Abstrak
Representasi matematis digunakan siswa ketika menghadapi soal matematika yang harus mereka selesaikan. Hal ini karena representasi matematis merupakan bentuk ungkapan ide yang ditampilkan siswa dalam bentuk yang beragam dalam situasi tertentu sebagai upaya menemukan solusi dari soal yang dihadapi. Rendahnya pemahaman siswa terhadap soal yang diberikan kemungkinan besar disebabkan oleh siswa yang tidak mampu menggunakan reprentasi matematis dengan benar. Penelitian ini merupakan penelitian deskriptif dengan pendekatan kualitatif yang bertujuan untuk mendeskripsikan representasi matematis siswa SMP, khususnya siswa berkemampuan tinggi dalam menyelesaikan soal matematika. Subjek penelitian ini merupakan salah satu siswa kelas VIII SMP 10 Nopember Sidoarjo yang dipilih berdasarkan tes kemampuan matematis. Hasil deskripsi data menunjukkan bahwa dalam menyelesaikan soal, siswa berkemampuan matematika tinggi cenderung menggunakan representasi visual untuk menyelesaikan masalah, membuat persamaan matematis atau ekspresi matematis, serta menjawab permasalahan dengan menggunakan kata-kata atau teks tertulis dengan hasil penyelesaian soal sebagian besar benar.

Abstract
Mathematical problems that they must solve. This is because mathematical representation is a form of expression of ideas displayed by students in various forms in certain situations in an effort to find solutions to the problems faced. The lack of students' understanding of the questions given is most likely due to students who are not able to use mathematical representation correctly. This research is a descriptive study with a qualitative approach that aims to describe the mathematical representation of junior high school students, especially students with high ability in solving math problems. The subject of this research is one of the eighth grade students of SMP 10 November Sidoarjo selected based on a mathematical ability test. The results of the data description show that in solving problems, students with high mathematical abilities tend to use visual representations, make mathematical equations or mathematical expressions, and answer problems by using written words or text with the results of solving problems mostly correct.

Raman scattering spectroscopy for solid-phase and metal-induced crystallization of extremely thin germanium films on glass
Authors: Kitahara Kuninori , Tsukada Shinya , Kanagawa Akari , Hara Akito 
Published: February 2021

Abstract
Raman scattering spectroscopy was applied to characterize polycrystalline germanium (Ge) on noncrystalline substrates fabricated by solid-phase crystallization and metal-induced crystallization (MIC) using copper (Cu) and tin (Sn) as the catalyzer. The subject was focused on the material for thin-film transistors in which the precursors, with the thickness of only 15 nm, were deposited by sputtering. The optical phonon mode exhibited considerable asymmetry and was separated into the following three components: crystal, low-dimensional nanosized crystallite (NC), and amorphous. The width and frequency shift of the crystal component were analyzed using the phonon confinement effect, thermal stress, and Sn composition. The transition from amorphous to the NC state was associated with the disorder in the precursor. The addition of a restrained amount of Cu led to the evident progress of crystallization and simultaneous suppression of the NC transition. The Sn composition of 3 at% was insufficient to exhibit a noticeable MIC effect.
Room-temperature bonded silicon on insulator wafers with a dense buried oxide layer formed by annealing a deposited silicon oxidation layer and surface-activated bonding
Authors: Koga Yoshihiro , Kurita Kazunari 
Published: February 2021

Abstract
We propose a fabrication process for a silicon on insulator (SOI) wafer with an extremely thick buried oxide (BOX) layer for custom micro-electro mechanical systems (MEMS) devices. A BOX layer is generally formed by thermal oxidation above 800 °C. It is limited for this method to form an extremely thick layer of more than 10 μm. Thus, we attempted to deposit the BOX layer by chemical vapor deposition at 300 °C for a short time, followed by annealing at above 300 °C to make it denser. In addition, a silicon layer was bonded to the BOX layer at room temperature by surface activated bonding not to receive thermal stress. As a result, the bonding interface had no voids. The breakdown electric field of the BOX layer in the accidental B mode was improved by annealing. Therefore, SOI wafers fabricated by our method will be beneficial to next-generation MEMS device fabrication.

Abstract
Large-scale graphene films are available, which enables the integration of graphene field-effect transistor (G-FET) arrays on chips. However, the transfer characteristics are not identical but diverse over the array. Optical microscopy is widely used to inspect G-FETs, but quantitative evaluation of the optical images is challenging as they are not classified. Here, we implemented a deep-learning-based semantic image segmentation algorithm. Through a neural network, every pixel was assigned to graphene, electrode, substrate, or contaminants, with exceeding a success rate of 80%. We also found that the drain current and transconductance correlated with the coverage of graphene films.

Plunturan is one of villages in Ponorogo, East Java Province. The prime product of Plunturan Village is a cultural heritage that is still maintained by the local village community. The various cultural products are Reyog (Reyog Anak, Reyog Perempuan dan Reyog Taruna); Gajah-Gajahan; Jathilan; Ganongan; Tledekan; Karawitan; Wayang Kulit; Coke’an; Metik Desa; Metri Desa; Metri Tandur; Campursari; and Sego Angkruk. Artists come from across generations, passed down through village elders and art groups. Artists today do not consider the potential of art in their village as their main source of income. They have other livelihoods such as farmers, traders, civil servants, government officials, teachers, health workers, private employees. This condition causes a lack of initiative from artists to attract tourists from outside the region. The role of stakeholders in Plunturan Village is very important in developing cultural tourism. The Tourism Awareness Group (Pokdarwis) which is the driving force for cultural tourism development activities must develop a strategy to make Plunturan a tourism village. Therefore, this service uses a SWOT analysis (strengths, weaknesses, opportunities and treath) to find out what strategies should be taken to initiate Plunturan Tourism Village based on local wisdom. So that culture-based development is not only aimed at improving culture, but also in carrying out development it is necessary to base on the culture that is owned, especially regarding value systems, attitudes and customs.

The problem of sexuality is a complicated problem for adolescents because adolescence is a period where
a person is faced with various challenges and problems that have an impact on adolescent psychology. The
purpose of this study was to explore the impact of risky sexual behavior on adolescents’ psychological
well-being in the Coastal Area of Rajik Village, Simpang Rimba District. The design of this study is
qualitative with a phenomenological hermeneutic approach. The number of participants in this study was
five participants consisting of three teenagers, one counseling guidance teacher, and one teenager who
became pregnant before marriage. Data collection methods in this study are in-depth interviews and field
notes. Data analysis uses hermeneutic approach1. This study received two main categories, namely: (1) risky
sexual behavior; (2) psychological impact. Adolescents who engage in risky sexual behavior are holding
hands, ever hugging, ever kissing, ever touching sensitive body parts, and having sexual intercourse in the
form of intercourse, besides the psychological effects that occur in adolescents are feeling anxious, afraid,
embarrassed and guilty and sin and consider things normal and natural to do. We encourage further research
to develop a reproductive health education module for adolescents.

Haemophilia: Its Types and Prevalence in Pakistan
Authors: Fatima Kiran , Irfan Rabeea , Azmat Laraib 
Published: February 2021

Background: Haemophilia; classified by the inefficacy of blood to clot appropriately, is a genetic bleeding disorder. As a developing country, Pakistan has limited health resources and very little awareness of hemophilia among its people.
Objectives: This research study is designed to identify the prevalence of the disease and to report the types of haemophilia common in Pakistan in order to propose suitable treatments for the prevention and cure of the disease.
Methodology: A survey questionnaire was designed and executed by the group members. Data was collected from registered Haemophilia Centers in Pakistan. Number of reported cases based on types of haemophilia, age groups, and gender were identified separately.
Results: It was evaluated that Pakistan continues to have a growing number of hemophilia cases at an alarming rate. The research study also showed how there is a lack of affordable and proper health care in the country, due to which several cases go unreported and untreated.
Conclusion: For the containment of this bleeding disorder, time for taking proper action is passing. Proper health care systems should be set up which are accessible to the majority of the population. Awareness programs should be designed and people should be encouraged for regular laboratory tests to prevent late diagnosis.
Gaussian Process Modeling Fermi-LAT γ-Ray Blazar Variability: A Sample of Blazars with γ-Ray Quasi-periodicities
Authors: Yang Shenbang , Yan Dahai , Zhang Pengfei , Dai Benzhong , Zhang Li 
Published: February 2021

Abstract
Blazar variability may be driven by stochastic processes. On the other hand, quasi-periodic oscillation (QPO) behaviors were recently reported to be detected in the Fermi-LAT data of blazars. However, the significances of these QPO signals given by traditional Fourier-like methods are still questioned. We analyze γ-ray light curves of the QPO blazars with two Gaussian process methods, CARMA and celerite, to examine the appropriateness of Gaussian processes for characterizing γ-ray light curves of blazars and the existence of the reported QPOs. We collect a sample of 27 blazars with possible γ-ray periodicity and generate their ∼11 yr Fermi-LAT light curves. We apply the Gaussian process models to the γ-ray light curves, and build their intrinsic power spectral densities (PSDs). The results show that in general the γ-ray light curves can be characterized by CARMA and celerite models, indicating that γ-ray variabilities of blazars are essentially Gaussian processes. The resulting PSDs are generally the red noise shapes with slopes between −0.6 and −1.7. Possible evidence for the γ-ray QPOs in PKS 0537−441 and PG 1553+113 are found in the Gaussian process modelings.

Abstract
We present the discovery of a low-redshift damped Lyα (DLA) system in the spectrum of background starburst galaxy SDSS J111323.88+293039.3 (z = 0.17514). The DLA is at an impact parameter of ρ = 36 kpc from the star-forming galaxy, SDSS J111324.08+293051.2 (z = 0.17077). We measure an H i column density of N(H i) = 3.47 × 1020 cm−2 along with multiple low-ionization species such as N i, N ii, Si ii, C ii, and Si iii. We also make an estimate of the covering fraction to be 0.883, giving us a limiting size of the DLA to be A
DLA ≥ 3.3 kpc2. Assuming a uniform column density over the entire DLA system, we estimate its mass to be M
DLA ≥ 5.3 × 106
M
⊙. The extended illuminator and the low redshift of this DLA give us the unique opportunity to characterize its nature and the connection to its host galaxy. We measure a velocity offset of +131 km s−1 from the systemic velocity of the host for the DLA. This velocity is −84 km s−1 from the projected rotation velocity of the host galaxy as measured using a newly constructed rotation curve. Based on the size of the host galaxy, the H i column density, and the gas kinematics, we believe this DLA is tracing the warm neutral gas in the H i disk of the foreground galaxy. Our detection adds to a small set of low-redshift DLAs that have confirmed host galaxies, and is the first to be found using an extended background source.
