Abstract

Let (R, +, ·) be a ring with unity. An element in R is called a cleanelement if it is the sum of a unit element and an idempotent element. A ring R is calleda clean ring if all elements in R are clean elements. The notion of a clean element wasgeneralized to a clear element by replacing the idempotent element with a unit-regularelement. An element in R is called a clear element if it is the sum of a unit elementand a unit-regular element. A ring R is called a clear ring if all elements in R are clearelements. In this paper, we study the new properties of clear elements in a ring andclear properties in certain special rings, such as opposite rings, quotient rings, cornerrings, Morita rings, and group rings.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh Risk Management Committee (RMC), leverage, dan ukuran perusahaan terhadap nilai perusahaan pada emiten pertambangan yang terdaftar di Bursa Efek Indonesia periode 2022–2024. Nilai perusahaan merupakan salah satu indikator penting yang mencerminkan keberhasilan perusahaan dalam meningkatkan kesejahteraan pemegang saham serta menjadi dasar pertimbangan investor dalam mengambil keputusan investasi. Dalam menghadapi ketidakpastian bisnis, perusahaan pertambangan dituntut untuk menerapkan manajemen risiko yang efektif, mengelola struktur pendanaan secara optimal, serta memanfaatkan ukuran perusahaan untuk meningkatkan daya saing dan menciptakan nilai perusahaan. Oleh karena itu, keberadaan Risk Management Committee, tingkat leverage, dan ukuran perusahaan dipandang sebagai faktor yang dapat memengaruhi nilai perusahaan. Penelitian ini menggunakan pendekatan kuantitatif dengan metode analisis statistik. Populasi penelitian adalah seluruh emiten pertambangan yang terdaftar di Bursa Efek Indonesia selama periode 2022–2024. Teknik pemilihan sampel menggunakan purposive sampling sehingga diperoleh 60 data penelitian. Analisis data dilakukan menggunakan regresi data panel dengan bantuan aplikasi EViews melalui tahapan pemilihan model estimasi, uji asumsi klasik, analisis regresi, uji parsial (uji t), uji simultan (uji F), dan uji koefisien determinasi. Hasil penelitian menunjukkan bahwa secara parsial Risk Management Committee tidak berpengaruh terhadap nilai perusahaan. Sementara itu, leverage dan ukuran perusahaan berpengaruh terhadap nilai perusahaan. Secara simultan, Risk Management Committee, leverage, dan ukuran perusahaan berpengaruh terhadap nilai perusahaan pada emiten pertambangan yang terdaftar di Bursa Efek Indonesia. Hasil penelitian ini diharapkan dapat menjadi referensi bagi perusahaan, investor, dan peneliti selanjutnya dalam memahami faktor-faktor yang memengaruhi nilai perusahaan.

Abstract

The purpose of this study is to evaluate the effectiveness of the Andal by Taspen application in improving the quality of pension services and its usefulness from a maslahah mursalah perspective at PT Taspen (Persero) Jember Branch Office. This study used a qualitative method through interviews with employees of PT Taspen (Persero) Jember Branch Office and pension participants who use the Andal by Taspen application. The results show that the Andal by Taspen application helps pension services by providing easy access to information and services such as checking pay slips, information about salaries and THT, online file collection, attendance, and participant verification. However, some elderly participants faced problems such as server errors and difficulties with facial verification. From a maslahah mursalah perspective, the Andal by Taspen application provides easy access to services, saves time and energy, assistance in understanding digital services, data security, and ease of obtaining information and services related to participants' financial rights. The Andal by Taspen application can be considered quite useful and beneficial for pension participants. However, to increase its benefits to all users, it is necessary to improve system stability, improve verification features, and provide ongoing assistance.

Abstract

This study aims to describe and analyze the digital marketing strategies implemented by Dasilva Batik, a batik fashion MSME in Malang City established in 2017 with the tagline "Wearing Batik Doesn't Have to Mean a Shirt" in an effort to boost brand awareness and consumer purchase interest. The digital marketing activities examined encompass platforms such as TikTok, Shopee, Instagram, and WhatsApp Business, covering live streaming, daily content production, a project-based ordering system, and participation in exhibitions and media coverage. A qualitative descriptive approach utilizing a case study method was employed. Data collection involved observation, in-depth interviews with the founder and marketing team, and document analysis using the SWOT (Strengths, Weaknesses, Opportunities, Threats) matrix. The findings reveal that Dasilva Batik’s key strengths lie in product differentiation as a pioneer of batik jackets, comprehensive business legality, and extensive partnership networks and media exposure. However, a fundamental weakness lies in the management of digital content, which lacks a structured schedule and a data-driven approach. The "local pride" trend among the youth and the rise of short-video platforms present major opportunities, while aggressive market competition and changing platform algorithms pose dynamic threats. The study recommends developing a structured content calendar and implementing storytelling rooted in cultural values ​​to optimally convert brand exposure into increased brand awareness and consumer purchase interest.
