The ancient Zhenggang landslide (47.5 million m3) represents a potential threat to the construction and safe operation of the proposed Gushui Hydropower Project and to the people living downstream. The landslide was caused by continuous rainfall from October 20 to November 5, 2008, indicating that groundwater aggravated sliding and deformation, and it can be divided into two distinct zones: zone I and zone II. Investigations of the Zhenggang landslide deposits have been conducted for 10 years, but the evolution of the landslide deformation is yet to be revealed. Geological surveys and stability analysis have revealed that the Zhenggang landslide is currently relatively stable and is not sliding. The deformational data for the deep soil layers show that subslide zone I is a translational slide, while subslide zone II is an uplift slide, and zone II is slightly more stable than zone I. Obvious interior deformational failure occurred and was observed in the exploratory adits. The numerical results show that rainfall infiltration is the main factor to induce the revival of ancient landslide, and it is necessary to strengthen the landslide risk assessment and reliability of Zhenggang landslide under the condition of rainfall infiltration. Finally, in order to reduce landslide risks, the local residents living near the landslide mass should be relocated, and measures should be taken to increase slope stability.

Abstract. Landslides of contaminated soil into surface water represent an overlooked exposure pathway that has not been addressed properly in existing risk analysis for landslide hazard, contaminated land, or river basin management. A landslide of contaminated soil into surface water implies an instantaneous exposure of the water to the soil, dramatically changing the prerequisites for the mobilisation and transport of pollutants. In this study, an analytical approach is taken to simulate the transport of suspended matter released in connection with landslides into rivers. Different analytical solutions to the advection-dispersion equation (ADE) were tested against the measured data from the shallow rotational, retrogressive landslide in clayey sediments that took place in 1993 on the Göta River, SW Sweden. The landslide encompassed three distinct events, namely an initial submerged slide, followed by a main slide, and a retrogressive slide. These slides generated three distinct and non-Gaussian peaks in the online turbidity recordings at the freshwater intake downstream the slide area. To our knowledge, this registration of the impact on a river of the sediment release from a landslide is one of few of its kind in the world and unique for Sweden. Considering the low frequency of such events, the data from this landslide are highly useful for evaluating how appropriate the ADE is to describe the effects of landslides into surface water. The results yielded realistic predictions of the measured variation in suspended particle matter (SPM) concentration, after proper calibration. For the three individual slides it was estimated that a total of about 0.6% of the total landslide mass went into suspension and was transported downstream. This release corresponds to about 1 to 2% of the annual suspended sediment transport for that river stretch. The studied landslide partly involved an industrial area, and by applying the analytical solution to estimate the transport of metals in the sediments, it was found that landslides may release a significant amount of pollutants if large contaminated areas are involved. However, further studies are needed to develop more detailed descriptions of the transport processes. There is also a need to increase the knowledge on possible environmental consequences in the near and far field, in a short- and long-time perspective. In summary, the release of pollutants should not be neglected in landslide risk assessments.

The people of Yogyakarta are known for their tolerance, where people of different religions can coexist peacefully especially with Javanese traditions. But in Mangir, a village in Bantul, Yogyakarta, in November 12, 2019, there was a case of local residents rejecting the procession of ancestral prayer rituals by the Paguyuban Padma Buana (PPB) who claims to be followers of Javanese Hinduism. This study aimed at disclosing the elements and roots of conflict from the Mangir community's rejection towards Paguyuban Padma Buana. As a case study, it used conflict analysis approach through timeline and factor analysis techniques. The results showed that the open conflict between the two groups has occurred since 2012 with the main issue of syncretic ritual practices of Hinduism, Buddhism, and Kejawen (Javanism) that involve people from various religions. In addition, the Maha Lingga Padma Buana Temple as a place of whorship and rituals has also the license problems. Reconciliation was carried out between residents with the Padma Buana followers in 2015. Unfortunately it was violated by the Paguyuban Padma Buana and became a trigger of conflict back in 2019. The cause of this conflict is multiple factors, all of which are interrelated. However, the root cause of the problem among Mangir people is mostly related to traditional revivalism and the distribution of cultural tourism management authorities. This conflict makes them polarized and vulnerable to interests that can create the village atmosphere worse

Penelitian ini bertujuan untuk mendeskripsikan latar belakang Jepang di Bima dan reaksi Sultan dan masyarakat Bima terhadap kedatangan Jepang serta dampaknya terhadap masyarakat. Penelitian ini menggunakan pendekatan ilmu sejarah, sehingga tahap penelitian yang dilakukan adalah (1) Heuristik atau pengumpulan data, (2) Kritik (3) Interprtasi dan (4) Historiografi. Hasil penelitian menunjukkan bahwa bahwa Berdasarkan  pada pembagian wilayah kontrol pendudukan Jepang di Bima bahwa kawasan Indonesia bagian timur berada di bawah kontrol Armada (Angkatan) Laut yang berpusat di Makassar. Setelah menduduki Sulawesi Selatan pada tanggal 9 Februari 1942, Jepang terus melakukan gerak invasinya ke Nusa Tenggara, antara lain Kupang di Nusa Tenggara Timur (NTT) serta Bima di Kepulauan Sumbawa. Armada Laut Jepang dibawah pimpinan Kolonel Saito mendarat di Pelabuhan Bima pada tanggal 17 Juli 1942. Kedatangannya di sambut baik oleh penduduk setempat, sekalipun mereka (masyarakat Bima) di selimuti rasa khawatir atas rencana Asisten Residen Belanda, H.E. Haak untuk kembali berkuasa di Bima, karena itu dengan mudah Jepang menduduki Bima. Dampak keberadaan Jepang di Bima dibidang sosial diantaranya terjadi keresahan sosial dan porak-porandanya tata kehidupan sosial masyarakat. Agama dan adat yang selama ini dijunjung tinggi oleh masyarakat “terpaksa” harus dilanggar. Sementara dampak dibidang Ekonomi, berupa keterpurukkan Ekomomi, sebab masyarakat tidak lagi mencurahkan perhatian sepenuhnya untuk mengolah lahan pertaniannya. Penderitaan masyarakat berakhir setelah Jepang kalah dan menyerah tanpa syarat kepada sekutu pada bulan Agustus 1945. Sejak itu, pemerintahan pendudukan Jepang berakhir di Bima khususnya dan Indonesia pada umumnya. Kata Kunci: Pendudukan, Japang di BimaAbstractThis study aims to describe the background of Japan in Bima and the reaction of the Sultan and the people of Bima to the arrival of Japan and its impact on society. This study uses a historical science approach, so the stages of research carried out are (1) Heuristics or data collection, (2) Criticism (3) Interpretation and (4) Historiography. The results showed that based on the division of the Japanese occupation control area in Bima that the eastern part of Indonesia was under the control of the Naval Fleet (Force) based in Makassar. After occupying South Sulawesi on February 9, 1942, Japan continued to make its invasion moves to Nusa Tenggara, including Kupang in East Nusa Tenggara (NTT) and Bima in the Sumbawa Islands. The Japanese Sea Fleet under the leadership of Colonel Saito landed at the Port of Bima on July 17, 1942. His arrival was welcomed by local residents, even though they (the Bima people) were shrouded in worry over the plan of the Assistant Resident of the Netherlands, H.E. Haak to return to power in Bima, because it easily Japan occupied Bima. The impact of the existence of Japan in Bima in the social field included social unrest and ruins of the social order of the community. Religion and customs that have been upheld by the community are "forced" to be violated. While the impact on the economy, in the form of deterioration in the economy, is because the community no longer pays full attention to cultivate its agricultural land. The suffering of the people ended after Japan's defeat and surrender unconditionally to the allies in August 1945. Since then, the Japanese occupation government ended in Bima in particular and Indonesia in general. Keywords: Occupation, Japanese in Bima

Identification and classification of landslides is a preliminary and crucial work for landslide risk assessment and hazard mitigation. The exploitation of surface deformation velocity derived from satellite synthetic aperture radar interferometry (InSAR) is a consolidated and suitable procedure for the recognition of active landslides over wide areas. However, the calculated displacement velocity from InSAR is one-dimensional motion along the satellite line of sight (LOS), representing a major hurdle for landslide type and failure mechanism classification. In this paper, different velocity datasets derived from both ascending and descending Sentinel-1 data are employed to analyze the surface ground movement of the Huangshui region (Northwestern China). With global warming, precipitation in the Huangshui region, geologically belonging to the loess basin in the eastern edge of Qing-Tibet Plateau, has been increasing, often triggering a large number of landslides, posing a potential threat to local citizens and natural and anthropic environments. After processing both SAR data geometries, the surface motion was decomposed to obtain the two-dimensional displacements (vertical and horizontal E–W). Thus, a classification criterion of the loess landslide types and failure mode is proposed, according to the analysis of deformation direction, velocities, texture, and topographic characteristics. With the support of high-resolution images acquired by remote sensing and unmanned aerial vehicle (UAV), 14 translational slides, seven rotational slides, and 10 loess flows were recognized in the study area. The derived results may provide solid support for stakeholders to comprehend the hazard of unstable slopes and to undertake specific precautions for moderate and slow slope movements.

In My Back Yard is a documentary film that explores the changing landscape of the Mount Dennis neighbourhood in Toronto. This change is represented by the 54-acre Kodak site that is being transformed into the second largest transportation hub in the Greater Toronto Area. The film employs a series of visual strategies and retells recent observations related to the impact of this massive infrastructure project on the people, the land and the urban wildlife. Local residents, politicians and community leader were consulted. Their interviews are combined with dioramas, archival photographs and time-lapse photography to express the multi-facetted list of community concerns. This support paper attempts to define and analyse these struggles within the context of Leo Marx’s 1964 work The Machine in the Garden: Technology and the Pastoral Ideal in America. This paper proposes that Marx’s concept of the “middle landscape” helps to define the current struggle in Mount Dennis.

Sidotopo Village, Kedungsari Village, North Magelang, Magelang City is a densely populated area and a wide variety of people live in the area. The characteristics of the people who live in the area are diverse in their occupations and education, some residents do not receive formal education and some residents also work odd jobs, ranging from garbage collectors, food sellers and others. Awareness of a clean, healthy and characterized life seems to be lacking in local residents, as evidenced by the fact that there are still people who throw garbage in the river, do not recognize the importance of exercise and food intake with good nutrition, and lack of understanding of national character in terms of defending the country. Mentoring/socialization about clean, healthy and character living is a solution in forming a healthy and characterized society. The assistance provided to the community is an understanding of clean living, an understanding of the importance of maintaining health by exercising, and the importance of having a strong national character. So there is great hope to add insight to the community to be able to live healthy and have character in Sidotopo Village. Keywords: Clean Living, Healthy Exercise, Love for the Motherland.Kampung Sidotopo Kelurahan Kedungsari Magelang Utara Kota Magelang merupakan daerah yang padat penduduk dan beraneka ragam masyarakat yang tinggal di daerah tersebut. Karakteristik masyarakat yang tinggal di daerah tersebut beraneka ragam pekerjaan dan pendidikanya, beberapa penduduk ada yang tidak mengenyam pendidikan secara formal dan beberapa penduduk juga ada yang bekerja serabutan, mulai dari pengepul rongsok, penjual makanan dan lain-lain. Kesadaran akan hidup bersih, sehat dan berkarakter nampaknya kurang dirasakan oleh penduduk sekitar, terbukti dengan masih adanya masyarakat yang membuang sampah di kali, tidak mengenalnya pentingnya olahraga dan asupan makanan dengan gizi yang baik, serta kurangnya pemahaman tentang karakter kebangsaan dalam hal bela negara. Pendampingan/sosialisasi tentang hidup bersih, sehat dan berkarakter merupakan solusi dalam membentuk masyarakat sehat dan berkarakter. Pendampingan yangh diberikan kepada masyarakat yaitu pemahaman akan hidup bersih, pemahaman pentingnya menjaga kesehatan dengan berolahraga, serta pentingnya memiliki karakter kebangsaan yang kuat. Sehingga besar harapan menambah wawasan masyarakat untuk dapat hidup sehat dan berkarakter di kampung sidotopo. Kata kunci: Hidup Bersih, Sehat Berolahraga, Cinta Tanah Air.

In Sidomulyo Village there is a weaving craft industry that has the potential to be international. This weaving industry is AJZ's weaving industry, owned by Mrs. Asih Tri Tanti, a full-time female worker. According to the results of an interview with Ms. Asih Tri Tanti on April 13, 2017, it is known that her weaving skills are currently acquired while working as a migrant worker in Brunei Darussalam. Then in 2013, this craftsman returned to Sidomulyo Village to develop the potential of weaving craft in his village. However, there were many obstacles. Finally, from 2013 to 2017, Bu Asih worked with businessmen from the Sultanate of Brunei Darussalam and had been contracted for 10 years by this country. Each sheet, this woven fabric is sold at Rp. 5,000,000. The potential of Asih bu is very likely to be developed. The development of these handicrafts can open employment opportunities from local residents and certainly improve the welfare of the community, especially vulnerable women and women with disability. This service aims to (1) increase the availability of human resources from diffable groups and vulnerable women, (2) shape the mindset of the people who have the character of independence, (3) establish coordination between the government and the community regarding the development of weaving potential, and (4) provide a place for people with disabilities who are members of PPDI to develop their skills. The method of implementation is carried out through seminars and weaving training for vulnerable women and women with disabilities. The results show that UB's community service activities in this weaving training are able to (1) improve Human Resources (HR) (disabled and vulnerable women) in Sidomulyo Village, Blitar Regency, (2) improve the mindset of the people who have the character of independence, and (3) able to change the mindset of the local community to not be ashamed to work in weaving in their own neighbors.
