The infectious of ectoparasites has a harmful impact to mangrove crabs. This study aimed to know ectoparasites that infected mangrove crabs and determine the prevalence of ectoparasites that attack mud crabs. 10 crabs / pond were randomly taken from two pounds. Identification of Crab was conducted in Laboratory of Water Resource Management, Faculty of Agriculture, University of Sumatera Utara. Parasite were observed in walking foot, swimming foot, claws, carapaks and gill of the crab. The result showed that 4 ectoparasites i.e Vorticella, Epistylis, Zoothamnium and Octolasmis were found from crabs of two ponds. Vorticella, Epistylis, and Octolasmis of Bagan Percut Ujung showed a relative high prevalence of 50%, while Octolasmis of Tangkahan Lagan Showed high Prevalence of 30%.Keywords: Ectoparasit, Mangrove Crab, Prevalence

Silvofishery based mangrove ecosystem based resource management has been alreadywidely known and practiced, both at home and abroad. However, until now it’s difficultto find silvofishery application with correct and proper principles, in terms of bioengineering, ecological and institutional. The researched was conducted on March2012. The aims of this study were (1) assess the ecological status, (2) assess fishaquaculture bioengineering, (3) economic and financial analysis for the silvofisheryapplication, and (4) determine the pattern of silvofishery management in RPH TegalTangkil.Collected data were related to ecological, economic, social and institutionalaspect, which related to silvofishery management in RPH Tegal-Tangkil. The researchshowed that, mangroves contribute significantly to the daily shrimp by product. Waterquality conditions currently were still suitable for fish aquaculture activities. Althoughthere were discovered heavy metals content in this area, there for it is necessary toimprove water quality by develop reservoir system. In terms of bioengineering, fishermanwere still culture fish by traditionally technique and not done with correct and properprinciples. Economically silvofishery system was still able to develop for increasefishermans incomes. If silvofisheries were applied properly, it can increase fishermanincome up to 509.60%. However, silvofishery management was still deficient; It is seenfrom the difference between the ideal and reality. Institutional improvement minawanamanagement system at least focus on the improvement of the organization and rules ofthe game.

Differences in drugs consumption time may affect its absorption and metabolism in the bodywhich could lead to differences in its efficacy. For hypertension patients, one of the mostfrequently used drugs for lowering blood is captopril. However, information regarding theinfluence of consumption time on captopril efficacy was limited. Therefore, this study wasconducted to compare the efficacy of captopril in lowering blood pressure when administeredbefore and after meal. This was an experimental study with two treatment groups,conducted at Dr. Soedarso General Hospital, Pontianak, Indonesia, during April-June 2015.Statistical analysis was performed using Mann-Whitney, Exact-Fisher, and T-test. We foundout that the reduction of systolic blood pressure in group who consumed captopril beforeand after meal was 30 mmHg and 25 mmHg, respectively (p<0.05). The similar reduction indiastolic bloos pressure was observed in both groups (10 mmHg, p>0.05). In conclusion, itis recommended to take captopril on an empty stomach since it showed better efficacy whenadministered before meal compared to after meal consumption.Keywords: hypertension, captopril, absorption

Drug related problems (DRPs) are problems encountered often in the treatment of patients and can affect the decline of quality of life but increase disease morbidity and mortality on the other hand. From a review of 10 journals, it was found that untreated indication, adverse drug reaction, non-compliance/non-adherence, drug choice problem, dosing problem, drugs interaction, drug without indication, and drug use problem were the most common DRP experienced by type 2 diabetes mellitus patients. Pharmacists can effectively intervene in DRP through identification and prevention and physicians accept and act on these interventions. Pharmacists in their intervention on DRPs play an influential role at the prescriber level. Pharmacist intervention can also take place at both patient and drug levels. Pharmacist intervention is also capable of controlling the parameters of an objective examination to be better (lipids, blood pressure, blood sugar, etc.). Therefore, collaboration between pharmacists and other health workers needs to be pursued because it can affect the success in handling DRPs.

Komplikasi Gagal Ginjal Kronik (GGK) yang sering terjadi dan biasanya terjadi paling awal dari komplikasi yang lain adalah anemia. Defisiensi eritropoetin merupakan salah satu faktor yang berkaitan dengan anemia pada GGK. Penurunan fungsi ginjal yang progesif dan irreversible menyebabkan pasien GGK harus melakukan hemodialisa. Hal tersebut dapat mempengaruhi kualitas hidup pasien mortalitas dan morbiditas. Tujuan penelitian ini adalah untuk mengetahui pengaruh anemia tanpa terapi eritropoetin terhadap kualitas hidup pasien gagal ginjal kronik dengan terapi hemodialisa di RSBSA Bandung dan RSD Cimahi yang dilaksanakan pada bulan Mei sampai Juni 2019. Desain penelitian ini menggunakan metode penelitian analisa cross sectional dengan menggunakan data primer dan teknik consecutive sampling. Hasil penelitian ini di dapat jumlah sampel 50 orang yang memenunuhi kriteria inklusi. Kualitas hidup diukur dengan menggunakan kuisioner EQ5D5L yang dilakukan pada saat pasien menjalani terapi hemodialisa. Nilai utilitas terapi eritropoetin 0,65±0,29 dan tanpa terapi eritropoetin mengalami penurunan menjadi 0,63±0,27. Sedangkan skor rata-rata EQ5D Visual Analog Scale (VAS) terapi eritropoetin adalah 62,29±18,88 dan tanpa terapi eritropoetin 69,42±14,65. Hasil penelitian ini menunjukkan bahwa perubahan nilai utilitas dan skor EQ5D VAS pasien hemodialisa terapi eritropoetin dan tanpa terapi eritopoetin tidak menunjukkan perbedaan yang bermakna secara signifikan (p<0,05).

Sungai Mombang banyak dimanfaatkan masyarakat untuk kegiatan sehari-hari. Kegiatan tersebut tentunya memberikan dampak dan tekanan terhadap perairan sungai sehingga dapat menjadi ancaman serius bagi kelestarian dan keanekaragaman hayati ikan di perairan. Penelitian ini bertujuan untuk mengganbarkan keragaman ikan di Sungai Mombang, Kecamatan Batangtoru, Kabupaten Tapanuli Selatan. Titik lokasi pengamatan terdiir dari 4 lokasi. Ikan ditangkap dengan alat backpack electrofishing dengan kekuatan arus lisitrik sebesar 9 ampere. Kondisi habitat yang di surveiyaitu: suhu, DO, BOD, nitrat, fosfat, arus, kedalaman, dan kecerahan. Hasil penelitian di Sungai Mombang Kecamatan Batang Toru Kabupaten Tapanuli Selatan didapatkan 16 spesies ikan, yang termasuk ke dalam 6 ordo, 8 famili. Ikan Jurung dan Ikan Sidat merupakan ikan ekonomis yang terdapat di Sungai Mombang. Ikan-ikan yang ditemukan di Sungai Mombang merupakan ikan asli, kecuali Ikan Nila (Oreochromis niloticus). Diversitas ikan di Sungai Mombang tergolong tinggi dibandingkan dengan sungai-sungai kecil lainnya di Sumatera. Secara umum kondisi habitat ikan di Sungai Mombang termasuk baik dan layak bagi kehidupan ikan.
