Abstract

Site quality is one of the main information needed in forest stand management. Site quality classes need to be evaluated every certain period because the quality of forest stands may change as a result of management applied. This study describes the use of very high-resolution imagery derived from unmanned aerial vehicle (UAV) for estimating the site quality of teak (Tectona grandis). The UAV imagery used was taken from 400 m above datum (the average land surface elevation) with ground spatial resolution of 15 cm. Site quality estimation models was built using discriminant analysis. The study found that the best accuracy from discriminant function using multiple variables canopy density (C) and average of crown diameter (D_c ̅) is 60.9%.

Abstract

Study on eggs properties, based on electrical measurement (conductance and capacitance) was carried out using alternating current signal on frequency variation from 10 Hz to 100 kHz. The electrical properties correlated to physical properties of eggs i.e haugh unit, pH and viscosity. The albumen and yolk of native eggs, which were placed in the cell system from acrylic and electrode plate conductor of cuprum, were used as samples. Hi LCR Tester Hioki with dual probe (modified from four probes) was used to measure electrical properties of samples. This equipment was provided with fixed current source but varies in frequency. The conductance of yolk and albumen increased exponentially if frequency signal was boosted up. The electrical conductance range of albumen was higher than yolk on all frequencies. The capacitance property decreased if frequency signal was boosted up. The decrease was exponential especially at frequency under 100Hz. The albumen capacitance was lower than yolk. The viscosity of yolk and albumen during storage was decreasing. The value of pH was not affected. The pH of albumen was between 9 and 10, and yolk was about 6. Multiple regression method was used to get empiric equation of electrical conductance, capacitance, HU and viscosity. The best correlation between electrical parameter and physical properties is conductance equation of HU and viscosity at 1 kHz. Key words: electrical properties, conductance, capacitance, native chicken, egg

Abstract

Augmented reality is a term for combining real-world environment with virtual worlds. Augmented reality is becoming very popular today because besides interesting, also can be displayed in realtime. In general, augmented reality adds a digital object in reality with reference to specific objects in the real world, for example by using a marker. Therefore, in this thesis aims to create an application that displays a 3D object that contains information about the network components and the workings of TCP / IP by making use of the concept of augmented reality marker technique. A marker is a reference object in the real world as a marker so that the information can be displayed. The marker is made to function to call the 3D objects appear on the screen smartphone that uses the technique of introduction of basic colors of red, green and blue. The method used consists of several stages of research, namely data collection, analysis and system design and system implementation. Data collection method used is literature. Methods of analysis and design of systems using the Unified Modeling Language (UML). The programming language used for software development are C # (C-Sharp) with Unity applications and software SketcUp to create 3D objects as well as Android SDK to convert the file into the form of android. This application is successfully created by displaying a 3D object that can make users excited to get to know the physical network components and requires only an internet connection to download the initial marker.

Abstract

The demand for accessible parking services and facilities are growing in the University of Singaperbangsa Karawang (Unsika). This occurred due to the increasing number of vehicles need parking spaces. Some problems can happen because of scrambling over the space, the improper of parking lot building, the ineffective actions in allocating and checking the traffic signs, and the unavailability of traffic signs. The focus of this research was the campus community who use the parking lot. They became the object of the research. The data analysis was used to determine the level of the satisfaction of the campus community towards the service quality and parking facilities in Unsika using the Wilcoxon Signed Rank Test method with Statistical Product and Service Solutions (SPSS) application. The results showed that the campus community was complaining about the quality of service and parking facilities. The perceptions were given in the form of negative perceptions because it was not in line with expectations. The respondents were hoping that the university would pay attention to the quality of services and facilities.

Abstract

Meriam 57 mm Retrofit merupakan salah satu alat utama sistem persenjataan (alutsista) yang dimiliki satuan Batalyon Arhanudse untuk menghalau serangan udara. Pada pergeseran meriam dari pangkalan menuju ke medan latihan/tempur atau sebaliknya, perlu dilakukan perubahan sikap angkut pada meriam terlebih dahulu. Perubahan sikap tempur ke sikap angkut pada meriam masih menggunakan pompa manual, yaitu mengayunkan tuas pompa manual untuk mengalirkan minyak hidrolik dari tangki ke silinder bogie. Piston di dalam silinder bogie akan naik sehingga terjadilah perubahan dari sikap tempur ke sikap angkut. Penggunaan pompa manual ini kurang efektif karena selain menguras tenaga, waktu pemompaan juga relatif lama ± 1 menit. Berdasarkan hal tersebut diatas, telah dirancang sistem hidrolik untuk perubahan sikap angkut pada meriam tersebut yang terdiri dari gear pump, hydraulic hose, katup-katup, inverter, motor listrik AC. Dengan memanfaatkan sumber listrik dari baterai meriam yang diubah dari arus DC menjadi arus AC oleh inverter sehingga menggerakkan motor listrik. Ketika motor listrik dihidupkan gear pump ikut berputar karena satu poros dengannya. Gear pump akan menghisap minyak dari tangki dan memompanya kedalam silinder bogie melalui hydraulic hose dan katup-katup yang terpasang. Sehingga terjadilah perubahaan sikap angkut yang lebih efesien tenaga dan waktu. Kata kunci : meriam, silinder bogie, gear pump, motor listrik.
