Judul: Analisis Korelasi antara Bangkitan Debu Jatuh, Kecepatan Angin, dan Kadar Air Tanah
Abstrak: Naturally dustfall can be generated from dry soil that carried away by the wind. The aim of the research is to analyze the correlations between dustfall, wind speed, and soil moisture content on three main types of soil found in Java Island according to Standard Rev. SNI 13-4703-1998. The results of analysis showed that the generation of dustfall correlated positively with wind speed and correlated negatively with soil moisture content. Effect of wind speed on the generation of dustfall on Inceptisol soil is 19.6%, Ultisol is 36.6%, and Andisol is 22.5%. Effect of soil moisture content on the generation of dustfall on Inceptisol soil is 27.4% on the measurements in the field and 72.6% on the measurements in the laboratory, Ultisol soil is 37.5% on the measurements in the field and 79.5% on the measurements in the laboratory, Andisol soil is 29.3% on the measurements in the field and 78.7% on the measurements in the laboratory. Many outside factors influence on the measurements in the field resulted in the resulting correlation lower than measurements in the laboratory

Judul: Analisis Bangkitan Debu Jatuh Udara Ambien dari Lima Jenis Tanah Utama di Pulau Jawa
Abstrak: Debu jatuh merupakan salah satu parameter kualitas udara dan dapat menyebabkan infeksi saluran pernapasan atas (ISPA). Tujuan penelitian ini antara lain: (1) Menganalisis korelasi antara bangkitan debu jatuh, kecepatan angin, kadar air tanah, dan persentase tutupan lahan pada lima jenis tanah utama di Pulau Jawa; (2) Mendeskripsikan pengaruh kecepatan angin, kadar air tanah, dan persentase tutupan lahan terhadap bangkitan debu jatuh; dan (3) Menyusun gambaran mengenai dampak negatif bangkitan debu jatuh berdasarkan distribusi ukuran partikel dari setiap jenis tanah. Penelitian ini dilakukan pada bulan Februari 2013-Maret 2014. Pengukuran di lapangan dilakukan pada lahan terbuka dengan jenis tanah Inceptisol di Kota Bogor, Ultisol di Kab. Bogor, Andisol di Kab. Kuningan, Entisol di Kab. Karawang, dan Vertisol di Kab. Madiun. Pengukuran di laboratorium dilakukan di Lab. Teknik Lingkungan, Departemen Teknik Sipil dan Lingkungan.Alat dan bahan yang digunakan selama pengukuran meliputi: dustfall canister [AS-2011-1], kipas angin [Hercules; Ø 60 cm; 220 V; 170 W], digital anemometer [Lutron AM-4201], digital moisture tester [OGA TA-5],terowongan [panjang 7.6 m; lebar 0.76 m; tinggi 2.4 m], neraca analitik [OHAUS Aventuror Pro], cawan petri [Ø=80 mm], filter paper 10μ [Whatmann #41], dan universal oven [UNB 400] . Hasil analisis menunjukkan bahwa bangkitan debu jatuh berkorelasi positif dengan kecepatan angin serta berkorelasi negatif dengan kadar air tanah dan persentase tutupan lahan. Pengaruh kecepatan angin terhadap bangkitan debu jatuh dari tanah Inceptisol pada pengukuran di lapangan dan di laboratorium masing-masing sebesar 19.6% dan 51.0%, tanah Ultisol 36.6% dan 88.6%, tanah Andisol 23.2% dan 84.3%, tanah Entisol 68.3% dan 61.7%, serta tanah Vertisol 63.5% dan 68.9%. Pengaruh kadar air tanah terhadap bangkitan debu jatuh dari tanah Inceptisol pada pengukuran di lapangan dan di laboratorium masing-masing sebesar 27.4% dan 44.1%, tanah Ultisol 37.5% dan 84.1%, tanah Andisol 29.4% dan 59.4%, tanah Entisol 42.8% dan 42.1%, serta tanah Vertisol 74.8% dan 49.7%. Pengaruh persentase tutupan lahan terhadap bangkitan debu jatuh pada tanah Inceptisol adalah 95.0%, tanah Ultisol 82.9%, tanah Andisol 84.5%, tanah Entisol 87.6%, dan tanah Vertisol 80.4%. Berdasarkan distribusi ukuran partikelnya, dampak negatif debu jatuh tanah Vertisol terhadap kesehatan manusia diduga paling tinggi dibandingkan jenis tanah lainnya karena debu jatuh tanah Vertisol mempunyai ukuran partikel halus yang paling banyak (76.9%) sehingga partikel tersebut berpotensi tersimpan dalam alveoli dan menganggu sistem pernafasan, sedangkan tanah Andisol dan Inceptisol diduga berdampak rendah terhadap kesehatan manusia karena partikel yang berukuran kecil relatif sedikit, yaitu 16.0% untuk tanah Andisol dan 11.1% untuk tanah Inceptisol. Namun demikian, debu jatuh berukuran kasar dapat menurunkan jarak pandang, mengganggu proses fotosintesis maupun ekosistem.

Judul: Case Study of Gallbladder Mucocele and Treatment Used In Small Animals
Abstrak: Gallbladder mucocele (GM) is defined as distention of the gallbladder caused by an inappropriate accumulation or deposition of high concentrations of bile. The purpose of this case study is to study GM conditions in small animals and to report the clinical sign and characteristics of GM through the sonogram interpretation and blood chemistry test evaluation, and studies related to the therapy given and other treatments recommended. A 14-year-old Toy Poodle dog has been diagnosed with severe GM and cholecystitis. No pain signs were shown during the physical examination as asymptomatic is a common characteristic in the early stage of biliary related diseases. In this study Abdominal ultrasonography interpretation and blood chemistry evaluation was conducted in 2021-2022 and analyzed as a secondary data source. Ultrasonography results showed presence of hyperechoic, immobile deposits in gallbladder accompanied by wall thickening and enlarged in size, followed by a significant increase in the enzyme alkaline phosphatase (ALP). This study has summarized mainly the diagnosis and treatments of GM in small animals and suitable alternatives treatments were recommended to encounter the GM conditions in small animals. The effectiveness of combined therapy shows the positive impact on the patient, the condition of GM has been under control.
