Research objectives This is analyze the effect of problem-based learning and gender on students' curiosity, problem understanding, and problem-solving abilities. This research was conducted on two classes of Mataram Model X Madrasah Aliyah students who were selected using cluster random sampling technique. Student curiosity data was measured using a questionnaire instrument, while problem understanding and students' problem solving abilities were measured using a question test instrument. Then, the data were analyzed by MANOVA at a significance level of 5%. The results showed that problem-based learning had a significant effect on curiosity and problem solving abilities, but did not have a significant effect on problem understanding. . The curiosity of male students is higher than that of female students, but the opposite occurs in the conventional group in classes taught with problem-based learning. The problem comprehension of male students was lower than that of female students in both study groups. problem solving of female students is higher than the group of male students. However, gender has no significant effect on curiousity, problem comprehension , and problem solving ability. The interaction of problem-based learning and gender has no significant effect on curiousity problem comprehension and problem solving abilities.
研究目的分析基于问题的学习和性别对学生好奇心、问题理解和解决问题能力的影响。本研究采用整群随机抽样技术对两个班的Mataram Model X Madrasah Aliyah学生进行了研究。学生的好奇心数据是使用问卷工具测量的，而问题理解和学生的问题解决能力是使用问题测试工具测量的。然后，通过MANOVA以5%的显著性水平对数据进行分析。结果表明，基于问题的学习对好奇心和问题解决能力有显著影响，但对问题理解没有显著影响。男生的好奇心高于女生，但在以问题为基础的学习中，传统群体的好奇心则相反。两组男生的问题理解能力均低于女生。女生的问题解决能力高于男生。然而，性别对好奇心、问题理解和问题解决能力没有显著影响。基于问题的学习与性别的互动对安全感、问题理解和问题解决能力没有显著影响。

Tourism is one of the economic sectors that is developing relatively rapidly and has the potential to become a source of foreign exchange due to an increase in the number of tourists. Caldera Toba Geopark is one of the UNESCO-owned Geoparks in Indonesia as a tourist destination that depends on natural potential to be vulnerable to climate change. The relationship between climate and tourism from the comfort index is needed in determining tourist comfort. Climate parameters that become the calculation of the climate comfort index such as air temperature, rainfall, wind speed, length of sunshine and cloud cover are part of the thermal, physical and aesthetic aspects of climate comfort weighting. Climate projection data in this study is the RCP 4.5 scenario with the ACCESS 1-3 model. Using the TCI and HCI methods, the results of the temporal pattern analysis on the climate comfort index for the period 2031-2050 have a 'Bimodal - Shoulder Peak' distribution pattern. Based on the results of the spatial pattern analysis, the level of tourist climate comfort for the period 2031-2050 both with TCI and HCI methods is dominated by the comfortable category index where the peak comfort occurs in December with a very comfortable category. The lowest comfort level with the TCI method occurs in June in the comfortable category, while the HCI method in July with a comfortable category. In the end, the results of this study provide recommendations for the best tourist time in the Caldera Toba Geopark from September to December. The recommended geosite locations are Simanindo - Batu Hoda and Hutatinggi - Sidihoni geosites.

Belawan port and coastal areas were also not spared from the impact of the tidal flood. This study aims to determine the performance of the Delft3D hydrodynamic model in simulating sea level and waves in tidal floods at Belawan port and coastal area. Final operational global analysis data, MSLP data from NOAA/NCEP, and tidal data from ECMWF were used to run the Delft3D model. The model output was verified by using tide gauge observation data from BIG (Geospatial Information Agency). This research resulted in a mapping of areas affected by tidal flooding in the Belawan port and coastal area by analyzing the interaction between atmosphere, consisting of wind speed and direction parameters and sea parameters in the form of significant wave height. Based on the results of the Delft3D verification with observation data, the average error value is 23.5 cm and the coefficient of correlation is 0.93. This shows that the Delft3D model is quite good at simulating tidal flood heights in the Belawan port and coastal area. Based on atmospheric analysis, it does not really affect the increasing wave height. The influence is given by significant sea wave height, which can increase the height of tidal floods.

The results of this study are 8 hypotheses, most of which have significant value, including H1: the perception of using HIMS as an opportunity (PO) will positively influence the adoption of a benefit-maximizing strategy (BM) of significant value (sig.0.007). H2: the perception of using HIMS as an opportunity (PO) will positively influence the adoption of a benefit satisfaction strategy (BS) with significant value (sig. 0.00). H3: The manager's perception of the use of HIMS as a threat (PT) will positively influence the disturbance management strategy (DH), with a significant value (sig. 0.000). H5: when managers perceive a situation as an opportunity, the more control they feel over the benefits of HIMS, the more likely they are to adopt a benefit maximizing (BM) strategy of significant value (sig. 0.000). H6: When managers perceive a situation as an opportunity, the more control they feel over the benefits of HIMS, the more likely they are to adopt a significant value benefit satisfaction (BS) strategy (sig. 0.016). H7: when a manager perceives the use of HIMS as a threat, the greater the perceived control over the implementation of security measures, the more he or she will adopt an intrusion management strategy (SP) of significant value (sig. 0.004). It was concluded that in using HIMS to optimize its use from the perspective of threats and opportunities, managers can adopt benefit maximizing strategies, benefit satisficing strategies, and disturbance handling strategies.

The Regional Meteorology, Climatology, and Geophysics Agency (BMKG) plays a crucial role in providing accurate and reliable services related to meteorology, climatology, and geophysics. Temperature observation is one of the important tasks carried out by the BMKG as it is essential for weather and climate forecasting, as well as for predicting natural disasters. To ensure the accuracy of the data, the thermometers used for temperature observation must be in good working condition and calibrated regularly. According to the Republic of Indonesia Law No. 31, Article 48, Year 2009 on Meteorology, Climatology, and Geophysics (MKG), all observation equipment must be in good working condition and calibrated regularly. Calibration is a crucial step in ensuring the accuracy and operational fitness of the observation equipment. The International Organization for Standardization (ISO) / International Electrotechnical Commission (IEC) 17025:2017 also emphasizes the importance of ensuring the quality and accuracy of all measurement instruments. The Calibration Laboratory at the BMKG Regional Office I in Medan is accredited with ISO/IEC 17025:2017 by the National Accreditation Committee (KAN). However, the calibration process can be time-consuming and requires constant monitoring to achieve stable data. During temperature and humidity calibration, the calibration laboratory's environment must be conditioned to maintain the performance of sensitive instruments that are susceptible to environmental changes. This study aims to design an automated temperature calibration monitoring system using the Internet of Things (IoT) to improve the efficiency of the calibration process and achieve maximum calibration results at the BMKG Regional Office I in Medan. The system will enable the calibration personnel to monitor the calibration process remotely and receive real-time data, allowing for more effective analysis and decision-making.

The Observation type rain gauge is a manual type rain gauge that requires a measuring cup to measure rainfall in millimeters (mm) of rain. Precise measurement requires calibration of the measuring cup so that the scale reading on the measuring cup can be trusted. Calibration of measuring cups using the mass method related to volume can use an analytical balance. Technological developments can make manual analytical balance calibration automatic by utilizing microcontrollers and pumps in filling the volume. The design of the analytical balance gets results where the average correction value for the 50 ml set point is 0.001ml, the 100 ml set point is -0.760 ml, the 150 ml set point is -0.024 ml, the 200 ml set point is -0.739 ml, and the 250 ml set point is 0.628 ml. The uncertainty value for all set points is ±0.58 ml. The correction value at each set point is different, this is influenced by the value of the measuring cup meniscus, water temperature, and Load Cell sensor. The data generated by the tool can be downloaded through the Arduino IDE application and produced files in Excel.

Anxiety is an emotional response to an assessment that describes a state of worry, anxiety, fear, and unrest accompanied by various physical complaints. During the treatment process, anxiety is not only felt by a patient but can also be experienced by the patient's family. The patient's family is one of the full decision-holders when the patient is in an emergency or critical condition and must be given immediate treatment. The research objective was to determine the relationship between the level of emergency (triage) and the anxiety level of the patient's family. The research design used was a cross-sectional analysis, the study was carried out on 30 May-13 June 2018 at the Emergency Room of RSUD Dr. Iskak Tulungagung. The sample in this study was the patient's family using a consecutive sampling technique, a sample of 30 respondents was obtained. Data was collected using the HARS questionnaire. Data were processed by editing, coding, scoring, tabulating, and analyzing with Spearman's rho statistical test. The results of the Spearman's rho statistical test, obtained a value of p = 0.000 to test the relationship between the level of emergency (triage) and the anxiety level of the patient's family. With a significant level value of = 0.05, which means there is a relationship between the level of emergency (triage) and the anxiety level of the patient's family. The conclusion from this study is that the higher the level of emergency (triage) of the patient, the more anxiety of the patient's family will affect. Recommendations for hospitals, especially in the Emergency Room, are expected to further improve communication between health workers and patient families. To reduce the possibility of anxiety by the family.Relationship between Emergency Level (Triage) and Anxiety Level of the Patient's Family.

Extreme rain is an event that has an impact on various sectors of life. Therefore, this study aims to determine the spatial and temporal characteristics of extreme rain events in North Sumatra Province in the time period between 1991-2020. In accordance with the WMO recommended rain index, the frequency and intensity of rain were calculated using 50 rain stations spread across North Sumatra where the data had passed the quality control test for empty data. Spatial patterns were analyzed by mapping the climatological mean of the indices then for trend patterns were tested using the Mann-Kendal non-parametric test. The results showed that extreme rainfall events with low frequency and intensity occurred on the east coast while high frequency and intensity occurred in mountainous areas. Based on the temporal trend test, it shows that in general an insignificant trend dominates in this area. Significant and consistently increasing trends are only found at several points, namely in the districts of Deli Serdang (5 station), Batu Bara (1 station), Humbang Hasundutan (1 station), Langkat (2 station), Labuhan Batu Utara (1 station), Medan (1 station), Pematang Siantar (1 station) and Serdang Bedagai (1 station). Meanwhile, a significant and consistently decreasing trend was found in Asahan Regency (1 station), Simalungun (2 station), North Tapanuli (1 station), and North Labuhan Batu (1 station).
