2020 KECENDERUNGAN NAIKNYA SUHU PERMUKAAN LAUT DAN RESILIENSI KARANG SETELAH KEJADIAN PEMUTIHAN KARANG 2010 DAN 2016 DI TAMAN WISATA PERAIRAN (TWP) PULAU PIEH, PADANG, SUMATRA BARAT Fasmi Ahmad,Sam Wouthuyzen Kejadian pemutihan karang (coral bleaching) telah melanda hampir seluruh perairan Indonesia sedikitnya 4 kali antara tahun 1982-2016. Dua kejadian terbaru (2010 dan 2016) telah dibahas mendalam, namun belum ada kajian rinci pada suatu lokasi yang spesifik, seperti di Taman Wisata Perairan (TWP) Pulau Pieh, perairan Padang, Sumatra Barat yang dipengaruhi oleh massa air Samudra Hindia. Tulisan ini bertujuan mengkaji kecenderungan naiknya suhu permukaan laut (SPL) pada kejadian pemutihan karang 2010 dan 2016 dan resiliensi karang setelah kejadian tersebut. Pada kajian ini data SPL jangka panjang hasil pemindaian citra satelit Aqua MODIS digunakan secara intensif. Hasil kajian menunjukkan bahwa SPL rata-rata… Lihat
2020 Multiplicity dependence of light (anti-)nuclei production in p-Pb collisions at sqrt(sNN) = 5.02 TeV ALICE Collaboration, Suharyo Sumowidagdo The measurement of the deuteron and anti-deuteron production in the rapidity range −1<y<0 as a function of transverse momentum and event multiplicity in p–Pb collisions at sNN = 5.02 TeV is presented. (Anti-)deuterons are identified via their specific energy loss dE/dx and via their time-of-flight. Their production in p–Pb collisions is compared to pp and Pb–Pb collisions and is discussed within the context of thermal and coalescence models. The ratio of integrated yields of deuterons to protons (d/p) shows a significant increase as a function of the charged-particle multiplicity of the event starting from values similar to those observed in… Lihat
2020 pemanfaatn serangga akuatik untuk investigasi forensik Merry Christina Simanjuntak,Jojok Sudarso Serangga akuatik merupakan komponen penting dalam proses dekomposisi materi organik kasar di ekosistem perairan dan sebagian besar termasuk dalam organisme makrozoobentos (Parmenter and Lamarra,1991). Kurang lebih 70-90% organisme makro-zoobentos yang ada termasuk dalam golongan serangga (Fenoglio et al.,2014). Peran dari hewan tersebut di perairan adalah sebagai dekomposer materi organik kasar untuk dirubah menjadi partikel organik halus (fine particulate organic matter/FPOM maupun ultra particulate organic matter/ UPOM). Sebagian besar penelitian tentang serangga akuatik ini lebih banyak difokuskan pada: interaksi antara mangsa-predator, fisiologi, dinamika trofik, kompetisi, dinamika populasi, pencemaran, parasitisme, taksonomi, tingkah laku, dan sebagainya (Merrit and Wallace,2010). Namun kajian mengenai peran… Lihat

2020 Platygobiopsis hadiatyae, a new species of deepwater gobiid from Indonesia (Teleostei, Gobiidae, Gobiinae) HK. Larson1; Z. Jaafar, TH. Hui & T. Peristiwady A new species of the gobiid genus Platygobiopsis Springer & Randall, 1992, is described based on a single specimen collected via dredge deployed at a depth range of 172 m and 182 m within the East Sunda Strait off Panaitan Island (Indonesia). The new species differs chieftly from congeners in having a scaleless (vs. scaled) chest and belly. A key to the four known species of Platygobiopsis is provided. Key words. Gobiidae, Gobiinae, Platygobiopsis, new species Lihat
2020 Diurnal Variation of the Water Quality Parameters in the Waste Stabilization Ponds (WSP) for Water Treatment of Integrated Multi-Trophic Aquaculture (IMTA) Ponds with Closed Re-Circulation System Nurul Setiadewi,Guruh Satria Ajie Organic wastes from Floating Fish Cage Aquaculture (FCA) activities have polluted many inland water bodies, from small reservoirs to major lakes, in Indonesia. It has become a national priority to restore ecosystem health in Lake Maninjau. The lake has suffered from the negative effects of approx. 17,000 units of FCA on its surface area. Response for a better FCA practices that would process its own waste before returning it back to the lake ecosystem has been proposed. FCA waste should be contained for then pumped into a wetland system for its water quality improvement. The proposed system consists of a… Lihat
2020 State Machine Implementation for Human Object Tracking using Combination of MobileNet, KCF Tracker, and HOG Features Fabiola Maria Teresa Reetno Kinasih , Christ Freben Dommaris Saragih , Carmadi Machbub , Pranoto Hidaya Rusmin , Lenni Yulianti Since the Viola and Jones' method on real-time face detection was proposed in 2001, numerous works for object detection, person recognition, and object tracking have been published by papers and journals. Each method has its strong points and drawbacks. That means that in a system which only employs a standalone method, we could only get either speed or accuracy. In this paper, we proposed a state-machine method to combine face recognition, face detection, and tracker to harness the tracker promptness while maintaining the ability to distinguish the person of interest with the other person and backgrounds, to overcome the limitations… Lihat
2020 Genetic characterization and phylogenetic study of Indonesian Indigenous Catfish based on Mitochondrial cytochrome B gene Dorothea Vera Megarani; Zahrah Prawita Andarini; Yura Dwi Risa B R Surbakti; Rini Widayanti Aim: This study aimed to determine the genetic characterization and phylogenetic structure of Indonesian indigenous catfish using cytochrome B (Cyt B) sequences. Materials and Methods: The genomes of 26 catfishes caught from nine rivers from nine different geographical locations around Indonesia were analyzed. The tissue isolation method was used to isolate the total genome of the fishes. Furthermore, polymerase chain reaction was done to amplify the mtDNA Cyt B using the CytBF and CytBR primers. Following sequencing, the analysis of genetic variation and the phylogenetic relationship was performed using MEGA version X software. Results: Cyt B gene sequencing attained a… Lihat
2020 Ahmadiyah and Islamic Revivalism in the Twentieth Century Java, Indonesia: A Neglected Contribution Ahmad Najib Burhani The existence of Ahmadiyah in Indonesian Islam has often been seen as a parasite. They have been considered heretical groups that politically felt as disturbing the hegemony of Sunni Islam and theologically defaming or insulting the doctrines and teachings of Islam. Consequently, the followers of Ahmadiyah often became a victim of religious radicalism; discriminated in a number of government regulations, displaced from their homes and villages, and even treated like stateless citizens. Contrary to this condition, Ahmadiyah were warmly welcome during the time of their arrival in the 1920s, and seemed to have strong influences on Muslim intelligentsia, particularly Dutch-educated… Lihat
2020 Species delimitation and systematics of the green pythons (Morelia viridis complex) of melanesia and Australia Amir Hamidy,Awal Riyanto,Daniel J.D. Natusch , Damien Esquerré, Jessica A. Lyons, Amir Hamidy, Alan R. Lemmon , Emily Moriarty Lemmon , Awal Riyanto, Scott Keogh , Stephen Donnellan Molecular data sets and the increasing use of integrative systematics is revealing cryptic diversity in a range of taxa – particularly in remote and poorly sampled landscapes like the island of New Guinea. Green pythons (Morelia viridis complex) are one of the most conspicuous elements of this island’s fauna, with large numbers taken from the wild to supply international demand for exotic pets. We test hypotheses about species boundaries in green pythons from across New Guinea and Australia with itochondrial genomes, 389 nuclear exons, and comprehensive assessment of morphological variation. Strong genetic structuring of green python populations and species delimitation… Lihat
