Abstract

Penyakit parkinson merupakan salah satu penyakit yang mengalami gangguan neurodegeneratif. Gangguan tersebut merupakan suatu kondisi patologis sel saraf di mana sel saraf akan terus kehilangan struktur atau fungsinya. Menghadapi semakin banyaknya penderita penyakit parkinson dan jumlah ahli yang sedikit, maka diperlukan suatu metode yaitu sistem yang profesional untuk mendukung pendeteksian awal pada penyakit tersebut. Pada penelitian ini, model direpresentasikan sebagai persamaan diferensial biasa yang digabungkan sehingga dapat menggambarkan tegangan aktifitas pada neuron Subtalamic Nuckleus (STN). Penelitian ini bertujuan untuk membandingkan hasil simulasi menggunakan model dasar Hodgin-Huxley (HH) dengan penambahan arus tambahan untuk mendeteksi adanya penyakit parkinson. Perhitungan model simulasi dilakukan dengan menggunakan metode Runge-Kutta orde keempat. Hasil simulasi deteksi menunjukkan bahwa efek dari penambahan arus sinaptik dan arus stimulasi otak dalam secara signifikan terdapat tegangan respons yang berbeda dengan model asli persamaan HH pada aktifitas neuron. Hal ini disebabkan oleh reseptor terletak pada neuron glutamatergik, sehingga neuron-neuron ini akan dihambat oleh peningkatan aktivitas arus sinaptik dan stimulasi otak dalam

Abstract

This research has conducted a study of smoke distribution patterns and conditions of meteorological physical parameters based on Himawari-8 satellite imagery (Case: Forest Fires in Jambi Province). Data analysis was carried out in this study using Himawari-8 satellite image data with processed RGB False Color method in SATAID software. Meteorological factors such as hot spots, rainfall, air temperature, wind direction and speed are parameters that can affect the process of forest fires and smoke distribution. The data collected in this research is secondary data. The meteorological data and smoke images from BMKG Jakarta center, Jakarta, then the data is processed and analyzed so that it can interpret the meteorological conditions and smoke patterns in Jambi Province. The smoke images that have been collected are then processed using a laptop with SATAID Software on channels 3, 4, and 6 so that the color of the smoke and the distribution of brownish forest fire smoke can be seen in the form of images. Based on the results of the research, the state of meteorological physical parameters in Jambi Province shows a state of drought, hot spots totaling 30 locations from June 24 to 28, 2022, and low rainfall is one of the factors that trigger the process of forest fires, air temperature with an average of <25 ℃ is classified as a moderate temperature during forest fires. satellite image data and meteorological condition data in 2022, wind direction and speed below 29 kt (knots) are categorized as moderate wind gusts.

Abstract

Scientific literacy and creativity are two of several competencies that are very important to have now and in the future. However, referring to the data released by TIMSS and the results of previous research, shows that the scientific literacy and creativity of students in Indonesia are both low. This research aims to develop a STEM-Creative Problem Solving model learning tool to increase students' scientific literacy and creativity. This type of research is research & development. The development procedure in this research uses a 4D mode; define, design, develop, and disseminate. The instrument for knowing expert assessments of learning tools that have been developed uses validation sheets. From the results of the assessment of 3 (three) experts, it shows that the learning tools that have been developed have high validity with an average score for learning plans of 3.83 and an average validity score for student worksheets of 3.81. Thus, it can be concluded that the learning tools that have been developed are suitable to be continued to the limited trial stage (effectiveness test) and disseminated widely.

Abstract

This research aims to examine the relationship between cognitive style and creativity of prospective physics teachers in terms of two domains of creativity, namely personality and product. This research is quantitative and descriptive. The population of this study was 60 prospective physics teachers who were studying at Mataram University, Indonesia with a sample size of 40 people selected using the Simple Random Sampling technique. The instruments used in this research consisted of the standard Group Embedded Figures Test (GEFT) instrument, the Creative Personality test instrument, and the product creativity observation sheet. GEFT is used to identify differences in the cognitive styles of prospective physics teachers. The Creative Personality test instrument is used to determine the creativity of prospective physics teachers in terms of the aspects of fluency, flexibility, originality, and elaboration. Meanwhile, the observation sheet is used to assess the creativity of prospective teachers in producing products in the form of learning media in terms of novelty, utility, aesthetics, and authenticity. The results of the data analysis show that there is a relationship between cognitive thinking and the creativity of prospective physics teachers. Prospective physics teachers who have the FI cognitive style tend to have a better Creative Personality compared to FD (FI=1.94 > FD=1.44). However, on the contrary, the creativity of products carried out collaboratively shows that the FD group tends to get a better creative score (FI=3.01 < FD=3.41).

Abstract

Tujuan dari studi ini adalah untuk memetakan penelitian pengembangan buku ajar IPA sekolah kejuruan di seluruh dunia. Hasil dari penelitian ini diharapkan dapat memberikan informasi bagi peneliti lain dalam mengembangkan buku ajar IPA SMK di Indonesia secara khusus. Kurikulum SMK di Indonesia menempatkan IPA sebagai salah satu mata pelajaran mata pelajaran wajib yang harus ditempuh oleh siswa sebelum menempuh mata pelajaran Kompetensi Keahlian, atau dengan kata lain mata pelajaran IPA merupakan mata pelajaran penentu dalam keberhasilan menempuh mata pelajaran kejuruan siswa kedepannya. Penelitian tentang pengembangan buku ajar IPA SMK akan memberikan kontribusi terhadap perbaikan kualitas pendidikan di SMK, khusunya pada mata pelajaran IPA sebagai mata pelajaran prasyarat mata pelajaran kejuruan. Hasil penelitian menunjukkan dari 41 artikel yang dianalisis, kajian 13 artikel masih terbatas pada konten atau kurikulum IPA, 19 artikel secara spesifik menyebutkan penelitiannya tentang buku ajar IPA, hanya 9 penelitian yang secara spesifik menyebutkan sekolah kejuruan dalam penelitiaanya tentang buku ajar IPA. Namun tidak satu pun penelitian ditemukan secara khusus mengkaji tentang pengembangan buku ajar IPA sekolah kejuruan atau SMK. Berdasarkan indeksasi, ditemukan 34 artikel terindeks scopus dan 7 artikel terindeks nasional (Indonesia). tinjauan berdasarkan tahun terbit menunjukkan sebaran yang cukup merata tiap tahunnya. Kecuali pada tahun 2021 dan 2022, jumlah artikel yang ditemukan cukup banyak jika dibandingkan dengan tahun sebelumnya.
