Judul: Analisis Ketersediaan Air dengan Metode Thomas Fiering di Kali Krukut, Jakarta
Abstrak: The population in Kali Krukut river basin increased from year to year, so water demand in Kali Krukut increased. This research aimed to analyze the water availability in Kali Krukut using Thomas Fiering method. Based on discharge data from 2001-2009, analyses were performed to estimate the amount of discharge in 2010-2020. The result showed that a maximum discharge would occur in February 2017 approximately 20,80 m3/sec, while a minimum discharge would be 0,8554 m3/sec in December 2014 and 0,0569 m3/sec in December 2015. By 2020, the Goverment planned to increase food security, so a good water irrigation system is needed. Based on the result, the maximum water availability in rainy and dry season could fulfill the water demand, but the minimum water availability in rainy and dry season couldn’t fulfill the water demand. To solve this problem, the Goverment must create a well plan in order to manage Kali Krukut.

Judul: Analisis Potensi Dan Ketersediaan Air Berdasarkan Neraca Air Di Das Brantas Hulu, Jawa Timur (Studi Kasus Tahun 1995,1996 dan 1997)
Abstrak: Air merupakan bahan yang mutlak diperlukan oleh mahluk hidup. Ketersediaan air relatif tetap, sedangkan kebutuhan .akan air cenderung terus meningkat. Hal ini mendorong terjadinya persaingan antar berbagai kepentingan penggunaan air. DAS Bralitas Hulu mempunyai potensi air yang cukup besar sekitar 12 milyar m'itahun dengan curah hiljan rata-rata mencapai 2.000 mmltahun. Namun yang dimanfaatkan hanya sekitar 2,6 - 3,O milyar m3/tahun. Salah satu cara untuk mengetahui potelisi ketersediaan air dapat dilakukan dengan menggunakan metode neraca air.

Judul: Characterization Of Psen2 Gene Of Amyloid Disorder Of Alzheimer's Disease In Macaca Fascicularis
Abstrak: Presenilin2 (PSEN2) genes are the primary component of γ-secretase, responsible for the amyloid precursor protein sequence of proteolytic cleavage and the subsequent formation of amyloid β peptides. 18 RNA samples from the brain cortex and hippocampal regions of an adult group (10-12 years old); 4 female) and an old group (>15 years old; 5 females) of Cynomolgus monkey (Macaca fascicularis) were analyzed using RT-qPCR. There were no differences in PSEN2 mRNA expression in the cortex in between groups (p=0.063). There were significant differences in mRNA expression in the hippocampus in between groups (p= 0.010). The overall PSEN2 expression level was higher in the adult monkey group and correlated early onset Alzheimer’s disease (EOAD) characteristics in relatively young individuals. The overall PSEN2 expression level was low in the old monkey group. High PSEN2 expression in an adult group might correlate with the regulation of neuronal plasticity, amyloid precursor protein processing, and tau aggregation. It was increased in PSEN2 expression correlated with learning and memory impairment in the cortex and hippocampus. Alteration in PSEN2 expression may be a risk factor for Alzheimer’s disease. This study proposes that PSEN2 informational mutations could be included as useful gene biomarkers for the comprehensive prognosis of Alzheimer's disease in the Omnibus Gene Expression (GEO) database.
