Abstract

Waves and currents can remove sand from the coastal areas that caused beach erosion. Beach erosion needs to be handled by building breakwater. Rubble mound breakwater is chosen to dissipate the wave energy. Rubble mound structures are widely used throughout the world; so naturally, stability tests of rubble mound structures are the most frequently conducted coastal structure model. Two-dimensional rubble mound structure physical model is carried out in a flume. The armor layer facing the seaward uses tetrapods that are placed randomly and the core layer is set to be stable by using geotube. Three different slopes of rubble mound model facing the seaward is applied, i.e., 1:1.5, 1:2, and 1:2.5, respectively. There are also four different water levels used, i.e., 38 cm, 54 cm, 63 cm, and 70 cm. The measured parameters of this study are the wave height and wave period in front of and behind the breakwater structure. The analysis that can be done is the wave absorber and transmission waves. The stability of the structure can be observed in the form of displacement armor testing on the breakwater and at toe for a wide variety of slope and water level variations.

Abstract

The general definition of gasification is thermo-chemical process of solid fuel form which becomes gas fuel with limited supply of O2 and it produces CH4, H2, CO, and impurity compound such as H2S, CO2, and tar. The objective of this research was to determine the influence of air velocity toward combustion temperature in order to invent the best values of air velocity for chopped wood gasification process.The research was commenced by preparing chopped wood as material for downdrft gasififier. Subsequently, glasswool was utilized as gasifier isolator in the gasification process to isolate heat in order to obtain the best heat efficiency. In the gasification processes, variaton of air speed was applied. The sample was chopped wood with gasification furnace in which the results of combustion temperature and combustion time were analyzed.The result indicated that the highest temperature was not depends on the fastest air flow velocity. Instead, it required a precise air flow velocity to gain the highest temperature. It was evidenced that the highest temperature gained was at 6200 C with v = 5.6 m/s air flow velocity. The longest gasification process was 13 minutes at v = 7.6 m/s and the fastestgasification process was 11 minutes at v = 5.6 m/s.

Abstract

Walls, even though being included in non-engineering building element, actually have the strength and stiffness. In this study, the wall elements will be analyzed regarding the influence in a system of reinforced concrete frame. The other side of this research is the adoption of high-rising building technology in the use of shear wall elements into earthquake-safe homes.This technology is to prevent the wall from quick collapse when exposed to seismic forces are by strengthening the areas diagonally. Diagonal area is an area where there will be the greatest shear force effects, and it is characterized by the appearance of cracks or even splitting on the diagonal area. The modeling of reinforced concrete structures is applied to SAP2000 to open frame and frame with concrete panels as filler. This is modeled as bracing representing an area of wall. There are 37 test objects of open frame and frame with wall concrete panels as filler (100x50x7), with diagonal reinforcement/bracing of the group of steel reinforcing. SAP2000 analysis results indicate that the structure with wall panels have a higher value than the capacity of open frame structure. Laboratory experimental data with compression test showed increased values up to 215.36% on the frame with wall panel, an increase of 271.99% on the frame wall panels with diagonal steel reinforcement. Flexural test showed increased values up to 37.73% on the frame with wall panel and an increase of 260.76% on the frame wall panels with diagonal steel reinforcement. The addition of diagonal reinforcement elements is conducted to divide the force received by the wall and to increase the strength of the wall and the stiffness of the structural system.

Abstract

Boron neutron capture therapy (BNCT) is a selective targeting cancer therapy method which is by radiating epithermal neutron beams to a tumor which has been injected by boron-10 compound. The implementation of this method requires 2 (two) key elements, namely the boron-10 compound and the irradiating neutron beam of epithermal energy level. The neutron source used in this research was 13 MeV 1mA cyclotrons which have been developed by Indonesia National Nuclear Energy Agency. This paper was preoccupied in beam shaping assembly (BSA) target system. BSA target system is used to convert the proton produced by cyclotron into neutron. IAEA generated a recommendation for BNCT neutron beam quality, one of them was epithermal neutron flux which is higher than 109

Abstract

Samin is one of watersheds located in the districts of Karanganyar and Sukoharjo, Central Java, Indonesia. Samin is a part of Bengawan Solo watershed that is classified into one of 282 Indonesian watersheds which are in critical condition. Research about vegetation analysis of Samin watershed as conservation efforts have been done before and resulted in structure of lower crop community (LCC) and tree vegetation. The purpose of this study was to analyze potential plants, both LCC and trees, in Samin watershed that could be developed as a vegetative water and soil conservation. The list of plants that were potentially developed as a vegetative conservation obtained from the research before about analysis structure and composition of vegetation in Samin watershed and literature review. The result of this research showed that there were several plants with the highest Important Value Index (IVI) and that can be developed for vegetative soil and water conservation. In tree vegetation, there are Tectona grandis, Delonix regia, Switenia mahagoni, Cassia siamea, and Samanea saman. These tree plants have a big canopy that can retain rain water through several mechanismssuch as interception, reducing direct flow, and producing litter layer. In LCC vegetation, there were Mimosa pudica, Ageratum conyzoides, Tridax procumbens, Oplismenus burmanii, Chloris barbata, and Axonopus compressus. Grass vegetation could withstand runoff and increase infiltration.

Abstract

Background: For many years Kentucky has had the nation’s highest lung cancer incidence. Kentucky is one of the thirteen states in Appalachia in which the difference in wealth is a key determinant of health since residents of Appalachia do not have access to the same financial resources as the rest of the US population. In this study, the value of lung cancer treatment for a medically underserved population (Appalachia) would be evaluated based on health insurance type and treatment pattern. Methodology: Data for lung cancer cases diagnosed between 2000 and 2011 were obtained from the Kentucky Cancer Registry (KCR). The cohort included 49,512 patients who met the following inclusion criteria. Patients were classified into two distinct groups based on county location: Appalachian and Non-Appalachian. Chi-square, Cox survival regression analysis, and Kaplan Meier survival trend were performed to identify variables affecting treatment and survival. Result: The analysis evaluated 49,512 patients from KCR. For all population, sex (p<.0001), age group (p<.0001), Stage (p<.0001), insurance type (p<.0001) and county (p<.0001) were significantly associated with the type of treatment. Conclusions: Eventhough the strongest predictors for survival in lung cancer are age and cancer Stage, health insurance does have a significant impact on improving the survival rate. Overall, early diagnosis and timely follow up are imperative for improving the value care in lung cancer treatment

Abstract

Indonesia is located in a strategic location between Indian and Pacific Ocean. Indonesia has water territory more than land territory with approximately 3:2 in ratio. In that vast area, there are many cultural heritages from old history, both in land and underwater. Cultural heritages found in both locations have a connection. Until recently, the government has attempted to reveal the past from underwater cultural heritage through survey and exploration. Many invaluable cargoes were salvaged from the underwater wreckages. Exploration and salvage are done by private company with the permit from the National Committee for Salvage and Utilization of the Valuable Object of the Sunken Ship (PANNAS BMKT). However, illegal exploration and salvage persists in the practice. Conservation efforts that include protection, development and utilization to the underwater cultural heritage had not been maximal; therefore, salvage, pilferage, and vandalism still occur. This paper would try to give an alternative for the utilization of underwater cultural heritage through a maritime museum in its natural state (in-site conservation). Museum is one institution that protects, develops and utilizes cultural heritages, and communicates them to the visitor.
