Judul: Evaluation Of Extreme Rainfall Based On Reanalysis Data From CHIRPS, ERA5, And GPM In The Konaweha Watershed
Abstrak: Iklim ekstrem adalah suatu kondisi iklim diatas atau dibawah nilai ambang batas dari rentang variabel yang diamati, seperti meningkatnya intensitas curah hujan dan frekuensi musim kemarau yang semakin panjang dari kondisi normalnya. Tujuan dari penelitian ini adalah untuk mengevaluasi kemampuan data reanalisis untuk menduga curah hujan ekstrem di DAS Konaweha. Kemampuan reanalisis data ini dihitung berdasarkan curah hujan regional, uji kualitas data, kalibrasi, koreksi bias, validasi, dan indeks ekstrem. Hasil dari penelitian ini adalah data GPM mampu menghitung R50mm dan R95p dan ERA5 mampu menghitung Rx5day. Nilai uji statistik GPM pada R50mm dan R95p memiliki nilai P, Extreme climate is a climate condition above or below the threshold value of the observed variable range, such as increasing rainfall intensity and the frequency of the dry season that is getting longer than normal conditions. The purpose of this study is to evaluate the ability of reanalysis data to predict extreme rainfall in the Konaweha watershed. This data reanalysis capability is calculated based on regional rainfall, data quality tests, calibration, bias correction, validation, and extreme indexes. The result of this study is that GPM data is able to calculate R50mm and R95p and ERA5 is able to calculate Rx5day. The GPM statistical test value on R50mm and R95p has a P value

Judul: The Impact of Convective Available Potential  Energy (CAPE) on Spatio-Temporal Variations of Indonesian Extreme Rainfall
Abstrak: Distribusi curah hujan berkaitan erat dengan dinamika dan termodinamika atmosfer. Umumnya, kondisi stabilitas atmosfer dapat merepresentasi proses pembentukan curah hujan di permukaan. Convective Available Potential Energy (CAPE) merupakan salah satu parameter atmosfer yang dapat menjelaskan kondisi ketidakstabilan atmosfer. Fluktuasi peningkatan CAPE berpotensi pembentukan awan konvektif, sehingga mengakibatkan terbentuknya curah hujan ekstrem suatu wilayah. Tujuan dari penelitian ini adalah menjelaskan berbagai kondisi spasial dan temporal dari variasi Convective Available Potential Energy (CAPE) dan curah hujan ekstrem di Indonesia, serta menganalisis hubungan korelasi nilai CAPE terhadap curah hujan dan beberapa indeks curah hujan ekstrem di Indonesia. Cropping dan subsetting merupakan tahapan awal dalam ekstraksi data curah hujan APHRODITE dan CAPE dalam analisis kondisi wilayah Indonesia. Perhitungan indeks curah hujan ekstrem telah dikembangkan oleh Expert Team for Climate Change Detection Monitoring and Indices (ETCCDMI), diantaranya indeks R95p (very wet days), CDD (consecutive dry days), CWD (consecutive wet days), R10mm (heavy rain), R20mm (very heavy rain), dan SDII (simply daily intensity index). Tahun 1983 – 2007 secara umum, wilayah Indonesia mengalami trend kejadian ekstrem dengan kategori ekstrem kering yang terlihat pada indeks CDD yang meningkat secara signifikan (p-value < 0,05), terutama pada wilayah Papua, berdasarkan uji statistik Mann-Kendall. Kontribusi CAPE terhadap curah hujan di Indonesia signifikan terjadi saat musim MAM, dan SON, dan rendahnya nilai CAPE saat musim JJA berkorelasi positif signifikan terhadap kondisi curah hujan rendah pada periode tersebut. Sedangkan, besarnya nilai CAPE menyebabkan meningkatnya indeks CWD dan R10mm, dengan koefisien korelasi positif yang signifikan, sedangkan pada indeks CDD mengalami penurunan kejadian yang signifikan, dengan koefisien korelasi negatif., Precipitation distribution is closely related to atmospheric dynamics and thermodynamics. In most cases, instability atmospheres describe the process of precipitation formation on the surface. Convective Available Potential Energy (CAPE) is one measure that takes into account instability. An increase in the CAPE parameter has the potential to cause the convective cloud effect, which causes the region's extreme rainfall. The aim of this study is to better understand the spatial and temporal variations in conditions caused by varying convection energy or Convective Available Potential Energy (CAPE) and rainfall extreme events in Indonesia, as well as the relationship between CAPE value and some rainfall extremes index. Cropping and subsetting were carried out using rainfall data from APHRODITE and CAPE from ECMWF. Based on the Expert Team for Climate Change Detection Monitoring and Indices(ETCCDMI), rainfall data was converted into the extreme rainfall index R95p (very wet days), CDD (consecutive dry days), CWD (consecutive wet days), R10mm (heavy rain), R20mm (very heavy rain), and SDII (simply daily intensity index). According to Mann-Kendall statistics, Indonesia experienced an extreme trend from 1983 to 2007, with a higher extreme category reflected in a rising CDD index (p-value<0,05), particularly in Papua. In Indonesia, the CAPE contribution to rainfall is significant during the MAM and SON seasons, and a low CAPE value during the JJA season has a significant positive correlation with low rainfall conditions during that period. Meanwhile, with a p-value of <0,05, the magnitude of the CAPE value showed a significant positive correlation to the CWD and R10mm indices and a negative correlation to

Judul: Lizard (Mabuya multifasciata) Behavior in Captivity
Abstrak: The Mabuya multifasciata lizard are known as common lizard and spread out widely in Indonesian archipelago. Traditionally, this lizard is used as skin medicine for human, protein source, raw material for leather industry and reared as a pet. To increase lizard population and to prevent lizard from extinction, it is important to breed the lizard in captivity. Therefore, their behavior in captivity was conducted.
