Abstract

Monitoring soil surface moisture is a crucial aspect of drought detection and management, significantly contributing to informed decision-making in agriculture and natural resource management. Remote sensing technologies have been widely applied to predict surface soil moisture. This study aimed to develop and analyze a surface soil moisture prediction model based on remote sensing data for drought mitigation. This research was conducted in the administrative area of Sleman Regency, Yogyakarta Special Region Province. This study employed a method that integrates field measurements with remote sensing-derived data to develop a predictive model of surface soil moisture. The model was constructed using the Extreme Gradient Boosting (XGBoost) machine learning algorithm. The modeling results yielded an R² value of 0.62 and an RMSE of 0.83. The model was then applied to generate spatial estimates of surface soil moisture for the period from May to October 2024. Spatially, all six months exhibited a consistent distribution pattern, with low soil moisture levels concentrated in the central southern part of the study area. The findings can serve as a basis for highlighting land management in line with SDG Goal 15, which aims to protect, restore, and enhance the sustainable use of terrestrial ecosystems, sustainably manage forests, halt and reverse land degradation, and halt biodiversity loss.

Abstract

Inappropriate land management system has emerged as a serious issue in agricultural development. Instead of boosting land productivity, suboptimal land use has become a viable option for regional agricultural development. However, this has not resulted in considerable increases in agricultural productivity. The purpose of this study was to improve soil parameters and increase watermelon (Citrullus vulgaris Schard) production by applying soil amendments to suboptimal land. This study was conducted utilizing a factorial randomized group design with two factors. The first factor was the application of mulch (M) with three treatment levels: M0 = no mulch, M1 = reed mulch, and M2 = coconut leaf mulch; the second factor was the application of bird manure fertilizer (P) with three treatment levels: P0 = no fertilizer, P1 = 10 t/ha fertilizer, and P2 = 20 t/ha. The data was analyzed using ANOVA and Duncan's multiple range test (significant at P < 0.05). The study was conducted at Khairun University's Campus IV in Madihutu Village, Kao Teluk District, North Halmahera Regency. Soil parameters and plant agronomic traits were among the observed variables. The findings revealed that the mulch and bird manure treatments had no significant impact on soil characteristics. In terms of plant agronomic features, the mulch-free treatment had the greatest impact on watermelon plant growth and yield, whereas the 10 t/ha fertilizer treatment outperformed the other treatments. Keywords: bird manure fertilizer, mulch, suboptimal land, watermelon plant

Abstract

Signs of soil that has undergone advanced development include clearer horizons, higher fine fraction and lower coarse fraction, brighter soil color, higher levels of free Al and Fe. Soil aggregation is increasing, to a certain extent organic matter and nutrient levels are increasing as well as CaCO levels, and soluble salts. Soil development is characterized by the occurrence of horizon differentiation as a representative of the process of change in the earth's skin both physically, chemically and biologically by reactions in the soil profile there is an addition of organic and mineral materials in the form of solid, liquid or gaseous materials, the disappearance of materials above the soil, the transfer of materials from one part to another in the soil body, the transfer of the form of mineral compounds and organic matter in the soil body This research was carried out in the village of Bobaneigo Madihutu, South Jailolo District, West Halmahera Regency from June to July 2023. The method used in data collection is a free survey method, which is an observation made directly in the field by determining the research location based on land use maps, and administrative maps. The variables observed were C-Organic, N-Total, C/N Ratio, CEC, KB which are soil chemical properties. The results showed that the study of the level of soil development in several types of land use has not experienced weathering or advanced development due to the low content of nutrients.

Abstract

Landslides and flash floods are common natural disasters in volcanic landscapes. The repercussions of these events are substantial. A dearth of understanding, preparedness, and awareness of disaster risks can result in casualties, significant material losses, and impediments to the post-disaster recovery process. Disaster mitigation has been demonstrated to be an effective solution for managing post-disaster activities. The objective of this service activity is to elucidate the significance of participatory-based disaster mitigation in establishing a community that is responsive to disasters. The activity was carried out in Rua Village, Ternate Island District, Ternate City. The community service method employed is characterized by a socialization approach, encompassing mentoring, monitoring, and evaluation. Activities are carried out directly in the community in Rua Village. The findings of the initiative have contributed to an enhanced understanding of disaster mitigation strategies, particularly within the context of volcanic landscapes, in regions susceptible to such events. Additionally, the team emphasized the importance of implementing initiatives such as afforestation, erecting disaster-response shelters, and strengthening community resilience. Furthermore, additional coordination is necessary between the community and the local government to effectively manage disaster-prone areas. These regions must be identified as priorities so that the local government can implement initiatives aimed at cultivating disaster-resilient communities.
