Kendari City is characterized by varied geomorphological conditions such as hills, alluvial plains, river valleys, and coastal areas that contribute to hydro-meteorological and geological disaster risks. However, understanding and awareness of disaster mitigation among elementary school students remain limited. This community service project aims to improve students’ knowledge of landform characteristics and their relation to disaster potential, as well as to equip them with practical mitigation skills. The program consisted of preparation, implementation, and evaluation stages, involving 22 participants from SDN 101 Kendari. Activities included focus group discussions, interactive education on geomorphological concepts, poster-making, disaster card games, and simulations of earthquakes, floods, and landslides. Results show an increase in students’ understanding and alertness, reflected in their ability to identify disaster-prone landforms and perform mitigation actions practiced during simulations. Teachers also showed increased motivation to integrate disaster education into classroom learning. This program effectively fosters disaster awareness in early education and can be developed into a sustainable school-based program.

Digital technology-based mapping in development planning is often unable to capture the dynamics of land use change at the micro scale. Therefore, the integration of spatio-temporal participatory mapping with digital data through overlay analysis is important to produce more accurate, contextual, and inclusive land use change information. This study aims to 1) classify land use types in Lainea District, South Konawe Regency, and 2) analyze land use changes spatio-temporally from 2016 to 2025, to determine the direction of development based on mapping with the community. This study uses terrestrial survey methods and digital survey collaboration using remote sensing data from Landsat-8 and Landsat-9 images. The results show that in the period 2016 to 2025 there was a significant change of 1,411.28 ha. The largest decrease occurred in mixed dryland agricultural land which shrank by 583.85 ha (41.37%) of the total change, followed by swamp scrubland covering -13.84 ha. In contrast, there was a significant increase in rice fields, reaching 528.89 ha (37.45%), and secondary dryland forest, reaching 103.60 ha. Residential and mining areas also increased, although by relatively small percentages. Overall, this trend indicates a shift in land use from shrubland and mixed agriculture to more intensive uses such as rice fields and secondary forests.

This study aims to describe students' errors in solving mathematics problems based on their conceptual understanding. This research employed a descriptive qualitative approach involving 28 eighth-grade students from SMP Negeri 1 Latambaga. Data were collected using a conceptual understanding test, designed based on several indicators (classifying objects according to their properties, giving examples and non-examples of a concept, applying concepts algorithmically, and presenting concepts in various representative forms). Student errors were analyzed using Nolting's theory, which categorizes errors into careless, concept, application, and test procedure errors. The instrument was validated by mathematics education experts and teachers, and tested for item validity. After the test, four students representing different ability levels (high, medium, low, very low) were selected for interviews. The results showed that, in general, students' conceptual understanding was low. The most dominant errors were concept and application errors, while procedural and careless errors also appeared but less frequently. In conclusion, students' errors are primarily caused by weak conceptual understanding and a lack of systematic problem-solving abilities.

Higher-order thinking skills (HOTS) are essential in fostering students' critical and creative problem-solving abilities, particularly in mathematics. This study aims to determine the level of difficulty students face in solving HOTS-based mathematics problems. This qualitative descriptive study was conducted at SMPN 1 Latambaga with 23 eighth-grade students (class VIII A) as participants. The instruments, comprising tests and interviews, were constructed based on three indicators of HOTS: analyzing, evaluating, and creating. From the participants, six students were selected to represent three ability levels: high, moderate, and low. Students in the high category met all HOTS indicators. Moderate-level students achieved analyzing and evaluating but struggled with the creating aspect. Low-level students were only able to analyze and faced difficulties in evaluating and creating solutions. Their challenges included misapplication of principles, procedural errors, and verbal misunderstandings of question instructions. The findings highlight the need for targeted strategies to enhance students' critical and creative thinking in solving contextual and open-ended mathematics problems.

Mangrove ecosystems play a crucial role in maintaining coastal environmental stability, requiring accurate spatial information on their distribution, density, and canopy cover conditions. This study aims to assess the extent and spatial distribution of mangrove ecosystems, vegetation density levels, canopy cover conditions, and the relationship between Normalized Difference Vegetation Index (NDVI) values and mangrove canopy cover percentages in the coastal area of Kendari City. Mangrove distribution and density were analyzed using Sentinel-2A imagery through the NDVI approach, while canopy cover was measured using the Hemispherical Photography method processed with ImageJ software. Satellite imagery was obtained from the Copernicus platform, and a total of 33 sampling stations or plots were determined based on mangrove density classification criteria. The results indicate that the total mangrove area along the coast of Kendari City is approximately 275.67 hectares, distributed across eight sub-districts. NDVI analysis classified mangrove vegetation into three density categories: low density covering 30.69 ha, medium density covering 68.28 ha, and high density covering 176.70 ha. Mangrove canopy cover varied in accordance with vegetation density, ranging from 16.56% to a maximum of 88.08%. Correlation analysis revealed a very strong relationship between NDVI values and canopy cover percentage, with a correlation coefficient (r) of 0.93. These findings demonstrate that Sentinel-2A-derived NDVI is a reliable indicator for estimating mangrove canopy cover conditions in coastal environments. ABSTRAKEkosistem mangrove memiliki peran penting dalam menjaga keseimbangan ekologi pesisir, sehingga diperlukan informasi spasial yang akurat terkait sebaran, kerapatan, dan kondisi tutupan tajuknya. Penelitian ini bertujuan untuk menganalisis luas dan distribusi ekosistem mangrove, tingkat kerapatan vegetasi, kondisi tutupan kanopi, serta hubungan antara nilai Normalized Difference Vegetation Index (NDVI) dan persentase tutupan tajuk mangrove di wilayah pesisir Kota Kendari. Analisis kerapatan dan sebaran mangrove dilakukan menggunakan citra Sentinel-2A melalui pendekatan NDVI, sedangkan tutupan kanopi dianalisis menggunakan metode Hemispherical Photography yang diolah dengan perangkat lunak ImageJ. Data citra diperoleh dari laman Copernicus, kemudian ditentukan sebanyak 33 stasiun atau plot sampel berdasarkan klasifikasi tingkat kerapatan mangrove. Hasil penelitian menunjukkan bahwa total luasan mangrove di pesisir Kota Kendari mencapai sekitar 275,67 hektar yang tersebar di delapan kecamatan. Berdasarkan nilai NDVI, ekosistem mangrove diklasifikasikan ke dalam tiga tingkat kerapatan, yaitu kerapatan rendah seluas 30,69 ha, kerapatan sedang 68,28 ha, dan kerapatan tinggi 176,70 ha. Persentase tutupan tajuk mangrove bervariasi mengikuti tingkat kerapatan vegetasi, dengan nilai tertinggi sebesar 88,08% dan terendah 16,56%. Analisis korelasi menunjukkan hubungan yang sangat kuat antara nilai NDVI dan persentase tutupan kanopi dengan koefisien korelasi (r) sebesar 0,93. Temuan ini menegaskan bahwa NDVI citra Sentinel-2A dapat digunakan secara efektif untuk menduga kondisi tutupan kanopi mangrove di wilayah pesisir.
