Abstract

Paper ini bertujuan untuk melaporkan efektivitas penggunaan kartun sebagai instrumen diagnostik miskonsepsi. Tipe soal yang digunakan dalam penelitian ini adalah soal esai yang disajikan dalam bentuk kartun dan bentuk teks. Soal dalam bentuk kartun dan teks dibagikan kepada sampel untuk dikerjakan. Setelah soal selesai dikerjakan, lembar jawaban dikumpulkan. Jawaban dari siswa kemudian dikelompokkan menjadi dua jenis jawaban yaitu : jawaban benar dan salah. Jawaban salah dibagi lagi menjadi dua yaitu : kesalahan yang acak (tidak konsisten) dan kesalahan yang konsisten. Kesalahan yang konsisten ini disebut miskonsepsi. Hasil dari masing - masing jenis jawaban ditampilkan dalam bentuk tabel. Dari tabel tersebut, masing - masing jenis jawaban dari soal bentuk kartun dan soal bentuk teks dibandingkan  Data yang diperoleh menunjukkan bahwa, ketika siswa yang sama diberi soal dalam bentuk teks dan soal dalam bentuk  kartun, soal dalam bentuk kartun dapat menghasilkan jawaban yang lebih konsisten jika dibandingkan dengan soal dalam bentuk teks.

Abstract

Kanker merupakan salah satu penyakit mematikan yang mendapatkan perhatian serius oleh peneliti dan praktisi di bidang kesehatan. Penyakit kanker adalah penyakit yang timbul akibat pertumbuhan tidak normal sel jaringan tubuh yang berubah menjadi sel kanker.Dari berbagai jenis kanker, kasus yang paling banyak terjadi pada kaum perempuan adalah kanker payudara. Teknik pengobatan kanker terus dikembangkan sehingga mampu secara selektif membunuh target sel kanker (cell targeting) dan memberikan efek yang minimal bagi sel sehat di sekitar target. Salah satu teknik pengobatan yang menjanjikan adalah Boron Neutron Captured Teraphy (BNCT). Dalam penelitian ini, sel fibroblast dan sel kanker payudara T47D dipanen pada sumuran setelah diinkubasi selama 16 jam, kemudian diberikan perlakuan  asam boron dengan dosis asam boron berjenjang 100 µM, 200 µM, 400 µM.Penembakan neutron diberikan dengan flux sebesar 1010 neutron/cm2s mengggunakan sumber neutron pada fasilitas reaktor Kartini PSTA-Batan terhadap kultur selselama 30 menit. Pada sel fibroblast tingkat kematian sel berkisar antara 2,5-21,212 % setelah pemberian asam Boron dan meningkat menjadi 24,242-71,424 % setelah penembakan neutron. Pada sel kanker payudara T47D tingkat kematian sel berkisar antara 26,761-48,76 % setelah pemberian asam Boron dan meningkat menjadi 36,585-56,25 % setelah penembakan neutron. Hasil penelitian ini menunjukkan ada pengaruh pemberian asam Boron dan penembakan Neutron terhadap tingkat kematian sel.

Abstract

Micromagnetic study of material thickness dependence of Barium-ferrite nano-dot magnetization dynamics has been performed. The used materials characteristics in this research represent the properties of Barium-ferrite. Barium-ferrite was modeled as a nano-dot with a surface area of 50 × 50 nm2 and its thickness varies from 5 nm to 100 nm. This nano-dot was simulated using micromagnetic simulator software by solving Landau-Lifshitz-Gilbert equation. According to this study, obtained that the Barium-ferrite nano-dot has excellent thermal stability. Magnetization rate of this nano-dot decreases exponentially with the increase of thickness. The fastest magnetization rate observed in 5 nm of nano-dot thickness, meanwhile 45 nm for the slowest rate. Magnetization reversal mode of this Barium-ferrite nano-dot is dominated by domain wall nucleation and propagation. During the propagation of the domain wall, the exchange interaction becomes the main aspect compared to the other contributed energies.

Abstract

Research has been conducted to find out relation position and speed to time, for objects that glide on a magnetic foundation by applying the Research and Development method. Data retrieval is done by using video train motion recordings which are analyzed using Logger Pro. The results of the analysis are represented in the form of data and graphics. Based on the data analysis and fitting using the Logger Pro, the following values are obtained: vtrain 0.027 m/s, atrain 0.034 m/s2, average train velocity 0.02572 m/s and average train acceleration 0.03662 m/s2 with RMSE (Root Mean Square Error) value of 0.013 m. The acceleration value obtained is very small and almost close to zero, so it can be said that objects that experience irregular straight motion. The graph representation of velocity over time shows an increase in speed that is not constant. This is because there is still friction between the train and the runway and friction between magnets along the track with friction forces 4,566 N. The value of kinetic energy, potential energy, and mechanical energy can be determined by using the results of Logger Pro analysis.Telah dilakukan penelitian untuk mengetahui grafik keterkaitan posisi dan kecepatan terhadap waktu, untuk benda yang meluncur di atas landasan magnetik dengan menerapkan metode Research and Development. Pengambilan data dilakukan dengan menggunakan video rekaman gerak kereta yang dianalisis menggunakan Logger Pro. Hasil analisis direpresentasikan dalam bentuk data dan grafik. Berdasarkan analisis dan fitting data menggunakan Logger Pro diperoleh nilai sebagai berikut   vkereta 0,027 m/s, akereta 0,034 m/s2, v rata-rata kereta 0,02572 m/s dan arata-rata kereta 0,03662 m/s2 dengan nilai RMSE (Root Mean Square Eror) sebesar 0,013 m. Nilai percepatan yang diperoleh sangat kecil dan hampir mendekati nol, sehingga dapat dikatakan bahwa benda mengalami gerak lurus beraturan. Representasi grafik kecepatan terhadap waktu memperlihatkan pertambahan kecepatan yang tidak konstan. Hal ini dikarenakan masih terdapat gesekan yang terjadi antara kereta dengan landasan maupun gesekan antar magnet di sepanjang lintasan dengan gaya gesek 4,566 N. Nilai energi kinetik, energi potensial, dan energi mekanik dapat ditentukan besarnya menggunakan data hasil analisis Logger Pro.

Abstract

One important factor in the hatching chicken eggs industry is hatchability of  the eggs. Conventionally, hatchability of the eggs is determined by the age of the hen. It is estimated thateggs which have high hatchability will produced from the hen which is aged between 25 to 55weeks. However, the age of the eggs hen is difficult to recognize from the egg itself, in particular ifthe identification needs to be done quickly and involving eggs in large quantities. This paperreports the identification of chicken egg from young and old hen using Near Infrared Spectroscopy(NIRS), followed by Principal Component Analysis (PCA). A total of 120 eggs with the amount of 60 eggs  that was taken from young hen (aged around 26 weeks) and the remaining 60 eggs thatwas taken from  old hen (aged arround 66 weeks) can be clearly distinguished by clusteringthrough PC1-PC2 diagram. Thus, this method can be used to identify  chicken eggs based on agehen.Keywords : Chicken Eggs, NIRS, PCA.

Abstract

Poliena adalah rantai karbon dengan ikatan rangkap dan tunggal yang saling berutan. PPP-MRD-CI mempredikasikan bahwa rantai-rantai pendek poliena memiliki struktur energi dengan tingkatan 1Ag- > 2Ag- > 1Bu+.  Waktu hidup tingkat tenaga eksitasi 2Ag- dan 1Bu+  pada poliena berada pada orde pikodetik – nanodetik tergantung pada panjang rantainya. Karotenoid sering dimodelkan sebagai rantai poliena dengan struktur energi yang sama. Paper ini membahas dinamika tingkat tenaga 2Ag- karotenoid spheroidene dalam pelarut n-hexane menggunakan spektroskopi ultra cepat pisah waktu. Didapati bahwa waktu hidup tingkat tenaga 2Ag- karotenoid spheroidene sekitar 9 pikodetik, dan sedikit bervariasi tergantung tingkat vibrasinya. Kata kunci: spheroidene, struktur energi, waktu hidup, spektroskopi

Abstract

In general, in preparing the lesson, teachers determine some components namely learning objectives, procedures, and evaluation and assessment instruments. Several problems in Physics learning on Parabolic Motion indicate possible flaws from the three components in designing the lesson. Understanding by Design (UbD) is applied as one of the alternative strategies to improve the lesson quality by considering the learning objectives, procedures, and evaluation by reversing the design, namely proposing the objectives first, evaluations as the second, and lesson steps as the last step. This is a qualitative research intended to construct an alternative design of Physics learning on Parabolic Motion using UbD. The initial Physics learning design was reviewed and analyzed by experts and revised until the final design. Understanding by Design (UbD) could be used as an alternative design construction as it helps teachers to relate the three main components, namely learning objectives, evaluations, and steps so it eased the students understand the materials comprehensively and obtain maximum score. Despite the development of current materials needs more improvement, Understanding by Design (UbD) can applied for many materials.
