Abstract

This study aims to determine the effect of Advertising and Product Quality Consumer Purchase Decision Against Simpati Product  (Studies in Simpati Card Users in Malang district of East Java). Types of research used in this research is explanatory research  (research  explanation)  that aims  to  explain the  causal relationship between  the causal variables  through hypothesis  testing. Data were collected  through  a questionnaire survey  to  Simpati  card  users  in the city of Malang.  The sampling technique  used was  purposive  sampling  and  obtained a sample of  60  respondents.  To test  the  hypothesis proposed  in this study  used regression analysis. Regression analysis showed that advertising and product quality as well as partial  simultaneously  have  a significant influence  on purchasing decisions. Between the  two variables,  variables  which  have a  dominant  influence  on purchasing decisions  is advertising variable. Based on this analysis, suggestions are given  in  the advertisement Simpati seatraktif delivery must be made possible to be able to attract the attention of consumers, delivery  time and  location of ad placements  should be  tailored to the target  of  the ad,  and  use  resources more messages are generally not accepted by  the or some circles only. Meanwhile,  in terms of the quality of the following suggestions should be used as a consideration which,  always  present  things that are  new  and  innovative  for consumers,  and provide  packages  attractive  prices  and  promotions  are  tailored to the  needs of consumers. Keywords: advertising, product quality, and purchase decision

Abstract

Tulang belakang merupakan penyusun terpenting dalam rangka tubuh manusia, terdapat beberapa penyusun tulang belakang salah satunya adalah lumbar spine. Tulang belakang lumbar terdiri atas beberapa tingkatan yaitu lumbar 1 sampai dengan lumbar 5. Penelitian yang dilakukan akan terfokus pada lumbar 1 sampai dengan lumbar 2. Penelitian dilakukan untuk menganalisis mekanika kontak yang terjadi pada lumbar. Penelitian sebelumnya telah banyak dilakukan secara in vitro dengan menggunakan mayat manusia atau cadaver. Akan tetapi, Terdapat beberapa permasalahan dari pengujian in vitro dalam proses analisis biomekanika kontak. hal tersebut dikarenakan oleh kendala etik dan biaya yang cukup mahal. Oleh karena itu, Metode elemen hingga menjadi solusi alternatif yang mempermudah riset analisis biomekanika kontak pada manusia. Metode elemen hingga dilakukan dengan computerized system yang mana menggunakan bantuan software dalam merekonstruksi visualisasi tulang dan  menganalisis mekanika kontak dengan aplikasi. Proses rekonstruksi dilakukan menggunakan aplikasi mimics 21.0 dengan pengolahan data dari CT-Scan pasien dengan mengubah 2D menjadi 3D. Hasil rekonstruksi akan diproses menggunakan finite element analysis dengan software ansys 2020 R2. Hasil yang didapat tentunya bisa memberikan referensi treatment pada lumbar spine dengan tinjauan variasi mekanika kontak yang terjadi. Optimalisasi rekonstruski perlu dikembangkan untuk mendapatkan hasis analisis mekanika kontak sesuai dengan referensi yang tertera seperti penambahan cortical, nucleus, dan beberapa ligament.

Abstract

Penjualan produk parfum baru sering kali menjadi tantangan dalam dunia ritel, terutama karena banyaknya faktor yang dapat memengaruhi keberhasilan produk di pasar, seperti harga, preferensi pelanggan, dan jumlah pembeli. Penelitian ini bertujuan untuk memprediksi penjualan produk parfum baru dengan menerapkan algoritma k-Nearest Neighbor (k-NN), yang merupakan salah satu metode pembelajaran mesin berbasis instance. Algoritma ini bekerja dengan mengklasifikasikan data baru berdasarkan jarak dari data sebelumnya yang sudah terklasifikasi. Dalam penelitian ini, dataset penjualan parfum yang mencakup atribut harga, jumlah pembeli, dan status penjualan digunakan untuk melatih model. Implementasi algoritma dilakukan dengan menggunakan berbagai nilai k, yaitu k=2, k=3, dan k=4, untuk menentukan jumlah tetangga terdekat yang digunakan dalam proses prediksi. Hasil penelitian menunjukkan bahwa k-NN mampu memberikan prediksi yang akurat terhadap status penjualan produk parfum baru, dengan hasil terbaik diperoleh pada nilai k=3, di mana prediksi status penjualan "Laris" berhasil dihasilkan untuk produk baru yang diuji. Evaluasi kinerja algoritma juga menunjukkan bahwa pemilihan tetangga terdekat berdasarkan jarak Euclidean dan normalisasi data memainkan peran penting dalam meningkatkan akurasi prediksi. Dengan demikian, metode k-NN dapat menjadi solusi yang efektif bagi perusahaan dalam menganalisis data penjualan dan membantu pengambilan keputusan strategis terkait peluncuran produk parfum baru.

Abstract

This research aims to describe teachers' strategies in instilling the values of religious nationalism in the Tsaqofah Islamiyah subject at the Integrated Islamic Senior High School (SMAIT) Al Hikmah Boyolali. This research employs a qualitative approach with a descriptive method. Data collection techniques include observation, interviews, and documentation. The results indicate that in implementing the inculcation of religious nationalism values, Islamic Religious Education (PAI) teachers, particularly in the Tsaqofah Islamiyah subject, create a school culture, serve as role models, and instill values both inside and outside the learning environment. The strategies used include linking Quranic verses related to nationalism, associating the history of Muslim struggles with Indonesia's independence, actively involving students in learning activities, and applying direct practice through assignments both inside and outside the school. Additionally, Pancasila values are integrated into the learning process to provide a deeper understanding of its history and significance. Through these strategies, students exhibit religious nationalism reflected in their love and pride for Indonesia, as well as in their honesty, discipline, responsibility, sincerity, independence, care, hard work, justice, and courage. This study highlights the crucial role of Islamic religious education in shaping students' character based on religious nationalism values. The results of this study show that the strategies implemented by teachers effectively instill religious nationalism values in students, as reflected in their attitudes and daily behavior.

Abstract

Understanding stress distribution on lumbar vertebral endplates is essential for predicting mechanical failure and guiding clinical interventions. Therefore, this study aims to investigate the von Mises stress patterns on the L1/L2 endplates under multiaxial loading using a 3-dimensional finite element (FE) model derived from CT imaging of a healthy 55-year-old male. Anatomical structures were reconstructed in Mimics 21.0, and simulations were conducted in ANSYS Workbench 2023 R2. Material properties for cortical bone, cancellous bone, and intervertebral disc were assigned based on validated biomechanical data. A compressive load of 500 N and multiaxial moments ranging from 2.5 to 10 N•m were applied to simulate physiological movements, while the inferior surface of L2 was fully constrained to reflect realistic boundary conditions. The results showed that the superior endplate experienced the highest von Mises stress, particularly during flexion and lateral bending, indicating increased vulnerability to mechanical overload. Extension loading significantly reduced stress on both endplates, with a 60.54% decrease on the superior endplate and 69.17% on the inferior endplate. Stress distribution was asymmetrical and was influenced by anatomical features, such as cortical thickness and trabecular alignment. These results show the superior endplate as a biomechanically critical region prone to degeneration, emphasizing its importance in implant design, preventive strategies, and risk assessment for microfracture in high-risk populations.
