Judul: Climate Change Risk Assessment in Coastal Area of Jakarta (Study case: North Jakarta City)
Abstrak: Pesisir DKI Jakarta merupakan wilayah yang menjadi prioritas dalam aksi ketahanan iklim karena berpotensi mendapatkan ancaman bahaya dari laut dan daratan. Penilaian risiko perubahan iklim bertujuan memetakan wilayah berdasarkan tingkat risikonya terhadap ancaman bahaya iklim di masa depan yaitu, cekaman panas, hujan ekstrem, cekaman kekeringan dan banjir rob sekaligus memberikan rekomendasi aksi pada wilayah prioritas. Wilayah dengan kategori risiko sangat tinggi dipengaruhi oleh tingkat ancaman bahaya yang tinggi, profil wilayah yang mudah terpengaruhi oleh dampak buruk, kepadatan penduduk yang tinggi namun rendah pada kapasitas untuk merespon bahaya. Wilayah dengan tingkat risiko rendah memiliki ancaman bahaya rendah dan rendahnya potensi dampak buruk yang dapat dirasakan masyarakat, atau tingginya kapasitas kewilayahan dalam merespon dampak bahaya yang dapat meredam tingkat risiko pada ancaman bahaya tinggi. Lokasi berisiko tinggi paling banyak berada di Kecamatan Cilincing, Tanjung Priok, dan Koja sedangkan wilayah yang tidak terdapat risiko tinggi yaitu Kecamatan Kelapa Gading. Kecamatan dengan wilayah prioritas terbanyak berada di Kecamatan Cilincing, Penjaringan, dan Koja. Berdasarkan identifikasi terhadap indikator aksi yang perlu diintervensi dapat difokuskan pada sektor kesehatan, ekonomi, lingkungan dan infrastruktur, karena sebagian besar wilayah prioritas memiliki kekurangan pada sektor tersebut yang perlu diintervensi untuk menurunkan tingkat risiko., Coastal area of DKI Jakarta is a priority area in climate resilience action because it has the potential to experience hazard from the sea and land. Climate change risk assessment aims to map areas based on their risk level for future climate hazards, such as heat stress, extreme rainfall, drought and tidal floods, as well as providing recommendations for action in priority areas. Locations with a very high risk category are influenced by a high level of hazard, easily affected by adverse impacts, high population density but low capacity to respond to hazards. Locations with a low risk level have a low level of hazard and a low potential for adverse impacts that can be felt by the community, or a high regional capacity to respond the impact of hazard which can reduce the level of risk. The most high-risk locations are in Cilincing, Tanjung Priok and Koja Districts, while the areas where there is no high risk are Kelapa Gading District. The locations with the most priority areas are Cilincing, Penjaringan and Koja Districts. Based on the identification of indicators that need intervention on action, it can be focused on the health, economic, environmental and infrastructure sectors, because most priority areas have deficiencies in these sectors that need intervention to reduce the level of risk.

Judul: Isolasi dan purifikasi inhibitor RNA helikase virus hepatitis C dari bakteriosin bakteri asam laktat S34
Abstrak: Target molecular therapy is one of method to prevent hepatitis C virus which was developed recently. NS3 Helicase/RNA helicase hepatitis C virus inhibition using inhibitory peptide are target in molecular therapy. Bacteriocin are inhibitory peptides which can inhibit hepatitis C virus through inhibition of NS3 helicase. Bacteriocin is a peptide which is produced by lactic acid bacteria. The aim of this research were to isolate and to purify bacteriocin from S34 lactic acid bacteria which has high activity to inhibit RNA helicase of hepatitis C virus. S34 lactic acid bacteria were identified using 16S RNA amplification and DNA sequencing identification of S34 lactic acid bacteria was Lactobacillus plantarum WCFS1. The bacterial growth reached logaritmic phase at 7 hours and stationary phase at 10 hours. Bacteriocin were isolated and purified by ammonium sulphate precipitation with 80% saturation, gel filtration chromatography, and characterization of bacteriocin through molecular weight analysis and measured protein concentration. Bacteriocin from S34 lactic acid bacteria were included in 2nd class bacteriocin, had 64.20 % of inhibition against RNA helicase hepatitis C virus, had molecular weight about 1.7-4.2 kDa, and specific activity in the amount of 2.84 x 106 U/mg.
