The emergence of Corona Virus Disease 19 (Covid-19) required a new method to control its spread. During this time, controlling COVID-19 was carried out by implementation of a sterilization chamber using a liquid-based disinfectant. However, the use of liquid-based disinfectants has been evaluated to be less effective because it allows disrupting the respiratory tract. Therefore, this work presents a negative pressure sterilization chamber using Ozone and UV-C lamp. Ozone has been recommended by the Indonesian Institute of Sciences (LIPI) as a substitute for liquid-based disinfectants. In addition, to maximize performance, the chambers are added with UV-C lamps. The negative pressure sterilization chamber with Ozone and ultraviolet lamps was successfully created with the main parts of the cubicle chamber, an Ozone generator, at least one ultraviolet lamp, exhaust fan, switch, and a timer. The negative pressure sterilization chamber with Ozone and ultraviolet lamps according to this work, where the Ozone supply from the Ozone generator is made automatically to the door opening and closing. The duration of the Ozone supply was regulated by a timer. Then, the ultraviolet lamp can be activated together with Ozone or independently. With the implementation of this sterilization chamber, the spread of the Covid-19 virus is expected to be suppressed in a safer way than using liquid-based disinfectants.

Menua merupakan suatu proses natural, penuaan akan terjadi pada semua sistem tubuh manusia dan tidak semua sistem akan mengalami kemunduran pada waktu yang sama. Meskipun proses menjadi tua merupakann gambaran yang univeral, namun tidak seorang pun mengetahui dengan pasti penyebab penuaan atau mengapa manusia menjadi tua pada usia yang berbeda – beda. Kondisi ini ditandai dengan terjadinya banyak penurunan baik secara fisik, maupun psikis. Terjadinya penurunan ini akan membuat lansia melakukan koping terhadap penurunan yang terjadi pada diri mereka. Tujuan penelitian ini untuk mengetahui hubungan antara status gizi dengan penyakit degeneratif kronik pada lansia di Puskesmas Jogonalan I. Penelitian ini menggunakan desain kuantitatif korelasi dengan pendekatan Cross Sectional. Populasi pada penelitian ini adalah lansia yang memeriksakan kesehatannya di Puskesmas Jogonalan I.
