Judul: Karakteristik Udara Atas Wilayah Bandar Udara Soekarno-Hatta Menggunakan Program RAOB Studi Kasus Tahun 2007-2008
Abstrak: This paper describes the upper air characteristic using the RAOB program. The focus is in significant level of upper air vertical stability, the significant level describe by Level of Free Convective (LFC), Lifting Condensation Level (LCL) and Convective Condensation Level (CCL). This research was using sounding data from Soekarno-Hatta air port at December 2007 to November 2008. The upper air characteristic is very different in every few month because the implication of seasonal change in object area. The comparison between rainy season (December-January-February) and dry season (June-July-August) had shown the different pattern of upper air characteristic and diurnal variation. The different amount of wet air for this two group of months was describe using cross section from RAOB program application

Judul: Analisis Keterkaitan Struktur Vertikal Atmosfer Terhadap Pembentukan Awan Kovektif (Studi Kasus: Bandara Soekarno Hatta).
Abstrak: Pembentukan awan konvektif dapat dianalisis dengan menggunakan perangkat lunak RAOB (Rawinsonde Observation Program). Penelitian ini bertujuan untuk mengetahui profil vertikal atmosfer di Bandara Soekarno Hatta tahun 2014, menganalisis keterkaitan antara 27 indeks RAOB terhadap kondisi vertikal atmosfer, dan melakukan analisis terhadap indeks RAOB yang memiliki kontribusi tertinggi dengan pembentukan awan konvektif. Penapisan indeks-indeks RAOB dilakukan untuk mendapatkan indeks dominan yang mempengaruhi pembentukan awan konvektif. Nilai mixing ratio dijadikan sebagai variabel y dalam melakukan analisis regresi berganda dan variabel-variabel x merupakan indeks RAOB. Hasil penelitian ini didapatkan pola vertikal atmosfer yang berbeda pada bulan basah (Januari) dan bulan kering (Agustus) yang meliputi suhu udara, suhu titik embun, kelembaban relatif, kecepatan angin, dan mixing ratio. Setiap indeks RAOB memiliki keterkaitan masing-masing dengan adanya awan konvektif, baik terkait langsung (14 indeks) maupun tidak langsung (13 indeks). Indeks RAOB yang dominan dari 27 indeks yang dianalisis pada penelitian ini yaitu showalter index, CCL (Convective Condensation Level), PW (Precipitable Water), dan Kindex dengan rata-rata kontribusi pada tahun 2014 sebesar 59%, 35%, 31%, dan 23%.

Judul: Acute Oral Toxicity Lethal
Dose 50 (LD50) of Cayenne Pepper (Capsicum annuum) Infusion in DDY Strain
Mice (Mus musculus)
Abstrak: In recent years, there has been a growing interest in herbal remedies such as cayenne pepper which is known for its versatility beyond its culinary use. Cayenne pepper’s phytochemicals, including capsaicinoids, carotenoids, phenolic compounds, vitamins, and minerals, offer antioxidant, antimicrobial, and antiinflammatory properties, making it a valuable ingredient in various fields such as veterinary medicine, agro-food, cosmetics, and pharmaceuticals. However, concerns regarding the potential risks of cayenne pepper consumption as herbal medicine arise. This study aims to determine the acute oral toxicity lethal dose 50 (LD50) of cayenne pepper infusion in female DDY strain mice and its effects on the mice's organs. The research involved 20 DDY strain female mice divided into 4 groups which are control group (administered with distilled water) and treatment groups that are given cayenne pepper infusion at doses of 5, 10, and 15 g/kg BW orally. The observed variables included mortality, clinical symptoms, physiological responses, and organ weight. Acute toxicity testing indicated that the cayenne pepper infusion falls into the category of practically non toxic formulations. Administration of the cayenne pepper infusion up to a dose of 15 g/kg BW did not induce toxicity symptoms, such as clinically pathological symptoms, macro anatomical organ changes, or mortality nor affect both weight gain and loss.
