Abstract

The increase in vehicle ownership number will affect the increase in traffic flow, which will usually result in congestion on the road network. This phenomenon causes vehicles to tend to travel close to one another (platoon). Characteristics used in describing the platoon phenomenon are the distance between vehicles (headway), average speed, and the number of vehicles in the platoon. This study is to analyzes the effect of variations in the leader and platoon length on vehicle speed. This research was conducted on Padang – Bukittinggi Road. Based on the Decree of the Minister of PUPR No: 248/KPTS/M/2015, Padang - Bukittinggi Road is categorized as a primary arterial road. This research used the primary data, a field survey, by recording vehicle traffic flow (traffic platoon) for two days. A distance of 50 meters is taken to determine the speed, and the time is measured with a stop program. The average headway on weekdays is 1.32 seconds and on holidays is 1.47 seconds. The size of the platoon and the type of platoon leader have a significant effect on the average speed of the vehicle in the platoon if the headway is  ≤ 2 seconds. At the addition of one vehicle in the platoon, which can change the vehicle's average speed, follows the equation y = -4.30x + 67.09.

Abstract

Satellite Technology Center – LAPAN would develop a constellation of 9 communication satellites in a low equatorial orbit. These satellites would perform as data collection platforms for many sensors that spread across the Indonesian territory. The data from the sensors will be downlink to Indonesia’s ground stations in real-time. This research aims to analyze the power budget of those satellites to decide how many solar panels and batteries are required to perform their mission. The method in this research began by calculating the power requirements of each mission per orbit period to estimate power consumption and calculate the power generated by the solar panels. The results of these calculations will be implemented to the power system design to find the satellite solar cells/ panels arrangement and battery capacity allocation. To minimize the development time and cost, the solar array design in this study considers the utilization of previous solar panel design of LAPAN-A series satellites as a design constraint. This study shows the configuration of 3 body-mounted solar panels and 2 deployable solar panels could support the mission operation of communication satellite in the low equatorial orbit. For energy storage, these satellites should be equipped with 28 V Li-ion in the 8Sx3P configuration.

Abstract

Honeycomb sandwich structures are widely used in space applications due to their exceptional performance. Extensive research has been conducted on the response of honeycomb structures to various external loads. The out-of-plane strength, including compression and tensile properties, is a critical aspect of honeycomb structures. Despite some experimental and numerical studies, research specifically addressing the tensile direction, such as flatwise tensile testing in honeycombs, remains limited. This testing focuses on the bond strength between the face sheets and the honeycomb core, as well as the tensile strength of the core itself. Utilizing finite element analysis (FEA) has proven effective for characterizing honeycomb structures under various load conditions. However, the complex geometry of the core requires an enormous number of elements, increasing computation times. Thus, simplifying the model by replacing the hexagonal geometry with a homogenized solid layer with effective material properties is necessary. This study focuses on flatwise tensile testing of aluminum honeycomb using different modeling approaches: discrete, continuum, and equivalent plate models. The discrete model serves as the reference due to its detailed structural representation. The continuum-Gibson model, while reasonably accurate in stress estimation, tends to overestimate displacement. Both equivalent models, Hoff and Reissner, significantly overestimate displacement, with Hoff underestimating stress and Reissner overestimating it. In contrast, equivalent models offer insights, but their accuracy varies, necessitating further calibration for precise predictions. Future research should validate these simulation results with real tests.

Abstract

Di tengah keterbatasan sumber daya, operasional Rumah Sakit Umum Daerah (RSUD) sangat bergantung pada perilaku ekstra peran atau Organizational Citizenship Behavior (OCB) tenaga medis. Penelitian ini bertujuan untuk menganalisis pengaruh Clan Culture dan Individualized Consideration terhadap OCB tenaga keperawatan, serta menguji peran Affective Commitment sebagai variabel mediasi, dengan menyoroti dinamika Clan Culture sebagai pedang bermata dua. Penelitian kuantitatif ini menggunakan desain kausalitas dengan teknik pengambilan sampel jenuh (census) yang melibatkan 115 perawat dan bidan di RSUD Kabupaten Melawi, di mana data dianalisis menggunakan Structural Equation Modeling - Partial Least Squares (SEM-PLS) dengan bantuan perangkat lunak SmartPLS 4. Hasil analisis menunjukkan bahwa Clan Culture berpengaruh positif dan menjadi prediktor paling dominan terhadap OCB, diikuti oleh Individualized Consideration, namun Affective Commitment terbukti tidak berpengaruh signifikan terhadap OCB dan gagal berperan sebagai mediator. Temuan ini menyimpulkan bahwa budaya klan efektif membangun kohesivitas tim (organizational glue) tetapi berisiko menciptakan zona nyaman yang kurang inovatif jika terlalu mendominasi, sehingga manajemen disarankan untuk mempertahankan kehangatan budaya tersebut namun mengarahkannya pada standar profesionalisme medis melalui kepemimpinan yang memberdayakan.
