Perancangan Media Permainan Digital 2D untuk Pelajar SMU sebagai Edukasi Sejarah tentang Tiga Kerajaan Terbesar di Indonesia

Sejarah adalah kajian yang penting bagi pelajar dimana-mana karena dapat mengajari kita mengenai kesalahan yang dilakukan oleh manusia di masa lalu dan bagaimana cara untuk tidak mengulanginya. Akan tetapi, berdasarkan data kuesioner, lebih dari setengah responden menyatakan bahwa metode pembelajaran yang monoton membuat pelajaran sejarah kurang diminati untuk dipelajari. Bila metode pembelajaran ini tidak diubah, maka siswa tidak dapat mempelajari sejarah dengan baik dan tidak dapat mempelajari nilai yang dapat dianut dari sejarah. Oleh karena itu melalui Tugas Akhir ini, penulis hendak merancang media edukasi berupa permainan digital 2D tentang sejarah tiga kerajaan Indonesia, terutama mengenai Kerajaan Nusantara terbesar, yang merupakan era dimana Indonesia mulai berkembang, sebagai edukasi untuk anak SMU. Perancangan awal dimulai dengan melakukan penelitian dengan mixed methods. Metode pertama adalah kuantitatif yang dilakukan dengan menyebar kuesioner kepada pelajar dan metode kedua adalah kualitatif dengan melakukan wawancara dan studi literatur. Hasil dari tugas akhir ini adalah sebuah media interaktif berupa 2D Game yang bergenre platformer dengan cerita yang mendalami kerajaan Indonesia dan kejadian yang terjadi pada masa itu. Melalui perancangan media interaktif ini, diharapkan pelajar dapat mengenal lebih lanjut mengenai sejarah kerajaan Indonesia, terutama mengenai tokoh dan budaya kerajaan tersebut, dan mengambil nilai moral pentingnya

Perancangan 3D Asset dan Animasi dalam Game di Educa Studio

Sebagai salah satu syarat kelulusan, mahasiswa diwajibkan untuk melaksanakan program magang minimal 320 jam kerja. Magang memiliki arti yaitu proses pembelajaran yang diberikan oleh ahli melalui kegiatan di dunia nyata dengan proses melaksanakan dan menyelesaikan masalah nyata di sekitar. Penulis melaksanakan magang di Educa Studio yang berlokasi di Salatiga, dan melakukan tugas sebagai 3D Artist secara WFH (Work From Home). Educa Studio bergerak dalam bidang edutainment video games untuk anak-anak, dan merupakan lingkungan yang cocok untuk meningkatkan kemampuan penulis. Penulis memilih tempat magang di Educa Studio karena penulis tertarik dengan video game development yang berada di Educa Studio serta ingin mencoba bekerja secara WFH. Hambatan dan kedala yang dialami penulis dalam magang ini merupakan komunikasi antara penulis dan pembimbing sulit dan hanya dapat berkomunikasi melalui pembicaran online, serta respon yang kurang jelas dan cepat karena sifat magang online. Solusi untuk permasalahan ini adalah riset metode perancangan 3D secara mandiri, serta berkomunikasi dengan pembimbing pada waktu yang tepat agar dapat diberikan arahan yang lebih efektif. Selama berjalannya magang, penulis mempelajari banyak hal, seperi komunikasi antara pembimbing dan penulis, pelatihan penggunaan software Blender untuk perancangan 3D, alur kerja di dalam Educa Studio, dan metode perancangan 3D serta render yang baik

Asymptotics with Numerical Relativity: Gravitational Memory, BMS Frames, and Nonlinearities

With the recent commencement of the LIGO-Virgo-KAGRA (LVK) Collaboration's fourth observing run, the field of gravitational-wave physics is uniquely poised to collect even more accurate data from compact binary coalescences. Consequently, we will soon be able to perform more stringent tests of general relativity (GR). Because GR must, in some regime, be violated---either because the Universe is described by an alternative theory or because of the emergence of quantum effects---these tests of GR are crucial for unveiling new physics. Performing such tests, however, requires that our understanding of GR and gravitational waves is reliable. And, while there are many tools for unraveling Einstein's equations, the only one that is robust in every regime of GR is numerical relativity (NR): a means for computing accurate solutions to Einstein's equations with supercomputers. In this thesis, I highlight some recent and impactful advancements that have been incorporated into NR simulations of binary black holes. In particular, I show how a more robust procedure for calculating the radiative data at future null infinity from NR simulations, called Cauchy-characteristic evolution (CCE), produces waveforms that exhibit a not-yet observed prediction of GR colloquially referred to as memory. This phenomenon corresponds to the permanent net displacement that two observers will experience due to the passage of transient gravitational radiation. Memory is of particular interest in the testing GR and theory communities because of its relation to asymptotic symmetries and scattering amplitude calculations in particle physics. With these contemporary CCE waveforms, I provide explicit methods to calculate the various memory effects and I also comment on their relative magnitudes and detectability in the near future. Apart from this, I also demonstrate the importance of controlling the BMS freedoms of these waveforms, i.e., their frame freedom at future null infinity, for building waveform models as well as for extracting physics, such as GR's nonlinearities, from the ringdown phase of binary black hole mergers. As we start to enter the next phase of high-precision gravitational-wave astronomy, correctly modeling gravitational waves with NR simulations will play a crucial role in pushing Einstein's theory of relativity to its limits. It is the aim of this thesis to illustrate the importance of combining gravitational-wave theory and NR to not only improve our understanding of black holes and gravitational waves, but also further our prospects for unveiling the true nature of gravity within our universe.</p

Persistence of pharmaceutical compounds and other organic wastewater contaminants in a conventional drinking-water-treatment plant

In a study conducted by the US Geological Survey and the Centers for Disease Control and Prevention, 24 water samples were collected at selected locations within a drinking-water-treatment (DWT) facility and from the two streams that serve the facility to evaluate the potential for wastewater-related organic contaminants to survive a conventional treatment process and persist in potable-water supplies. Stream-water samples as well as samples of raw, settled, filtered, and finished water were collected during low-flow conditions, when the discharge of effluent from upstream municipal sewage-treatment plants accounted for 37–67% of flow in stream 1 and 10–20% of flow in stream 2. Each sample was analyzed for 106 organic wastewater-related contaminants (OWCs) that represent a diverse group of extensively used chemicals.Forty OWCs were detected in one or more samples of stream water or raw-water supplies in the treatment plant; 34 were detected in more than 10% of these samples. Several of these compounds also were frequently detected in samples of finished water; these compounds include selected prescription and non-prescription drugs and their metabolites, fragrance compounds, flame retardants and plasticizers, cosmetic compounds, and a solvent. The detection of these compounds suggests that they resist removal through conventional water-treatment processes. Other compounds that also were frequently detected in samples of stream water and rawwater supplies were not detected in samples of finished water; these include selected prescription and non-prescription drugs and their metabolites, disinfectants, detergent metabolites, and plant and animal steroids. The non-detection of these compounds indicates that their concentrations are reduced to levels less than analytical detection limits or that they are transformed to degradates through conventional DWT processes. Concentrations of OWCs detected in finished water generally were low and did not exceed Federal drinking-water standards or lifetime health advisories, although such standards or advisories have not been established for most of these compounds. Also, at least 11 and as many as 17 OWCs were detected in samples of finished water. Drinking-water criteria currently are based on the toxicity of individual compounds and not combinations of compounds. Little is known about potential human-health effects associated with chronic exposure to trace levels of multiple OWCs through routes such as drinking water. The occurrence in drinking-water supplies of many of the OWCs analyzed for during this study is unregulated and most of these compounds have not been routinely monitored for in the Nation’s source- or potable-water supplies. This study provides the first documentation that many of these compounds can survive conventional water-treatment processes and occur in potable-water supplies. It thereby provides information that can be used in setting research and regulatory priorities and in designing future monitoring programs. The results of this study also indicate that improvements in water-treatment processes may benefit from consideration of the response of OWCs and other trace organic contaminants to specific physical and chemical treatments

Near-surface trajectories off central and southern California

The near-surface circulation in the Santa Barbara Channel and off the coast of central and southern California is described based on 20 releases of drifters drogued 1 m beneath the surface from 12 sites within the channel at bimonthly intervals. This description includes small-scale features of the circulation which are not part of descriptions based on moored observations or of the statistics of the drifter releases. The eventual fate of drifters at long time intervals compared to the residence time in the channel (about 7 days) is also included. In the channel the trajectories document a persistent cyclonic circulation with a typical recirculation period between 3 and 5 days. In the spring, currents near the mainland are weaker than near the Channel Islands, and the overall flow is toward the southeast. Trajectories document the possibility for water parcels to leave the channel through the interisland passes. In the late fall and winter a poleward flow with velocities often exceeding 0.5 m s¯¹ is confined within 20 km of the mainland. Between these two seasons the cyclonic tendency is enhanced, although most of the drifters eventually migrate westward. The trajectories of drifters released at the same time from sites only 20 km apart can be remarkably different. Once the drifters migrate out of the channel, their trajectories can be grouped into a few patterns. In spring and summer, drifters tend to remain in the Southern California Bight. Their trajectories often remain close over extended periods, as if they were caught in convergence zones. In fall the drifters often are caught in a poleward current

Shape Space Methods for Quantum Cosmological Triangleland

With toy modelling of conceptual aspects of quantum cosmology and the problem of time in quantum gravity in mind, I study the classical and quantum dynamics of the pure-shape (i.e. scale-free) triangle formed by 3 particles in 2-d. I do so by importing techniques to the triangle model from the corresponding 4 particles in 1-d model, using the fact that both have 2-spheres for shape spaces, though the latter has a trivial realization whilst the former has a more involved Hopf (or Dragt) type realization. I furthermore interpret the ensuing Dragt-type coordinates as shape quantities: a measure of anisoscelesness, the ellipticity of the base and apex's moments of inertia, and a quantity proportional to the area of the triangle. I promote these quantities at the quantum level to operators whose expectation and spread are then useful in understanding the quantum states of the system. Additionally, I tessellate the 2-sphere by its physical interpretation as the shape space of triangles, and then use this as a back-cloth from which to read off the interpretation of dynamical trajectories, potentials and wavefunctions. I include applications to timeless approaches to the problem of time and to the role of uniform states in quantum cosmological modelling.Comment: A shorter version, as per the first stage in the refereeing process, and containing some new reference

Wind-Induced Vibration Energy Harvesting Using Piezoelectric Transducers Coupled with Dynamic Magnification

Flexible cylindrical structures subjected to wind loading experience vibrations from periodic shedding of vortices in their wake. Vibrations become excessive when the natural frequencies of the cylinder coincide with the vortex shedding frequency. In this study, cylinder vibrations are transmitted to a beam inside the structure via dynamic magnifier system. This system amplifies the strain experienced by piezoelectric patches bonded to the beam to maximize the conversion from vibrational energy into electrical energy. Realworld applicability is tested using a wind tunnel to create vortex shedding and comparing the results to finite element modeling that shows the structural vibrational modes. A crucial part of this study is conditioning and storing the harvested energy, focusing on theoretical modeling, design parameter optimization, and experimental validation. The developed system is helpful in designing wind-induced energy harvesters to meet the necessity for novel energy resources
