City Form

<p>Koridor adalah lahan memanjang yang membelah kota/kawasan atau sebuah lorong membentuk fasade bangunan berderet dengan lantai atau ruang kota bergerak dari ruang satu ke ruang lainnya (Wiharnanto dalam (Sumartono, 2003)). Koridor berfungsi sebagai jalan sekaligus wadah berinteraksi (Kurokawa, 1997). Koridor Jalan Slamet Riyadi yang berada di pusat Kota Surakarta terjadi perkembangan aktivitas perkotaan juga berfungsi sebagai ruang interaksi sosial. Adanya keselarasan antara aktivitas masyarakat dengan ruang yang mewadahinya menimbulkan suatu karakteristik yang dapat diamati berdasarkan Teori Good City Form (Lynch, 1981). Penelitian ini bertujuan untuk mengetahui karakteristik Koridor Jalan Slamet Riyadi sebagai ruang interaksi sosial Kota Surakarta berdasarkan Teori <em>Good City Form</em>. Menggunakan jenis penelitian deskriptif kualitatif untuk mengeksplorasi isu dengan pendeskripsian secara detail sehingga didapatkan gambaran mendalam tentang karakteristik koridor jalan berdasarkan Teori <em>Good City Form</em> di lokasi terkait. Pendekatan penelitian dilakukan secara deduktif dengan peneliti akan melakukan penelitian berangkat dari teori mengenai koridor, aktivitas di ruang publik, dan <em>Good City Form Theory</em> untuk terjun ke lapangan melakukan pencarian data yang dibutuhkan. Koridor Jalan Slamet Riyadi memenuhi kriteria bentuk yang baik sebagai ruang interaksi Kota Surakarta berdasarkan Teori <em>Good City Form</em>, juga memiliki karakteristik fisik (<em>physical characteristic</em>) dan karakteristik spasial (<em>spatial characteristic</em>) yang berbeda dari jalan perkotaan lainnya. Karakteristik fisik berupa jalan besar yang membelah pusat Kota Surakarta dengan pembagian jalur lalu lintas yang beragam mulai dari jalur lambat untuk becak dan sepeda, jalur kendaraan bermotor berdampingan dengan rel kereta api aktif, dan citywalk sebagai jalur pejalan kaki dengan dilengkapi deretan bangunan untuk perdagangan dan jasa serta pepohonan rindang. Sedangkan karakteristik spasial berupa jalan perkotaan yang memiliki nilai sejarah diantaranya sebagai pembatas daerah kekuasaan antara Keraton Kasunanan dan Keraton Mangkunegaran serta memiliki peranan sangat penting bagi Kota Surakarta selain sebagai penghubung menuju pusat Kota Surakarta, juga menjadi wadah penyelenggaraan beragam aktivitas bagi masyarakat juga event tahunan Kota Surakarta.</p><p><strong>Kata kunci: Karakteristik; Koridor Jalan Slamet Riyadi; Ruang Interaksi Sosial; Teori Good City Form</strong></p>

Background:Moringa (Moringaoleifera Lam.) Is a plant of high nutritional value, grows scattered in the tropics and sub-tropics, but utilization is still low. Each section has its benefits Moringa one part is the Moringa leaves contain a high calcium. In 100 grams of material, fresh Moringa leaves contain as much as 440 mg of calcium in the form of flour whereas if it contains as much as 2,003 mg of calcium. One of its use in the manufacture of flakes added. Objective: Know the difference physical harateristi, organoleptic characteristic and calcium levels in flakes variations addition of Moringa leaf powder. Methods: The study is a randomized experimental design with simple, includes four kinds of treatments, two replications with two experimental units. Observations of physical characteristic were analyzed by descriptive, the organoleptic characteristic of data analysis using statistical test Kruskal-Wallis continued Mann-Whitney and methods of test calcium content using permanganometri then the data were analyzed descriptive. Results: The physical characteristics of flakes greenish-yellow, slightly fragrant aroma typical of flakes, rather unpleasant taste typical of Moringa leaves and a slightly crunchy texture. Organoleptic characteristics the color of flakes with moringa leaf powder 5%, the aroma of the flakes without addition moringa leaf powder, the flavour of flakes with additions moringa leaf powder 5% and the texture of flakes with additions moringa leaf powder 7,5% most prefered panelist and high levels calcium of flakes with additions 10% moringa leaf powder. Conclusion: There is a difference variations addition of moringa leaf powder on physical, organoleptic characteristic (color) and the level of calcium flakes.Flakes with the addition of 5% moringa leaf powder is the most prefered panelist.   Keywords:Moringa Leaf Flour, Flakes, Physical characteristic, organoleptic, Calcium

Understanding the magnitude and distribution of the mixes of the near-ground carbon dioxide (CO2) components spatially (related to the surface characteristics) and temporally (over seasonal timescales) is critical to evaluating present and future climate impacts. Thus, the application of in situ measurement approaches, combined with the spatial interpolation methods, will help to explore variations in source contribution to the total CO2 mixing ratios in the urban atmosphere. This study presents the spatial characteristic and temporal trend of atmospheric CO2 levels observed within the city of Wroclaw, Poland for the July 2017–August 2018 period. The seasonal variability of atmospheric CO2 around the city was directly measured at the selected sites using flask sampling with a Picarro G2201-I Cavity Ring-Down Spectroscopy (CRDS) technique. The current work aimed at determining the accuracy of the interpolation techniques and adjusting the interpolation parameters for estimating the magnitude of CO2 time series/seasonal variability in terms of limited observations during the vegetation and non-vegetation periods. The objective was to evaluate how different interpolation methods will affect the assessment of air pollutant levels in the urban environment and identify the optimal sampling strategy. The study discusses the schemes for optimization of the interpolation results that may be adopted in areas where no observations are available, which is based on the kriging error predictions for an appropriate spatial density of measurement locations. Finally, the interpolation results were extended regarding the average prediction bias by exploring additional experimental configurations and introducing the limitation of the future sampling strategy on the seasonal representation of the CO2 levels in the urban area.

Abstract We investigate a delayed epidemic model for the propagation of worm in wireless sensor network with two latent periods. We derive sufficient conditions for local stability of the worm-induced equilibrium of the system and the existence of Hopf bifurcation by regarding different combination of two latent time delays as the bifurcation parameter and analyzing the distribution of roots of the associated characteristic equation. In particular, we investigate the direction and stability of the Hopf bifurcation by means of the normal form theory and center manifold theorem. To verify analytical results, we present numerical simulations. Also, the effect of some influential parameters of sensor network is properly executed so that the oscillations can be reduced and removed from the network.

AbstractIn this paper, we are concerned with a delayed smoking model in which the population is divided into five classes. Sufficient conditions guaranteeing the local stability and existence of Hopf bifurcation for the model are established by taking the time delay as a bifurcation parameter and employing the Routh–Hurwitz criteria. Furthermore, direction and stability of the Hopf bifurcation are investigated by applying the center manifold theorem and normal form theory. Finally, computer simulations are implemented to support the analytic results and to analyze the effects of some parameters on the dynamical behavior of the model.
