Abstract

The sale of staple food products at Nafhanmart Store, Cirebon Regency, includes essential household items such as rice, cooking oil, sugar, and flour, which maintain stable demand as basic necessities. This study focuses on improving sales clustering models at Nafhanmart using the Fuzzy C-Means (FCM) algorithm, a prominent method in data mining. Key factors influencing sales include price, sales volume, demand, and remaining stock. Accurate clustering analysis is vital for strategic inventory management and profit maximization. The research applies the Knowledge Discovery in Database (KDD) methodology, encompassing data selection, preprocessing, transformation, FCM implementation, and evaluation using the Davies-Bouldin Index (DBI). Attributes analyzed include price, sales volume, demand, and remaining stock. The FCM algorithm clusters data based on patterns, with DBI evaluating clustering quality and determining optimal clusters. Data analysis and visualization were conducted using RapidMiner. Results show that the FCM algorithm achieves optimal clustering quality with a DBI score of 0.452 for two clusters, outperforming three clusters (DBI 0.474) and four clusters (DBI 0.536). Price and demand are identified as critical factors influencing clustering outcomes. These findings enhance the clustering model, offering actionable insights for inventory management and sales strategy, while showcasing the FCM algorithm's adaptability for other SMEs to support data-driven decision-making.

Abstract

Inflation is a general tendency to increase the prices of goods and services, and it happens all the time. when the prices of domestic goods and services rise, inflation will rise. Depreciation causes the prices of goods and services to rise. Uncontrolled inflation can result in losses for society and the government. Therefore, an appropriate study is needed to map the dynamics of inflation in a region. One way to map the inflation rate is clustering. Clustering is dividing data into groups with the same characteristics. The author took the initiative to analyze the urban inflation rate in Indonesia from 2020 to 2022. The data is sourced from the Central Statistics Agency (BPS) website. This analysis uses the K-Means Clustering method with 5 clusters. the group with the highest inflation is in cluster 0, the high inflation group is in cluster 1, the moderate inflation group is in cluster 2, the low inflation group is in cluster 3, and the lowest inflation is in cluster 4. by categorizing the inflation rate of cities in Indonesia, it can be seen which cities in Indonesia have very high, high, medium, low and very low inflation rates.

Jenis penelitian ini adalah penelitian lapangan (field research) dengan menggunakan metode penelitian deskriptif. Sumber data yang digunakan meliputi dokumen, rekaman, arsip, hasil wawancara, observasi langsung, observasi partisipan dan perangkat fisik seperti video dan gambar. Metode pengumpulan data yang digunakan adalah (1) dokumentasi; (2) observasi; dan (3) wawancara. Teknik analisis data dalam penelitian ini adalah: (1) reduksi data; (penyajian data); dan (3) penarikan kesimpulan. Implementasi kesantunan berbahasa Indonesia dalam Pendidikan Agama Islam terdiri dari empat tahapan yang dilakukan yaitu, perencanaan, pengorganisasian, pelaksanaan, dan evaluasi. Faktor penghambat dalam implementasi kesantunan berbahasa Indonesia dalam Pendidikan Agama Islam karena adanya pelanggaran maksim atau indikator kesantunan, karena hal ini sering terjadi pada saat proses pembelajaran berlangsung. Sedangkan faktor pendukungnya adalah, adanya sumber daya manusia yang mumpuni, yaitu guru-guru pengajar memiliki pengalaman mengajar yang cukup lama sehingga mampu menyampaikan pemahaman kepada peserta didik tentang pentingnya berbahasa Indonesia yang santun dalam kehidupan sehari-hari, khususnya di lingkungan sekolah. Tersedianya bahan ajar dan media pembelajaran yang memadai. Antusiasme peserta didik untuk mengikuti mata pelajaran PAI karena memiliki keterkaitan dengan materi agama yang telah mereka pelajari di rumah atau pondok. Motivasi dari orang tua, teman dan saudara untuk selalu berbahasa Indonesia santun dimanapun berada, sehingga akan membantu keberhasilan program penerapan kesantunan berbahasa Indonesia dalam Pendidikan Agama Islam.

Abstract

In today's digital age, social media use has become an integral part of teenagers' lives. However, increased access to information and online communication also brings new challenges, especially in terms of digital safety and media etiquette. School adolescents, as active users of social media, often lack an adequate understanding of the risks that can arise from their digital activities. This study aims to provide a comprehensive understanding of the importance of digital safety and the application of ethics in social media among teenagers. The method used is a literature study combined with an educational approach based on learning and training modules. The results of the study show that most teenagers are not aware of the importance of personal data protection, password security, and the risk of spreading false information or hoaxes. In addition, the lack of ethics in communicating on social media can lead to social conflicts and privacy violations. Therefore, a systematic educational approach is needed to equip teenagers with the knowledge and skills to maintain digital security and act ethically in the digital space. This educational effort needs to involve the role of teachers, parents, and school policies that support digital literacy as a whole.

Abstract

In the digital era, an archival information system is an important requirement in supporting effective and efficient administrative governance in the village government. Many villages in Indonesia still use a manual archive recording system that is vulnerable to data loss, physical damage to documents, and the slow process of retrieving information. This service program aims to implement a digital-based archival information system in the village government to improve administrative performance and public services. The methods used include partner needs analysis, system design, software implementation, user training, and evaluation of results. The developed system enables document digitization, archive grouping, and fast data search, and is equipped with security features to maintain information integrity. The results of the implementation showed that village officials were able to understand and operate the system well after the training. The information system significantly speeds up the document search process and reduces the risk of data loss. In addition, the implementation of the system also has an impact on improving transparency, accountability and professionalism in services to the community. In conclusion, the implementation of a digital-based archival information system is an innovative and applicable solution to address the challenges of modern village archive management.
