Siti Maryam Ahamy, Hadi Nasbey, Upik Rahma Fitri
Universitas Negeri Jakarta
Abstract
This study aims to design a heat transfer experiment set based on an Arduino microcontroller Arduino with a data logger this research uses Research and Development method, with 4D research model (Define, Design, Develop, and Disseminate) which is limited to the Design stage initial research data collection at the Define stage was carried out giving questionnaires to student, interviewing teacher, observing school laboratories and literature study review by observing school laboratories. The data obtained is analysed and use as a guide to determine material concept, learning objectives, and learning activities. Based on data analysis, an experiment set of heat transfer that can record data continuously is needed. At the Design stage, researchers choose the format and type of learning media, arrange test outline, and design experiment set that can accommodate learning needs. The result is a design for a heat transfer experiment set based on an Arduino microcontroller with a data logger as a solution to the learning needs found in the Define stage. The experiment set design consists of a physical experiment tool and a computer application.

Abstract
This study aims to design a technology-based rolling motion experiment tool. The research employs the research and development method, with ADDIE research model (Analyze, Design, Develop, Implement, and Evaluate) which is limited to the Develop stage on focus to design research product. In the Analyze stage, researchers validate performance gaps by interviewing teachers, establish learning objectives, identify the resources required, and estimate the associated costs. Based on the validation of the performance gap, it was concluded that a technology-based rolling motion experiment tool was needed. In the Design stage, the researcher creates an inventory of tasks and performance objectives, and creates a testing strategy. In the Develop stage, researchers prepare learning plans and design learning materials (research products). Researchers conduct evaluations at the end of each stages. The result obtained were a design of rolling motion experiment tool based on technology as a solution of performance gaps.

Analisis Perbedaan Unsur Dalam Bayam Hijau (Amaranthus Viridis) Antara Metode Budidaya Konvensional Dan Hidroponik Dengan Menggunakan Metode Laser Induced Breakdown Spectroscopy (Libs)
Artha Paulina Simamora, Mangasi Alion Marpaung
Universitas Negeri Jakarta
Abstract
Penelitian ini bertujuan untuk menganalisis kandungan unsur dalam sayuran bayam yang dibudidayakan menggunakan metode konvensional dan hidroponik menggunakan metode Laser-Induced Breakdown Spectroscopy (LIBS). Penelitian ini melibatkan pengambilan sampel daun bayam yang ditanam dengan kedua metode budidaya tersebut. Sampel-sampel tersebut kemudian diproses dan dianalisis menggunakan metode LIBS. Dalam pengukuran LIBS instrumen yang sesuai digunakan untuk mengidentifikasi unsur-unsur yang terdapat dalam spektrum emisi cahaya sampel. Hasil penelitian ini menunjukkan bahwa metode LIBS dapat memberikan analisis cepat dan real-time terkait kandungan
unsur dalam sayur bayam. Pada penelitian ini terdapat unsur-unsur seperti Besi (Fe), Magnesium (Mg), Kalsium (Ca),Natrium (Na), dan Kalium (K) yang terdeteksi dalam kedua sampel yang diuji. Meskipun
metode budidaya yang berbeda digunakan, tidak ada perbedaan yang signifikan dalam jenis unsur yang terkandung. Hanya Konsentrasi unsur-unsur tersebut yang menunjukkan perbedaan.

Kajian Teoritik Persamaan Diferensial Stokastik dan Probability Density Function bagi Gerak Brownian Geometrik Linear dan Nonlinear
S P Tampubolon1, D S Palupi1
Universitas Negeri Jakarta
Abstract
Telah dilakukan kajian teoritik persamaan diferensial stokastik bagi Gerak
Brownian Geometrik linear maupun nonlinear dan dicari penyelesaian fungsi rapat peluangnya (Probability Density Function) serta karakteristiknya. Penelitian yang dilakukan bersifat teoritis. Penelitian dilakukan dengan cara menentukan persamaan diferensial stokastik bagi gerak Brownian geometrik linear maupun nonlinear. Penyelesaian fungsi rapat peluang bagi gerak Brownian geometrik dilakukan dengan menggunakan persamaan Fokker-Planck padanan persamaan diferensial stokastiknya. Gerak Brownian Geometrik linear dengan bagian drift konstan tidak memiliki fungsi rapat peluang yang berlaku pada seluruh x dan t. Gerak Brownian Geometrik non linear akan memiliki fungis rapat peluang yang berlaku pada seluruh x dan t dengan syarat tertentu.

Parennialism Model with Quantum Physics in Teacher Self Transcendence
Nuraeni Asriyanti1, Achmad Buchori2, Ngurah Ayu Nyoman Murniati3

Abstract
The teacher is a moral agent, Maslow^s hierarchy of needs which ends in self-actualization is proven to be unable to bring individuals to find their identity. Problems arise when teachers are oriented towards the love of creatures, material or power. Parennialism with the concept of universal divinity, lowers the perception that the mechanism of the universe including humans can be explained through the nature of matter and energy. A consistent scientific model was found after analyzing the phenomena experienced by the key informant, namely a teacher who proceeded from the initial level to the peak of self-transcendence through the discovery of ^meaning^. His awareness was instilled through an auto-suggestion pattern, then the key informant was guided to find out the biggest negative energy that moved him. The teacher is likened to the property of a particle insulated by a spin magnitude, and the location of the valence electrons with the greatest energy in the uncertainty region is indicated by the electron configuration. Initially fana al-nafs (0), matter (neutrons) is fissioned until meaning is found as energy, the magnitude of meaning energy (E) depends on how many reactions there are, then E=mxc^2, and c is the velocity of emission of β- particle was constant in terms of the moment of inertia. Like the stability of heavy atomic nuclei after fission can be recovered by releasing β- particle emissions, with a ratio of neutron (N) and proton (Z) namely N/Z =1. Surrender leads to the concept of no god (0) but God (1).
