One of the causes of the high infant mortality rate in Indonesia is the lack of health support facilities in remote areas, including incubators, to keep the baby's body warm at a specific temperature. This research develops a model and prototype of a mobile incubator to carry and maintain the baby's temperature during emergencies to get further treatment to hospitals that have better facilities than incomplete health clinic facilities. The mobile incubator prototype uses a PID controller system with the optimum gain value Kp 1.501, Ki 0.016, and Kd -1,319 from the results of modeling and tuning in Matlab. The results of the bode plot analysis show that system stability was achieved with a gain margin of 109 dB. The incubator's operational mobility can last up to 59.6 minutes with two 12 V, 5 Ah batteries.

Background : Most human activities cannot be separated from the use of computers. Long-term and uncontrolled use of computers can lead to Computer Vision Syndrome (CVS). According to the Ministry of Health of the Republic of Indonesia (KEMENKES) CVS can be handled with ergonomics use of computers resultantly reducing the impact of computer exposure. Education on ergonomics use of computer and PERMATA-KU exercise is expected to improve CVS scores.Research Purpose : Proving the effect of PERMATA-KU exercises toward CVS score improvementMethod : Research subjects are divided into treatment group and control group, each group consists of 15 people. The treatment group received education about the ergonomics use of computer and PERMATA-KU exercises while the control group received education on the ergonomics use of computers. The measurement’s instrument is the CVS questionnaire. The dependent variable of the study was the CVS score and the independent variable of the study was the type of treatment. Statistical test with Wilcoxon, paired t test, unpaired t test, Mann whitney and chi square. Meaning value p <0.05.Result : There was a significant difference in CVS scores before and after the intervention in the treatment group (p = 0.001) and the control group (p = 0.006). There was a significant difference in delta CVS scores between the treatment group and the control group (p=0,008). There was a significant difference in CVS scores after the intervention in the treatment group and the control group (p=0,017). There was no significant difference in the incidence of CVS after the intervention between the treatment group and the control group (p = 0.259).Conclusion : There is an effect of "PERMATA-KU" exercise on the improvement of CVS scores.

ABSTRAK Latar Belakang: Computer Vision Syndrome (CVS) merupakan kumpulan masalah pada mata dan penglihatan akibat dari penggunaan komputer, telepon seluler, tablet, dan e-reader yang berkepanjangan. Dry eye (mata kering) merupakan salah satu gejala yang biasa muncul pada CVS. Pada penelitian ini dilakukan senam ‘PERMATA-KU’ (Pelihara Mata–Kendorkan Bahu) sebagai senam tambahan untuk mengurangi gejala dry eye pada CVS. Tujuan: Membuktikan adanya perbaikan skor OSDI (Ocular Surface Disease Index)  sebelum dan setelah senam “PERMATA-KU” pada CVS. Metode: Jenis penelitian adalah penelitian ekperimen kuasi dengan Pre-Post with Control Design. Subjek penelitian adalah mahasiswa Fakultas Kedokteran UNDIP yang mengalami CVS dan memenuhi kriteria inklusi dan eksklusi yang  dikelompokkan menjadi kelompok perlakuan dan kelompok kontrol secara acak. Kelompok perlakuan diberikan intervensi edukasi ergonomis penggunaan komputer dan senam PERMATA-KU selama 14 hari. Kelompok kontrol diberikan intervensi edukasi ergonomis penggunaan komputer. Skor OSDI diukur sebelum dan setelah intervensi menggunakan kuesioner Ocular Surface Disease Index. Hasil: Subjek penelitian berjumlah 32 orang dengan 16 orang pada kelompok perlakuan dan 16 orang pada kelompok kontrol. Satu orang pada kelompok kontrol dan satu orang pada kelompok perlakuan drop out karena tidak dapat menyelesaikan prosedur penelitian sehingga hanya 30 subjek penelitian yang dianalisis. Skor OSDI setelah intervensi pada kelompok perlakuan mengalami penurunan signifikan (p<0,05). Skor OSDI setelah intervensi pada kelompok perlakuan lebih baik daripada kelompok kontrol (p<0,05). Perbaikan skor OSDI pada kelompok perlakuan lebih baik dibandingkan dengan kelompok kontrol tetapi tidak signifikan (p=0,595). Kesimpulan: Senam PERMATA-KU yang dilakukan selama 14 hari dapat memperbaiki skor OSDI pada Compter Vision Syndrome.   Kata Kunci: Compter Vision Syndrome (CVS), Ocular Surface Disease Index (OSDI), dry eye, Senam PERMATA-KU

Stroke is one cause of the most deaths, in which one way of handling stroke can be done with hydrotherapy. Hydrotherapy is a therapy that is done in the therapeutic pool which is filled with warm water in temperature 31°-34° C. When in the warm water, body burden becomes lighter, so the stroke patients with impaired movement of the body can train the nerves and muscles in order to restore the function of these organs. However, the warm water that is used for the therapy is produced by the heater that requires much electrical energy. This research discussed how to use solar energy to produce hot water using Indirect Evacuated Tube Solar Water Heater systems and make the control system for controlling the mixing process between the hot and cold water by using the Fuzzy Logic Control of the Mamdani method. Therapeutic pool system will be modeled using Simulink. Modeling the mixing process is made on the basis of mass balance and energy balance equations. Then the system will be simulated with interrupted condition and gets set value changes in a particular time. The FLC is successfully reached and maintained steady to a set value. The results will be compared to the performance of the one with Proportional Integral Derivative controller.
