Judul: Analisis Pengaruh Aktivitas Lalu Lintas terhadap Suhu Udara di Stasiun Observasi Klimatologi Baranangsiang Bogor
Abstrak: The accuracy of weather and climate data is very important to note. Suitability and feasibility of a station climatology became the basis for the accuracy of the data obtained. So the feasibility of a station climatology needs to be tested whether the area around the station has a direct influence on the observations. The purpose of the implementation of this study was to analyze the effect of traffic activity to air temperature observed at the observation station climatology Baranangsiang Bogor. The variation in air temperature can be explained by the amount of solar radiation, but can be influenced by other factors too. Location of observation stations climatological Baranangsiang is beside Padjadjaran highway so it can be assumed that other factors affecting the air temperature at the station is traffic activity. The results of analysis air temperature on holidays and weekdays leave a difference on observations in the morning, afternoon, or evening. Thus, traffic activity in the Bogor does affect the character of the air temperature at the station climatology Baranangsiang. Therefore, data from observation stations can not be used to represent weather and climate data at Bogor area.

Judul: Spatial Modeling of land surface temperature and its relationship wityh ecological factors in Bogor municipilaty
Abstrak: Salah satu parameter kunci permukaan bumi melalui proses pertukaran energi dan air dengan udara disebut sebagai Suhu Permukaan Tanah (SPT), SPT juga memainkan peranan penting dalam berbagai penelitian ilmiah, seperti ekologi, hidrologi, dan studi perubahan global. Struktur buatan manusia seperti jalan dan bangunan biasanya memiliki nilai albedo yang lebih rendah dari permukaan bumi dan menyerap lebih banyak radiasi sinar tampak. Hal ini menunjukkan bahwa penurunan dan peningkatan jumlah vegetasi pada permukaan bumi wilayah perkotaan akan menyebabkan efek pulau panas. Tujuan penelitian ini adalah untuk membangun permodelan spasial suhu permukaan tanah di Kota Bogor menggunakan citra satelit Landsat-8, dan untuk mengidentifikasi hubungannya dengan faktor-faktor ekologi. Algoritma Split-Window (SW) digunakan untuk membuat SPT dengan menggunakan input berupa suhu kecerahan, emisivitas permukaan tanah (EPT) dan uap air. Validasi citra dilakukan untuk mengevaluasi nilai SPT dihitung dari citra satelit tahun 2014 Kota Bogor dengan pengukuran suhu lapangan yang dilakukan selama bulan Maret 2015 pada tanggal 2, 4, 7, 9, 11, 14, 16, 18, 21, 23, 25, 28 dan 30., One of the key parameter in the physics of the earth surface through the process of energy and water exchange with the atmosphere called as the Land Surface Temperature (LST), it also plays an important role in a wide variety of scientific studies, such as ecology, hydrology, and global change studies. Man-made structures such as roads and buildings typically have a lower albedo than the natural surface and absorb more visible radiation. This shows that the reduced of the vegetation and the increased in urban surface will cause heat island effect. The objective of this study are to develop spatial modeling the land surface temperature distribution in Bogor Municipality using landsat-8 satellite imagery, and to identify its relationship with the ecological factors. Split-Window (SW) Algorithm was used to derive the LST by using the inputs of the brightness temperature, land surface emissivity (LSE) and water vapor. The image validation was done to evaluate the relationships among LST calculated from a 2014 satellite image of the Bogor Municipality and ground-based temperature measurements monitored during the month of March 2015 at a specific date of 2, 4, 7, 9, 11, 14, 16, 18, 21, 23, 25, 28 and 30.
