Abstract

Penelitian ini bertujuan untuk menghasilkan alat monitoring suhu dan tekanan udara di ruang isolasi kelas negatif rumah sakit berbasis Internet of Things (IoT) yang dapat digunakan oleh tenaga kesehatan untuk memantau suhu dan tekanan udara di ruangan tersebut. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif. Teknik pengumpulan data dilakukan dengan cara studi literatur dan observasi. Teknik analisis data dilakukan dengan cara menghitung nilai rata-rata dan nilai error dari alat yang dibuat. Alat monitoring suhu dan tekanan udara di ruang isolasi kelas negatif berbasis IoT dibuat menggunakan sensor BMP280, mikrokontroler ESP32, LCD, aplikasi monitoring di komputer menggunakan Firebase, dan aplikasi monitoring di smartphone menggunakan Kodular. Alat monitoring suhu telah diuji dan dibandingkan hasilnya dengan alat ukur Thermohygrometer yang menghasilkan nilai error sebesar 0,24%. Alat monitoring tekanan udara juga telah diuji dan dibandingkan hasilnya dengan alat ukur Magrfhelic yang menghasilkan nilai error sebesar 0,51%. Hasil penelitian menunjukkan bahwa alat monitoring suhu dan tekanan udara yang dibuat mempunyai hasil pengukuran yang mendekati dengan alat pembanding aslinya, sehingga dapat digunakan oleh tenaga kesehatan untuk memantau suhu dan tekanan udara di ruang isolasi kelas negatif rumah sakit.

Abstract

This qualitative inquiry explores how marketing strategies shape consumer purchasing decisions at PT Poin Medika in Yogyakarta, Indonesia. The study is grounded in the view that purchasing behavior is not merely a reaction to promotional cues, but a negotiated process influenced by perceptions, trust, and experiential signals embedded in everyday consumer brand interactions. As patient-oriented service industries grow increasingly competitive, understanding these subtler decision drivers becomes essential for crafting strategies that resonate authentically with local consumers. Using a qualitative descriptive design, data were gathered through semi-structured interviews with customers and key marketing personnel, complemented by on-site observations. All transcripts and field notes were coded and analyzed using NVivo to identify recurring patterns and relational themes. The NVivo analysis revealed three dominant clusters trust-anchored communication, where transparent information and empathetic tone strengthened perceived reliability; service experience cues, including staff attentiveness and perceived service efficiency, which shaped emotional comfort and purchase readiness; and value interpretation, reflecting how consumers evaluated the alignment between pricing, service quality, and personal health needs. The synthesis of these themes indicates that effective marketing at PT Poin Medika is less about persuasive tactics and more about cultivating relational assurance and meaningful service encounters. The findings suggest that marketing strategies rooted in clarity, human warmth, and consistent service delivery foster stronger purchase intentions. This study underscores the strategic importance of experiential and trust-based communication in guiding consumer decision-making within healthcare-related service contexts.

Abstract

This study examines how weather patterns, climate shifts, and seasonal rainfall variations shape the sales volume and revenue stability of micro, small, and medium enterprises (MSMEs), with a focused case on Kulit Lumpia Bunga Terate in Kasihan, Bantul, Yogyakarta. The inquiry departs from the premise that small food-based enterprises operate within fragile ecological and market environments, where fluctuating humidity, temperature, and rainfall subtly influence production quality, consumer traffic, and operational continuity. A qualitative approach was chosen to capture these lived realities in a manner that quantitative measures alone cannot express. Data were collected through in-depth interviews with owners, production workers, and local suppliers, supported by field observations during both dry and rainy periods. All qualitative materials were processed and analyzed using NVivo, allowing systematic coding and thematic patterning. The NVivo outputs highlighted three interlinked thematic domains moisture-sensitive production challenge, where humidity and rainfall affected dough consistency, drying time, and defect rates; consumer flow fluctuations, driven by changes in foot traffic, weather-related mobility, and shifting consumption habits during prolonged rains; and adaptive economic responses, including informal inventory strategies, flexible pricing, and selective product diversification to buffer revenue drops. The synthesis of these themes suggests that the enterprise’s economic resilience is strongly tied to its capacity to anticipate and adapt to environmental variability. The findings underscore that climate-responsive production practices, paired with context-specific marketing adjustments, play a crucial role in sustaining MSME performance amid increasingly unpredictable weather conditions.
