Landslide is one of movement of soil, rock, soil creep, and rock debris that occurred the move of the slopes. It is caused by steep slopes, high rainfall, deforestation, mining activities, and erosion. The impacts of the landslide are loss of property, damage to facilities such as homes and buildings, casualties, psychological trauma, disrupted economic and environmental damage. Based on the impacts of landslide, mitigation required to take early precautions are to know how the pattern of association between the sequence of events landslides and to know how the associative relationship pattern of earthquakes. Based on the impacts, the results of this research is associative relationship pattern is obtained from data flood that occurs in Indonesia, namely in case of heavy rain will occur labile soil structure to support the value of 0.37, confidence level of 41% and the power of formed ruled is 1.02.

This research is backgrounded by some environmental problems which increasingly worries day plus the problem of management of natural resources that are not friendly and tend to be greedy. The rapid pace of development and population growth in the past decade has led to the conversion of forest and agricultural land into industrial, plantation and residential areas, resulting in degradation of uncontrolled environmental damage and pollution. The main purpose of this research is to know how environmental management conducted by Pondok Pesantren SPMAA Lamongan, East Java. In addition, the purpose of this study to find out how the implementation of environmental management conducted by the boarding school as a mirror of concern for the surrounding environment. This research uses qualitative approach. This means that the data collected is not a number, but the data comes from interviews, personal documents, memo notes, field notes, and other official documents. So that the purpose of this study is to describe the empiric reality behind the phenomenon in depth, detailed, and thorough. This research concludes that every pesantren has its own characteristic in running the concept of ekopesantren that exist, and in this pesantrenen pesantren SPMAA ekopesantren understood as pesantren that can coexist with nature and full of lesson will utilize resources wisely and wisely. Although this boarding school has not fully implemented ekopesantren. This is seen from ecopesantren indicator that has been fulfilled and that has not been fulfilled.

Many technical infrastructure operators manage facilities distributed over large areas. They face the problem of finding out if a flood hit a specific facility located in the open countryside. Physical inspection after every heavy rain is time and personnel consuming, and equipping all facilities with flood detection is expensive. Therefore, methods are being sought to ensure that these facilities are monitored at a minimum cost. One of the possibilities is using remote sensing, especially radar data regularly scanned by satellites. A significant challenge in this area was the launch of Sentinel-1 providing free-of-charge data with adequate spatial resolution and relatively high revisit time. This paper presents a developed automatic processing chain for flood detection in the open landscape from Sentinel-1 data. Flood detection can be started on-demand; however, it mainly focuses on autonomous near real-time monitoring. It is based on a combination of algorithms for multi-temporal change detection and histogram thresholding open-water detection. The solution was validated on five flood events in four European countries by comparing its results with flood delineation derived from reference datasets. Long-term tests were also performed to evaluate the potential for a false positive occurrence. In the statistical classification assessments, the mean value of user accuracy (producer accuracy) for open-water class reached 83% (65%). The developed solution typically provided flooded polygons in the same areas as the reference dataset, but of a smaller size. This fact is mainly attributed to the use of universal sensitivity parameters, independent of the specific location, which ensure almost complete successful suppression of false alarms.


The study was undertaken to design a weir in sivakasi lake of Tamil nadu. The present details of the lake such as combined catchment, intercepted catchment of the lake, full tank level, maximum water level of the tank, bund level, ground level and details of the weir such as size of the weir, materials used for the construction of the weir were analysed. And we have collected the population in that area, rain fall data, flood ratio of that particular lake and total number of houses in that area, number of houses in upstream and number of houses in down stream of the lake. The cause of designing a weir is due to the damage in the existing weir and bunds of the lake so it cannot with stand the pressure of the water in heavy rain fall. To avoid the flood water entering in the residential areas near by the lake we have designed a weir. So that the water can be saved in the lake and there will be no flood occurs in due to the heavy rain fall.

All users of sea transportation in Indonesia in particular and in the world in general, place great importance on safety and security issues. They are vital to avoid accidents which can include the sinking or burning of ships, collisions and running aground. The causes of accidents can be broken down into three groups: human factors; technical factors; and weather factors. These can result in loss of life, psychological trauma to survivors, material losses, and environmental damage. This study proposes the following as key considerations in the reduction of accidents: the provision of safe practice guidelines; identify and introduce protections for all risk categories; continuously improve onboard and personal safety measures. In addition, measures can be taken to mitigate the impact of accidents after they occur, such as responsivity, the collection of evidence to establish why accidents occur and ensure they do not occur again, good leadership and demeanors from ship personnel.

AbstractThe flood disaster that struck the Province of South Sulawesi (South Sulawesi) at the end of January 2019, was the worst natural disaster in the past 20 (twenty) years. Of the 24 (twenty four) districts and cities in South Sulawesi, there are 6 (six) districts and cities experiencing very poor conditions, namely the Regencies of Jeneponto, Maros, Gowa, Takalar, Barru and Makassar. As a result of this disaster, tens of thousands of families lost their homes, property was destroyed, social facilities such as schools and houses of worship were also severely damaged and some were destroyed. Even more pathetic, because more than a hundred people died. This results from an imbalance of ecosystems causing serious problems. Community understanding of the need to maintain ecosystem balance is still very low coupled with the socioeconomic situation which makes the community more pragmatic. The problem is, how do you increase the awareness of the community in maintaining the balance of the ecosystem? And how to foster disaster-conscious attitudes and behavior for the community, especially in disaster-prone areas? Therefore, the writing of this article aims to comprehensively examine people's attitudes related to maintaining ecosystem balance and fostering disaster-conscious behavior in the community, especially in disaster-prone areas as an alternative to disaster risk management. The method used is qualitative with the type of case study studies. The selection of informants is done purposively and the data processed are primary and secondary. From the results of this study it was found, the increasingly severe environmental damage became the main trigger of natural disasters that occurred in South Sulawesi at the end of January 2019. This environmental damage, is dominant because of the very exploitative behavior of the community towards the environment. For example, what happened in Gowa district, the big floods that occurred because around the Jeneberang River and Bili-Bili Dam areas - sand mining activities have been going on for decades. Likewise, the Mount Bawakaraeng area, which used to function as a buffer against flooding, has long been deforested as a result of causing landslides whenever there is heavy rain. This condition also occurs in the districts of Jeneponto, Maros and others - these areas are vulnerable to heavy rainfall. To overcome this serious problem, one alternative is to form community groups that are aware of disasters. This strategy of forming disaster awareness groups, by combining approaches from above (government) and from below (the community)   Musibah banjir yang melanda Provinsi Sulawesi Selatan (Sulsel) di akhir Januari 2019, merupakan bencana alam yang terparah selama kurun waktu 20 (dua puluh) tahun terakhir ini. Dari 24 (dua puluh empat) kabupaten dan kota di Sulsel, ada 6 (enam) kabupaten dan kota mengalami kondisi sangat memprihatinkan yaitu Kabupaten Jeneponto, Maros, Gowa, Takalar, Barru dan Makassar. Akibat dari bencana ini, puluhan ribu keluarga kehilangan tempat tinggal, harta benda musnah, fasilitas sosial seperti sekolah dan rumah ibadah juga rusak berat dan ada yang hancur. Lebih mengenaskan, karena menimbulkan korban jiwa meninggal dunia lebih dari seratus orang. Hal ini akibat dari ketidakseimbangan ekosistem menyebabkan masalah yang serius. Pemahaman masyarakat tentang perlunya menjaga keseimbangan ekosistem, masih sangat rendah ditambah lagi dengan situasi sosial ekonomi yang membuat masyarakat makin pragmatis. Masalahnya, bagaimana cara meningkatkan kepedulian warga masyarakat dalam menjaga keseimbangan ekosistem? Dan bagaimana menumbuhkan sikap dan perilaku sadar bencana bagi masyarakat khususnya di kawasan yang rawan bencana? Karena itu, penulisan artikel ini bertujuan untuk mengkaji secara komprehensif sikap masyarakat terkait dengan kepedulian menjaga keseimbangan ekosistem dan menumbuhkan perilaku sadar bencana di masyarakat khususnya di daerah-daerah yang rawan bencana sebagai alternatif manajemen risiko bencana. Metode yang digunakan adalah kualitatif dengan jenis kajian studi kasus. Pemilihan informan dilakukan secara purposif dan data yang diolah adalah primer dan sekunder. Dari hasil penelitian ini ditemukan , makin parahnya kerusakan lingkungan menjadi pemicu utama dari bencana alam yang terjadi di Sulsel akhir Januari 2019.. Kerusakan lingkungan ini, dominan karena perilaku masyarakat yang sangat eksploitatif terhadap lingkungan. Misalnya saja yang terjadi di kabupaten Gowa, banjir besar yang terjadi karena di sekitar kawasan Sungai Jeneberang dan Dam Bili-Bili – kegiatan penambangan pasir sudah berlangsung puluhan tahun lamanya. Begitu juga kawasan Gunung Bawakaraeng yang tadinya berfungsi sebagai penyangga banjir, karena sudah lama digunduli akibatnya menimbulkan longsor setiap ada hujan deras. Kondisi ini juga terjadi di Kabupaten Jeneponto, Maros dan lainnya – daerah-daerah ini rentan terhadap curah hujan yang besar. Untuk mengatasi masalah serius ini, maka salah satu alternatifnya dengan membentuk kelompok-kelompok masyarakat yang sadar bencana. Strategi pembentukan kelompok sadar bencana ini, dengan memadukan pendekatan dari atas (pemerintah) dan dari bawah (masyarakat)

Physical properties of soil have been measured on two experimental plots which showed high compaction and poor germination of wheat under very wet conditions. The plot treatments were a two-course and a four-course rotation, and formed part of a permanent rotation trial at the Waite Institute. Similar physical properties were measured for thick crusts formed on these cultivated soils. Under the wet conditions pore space available for air was low in both plots, and within the crust itself was almost zero. Significant differences were found in bulk density and water-stable aggregation between treatments. Waterstable aggregation was very low under both treatments compared with that in virgin soil. All physical measurements point to an oxygen deficiency for a period of 2-3 weeks, and this could account for the poor germination and poor early growth, particularly in the two-course rotation plots. The bad structure conditions leading to this are probably due to pulverizing by implements and dispersion over the years by heavy rain, rather than to decrease in organic matter.

Open access land mining activities on the Lubuk Selasih – Surian national road have in floods and landslides that have, in losses to the community and the imposition of costs for maintenance and rehabilitation of federal roads along the mining area. This study aims to determine the existing condition of mining and analyze the vulnerability of erosions in mining areas. The data used is secondary data, using descriptive quantitative methods with photogrammetric analysis of the maps obtained. The results showed that this mining area has the characteristics of rocks that are easily crushed and tend to be unstable, as well as steep and very steep slopes. This area is also located on the active Semangko fault and volcanic mountains. The environmental carrying capacity of disaster prevention and protection ecosystem services is mainly in the shallow categories. Based on these findings, the mine site is at a very high level of vulnerability to erosions. Thus, it is necessary to mitigate mining management administratively and operationally to minimize environmental damage
