PENGARUH PERENDAMAN DAN DURASINYA DALAM LARUTAN MADU TERHADAP MASKULINASASI LARVA Oreochromis niloticus

Budidaya ikan nila monoseks jantan memiliki peranan penting dalam meningkatkan produksi ikan nila. Meskipun saat ini teknik maskulinisasi menggunakan hormon sintetik umum diterapkan namun cara ini berbahaya dari segi keamanan pangan dan konsumen karena sifat karsinogenik dan potensi akumulasi di alam dari hormon sintetik. Sebaliknya, bahan alami seperti madu yang menggandung Chrysin, yang telah diketahui sebagai aromatase inhibitor yang dapat menyebabkan maskulinisasi pada ikan dapat digunakan dalam teknik maskulinisasi. Meskipun demikian, sejauh ini pengaruh perendaman larva ikan nila dalam larutan madu terhadap maskulinisasi masih harus dikaji. Penelitian ini bertujuan untuk mengetahui pengaruh perendaman dan durasi perendaman dalam larutan madu terhadap rasio kelamin jantan benih ikan nila. Menggunakan larva berumur 7 hari hasil pemijahan semi-buatan dengan induksi hormon, penelitian ini dilakukan menggunakan 4 perlakuan (durasi perendaman) dengan 1 konsentrasi (15 mL/L). Untuk mengetahui rasio kelamin jantan, analisa histologis dengan pewarnaan asetokarin dilakukan untuk mengamati gonad benih hasil perlakuan. Perendaman larva ikan nila pada larutan madu konsentrasi 15 mL/L selama 20 jam mampu menghasilkan 80% benih berkelamin jantan. Sebagai kesimpulan, durasi perendaman berpengaruh terhadap rasio kelamin jantan yang dihasilkan dan perendaman selama 20 jam adalah durasi perendaman terbaik untuk larva ikan nila.   Farming monosex male tilapia has an important role in improving the production of Nile tilapia. Although synthetic hormone is commonly used to produce male monosex tilapia, this method poses a serious threat to food safety and consumer’s health due to carcinogenic potential and bioaccumulation of the synthetic hormone in ecosystem. In contrast, honeybee is a natural product containing Chrysin, an aromatase inhibitor, which is known to cause masculinity in fish and can be used for masculinization. To date, however, the effect of honeybee on tilapia larvae’s masculinization is yet to be studied. This research aimed to study the effect of immersion and its duration in honeybee’of Nile Tilapia’s Larvae in honeybee’s solution and length of immersion on male ratio. This research was conducted in quadruple consisting of three different times of immersion (duration of immersion) and one concentration (15 mL/L). Using 7-day post hatched Nile tilapia larvae from semi-artificial breeding, we determined male ratio based on histological analysis using acetocarmine stain. The result show that the Nile Tilapia’s larvae treated at the concentration of 15 mL/L of honeybee for 20 hours had the highest male ratio (80%). To conclude, immersion in honeybee solution affected male ratio with 20 hours length of immersion resulting in the highest male ratio for tilapia’s larvae

ANALISIS PENGARUH BREAKWATER TERHADAP TRANSPOR SEDIMEN PANTAI SINDULANG 1 SAMPAI TUMUMPA 2

Utilization of Littoral develops continuously along with economic developments and technological advancements nowadays. Therefore, special attention is needed to overcome the problems that may arise in Littoral including coastal areas. One of the most popular beach problems for this time is the unbalanced sediment transport causing Coastal Erosion. The retreat of shorelines is generally due to coastal processes such as erosion and abrasion that will harm either the local population or life sustainability.From Sindulang Beach until Tumumpa II region where is located on Boulevard II experiencing erosion and abrasion. This certainly cannot be ignored for long because besides it will be able to damage the facilities and infrastructure of society and other public infrastructure but it also can harm the lives of coastal communities.Through this paper, The Author tries to do new thing by placing breakwater as a building that has an influence on sediment transport.  We know usually The Breakwater is a Shore protector for the wave attacks, this time we try to see its effect on the sediment transport. Through this study, The Author conducts the modeling of coastline with four variations of breakwater. First Variation: The breakwater is placed in parallel against the west-east direction separately, Second Variation: the breakwater is placed in parallel against the shoreline separately but it is longer than the First Variation, Third Variation: the breakwater is placed in parallel against coastline with tightly placed and longer than First Variation, Fourth Variation: breakwater is placed in parallel against the coastline with very tightly placed and longer than First Variation. The Differences in length of breakwater causes the difference of sediment transported too. In the First Variation, sediment is transported up to 12370 m3 to the right, Second Variation; sediment is transported up to 17589 m3 to the right, Third Variation; sediment is transported up to 22682 m3 to the right, Fourth Variation; sediment is transported up to 11478 m3 to the right. Then we found the configuration of the Second Variation of breakwater beach building is most efficient. The calculation of the effect of groins on shoreline is done with Genesis Software. Before using Genesis for modeling, the Genesis should be calibrated to the calibration parameters K1, K2 and d50 afterward doa Sensitivity Test. After the Test, take the value that produces the smallest DYrms among The values of K1, K2 and d50.  The values of K1, K2 and d50 are 0.11, 0.2 and 0.5 mm. The data that must include in the genesis are wave data, initial and measured coastline, offshore depth and depth of cover. Wave data is obtained from wind data analyzed by SMB method. The wave data that include in Genesis are the period, height and direction of the wave where the wave height that include in this case is the average wave height. Keywords: Breakwater, Sediment Transport, Sindulang-Tumumpa Beach 2

Tingkah Laku Owa Jawa (Hylobates moloch) di Fasilitas Penangkaran Pusat Studi Satwa Primata, Institut Pertanian Bogor

The Javan Gibbon is a primate species endemic to Java, Indonesia and considered as an endangered species (IUCN 2008). The Primate Research Center of Bogor Agricultural University (PRC-IPB) in cooperation with Taman Safari Indonesia have established an ex situ breeding facility for the Javan Gibbon to support conservation program. The breeding was started in 2003, and up to recently, the pair of Javan Gibbons ( 15 and 7 years old) has had three offspring, and still occupy one common cage. Assessment of the Javan Gibbon’s behavior in captivity especially to the family with five individuals was conducted using focal animal sampling to provide basic behavioral data.  Moving was the greatest frequency (45.70%) of each individual compared to other behaviors, while resting was the greatest duration that occurred to the parents, and playing was the greatest duration (18.02%) to the offspring respectively.    Keywords : behavior, javan gibbon, endangered, captive breedin

Successful Intracervical Insemination and Characteristics of Anoa (Bubalus SP.) Parturation Behavior in Captivity

Anoa, which is the endemic animal in Indonesia, its population is unevitably decreasing, therefore anoa included in the list of endangered species by International Union for Conservation of Nature (IUCN). The experiment was aimed to apply the artificial insemination (AI) technique for anoa and to examine their parturition behavior. The experiment involved 2 males and 5 females anoa at Taman Safari Indonesia Bogor. Semen was collected by electroejaculator, then evaluated and diluted in Tris-egg yolk extender. The anesthetized estrous females were inseminated intracervically with extended semen (100x106 sperm/1.0 mL). Females which did not show estrous signs during 2-3 cycles after AI were predicted pregnant, and therefore confirmed by ultrasonography. As a comparison, another predicted-pregnant female after natural mating was scanned. The results showed that intracervical AI resulted pregnancy in one female, and the gestation period of anoa was ranged from 313 d (AI) to 324 d (natural mating). There were three stages of parturition process was observed: Stage 1 was characterized by the abdominal contraction and amniotic membrane rupture, Stage 2 was characterized by the fetal expulsions, and Stage 3 was characterized by the placental expulsions and ingestion of placenta by the dam. The duration of each stage of parturition was 6-8 h (stage 1), 30-60 min (stage 2), and 15-180 min (stage 3). It is concluded that AI technique was applicable to anoa in captivity, and the parturation behavior of anoa was comparable to buffalo and cattle. However, the fetal delivery occurred when the dam was in standing position and the dam ingested the placenta

Biometri Organ Reproduksi Bagian Luar Dan Karakteristik Ejakulat Anoa (Bubalus SP.) Yang Dikoleksi Menggunakan Elektroejakulator Setelah Diinjeksi HCG

This experiment aimed to investigate characteristics of reproductive organ (external parts) of the anoa (Bubalus sp.) and semen characteristics that collected by using electroejaculator after hCG injection, as an initial step on implementation of assisted reproductive techniques. Anoa is Indonesian endemic fauna that included into Appendix I by CITES. Anoa breeding efforts have not succeeded, due to their agressivity, soliter, wildness and monogamous. This experiment was carried out in Ragunan Zoo (Jakarta), Taman Safari Indonesia (Bogor), and Divison of Reproduction, Obstetrics and Gynaecology Faculty of Veterinary Medicine, Bogor Agricultural University (IPB). Biometry of reproductive organ were measured by microcaliper and nylon tape. Semen was collected by electroejaculator, under anesthetized condition. Ejaculate was evaluated macro- and microscopically. The results showed that the reproductive organ was larger as it is getting older. But, it was generally smaller compared to the buffalo\u27s. The characteristics of fresh semen were: volume 1.02±0.28 ml, pH 6.93±0.19, mass movement 0, progressive motility 52.50±18.91%, live-death ratio 67.48±8.24%, concentration 263.33±105.06 billion/mL and total abnormality 31.86±3.72% (primary abnormality 9.52±3.85%, secondary abnormality 22.33±1.46%). The semen qualities were fairly good, even though some parameters showed lower number compared to buffalo\u27s. It is important to improve the collection technique, animal handling and appropriate extender development for semen cryopreservation
