Mineralogical Characteristics and Critical Stress Variation in Rock Samples from Bukit Kunyit, Bandar Lampung
Full text linkMineralogy is essential for understanding rock formation processes and their physical properties, including critical stress. Critical stress values can be estimated using unconfined compressive strength (UCS) measurements, which depend on the modulus values of the minerals present. This study explores the mineralogical characteristics of rock samples from Bukit Kunyit, Bandar Lampung City, and Lampung through X-ray diffraction (XRD) and petrographic analysis. Macroscopic observations revealed two visually distinct rock samples: one with a bright color (Sample 1) and another with a darker hue (Sample 2). Despite these color differences, XRD analysis showed that both samples have the same mineral composition, including Anorthoclase, Cristobalite, Tridymite, and Muscovite, indicating a felsic (silica-rich) nature. Differences were noted in the crystallographic forms of Muscovite and Quartz content, with Sample 2 having a higher Quartz concentration. These mineralogical variations correlate with the observed differences in critical stress, with Sample 1 exhibiting a lower critical stress (20.98 MPa) than Sample 2 (35.05 MPa)
Faktor-Faktor dan Preferensi Pergerakan Pengguna Layanan Online Food Delivery Di Kota Bandung
No full textThe advancement of information and communication technology has proliferated globally, as demonstrated by the emergence of various startups such as Gojek and Grab. Among the principal services provided by these enterprises is online food delivery, which facilitates the convenient ordering of food and beverages via mobile devices. This technological transformation not only influences patterns of human mobility but also shapes consumer preferences concerning the utilization of online food delivery services. This research employs descriptive analysis and logistic regression analysis as its methodological approach. The results indicate that preferences for using online food delivery services are determined not solely by socioeconomic factors and technological familiarity, but are also significantly influenced by social interactions and lifestyle considerations. Consequently, online food delivery services have not entirely supplanted the custom of dining in at restaurants; rather, they function as a complementary option that addresses the quotidian needs of consumers

Full text linkPenelitian ini membahas penerapan standar IEEE Std 1547-2018 dalam proses interkoneksi Pembangkit Listrik Tenaga Surya (PLTS) ke sistem distribusi 20 kV, dengan studi kasus menggunakan sistem uji IEEE 14-bus. Analisis dilakukan dengan pendekatan metode Newton-Raphson melalui perangkat lunak ETAP untuk mengevaluasi dampak integrasi PLTS terhadap tegangan, rugi-rugi daya, proteksi, kualitas daya, dan keamanan sistem. Simulasi awal menunjukkan bahwa kondisi basecase mengalami tegangan kritis di bus 13 dan 14. Setelah interkoneksi PLTS-DG 5 MW, terjadi perbaikan tegangan dan penurunan rugi daya. Sistem juga memenuhi batas teknis kualitas daya (THD, step voltage, dan DC injection) serta proteksi sesuai batas waktu trip yang ditetapkan standar. Hasil penelitian menunjukkan bahwa interkoneksi PLTS dapat meningkatkan efisiensi dan stabilitas sistem distribusi jika dilakukan dengan perencanaan yang tepat, serta memenuhi semua kriteria teknis dalam IEEE Std 1547-2018.
 
DAMPAK AGLOMERASI KAWASAN PERDAGANGAN DAN JASA ANTASARI BANDAR LAMPUNG TERHADAP SOSIAL DAN EKONOMI BERDASARKAN PERSEPSI MASYARAKAT
No full textThis study analyzes the social and economic impacts of agglomeration in the Antasari Trade and Service Corridor in Bandar Lampung, based on local community perceptions. As a rapidly developing urban zone, the corridor has transformed from a residential area into a hub of commercial and service activities since 2015. Using a quantitative deductive approach, data were collected through surveys and field observations involving 100 respondents from four surrounding sub-districts. Statistical inference and scalogram analysis were applied to assess the significance and intensity of impacts. The results indicate that agglomeration has led to notable changes in daily activities, consumer behavior, entrepreneurial interest, and comfort levels due to increased traffic congestion, noise, and informal street trading. Economically, while it has not significantly increased average income, the development has enhanced job opportunities, business prospects, and land value. The social impact was found highest in Kedamaian, whereas the economic impact peaked in Tanjung Baru. The findings highlight the dual nature of agglomeration and provide policy insights for sustainable and socially equitable urban planning in growing metropolitan areas. The recommendation from this study is the need for government regulations regarding the development of trade and service areas to minimize negative impacts in the future
