Judul: Analisis Perubahan Pola dan Perilaku Konsumsi Air Rumah Tangga di Kota Bogor (Studi Kasus: Rumah Tangga Pelanggan PDAM di Kelor Raya)
Abstrak: Pembangunan dan penyediaan air dilakukan oleh pemerintah untuk memastikan masyarakat mendapatkan akses air bersih serta sanitasi yang layak dan berkelanjutan. Kota Bogor merupakan kota terbesar dalam penggunaan air bersih di Jawa Barat dimana setiap tahunnya penyaluran air bersih ke masyarakat mengalami peningkatan. Tujuan dari penelitian ini adalah 1) Menganalisis persepsi serta perilaku masyarakat terhadap konsumsi air berkelanjutan, 2) Mengidentifikasi perubahan pola konsumsi air sebelum dan pada masa pandemi dan faktor-faktor yang memengaruhi, 3) Menganalisis alternatif strategi pendukung konsumsi air berkelanjutan. Penelitian ini menggunakan analisis skala likert, analisis regresi linear berganda, analisis deskriptif kuantitatif, dan analisis weighted sum model. Hasil penelitian menunjukkan bahwa masyarakat sangat setuju dengan konsumsi air berkelanjutan dan sebagian besar perilaku masyarakat dalam penggunaan air menunjukkan konsumsi air berkelanjutan. Konsumsi air masyarakat mengalami perubahan yaitu terjadi peningkatan penggunaan air untuk kegiatan yang membutuhkan air pada saat pandemi yang berdampak pada meningkatnya rata-rata biaya tagihan air per rumah tangga yaitu sebesar Rp.19.950 per bulannya. Tingkat pendidikan, pendapatan rumah tangga, dan harga air memengaruhi jumlah konsumsi air masyarakat. Strategi yang dapat dilakukan untuk mendukung konsumsi air berkelanjutan yaitu mengadakan program penyadaran dan sosialisasi kepada masyarakat selaku pengguna air., Water development and supply are carried out by the government to ensure that people achieve proper and sustainable access to clean water and sanitation. Bogor City is the largest city in the use of clean water in West Java, where the distribution of clean water to the community is increasing every year. The purpose of this study is 1) to analyze people's perceptions and behaviors towards sustainable water consumption, 2) to identify changes in water consumption patterns before and during the pandemic and what factors affect them, and 3) to analyze alternatives to sustainable water consumption support strategies. This study used Likert-scale analysis, multiple linear regression analysis, quantitative descriptive analysis, and weighted sum model analysis. Research results show that people strongly agree with sustainable water consumption and that most of their behavior in water use shows sustainable water consumption. People's water consumption has changed, in that there was an increase in water use for activities that needed water during the pandemic, which had an impact on the average cost of water bills of IDR 19,950 per month. Education levels, household income, and water prices affect people's water consumption. A strategy that can be carried out to support sustainable water consumption is to conduct a wiretapping and socialization program for the community as water users.

Judul: Raw Water Characteristics and Analysis of Water Sources Management at Household Scale in Babakan Raya Village Bogor Regency
Abstrak: Desa Babakan Raya merupakan lingkungan pemukiman dengan jumlah penduduk yang padat. Penelitian ini dilakukan dengan tujuan untuk menganalisis karakteristik sumber daya air di Desa Babakan Raya Kabupaten Bogor dan kualitas air minumnya, mengidentifikasi pola perilaku penggunaan air pada skala rumah tangga, serta pola pengolahan air yang dilakukan. Penelitian ini dilakukan dengan pengambilan sampel air, pengujian sampel di lokasi, wawancara dengan warga, pengujian sampel di laboratorium dan analisis data. Kualitas sumber air minum berdasarkan parameter fisika sudah sesuai dengan standar baku mutu, tetapi berdasarkan parameter kimia air sumur memiliki pH di bawah baku mutu yang berlaku. Berdasarkan parameter biologi kualitas air tidak memenuhi standar yang berlaku. Pola perilaku penggunaan air pada masyarakat Desa Babakan Raya relatif sama dan pengolahan sumber daya air belum terlaksana dengan efektif, yang terlihat dari kualitas air yang kurang baik. Pemilihan sumber air yang digunakan tidak dipengaruhi oleh karakteristik responden., Babakan Raya Village is a residential area with a dense population.

This research was conducted by taking air samples, testing samples on site, interviews with residents, testing samples in the laboratory and analyzing data. The quality of drinking water sources based on physical parameters is in accordance with quality standards, but the chemical parameters of well water have a pH below the applicable quality standards. Based on the biological parameters, the water quality does not meet the applicable standards. The pattern of water use behavior in the Babakan Raya Village community is relatively the same and water resource management has not been implemented effectively, which can be seen from the poor water quality.

Judul: Studi histopatologi organ limpa hamster (Mesocricetus auratus) yang Diinfeksi Coxiella burnetii
Abstrak: Query fever is a zoonosis caused by Coxiella burnetii (C. burnetii). The aim of this research was to determine the histopathological changes of spleen of hamster (Mesoscricetus auratus) which were infected by C. burnetii using Haematoxylin-Eosin (HE) and Immunohistochemistry (IHC) methods. This research used 6 hamsters which were devided into two passage. The histopathological examination picture with HE staining of first passage in hamsters showed relatively similar results with those the second passage such as red pulp hemorrhage and infiltration of inflammatory cells. Histopathological observation of spleen from first passage hamster by using IHC staining showed the positivity was unclear compared to the second passage hamster.
