Geographic Position System (GPS) is an electronic instrument that is used to determine the position of coordinates, with the help of the triangulation of satellite signals it can be accurately determined the coordinates of the position. An embedded GPS station is built to track changes in station positions over a period of time. Changes in position over a period of time are calculated using the GPS kinematic method and summed up simply using the GPS velocity method. International GNSS Service (IGS) is a global GPS data provider service with time-per-second densities and millimeter accuracy. During the Aceh tsunami tragedy 26 December 2004 00.58'.53 "UTC there were 3 GPS stations, each located on a different tectonic plate, the JOGJ station located in Yogyakarta representing the Micro-Sunda plate, the ISSC station located in India representing the Indian plate, and the DGAR station located in the Maldives represents the Eurasian plate as a stable site. The results of data analysis showed that there were 4 phases of tectonic movements during the Aceh tsunami tragedy, anomalous movement phases, pressuring phases, release phases, and stabilization phases. The tectonism study using the GPS station data approach can be used as a parameter to detect plate movement data, especially a great hope for the development of earthquake detection studies.Â Â Keywords: GNSS, GPS Kinematic, GPS Velocity, Plate movement, Tsunami triggerÂ Geographic Position System (GPS) adalah suatu intrumen elektronik yang digunakan untuk mengetahui posisi kordinat, dengan bantuan triangulasi sinyal satelit maka dapat ditentukan posisi kordinat secara akurat.

The frequency of landslides and the fact that a large number of people live in the landslides-prone areas lead to a high death toll in Java Island, Indonesia – over 1,112 people in the period between 1999 and 2005. Indonesian National Disaster Management Agency (Badan Nasional Penanggulangan Bencana [BNPB]) reported 2,766 landslides that occurred in Java from 2014 to 2019, with 662 deaths. From its state, it looks as if Indonesia 's disaster mitigation is still weak. It is very essential to a deep understanding of landslides disaster mitigation weakness in Indonesia with the approach of governments, researchers, and local communities action. This research is a review of landslides disaster mitigation in Java Island with the approach of governments, researchers, and local communities action. Furthermore, the purpose of this study is to highlight the driving forces of landslides disaster mitigation in Java Island, Indonesia. From the assessment of each stakeholder (government, researchers, and local communities), the driving forces of landslides disaster mitigation in Java Island are the central government has commanding disaster management activities to local governments. However, the implementation of landslides disaster mitigation at the regional level has some obstacles such as the lack of residential development planning.Many landslide research results have only become scientific papers but the landslides-prone areas have not been fully paid attention by the local government such as the absence of landslide danger warning signs.In addition, the level of preparedness and awareness among local communities is not constant at any given time. Usually, community preparedness levels can be high following a disaster. It is likely, however, to diminish over time.

This position paper narrates how the author's position based on the hot issue of nurturing the COVID-19 pandemic. The pros and cons of the "New Normal" concept [kenormalan baru] are argumentatively illustrated through a literature search. The primer information from WHO, policymaker, and researchers contributed to the discussion. Health protocols become the rules mentioned in implementing a new normal, namely by reducing physical contact with others. Nevertheless, the new normal policy is no less low and dangerous, is the insufficient appreciation of science, especially revelation. Thus, the concept of the new normal has not valued except just taking material and economic benefits.

Pentingnya ketersediaan RTH bukan hanya secara kualitatif namun juga kualitas bagi sebuah Kota diharapkan mampu untuk menunjang tingkat kenyamanan Kota. Kondisi lingkungan yang buruk dapat meningkatkan stres masyarakat karena terbatasnya ketersediaan ruang terbuka untuk berinteraksi sosial. Kenyamanan Kota Yogyakarta memiliki nilai terendah pada ketersediaan fasilitas ruang terbuka hijau. Terdapat beberapa RTHP di Kota Yogyakarta yang kurang ramah terhadap lansia, anak dan disabiltas karena kurangnya fasilitas dan kontur tanah lokasi RTHP yang dekat dengan sungai. Selain itu, terdapat 14 RTHP atau sebesar 29,79% yang memiliki kualitas kenyamanan tertinggi/sangat nyaman, 26 RTHP atau sebesar 55,32% yang memiliki kualitas kenyamanan sedang/nyaman dan 7 RTHP atau sebesar 14,89% yang memiliki kualitas kurang nyaman di Kota Yogyakarta. Berangkat dari pemikiran-pemikiran tersebut tujuan dari penelitian ini adalah mengidentifikasi karakteristik RTHP dalam menunjang kenyamanan Kota Yogyakarta. Hasil perbedaan karakteristik RTHP akan diklasifikasikan berdasarkan tujuh variabel kenyamanan Kota, yaitu variabel sirkulasi, kebersihan, keamanan, keindahan, bentuk, kebisingan dan penerangan. Metode yang dipergunakan adalah analisis deskriptif kualitatif yang digambarkan dengan peta kategori RTHP masing-masing variabel. Kategori yang memiliki nilai kesamaan karakteristik dominan adalah kategori yang hanya terdiri dari dua-tiga kode kategori, seperti pada variabel keamanan, penerangan dan sirkulasi. Hal ini menunjukkan bahwa pada ketiga variabel tersebut pemerintah memiliki konsep yang matang dan pemahaman mengenai kenyamanan RTHP. Kategori yang memiliki variasi karakteristik yang cukup luas (banyak memiliki perbedaan karakteristik) yaitu pada variabel keindahan dengan 12 kode kategori. Selanjutnya, kategori prioritas untuk meningkatkan kenyamanan pada variabel sirkulasi adalah kategori A, variabel kebersihan adalah kategori G, variabel keamanan adalah kategori A, variabel keindahan adalah kategori D, variabel bentuk adalah kategori E, kebisingan adalah kategori D dan penerangan adalah kategori A. Untuk perencanaan dan pembangunan RTHP selanjutnya, diharapkan pemerintah memiliki standar dalam mengidentifikasi variabel kenyamanan, sehiggga baik pengunjung maupun masyarakat sekitar dapat lebih nyaman beraktivitas di RTHP yang juga dapat menunjang kenyamanan Kota Yogyakarta.

Taipingshan landslide occurred by Typhoon Saola in 2012. Rainfall recorded in that event occurred was over 1800 mm during three days. Additionally, geological factors such as weathered and erosion materials are also factors that give risk occur landslide. Geoelectrical resistivity is a geophysical method that uses an electrical current into the rock to get resistivity value. The function of geoelectrical resistivity is to determine materials in subsurface based on the resistivity value, which is done by measuring materials on the ground surface. The kinds of landslide material in this area is only one type of rock, it is slate. Differences of resistivity values (some colors in 2D resistivity image), due to several factors, such as weathered and fresh rock, fracture zones in the rock, and rock contacts with water. According to drilling data, 2D resistivity image, and geological map in Taipingshan, reconstruction of the subsurface profile was made to know the depth of potential mass wasting. The kinds of materials derived are colluvium at a depth of 0-10 m, weathered rock (slate) at a depth of 10-29 m, and bedrock (slate) at a depth of 29-100 m. The position of sliding surface was located between the weathered rock (slate) and bedrock (slate) at a depth of around 29 m. The sliding surface is obtained from two materials adjacent that has different contrast of resistivity value. So it is easily moving and eroded in steep slope and when heavy rainfall occurs. So that the thickness of potential mass wasting was around 29 m.
