ANALISIS STATUS PEMANFAATAN SUMBER DAYA IKAN SEBAGAI DASAR PENGELOLAAN PERIKANAN TANGKAP BERKELANJUTAN DI WILAYAH PERAIRAN CIREBON
Pada dasarnya pengelolaan perikanan tangkap bertujuan untuk mewujudkan usaha perikanan tangkap yang berkelanjutan. Untuk itu, laju penangkapan ikan harus tidak melebihi potensi produksi lestari (Maximum SustainbleYield, MSY) dari sumber daya ikan dalam suatu wilayah perairan. Namun, pengelola perikanan di Indonesia umumnya berpandangan, bahwa menentukan MSY dan hasil tangkapan ikan di laut susah dan mahal. Dengan metode Surplus Production Model, penelitian ini dimaksudkan untuk mengetahui status pemanfaatan sumber daya ikan berdasarkan pada jenis alat tangkap, zona penangkapan ikan, dan jenis ikan secara lebih mudah dan murah di wilayah perairan laut Kabupaten Cirebon. Penelitian dilakukan dari Oktober 2010 sampai Maret 2011. Hasil penelitian menunjukkan, bahwa status pemanfaatan sumber daya ikan baik di Zona-I, Zona- II maupun Zona-III perairan laut Cirebon pada umumnya telah mengalami gejala tangkap lebih (overfishing). Dari 13 jenis alat tangkap yang digunakan oleh nelayan di daerah penelitian, tujuh diantaranya yakni payang, dogol, pukat arad, jaring insang hanyut, jaring insang lingkar, bagan tancap, dan rawai tetap statusnya sudah melebihi dari jumlah upaya optimum (fopt). Sedangkan, enam jenis alat tangkap lainnya, yaitu pukat tarik, jaring insang tetap, jaring kantong, anco, perangkap kerang, dan perangkap lainnya statusnya masih kurang. Adapun jenis-jenis ikan yang telah mengalami overfishing adalah: teri, teri nasi, bawal hitam, sunglir, gurita, biji nangka, kapas-kapas, slanget, sotong, kurisi, kuniran, peperek, kurau, ikan sebelah, cumi-cumi, manyung, tetengkek, bawal putih, talang, kakap, tongkol, tenggiri, cucut, japuh, tembang, julung-julung, siro, bilis, pari, alu-alu, dan remang.Management of capture fisheries is basically intended to achieve economic activities of capture fisheries on a sustainable basis. Accordingly, the exploitation rate of fisheries resources should not exceed its MSY (Maximum Sustainable Yield) in a marine area. Unfortunately, majority of fisheries management authorities in Indonesia perceive that determining MSY and total fish catch in marine waters is both difficult and expensive. By employing Surplus Production Model, this research aims at evaluating the state of fisheries resource utilization based upon the types of fishing gears, fishing zones, and types of fish stocks in Cirebon marine waters, which is easier and less expensive than it is currently perceived by those management authorities. The results of this research demonstrate that the state of fisheries resources in Zone-I, Zone-II, and Zone-III of Cirebon marine waters has generally been overfishing. Furthermore, among 13 types of fishing gears used in Cirebon marine waters, seven fishing gears are already exceeding the optimum fishing effort (fopt). These include mini purse seine, danish seine, fish net, gill nets, encirling gill nets, fixed lift net, and long lines. Meanwhile, the other six fishing gears including active purse seine, fixed gill nets, trammel nets, anco, trap for molluscs, and other trap types are still less than their optimum number. Amongst so many fish species caught from Cirebon marine waters, thirty one specieas are already overfishing, which include teri, teri nasi, bawal hitam, sunglir, gurita, biji nangka, kapas-kapas, slanget, sotong, kurisi, kuniran, peperek, kurau, ikan sebelah, cumicumi, manyung, tetengkek, bawal putih, talang, kakap, tongkol, tenggiri, cucut, japuh, tembang, julung-julung, siro, bilis, pari, alu-alu, dan remang
Pregnancy Outcome in Infertility Patient with Endometriosis Cyst after Laparoscopic Cystectomy
Objective: To investigate about the rate of pregnancy in women
who had undergone laparoscopic cystectomy.
Methods: This was a retrospective study. Data were taken from the
medical records of patients with infertility in Fatmawati Hospital,
Jakarta, Indonesia. Data then analyze to know is there any
association between age, infertility duration, bilaterality of the cyst,
tubal patensy, r-AFS stage with pregnancy rate.
Results: A total of 64 subjects were recruited in this study. There
were 23 subjects (35.9%) that got pregnant within one year after
undergoing laparoscopic procedure. Those who were 35 years old
or less had a greater chance to get pregnant (p = 0.01, OR = 6.75),
duration of infertility ï‚£ 3 years had a greater chance to get
pregnant with OR = 3.2 and p value = 0.032, r-AFS stage II and III
had a greater chance to get pregnant to with (p = 0.04, OR = 3.25
and 4.25).
Conclusion: The pregnancy rate after laparoscopic procedure is
35.9% in this study. There are correlation between age, duration
of infertility, and r-AFS staging with pregnancy rate.

Correlation between luteinizing hormone receptor gene expression in human granulosa cells with oocyte quality in poor responder patients undergoing in vitro fertilization: A cross-sectional study [version 1; peer review: 2 approved, 1 approved with reservations]
Background: This study was performed to evaluate the role of luteinizing hormone (LH) and granulosa cell LH receptor (LH-R) in poor responder patients who underwent controlled ovarian stimulation. Expression levels of LH-R mRNA in granulosa cells was investigated and compared with oocyte morphology, oocyte maturity and fertilization rate. Methods: Granulosa cells were obtained from 30 patients who underwent in vitro fertilization (IVF) at Dr. Cipto Mangunkusumo Hospital, Jakarta. The patients were divided into two groups: group I (n=10) poor responders; and group II (n=20) non-poor responders. After the extraction of total RNA from granulosa cells, semi-quantitative RT-PCR was performed and the amount of LH-R mRNA was quantified. The relative values were calculated as the ratio of LH-R mRNA and actin beta mRNA. Statistical analysis was performed using Mann-Whitney test and Spearman correlation. Results: The relative value of LH-R mRNA was higher in group I compared with group II (27.37[0.00-28939.37] vs 0.00[0.00-7196.12]). Oocyte maturity (r=0.267) and morphology (r=0.267) in group I consistently showed a positive correlation with LH-R mRNA; in group II a negative correlation with LH-R mRNA was shown for oocyte maturity (r= -0.552) and morphology (r= -0.164). Group I had a positive correlation between LH-R expression with fertilization rate (r=0.430), and group II showed a negative correlation (r=-0.340). Conclusions: The expression of LH-R mRNA has a positive correlation with oocyte quality in poor responder patients and a negative correlation in non-poor responders. Our study suggests an optimal expression of LH- R mRNA in granulosa cells during controlled ovarian stimulation to obtain good quality oocytes
