rate, and a 43% contamination rate. In contrast, treatment N3 showed the highest contamination rate of 76.7% and a live explant percentage of 23%. Treatment N4 showed a live explant percentage of 100% and a callus growth percentage of 6.7%. During the 8-week observation period, the highest callus formation occurred at a concentration of 2 ppm. This research concluded that NAA concentrations in the range of 0â€“2 ppm were more optimal for inducing callus growth, while higher NAA concentrations tended to increase the contamination rate and inhibit callus formation.

Padang, T. V., Irmawati, I., Susilawati, S., Kurnianingsih, A., Halimi, E.S., Andini, W., & Amiros, N. (2025). The Effect of Naphthalene Acetic Acid in Murashige and Skoog Medium on Durian Leaf Callus Induction. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, PalembangÂ 20 Oktober 2025. (pp. xâ€“y).Â Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Durian is a key commodity with high economic value in South Sumatra, but the generative propagation of this plant still faces obstacles. This research aimed to determine the effect of NAA (Naphthalene Acetic Acid) application in MS (Murashige and Skoog) medium on callus induction in durian leaf explants (Durio zibethinus Murr.). The research used a completely randomized design (CRD) with five levels of NAA concentration, namely N0 = 0 ppm, N1 = 1 ppm, N2 = 2 ppm, N3 = 3 ppm, and N4 = 4 ppm, each repeated three times with each unit consisting of 10 culture bottles. The research results showed that the N0 treatment produced 83% live explants with 16.7% contamination, N1 produced 13% callus growth with 36.7% contamination, while N2 produced 80% live explants, 20% callus growth, and 20% contamination. Treatment N3 had the highest contamination at 73% with 26.7% live explants, while N4 produced 100% live explants but only 6.7% callus growth. During the 8-week observation period, the highest callus formation occurred in treatment N2. This research concluded that low NAA concentrations in the range of 1â€“2 ppm are more optimal for inducing callus in durian leaf explants, while excessively high NAA concentrations inhibit callus formation and increase the risk of contamination. These results can be used as a reference in optimizing durian tissue culture media to accelerate vegetative propagation and support the development of tissue culture techniques in woody plants.
