The volume of Indonesia's sugar imports in 2019 reached 4,09 million tons. The high volume of imports was influenced by the decreasing area of sugarcane plantations. Lamongan Regency is one of the ...sugarcane and sugar-producing regencies in East Java. Sugarcane and sugar production in Lamongan Regency has experienced quite diverse dynamics and has been influenced by changes in land-use conditions. This study aims to analyze the balance of land needs for sugarcane plantations in Lamongan Regency in 2031 based on an analysis of land-use changes using SPOT imagery of 2007, 2013, and 2019. The study was conducted by analyzing land-use changes, population projections, and land demand balance analysis for sugarcane plantations. The results of the analysis showed that the population of Lamongan Regency in 2031 is projected to reach 1.419.843 people with a land requirement for sugarcane plantations of 2.362,29 ha. There will be a land surplus of 1.276,92 ha but it is still concentrated in 7 of the 27 sub-districts. Sugarcane plantations in Lamongan Regency have the potential to be developed considering that the land allocation for plantations in the Lamongan Regency Spatial Plan of 2011-2031 reaches 10.022,42 ha.
Vegetation can be an important indicator of ecosystem change, the influence of anthropogenic and non-anthropogenic factors. Therefore, it is important to study the dynamics of vegetation changes. One ...technique that can be used for vegetation analysis is the Normalized Difference Vegetation Index (NDVI). NDVI is an indicator of the active biomass that helps distinguish vegetation from other land cover and can provide information about changes in Spatio-temporal vegetation dynamics, thus allowing for assessment of the ecological conditions. This study aimed to investigate the dynamic of vegetation in the Sangkub watershed area located in North Sulawesi Province. This analysis used geospatial technology with the NDVI method, utilizing Landsat 5 and Landsat 8 satellite imagery data in three periods the year 2000, 2015, and 2020. The results showed that vegetation cover of the Sangkub watershed decreased substantially, whereas the non-vegetated area increased gradually over time.
This study aims to describe and analyze the challenges of teachers in building the nationalism character in the millennial generation in the digital era and strategies faced by teachers in building ...the nationalism character of students in formal education in the digital era. This study uses a qualitative approach using library research methods. Data collection technique with document study, and data analysis used is content analysis. The results of the study indicate that the challenges of teachers in Indonesia in building the nationalism character of the millennial generation are that they have not mastered competencies as educators (pedagogic, professional, social, and personality) to the maximum and have not been able to implement various learning methods and have not been optimal in utilizing digital-based learning media. The teacher's strategy in building the nationalism character of the millennial generation in the digital era is that the teacher must be able to master competencies as an educator, prepare effective learning tools, and implement various learning methods to utilize digital-based learning media. The development of technology is a challenge for teachers in building the nationalism character, so teachers must be able to adapt to the times and always improve their competence.
The Musi Hydropower-Plant catchment area is susceptible to soil erosion and sedimentation. Therefore, this research aimed to predict land use and land cover changes (LULCC) as well as their impact on ...soil erosion and sedimentation in the Musi Hydropower-Plant catchment area. The prediction of LULCC was calculated using Land Change Modeler module on IDRISI Terrset, while soil erosion and sedimentation were estimated with the Revised Universal Soil Loss Equation (RUSLE) and Sediment Delivery Ratio (SDR) models. The result showed that forest cover and paddy fields decreased significantly from 18.580 ha and 4.044 ha to 12.907 ha and 2.019 ha, respectively, in the periods of 1993 to 2019 and were predicted to reduce until 2032. Meanwhile, the built-up area and dry agricultural land increased from 818 ha and 2.116 ha in 1993 to 2.229 ha and 5.778 ha in 2019, which is expected to increase until 2032. The estimation of soil erosion rate also gave an increase from 75 t/ha/year to 113 t/ha/year, continuing to reach 122 t/ha/year until 2032. The escalation of soil erosion rate contributed to the change of sediment yield from 68.048 t/year in 1993 to 103.190 t/year in 2019,which is estimated to reach 111.028 t/year. These results are expected to be used by decision-makers and policymakers for the operation of the Musi Hydropower-Plant and the catchment area maintenance.
Lamongan Regency is one of Indonesia’s regencies in Indonesia that contribute to the country’s sugarcane and sugar production. Land-use/land-cover changes (LULC) have happened in various areas, ...including Lamongan Regency in East Java, Indonesia. This study aimed to analyze the impact of land-use/land-cover change (LULCC) in 2007–2031 on the sugar balance in the Lamongan Regency in 2031. The LULC forecast in 2031 was made using R studio using the CLUE-s function in the LULCC package. Following that, the sugar requirements and sugar balance in Lamongan Regency in 2031 were forecasts. The kappa accuracy of the LULC model tested in 2019 was 0.81 when using the CLUE-s model in R studio’s LULCC package. The findings of the LULC prediction in Lamongan Regency for 2031 indicated that there could be significant changes in LULC, resulting in an estimated reduction in 1,687.5 ha sugarcane, influenced by LULC competition for built-up areas. The Built-up areas in Lamongan Regency have exploded in size as a result of population. An increase in built-up areas and a reduction in sugarcane plantations as a result of LULCC are expected to diminish the sugar balance in Lamongan Regency by 10,470.76 tons in 2031 when compared to 2019. The results of this study can be utilized to prevent uncontrolled LULCC in the future to meet sugar needs in Lamongan Regency and at the national level.

The settlement growth is potentially increased by the rural-to-urban perspective change due to the new era of aerotropolis in Kulon Progo. Land-use planning evaluation is required, especially ...settlement, which has a significant impact on the environment. However, land-use evaluation studies are currently focused on conforming analysis of official land-use planning (OLUP) toward existing or predicted land use partially or in combination with the performance assessment unit. Consequently, it affects the quality of policy products by disregarding crucial considerations of diverse conditions at points of time and aspects of ideality, reality, and regulation. Therefore, the objective of this study was to design a comprehensive policy allocation for settlements using a matrix allocation rule that integrates conformity and performance analysis in three aspects of planning simultaneously. Land allocation was proposed using a geographic information system (GIS) of land capability, settlement suitability, and agricultural and forest land protection. The current land use/land cover (LULC) was classified using visual interpretation of SPOT 7 satellite imagery and a multi-layer perceptron neural network (MLPNN) to predict the LULC in 2035. The result indicated that the stock of land allocation for settlement development is sufficient to meet the demands in 2035. However, there is a problem in the settlement distribution pattern in which 64.3% of existing settlements are located in non-recommended allocation. That number is predicted to increase by 1,145.8 ha. Land-use control instruments need to be conducted to prevent extensive settlement growth in non-recommended allocation. Conversely, zoning allocation should be directed to trigger the growth of settlements in recommended allocation.
