Get PDFPicohydro is a power plant that produces 5 kW of power which consists of 3 components, namely air flow, turbine, and generator to convert maximum energy into electrical energy. Picohydro is an alternative power plant as a substitute for fossil fuel power plants (diesel and gasoline). The PCRlake flow has a flow of 0.019 m3/s which can be used as a potential source of energy to generate electricity, where the tools used are screw turbines, V-belt transmission, and DC generators. The results of the design of the screw turbine that are made have a turbine length specification of 1,140.5 mm, an outside diameter of 419.4 mm, an inside diameter of 225 mm, a turbine pitch of 503.2 mm, a number of blade turns 2 pieces, a turbine angle of 26o, a thread angle of 21o, and a head of 0.5 m. For the transmission, there are 2 type A -V belts that connect the turbine rotation to the DC generator rotation. The results obtained that the theoretical power available in the PCR lake flow is 95.01 watts. The average rotation produced by the 1,398 rpm generator is able to stably turn on as many as 6 DC lamps with a total load of 60 watts. By testing the DC lamp load, a total load of 60 watts produces a generator power of 29.14 watts, a screw turbine power of 34.08 watts. By testing using a braking system at turbine rotation it produces a maximum torque of 13.12 Nm with a screw turbine power of 46.70 watts and a turbine mechanical efficiency of 49.16%

Pengembangan Sistem Pendingin Cold Box Penyimpanan Ikan Dengan Pemanfaatan Pcm
Get PDFOne of the technologies in the refrigeration system to improve power and cost efficiency is to utilize technology to overcome this problem is to use phase change materials (PCM) to replace standard refrigerants. The purpose of this study is an attempt to reduce the operational cost of fish storage with a cold box cooling system for fish storage by utilizing PCM. The method used in this research is the experimental method. From the results of the study obtained data using a variation of 2 PCM compressor takes 219.7 minutes when mode ON for 7 hours of testing, variation 4 PCM compressor takes 202.7 minutes when mode ON for 7 hours of testing, variation 6 PCM takes 177.4 minutes when mode ON for 7 hours of testing. With this variation 6 PCMs are more optimal in helping to reduce compressor working time. The more the number of PCMs placed in the cold box can help reduce the compressor on/off cycle and the electrical energy required by the compressor is more efficient, the most efficient variation is the 6 PCM variation with a power efficiency of 15.31%. With the use of PCM can save operational costs up to 59.54% compared to using ice blocks. The design of cold boxes using PCM will benefit after 3 months of use compared to using block ice
The Analysis of Loosening of Bolt Connection Due to Structural Vibration Through Changes in Dynamic Characteristics
No full textBolted joints are generally used to connect two or more mechanical structures due to their ease of assembly and disassembly for maintenance. However, the problem of vibration is one of the main challenges when the tightness of the bolted joints is insufficient, causing failures such as looseness and resulting in disconnection. Looseness is the most common cause of dynamically loaded bolted joint structure failure. This study tested a simple bolt joint structure to observe the looseness indication of the bolt joint after it was vibrated using a shaker in a single-frequency excitation. A freely fixed beam consisting of two beams connected by a bolt and subjected to varying bolt tightening torques. Then the response measurement is carried out by recording the FRF graph obtained from loosening and tightening bolt torque effects. Modal parameters such as personal frequency and damping ratio were collected through experimental modal analysis (EMA). It was found that the structure’s vibration could change the conditions of loosening or lower tightening torque indicated by shifting the structure’s natural frequency. In addition, the damping characteristics are also affected by changes in the tightening torque. Especially when conditions are loose, the damping ratio becomes much higher than that of tightening
Social Commerce Investigation: The Role of Satisfaction and Loyalty on Repurchase Intention
Get PDFThis study aims to find evidence of the effect of satisfaction and loyalty on repurchase intentions in social commerce through social exchange theory. This research focuses on five variables: reputation, information quality, satisfaction, loyalty, and repurchase intention. This research is motivated by satisfaction, which is not optimal in shaping repurchase intentions. Loyalty is an aspect of novelty in this research. The research method used is a quantitative approach. Data collection techniques support this research through online questionnaires. The data used in this study are primary as many as 219 respondents. Data processing analysis uses the Structural Equation Modeling (SEM) method and is supported by SPSS 25 and IBM AMOS 22 software. This study's results indicate that satisfaction significantly affects loyalty and repurchase intentions in social commerce. The results also found that loyalty has no significant effect on repurchase intentions. Satisfaction is an important factor for a user to have the intention to repurchase in the same place. A good reputation and quality information social commerce provides influence this.
 
Analisis dan Perkuatan Kolom Baja Struktural Akibat Beban Gempa Menggunakan HBeam
Get PDFEvaluation or study of existing building structures must consider the strength and stiffness of structural components due to gravity loads and earthquake loads. The strengthening to the existing Hbeam column structure is to add steel plates to the existing Hbeam column. This method is a way to improve structural performance due to earthquake loads in terms of ease of implementation, time and cost when compared to replacing or adding new structural components. The purpose of this study was to analyze the strengthening of Hbeam column steel plate due to seismic loads. Parameters analyzed were vibration period, lateral displacement and internal forces due to earthquake loads. This research is a quantitative analytical research, where the geometry data of the 3D frame portal structure is determined independently, while the material and loading data are based on (SNI 1727:2013) and (SNI 1729:2019). The 3D frame portal is modeled and analyzed using finite element based software, ETABS software. The results of the analysis show that the strengthening of the Hbeam column by adding a steel plate to the existing Hbeam column which is installed horizontally in the middle of the cross section with dimensions of 15 mm thick and 145 mm long (18.59% of the cross-sectional area of the Hbeam column) increases the stiffness of the structure by 12.01% and 14.2% respectively - for vibration period and lateral drift, respectively. The lateral displacement is smaller than the allowable lateral displacement with a drift ratio of less than 130%, so the structure does not experience a soft story. The average maximum internal forces (moment, shear and axial force) due to the earthquake load of the column structure with reinforcement increased by 12.50%, 9.68% and 14.01% respectively compared to the structure without strengthening along with the addition of dimensions to the existing Hbeam column
Strategic Business Decision-Making On Talent Management Scenarios To Support The Vision Of Growing Into A Large-Scale Company (Case Study Of G Communications Agency)
No full textIn the communications consultation or agency, people or talents are the bread and butter of the company since they play crucial roles in setting up the collaboration scheme, quality of service, and the company’s culture. Therefore, talent management becomes significantly crucial for the company to strive. G Communications agency is a local agency in Jakarta that has a vision to be a large-scale company but is facing difficulties particularly in its talent management since most of its talents are in contract-based employment. This study aims to help the company determine the best hiring scheme from the three alternatives derived from cost and benefit analysis and later being calculated using SMART method. The result shows that alternative 1 with highest cost and value, and alternative 3 with lowest cost and value were performing below the trend line. Meanwhile, alternative 2 as the intermediate choice was performing above the trend line. The sensitive analysis also shows that despite changes in the weight for each group, the ranking of each alternative remains unchanged. Therefore, can be concluded that the alternatives are not sensitive nor easily perturbed by the change of the aggregate of the weighted value
