"Gastroduodenal mucosat integrity has important role in the pathogenesis of gastroduodenal ulcer. It depends on imbalance between aggressive and defensive factors. However, many experts believe that defensive factors has more dominant role. Maintenance of gastrointestinal endothelial integrity appears to define the "cytoprotection" phenomenon and, as discussed below, is a critical component of NSAID-induced GI injury and a potential target for therapeutic intervention,"

"ABSTRAK
Sampai sekarang, belum ada rekomendasi vaksin maupun anti-viral untuk virus
Dengue. Menimbang besarnya masalah demam berdarah di sektor kesehatan
masyarakat di Indonesia, penemuan obat demam berdarah sangatlah diperlukan.
Sulokrin, senyawa yang diisolasi dari Aspergillus terreus diketahui dapat
menghambat pertumbuhan HCV, sesama virus flaviviridae seperti virus dengue.
Riset ini bertujuan untuk menginvestigasi adanya aktivitas antiviral dari senyawa
sulochrin sebagai obat demam berdarah yang potensial. Antiviral assay dilakukan
terhadap sel huh7 yang telah diinfeksi virus dengue. Sulokrin dengan 6
konsentrasi berbeda diuji cobakan untuk mengetahui nilai maksimum
penghambatan 50% sel (IC50) dengan metode Focus Assay. Efek toksisitas
(CC50) diukur dengan menggunakan metode MTT Assay. Indeks selektivitas
ditentukan melalui ratio CC50/IC50. Aktivitas inhibisi signifikan senilai 91,78%
(p=0.005) ditemukan pada konsentrasi sulokrin 80μg/ml. Ketika konsentrasi
sulokrin diturunkan menjadi 40μg/ml dan 20μg/ml, aktivitas inhibisi turun
menjadi 39.73% (p=0.02) dan 17.69 (p=0.09). Pada konsentrasi sulokrin 10μg/ml,
aktivitas inhibisi tidak teramati (p=0.98). Peningkatan pertumbuhan virus dengue
ditemukan pada konsentrasi sulokrin dibawah 10μg/ml, tepatnya pada
konsentrasi 5μg/ml dan 2.5μg/ml dengan nilai inhibisi -11.32% (p=0.21) dan -
2.35% (p=0.38). Hasil penelitian mendapatkan nilai IC50 sebesar 56.86μg/ml,
CC50 sebesar 150.85μg/ml dan SI sebesar 2.65. Sebagai kesimpulan, Aspergillus
terreus (sulokrin) menunjukan kedua sifat inhibisi dan peningkatan pertumbuhan.
Meskipun demikian, rendahnya nilai toksisitas ekstrak menunjukan karakteristik
yang baik untuk sebuah antiviral. Eksplorasi lebih lanjut dengan derivat sulokrin
perlu dilakukan untuk mengetahui aktifitas inhibisi terhadap virus dengue dari
senyawa murni.

ABSTRACT
To date, there is no approved vaccine and anti-viral regime for Dengue fever.
Considering how dengue fever poses a significant burden to Indonesian public
health sector, discovery on therapeutic agent against DENV is imperative.
Sulochrin, a compound isolated from Aspergillus terreus is known to potently
inhibit HCV, a flaviviridae virus similar to DENV. This research aims to
investigate the anti-viral activity of sulochrin from Aspergillus terreus as a
possible cure for DENV infection. Anti-viral assay of Sulochrin is evaluated in
Huh7 infected cells. 6 different concentrations of Sulochrin (80μg/ml, 40μg/ml,
20μg/ml, 10μg/ml, 5μg/ml, and 2.5μg/ml) were given to measure its half maximal
inhibitory concentration (IC50) using Focus Assay. Toxicity effect was measured
using MTT Assay (CC50). Selectivity Index was determined through ratio of
CC50/IC50. Significant inhibition of 91,78% was observed upon treatment with
sulochrin 80μg/ml (p=0.005). As concentration was decreased to 40μg/ml and
20μg/ml, inhibition activity decreased accordingly to 39.73% (p=0.02) and 17.69
(p=0.09) respectively. At treatment concentration of 10μg/ml, zero inhibition was
observed similar to control DMSO (p=0.98). An improved in replication was seen
with treatment below 10μg/ml, with -11.32% (p=0.21) and -2.35%(p=0.38) at
concentration of 5μg/ml and 2.5μg/ml respectively. The results also showed half
maximal inhibitory concentration of 56.86μg/ml (IC50), half toxicity
concentration of 150.85μg/ml (CC50) and Selectivity Index of 2.65. To conclude,
Aspergillus terreus (sulochrin) exert both anti-viral and enhancement activity to
DENV. Nonetheless, its low cytotoxic value reflects a favorable feature for
potential anti-viral. A further exploration on its derivate should be done to find the
pure compound inhibition activity to DENV."

"Anak usia sekolah 6-12 tahun, di kota besar mempunyai aktivitas flsik yang kurang dan gaya hidup yang santai. Fast food dan soft drink yang dikonsumsi mengandung kalori dan protein tinggi berasal dari protein dan karbohidrat. Obesitas mempunyai dampak terhadap tumbuh kembang anak terutama aspek psikososial. Faktor yang turut berperan mendukung terjadinya obesitas pada anak adalah keadaan sosial ekonomi, perilaku dan gaya hidup serta pola makan. Dilakukan penelitian deskriptif analitik secara seksi silang pada murid sekolah dasar di Jakarta, utituk mengidentifikasi faktor yang berperan pada obesitas anak usia sekolah. (Med 3 Indones 2006; 15:43-54).

School-aged children of 6-12 year old in big cities have less physical activities and relax life style. Fast food and soft drink consumed contain high calorie and protein of protein and carbohydrate sources. Obesity has impact on children's growth and development especially on psychosocial aspect. The factors that play a role in supporting the obesity occurrence in children include socio-economic condition, behavior and life style and diet. A cross sectional descriptive -analytic study was conducted on elementary school students in Jakarta, to identify factors that play roles on obesity of school-aged children.

"This article attempts to identify factors affecting participation in payment of irrigation service fees. There are five
variables comprising demographic and economic of land variables were tested to find the variables that influenced the
participation significantly. The five variables tested consisted of age and formal education as demographic variables;
land productivity, land size, and land tenure as the economic of land variables. The results showed that formal education
(demographic variable) had positive relationship and land size (economic of land variable) had negative relationship
with the participation. Positive relationship between formal education and participation in payment of irrigation service
fees meant that the participation increased as farmers’ education increased. Meanwhile, negative relationship between
land size and the participation in payment of irrigation service fees showed that the farmers’ participation would
increase as the land size owned by farmers decreased. In other words, participation in payment of irrigation service fees
was higher among farmers with small lands rather than that among farmers with large lands."

"Indonesia's infant mortality rate declined to 64' infannt deaths per
l ,000 live births in l99l _ Adolescent mothers. women who first married under
the age of lS. and mothers who did not obtain antenatal care and tetanus
immunizations were at greater risk of experiencing an infant death. In addition.
levels of infant mortality were substantially higher when births were spaced
closer together. For example, the infant mortality rate among adolescent
mothers was l25 when births were spaced less than 24 .months apart and 96
when births were separated by more than two years. Roughly half of all infant
deaths occur within the first 28 days of life in Indonesia. Findings indicate that
mothers who were less than 20 years of age. who did not have antenatal care
and tetanus immunizations. and who spaced births less than 24 months apart
were more likely to experience a neonatal death. With the exception of
antenatal care, these factors were also associated with elevated levels of
postnatal mortality (infant deaths that occur when infants are between l-l2
months of age). However, postneonatal mortality was also higher among
mothers who gave birth at home rather than in a health facility, who were
assisted at delivery by non-medical staff and who had lower levels of
educational attainment. Postneonatal mortality is determined by a broader
array of program and socioeconomic measures than neonatal mortality. and
may be reduced more readily through Family Planning/Mother and Child
Health (FPAHCH) service interventions. In order to reduce both neonatal and
postneonatal mortality. greater effort should be made to increase the age at first birth. space births more than two years. and attain higher tetanus coverage
levels among expectant mothers.

"Reformation in Indonesian government offices leads to many substantial changes, and demands
improved job performances while arguably loading employees with more work. This research aims
to understand factors that potentially influence job performance in Indonesian government offices
that carries on such reformation. Using adapted scales from previous studies, this research
investigates the role of workload, responsibility for others (level of responsibility to care for other
people) and need for achievement on employee?s performance. A survey to all full-time workers in
an Indonesian government office is conducted. Contrary to expectation, workload does not influence
employee?s performance. Instead, regression analysis demonstrates that, employee?s need for
achievement and responsibility for others are significant factors affecting individual performance.
These results are important because they highlight the significance of need for achievement for the
success of reformation in this office, and by extension for reformation in Indonesia. The results are
also interesting because this is the first study that points out to the role of responsibility for others in
influencing individual performance in Indonesia which is characterized by collectivistic culture. This
paper discusses the contributions of these results for theory and practice."

"This volume provides a comprehensive analysis of why taxpayers behave the way they do. It reveals the motivations for why some taxpayers comply with the law while others choose not to comply. Given the current global financial climate there is a need for governments worldwide to increase their revenue collections via improving taxpayer compliance. Research into what shapes and influences taxpayer behavior is critical in that any marginal improvement in understanding and dealing with this behavior can potentially have a dramatic impact upon government revenue"

Bacillus spp. berpotensi sebagai agen biokontrol untuk meminimalisir kontaminasi mikroorganisme. Tujuan dari penelitian ini adalah untuk mengetahui aktivitas antagonistis sel dan filtrat Bacillus siamensis LDR terhadap beberapa spesies kapang. Purifikasi dan karakterisasi morfologi dilakukan pada medium PDA. Uji aktivitas antagonistis dilakukan dengan metode dual kultur dan uji antibiosis dilakukan dengan menggunakan filtrat fermentasi B. siamensis LDR yang diperoleh dari panen hari ke-12 dan ke-14. Persentase inhibisi ditentukan berdasarkan perhitungan pertumbuhan radial dan biomassa kapang yang diberi perlakuan, dibandingkan dengan kontrol. Hasil uji antagonistis menunjukkan bahwa Fusarium oxysporum, Aspergillus flavus AHM, dan Aspergillus clavatus ABH berhasil dihambat sebesar 35,92%, 42.75%, 27.18% pada teknik dual disc dan sebesar 92.94%, 87.15%, 85.45% pada teknik pour plate disc. Hasil uji antibiosis menunjukkan inhibisi F. oxysporum, A. flavus AHM, dan A. clavatus ABH lebih tinggi pada filtrat 14 hari, yaitu 41.84—41,94%, 34,83—36,04%, 63.27—63,81% pada medium PDA dan 53,15—76,37%, -151— -11.01, 88.87—90.36% pada medium PDB. Sel dan filtrat B. siamensis LDR memiliki aktivitas antagonistis terhadap Fusarium oxysporum, Aspergillus flavus AHM, dan Aspergillus clavatus ABH dengan ketidakstabilan aktivitas antibiosis terhadap A. flavus AHM, secara in vitro.

 


Bacillus spp. are potential biocontrol agent to reduce crop contamination by microorganism. Aim of this research is to screen antagonistic activity of B. siamensis LDR cells and filtrate against few species of filamentous fungi. Purification and morphological characterization were done on PDA. Screening of antagonistic activity was done by antagonistic assay using dual culture method and antibiosis assay using 12 and 14 days fermentation filtrate of B. siamensis LDR. Percentage of inhibition were determined by comparing radial growth and biomass of treated fungi to untreated fungi as control. Result of antagonistic assay showed Fusarium oxysporum, Aspergillus flavus AHM, and Aspergillus clavatus ABH were inhibited for 35,92%, 42.75%, 27.18% by using dual disc technique and 92.94%, 87.15%, 85.45% by using pour plate disc technique, respectively. Result of antibiosis assay showed the highest inhibition activity against F. oxysporum, A. flavus AHM, A. clavatus ABH was found in 14 days fermentation filtrate, which were 41.84—41,94%, 34,83—36,04%, 63.27—63,81% on PDA and 53,15—76,37%, -151— -11.01, 88.87—90.36% on PDB, respectively. Therefore, B. siamensis LDR cell and filtrate has antagonistic activity against Fusarium oxysporum, Aspergillus flavus AHM and Aspergillus clavatus ABH, despite of unstable antibiosis activity against A. flavus AHM, in vitro.
