Abstract

Sedimen yang adapada suatu aliran sungai umumnya terjadi akibat proses erosi yang berkaitan erat dengan siklus hidrologi. Beberapa parameter erosi dan sedimen adalah curah hujan, vegetasi tutupan lahan, jenis tanah dan kemiringan tanah. Catchment Area Sungai Hauran memiliki kondisi vegetasi tutupan lahan berbeda pada tahun 2005 dan 2014. Oleh karena itu perlu dilakukan penentuan nilai erosi dan sedimen terkini serta menganalisa dampak perubahan tutupan lahan tahun 2005 dan 2014 terhadap besarnya erosi dan sedimen pada satu kejadian hujan dengan data hujan yang sama. Agricultural Non Point Source Pollution Model (AGNPS) adalah salah satu model terdistribusi yang dapat digunakan untuk menganalisa erosi dan sedimen dengan kejadian hujan tunggal. Pengolahan data menggunakan model AGNPS diperoleh besar erosi persatuan luas yang terjadi pada tahun 2014 sebesar 256,43 ton/ha/tahun menunjukkan tingkat erosi berat dan total sedimen sebesar 17947,79 ton/tahun (17,60 ton/ha/tahun) termasuk klasifikasi tingkat sedimen tinggi. Perbandingan tingkat erosi dan sedimen karena adanya perubahan tutupan lahan tahun 2005 dan 2014 dengan input hujan 18,2 mm mengalami peningkatan total erosi persatuan luas dari 1,93 ton/ha menjadi 11,46 ton/ha dan mengalami penurunan total sedimen pada tahun 2014 dari 50,7 ton menjadi 26,15 ton.

Abstract

Total Suspended Solid (TSS), as one of the physical parameters of water quality, can also become an indicator in more comprehensive research themes. TSS is closely related to the process of erosion and sedimentation. One of the reservoirs that is experiencing serious problems with sedimentation is WGM. In terms of physical changes, alterations in water quality involve the introduction of both organic and inorganic solid particles, leading to elevated water turbidity and diminished penetration of sunlight into the water body. Remote sensing techniques can indirectly estimate and map TSS in bodies of water. Landsat imagery has been widely used in TSS studies. Not only is it able to identify water turbidity, but it also has a long time series and convenient data accessibility. The purpose of this research is to examine the TSS equation in the form of Normalised Suspended Material Index (NSMI) and the Syarif Budhiman Algorithm to obtain a comparison of results that are suitable for application to the waters of WGM using Landsat imagery. The results showed that the Syarif Budhiman Algorithm is considered more suitable to be applied to the study site based on statistical analysis using Landsat image data and field TSS sample data. The accuracy test results for the two equations did not show significant differences. The Syarif Budhiman equation showed a value of 37.87, and the NSMI equation of 37.47. However, the coefficient of model determination was 0.251 for NSMI and 0.340 for Syarif Budhiman. The distribution of TSS at the study site is generally homogeneously distributed with small concentrations ranging from 0-20 mg/L in the middle side of the reservoir. While the TSS class > 100 mg/L is scattered on the edge of the reservoir in Pondok, Keduang, Kepuh Wiroko, Temon, Bengawan Solo Hulu, Alang, and Kedungguling sub-watersheds

Abstract

Penerapan prinsip rule of law di Indonesia masih menghadapi berbagai kendala, terutama pada level penegakan hukum yang bersentuhan langsung dengan masyarakat, seperti di kepolisian sektor (Polsek). Polsek Banjarsari sebagai ujung tombak pelayanan dan penegakan hukum memiliki peran penting dalam menjaga ketertiban, keamanan, serta konsistensi supremasi hukum. Namun, pelaksanaannya masih terhambat oleh keterbatasan personel dan sarana, kurang optimalnya kualitas layanan publik, serta potensi penyimpangan yang dapat mengganggu keadilan dan kepastian hukum. Kondisi ini menunjukkan perlunya peningkatan kinerja Polsek Banjarsari agar kontribusinya terhadap pembangunan hukum nasional lebih efektif, berlandaskan transparansi, akuntabilitas, dan penghormatan HAM. Penelitian ini bertujuan mengkaji peran Polsek Banjarsari dalam mewujudkan rule of law, mengidentifikasi tantangan utama di lapangan, serta merumuskan strategi untuk meningkatkan efektivitas penegakan hukum di tingkat lokal. Melalui pendekatan kuantitatif dipadukan kualitatif analisis data empiris, penelitian ini diharapkan memberikan gambaran menyeluruh tentang penguatan Polsek sebagai bagian penting dalam membangun sistem hukum yang lebih responsif, efektif, dan berkeadilan.

Abstract

The city of Banjarbaru has been designated as the capital of South Kalimantan Province, a status that has the potential to trigger changes in land cover as part of regional development. Therefore, a study of land cover changes supervised the classification approach. The remote sensing data used were Landsat images from 2015 and 2025, with classification classes applied to vegetation, bare land, built-up land, and water bodies. Accuracy testing was carried out using a confusion matrix, the result of which indicated that the accuracy value was within the range permitted (>75%) by the Indonesian National Institute of Aeronautics and Space, so the classification result was considered satisfactory for further analysis. The dynamics of land change in the city of Banjarbaru have been quite significant over the last 10 years. The changes are visible in built-up land, which has changed by around 307.81%, followed by a decrease in bare land area in 2025. These changes indicate that a significant amount of open land has been converted into built-up land. This phenomenon indicates the potential for classification bias. Areas with sparse vegetation or hardened soil, such as post-fire land, former mining sites, or dry rice fields, may be misclassified as built-up areas because their spectral characteristics resemble surfaces like concrete or asphalt. For example, dry rice fields during the dry season or after harvest often show high reflectance and a homogeneous texture, making them appear similar to open land. These conditions were further influenced by the El Niño event in 2015.
