<em><span>Ventilators are one of the medical devices that are needed as a breathing apparatus for COVID-19 patients who have respiratory problems. One of the low-cost ventilators currently being developed by several domestic institutions is the ambu bag-based ventilator. The point is an air bag (bag) that is pressed by two carefully controlled automatic clamps, so that it can reach all, while taking into account portability, aesthetics and ease of manufacture. Therefore, the Bag Valve Mask (BVM) or ambu bag is an emergency option to replace the function of the ventilator. This study aims to make an ambu bag that can be applied as a portable mechanical ventilator. Thus, the ambu bag which was originally used manually can be used automatically like a ventilator machine in general. In determining the type of mechanical arm pressure, several parameters such as minute volume, respiratory rate, and tidal volume are used. As recommended by the American Heart Association (AHA) that the tolerance limit for the RR value is +/-10 BPM, it can be said that the automatic BVM as a result of this study can be used with or without a reservoir as needed or with the addition of oxygen</span></em>

Peranan merek sangat penting terutama dalam persaingan usaha yang sehat oleh karena itu perlindungan terhadap merek diperlukan. Di Indonesia, perlindungan merek akan diperoleh setelah merek didaftarkan. Namun perlindungan hukum terhadap merek terdaftar bukan merupakan jaminan, adakalanya apabila terdapat cukup alasan pendaftaran merek dapat dihapus atau dibatalkan. Salah satu kasus penghapusan merek dari Daftar Umum Merek adalah sengketa merek IKEA yang diputus oleh Mahkamah Agung dengan Putusan No. 264K/Pdt.Sus-HKI/2015. Gugatan penghapusan merek IKEA milik INTER IKEA dilakukan oleh perusahaan asal Surabaya PT. Ratania Khatulistiwa. Alasannya bahwa merek IKEA untuk kelas barang 20 dan 21 tidak digunakan selama 3 tahun berturut-turut dalam perdagangan barang dan/atau jasa sejak tanggal pendaftarannya. Penelitian ini merupakan penelitian hukum sehingga berproses pada kajian norma dalam hal ini norma dalam hukum merek secara khusus merek terkenal dengan mengkaji tentang penghapusan merek. Dari penelitian menunjukkan bahwa sekalipun merek terkenal dihapuskan dari Daftar Umum Merek, tetapi perlindungan merek terkenal tidak hilang.  
Trademark protection in Indonesia will be obtained after the trademark is registered. However, in some circumstances, legal protection for registered trademarks could be deleted or canceled, such as in the IKEA case. IKEA is a registered trademark base on the Indonesian General Register of Marks. Then, PT. Ratania Equator brought a lawsuit for the removal of IKEA from the registered trademark from the General Register of Marks. The reason is that IKEA, as a trademark for goods in classes 20 and 21, has not been used for 3 consecutive years in the trade in goods and/or services. This article argues that even though a well-known trademark is removed from the General Register of Trademarks, the protection of the well-known trademark has remained.

<p>Air merupakan kebutuhan utama mahluk hidup. Kegunaan air yang bersifat universal atau menyeluruh dari setiap aspek kehidupan menjadi semakin berharga baik secara kuantitas maupun kualitas. Pengelolaan sumber daya air untuk penyelenggaraan irigasi berkaitan dengan keberlangsungan sistem irigasi dalam rangka pemenuhan kebutuhan pangan yang terus meningkat.

Abstract Catfish is one of the important strategic commodities in Indonesia which is widely cultivated. Catfish needs continue to increase along with the increasing demand for catfish as foodstuffs such as the need for many lamongan stalls. However, efforts to increase production and development of catfish farming have several obstacles that can reduce production by 50% due to certain diseases. This situation is certainly very detrimental to the catfish in particular and the wider community in general. However, farmers have very low knowledge about the technical maintenance of catfish plants. This situation resulted in farmers being highly dependent on the control of a limited number of plant pests. To overcome this problem, a website-based application was made. To optimize computational resources on mobile devices, we need a Cased Base reasoning method that consists of frame based and rule based representation with rules or rules that are used to determine whether catfish plants contract certain diseases, which types of diseases can be detected in the process this research includes bacterial pustular disease, interchnose disease, mosaic virus disease, collapsing disease, rust disease and blight disease. then analyzed which cased base reasoning is the most optimal. This can be done with a scenario comparing some of the cased base reasoning from the level of accuracy at 87.5%.
