Abstrak - Indonesia merupakan salah satu negara yang kaya akan potensi kelautan dan perikanan sehingga banyak sekali masyarakat yang gemar memelihara ikan hias.  Meski demikian, dalam pemeliharaan ikan hias masih ditemui beberapa kendala. Salah satunya adalah kesulitan dalam mengontrol pakan ikan secara realtime, terutama ketika pemelihara tidak bisa melakukan secara langsung di lokasi. Demikian juga dengan pengontrolan kualitas air yang cukup menyulitkan. Dengan adanya teknologi informasi yang semakin berkembang, dapat membantu peternak dalam melakukan kontrol jarak jauh menggunakan Internet of Things (IoT). Tujuan penelitian ini adalah untuk mengembangkan sistem pakan otomatis serta monitoring Total Disslove Solid  (TDS), sehingga kualitas air akuarium dapat dipantau secara remote dengan memanfaatkan IoT. Hasil dari pengujian  menunjukkan bahwa sensor TDS dapat mengidentifikasi kualitas air akuarium, terutama terkait dengan tinggi rendahnya larutan kadar TDS di dalam air. Sedangkan pemberian pakan pada ikan hias dapat diberikan secara otomatis sesuai dengan jadwal pemberian pakan yang telah diatur sebelumnya.

Background: Most respiratory disorders are caused by problems or diseases of the respiratory system, including the lungs. Inability of the lungs to expand (elasticity), as well as structural (anatomical) and functional airway obstructions that prevent the creation of breathable airflow, are signs of impaired lung function. Restriction and blockage are two types of lung function problems.Purpose: To analyze the application of the tripod position and pursed lip breathing technique to the increase in oxygen saturation in congested patients in the emergency room at PROF Hospital. Dr. SABOE TONGUE.Methods: Case report, which is a narrative report. The case study in this paper examines the use of a tripod position and pursed lip breathing technique to increase oxygen saturation in shortness of breath patients. Patients with asthma, lung cancer, TB, and COPD constitute the study population. Four patients with asthma, lung cancer, tuberculosis, and COPD were sampled for the study.Results: After the nurse's intervention was carried out, which was related to airway management in the fourth patient, the overall evaluation results were obtained, then the intervention was continued in the patient's treatment room.Conclusion: Based on the description above, people with respiratory problems often experience decreased functional daily activities, decreased concentration, and mood swings. As a result, if the condition of shortness of breath is allowed to continue unnoticed it will reduce oxygen saturation which in turn can cause cyanosis in patients who experience recurrent infections.

The concept of the smart city has emerged as a strategic response to rapid urbanization, increasing population density, and escalating environmental degradation. It is designed to create more efficient urban management through the integration of information and communication technologies, with the primary goal of enhancing public services, optimizing resource use, and improving citizens’ quality of life. One of its most significant promises is its potential to mitigate ecological challenges, particularly in monitoring and reducing air pollution levels. This study aims to analyze the impact of smart city implementation on urban ecology and quality of life, focusing on air quality as a key indicator. A quantitative comparative approach was applied, using both primary data from air quality measurements PM2.5, CO₂, NO₂, and AQI and secondary data from government reports, environmental agencies, and academic publications. The research was conducted in five major Asian cities recognized for adopting smart city initiatives. The results reveal varied outcomes: Tokyo and Kuala Lumpur demonstrated substantial improvements in air quality and livability, while Beijing and New Delhi continued to struggle with severe pollution. Jakarta showed partial progress, though improvements remain limited. These findings indicate that while technology is critical, it alone does not ensure ecological sustainability. Effective governance, public participation, and context-based strategies are equally crucial. This study highlights the need for smart city policies to prioritize ecological resilience and human well-being as central elements of sustainable urban development.
