Abstract

This study aims to analyze the factors that influence students' difficulty in reading the beginning by taking the object of research at Suko 1 Sidoarjo State Elementary School. While the type of research selected is a case study with 2 subjects. Data was collected through observation, interview, and documentation techniques. Then analyzed using the interactive analysis of the Miles model, namely data condensation, data presentation, drawing conclusions, and data verification. Test the validity of the data using triangulation techniques. The results showed that early reading difficulties were related to omitting words, replacing words, letters, stammering spelling, pronouncing wrong words, and pronouncing patent letters. These difficulties are influenced by four internal factors, namely daily activities, understanding of the material, psychological conditions, and learning motivation. External factors that affect learning difficulties in early reading are the role of the teacher and the family environment.

Abstract

This study aims to analyze market structure and pricing strategies for new products in the context of monopolistic competition through a literature review approach. The method applied is a systematic literature review of scholarly articles, textbooks, and empirical research published between 2020 and 2025. The findings reveal that in monopolistic markets, firms possess limited pricing power due to product differentiation and demand elasticity. Classical strategies such as skimming and penetration pricing remain relevant but have evolved in the digital era into data-driven practices such as dynamic pricing and machine learning–based optimization. While these strategies enhance revenue potential, they also introduce risks such as algorithmic collusion and fairness issues that demand regulatory oversight. The implications highlight the necessity for firms to adopt adaptive, data-driven, and ethically responsible pricing strategies, while policymakers should ensure proper regulation to maintain healthy market competition.

Abstract

Many shapes and patterns on the human body might be considered a person's uniqueness or feature since they differ significantly from one another, one of which is the shape of the face. In computer vision, the shape of a face is divided into five fundamental shapes. The experiment in this paper provides a model based on the final layer of the results of retraining InceptionV3, a Convolutional Neural Network (CNN) architecture for classifying human face photos. Inspired by human neural networks, this method generally works well for face recognition and computer vision research. This research begins with the stages of data acquisition, data exploration, classification, and evaluation. Retraining is performed to improve accuracy using the distance and angle of facial landmarks. The results are compared to other classification methods, including linear discriminant analysis (LDA), support vector machine with a linear kernel (SVM-LIN), support vector machine with a radial basis function kernel (SVM-RBF), artificial neural networks or multilayer perceptrons (MLP), and k-nearest neighbors. The facial dataset used consists of 747 photos, divided into five categories: oval, round, square, heart, and oblong. The Canny edge detector approach is utilized to enhance CNN accuracy, which has been effectively improved through training and testing. The maximum accuracy achieved was 91.7% based on training and testing at 85%-98%. This demonstrates that the outcomes of inceptionV3 retraining may appropriately adapt training data and outperform alternative classification techniques without the need to specify the function of certain features during the model training process.

Abstract

Pembiayaan dalam penyelenggaran perkeretaapian sudah menjadi rahasia umum membutuhkan pendanaan yang massif. Pengabdian Masyarakat ini dilaksanakan dalam bentuk kuliah umum bertempat di Politeknik Negeri Madiun, yang dihadiri oleh mahasiswa D IV Perkeretaapian tingkat 4 dan dosen. Kesimpulan pada pengabdian ini adalah 1. Pembangunan dan pengoperasian kereta api tidak dapat dipungkiri membutuhkan dana yang masif, sedangkan return of investmennya sangat lambat. 2. Penyelenggaraan perkeretaapian pada awalnya dilaksanakan operator yang dibawah Pemerintah yang kinerjanya semakin memburuk hingga sampau pada kondisi yang semakin buruk baik dari sisi pelayanan maupun perawatan sarana dan prasarananya. 3. Privatisasi operator diperlukan untuk memperbaiki kondisi pelayanan dan memunculkan persaingan yang sehat. 4. Fragmentasi penyelenggaraan perkeretaapian di Indonesia dapat dikatagorikan belum berhasil baik secara vertical unbundling maupun horizontal unbundling. 5. Implementasi Kewajiban Pelayan Publik (PSO) dilaksanakan dengan sistem kontrak pertahun antara operator dan Pemerintah, yang diverifikasi setiap akan menarik pembayaran kontrak dengan melakukan evaluasi realisasi dalam hal: Fasilitas yang diberikan, Frekuensi yang diperjanjikan, tempat duduk yang diperjanjikan dan stamformasi kereta harus sesuai 6. Besaran PSO yang digelontorkan Pemerintah semakin lama semakin besar, yang seharusnya dengan semakin membaiknya kondisi ekonomi masyarakat maka nilai PSO harusnya semakin menurun

Abstract

ABSTRAKHutan merupakan aset alam yang melimpah dengan keanekaragaman hayati. Hutan berperan menyediakan hasil kayu dan bahan selain kayu, di antaranya tanaman obat. Keberagaman kondisi lingkungan memberikan kesempatan berbagai jenis tumbuhan mendiami ekosistem, termasuk jenis tumbuhan bawah. Tumbuhan bawah merupakan bagian pokok lapisan tumbuhan di bawah kanopi hutan, selain dari permudaan pohon, yang terdiri atas rumput, herba dan semak belukar. Tanaman ini berfungsi mempertahankan kestabilan ekosistem hutan. Penelitian ini bertujuan memperoleh data potensi keanekaragaman, komposisi dan struktur jenis tumbuhan bawah berkhasiat obat di tiga blok RPTN Coban Trisula, kawasan Taman Nasional Bromo Tengger Semeru (TNBTS) yaitu Blok Pusung Bledok Pasang, Blok Beji, dan Blok Jemplang. Penentuan petak contoh menggunakan teknik purposive sampling dengan karakteristik jenis tumbuhan bawah berkhasiat obat yang ditemukan di lantai hutan, lantai hutan terbuka dan tepi jalan, mulai ketinggian 1500, 2000, dan 2200 mdpl. Metode analisa vegetasi menggunakan teknik jalur berpetak (quadrat line transect). Setiap blok yang ditetapkan terdiri dari 5 petak contoh berukuran 2 x 2 meter. Jarak antar petak contoh 20 meter. Jumlah keseluruhan unit sampel yang digunakan 15 petak contoh dengan luas total 60 m2. Hasil penelitian menunjukkan terdapat 18 jenis tumbuhan bawah berkhasiat obat dari 11 famili yang tersebar di 3 blok penelitian. Dari ketiga blok, famili Asteraceae paling banyak ditemukan. Nilai indeks keanekaragaman jenis tergolong sedang. Blok Pusung Bledok Pasang memiliki nilai 1.01 (sedang), Blok Beji 2 (sedang) dan Blok Jemplang 2.37 (sedang). Nilai indeks kemerataan jenis di Blok Pusung Bledok Pasang 0.34 (tertekan), Blok Beji 0.70 (labil), dan Blok Jemplang 0.84 (stabil).ABSTRACTForests are natural assets that are abundant with biodiversity. Forests play a role in providing wood products and materials other than wood, including medicinal plants. The diversity of environmental conditions provides opportunities for various types of plants to inhabit the ecosystem, including types of undergrowth plants. Undergrowth is the main part of the plant layer under the forest canopy, apart from tree regeneration, which consists of grass, herbs and shrubs. This plant functions to maintain the stability of the forest ecosystem. This research aims to obtain data on the potential diversity, composition and structure of understory plants with medicinal properties in three blocks of the Coban Trisula RPTN, Bromo Tengger Semeru National Park (TNBTS) area, namely the Pusung Bledok Pasang Block, the Beji Block and the Jemplang Block.
