Abstract

Flooding hit the island of Ambon in 2012 and 2013. Many analyzes has been developed to estimate the cause of the flooding. The study aims topredict optimal land management for reducing run-off. The method is simulation of CN value based on spatial analysis on watershed characteristics.The rainfall can’t be managed by watershed. The level of run-off can be determined by CN value that depends on the type of land cover. The resultshows that the land cover has changed about 90 ha, with the higher rainfall intensity is 2.118 in 2013. The result of simulation indicated that tochange of shrub and bare land, mix dryland forest, and secondary dryland forest with agroforestry. Agroforestry can decrease run-off amount 0,86%.The change of land cover and high rainfall are the main factors that caused the flooding in 2012 and 2013. It is necessary to add a rainfallobservation station so that the observation of surface flow can be done well.Keywords: curve number, land cover change, watershed

Abstract

Pasca Revolusi Industri keempat telah terjadi perubahan yang jauh massif pada aspek sosio-kutural. Disatu sisi, terdapat perilaku digital yang kurang produktif bahkan potensi berinternet secara desktruktif. Di sisi lain terdapat pula fenomena pengembangan perangkat maya untuk menyokong pembangunan demokrasi, pemajuan peradaban sosial, dan penguatan budaya warga negara partisipatif di era digital menjadi suatu yang urgen. Proses membangun dan mengembangkan akses digital sebagai wahana bagi warga negara mengaktualisasikan partisipasi publik pada sektor sosial kemanusiaan menjadi gejala yang menarik untuk dikaji secara ilmiah. Penelitian ini adalah kajian teoretis terhadap fenomena aktivisme daring melalui pemanfaatan internet dan media digital di Indonesia dalam rangka pembinaan partisipasi warga negara di era digital. Melalui penelitian ini, akan dikaji aktivisme daring melalui pemanfaatan internet dan media digital di Indonesia secara teoretis berdasarkan hasil kepustakaan. Studi-studi tentang internet dalam kaitannya dengan aktivisme gerakan sosial sebagaimana disebutkan telah menghasilkan dua perspektif. Kesatu bahwa internet dapat memfasilitasi aktivisme pada ranah luring. Kedua, internet meningkatkan praktik gerakan yang ada dengan menambahkan kampanye secara daring melalui berbagai metode. Kajian ini mejadi penting untuk diangkat sebagai topik didasarkan pada beberapa alasan. Kesatu secara teoretis, terdapat kebermanfaatan bagi lapangan ilmu pendidikan kewarganegaran yakni kajian pada aspek citizenship education pada domain sosio-kultural. Kedua secara praksis, bahwa apa yang ditemukan dapat mengungkap best practice berwarganegara di era digital. Bisa kita dapatkan faktor pendorong yang kemudian bisa kita prediksikan faktor yang membuat budaya positif berupa partisipasi sosial berbasis digital ini bertahan.

Abstract

The recurrent incidence of floods and flash floods across various regions of Indonesia has incited ongoing public and scholarly discourse that attributes hydrometeorological factors and deforestation as principal contributors to hydrometeorological disasters. This perspective adds a view angle to typical cause-and-effect discussions about floods and flash floods, proposing a two-pronged approach to address their challenges. Though not entirely new, it emphasizes the importance of prioritizing disaster prevention over simply managing the aftermath.

Abstract

Landslides are one of the most frequent and destructive natural disasters in Indonesia, yet national susceptibility assessments still rely heavily on heuristic frameworks based on expert judgments. This study evaluated the performance and interpretability of two Machine Learning (ML) models, Logistic Regression (LR) and Decision Tree (DT), compared with the heuristic baseline for landslide susceptibility mapping in the Ciujung sub-watershed, West Java-Banten. The models were developed using the NASA Global Landslide Catalog and 13 conditioning factors at 30 m spatial resolution. The LR model passed the multicollinearity test and identified annual rainfall, soil texture, and land use as dominant factors, while DT identified the same factors as the main controller, but emphasized the role of local threshold and interactions between factors. Slope does not appear as a dominant factor due to the mudslide character that not only occurs on steep slopes, but also spreads to flatter areas as deposition zones, thereby reducing the discriminating power of slope in pixel-based modeling. The models of LR and DT performed quite well (AUC>0.9) and generated spatially limited susceptibility zones. In contrast to the heuristic baseline, which sometimes overestimates the hazard areas. The findings indicated that LR and DT frameworks are able to improve the methodological transparency, spatial accuracy, and policy relevance, offering a viable approach for evidence-based catastrophe governance.

Abstract. Fata YA, Hendrayanto, Erizal, Tarigan SD, Wibowo C. 2022. Vetiver root cohesion at different growth sites in Bogor, Indonesia. Biodiversitas 23: 1683-1692.The plant root system, including the root system of vetiver grass, plays a critical role in enhancing soil cohesion, shear strength, and vegetated slope stability. Numerous studies on mechanical reinforcement of vetiver grass-roots have been conducted, with the majority of studies focusing on ground-planted vetiver with good maintainedor naturally grown vetiver, while mechanical reinforcement of vetiver grass roots planted in landslide areas at various growth sites with less maintenance is still uncommon.The purpose of this study was to examine the vetiver grass-roots cohesion that grew in the different growth sites that had been affected by landslides. Vetiver grass root samples were collected in January 2021, at the age of 8 months. Vetiver grass roots were collected from vetiver plants growing in the affected landslide areas of (a) bareland, (b) shrubland, and (c) bushland. The root tensile strength of root samples was determined using a Universal Testing Machine (UTM) with a capacity of 3 tons, and the measurement accuracy of the load cell was 1/10000. The test was conducted in accordance with ASTM D638-14 guidelines. Three repetitions were performed on roots representing the root length class of 10 cm. The results indicated that the growth sites influenced the morphological and architectural properties of the vetiver grass-roots. The vetiver grass that grew in bushland exhibited a higher root density than bareland or shrubland. The roots were denser and had a greater range of lengths. Short roots less than 10 cm in length were the most prevalent, and the majority of them were found near the soil surface. The greater the soil depth, the less the quantity of roots.The tensile strength (TR) tends to get smaller with longer roots, and vetiver grass rootsgrew in bareland have the highestTR(15-59 MPa) relative to their growth in bushland (9-37 MPa) and shrubland (16-29 MPa). The ratio of root fiber area to root growth area (RAR) also tends to get smaller with deeper roots. Likewise, is the tensile strength increasing caused by roots (tR) and root cohesion (CR) which are a function of RAR. The CR??of vetiver roots growing in bushland (0.015-0.275 kPa) were relatively higher than those growing in bareland (0.02-0.168 kPa) and shrubland (0.002-0.028 kPa) in the same root length class, at the same depth.

Abstract

The presence of groundwater in the groundwater basin increases the potential of rainwater seeping into the soil and reaching the groundwater system. As a result, the soil takes longer to get saturation and maintain its stability. The groundwater basin stability is also influenced by the layer's lithological, soil, and morphological properties above the groundwater system and human activities on the land. The purpose of this study was to characterize the groundwater basins, non-groundwater basins, and landslides that happened in those locations in the tropical region of Bogor, Indonesia. The characteristics of landslide events, including lithological, groundwater table, soil, slope, and land use in each groundwater basin zone, were evaluated using quantitative descriptive analysis. The result showed 686 landslides from 2015 to 2019 that mainly occurred in the discharge zone, characterized by slope classes of >45%, soil types of Technosol (Inceptisols), Quaternary lithology periods, and settlement land use. The landslide type in the groundwater basin is dominated by surface landslides, while the landslides in the non-groundwater basin are mostly shallow landslide types.

Abstract

Bogor, Cianjur, and Sukabumi areas of West Java Province, Indonesia, are vulnerable landslide areas. This study analyzes the landslide characteristic and the factors affecting landslides. The analysis was carried out on 148 landslides from 415 of 2018-2020 landslides, which were selected purposively by considering the heterogeneity of soil, geology, slope classes, land use type, and accessibility of landslide locations. Landslide characteristics and factors affecting landslides were analyzed using frequency analysis and binary logistic regression. The results showed that the most dominant characteristics of surface and shallow landslides were the landslides characterized by slopes >45%, Quaternary geological period, Andisol soil type, agriculture land use type, the occurrence of rain, and absence of earthquake. The dominant factors affecting surface and shallow landslides are human activities in land use, soil properties, steep-very steep slopes, Inceptisol and Entisol soil orders, young rocks (Quaternary geological period), rainfall events, and high earthquake magnitude.

Abstract

Root system mechanical reinforcement through root-soil cohesion on slope stability is important. However, the root cohesion of Tectona grandis, Maesopsis eminii, and shrubs (Chromolaena odorata) on slope stability is rarely studied and modelled. This study aimed to model the mechanical effect of vegetation through root cohesion, namely teak (Tectona grandis), Maesopsis eminii, and shrubs (Chromolaena odorata). The study was conducted in a simultaneous landslide on January 1, 2020, that dominantly occurred on vegetated slopes of Sukajaya District, Bogor Regency, West Java. The Wu model's root cohesion (CR) was modelled on slope stability using a modified Bishop model. The modelling used the data from field and laboratory-measured. The study found that the presence of a root system increases slope stability's factor of safety (FOS). The root system of young Maesopsiss eminii produces the largest effect of FOS compared to the root system of shrubs, teak, and old Maesopsis eminii. The slope stability of vegetated slopes is a function of the CR and the effective root zone depth. The highest total CR of vegetation was teak with 0.398 kPa, followed by shrubs, young Maesopsis eminii, and old Maesopsis eminii with 0.202 kPa, 0.191 kPa, and 0.087 kPa, respectively. The effective root zone of teak, young Maesopsis eminii, and shrub were 500, 230, 140, and 66 cm, respectively.
