Abstract

Tanaman padi yang menghasilkan beras merupakan komoditas utama di Kecamatan Ledokombo. Kendala yang dihadapi petani dalam budidaya termasuk cekaman abiotik berupa angin kencang pada musim penghujan. Hal ini mengakibatkan tanaman padi lokal dengan postur tinggi rentan mengalami rebah. Untuk mengatasi masalah ini, diperlukan pelatihan terkait penggunaan zat pengatur tumbuh guna mengendalikan pertumbuhan tanaman yang tinggi. Paclobutrazol (PBZ), sebagai salah satu jenis zat pengatur tumbuh, berperan penting dalam mengurangi tinggi tanaman. Pelatihan dilakukan langsung di lahan petani dengan menggunakan lima varietas padi yang berbeda. Hasil aplikasi menunjukkan bahwa padi yang ditanam oleh petani menjadi lebih pendek dibandingkan yang tidak diberi perlakuan serupa.

Abstract

In everyday life, queues often occur. Waiting at the counter to get train or movie tickets, at the toll gate, at the bank, at the supermarket, and in other situations that we often encounter Queues occur when the need for services exceeds the capacity or capacity of the service facility. As a result, users of the facility cannot get immediate service due to the busyness of the service. The Amplas Toll Gate queue is the object of this research. The Amplas Toll Gate is one of the densest toll gates that is heavily traveled by vehicles both entering and exiting. This makes it often seen a fairly long queue, especially during peak hours in the late afternoon to evening. The Medan City Government built an off ramp at the Amplas flyover in 2016. This off ramp leads directly to the Amplas toll gate. The vehicle arrival rate increases along with the queue length because vehicles can arrive faster to the toll gate. This study aims to calculate the queue length at the Amplas toll gate before and after the construction of the ramp off. Data is obtained by recording the volume of vehicles at the research location. With an average service time of 7 seconds, the queuing method produces a queue length of 11.98 meters, while the results using Pro Model software are 11.98 meters. In addition, the queue length after the construction of the ramp off decreased to 6.67 meters from before the construction of the ramp off. Promodel is a windows-based simulation software used to simulate and analyze a system.

Abstract

Identifying pathogenic fungi at the species level based on morphology, especially for leaf rust, is quite difficult. Further investigation, such as molecular techniques, is required to identify leaf rust fungi precisely. One way that can be employed is DNA barcoding. This study seeks to detect leaf rust fungi (Puccinia spp.) on sugarcane. Accurate species identification allows early detection of Puccinia kuehnii, helping farmers and extension agencies to apply targeted control strategies. A fungal sample was collected from sugarcane fields in Bondowoso, East Java, Indonesia. Morphological identification was done with an SEM, whereas molecular identification was done through DNA extraction, amplification, visualization, sequencing, and phylogenetic tree creation. The primers employed are obtained from the ITS region of ribosomal DNA, which contains enough diversity to differentiate fungi at the species level. The amplification findings revealed a DNA band of 500 bp at both loci. Sequencing results indicate that samples The sequencing results indicatethat the samples from Bondowoso are closely related to the Puccinia kuehnii sequence from NCBI. The findings of the phylogenetic tree construction revealed that samples from both locations are still associated with P. kuehnii sequences from other nations. This is the first study documenting P. kuehnii in Indonesia, especially East Java, that integrates morphological and molecular characterization.

Abstract

Genetic transformation in plants involves the insertion of isolated foreign genes into the plant genome. Sucrose Phosphate Synthase (SPS) is a key enzyme in sucrose biosynthesis, the primary sugar serving as an energy source and carbon transport molecule in most plants. Dendrobium orchids, which utilize Crassulacean Acid Metabolism (CAM), often exhibit a slow growth rate, thereby limiting their commercial potential. The insertion of the SPS gene into the orchid genome is expected to optimize the sucrose metabolic pathway, potentially influencing the rate of photosynthesis, carbon allocation, and growth characteristics of the orchid. Optimizing the optical density (OD) of the Agrobacterium suspension and the dosage of kanamycin is crucial for enhancing the success rate of the gene transformation process. This study aimed to determine the optimal concentrations of OD and kanamycin to achieve efficient SoSPS1 gene transformation in orchids. Three-month-old Protocorm-Like Bodies (PLBs) of Dendrobium Glory White were used as the explant source. The transformed explants were subsequently evaluated for the effectiveness of the kanamycin dosage, the percentage of explant shoots, the number of shoots per explant, the transformation efficiency, and phenotypic changes in the transformed plants. The results showed that a transformation efficiency of up to 40% was achieved using an Agrobacterium suspension at an OD600nm of 0.4. A lethal dose (LD50) of 100 mgL-1 kanamycin resulted in 34% of plantlets surviving post-selection. Transformation with the SoSPS1 gene in Dendrobium sp. induced distinct phenotypic plants including split leaves, swollen stems (pseudobulb), and increased shoot multiplication.

Abstract

Climate change in Indonesia has led to an increase in abiotic stress, particularly drought, which significantly affects sugarcane productivity. This research was conducted from 2024 to 2025 at the Laboratory of Molecular Biology and Biotechnology, Waste Management Unit, and Integrated Laboratory, University of Jember. The aim of this study was to evaluate the agronomic, physiological, and biochemical responses of five sugarcane varieties under drought stress conditions. The results showed that drought stress had varying impacts depending on the tolerance of each variety. The drought-tolerant transgenic variety (NXI4T) exhibited more stable responses, as indicated by lower drought and leaf rolling scores, higher soil water content (SWC) and relative water content (RWC), and relatively stable levels of chlorophyll, phenolics, and flavonoids. In addition, lower H₂O₂ accumulation and a stronger root system supported better adaptation to drought conditions.

Abstract

Sucrose Phosphate Synthase (SPS) is a key enzyme in the sucrose biosynthesis pathway and plays an essential role in regulating sucrose accumulation in plants. Overexpression of the SPS gene has been reported to enhance sucrose accumulation and growth in various plant species. However, its effects on the dynamics of sucrose-metabolising and glycolytic enzymes in rice remain insufficiently explored. This study aimed to analyze the activities of sucrose metabolism enzymes, including SPS, invertases (acid and neutral), sucrose synthase (SuSy), and the glycolytic enzyme hexokinase (HXK) in transgenic rice plants overexpressing the SoSPS1 gene. The experiment was conducted using a completely randomized design with five genotypes, one of which was the wild type, and four transgenic rice lines, T4, T6, T8, and T9, with four replicates. The results showed that overexpression of the SoSPS1 gene led to significant increases in plant height and biomass, as well as markedly enhanced SPS activity in all transgenic rice plants compared to the wild type. Invertase activity (A-INV and N-INV) did not differ significantly among genotypes. In contrast, SuSy activity increased dramatically in transgenic lines T6, T8, and T9, suggesting that sucrose degradation in response to the genetic modification is primarily regulated through SuSy. The increase in SuSy activity was accompanied by the rise in HXK activity in the same lines (T6, T8, and T9). These results indicate that HXK subsequently phosphorylate hexose sugars, which may act as substrates for cellulose synthesis and activate the transcription factors that lead to higher biomass production. Overall, this study demonstrates that overexpression of SoSPS1 influences carbon flux and sugar metabolism, providing deeper insights into the relationship among sucrose biosynthesis, sugar sensing, and biomass enhancement in transgenic rice.
