Abstract

Disaster risk reduction (DRR) by taking into account the spatial planning in its implementation is not easy, for the Moluccas which has the characteristics of the region that has many cluster islands, and the accessibility are still low. Thus it requires special handling in the island-based disaster risk reduction, which will certainly be different from disaster risk reduction efforts that were undertaken in the continental region. The purpose of this research is to design the spatial area of the island cluster in Moluccas Province based on disaster risk. The method used is literature through spatial analysis of island risk-based groups. Based on the results of disaster risk assessment by the BPBD of Moluccas Province, it has been obtained that there are islands based on disaster risk (RB-islands cluster). The high disaster risk level was the island cluster on RB III and IX, the medium disaster risk level was the island cluster on RB I, IV, VI, and VIII, the low disaster risk level was the island cluster on RB II, V, and VII. The RB island cluster is a model for reaching areas with high disaster risk, can easily identify what causes it. It become an input to mitigate it through the spatial arrangements for achieving a sustainable archipelago development. The regional spatial arrangements aimed at reducing disaster risk in the RB-islands cluster in the Moluccas through spatial planning, structural handling/civil engineering, education, and community empowerment.

Abstract

The difficulty of the inventory carried out in the mangrove forest area is due to the vast expanse of ​​mangrove forests with a high-density level, so it must use High-Resolution Satellite Imagery (CSRT) which requires high costs. The approach to processing very high-resolution images is the object-based approach (OBIA). UAV technology development using cameras mounted on UAVs has been widely used in forest inventories that have benefits, low costs, and high flexibility. Therefore, this study aims to analyze the types of mangroves using UAV images with OBIA classification and calculate the tree canopy height model in mangrove forests. The results showed that the accuracy-test used a confusion matrix with Producer accuracy for BG 78%, CT 97%, RS 96.63%, RA 91.04%. In comparison, the user accuracy for BG is 88.89%, CT 97.73%, RS 97.73%, and RA 85%. Thus the overall efficiency is 92.98%.

Abstract

Research on Land Evaluation for Residential Development in the Telaga Kodok Hamlet area has been conducted with the aim of determining the suitability classes of residential land and identifying limiting factors. The land characteristics studied include slope, effective depth, flooding and ponding, drainage, rock, and soil texture. The weight of each characteristic was analyzed using the Analytic Hierarchy Process (AHP). The analysis results indicate that there are 112.07 hectares (29.94%) of highly suitable residential zones, 166.67 hectares (44.53%) of moderately suitable zones with limiting factors such as moderate depth, poor drainage, and fine texture; 92.03 hectares (24.59%) of marginally suitable residential zones with limiting factors like steep slopes and fine texture; and 3.55 hectares (0.94%) of zones unsuitable for residential development.

Abstract

The research examined the effect of ela sago compost on the soil chemical properties, growth, P-uptake, and yields of corn plants (Zea mays L) in Regosol soils. A randomized block design with a 2 x 4 factorial treatment was applied. The first factor was ela sago compost (B) with three dose levels: B0 = 0-Mg ha-1, B1 = 10-Mg ha-1, and B2 = 20-Mg ha-1. The second factor was SP-36 (P) fertilizer with four dose levels: P0 = 0 kg P ha-1, P1 = 60 kg P ha-1, P2 = 120 kg P ha-1, and P3 = 180 kg P ha-1. This research shows that either ela sago compost or SP-36 fertilizer can increase the soil reaction (pH). Applying sago palm compost and SP-36 fertilizer increases soil available P from 17.33 to 60.67 ppm. Applying sago palm compost and SP-36 fertilizer increases plant P-uptake from 0.18 to 0.40 %, plant height from 135.60 to 189.67 cm, and stem diameter from 1.86 to 3.44 cm, and corn yield (dry weight of 1000 seeds) from 266.60 to 390.57 g.

Abstract

Research on rock resistivity and slip surface in the Ambon Volcanic Rock formation has been carried out through geoelectric mapping with the Wenner-Schlumberger configuration in the Kayu Putih area, Ambon City as one of the areas prone to landslides. Measurement of rock resistivity by Mapping was carried out on two tracks each 120 m long and 70 m long intersecting each other. The results showed that the resistivity values ​​of the rocks ranged from 185 Ωm to 4,128 Ωm consisting of Top Soil, Unsaturated Landfill, and Loose Sand as the cover layer followed by Dry Sandy Soil and Gravel, and Breccia Dacite and Tuff at the bottom layer. Breccia Dacite rocks with a resistivity of greater than 2,000 Ωm are found at a depth of 11 – 13 m below the soil surface functioning as slip surface for the sand layer above them. The movement of the soil mass over the slip surface causes cracks in the surface of the road and houses.
