Abstract

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.   Keywords: GNSS, GPS Kinematic, GPS Velocity, Plate movement, Tsunami trigger 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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

Gross Regional Domestic Product (GRDP) is a macroeconomic indicator of the economic condition in a region. The development of GRDP per capita is often used as an indicator of a region's success in economic development. One of the economic sectors that is an indicator of the success of regional development is the mining and excavation sector. East Kalimantan Province is a province with a wealth of natural resources in the form of coal mining. The purpose of this study is to analyze the effect of mining activities in East Kalimantan on the value of the GRDP and the economic conditions in that region. The results showed that mining activities had a significant effect on the GRDP per Capita and the economic conditions of the people in East Kalimantan Province. GRDP according to mining and excavation fields has an effect of 0.9431 on GDP per capita in East Kalimantan Province. The number 0.9431 in statistics means that the X coefficient has a strong effect on the Y coefficient. All decreases and increases in mining and excavation fields have a significant and proportional effect on the economic conditions of the people in East Kalimantan Province.Keywords: Gross Regional Domestic Product (GRDP), mining, economic conditions, East Kalimantan.

Abstract

Indonesia has many environmental problems, especially those related to mining. It becomes essential to provide environmental education to the younger generation. However, the environmental education curriculum has not been explicitly found in the body of formal education in Indonesia. The study area is in Gunungkidul Regency, Indonesia where the limestone mining industry has expanded in almost all areas. The purpose of this study is to assess the environmental impacts of limestone mining activities and align the possible integration of environmental education in the study area. To gather data about the environmental impacts of limestone mining activities, a desktop study, field investigation, and interviews with local communities were conducted. Analysis of the Indonesian curriculum and interviews with elementary school teachers were conducted to align the possible integration of environmental education. The environmental impacts of limestone mining activities in the study area include air pollution, water contamination, drought, soil erosion, and road damage. We provide some suggestions for learning materials including an Introduction to environmentally friendly mining activities (Science subjects, grade 4, thematic 3), an Introduction to air pollution impacts in the mining area on human breathing (Science subjects, grade 5, thematic 2), and Introduction about mining activities impacts on the air, water, and soil (Science subjects, grade 5, thematic 8). It is recommended that teachers not only teach theory but also practice and environmental observation.

Abstract

The purpose of mine dewatering system is to control runoff water that enters mine openings so that the mining process is not disturbed. The rainfall discharge (Q) is 0.0951 m³/second and the runoff discharge (Q) is 0.69 m³/second, making the total mining discharge entering the location 0.781 m³/second. The open channel design has dimensions of Channel wall slope (α) = 60°, Water depth (h) = 0.73 m, Channel depth (d) = 0.83 m, Channel base width (B) = 0.73 m, Surface width (b) = 1.57 m, Wet cross-sectional area of channel (A) = 0.92 m², and Channel wall length (a) = 0.97 m. The sedimentation pond has the following dimensions and compartments: Total length (l) = 104 m; width (b) = 8 m; depth (H) = 4 m; partition width = 4 m; partition depth = 4 m; partition length = 7 m. It consists of 3 compartments: conditioning compartment, separation between solids and mine water, and flow with an area of 277 m² per compartment. The sedimentation pond volume is 3094 m³ with a total area of 830 m². The results of the study obtained information that to control runoff water entering mine openings, a pond capacity as a settling site was needed of more than 3094 m³ with a maximum dredging time of settling pond particles that can be done once every 10 months.

Abstract

The presence of water in mining activities is common, especially in tropical areas that have high rainfall, such as the research location at PT ANTAM Maluku Utara at the Moronopo Site. While the sump maintenance needs to be considered so that the sump can accommodate the incoming discharge. The purpose of this research is to calculate the total discharge entering the mine and to design the dimensions of the sump according to the incoming water discharge. The research method used is the Gumbel method starting from the analysis of rainfall data at the research location starting in 2004-2013 and then continuing with 2019-2020 data, the planned rainfall value is 96.56 mm/day, rainfall intensity is 15.63 mm/day hours with a rain return period of 25 years and a hydrological risk of 18.46 % and the total inflow of mine water is 17,556 m3/hour. After calculating the sump capacity in the Danis 2 area, it still has not accommodated the incoming discharge with the remaining unaccommodated discharge of 2,319.1 m3/hour.
