Abstract

Pengamatan fenomena surface plasmon resonance (SPR) telah berhasil dilakukan pada ZnO nanorods yang ditumbuhkan di atas lapisan tipis emas. Sistem SPR menggunakan konfigurasi Kretschmann termodifikasi dimana permukaan prisma dideposisi dengan lapisan tipis emas dan ZnO nanorods (prisma/Au/ZnO). Penumbuhan ZnO nanorods menggunakan metode hidrotermal dengan dua tahapan, yaitu pelapisan ZnO seed dan penumbuhan rods. Waktu penumbuhan divariasikan selama 5 menit, 2 jam, dan 4 jam, pada suhu 95 °C yang diikuti dengan annealing pada suhu 500 °C selama 1 jam. Struktur ZnO dikarakterisasi dengan X-ray diffraction (XRD), field emission scanning electron microscope - energy dispersive X-ray spectroscopy (FESEM-EDS), serta diamati fenomena SPR melalui grafik attenuated total reflection (ATR). Hasil karakterisasi menunjukkan bahwa ZnO nanorods (2 jam dan 4 jam) memiliki struktur kristal heksagonal dengan distribusi ukuran diameter pada rentang 20 nm – 60 nm. Fenomena SPR hanya teramati pada nanopartikel ZnO (5 menit) pada sudut SPR (θSPR) 58,2°. Fenomena SPR tidak terlihat pada ZnO nanorods (2 jam dan 4 jam) dikarenakan panjang rods melebihi 100 nm.

Abstract

Latar Belakang : Posyandu lansia sangat penting bagi masyarakat khususnya bagi lansia karenamerupakan suatu upaya untuk menyejahterakan lansia dengan cara deteksi dini penyakit agartetap sehat di usia tua serta terhindar dari resiko penyakit yang menyerang pada usia lanjut.Kurangnya pengetahuan wanita usia 45-59 tahun tentang posyandu lansia menyebabkankurangnya kepedulian terhadap kesehatannya, sehingga apabila terjadi permasalahan pada usialanjut mereka hanya menganggap bahwa itu adalah wajar karena sudah umum terjadi pada usialanjut. Tujuan penelitian ini adalah untuk mengetahui gambaran pengetahuan wanita usia 45-59tahun tentang posyandu lansia di Desa Cangkiran Semarang. Metodelogi penelitian yangdigunakan adalah penelitian deskriptif. Populasi dalam penelitian ini adalah semua wanita usia45-59 di Desa Cangkiran Semarang sebanyak 54 orang. Sampel dalam penelitian ini sebanyak 34responden yang diambil dengan teknik accidental sampling. Alat pengumpulan data yangdigunakan adalah kuesioner. Analisis data menggunakan distribusi frekuensi. Hasil penelitiandidapatkan responden berpengetahuan baik sebanyak 12 responden (35,3%), Cukup sebanyak16 responden (47,1%) dan kurang sebanyak 6 responden(17,6%). Karakteristik responden diDesa Cangkiran Semarang berdasarkan umur mayoritas berumur 51-55 tahun sebanyak 25orang (73,5%), berdasarkan pendidikan mayoritas berpendidikan SMP sebanyak 17 orang(50,0%) dan berdasarkan pekerjaan mayoritas bekerja sebanyak 23 orang (67,6%).Kesimpulan pengetahuan wanita usia 45-59 tahun tentang posyandu lansia di Desa CangkiranSemarang mayoritas memiliki pengetahuan cukup yaitu sebanyak 16 responden (47,1%).

Abstract

Introduction Communication is a very important tool in fostering a therapeutic relationship between health workers and patients which can influence the quality of health care services. Therapeutic communication is very important because it can influence the level of patient satisfaction with the health services provided. All behavior and health information provided by midwives must be therapeutic for the patient. Therapeutic communication also develops interpersonal relationships between patients and midwives, where midwives have special skills and must pay attention to every non-verbal interaction and behavior. Good therapeutic communication will lead to patient satisfaction, which ultimately influences patient compliance with the pregnancy check-up schedule. Methode Analytical correlation research, with a total research sample of 25 people. The sampling technique uses simple random sampling. Research data was analyzed using SPSS starting from univariate analysis to describe each research variable, then bivariate analysis to analyze the relationship between the independent variable and the dependent variable using the Spearman rank formula. The results of the Spearman correlation test via SPSS showed that the Spearman correlation coefficient (rs) = 0.320 with a 2 tailed sig value (p) = 0.005 where p < 0.05 so that H1 was accepted, meaning there was a relationship between the variables in this study. Conclusion There is a relationship between effective communication and patient compliance in carrying out pregnancy checks according to schedule.

Abstract

Juice of lime (Citrus aurantifolia) and starfruit (Averrhoa blimbi L) contain citric acid which has the same characteristics as glacial acetic acid in Turk's solution. This study was carried out to determine the potential of them as a substitute for glacial acetic acid in the leukocyte count and compare it with Turk's solution as a standard. We used three variations of concentration, namely 1%, 2% and 3%. The specimen used was venous blood with EDTA anticoagulant which was examined using an improved Neubauer counting chamber. The result showed average number of leukocytes calculated using a solution of star fruit and lime at a concentration of 1% was 6287 cells/mm3 vs 4537 cells/mm3, a concentration of 2% was 3525 cells/mm3 vs 3387 cells/mm3 and at a concentration of 3% was 2775 cells/mm3 vs 3225 cells/mm3. The number of leukocytes in the control (Turk's solution) was 7050 cells/mm3. Starfruit juices with a concentration of 1% gave the results closest to the control. Based on the results of the one-way ANOVA test, the sig value was 0.000 (p<0.05) and the independent t-test showed a value (p>0.05), which means that there was no difference in the number of leukocytes examined with Turk's solution and modified starfruit solution. We concluded, starfruit juices with a concentration of 1% was recommended as a substitute for Turk's solution than lime juice.
