Abstract

Dengue Hemorrhagic Fever (DHF) caused by four virus serotypes is a disease with A. aegyti and A. albopictus mosquitoes as vectors. DHF is a recurrent and high burdened disease in Indonesia. The purpose of this study is to analyze the spreading of DHF risk in Central Jakarta based on environmental factors. The cases number data year 2000-2009 was obtained from Center of Infectious Disease Research, National Institute of Health in Research and Development. Survey was performed in 38 subdistricts using random and purposive methods. Risk indicators were used in environmental data collection. The results of this study showed similar cyclical pattern each year.  March until May had a high DHF incident, while November until January had a relatively low DHF incident. In general, Central Jakarta had a medium risk potential of DHF spreading. Spearman rank analysis on adjacent areas gave various values. Subdistricts of Senen and Kemayoran had a low correlation, while subdistricts of Johar Baru and Cempaka Putih had the highest correlation among other subdistricts showing that there were vector migrations between these two subdistricts. Finally, the data obtained should be useful for minimalizing the risk of DHF spreading especially by vector control management.

Abstract

Abstrak - Anemia merupakan masalah kesehatan yang penting di seluruh dunia. Sekitar 51% ibu hamil menderita anemia dua kali lipat dari pada wanita tidak hamil. Penyebab anemia gizi besi terutama dikarenakan penyerapan zat besi dari makanan atau suplemen. Sari buah kurma (Phoenix dactylifera) sering disebut sebagai makanan yang dapat meningkatkan kadar hemoglobin karena kandungan zat besi yang tinggi. Tujuan penelitian ini adalah mengetahui pengaruh pemberian sari kurma terhadap peningkatan kadar hemoglobin ibu hamil dengan anemia. Metode penelitian menggunakan studi intervensi dengan metode one group pretest – posttest. Populasi dalam penelitian ini adalah ibu hamil trimester II dengan anemia. Besar sampel adalah 11 responden. Uji statistik yang digunakan adalah uji Wilcoxon dengan tingkat kepercayaan 95%. Hasil penelitian menunjukkan rata-rata kadar hemoglobin sebelum pemberian sari kurma sebesar 9,6 gr/dL, sedangkan sesudah pemberian sari kurma selama 10 hari rata-rata sebesar 10,6 gr/dL. Ada pengaruh yang signifikan (p value 0,004 < 0,05) pemberian sari kurma dengan kadar hemoglobin ibu hamil dengan anemia. Namun demikian hasil pengujian laboratorium diketahui kadar zat besi pada sari kurma rendah. Penelitian menyimpulkan bahwa sari kurma dapat meningkatkan kadar hemoglobin pada ibu hamil dan dijadikan suplemen meningkatkan kadar hemoglobin. Sari kurma bukan merupakan makanan sumber zat besi.Abstract - Anemia is an important health problem worldwide with 51% of pregnant women being doubly anemic compared with nonpregnant women.

Abstract

Abstrak - Kondisi pemukiman masyarakat sekitar DAS Ciliwung yang terlihat cukup  padat menjadi salah satu faktor penyebab pencemaran air sumur. Selain itu tidak teraturnya  jarak antara rumah dengan sungai ataupun jarak antara satu rumah dengan rumah lainya juga berdampak pada kelestarian sungai.  Ketentuan yang ideal jarak pemukiman warga dengan tepi sungai diatur dalam Peraturan Pemeritah (PP) No 38 Pasal 9 Tahun 2011 yaitu paling sedikit berjarak 30 m dari tepi kiri dan kanan palung sungai sepanjang alur sungai, dalam hal kedalaman sungai lebih dari 20 m. Dari ketentuan  di atas dapat diketahui kemungkinan adanya kontaminasi bakteri Coliform pada air sumur yang bersumber dari sumur di sekitar DAS Ciliwung. Oleh karena itu perlu dilakukan pengujian kualitas air sumur untuk mengetahui kelayakan dan keamanan air untuk dikonsumsi masyarakat. Penelitian ini bertujuan untuk menguji keberadaan Coliform pada air sumur di sekitar DAS Ciliwung wilayah Pejaten Timur hingga Kalibata. Metode yang dilakukan pada penelitian ini adalah penentuan jumlah koloni berdasarkan Total Plate Account (TPC) dari sumber sampel air sumur tanah warga. Berdasarkan hasil pengujian didapatkan bahwa air sumur positif mengandung bakteri Coliform. Jumlah Coliform tertinggi ditemukan di wilayah Pejaten Timur dan Condet sebanyak 9.4 x 104 cfu/ml dan 8.9 x 104 cfu/ml.  Sementara itu jarak sumur terdekat dengan sungai  yaitu < 10 m juga terdapat di wilayah Pejaten Timur dan CondetKata Kunci – Ciliwung, Air Tanah, ColiformAbstract - The crowd of people’s residentials around Ciliwung river were known to be one of the factors that caused groundwater pollution. Beside that, the lay out of houses were also participated to the river sustainability. People built their houses without any environment considerations. They built houses near to the river. According to the local government rules Peraturan Pemeritah (PP) No 38 Pasal 9 Tahun 2011, people could built houses approximately 30 m to the river if it had 20 m in depth. Based on river pollution data, we assumed that the groundwaters probably contaminated by Coliform bacteria. This hyphotese could be analyzed using several tests in order to examine the groundwater quality. If the water quality data could be gained, so it should be informed about the appropriateness to consume their groundwater. The research was aim to analyze the Coliform that collected from groundwater around Pejaten Timur to Kalibata. The metholodology of research were using Total Plate Count (TPC) in order to quantify colony number. The microbes were isolated from 51 groundwaters around areas. Based on results, all samples from groundwaters were positively contaminated by Coliform founded in Pejaten Timur and Condet. This finding indicated that contamination level in groundwater could affect people’s integument and digestive system health.Keywords - Ciliwung, Groundwater, Coliform
