Pengembangan Masyarakat Desa Tertinggal Berbasis Keterpaduan dan Otonomi Daerah (Studi Pemberdayaan Masyarakat di Kecamatan Gedangsari Gunung Kidul)
Tulisan ini merupakan kajian atas hasil penelitian yang dimaksudkan untuk menggambarkan kawasan desa tertingggal di Gedangsari, salah satu kecamatan di Gunung Kidul. Kajian ini tentang desa tertinggal yang sebagian besar didominasi oleh perbukitan dan berkapur ini difokuskan pada aspek social ekonomi hingga pemberdayaan masyarakat khususnya keterlibatan masyarakat dalam pembangunan. Dengan menggunakan pendekatan kualitatif yang didahului dengan pra survey, metode indepth interview, metode penjajakan cepat mengenai desa (Participatory Rural Appraisal) serta penerapan Focus Group Discussion diharapkan kajian pemberdayaan masyarakat menjadi lebih komprehensif Penggabungan beberapa metode ini digunakan untuk menjaring data-data yang diperlukan serta kemungkinan tercapainya dialog antara kelompok-kelompok masyarakat baik di tingkat kecamatan maupun desa. Sumber data adalah para tokoh masyarakat, aparat pemerintahan serta warga masyarakat yang tergabung dalam unit pemberdayaan. Data yang dikumpulkan diklasifikasi sesuai jenis dan sifatnya, direduksi dan dianalisis serta diintepretasikan secara deskriptif kualitatif hingga tertuang dalam tulisan ini. Beberapa butir temuan penting dari kajian ini bahwa masyarakat yang berbukit, berkapur dan sebagian besar adalah petani (1) memiliki kesadaran akan ketertinggalannya sehingga secara bersama-sama dalam kelompok, swadaya maupun bersama aparat pemerintah desa melakukan deversifikasi USAha dengan berbagai cara antara lain peningkatan ketahanan pangan, peningkatan USAha produktif bidang kerajinan, serta pemberdayaan melalui system kelembagaan (organisasi social), paguyupan, pemuda kelompok petani serta kelembagaan untuk peningkatan partisipasi masyarakat. (2) Keterpaduan dan Otonomi Daerah sebagai bagian proses pemberdayaan tidak sepenuhnya dapat diimplementasikan oleh karena beberapa kendala antara lain: pemahaman pada kedua konsep tersebut berbeda-beda, belum adanya penjabaran atas model itu serta kesenjangan antara banyaknya program yang belum terimplementasi dengan rencana strategis yang tersusun secara bottom up. Di sisi lain kompleksitas penerapan otonomi daerah secara sosio cultural menjadi kendala implementasi keterpaduan dan otonomi daerah Namun demikian otonomi dan keterpaduan bukanlah menjadi isu penting bagi proses pemberdayaan oleh karena model pengembangan desa tertinggal melalui pemberdayaan individu maupun dinamika kelompok merupakan perpaduan kombinatif yang sustainabl
Konsep Perancangan Museum Gula di Surabaya
Indonesia telah dikenal sebagai produsen gula semenjak era penjajahan Belanda dan sempat menduduki peringkat kedua di dunia. Akan tetapi, setelah kemerdekaan, produktivitas gula justru mengalami penurunan bahkan pada masa kini Indonesia menjadi negara yang mengimpor gula dari luar negeri. Kebutuhan untuk mengenang sejarah dan masa kejayaan gula di Indonesia menjadi latar belakang dari proyek ini. Proyek museum gula di Surabaya ini dirancang memberikan informasi dan edukasi kepada pengujung mengenai sejarah perkembangan gula dari masa keemasan pada era penjajahan Belanda hingga masa kini. Sejarah dihadirkan dalam desain museum melalui tata ruang yang kronologis dan sirkulasi ruang yang berurutan. Untuk mendukung kesan kronologis, maka digunakan pendalaman karakter ruang. Ruang-ruang dalam museum dirancang tidak hanya sebagai diorama pameran perkembangan gula, namun juga menampilkan suasana dan karakter ruang yang sesuai dengan kronologis sejarah gul
Destruction of chain-superconductivity in YBa_2Cu_4O_8 in a weak magnetic field
We report measurements of the temperature dependent components of the
magnetic penetration depth {\lambda}(T) in single crystal samples of
YBa_2Cu_4O_8 using a radio frequency tunnel diode oscillator technique. We
observe a downturn in {\lambda}(T) at low temperatures for currents flowing
along the b and c axes but not along the a axis. The downturn in {\lambda}_b is
suppressed by a small dc field of ~0.25 T. This and the zero field anisotropy
of {\lambda}(T) likely result from proximity induced superconducting on the CuO
chains, however we also discuss the possibility that a significant part of the
anisotropy might originate from the CuO2 planes.Comment: 5 page
Sonic interactions in virtual environments
This book tackles the design of 3D spatial interactions in an audio-centered and audio-first perspective, providing the fundamental notions related to the creation and evaluation of immersive sonic experiences. The key elements that enhance the sensation of place in a virtual environment (VE) are: Immersive audio: the computational aspects of the acoustical-space properties of Virutal Reality (VR) technologies Sonic interaction: the human-computer interplay through auditory feedback in VE VR systems: naturally support multimodal integration, impacting different application domains Sonic Interactions in Virtual Environments will feature state-of-the-art research on real-time auralization, sonic interaction design in VR, quality of the experience in multimodal scenarios, and applications. Contributors and editors include interdisciplinary experts from the fields of computer science, engineering, acoustics, psychology, design, humanities, and beyond. Their mission is to shape an emerging new field of study at the intersection of sonic interaction design and immersive media, embracing an archipelago of existing research spread in different audio communities and to increase among the VR communities, researchers, and practitioners, the awareness of the importance of sonic elements when designing immersive environments
The Dynamic Grid: Time-Varying Parameters for Musical Instrument Simulations Based on Finite-Difference Time-Domain Schemes
Several well-established approaches to physical modeling synthesis for musical instruments exist. Finite-difference time-domain methods are known for their generality and flexibility in terms of the systems one can model but are less flexible with regard to smooth parameter variations due to their reliance on a static grid. This paper presents the dynamic grid, a method to smoothly change grid configurations of finite-difference time-domain schemes based on sub-audio–rate time variation of parameters. This allows for extensions of the behavior of physical models beyond the physically possible, broadening the range of expressive possibilities for the musician. The method is applied to the 1D wave equation, the stiff string, and 2D systems, including the 2D wave equation and thin plate. Results show that the method does not introduce noticeable artefacts when changing between grid configurations for systems, including loss.Several well-established approaches to physical modeling synthesis for musical instruments exist.

Real-Time Implementation of Non-Linear Physical Models with Modal Synthesis and Performance Analysis
Modal decomposition is a popular analysis approach involving the description of a target system via a bank of resonant oscillators called modes. Early sound synthesis frameworks successfully exploited this idea for the simulation of vibrating objects such as bars, plates and strings. While popular, modal synthesis is often applied to linear systems, since the modes become densely coupled in systems presenting distributed or multiple nonlinearities. In this work, the modal approach is used for the simulation of nonlinearly connected systems. When the nonlinearity is of cubic type, a suitable energy-stable modal update can be derived requiring the solution of a single linear system at each time step. A working plugin written in the C++ programming language is presented. Moreover, the performance of the plugin is analysed considering systems of different dimensions, defining the current limits for a real-time application of these models. The analysis also revealed a linear correlation between the number of modes which compose the systems and the CPU usage necessary for their real-time computation
Multisensory plucked instrumentmodeling in unity3D: FromKeytar to accurate string prototyping
Keytar is a plucked guitar simulationmockup developed with Unity3D that provides auditory, visual, and haptic feedback to the player through a PhantomOmni robotic arm. Starting froma description of the implementation of the virtual instrument, we discuss our ongoing work. The ultimate goal is the creation of a set of software tools available for developing plucked instruments in Unity3D. Using such tools, sonic interaction designers can efficiently simulate plucked string prototypes and realize multisensory interactions with virtual instruments for unprecedented purposes, such as testing innovative plucked string interfaces or training machine learning algorithms with data about the dynamics of the performance, which are immediately accessible from the machine
