Judul: Hubungan Empati dan Kecerdasan pada Mahasiswa  Sarjana di Indonesia
Abstrak: Empathy is the ability to understand the feelings and emotions of others, which is important for social interaction in humans. Empathy was predicted can be influenced by the intelligence because individuals with high intelligence are better at understanding and interpreting situational cues. So far, few studies have directly explained the correlation between empathy and intelligence in undergraduate students, but the results are inconsistent and imply that some demographic and cultural backgrounds affect the results. In addition, the relationship between empathy and intelligence of undergraduate students in Indonesia has not been known yet. Therefore, this study aimed to determine the relationship between empathy and intelligence of undergraduate students in Indonesia. This research was conducted using an online platform, with a total of 316 undergraduate students who participated in this research. Each respondent filled out a questionnaire consisting of demographic data, the Interpersonal Reactivity Index (IRI) to assess self-report empathy, and their intelligence using the Baddeley Reasoning Test (BRT). This study showed that undergraduate students in Indonesia have high self-report empathy (Mean = 74.09) and intelligence scores (Mean = 20.58). However, the correlation between empathy and intelligence has no significant correlation (R = –0.017, p-value = 0.76). Thus, it implies that intelligence is not the variable that affects empathy., Empati adalah kemampuan untuk memahami perasaan dan emosi orang lain, yang penting untuk interaksi sosial pada manusia. Empati diprediksi dapat dipengaruhi oleh kecerdasan karena individu dengan kecerdasan tinggi lebih baik dalam memahami dan menginterpretasikan isyarat situasional. Sejauh ini, beberapa penelitian menjelaskan korelasi antara empati dan kecerdasan pada mahasiswa sarjana, tetapi hasilnya tidak konsisten dan menunjukkan bahwa beberapa latar belakang demografi dan budaya mempengaruhi hasil penelitian. Selain itu, hubungan empati dengan kecerdasan mahasiswa sarjana di Indonesia belum diketahui. Oleh karena itu, penelitian ini bertujuan untuk mengetahui hubungan empati dengan kecerdasan mahasiswa sarjana di Indonesia. Penelitian ini dilakukan dengan menggunakan platform online, dengan jumlah mahasiswa sarjana sebanyak 316 orang. Setiap responden mengisi kuesioner yang terdiri dari data demografi, Interpersonal Reactivity Index (IRI) untuk menilai empati laporan diri, dan kecerdasan mereka menggunakan Baddeley Reasoning Test (BRT). Penelitian ini menunjukkan bahwa mahasiswa sarjana di Indonesia memiliki skor tinggi pada empati yang dilaporkan diri sendiri (Mean = 74.09) dan skor kecerdasan (Mean = 20.58). Namun korelasi antara empati dan kecerdasan tidak memiliki korelasi yang signifikan (R = –0,017, p-value = 0.76). Dengan demikian, menyiratkan bahwa kecerdasan bukanlah variabel yang mempengaruhi empati.

Abstrak: Empathy is the capacity to understand the emotions and feelings of others, which is essential for social interaction in human life. In general, empathy can be classified into cognitive empathy and emotional empathy. Cognitive empathy is based on perspective-taking and fantasy scales, while emotional empathy is based on personal distress and empathic concern scales. Recent research highlights that psychological factors predicted can contribute to variations in empathy, such as fluid intelligence and self-control. There has not been much research exploring for a direct relationship between empathy, fluid intelligence, and self-control, and several previous studies obtained results that were inconsistent with one another, so we would like to investigate it. A total of 1084 Indonesians participated in an online study by completing a questionnaire that included demographic questions, the Interpersonal Reactivity Index (IRI) questionnaire to measure empathy, the SelfControl Scale (SCS) questionnaire to assess self-control, and the Baddeley Reasoning Test (BRT) to determine fluid intelligence. We found on each of the cognitive empathy scales correlation with fluid intelligence and self-control showed that individuals with high perspective-taking tend to have high fluid intelligence and high self-control. Then, individuals who have high fantasy tend to have high fluid intelligence and low self-control. Moreover, on each of the emotional empathy scales correlation with fluid intelligence and self-control, showed that individuals with high personal distress tend to have low fluid intelligence and low self-control. Furthermore, individuals with high empathic concern tend to have low fluid intelligence and high self-control. Our study found the correlation pattern consistent with previous studies indicating that fluid intelligence and self-control are important psychological factors that can be correlated to empathy., Empati merupakan kapasitas untuk memahami emosi dan perasaan orang lain, yang sangat penting untuk interaksi sosial dalam kehidupan manusia. Secara umum, empati dapat diklasifikasikan menjadi empati kognitif dan empati emosional. Empati kognitif dapat didasari oleh skala pengambilan perspektif dan fantasi, sedangkan empati emosional dapat didasari oleh skala kesusahan pribadi Empati merupakan kapasitas untuk memahami emosi dan perasaan orang lain, yang sangat penting untuk interaksi sosial dalam kehidupan manusia. Secara umum, empati dapat diklasifikasikan menjadi empati kognitif dan empati emosional. Empati kognitif dapat didasari oleh skala pengambilan perspektif dan fantasi, sedangkan empati emosional dapat didasari oleh skala kesusahan pribadi dan kepedulian empati. Penelitian terbaru menyoroti faktor-faktor psikologis yang diperkirakan dapat berkontribusi pada variasi empati, seperti kecerdasan cair dan pengendalian diri. Belum banyak penelitian yang mencari hubungan langsung antara empati, kecerdasan emosi, dan pengendalian diri, dan beberapa penelitian sebelumnya mendapatkan hasil yang tidak konsisten satu sama lain, sehingga kami ingin menyelidikinya. Sebanyak 1084 orang Indonesia berpartisipasi dalam penelitian daring dengan mengisi kuesioner yang mencakup pertanyaan demografis, kuesioner Interpersonal Reactivity Index (IRI) untuk mengukur empati, kuesioner Self-Control Scale (SCS) untuk menilai pengendalian diri, dan Baddeley Reasoning Test (BRT) untuk menentukan kecerdasan cair. Kami menemukan pada masingmasing skala empati kognitif berkorelasi dengan kecerdasan cair dan pengendalian diri menunjukkan bahwa individu dengan pengambilan perspektif yang tinggi cenderung memiliki kecerdasan cair yang tinggi dan pengendalian diri yang tinggi. Kemudian, individu yang memiliki fantasi yang tinggi cenderung memiliki kecerdasan cair yang tinggi dan pengendalian diri yang rendah. Selain itu,

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
