Potential Roles of Biotic Factors in Regulating Zooplankton Community Dynamics in Jakarta Bay Shallow Water Coastal Ecosystem
The dynamics in zooplankton abundance were regulated by changes in water physical-chemical parameters and interaction with biotic factors. In this research we examined the relationship between zooplankton community dynamic and important biotic factors, such as predation and food availability, in Jakarta bay. Plankton samplings were done in 10 sampling stations in Jakarta bay, from July to November 2009. Zooplankton samples were collected using horizontal towing method with NORPAC plankton net (mesh size 300 μm). Salinity, water depth, water temperature, and water transparency were measured. Phytoplankton samples were also collected with the same method as zooplankton, using Kitahara plankton net (mesh size 80 μm). Zooplankton taxas were grouped into two groups, the prey and predatory zooplankton. The results showed that there were two different patterns in zooplankton groups dynamic i.e., the single and double peak. The abundance peak in most zooplankton groups, such as copepods, cirripeds, luciferids, and tunicates, were induced by the high food availability during the phytoplankton bloom in August. The high abundance of prey zooplankton groups in August was responded by the predatory zooplankton groups, resulting in high abundance of predatory zooplankton in adjacent month. The high abundance of ctenophores and chordates (fish larvae) were suggested as the main factor for the low abundance of other zooplankton in September. Physical and chemical factors were not the regulating factors due to the stability of those factors during this research period. Thus we concluded that food availability and predator-prey interaction were the main factors which regulate zooplankton community dynamics in Jakarta bay

Karakteristik Yoghurt Probiotik Rosella Berbahan Baku Susu Kambing dan Susu Sapi Selama Penyimpanan Suhu Ruang
Yogurt is a milk-based fermented products using Lactobacillus bulgaricus and Streptococcus thermophilus bacteria, as the starters, or any compatible lactic acid bacteria (LAB). Recently, probiotic yoghurt has been developed by adding LAB displaying probiotic properties, such as Lactobacillus acidophilus, L. casei, and Bifidobacterium. Yoghurt has also been developed with the addition of some natural ingredients, including rosella (Hibiscus sabdariffa L), which was known to exhibit antioxidant and antibacteria activities. Accordingly, the addition of rosella extract into yoghurt could increase human’s health. This research aims to investigate the characteristics of probiotic yogurt with the addition of 1% rosella extract on different storage period at room temperature with the use of goat’s milk and cow’s milk as ingredients. The results showed that there were no interaction between type of yoghurt (goat’s milk and cow’s milk) and storage duration (0, 4, 8, 12, 16, and 20 hours) at room temperature (29–30 oC) to all of tested variables. Different types of yogurt significantly affected (P>0.05) pH and highly significantly affected (P>0.01) on viscocity, water activity, and total lactic acid. Different storage duration highly significantly affected (P>0.01) on total lactic acid, pH, and total LAB.

Analisis Efisiensi Teknis Produksi Nanas: Studi Kasus Di Kabupaten Subang, Jawa Barat
EnglishLow productivity of pineapples in West Java Province is mainly due to the unfavorable climate and farmers' inability to adopt the technology fully. Objectives of the study were to analyze of technical efficiency and to examine the determinants of inefficiency by estimating land productivity, ratio of pineapple farm income to labor cost, R/C ratio, age, experience, education, total farmers' household members, membership of farmers' group, and intercropping practice. The study used data collected through a survey from 140 rural households in Subang Regency, West Java Province. Data Envelopment Analysis (DEA) results showed that pineapple production of farmers are technically inefficient with the mean technical efficiency level of 55.2 percent for CRS-DEA, 78.8 percent for VRS-DEA, and 70.4 percent for SE-DEA, respectively. Land productivity, R/C ratio, and farmers' group membership influenced negatively and significantly on inefficiencies. Intercropping practice affected significantly the technical inefficiency of pineapple production. The findings suggested that improving pineapple production is possible by applying monoculture cultivation and supporting farmers' group activities. Fully applied good agricultural practice (GAP) will enhance land productivity and R/C ratio.IndonesianRendahnya produktivitas produksi nanas di Provinsi Jawa Barat umumnya disebabkan faktor iklim dan ketidakmampuan petani untuk menggunakan teknologi seutuhnya.

Penelitian ini menggunakan data yang didapatkan dari survei 140 rumah tangga petani di Kabupaten Subang, Provinsi Jawa Barat. Hasil Data Envelopment Analysis (DEA) menunjukkan bahwa petani tidak efisien secara teknis dalam produksi nanas dengan rata-rata tingkat efisiensi teknis masing-masing sebesar 55,2 persen untuk model CRS-DEA, 78,8 persen untuk model VRS-DEA dan 70,4 persen untuk model SE-DEA. Model regresi Tobit dalam menghitung faktor yang menentukan inefisiensi teknis mengungkapkan bahwa produktivitas lahan, rasio R/C, dan keanggotaan kelompok tani memiliki pengaruh yang negatif dan signifikan, sedangkan aplikasi pola tanam tumpangsari berpengaruh positif dan signifikan pada inefisiensi teknis produksi nanas. Temuan ini menyarankan produksi nanas di lokasi penelitian akan meningkat secara signifikan dengan mengaplikasikan pola tanam monokultur, mendukung kegiatan kelompok tani, serta meningkatkan produktivitas lahan dan rasio R/C dengan mengaplikasikan GAP sepenuhnya
Effect of human granulosa cells vitrification on the expression of oocyte secreted factors
Background: Oocyte vitrification is a helpful fertility preservation technique for women at risk of losing their ovarian
functions. Meanwhile, its application extends with the emerging trend of delayed childbearing, postponed marriage, and
further diverse ethical, medical, legal, and social implications. Whereas its effect on oocytes has been widely elucidated, the
potential impact of this procedure on the biological functions of granulosa cells remains poorly understood. The present study
aimed to assess vitrification’s effect on the granulosa cells (GCs).
Methods: 35 women with polycystic ovary syndromes who underwent in vitro fertilization (IVF) in Morula IVF Jakarta Clinic
were recruited. The expression of prominent oocytes secreted factors (OSFs), including GDF-9 and BMP-15, were measured
at messenger RNA (mRNA) levels. GCs from mature and immature oocytes were collected and calculated separately. Relative
expression of GDF-9 and BMP-15 was quantified by a real-time quantitative PCR (RT-qPCR). All of the data was analyzed by
using SPSS. Bivariate analysis used the Mann-Whitney test at a 95% confidence level. A significant p-value was ≤ 0.05.
Results: The mean age of subjects was 32,39 ± 3,33 years old, with the mean duration of infertility being six years. The mean
BMI, anti-Mullerian hormone (AMH) level, and antral follicle count (AFC) were 24.04 kg/m2, 3.43 ng/mL, and 15 follicles,
respectively. The basal FSH, LH, estradiol, and progesterone were at the normal level. The expression of GDF-9 decreased
significantly (0.5-fold, p < 0.01) in the immature vitrified GC group but was not in the mature-vitrified GC group. Meanwhile,
the expression of BMP-15 was stable in all examined groups (P>0.05).
Conclusion: Our results suggest that vitrification may alter oocyte maturation, as demonstrated by reduced GDF-9 expression
in the immature vitrified GC group. Keywords: vitrification, granulosa cell, GDF-9, BMP-15
