Abstract

Soil is a vital natural resource that plays a crucial role in sustaining life. In addition to serving as a medium for plant growth, a provider of essential resources, and a physical foundation, soil also functions as an integral component of ecosystems. Degradation of soil functions may lead to ecosystem disturbances. The road section in Tosa Urban Village, East Tidore District, frequently experiences landslides during the rainy season. This road serves as a critical transportation route for the local community, supporting daily activities such as education, economic transactions, social interactions, and cultural events. Several segments of the road are characterized by steep slopes, which increase the potential for landslides, particularly during periods of high rainfall. Laboratory testing of soil samples from the Tosa area indicated a California Bearing Ratio (CBR) value of 5.77%, a maximum moisture content of 20.5%, and a maximum dry density of 1.73 g/cm³, reflecting very low bearing capacity. Grain size analysis showed that the natural soil consists predominantly of silt–clay materials, with more than 35% passing the No. 200 sieve, classifying it as A-7 soil according to the AASHTO system. The percentage passing the No. 200 sieve reached 108.77% for samples 1–3, exceeding the minimum classification requirement. The plasticity index was recorded at 14.91%. Atterberg limits testing further classified the soil as A-7-6, with a liquid limit exceeding 41% and a plasticity index greater than 11%. Specific gravity tests revealed that soil samples 1 and 2 are classified as humus soils, while sample 3 is identified as organic silt. Based on these findings, appropriate landslide mitigation measures for locations 1–3 include slope cutting, soil anchoring, and drainage system installation.

Abstract

Research on local food systems has often overlooked the comprehensive dynamics of household perceptions, particularly in archipelagic regions characterized by high levels of food vulnerability. This study aimed to examine the determinants of household perceptions and acceptance of sago (Metroxylon sagu) as a local staple food substitute in Tidore, Indonesia. A quantitative approach was employed through a survey of 88 households selected using proportional random sampling from a population of 728 households. Data were collected using a structured Likert-scale questionnaire and analysed using descriptive statistics, perception index analysis, and multiple linear regression. The findings revealed that household perceptions of sago were generally high, as reflected by the accessibility and availability index (76.74), nutrition and health awareness index (87.84), social acceptance index (88.18), and economic value and food security index (85.97). Multiple regression analysis indicated that age (B = 2.31, p = 0.021), education (B = 3.59, p < 0.001), and household size (B = 5.19, p < 0.001) had positive and statistically significant effects on household perceptions of sago. In contrast, household income showed no significant effect (B = −1.97, p = 0.11), while the model explained 54.7% of the variance in household perceptions (R² = 0.547). These findings provide empirical evidence that sago represents a strategic local food resource for strengthening food security in archipelagic regions. The study highlights the need for local governments to formulate integrated food diversification policies and promote value-added processing of sago-based products to reduce dependence on imported staple foods.
