Abstract

This study aims to identify the development of settlements in the Amurang Timur District. The method used is quantitative research—data collection techniques in the form of observation, documentation, and remote sensing. Researchers use GIS analysis techniques on Landsat 7 and Landsat 8 images. The results of the study show that the development of settlements in Amurang Timur District is influenced by population growth from 2015-2022, there was an increase in settlements of 92.49 hectares. The exponential population growth rate in 2015-2022 was 1.55%.

Abstract

This study aims to evaluate the effect of applying the Storytelling learning method on students' conceptual understanding of Population Dynamics material in class XI SMAN 3 Tondano. The research method used is descriptive research with a quantitative approach. During the learning process, students are divided into small groups to discuss the material, and then convey the results of their discussions through stories related to geographic concepts. The results showed that the majority of groups scored high in the aspects of content truth, fluency, intonation, and clarity. The average score was 4 for content truth, fluency, and clarity, and 3 for intonation, which shows that the Storytelling method effectively improves conceptual understanding and speaking skills. In addition, students also showed increased self-confidence and active involvement in the learning process.

Abstract

This study aims to determine, analyze, and describe the waste transportation system and the factors that influence the implementation of policies on waste management by reviewing several indicators, namely household waste sorting, waste transportation to the SPA (Intermediate Transition Station) by garbage motorbikes, then continued to the TPA (Final Disposal Site) by garbage trucks, and also the timeliness of waste transportation. The research method used is a descriptive method with a qualitative approach using primary and secondary data obtained through interviews, observations, and documentation. The results of this study indicate that good waste management can support the optimization of the waste transportation process. The implementation of waste management policies on the transportation system still encounters various obstacles, such as a lack of public awareness in sorting waste, a lack of transportation fleets, delays in transportation, and a lack of maximum supervision. These obstacles cause the waste transportation system to not run optimally. In addition, the implementation of policies in waste management greatly affects the smoothness and optimization of the waste transportation system, so there is a need for improved facilities and infrastructure, community participation, and more intensive supervision so that the waste transportation system can run well, more effectively, efficiently, and sustainably.

Abstract

Abstract This study aims to analyze the implementation of waste management in Bitung City based on Regional Regulation Number 17 of 2013 and identify the factors that influence it. This study uses a descriptive qualitative approach with the Miles and Huberman interactive analysis model. Data were collected through in-depth interviews, field observations, and documentation. Informants consisted of officials and staff of the Bitung City Environmental Service, village/district officials, cleaning staff/waste collectors, and the community. The results of the study indicate that the implementation of waste management is not optimal in three main indicators: (1) Waste sorting is still very limited because the community is not used to it, supporting facilities are not available, and the perception is that sorted waste will be mixed again during transportation; (2) Waste collection faces problems with the availability of very limited TPS (landfills), the condition of the TPS does not meet the standards of being closed, neat, and odorless, and the collection mechanism is not systematic; (3) Waste transportation is disrupted because the fleet is often damaged due to lack of routine maintenance, reactive (emergency) maintenance, uneven schedules and routes, and the absence of a special fleet for sorted waste so that sorted waste is mixed again. Factors that influence implementation include internal bureaucratic factors (limited personnel, poor fleet maintenance, weak coordination), social and cultural factors (habits of littering, sorting not yet a culture, weak social sanctions), as well as policy and institutional factors (weak enforcement of sanctions, no special institutions at the sub-district level, budget limitations).

Abstract

Lake Tondano has experienced uncontrolled water hyacinth growth, which has negatively affected water quality and aquatic ecosystems. This study aimed to analyze the distribution and density of water hyacinth and its relationship with environmental factors, particularly wind direction and nutrient availability. The study was conducted using a quantitative descriptive approach with the NDVI method based on multi-temporal Sentinel-2A satellite imagery from 2023 to 2025. The results show that the area of water hyacinth fluctuates over time, covering 324.58 ha in April 2023, decreasing in September, increasing again in October, and reaching the highest extent of 371.82 ha in April 2024, while the lowest area of 205.94 ha occurs in October 2024. Spatially, a distribution shift occurs in 2023, whereas a relatively stable pattern with dominance in the eastern part of Lake Tondano is observed during 2024–2025. These patterns indicate that dominant wind direction and nutrient availability play important roles in controlling the spatial dynamics of water hyacinth in Lake Tondano
