Abstract

Shark liver oil which becomes the main product for groups of fisherman in Cilacap was produced for traditional food suplement as health product which contains squalen. But the fishermen who processed did not pay attention to the process how to get the shark liver oil stuff so the squalen product could not be guaranted yet as health product. The research aim was to improve the squalen-degree quality of shark liver oil organoleptically. This research was an experimental research. Shark liver oil of bottle-type shark was processed by using a tool which was planned to produce it. The result was analyzed quantitatively to get squalen degree then it was compared to the squalen standard product in the market. The other quality aspects were the physical performance and its organolepty especially of the smell which caused problem. Shark liver oil product of this research was higher than that of standard product in the market and more qualified organoleptically because of the appropriate technology which was applied in its production. The comparison of squalen degree of this research comparing to the standard product in the market is 141 to 191 times bigger. The technology in this research used principle heating of perfect black thing producing more constantly heat in which the heat caused the oil out of shark liver organ. After the oil put into the container in that equipment, the oil was passed or refined using zeolite stone that absorbed substances that were undesirable. Absorbent chemical characteristic of this zeolite stone that would absorb undesirable subtances from the production process of shark liver oil so unpleasant or fishy smell of the oil would be reduced when compared to traditional production processes that relied on more stable direct sun heating without being filtered or refined with zeolite stone. This instrument produced more stable heating process and conditioned the process in the clean room so it could minimaze the contamination from outside. The characteristics of zeolite stone as an absorbent could absorb the undesirable substances like amoniac, so unpleasant smell could be reduced. Keywords: Squalen, shark liver oil, cilacap

Abstract

Pulau Sulawesi sangat rawan akan terjadinya gempabumi. Hal ini disebabkan oleh bertemunya tiga lempeng tektonik, yakni Lempeng Eurasia, Lempeng Filipina, dan Lempeng Indo-Australia. Di Sulawesi bagian utara juga terdapat lempeng mikro yakni Lempeng Laut Sulawesi, akibat dari pergerakan Lempeng Laut Sulawesi tersebut maka terbentuklah zona subduksi atau zona penunjaman. Zona subduksi pada Lempeng Laut Sulawesi tersebut yang dikenal dengan nama Megathrust Sulawesi Utara. Jika terjadi gempabumi dengan magnitudo yang sangat besar terjadi di Zona Megathrust Sulawesi Utara yang berpotensi terjadinya tsunami, maka perlu dibuat estimasi ancaman tsunami dengan menggunakan TOAST untuk mengetahui permodelan simulasi tsunami yang menghasilkan informasi-informasi penting seperti waktu tiba tsunami, lokasi-lokasi yang berpotensi tsunami dan ketinggian maksimum tsunami akan terjadi sebagai upaya mitigasi bencana. Kemampuan seluruh komponen masyarakat dan pemerintah daerah sangat diperlukan untuk membentuk resiliensi masyarakat yang berpotensi terdampak, khususnya dalam menghadapi ancaman bencana tsunami di Zona Megathrust Sulawesi Utara. Dengan demikian, risiko bencana tersebut dapat dikurangi atau ditekan.

Abstract

Gempabumi merupakan fenomena alam yang tidak dapat dihindari, dan tidak dapat dicegah. Gempabumi hingga saat ini belum dapat diprediksi secara akurat meskipun telah banyak penelitian mengenai prekursor gempabumi. Oleh karena itu, untuk mengurangi risiko yang ditimbulkan oleh ancaman gempabumi dibutuhkan sistem info gempabumi dan peringatan dini tsunami yang cepat dan akurat. Kejadian gempabumi yang terjadi pada tanggal 02 Agustus 2019 tepatnya pukul 19:03:21 WIB dengan kekuatan (magnitudo) 7,4 yang berpusat di laut pada arah 147 km BaratDaya Sumur Provinsi Banten, dan memiliki kedalaman (hiposenter) 10 km telah membuktikan bahwa zona megathrust selat sunda merupakan daerah seismik yang aktif. Dengan adanya kejadian gempabumi tersebut, Indonesia Tsunami Early Warning System (InaTEWS) langsung merespon dengan mengeluarkan peringatan dini tsunami 1 dengan waktu pengiriman informasi kurang dari 4 menit setelah gempabumi terjadi. Peringatan dini tsunami yang dinyatakan berakhir (peringatan dini tsunami 4) setelah 2 jam 31 menit dari kejadian gempabumi berdasarkan konfirmasi yang didapat dari data-data tide gauge yang lokasi berada di sekitar pusat gempabumi. Dengan cepatnya informasi peringatan dini yang diberikan oleh InaTEWS kepada pemangku kepentingan dan masyarakat setelah kejadian gempabumi tersebut merupakan salah satu bentuk implementasi dari ketahanan nasional dengan tujuan untuk mewujudkan masyarakat yang tangguh bencana sesuai dengan teori panca daya tangguh.
