Abstract

Salah satu dari tujuan UU No. 4/2011 tentang Informasi Geospasial adalah untuk meningkatkan pertumbuhan ekonomi yang berbasis pemerataan dan keberlanjutan. Pemerataan selain berdimensi sosio-demografis juga geografis-finansial. Dan keberlanjutan selain memperhatikan aspek ketersediaan sumber daya alam juga dampak lingkungan. Tulisan singkat ini akan membahas 3 aspek dari sekian aspek ekonomi geospasial di Indonesia. Pertama menelaah gagasan bahwa bila Informasi Geospasial Dasar (IGD) yang menjadi domain Badan Informasi Geospasial (BIG) digratiskan, maka akan terjadi dampak positif ekonomi yang cukup signifikan, dan berbagai cabang ekonomi kreatif spasial akan tumbuh subur. Kedua menelaah aspek-aspek penguatan SDM yang diperlukan untuk menunjang tumbuhnya ekonomi geospasial. Dan ketiga ide pengaturan agar masyarakat tetap mendapatkan IGDyang paling berkualitas, di tengah keterbatasan sumberdaya BIG – meski mendapat mandat UU menjadi satu-satunya penyelenggara, namun pada saat yang sama ada inisiatif baik dari pemerintah daerah, swasta maupun masyarakat.Kata Kunci : Informasi Geospasial, Ekonomi, Tarif Gratis, Pemetaan Partisipatif.ABSTRACTOne of the purposes of Law No. 4/2011 on Geospatial Information is to increase economic growth based on equity and sustainability. Equalization in addition to socio-demographic dimension is also geographically-financial. And sustainability in addition to the aspect of the availability of natural resources also impacts to the environment. This short article will discuss three aspects of the geospatial aspects of Indonesias economy. The first examines the idea that if the Base Geospatial Information (IGD) which is the domain of the Geospatial Information Agency (BIG) is free, there will be a quite significant positive economic impact, and the various branches of creative spatial economy will flourish. The second examines aspects of strengthening human resources needed to support the geospatial economic growth. And the third idea is regulating so that people still get the most qualified geospatial information, among constraints of BIG - although received a legal mandate to be the sole provider, but at the same time there is a good initiative from the local government, private and public.Keywords : Geospatial Information, Economic, Free Charge, Patisipatory Mapping.

Abstract

Dalam studi ini data multi temporal satelit Landsat resolusi spasial 30 meter periodetahun 2003, 2006 dan 2009 dan data MODIS tahun 2003 dan 2008 digunakan untuk deteksi degradasi hutan wilayah Kalimantan, khususnya Kalimantan Timur. Deteksi level degradasi hutan menggunakan metode deteksi perubahan (change detection) dan analisa fragmentasi (fragmentation analysis). Kategori fragmentasi ditentukan berdasar pengelompokkan hutan dengan klas edge, perforated dan patch, sementara hutan alami dikelompokkan atas dalam hutan core pada buffer 250 sampai 500 acre. Selanjutnya dilakukan analisa faktor dasar (baseline factor) untuk memahami penerapan REDD sebagai respon terjadinya degradasi hutan. Hasil analisa data MODIS 2003-2008 menunjukkan terjadinya kecenderungan perubahan penurunan luas hutan sebesar 23,5% (7.256.931 ha). Dari 23,5% tersebut, sekitar 70,0% (5.089.851,7 ha) berupa perubahan penurunan pada hutan alami dan sekitar30,0% (2.167.079,3 ha) berupa penambahan hutan yang terkategori degradasi. Sebaliknya terjadi pula penambahan pada areal bukan hutan sekitar 30% (2.167.079,3 ha). Sementara analisa dengan data Landsat menunjukkan hasil kebalikan, yaitu selama periode 2003 – 2009 terjadi kenaikan jumlah hutan alami sebesar 3,5% (961.313 ha). Dari jumlah 3,5% tersebut, sebesar 7,8% (1.519.694 ha) berupa penambahan pada luasan hutan alami, dan berupa penurunan hutan terkategori degradasi sebesar 6,8% (558.381 ha) dan penurunan atas area bukan hutan sebesar 3,7% (961.313 ha). Adaptasi REDD pada masyarakat Kalimantan timur tersebar pada kelompok hutan terdegradasi (Patch, Perforated dan Edge). Kata Kunci: Hutan Tropis Basah, MODIS, Landsat, REDD, Hutan TerdegradasiABSTRACTSThis study used multi-temporal satellite Landsat imageries with 30-meter spatialresolution period in 2003, 2006 and 2009 and MODIS data in 2003 and 2008 for detection of forest degradation in Kalimantan region, especially East Kalimantan. Detection of degradation level was done using change detection method and fragmentation analysis. Categories were determined by grouping of forest fragmentation by class of edge, perforated and patches, while natural forests in the forest cores were grouped on the buffer 250 to 500 acres. Further analysis was conducted on baseline factors to understand the application of REDD as a response to forest degradation. Analysis result of MODIS data in 2003-2008 shows a trend of decreased forest area by 23.5% (7,256,931 ha). Of 23.5%, approximately 70.0% (11,793,319 ha) were in the form of changes to a decrease in natural forest and approximately 30.0% (4,536,388 ha) of forests are categorized addition of degradation. In contrast, there were also addition to non-forest area of about 30% (7,252,525 ha). Meanwhile, Landsat data analysis shows the opposite result. For example, during the period 2003 – 2009 there was an increase of 3.5% (961,313 ha) of natural forests. Out of the total 3.5% of these, 7.8% (1,519,694 ha) were in the form of addition to the natural forest area, and a decrease in forest degradation as many as 6.8% (558,381 ha) and a decrease of nonforest area of 3.7% (961,313 ha). Adaptation of REDD in East Kalimantan communities scattered in groups of degraded forests (Patch, Perforated and Edge).Keywords: Tropical Rain Forest, MODIS, Landsat, REDD, Degraded Forest

Abstract

Ancaman banjir pada lahan sawah dapat menyebabkan berkurangnya luas panen dan produksi beras. Banjir genangan di wilayah pantura Jawa Tengah ini disebabkan oleh tingginya curah hujan dan/atau pasang air laut (rob). Penelitian ini dilakukan untuk mengetahui persepsi petani terhadap banjir genangan pada lahan sawah. Persepsi masyarakat petani yang digali mencakup persepsi mengenai kejadian banjir pada lahan sawah baik yang disebabkan karena hujan atau rob, atau gabungan antara keduanya, dan dampaknya terhadap produksi padi. Persepsi petani merupakan dasar perilaku adaptasi yang dilakukan petani. Adaptasi mencakup segala usaha yang dilakukan sebagai upaya untuk mengurangi risiko, dari risiko pengurangan produksi padi hingga hilangnya seluruh lahan sawah karena tergenang secara permanen. Penelitian ini dilakukan dengan melakukan observasi lapangan dan wawancara, dengan sampel terpilih dan terbatas pada petani di wilayah yang terkena banjir. Hasil dari penelitian ini menunjukkan bahwa petani di wilayah penelitian telah melakukan adaptasi guna mengurangi risiko kerugian karena banjir sesuai dengan persepsi dan kapasitasnya yang diwujudkan dalam pembangunan infrastruktur penahan banjir dan/atau modifikasi bentuk pola tanam.Kata Kunci: Sawah, Banjir Genangan, Persepsi ABSTRACTFlood inundation over the paddy field threatens the rice production by degrading the harvest area and rice production. Flood inundation in the area of study occurs due to high rainfall and/or sea water tide. This research aims to study farmers’ perception towards the flood inundation over the paddy field. Farmers’ perception investigated includes perception towards the occurrences of flood inundation resulted from rainfall and/or sea water tide and the impact to the rice production. The farmers’ perception is the based of farmers adaptation behaviour. Meanwhile, the adaptation investigated includes any efforts that have been carried out to reduce the risks, from the reduction of rice production into the lost of paddy field due permanent inundation. This research carried out by doing field observation and interview, with sample selected purposively inclusively to farmers in the flooded area. The result shows that the farmers have been performed adaptation based on their perception and capacity by building flood control and modification of crop calendars.Keyword: Paddy Field, Flood Inundation, Perception

Abstract

This study uses Random Forest model and statistical analysis to evaluate the relationship between the Index of State Defense (IBNu) and the Human Development Index (HDI) at the provincial level in Indonesia. The data includes the average IBNu, HDI in 2023, the manager's prediction, and data from the Indonesian Democracy Index (IDI) in 2021-2023. The model shows excellent prediction performance with a Mean Squared Error (MSE) of 0.0018 and an R² value of 0.97, indicating that the prediction results are very close to the actual data. The residual plot also shows that the model has no significant bias as the prediction error is evenly distributed around the zero line. Correlation analysis found that HDI has a strong positive correlation with education variables, such as Expected Years of Schooling and Average Years of Schooling, while IBNu is negatively correlated with economic growth, indicating that an increase in IBNu may have the effect of decreasing economic growth. The classification performance of the model was assessed using the confusion matrix, which showed accuracy, precision, recall, and F1 scores of 0.8, indicating the model's ability to distinguish between the various classes well. These results suggest that IBNu policies aimed at improving HDI may not always be effective and that a more comprehensive policy approach is needed. The proposed recommendations include the integration of national defense and human development programs into the school curriculum, balanced budget allocation, innovative programs for the community, support for the balance between security and welfare, and continuous research and evaluation.

Abstract

The location of cross-border posts is crucial for Indonesia's land and maritime security and combating illegal activity. Geographical intelligence technology like sensors and machine learning can help find crucial sites. GEOINT and international cooperation enable monitoring, threat detection, and trade regulation. This study uses a literature review to examine how GEOINT helps Indonesia defend its territory. This research collects, analyzes, and synthesizes important scientific studies using a literature review. Our literature search used relevant terms in scientific databases. The selected literature covers GIS, GEOINT, Satellites, Drones, and cross-border posts. Analysis identified major conclusions and research gaps. Geospatial intelligence technology (GEOINT), which uses drones and satellites to monitor and provide high-resolution data, is effective at detecting and responding to threats in Indonesia's extensive border areas. Additionally, this technology helps find the right cross-border post. Geographic information systems (GIS) must assist centralized data management and defense agency collaboration to strengthen border security. GEOINT supports strategic cross-border post placement decisions to secure Indonesia's borders. For regional defense, national security, and stability in the face of complex global problems, the latest and most effective technologies must be developed and used.
