Hydrodynamic Responses of Floating Oscillating Water Column for Wave Energy Conversion
No full textWave energy is a promising renewable resource due to its high-power density, predictability, and relatively low environmental impact. Oscillating Water Columns (OWCs) have been widely investigated as wave energy converters (WECs), yet floating platforms remain limited by motion responses that reduce stability and efficiency. This study examines the hydrodynamic response of a pontoon-type floater with a centered moonpool for OWC applications. Numerical simulations were performed using the Boundary Element Method (BEM) in ANSYS AQWA, focusing on the heave response amplitude operator (RAO). Case configurations included the moonpool length-to-floater length ratio (l/L) of 0.5, 0.4, and 0.3; moonpool width-to-floater beam ratio (b/B) of 0.5, 0.25, and 0.1; and drafts of 1.6, 2.4, and 3.2 m, combined through cross-variation. Validation against experimental results confirmed the reliability of the numerical approach. The results indicate that smaller floaters with higher l/L ratios and larger drafts produce higher heave RAO values, while larger floaters are less affected by the moonpool. Overall, increasing floater size enhances stability and reduces the amplifying effect of draft and moonpool variations on heave response
The Influence of Ocean Thermal Energy Conversion System Efficiency on Net Power Output
No full textIndonesia has great potential for utilizing Ocean Thermal Energy Conversion (OTEC) due to its strategic tropical conditions. This study analyzes the sensitivity of main parameters on the net power output of a 10 MW OTEC system based on the Organic Rankine Cycle (ORC) using Aspen Plus simulation. Variations on surface seawater temperature, deep seawater temperature, turbine efficiency, working fluid pump efficiency, and seawater pump efficiency were carried out. The simulation results show that turbine efficiency is the dominant factor, where an increase from 92% to 96% raised the net power from 9332 kW to 9958 kW. Seawater pump efficiency also gave a significant contribution by increasing the net power, while the working fluid pump efficiency only produced small improvement on the scale of tens of kilowatts. On the other hand, variations in warm and cold seawater temperatures had a limited effect. This happens because other parameters, such as mass flow rate of working fluid and seawater, were kept constant in the simulation, so temperature increase alone was not enough to influence system performance. These findings confirm that OTEC optimization is more effective through improving the efficiency of main components, especially the turbine and seawater pump
Model pemilihan subkontraktor menggunakan fuzzy set theory
No full textConstruction industry is an industry that involves many parties in it. The Owner of the Project, Construction Management Consultant, General Contractor, and Design and Planning Consultant are the main parties in a construction project. General Contractor as the party that undertakes the construction project always overshadowed by various things of uncertainty and risks, such as cost overruns, delay of the project, the quality of the works produced problems, claims, payment failure by the Owner, and so forth. General Contractor shall perform a variety of ways to minimize the risks. Appointment of subcontractors is an effort of the General Contractor to minimize risks although the selection process of the subcontractors fraught with risks. There is a theory that can be used in dealing with the problem of determining the right subcontractor for the project. It is called the fuzzy set theory. In general, fuzzy set theory in this thesis is used to transform the fuzzy linguistic assessment that often used by the decision makers. In this thesis, a model selection of subcontractors based on fuzzy set theory was made by using spreadsheet program. Previously, the author conducted a research to find important factors in the selection of subcontractors. The author conducted a survey on 14 (fourteen) experts from several local general contractor that located in Jakarta. Then, the author conducted a t-test to determine which factors that are considered as an important factor in the selection of subcontractors. These factors were used as an input for the model. Then, the model was tested in a real construction project. The result shows that the model needs to be modified. Once finished, the author made a couple of illustrations to test the model again. After that, the author analyzes the sensitivity of the model to find out how sensitive the model is
Successful Limb-Sparing Wide Excision of a Giant Lipofibromatosis in a 5-Year-Old Girl
No full textA 5-year-old girl presented with a big painless mass, sized 24 × 37 × 35 cm, in her lower left limb. MRI revealed a huge heterogeneous mass splaying from the left distal femur to the calcaneal region without bony erosion but compressing the arteries and causing bowing of the left tibia and fibula bones. The difficulty was to determine the best course of action taken which would either be limb salvation or amputation. Considering that only a few muscles could be saved, the author initially recommended amputation but still considered a limb-sparing procedure. After a double set-up examination in the operating room, the author ultimately decided to save the affected limb. The salvaged limb was found to be viable after the surgery, and there was no further recurrence over a subsequent 6-month follow-up period. The careful surgical decision is vital in giving the best possible care to the patient

Formulation and Characterization of Solid Tablets Using Solid Dispersion Matrix Technology: A Systematic Literature Review
No full textThe formulation of solid tablet preparations using solid dispersion matrix technology involves the selection of active ingredients, polymer matrices, fillers or enhancers, and lubricants. The active ingredient is the drug component that provides a therapeutic effect to the patient. This study aimed to conduct a systematic review study to explore the formulation and characterization of solid tablet dosage forms using solid dispersion matrix technology. The literature search process was carried out on various databases (PubMed, Web of Sciences, EMBASE, Cochrane Libraries, and Google Scholar) regarding the formulation and characterization of solid tablet preparations using solid dispersion matrix technology. This study follows the preferred reporting items for systematic reviews and meta-analysis (PRISMA) recommendations. Solid dispersion matrix technology is one of the approaches used in the formulation of pharmaceutical preparations, especially solid tablets, to achieve controlled and effective drug release. In this technology, the drug is dispersed homogeneously in a solid polymeric matrix, which acts as a binding agent. The basic principle of solid dispersion matrix technology is that the drug is delivered via gradual release from the polymer matrix
Enhanced ankle physiotherapy robot with electromyography - triggered ankle velocity control
No full textPrevious ankle physiotherapy robots, called picobot rely on predefined trajectories continuous passive movement without considering patient intent, limiting the encouragement of user-intent motion. This study then integrates electromyography (EMG) signals as triggers into picobot with an ankle velocity-based control system. The upgraded robot activates movement in specific gait phases based on muscle activity, synchronizing therapy with the patient’s intent. Functionality test on 7 young male healthy subjects investigates leg muscles, such as Tibialis Anterior, Soleus, and Gastrocnemius muscles for the most significantly contribute to ankle movements. Then, the muscle is tested to trigger picobot movements. Functionality tests revealed the Tibialis muscle significantly contributes to gait phases 2, the Soleus is prominent in phases 3 and 4, and gastrocnemius is active on phase 1. The robot successfully performs plantarflexion when EMG signals exceed a 1.58 V threshold, reaching a target position of -0.11 rad at a constant velocity of -0.62 rad/s. These findings establish a foundation for future trials since patient testing has not yet been conducted. By promoting active participation, this innovation has the potential to enhance rehabilitation outcomes. Incorporating user-intent triggers may accelerate recovery and improve healthcare accessibility in Indonesia, offering a significant advancement in physiotherapy technologies
