Judul: The Characteristic of Atmospheric Boundary Layer in West Sumatera (Case Study: Forest and Land Fires on 2015, 2016, and 2019)
Abstrak: Kebakaran hutan dan lahan sering terjadi di Indonesia sepanjang tahun 2015 hingga 2021. Saat kebakaran hutan dan lahan, suhu permukaan dan udara akan meningkat sehingga memengaruhi karakteristik Lapisan Batas Atmosfer (LBA) atau disebut dengan Planetary Boundary Layer (PBL). Penelitian bertujuan untuk menganalisis dan membandingkan karakteristik ABL saat kebakaran hutan pada September 2015, 2016, dan 2019. Penelitian menggunakan data Radiosonde Bandara Internasional Minangkabau yang bersumber dari data NOAA dengan. semua data radiosonde diolah menjadi profil vertikal suhu potensial virtual, kelembapan spesifik, kecepatan angin, dan Bulk-Richardson -number. penentuan ketinggian Mixed Layer adalah saat nilai suhu potensial virtual mengalami peningkatan tajam dan pengestimasian nilai Turbulent Flow Thickness dengan melihat nilai RiB yang dihasilkan kurang dari nilai Critical Richardson Number (RiC). Ketinggian Mixed Layer tertinggi berada pada tahun 2015 yaitu mencapai ketinggian 3.779 m dengan selisih 2.206 m dengan ketinggian mixed layer saat kondisi normal sehingga kebakaran hutan dan lahan memengaruhi ketebalan Atmospheric Boundary Layer., Forest and land fires often occur in Indonesia from 2015 to 2021. During forest and land fires, surface and air temperatures will increase, affecting the characteristics of the Atmospheric Boundary Layer (ABL) or with other name of Planetary Boundary Layer (PBL). Study aims to analyze and compare the characteristics of ABL during forest fires in September 2015, 2016, and 2019. This study uses Minangkabau International Airport Radiosonde data sourced from NOAA data. All radiosonde data is processed into a vertical profile of virtual potential temperature, specific humidity, wind speed, and Bulk-Richardson number. The determination of the height of the Mixed Layer is when the virtual potential temperature value has a sharp increase and the estimation of the Turbulent Flow Thickness value by looking at the resulting RiB value is less than the Critical Richardson Number (Ric) value. The highest mixed layer height was in 2015 which reached a height of 3.779 m with a difference of 2.206 m from the mixed layer height under normal conditions. So, forest and land fires affected Atmospheric Boundary Layer’s Thickness

Judul: Analisis Karakteristik Parameter-Parameter Atmospheric Boundary Layer dengan Data Radiosonde (Studi Kasus : Kota Serang)
Abstrak: Atmospheric Boundary Layer as the air layer directly affected by the earth’s surface where the surface effects (friction, heating and cooling) felt directly on a time scale less than a day. Case study in this paper is Serang. The data used is the radiosonde data. In describing the atmospheric boundary layer requires a parameter, such as the virtual potential temperature, mixing ratio, and wind speed. Sketch the pattern of vertical virtual potential temperature continued to rise during the day on SL layer, then decreased and more homogeneous in the ML layer, increased in tiitk CI with the result that CI is higher than the night, early morning, or late afternoon. Vertical profiles of Mixing ratio, maximum humidity during the day will continue to decline at the surface and in the lining of SL, when entering the ML layer, as the turbulence becomes homogeneous, and when it reaches the CI. Wind speeds in Region Attacking at night more than early morning (01.00) morning (at 07.00) and afternoon (13:00), it is because there is a strong influence of intense turbulence during the day.

Judul: Anatomi Otot Wajah Kancil (Tragulus napu)
Abstrak: Kancil merupakan hewan ruminansia terkecil di dunia yang mulai banyak digunakan sebagai model untuk penelitian ternak ruminansia besar. Untuk mengetahui sejauh mana kancil dapat digunakan sebagai hewan model penelitian diperlukan data-data ilmiah yang bersifat biologis dari hewan ini. Untuk itu dilakukan studi anatomi otot wajah terhadap 6 ekor kan- cil (Tragulus napu). Hasil penelitian menunjukkan bahwa kancil mempunyai bentuk dan susunan otot-otot wajah yang lebih mirip dengan kambing dan domba daripada sapi. Disamping itu didapatkan pula satu otot yang keadaannya mirip dengan M. retractor anguli oculi pada anjing…
