Abstract

Earthquake is a natural occurrence in which energy is released and propagated from the earth to the ground surface. The effects of the earthquakes include failure of building, landslides, tsunamis and so on. Mitigation actions are required to reduce the number of people killed or injured as a result of earthquakes. Assessing the vulnerability of buildings to earthquakes is one of the mitigation efforts. The Hazus Method is used to assess the vulnerability of a building. This method requires information such as: building typology and seismic activity at the location to be studied. The goal of this study is to assess the level of earthquake susceptibility based on the structure type in Manokwari Selatan Regency. Concludingly, the building typology in Manokwari Selatan Regency will be divided into five categories of vulnerability, specifically: no damage, light damage, moderate damage, major damage, and collapse. Based on observations, there are several typologies of the existing buildings in the Manokwari Selatan Regency, namely: wooden light frames (W1), Steel Moment Frame (S1L), Concrete Moment Frame C1L) and Reinforced Masonry Bearing (RM1L). The results of the analysis show that the typology Steel Moment Frame (S1L) has the possibility of light, moderate, heavy damage, collapse and no damage, respectively 7.13%, 32.66%, 39%, 18.13%, and 3.07%; the typology Concrete Moment Frame (C1L) are 8.39%, 34.91%, 36.84%, 16.35%, and 3.51% respectively; the typology wooden light frames (W1) are 18.16%, 47.89%, 21.18%, 10.03%, and 2.74%; the typology Reinforced Masonry Bearing (RM1L) has a probability of 10.76%, 34.45%, 36.06%, 13.14%, and 5.59%. Keywords: Earthquake, Building Typology, Building Vulnerability, Hazus Method.

Abstract

The increasing demand for sand and stone materials has resulted in competitions between mining companies in order to meet the need of the material for construction activities, from which it results in conflicts between two parties, two people, or groups of people. Part of the mathematical programming technique used to analyze the decision-making process of competition between two or more parties is Game Theory. The application of game theory is to produce the best strategy that will be used by a company to optimize the marketing of gravel fraction. Instruments or tools used in the research is a questionnaire that includes improving product quality, affordable pricing, improving service quality, establishing an effective corporate work process, and determining the place of inventory. The result is arranged in the form of a payoff matrix and analyzed using the Game Theory, that indicates the competition between PT X and PT Y. The analysis results show that the implementation of those strategies is the best way that can optimize marketing of gravel fraction, so that it can improve the position of profit or loss got saddle point from competition between PT X and PT Y, which is 11. The results also confirm the increase of profit of PT X, from 10 to 11 by applying effective work processes (probability 5:1). In addition, the loss of PT Y could decrease from 12 to 11 by applying strategies to improve the product quality of gravel fraction and determining the stock of the fraction (probability 1:1).

Abstract

The main air transportation hub for the city of Manokwari is Rendani Airport. The number of passengers and flights is currently increasing from year to year. Therefore, this study aims to determine the characteristics of car parking, especially at Rendani Airport. This study conducted a direct field survey by recording entry and exit tickets to collect vehicle data. The data collected shows that the highest parking volume is 131 vehicles, parking accumulation is 93 vehicles, parking lasts between one and fifteen minutes, the highest parking turnover rate is 0.873 vehicles/parking area, and the average parking index is 39.2. %. Whereas for two-wheeled vehicles, the highest parking turnover rate was 0.391 vehicles/parking area, the highest parking volume was 43 vehicles, the highest parking accumulation was 52 vehicles, and the average parking index was 34.0%. Vehicle parking duration ranges from one to fifteen minutes. This shows that the parking index is less than 100%, this shows that the vehicle parking at Rendani Airport can still accommodate requests determined from the results of calculating the characteristics of vehicle parking at Rendani Airport, the average car parking index is 39.2 percent. and 34.0% for motorcycles in 60 minute intervals. Director General of Land Transportation Standard No: 272/HK.105/DRJD/96 mentions Guidelines for Planning and Operation of Parking Facilities. On two-wheeled vehicles, the size and pattern meet the requirements. The angle and width of the vehicle compartment meet the requirements for four-wheeled vehicles, but the maneuverability space is not up to standard.

Abstract

Road is one of the important and influential transportation infrastructures for the development of an area. This development will affect the volume of traffic which will put an increasing load on the pavement so that this has an impact on the functional decline of the road. The functional management of the road becomes a measure in the assessment which becomes a reference for determining the type of evaluation program that must be carried out, one of which is road roughness. In this study, the evaluation of the level of road leveling using the International roughness index (IRI) method as an indicator in the assessment ofan roads produced from the Roughometer III tool. Evaluation is carried out to determine the unevenness of road sections and road handling carried out for the level of road damage. From the calculation results, it is known that the condition of the level of equality on the ruas of the Yos Sudarso Manokwari road L line (left), 76.53% Good, 23.47% Fair, and R lane (right), 4.69% Excellent, 67.14% Good, 23.47% Fair, 4.69 % Poor . For ruas road Trikora Wosi Manokwari line L (left), 58.63% Good, 41.37%, and line R (right), 3.66% Excellent, 74.35% Good, 18.32% Fair, 3.66% Poo. On the Drs. Esau Sesa Manokwari road section L line (left), 3.66% Excellent, 7.68% Good, 63.97% Fair, 25.79% Poor 2.56% Bad and R lane (right), 13.00% Good , 76.77% Fair , 10.24% Poor
