Designing a Firefighter Motorcycle as an Effort to Provide an Early Response to Fire Disaster / Himawan Hadi Sutrisno and Triyono
No full textAs an effort to mitigate the fire disaster especially in densely populated areas with very narrow accesses, the author attempted to design a firefighter motorcycle by fulfilling the minimum equipment requirements for a firefighter motorcycle. In the process of the design, the type of the pump, the pump clutch, the pump bracket, and the dimensions of outlet and inlet pipes as well as the placement/storage of the hose and the fireproof suit in the motorcycle became the factors that were put into consideration. The motorcycle was also equipped with other firefighting equipment which would not ergonomically interfere with the motorcycle’s normal performance. This type of firefighter vehicle may be effective for such areas and suitable for an early response to the fire disaster due to its swift mobility to the fire location

No full textThe present study was conducted to find out Indonesian English as a Second/Foreign Language (L2) learners' attitudes towards cheating (AtC) in online English classes, as well as the possible influence of the combination of three variables, which are their AtC, absenteeism, and gender, on their L2 achievement as measured with their final grades. The study employed a survey method and was conducted by distributing an online questionnaire. In total, 164 Indonesian learners from various non-English departments at a university in Java participated in the study. Through descriptive statistics, it was found that generally learners reported their negative AtC in English class, suggesting disapproval towards cheating. Through multiple regression analysis, the study further found that the combination of learners’ AtC, absenteeism, and gender significantly influenced their L2 achievement, and the overall model could predict 34.5% of the total variance in L2 achievement. However, based on the beta coefficient of the three variables, only learners’ absenteeism and gender significantly affected their L2 achievement. As learners had higher absenteeism, they obtained lower L2 achievement. From a t-test analysis, female learners were found to have significantly better L2 achievement than their male counterparts. While the findings on the influence of absenteeism on L2 achievement generally conformed to literature in the field, the findings on the influence of AtC and gender on L2 achievement may suggest that further explorations may be necessary

No full textOptimation Free Space Optic (FSO) Design with Kim Model Using Space Diversity
No full textThe development of communication services in remote rural areas is difficult to use cable-based systems such as Digital Subscriber Line (DSL) and FTTx. One solution to solve this problem is to use a wireless system such as radio communication. Free Space Optic (FSO) communication system is a better choice compared to radio communication because of the flexibility of frequency usage. One of the problems of the FSO communication system is the range not too far. The range of the FSO can be increased by using the space diversity method. This study compared FSO systems that not use space diversity and FSO systems that use space diversity in three weather conditions, namely clear, haze, and fog. In taking data results using Kim model propagation with variations in the range between 100 – 2000 meters. The modulation used in this study is external modulation. The result of the analysis of FSO performance after adding space diversity, the range of FSO increases as far as 1200 meters when the condition is clear. During the haze condition, the FSO range increase as far as 800 meters. During the fog condition, the FSO range has increased as far as 300 meters. By adding space diversity, the Q-factor value has increased, and BER (Bit Error Rate) has decreased.The development of communication services in remote rural areas is difficult to use cable-based systems such as Digital Subscriber Line (DSL) and FTTx.

Correlation between implementation of health protocol and compliance among employees of Mutiara department store Slawi in the prevention of Covid-19
No full textBackground: Covid-19 pandemic has affected various aspects. One of them is the shopping center/retail sector since a shopping center is a place which is susceptible to the dissemination of SARS-CoV-2 viruses so that health protocols should be implemented and employees should comply with the health protocols in the workplace.
Objective: The study is aimed at finding the correlation between the implementation of Covid-19 health protocols and compliance among employees of Mutiara Cahaya Department Store Slawi.
Method: This is a quantitative correlative study with cross-sectional design. The research subjects were all employees of Mutiara Cahaya Department Store Slawi with the sample consisting of 48 respondents.
Data Analysis: Data were analyzed using a univariate test in the form of frequency distribution and a bivariate test using Chi-Square. The results of the analysis showed that the implementation of Covid-19 health protocols in Mutiara Cahaya Department Store Ciawi ran quite well (39.59%) with employees’ compliance which was good as well (64.58%). The results of the research showed that there was a significant correlation between the implementation of health protocols and employees’ compliance with (pValue = 0,000) meaning that if the health protocol is good then the employees’ compliance is also good.
Conclusion: Compliance with the implementation of health protocol which has been performed by the employees and management of Mutiara Cahaya Department Store Ciawi included mask wearing, hand washing, temperature check for employees and visitors, limitation of operational hours, provision of >1 meter distancing marks, installation of separators on cashier desks, and workplace cleaning with disinfectants
