Abstract

Konsistensi kepatuhan terhadap pengobatan merupakan faktor kunci dalam mengontrol tekanan darah. Penelitian ini bertujuan untuk mengetahui hubungan usia, jenis kelamin, pendidikan, pekerjaan, jenis terapi, durasi terapi, derajat hipertensi dan komorbid dengan kepatuhan pasien dalam menggunakan obat. Desain studi pada penelitian ini yaitu cross sectional korelasional analitik di Puskesmas Sosial Palembang. Data penelitian diperoleh dari data primer menggunakan kuesioner MMAS-8 dan data sekunder dari rekam medis. Uji hubungan menggunakan chi square dan parameter kekuatan hubungan dinilai dengan odds ratio (OR). Responden sebanyak 66 orang berada pada tingkat kepatuhan tinggi 57,6% dan tingkat kepatuhan rendah – sedang 42,4%. Terdapat hubungan antara usia (p=021), pendidikan (p=0,034), durasi terapi (p=0,017) dan komorbid (p=0,036). Nilai odds ratio komorbid (OR=6,00), usia (OR=5,43), pendidikan (OR=2,14) dan durasi terapi (OR=0,26). Adanya komorbid, usia yang lebih tua dan pendidikan yang lebih tinggi merupakan faktor yang mendukung kepatuhan terhadap pengobatan hipertensi. Hasil penelitian diharapkan dapat memberikan masukan dalam menyusun strategi untuk meningkatkan kepatuhan pasien.

Abstract

Farming is one sector that has an important role in building Indonesia's economic growth, especially for daily food. Farm production is facing challenges, include the low production yield, traditional management, and problems related to animal health. Infectious Bovine Rhinotracheitis (IBR) and Malignant Catarrhal Fever (MCF) are diseases caused by Herpesviridae. These are high mortality rate disease cause huge economic loss. Farms located nearby deer captivity increases the risk of deer to be infected by the same diseases. Surveillance is needed to discover the number of infected animals and their effect on the environment. Herpesviridae identification in surveillance was done through an accurate method, e.g. a molecular method. This research is done by Lampung Disease Investigation Center and funded by the Food Agriculture Organization (FAO). Herpesviridae identification was done in three steps, DNA isolation, Polymerase Chain Reaction (PCR), electrophoresis, and visualization.

Abstract

The Southern Waters of Java included in 573 WPP has high fishing activity, which the most important commodity is Tuna. The number of Tuna catch are fluctuated which influenced by oceanography factors in the waters. Some of the factors that affect the catch are sea surface temperature (SST) and chlorophyll-a, so this study aimed to determine the distribution, fluctuations in SST and chlorophyll-a, and its relationship to the Tuna catch. SST and chlorophyll-a data were downloaded from NASA, and Tuna catch data in 2017 was collected from Cilacap Fishing Port. The relationship between SST and chlorophyll-a with the catch was analyzed with cross correlation analysis. Distribution of SST and chlorophyll-a was higher in the east part and coastal areas compared to the western and offshore parts. SST and chlorophyll-a fluctuations are inversely proportional but have a very close relationship. SST in the western season and transition 1 an increase then a decline in the east season and transition II, while chlorophyll-a in the western season and transition I is lower than in the east season and transition II. The highest correlation between SST and catch in the time lag -3, while chlorophyll-a in the lag time -4.
