kondisi pasar. PT Victoeria Vici, sebagai pelaku usaha perhiasan emas custom, menghadapi kendala dalam menentukan estimasi harga jual kepada pelanggan, sebab proses pengerjaan pesanan custom membutuhkan waktu hingga 14 hari, sementara harga emas bergerak fluktuatif dan tidak terstruktur setiap harinya sehingga estimasi harga menjadi tidak akurat dan tidak efektif. Berdasarkan permasalahan tersebut, penelitian ini menerapkan konsep Data Mining dengan algoritma Trend Moment untuk mengestimasi harga emas pada rentang waktu tertentu. Data yang digunakan merupakan data historis harga emas per gram pada PT Victoeria Vici periode Agustus–Oktober 2021 sebanyak 92 data. Tahapan penelitian meliputi pengumpulan data, penentuan variabel X dan Y, eliminasi untuk memperoleh nilai konstanta a dan slope b, serta penerapan persamaan Y = a + bX untuk memperoleh nilai estimasi. Hasil perhitungan menunjukkan nilai a = 720.871,725 dan b = 3,108 sehingga model estimasi mampu menghasilkan proyeksi harga emas yang mendekati pola data historis. Model ini kemudian diimplementasikan ke dalam aplikasi berbasis desktop menggunakan Microsoft Visual Basic 2010 dan basis data Microsoft Access, dilengkapi Crystal Report untuk pencetakan laporan hasil estimasi. Hasil penelitian menunjukkan bahwa algoritma Trend Moment dapat membantu PT Victoeria Vici dalam memperoleh estimasi harga emas secara lebih cepat, konsisten, dan terdokumentasi.
Gold is one of the most sought-after commodities for investment purposes, as it is regarded as a safer instrument compared to stocks and has a selling value that constantly fluctuates with market conditions. PT Victoeria Vici, a custom gold jewelry business, faces difficulty in determining the estimated selling price offered to customers because the production process for custom orders takes up to 14 days, while gold prices move in an unstructured and fluctuating manner every day, making manual price estimation inaccurate and ineffective. Based on this problem, this study applies the concept of Data Mining using the Trend Moment algorithm to estimate gold prices over a certain period of time. The data used is historical daily gold price data per gram from PT Victoeria Vici for the period of August–October 2021, consisting of 92 records. The research stages include data collection, determination of the X and Y variables, elimination to obtain the constant value a and the slope b, and the application of the equation Y = a + bX to obtain the estimated value. The calculation results show a value of a = 720,871.725 and b = 3.108, so that the estimation model is able to produce gold price projections that closely follow the pattern of historical data. This model was then implemented into a desktop-based application using Microsoft Visual Basic 2010 and a Microsoft Access database, equipped with Crystal Report for printing estimation result reports. The results show that the Trend Moment algorithm can help PT Victoeria Vici obtain gold price estimations more quickly, consistently, and in a well-documented manner.

Abstract:This study aims to design the warehouse tata letak at PT MIKRON PRESISI INDONESIA that experiences post-relocation irregularities in production facilities, along with adjustments to the area area and available rental costs.…
ts. The absence of a racking system and clear classification of goods has caused the storage, retrieval, and work safety processes to not run efficiently. The research approach uses a qualitative descriptive method by collecting data through field observations, interviews, and documentation. The tata letak design was carried out by implementing the Activity Relationship Chart (ARC) and Activity Relationship Diagram (ARD) methods, then tested through simulations using FlexSim software with two operator scenarios. The simulation results showed that the proposed alternative tata letak design was able to improve the workflow by grouping goods into seven categories and arranging shelves based on the level of proximity of activities. However, the utilization rate of operators is still relatively low, namely 17.65% and 19.78%, due to the periodic pattern of goods arrival and efficient search times due to a more structured storage system. These findings indicate opportunities for human resource optimization through reducing the number of operators or adjusting workloads. The resulting tata letak design makes a practical contribution to improving warehouse space efficiency and operations, and can be used as a reference for applications for companies with similar characteristics.

Abstract:This study aims to examine the effect of implementing the Sam'iyah Syafawiyah method based on a communicative approach on students' self-confidence in speaking Arabic through a library research approach. The study employs…
s a qualitative method with a systematic literature review, analyzing and synthesizing scientific sources including books, international and national journals, articles, proceedings, and relevant research findings. Data sources were obtained from scientific databases such as Google Scholar, JSTOR, ScienceDirect, ERIC, and national digital repositories. The findings consistently demonstrate that the Sam'iyah Syafawiyah method integrated with the communicative approach has a positive and significant influence on students' self-confidence in speaking Arabic. This effect operates through four main mechanisms: (1) repetitive drilling builds mastery experience; (2) native speaker audio models provide vicarious experience; (3) the communicative approach reduces affective filters; and (4) intensive practice promotes automaticity in Arabic speech production. This study concludes that the integration of both methods constitutes an effective and recommended pedagogical strategy for improving self-confidence in Arabic speaking.
Penelitian ini bertujuan untuk mengkaji pengaruh penerapan metode Sam'iyah Syafawiyah berbasis pendekatan komunikatif terhadap kepercayaan diri peserta didik dalam berbicara bahasa Arab melalui pendekatan library research (studi kepustakaan). Penelitian menggunakan metode kualitatif dengan kajian literatur sistematis, yakni menganalisis dan mensintesis berbagai sumber ilmiah berupa buku, jurnal nasional dan internasional, artikel, prosiding, dan hasil penelitian yang relevan. Sumber data diperoleh dari berbagai basis data ilmiah seperti Google Scholar, JSTOR, ScienceDirect, ERIC, dan repositori digital nasional. Hasil kajian secara konsisten menunjukkan bahwa metode Sam'iyah Syafawiyah yang diintegrasikan dengan pendekatan komunikatif memberikan pengaruh positif dan signifikan terhadap kepercayaan diri peserta didik dalam berbicara bahasa Arab. Pengaruh ini bekerja melalui empat mekanisme utama: (1) latihan drill berulang membangun mastery experience; (2) model audio native speaker memberikan vicarious experience; (3) pendekatan komunikatif menurunkan filter afektif; dan (4) latihan intensif mendorong otomatisasi produksi ujaran bahasa Arab. Penelitian ini menyimpulkan bahwa integrasi kedua metode tersebut merupakan strategi pedagogis yang efektif dan direkomendasikan untuk meningkatkan kepercayaan diri berbicara bahasa Arab.
Abstract:This study explores how influencer marketing shapes digital identity and spatial relations in Makassar, Indonesia, through a spatially grounded urban ethnography approach. This framework enables a deep reading of how urban…
an residents engage with digital practices to navigate symbolic and spatial exclusion generated by influencer content. Through social media observation, narrative interviews, and the tracing of urban locations featured in visual representation, the study finds that influencer marketing does not merely sell products—it also reproduces social hierarchies through aesthetic spatiality and the logic of visibility.
Yet, amid such exclusions, marginalized communities deploy diverse tactics of resistance, including visual reengineering, the use of alternative locations, and digital irony that disrupt dominant narratives. These findings suggest that digital identity is not passively consumed but actively negotiated through concrete and often unexpected spatial relations. Drawing on Lefebvre’s theory of the production of space, Urry’s concept of digital mobilities, and Gandy’s politics of infrastructure, the study shows how cities and digital spaces co-constitute a contested symbolic terrain.
The article’s main contribution lies in advancing a Global South perspective, where digital technologies and aesthetics are practiced contextually and do not always conform to the logics of global capitalism. This research underscores that urban—and digital—space is not solely produced from above, but also from below, through the everyday agency of ordinary citizens.
Abstract:This study explores how marginalized communities in Makassar construct and sustain their life rhythms amidst the temporal pressures shaped by infrastructure systems, mobility regimes, and urban development logics. Employing…
ing a space- and time-based urban ethnographic approach, the research traces residents’ daily tactics, rhythmic narratives, and spatial practices in navigating mobility exclusion and the accelerating, non-inclusive urban pace.
Field findings reveal that residents engage in various forms of micro-resistance—such as adjusting selling hours, utilizing interstitial moments in urban space, and cultivating social rhythms that diverge from technocratic logics. Within temporalities not governed by state or capital, urban spaces are collectively reproduced from below, positioning spatial production as a bottom-up process rather than a top-down imposition.
The study contributes theoretically by advancing Lefebvre’s rhythmanalysis, Urry’s notion of differential mobility, and Gandy’s political ecology of infrastructure within the context of Global South cities. By foregrounding time as a critical analytical lens, the research expands our understanding of how power operates temporally in urban life, and how residents negotiate this power through their everyday rhythms.
Ultimately, this research offers a new perspective for interpreting urban dynamics—not only through spatiality but also through socially produced temporalities.
Abstract:This study explores how Bugis-Makassar women construct and navigate plural reproductive knowledge in response to abortus imminens (threatened miscarriage), drawing on Talcott Parsons’ AGIL framework to analyze the sociocultural…
ocultural functions of care practices. Based on ethnographic fieldwork in Makassar, Indonesia, including interviews and participant observation with ten pregnant women, the study reveals that reproductive behavior is shaped by adaptive strategies (A), collective goals (G), moral integration (I), and intergenerational transmission of norms (L). Rather than following a singular medical logic, women mobilize syncretic forms of care that blend biomedical treatment, spiritual rituals, and ancestral taboos. These plural responses reflect not only epistemic hybridity but also reproductive governance enacted through kinship, religious authority, and clinical institutions. Women's agency is expressed not through open resistance, but through strategic moral navigation and embodied alignment with normative expectations—a form of what Mahmood terms the ethics of self-formation. The findings challenge biomedical-centric approaches to maternal health and highlight the need for culturally responsive interventions that respect local logics of risk, protection, and care. This study contributes to sociological debates on medical pluralism, moral regulation, and the reproduction of gendered knowledge in the Global South.

lus Pricing to evaluate supply chain effectiveness and determine appropriate product pricing. Data were collected through observation, interviews, and documentation involving 50 respondents, consisting of fish farmers, middlemen, wholesalers, and market traders. The results indicate that the Pangasius distribution system still involves multiple intermediaries, resulting in relatively weak bargaining power for fish farmers. The distribution process takes approximately 1–2 days and is constrained by limited cold storage facilities, which affects product quality. Cost analysis shows that the cost of production is IDR 20,239.15 per kg, while the ideal selling price is IDR 22,263.06 per kg, with a profit margin of 10%. Improvements in the distribution system, better access to market information, and enhanced logistical support are necessary to increase distribution efficiency and improve farmers’ profitability.
