PERAN SELF CONTROL TERHADAP PERILAKU AGGRESSIVE DRIVING PENGGUNA SEPEDA MOTOR

The aim of the study is determining whether there is a role of self control toward aggressive driving behavior on motorcyclist. This study hypothesizes that there is a role of self control toward aggressive driving behavior on motorcyclist. This study used 200 young male motorcyclists in South Sumatera as participants who already has driving license C and used 50 motorcyclists as the trial participants. The sampling technique was purposive sampling. The study measurements are self control scale and aggressive driving behavior scale that refer to Averill’s (1973) self control types and Tasca’s (2000) aggressive driving behavior forms. Data analysis used simple regression.The result of simple regression shows R square = 0,507, F= 203,680, and p = 0,000 (p<0,05). This means that self control has a significant role toward aggressive driving behavior. Thus, the hypothesis could be accepted and self control contribution toward aggressive driving behavior is 50,7%

MEMAHAMI RASA INGIN TAHU REMAJA DITINJAU BERDASARKAN JENIS KELAMIN

Abstrak  Rasa ingin tahu diprediksi membantu remaja terus belajar dan tumbuh kembang didalam kehidupan. Rasa ingin tahu dapat digambarkan melalui sikap antusias remaja dengan mengamati, mendengar, mencari, dan menggali informasi untuk memperoleh kepastian akan kebenaran. Keingintahuan mengakibatkan remaja mendapatkan informasi baru yang memungkin remaja memiliki keyakinan dan termotivasi untuk mengeksplorasi lebih jauh perihal keingintahuannya. Tujuan penelitian ini adalah untuk mengetahui perbedaan rasa ingin tahu remaja ditinjau berdasarkan jenis kelamin. Metode yang digunakan adalah pendekatan kuantitatif komparatif dengan menggunakan uji beda dengan penentuan sampel yang digunakan pada penelitian ini harus disesuaikan dengan tujuan peneliti yakni termasuk dalam kategori remaja akhir dengan jumlah partisipan sebanyak 50 remaja laki-laki dan 50 remaja perempuan. Pengumpulan data dalam penelitian ini adalah menggunakan Curiosity and Exploration Inventory yang diadaptasi oleh Kashdan, Rose & Finchan (2004) dengan model skala Likert yang dianalisa menggunakan uji hipotesis independent sample t-test. Hasil penelitian menunjukkan bahwa nilai t 2,088 dan uji signifikansi menunjukkan 0,004 < 0,05 artinya ada perbedaan rasa ingin tahu yang signifikan antara remaja laki-laki dan perempuan. __________________________________________________________ Abstract Curiosity is predicted, helping teenagers continue to learn and grow in life. Curiosity can be illustrated through the enthusiasm of teenagers by observing, listening, searching, and digging for information to obtain certainty about the truth. Curiosity causes teenagers to get new information that allows them to have confidence and be motivated to explore further about their curiosity. The purpose of this study was to determine differences in curiosity of teenagers by gender. The method used is a comparative quantitative approach using a different test with the determination of the sample used in this study must be adjusted to the objectives of the researcher that is included in the category of late teenagers with the number of participants is 50 boys and 50 girls. The data collection in this study was using the Curiosity and Exploration Inventory which was adapted by Kashdan, Rose & Finchan (2004) with a Likert scale model analyzed using hypothesis testing independent sample t-test. The results showed that the value of t was 2.088 and the significance test showed 0.004 <0.05, meaning there is a significant difference in curiosity between boys and girls

STRATEGI PENGEMBANGAN INDUSTRI KREATIF UNTUK INOVASI

Changes are very fast and full of uncertainty, such as the current condition of COVID-19, which makes it very difficult for supply chain managers even though they already have a very good regularity. Changes in consumer preferences are very fast and even difficult to predict. The purpose of research and development was to identify the factors that influence the performance and competitiveness of the creative industry for innovation. It needed to be informed that the development strategy was not only providing information, availability of goods, money, and innovation, but there were pluses in terms of developing knowledge, knowing the strength map, implementing efficiency accompanied by value. Analysis of Strengths, Weaknesses, Opportunities, and Threats (SWOT) was used in determining alternative strategies, while the analysis focus strategy used the Quantitative Strategic Planning Matrix (QSPM) method by considering the Total Attractiveness Scores obtained. For this reason, the potential and challenges in a series of processes (transformation activities and transaction activities) of a product must be carefully scrutinized, so that added value can be created at each stage. The results of the SWOT analysis resulted in five alternative strategies, which were then followed by a QSPM analysis to obtain the total attractiveness scores. The results of the analysis gave the highest total value on the importance of potential resource availability with a value of 15.862 followed by the second to fifth order, the need to understand rapid market changes (14.840), build partnerships (14.646), standardized and sustainable products (14.123) and develop efficiency principles for competitiveness (12.288), respectively. Recommendations are given that resource potential and rapid response to market demands in addition to the other three factors should be considered in the development strategy for innovation in creative industries.

LNA Prototype at 54 MHz to 88 MHz Using Discrete Components

This paper presents a design and prototyping of a Low-Noise Amplifier (LNA) for Wireless Regional Area Network (WRAN) operating in TV broadcast bands between 54 MHz – 88 MHz. The LNA design was then implemented by using discrete components. Components values was obtained by utilized DC analysis according to specifications which follows the Institute of Electrical and Electronics Engineering (IEEE) 802.22 standard on WRAN technical specifications. Simulation with 88 MHz produced S11 = -5.72 dB, S12 = -41.57 dB, S21 = 15.07 dB, S22 = -4.76 dB, Noise Figure (NF) = 3.9 dB, Input Third Order Intercept Point (IIP3) = 2.21 dBm, and power consumption of 45.39 mW. Experiments results on 88 MHz showed S11 = -6.13 dB and S21 = 0.74 dB

A 5.9 GHz Low Power and Wide Tuning Range CMOS Current-controlled Ring Oscillator

Designing low power, low noise, wide tuning range and small size circuit in one single chip is very challenging. This paper describe a low power, wide tuning range three-stage current-controlled ring oscillator (CCO) designed on 0.18um CMOS technology. The CCO circuit has tuning range from 251 MHz to 5.5 GHz or 183% wide. It consumes only 144 uA to 9.76mA by using 1.8V power supply. Phase noise is -104 dBc /Hz at 5.5 GHz and 4 Mhz offset frequency.  Calculated FoM is -154.4 dBc /Hz which is the best among published counterpart papers. The size of the core oscillator circuits without bonding pads is only 0.0003 mm2.DOI:http://dx.doi.org/10.11591/ijece.v2i3.22
