Abstract

Dye-sensitized solar cell (DSSC) is one of the photochemical electrical cells consisting of a photoelectrode, dye, electrolyte, and counter electrode. The manufacture of prototype Dye-sensitized solar cell (DSSC) utilizes carotene from the dye extract of mangosteen peel pigment (Garnicia mangostana). This study aims to create a Dye-sensitized solar cell (DSSC) and know the efficiency it produces. This Dye-sensitized solar cell (DSSC) consists of a pair of FTO (Flour-doped in oxide) glass intercepts facing each other. The glass acts as an electrode and counter electrode and separated by a redox electrolyte (I- / I3-), arranged to flank each other to form a wafer. In the electrode, is deposited a porous nanocrystalline TiO2 layer, as well as dye extract of mangosteen peel pigment (Garnicia mangostana). While on the counter electrode coated with a layer of platinum.

Abstract

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.
