Abstract

Abstrak−Tindakan melecehkan orang lain melalui penggunaan teknologi informasi dan komunikasi seperti media sosial, ponsel, dan video dikenal sebagai bullying. Bullying adalah perilaku agresif. Bullying dapat berdampak kepada gangguan psikologis seperti stres. Dalam ilmu psikologi, mengukur tingkat stres seseorang merupakan salah satu cara penerapan sistem pakar. Penelitian ini menggunakan metode forward chaining. Forward chaining adalah metode yang menarik kesimpulan dari data atau fakta. Forward chaining dimulai dengan informasi yang sudah ada dan menggunakan aturan untuk membuat kesimpulan untuk mendapatkan lebih banyak informasi sampai tujuan tercapai.data dikumpulkan dengan teknik kuesioner yang menghasilkan 40 poin aspek penilaian. Hasil penelitian menunjukkan perilaku bullying memiliki hubungan signifikan pada tingkst stres seseorang yang dapat mempengaruhi psikologis. Semakin berat gejala yg didapat semakin tinggi tingkat stress yang dialami. Kata Kunci: Perilaku bullying, Stress, Psikologis, Forward chaining Abstract− The act of harassing other people through the use of information and communication technologies such as social media, cell phones and videos is known as bullying. Bullying is aggressive behavior. Bullying can have an impact on psychological disorders such as stress. In psychology, measuring a person's stress level is one way of implementing an expert system. This research uses the forward chaining method. Forward chaining is a method that draws conclusions from data or facts. Forward chaining starts with existing information and uses rules to make conclusions to get more information until the goal is achieved. Data is collected using a questionnaire technique which produces 40 points of assessment aspects. The results showed that bullying behavior has a significant relationship to a person's stress level which can affect psychologically. The more severe the symptoms are, the higher the level of stress experienced. Keywords: Bullying behavior, Stress, Psychological, Forward chaining

Abstract

Abstract−This study aims to analyze noise levels and provide recommendations for noise control. Noise tests were conducted using a sound level meter, in accordance with the SNI 8427-2017 standard, at three sampling points. Data analysis covered vehicle volume (in emp), average noise levels (Ls), correlation tests, and control recommendations. Data processing was carried out using Microsoft Excel, SPSS (25), and Sketchup software. The results showed that the highest vehicle volume reached 2,090 vehicles per hour with a composition percentage of motorcycles (MC) at 69.3%, light vehicles (LV) at 56.2%, and heavy vehicles (HV) at 9.4%, in line with the emp values of MKJI (1997). The noise level (Ls) reached a fairly high level, hitting 72.5 dB. There is a moderate to very strong relationship between vehicle volume and noise levels (with correlation values ranging from 0.450 to 0.874). To control the noise, it is suggested to add vegetation barriers such as Acacia trees and Sebe shrubs, which can enhance the effectiveness of existing barriers in reducing noise to below the quality standard as per the Minister of Environment Regulation No. 48 of 1996 for residential and commercial areas

Abstract

3D Printing Fused Deposition Modeling (FDM) is the printing of thermoplastic material layer by layer to form a three-dimensional product in which the adhesion between layers must be well controlled to obtain high mechanical performance and product integrity. The research aims to investigate the influence of the nozzle temperature, table temperature, and filling model on the mechanical strength and surface quality of the product. The PLA filament used in this study, the experimental data capture design using the Taguchi L9 with factor and level (2)4 two nozzle temperature parameters, two model infill parameters, two print speed parameters, and printer table temperature. The durability and quality of the product are the focus of this compilation, and data analysis using robust statistical methods of S/N Ratio design. The relationship of rigidity to mechanical force is also discussed. The temperature of the nozzle becomes a major influence on the firmness of the product for the surface hardness which is a big influence not of the temperature but of the model of the infill
