Judul: Karakteristik Penyakit ISPA dan DBD pada Balita Terkait Kondisi Topografi dan Iklim (Kasus: Kabupaten Bogor)
Abstrak: Children under the age of five are a group of children who are susceptible to diseases related to the environmental conditions. The cause of diseases arise from the environmental conditions, including the topography and climate conditions. Research on the characteristics of respiratory infection and dengue fever in children under-five related to the topography and climate conditions is important as an early warning to prevent disease outbreaks. The research was conducted in the study area of several sub districts in Bogor. The analysis includes of determining the topography, climatic conditions and disease categorization, and analysis of the probability. All of which were done to observe the characteristics of the disease occurrence. In general, the characteristic of respiratory infection tends to be higher in sub districts with high topography (mountains), while the characteristic of dengue fever tends to be lower. The characteristic of respiratory infection on rainfall conditions (CH), particularly on high monthly rainfall (CHn> 300 mm), also the increasing of monthly rainfall (CHn-CHn-1 > 60 mm), led to the frequent emergence of respiratory infection in children under-five. Categories of severe dengue fever (IR> 2.525) has the highest chance to occur in two conditions, i.e. the high monthly rainfall (CHn> 300 mm) and the increasing of monthly rainfall (CHn-CHn-1 > 60 mm), or on medium monthly rainfall conditions (162-300 mm) and the decreasing of monthly rainfall (CHn-CHn-1 <60 mm).

Judul: Angka Kejadian Infeksi Saluran Pernapasan Akut (Pneumonia) pada Balita Akibat Pengaruh Iklim dan Kualitas Udara di Kota Bogor
Abstrak: Pneumonia merupakan salah satu penyakit infeksi saluran pernapasan yang disebabkan oleh virus, bakteri, dan mikroorganisme lainnya sebagai faktor utama, dan faktor lingkungan seperti iklim dan kualitas udara sebagai faktor pendorong. Kota Bogor memiliki kepadatan lalu lintas dan curah hujan yang tinggi, sehingga berpotensi terpapar pencemar udara dan kelembaban yang tinggi. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang dapat mempengaruhi angka kejadian Pneumonia pada balita di Kota Bogor. Hubungan antara angka kejadian Pneumonia dengan faktor iklim dan particulate matter (PM) dianalisis menggunakan analisis korelasi, analisis komponen utama (PCA), dan grafik. Curah hujan dan kelembaban udara yang tinggi saat musim hujan dapat mengurangi konsentrasi PM di udara bebas, tetapi meningkatkan peluang berkembangnya mikroorganisme di dalam ruangan, sehingga kejadian Pneumonia pada balita meningkat, terutama pada peralihan musim hujan ke kemarau. Konsentrasi PM yang tinggi di udara bebas saat musim kemarau juga dapat meningkatkan kejadian Pneumonia. Hasil PCA menunjukkan bahwa kejadian Pneumonia di Kota Bogor didominasi oleh kondisi lembab. Kejadian Pneumonia di Kota Bogor tinggi saat kelembaban udara tinggi dan konsentrasi PM2.5 terukur rendah. Pengaruh PM2.5 terukur terhadap Pneumonia lebih dominan terjadi saat pergantian musim dari musim kemarau ke musim hujan yaitu pada bulan SON.

Abstrak: The increasingly public awareness about food safety on used frying oil and the increasingly serious environmental destruction have made biodiesel from used frying oil to become an alternative fuel for replacing diesel fuel position in most conventional diesel engines. Transesterification of used frying oil with methanol, in the presence of 1% sodium , hydroxide catalyst (base on weight of oil) was applied in this work.
