Abstract

Pada artikel ini akan ditunjukan analisa dari perluasan gauge invariant exact dan metric independent untuk menkontruksi lower-rank field-strength tensor. Hasil ini akan digunakan untuk mengkontruski ulang Chern-Simons-Antoniadis-Savvidy formasi (2n+1) pada dimensi genap dengan menggunakan pendekatan diferensial geometri. Selanjutnya akan dianalisa bentuk topological gravitasi 2-dimensi yang merupakan perluasan dari teorema Chern-Weil yang telah dikembangkan oleh Izurieta-Munoz-Salgado. Hasil dari penelitian ini memperlihatkan bahwa aksi Lagrangian yang sama seperti pada topological gravitasi Chern-Simons forms pada dimensi (2n+1) invariant terhadap Poincare group SO(D−1,1)  SO(D−1,2). This article determine and analyess of the extended gauge invariant exact and metric independent to construct the lower-rank field-strength tensor.

Abstract

UAV (Unmaned Aerial Vehicle) atau yang biasa disebut drone saat ini telah banyak digunakan untuk pemetaan wilayah di Indonesia. Salah satu metode penentuan posisi satelit GNSS (Global Navigation Satelitte System) yaitu dengan metode statik. Penelitian ini mengkaji perbadingan ketelitian foto udara UAV dan foto udara UAV yang telah diikatkan dengan GNSS. Tahapan awal dalam penelitian ini adalah dilakukan pengambilan foto udara UAV wilayah Gampong Lambarih, kemudian dilakukan pengambilan data GNSS di lapangan sebanyak 4 titik di kawasan Gampong Lambarih, Aceh Besar dengan menggunakan titik kontrol atau titik ikat stasiun CBDA dengan doy 040 di Jantho. Tiap titik pengamatan dilakukan selama 30 menit dengan interval waktu pengukuran 1 detik. Pengolahan data UAV menggunakan aplikasi Agisoft dan pengolahan data GNSS menggunakan aplikasi HiTarget Geomatic Office (HGO) dan Website BIG. Hasil penelitian menunjukkan foto udara UAV yang diikat dengan GNSS memiliki ketelitian yang lebih tinggi yaitu mecapai ketelitian orde mm. UAV (Unmaned Aerial Vehicle) or what is commonly called a drone is currently widely used for regional mapping in Indonesia. One method of determining the position of the GNSS (Global Navigation Satelitte System) satellite is the static method. This study examines the comparison of the accuracy of UAV aerial photographs and UAV aerial photographs that have been tied to GNSS. The initial stage in this research was to take aerial photographs of the UAV of the Lambarih Village area. Then the GNSS data collection was carried out in the field as many as 4 points in the Gampong Lambarih area, Aceh Besar using the control point or tie point of the CBDA station with doy 040 in Jantho. Each observation point was carried out for 30 minutes with a measurement time interval of 1 second. UAV data processing uses the Agisoft application and GNSS data processing using the HiTarget Geomatic Office (HGO) application and the BIG Website. The results showed that aerial photographs of UAVs bound with GNSS had a higher accuracy reaching in order of mm. Keywords: GNSS, UAV, Statik, BIG, HGO

Abstract

Kerentanan airtanah terhadap pencemaran dapat terjadi akibat adanya aktivitas manusia. Oleh karena itu, kualitas dan kuantitas airtanah perlu diperhatikan. Penerapan metode GOD (Groundwater Occurrence, Overlaying Lithology and Depth Of Groundwater) dilakukan untuk mengkaji kerentanan airtanah di Kota Banda Aceh, Provinsi Aceh. Metode GOD merupakan metode yang dilakukan dengan mengevaluasi tiga parameter yaitu jenis akuifer, jenis litologi diatas akuifer dan kedalaman muka airtanah. Penelitian ini bertujuan memetakan daerah yang berpotensi terjadi pencemaran berdasarkan tingkat kerentanan air tanah dengan menggunakan metode GOD, di Kota Banda Aceh. Hasil dari penelitian menunjukkan tingkat kerentanan airtanah intrinsik berdasarkan metode GOD berkisar pada nilai sedang sampai tinggi. Zona sedang berdasarkan metode ini ditunjukkan pada nilai indeks 0.45-0.5 yang mencakup beberapa daerah seperti Kuta Alam, Kutaraja, Meuraksa, Jaya Baru, Banda Raya, Lueng Bata, dan Baiturrahman. Dan daerah dengan indeks tinggi mencakup kecamatan Syiah Kuala dan Ulee Kareng dengan nilai 0.52-0.69. Kondisi litologi pada daerah penelitian menunjukkan tipe akuifer yang sejenis yaitu sistem akuifer aluvial. The vulnerability of contaminated groundwater caused by human activity. Thus, the quantity and quality of groundwater need more attention. The application of GOD (Groundwater Occurrence, Overlaying Lithology and Depth of Groundwater) methods is done for a review of groundwater vulnerability in Banda Aceh City, Aceh Province. The GOD method is a method by investigating three parameters, they are: type of aquifer, type of lithology above the aquifer, and depth of groundwater table. This study aims to map areas with potential contamination based on the level of groundwater vulnerability using the GOD method, in Banda Aceh City, Aceh Province. The result of the research shows that the level of intrinsic groundwater vulnerability in Banda Aceh by the GOD method range from moderate to high. Moderate groundwater vulnerability zone based on this method has an index value of 0.45 - 0.5 covers several areas, they are: Kuta Alam, Kutaraja, Meuraksa, Jaya Baru, Banda Raya, Lueng Bata, and Baiturrahman. And the high index value covers Syiah Kuala and Ulee Kareng with 0.52 - 0.69. The lithology of the studied area shows the same type of aquifer as an alluvial aquifer system. Keywords: groundwater vulnerability, GOD method, aquifer

Abstract

Tujuan penelitian ini adalah mengidentifikasi pengaruh variasi suhu larutan terhadap struktur lapisan yang terbentuk melalui metode elektroplating. Larutan elektrolit dibuat dengan campuran NiSO4, NiCL2,H3BO3, dan H2O. Elektroplating dilakukan selama 180 s dengan tegangan 4,5 V dan medan magnet 150 G pada arah sejajar permukaan katoda-anoda. Hasil penelitian menunjukkan suhu mempengaruhi ketebalan lapisan, arus listrik, jumlah zat yang terlepas dan terbentuk dan pH larutan. Lapisan paling tebal adalah sampel hasil deposisi pada suhu 40°C dengan ketebalan [(133,8 ± 0,9745)´ 10-5] cm pada pH 4,21. Kemudian yang paling tipis adalah sampel hasil deposisi pada suhu 60°C dengan ketebalan [(59,83 ± 0,6270) x 10-5] cm pada pH 4,18. Ketebalan lapisan yang terbentuk sebanding dengan jumlah zat terlarut dan jumlah arus yang mengalir selama pelapisan berlangsung. The purpose of this study is to identify the effect of temperature variations on the structure of the layers formed through the electroplating method. Electrolyte solution was made with mixture of NiSO4, NiCL2,H3BO3, and H2O. Electroplating was carried out for 180 s on the voltage of 4.5 V and magnetic field parallel to 150 G. The results showed temperature affects the thickness of the layer, electric current, the amount of released and formed substances and the pH of the solution. The thicknest of layer is according to the sample deposited at a temperature of 40°C with a thickness of [(133,8 ± 0,9745)x 10-5] cm at pH of 4.21. Then the thinnest one was according to the sample which was deposited at 60°C with a thickness of [(59,83 ± 0,6270) x 10-5] cm at pH of 4.18. The thickness of the layer is proportional to the amount of solute and the amount of current flowing during the coating. Keywords: Elektroplating, Flim Tipis, Cu/Ni, Suhu Larutan, Magnet Sejajar.

Litologi Formasi Anggota Padangtiji terdiri dari konglomerat, batulanau, batupasir gampingan dan batu gamping. Lingkup penelitian ini meliputi kajian tentang kondisi geologi permukaan dan analisis lingkungan pengendapan sedimen karbonat pada lokasi penelitian. Metode yang digunakan dalam penelitian ini yaitu pengambilan data langsung di lapangan dan menganalisis petrologi dan petrografi pada sampel batuan. Litologi pada lokasi penelitian terdiri dari 7 satuan yaitu guguran lava, lava andesit, lapili jatuhan piroklastik, tuf jatuhan piroklastik, konglomerat, batugamping terumbu dan batupasir gampingan. Lingkungan pengendapan sedimen karbonat yang terdapat pada lokasi penelitian terbentuk di laut dangkal (reef) pada kedalaman 0 m - 200 m di bawah permukaan laut. Zona fasies pengendapan batugamping pada lokasi penelitian terendapkan pada zona platform margin sands  dan organic buildups. Sedangkan zona fasies terumbu pada lokasi penelitian terdapat pada zona reef front. Montasik district consists of two formations, Gunungapi Lam Teuba Formation aged Late Pliocene – Late Pleistocene and Padangtiji Member aged Early Pliocene – Middle Pliocene. Lithology of Padangtiji Member consists of conglomerate, siltstone, carbonate sandstone, and limestone.  The scope of this research includes a study of surface geological conditions and depositional environmental analysis of carbonate sediment. The method used in this study is direct data collection in the field and analyzing petrology and petrography in rock samples. Lithology of the research area consists of lava drop, andesit, lapili pyroclastic, tuff pyroclastic, conglomerate, fosilliferous limestone, and carbonate sandstone.
