Abstract

In Indonesia, onion cultivation uses bulbs, which disrupts stocks of consumtion and trade quite significantly. One way to reduce the need for bulbs from onions is to use True Shallot Seed (TSS). Onion of TSS can reduce production costs, and is practical in shipping compared to bulbs. One of the activities in the cultivation of TSS is the preparation of strong, uniform and healthy of seedling. This study aims to examine the appropriate composition of organic matter as a planting medium to accelerate the germination time of various cultivars of TSS. The planting medium tested was a mixture of soil, rice husk, cocopeat and sawdust. This study used a complete randomized block design which was arranged in factorials. The first factor was the variety and the second factor was mixing of organic matter. Mixing organic matter with the soil before planting onion seeds led to an increase in soil pH from 0.77 to 1.51. Mixing soil with organic matter before implementation increased the pH of the media, CEC, WHC, and decreases the bulb density. After germination, the husk and cocopeat mixture showed a pH (5.9), CEC (1.62 mS.cm-1), bulb density (0.3 g/cm3) and WHC (162%). The combination of rice husk and cocopeat as the growing medium (4,9 days), the Sanren cultivar (7,3 days) exhibited the fastest germination and seedling growth rate compared to other cultivars and mixed growing media.

Abstract

The study of rice seedling resistance due to seed priming and seeding density under submergence stress condition was carried out to evaluate the effect of seed priming and also to estimate proper seeding population density to improve rice seedlings vigor under submergence stress condition. The เว็บสล็อต | R4shub experiment was conducted in tidal freshwater swamp of Sako in Rambutan District, Banyuasin Regency (3.067° S, 104.8616° E). Randomized block design was used where the seeds were soaked into ZnSO4.7H2O solution as priming treatment, and then sown with three different seeding rates: 30, 40 and 50 kg ha-1. Three cultivars consisted of Inpara 3, Inpara 5 and Ciherang were tested. The observation was carried out until 4 weeks after sowing to measure the seedling height, shoot dry weight, carbohydrate content in stem, and leaf chlorophyll. Results showed that all treatments indicated insignificant effect to all parameters. However, the highest result from all parameters was obtained from priming treatment. The higher seeding density the lower dry weight, carbohydrate and chlorophyll content. All three tested cultivars, Inpara 3 gave the best performance.

Abstract

This study aims to analyze the dynamics of land cover changes in North Musi Rawas Regency in the period 2017–2023 and triggers for flood risk using remote sensing and Geographic Information Systems (GIS) approaches. The research methods include Sentinel-2 satellite imagery classification using supervised classification techniques, accuracy validation, and spatial-temporal analysis to identify land conversion patterns and their relationship to hydrological dynamics. The results of the analysis show significant conversion of agricultural land vegetation (9,769 ha), built-up land (194 ha), shrubs (15,011 ha), and swamps (514.17 ha), which are driven by urbanization factors, expansion of the agricultural sector, and environmental degradation. These changes contribute to increased flood risk, with the area affected by the medium risk category reaching 133,586 ha, especially in Karang Dapo, Rupit, and Rawas Ilir Districts, while the low-risk area covers 31,397 ha. Meanwhile, areas with better vegetation cover show higher flood mitigation capacity. This study confirms that changes in land cover have a close correlation with increased flood risk, so that land management policies based on spatial data and the use of remote sensing technology are needed to support disaster mitigation and adaptation strategies more effectively
