Solar energy is free from noise and environmental pollution. It could be used to replace non-renewable sources such as fossil fuels, which are in limited supply and have negative environmental impacts. The first generation of solar cells was made from crystalline silicon. They were relatively efficient, however very expensive because they require a lot of energy to purify the silicon. Nowadays, the production of solar cells has been improved since the first generation (thin-film solar cells, dye-sensitized solar cells, perovskite solar cells, and organic solar cells). In this work, the development of solar cells was discussed. The advantages, limitations, challenges, and future trends of these solar cells were also reported. Lastly, this article emphasized the various practices to promote solar energy and highlighted the power conversion efficiency of the fabricated devices.

AbstrakPenyakit tidak menular (PTM) merupakan penyakit yang bersifat kronis dan tidak ditularkan dari orang ke orang. Prevalensi PTM terus mengalami peningkatan seiring dengan perubahan pola hidup masyarakat kearah yang kurang seimbang. Faktor risiko PTM di Provinsi NTB antara lain adalah hipertensi, obesitas dan diabetes. Kurangnya pengetahuaan dan kesadaran terhadap bahaya PTM menyebabkan deteksi dini berbasis pelayanan kesehatan kurang efektif. Hal ini juga disebabkan oleh enggannya masyarakat memeriksakan diri selama belum merasa sakit. Penanggulangan faktor resiko PTM dan pencegahan berbasis masyarakat menjadi salah satu solusi yang dapat dilakukan untuk menekan resiko atau angka kematian akibat PTM. Kegiatan ini bertujuan untuk meningkatkan kesadaran masyarakat terhadap pentingnya tes kesehatan secara berkala sebagai upaya deteksi dini PTM. Kegiatan ini kemudian dilakukan dengan dua metode, yaitu diskusi dan praktik langsung untuk memeriksa kesehatan peserta. Secara keseluruhan, hasil pemeriksaan kesehatan cukup baik dengan rata-ata hasil pemeriksaan normal. Hanya saja dari kegiatan ini dijumpai dua peserta dengan hasil gula darah diatas 300 mg/dL. Dengan adanya kegiatan semacam ini, masyarakat menjadi semakin sadar akan pentingnya tes kesehatan secara berkala untuk deteksi dini PTM. �Kata Kunci: PTM, Pemeriksaan Kesehatan, Gula Darah, Asam Urat.Abstract�Non-communicable Diseases (NCD) are a chronic and not transmitted from preson to person. The prevalence of NCDs seems to be increased along with life style change into unbalance style. Risk factors of PTM in NTB are hypertension, obesity and diabetes. Less of knowledge and awareness to NCD�s risk lead early detection and prevention based on health facilities to be less effective. This is also caused by the reluctance of people to check themselves before they feel sick. Management of PTM risk factors and community-based prevention is a solution that can be done to reduce the risk or mortality rate due to PTM. This community service activities aims to increase people awareness due to the importance of periodicly doing medical check-up in order to screen NCDs. We conduct this activity in two methods, discussion and practically check people health status. Overall, the result was fine. But, two of the participant have blood glucose more than 300 mg/dL. By this community services, peoples become aware about the importance of medical check-up in early detection of NCD.��Keywords : NCD; Medical Check Up; Blood Glucose; Uric Acid.

Abstrak: Darah merupakan salah satu komponen paling penting yang ada dalam tubuh, mengingat fungsinya  sebagai alat transportasi. Kekurangan darah di dalam tubuh dapat memacu sejumlah penyakit  dimulai dari anemia, hipotensi, serangan jantung, dan beberapa penyakit lainnya. Beberapa kasus lain seperti kecelakaan, luka bakar dan proses persalinan juga memerlukan tranfusi darah akibat tingginya kemungkinan pendarahan. Terdapat dua jenis penggolongan darah yang paling penting adalah penggolongan A-B-O dan Rhesus (faktor Rh). Transfusi darah dari golongan yang tidak kompatibel dapat menyebabkan reaksi transfusi imunologis yang berakibat anemia hemolisis, gagal ginjal, syok, dan kematian. Banyak diantara kita belum mengetahui jenis golongan darah yang kita miliki. Kasus ini menjadi sangat krusial ketika individu tersebut mengalami musibah, seperti kecelakaan yang mengakibatkan darah banyak keluar. Tindakan penanganan pasien menjadi terlambat, karena individu ini belum mengetahui jenis golongan darah yang ia miliki. Berdasarkan hasil observasi dengan siswa, Kepala Sekolah dan guru-guru Madrasah Aliyah NW Bagik Polak, dapat disimpulkan bahwa sebagian besar siswa di sekolah ini belum mengetahui golongan darah yang ia miliki. Kejadian ini  menjadi dasar kami untuk melakukan pengabdian kepada masyarakaat dalam hal ini siswa untuk mengecek golongan darah yang mereka miliki.Abstract:  Blood is one of the most important components in the body, given its function as a means of transportation. Blood deficiency in the body can spur some diseases starting from anemia, hypotension, heart attack, and some other diseases. Some other cases such as accidents, burns, and childbirth also require blood transfusions due to the high likelihood of bleeding. There are two most important types of blood type which are the A-B-O and Rhesus (RH) classification. Incompatible blood transfusions can cause immunological transfusion reactions that result in hemolysis anemia, renal failure, shock, and death. Many of us do not know the type of blood group we have. This case became very crucial when the individual suffered a calamity, such as accidents that caused many types of blood to come out. The patient's treatment was delayed, as the individual did not know what type of blood he had. Based on the results of the observation with the students, the principal, and teachers of Madrasah Aliyah NW Bagik Polak, it can be concluded that most students in this school do not know the blood type he has. This incident is the basis for our devotion to the community in this case students to check the blood group they have.
