Judul: Perencanaan Geo-area Ciletuh Berbasis Mitigasi Bencana dan Karakter Lanskap di Geopark Ciletuh-Palabuhanratu Kabupaten Sukabumi
Abstrak: Penelitian ini dilakukan pada Geo-area Ciletuh, Geopark Ciletuh-Palabuhanratu, Kabupaten Sukabumi. Pada bulan April 2018, UNESCO telah meresmikan Geopark Ciletuh-Palabuhanratu sebagai bagian dari Global Geopark Network. Sejalan dengan itu, potensi dan ancaman bagi kawasan ini perlu diamati dengan baik. Besarnya potensi wisata di Geo-area Ciletuh, ternyata memiliki ancaman bencana yang bisa datang kapanpun. Sehingga tujuan dari penelitian ini adalah untuk membuat perencanaan lanskap berbasis mitigasi bencana. Proses perencanaan itu sendiri terdiri dari tahap pengumpulan dan klasifikasi data, analisis dan sintesis, dan konsep perencanaan. Analisis yang digunakan terdiri dari analisis zona ekologis lanskap, analisis resiko bencana, identifikasi karakter lanskap dan perencanaan lanskap. Hasil analisis zona ekologis lanskap menunjukan 71.13% kawasan berada pada zona ekologis sedang. Hasil analisis resiko bencana banjir menunjukan sebesar 46.36%% merupakan area rawan banjir. Sedangkan analisis resiko bencana tanah longsor menunjukan 93.87% merupakan area tidak berbahaya longsor dan 2.61% area berbahaya longsor. Berdasarkan hasil identifikasi karakter lanskap, fitur alami yang terdapat di Geo-area Ciletuh adalah perbukitan, hutan, komplek batuan, air terjun dan laut. Sedangkan fitur buatan terdiri dari perkebunan, permukiman dan peninggalan sejarah. Sebagian besar karakter lanskap di Geo-area Ciletuh didominasi oleh fitur alami. Perencanaan berbasis mitigasi bencana diperlukan pada lokasi penelitian untuk meminimalisis kerusakan atau dampak pasca bencana, karena merupakan lanskap permukiman dan wisata.

Judul: Landscape Planning of Ciletuh-Palabuhanratu Geopark based on Tsunami Mitigation
Abstrak: Geopark Ciletuh merupakan kawasan yang memiliki ragam (geodiversity) dan warisan geologi (geoheritage) yang unik. Kawasan yang terletak di Sukabumi, Jawa Barat ini terbentuk dari tumbukan lempeng Eurasia yang memiliki komposisi granit (asam) dan lempeng Indo-Australia yang memiliki komposisi basal (basa). Bagian Geopark Ciletuh yang berada di pesisir dan muara sungai, selain merupakan kawasan pantai selatan yang mempunyai gelombang besar dan laut dalam, juga merupakan kawasan yang rawan tsunami. Penelitian ini bertujuan untuk mengidentifikasi potensi dari bencana tsunami di wilayah Geopark Ciletuh, menganalisis kemungkinan wilayah yang terdampak bencana tsunami di Geopark Ciletuh, dan membuat perencanaan lanskap Geopark Ciletuh berbasis berbasis mitigasi tsunami. Penelitian ini dimulai dari persiapan, dilanjutkan dengan inventarisasi, analisis, sintesis, dan penyusunan rencana lanskap. Analisis terdiri atas analisis kerawanan bahaya tsunami, analisis kerentanan bahaya tsunami, dan analisis risiko bencana tsunami. Berdasarkan hasil analisis resiko bencana dapat dikembangkan zonasi. Selanjutnya, zonasi menjadi arahan peruntukan lahan yang dituangkan dalam perencanaan lanskap yang terdiri atas Ruang Lindung/Greenbelt, Ruang Terbuka Hijau Penyangga dan Ruang Pengembangan. Selain rencana lanskap disusun juga Rencana Evakuasi Tsunami., Ciletuh Geopark is an area that has unique geodiversity and geology. This area located in Sukabumi, West Java formed by collision of Eurasia plate that have granite composition (acid) and Indo-Australia plate that have basalt composition (base). The part of Ciletuh Geopark that close to coast and estuary, besides of south beach that has big wave and deep sea, also a tsunami prone area. This research aims to identified the potency of tsunami disaster in Ciletuh Geopark area, to analyze the possibilities of the areas affected by the tsunami in Ciletuh Geopark area, to make a landscape plan for mitigation of tsunami disaster in Ciletuh Geopark area. The research starts from preparation, continued with inventory, analysis, synthesis, and landcape planning. The analiysis consists of vulnerability analysis, sensitivity analysis, and risk analysis to tsunami. Based on the result of risk analysis, zoning can be developed. Furthermore the zoning becomes the direction of landuse as outlined in landscape plan that consists of protected space/greenbelt plan, buffer green open space plan, and development space plan. In addition to landscape plan, a tsunami evacuation plan is also prepared.

Judul: Induction of Gonad Maturation, Ovulation and Spawn in Torsoro (Tor soro) used Hormon Combination
Abstrak: Torsoro fish populations continue to decline due to overfishing and habitat destruction on the natural environment. Artificial breeding of fish has to do with hormonal stimulation, but the results are not optimal. The purpose of this study was to manipulate the reproduction of fish Torsoro through induction of gonadal maturation, ovulation, and spawning to increase the success of artificial breeding. Research on the induction of gonadal maturation performed by Oodev.Oodev containing PMSG and antidopamin that functions as a hormone regulator that works to stimulate the target organs (hypothalamic-pituitary-gonadal) for the initial development of the gonads. Induction of final maturation (final maturation) and spawning is done by using some hormones and their combinations; sGnRH (D-Arg6, Trp7, Leu8, Pro9Net)-LH-RH and 10 mg of domperidone (ovaprim), aromatase inhibitors and oytocin. Females Torsoro size 750-800 grams / fish, injected with oodev 0 ml, 0.5 ml oodev, oodev 1 ml, 1.5 ml oodev for induction of maturation. Fish injected every week for 5 weeks. Furthermore, female of Torsoro which is maturating gonads were injected with a combination of hormones that is ovaprim 0.5 ml / kg of fish, ovaprim 0.25 ml / kg of fish + HCG 500 IU / kg fish, ovaprim 0.25 ml / kg + 0.25 mg AI / kg; AI 0.50 mg / kg + 0.5 IU oxytocin (spawnprim) for final gonadal maturation and spawning of fish. The results showed that the injection of 1 ml Oodev give the best results in inducing gonadal maturation among other treatments. Injection with 1 ml oodev can induce the fish to mature gonads as much as 60%, with higher levels of estradiol-17ß as much as 102.12 ± 21.6 ng / ml, egg diameter of 3 mm. The best results showed that ovulation induction treatment combination of AI 0.50 mg/kg + 0.5 IU oxytocin (spawnprime) has a latency period of the fastest in stimulating ovulation 17.5 ± 0.52 h; fertilization rate of 96.60 ± 0.12%; hatching rate 81.05 ± 0.19%, and the survival rate of larvae reached 98.88 ± 0.41%. The results indicate that AI 0.50 mg / kg + 0.5 IU oxytocin (spawnprime) is the best hormone combination in inducing ovulation and spawning to semi-natural (spawning without stripping) on Torsoro. Induction of maturation of the gonads can be done by injecting Torsoro with Oodev that can induce axis hypothalamus-pituitary-gonads for vitellogenesis process through increased plasma estradiol that causes gonadal maturation in female fish. whereas, Spawnprim able to induce more effective for the final maturation of the gonads, which includes ovulation and spawning and reproductive performance are better than the results obtained ovaprim. Spawnprim also able to induce spawning reflex so that the fish can spawn with a semi-natural way (without stripping). The success in the induction of maturation by using Oodev, and also in the induction of ovulation and spawning by using Spawnprim, provide great opportunities to increase production of seed in artificial breeding Torsoro.
