Judul: The Sustainability Management of Djuanda Grand Forest Park in Bandung in West Java Province
Abstrak: Taman Hutan Raya Djuanda, yang ditetapkan pada tahun 1985 melalui Keputusan Presiden Republik Indonesia No. 3, merupakan Taman Hutan Raya pertama di Indonesia. Luas total Taman Hutan Raya Djuanda adalah 528.393 hektar, merupakan taman hutan raya terluas di Provinsi Jawa Barat. Kondisi alam Taman Hutan Raya Ir. H Djuanda mendukung pemanfaatan wisata alam dan fasilitasnya untuk mengembangkan pendidikan lingkungan. Fokus dari penelitian ini adalah untuk menilai keberlanjutan pengelolaan Taman Hutan Raya Djuanda terkait dengan empat pilar keberlanjutan yaitu ekologi, ekonomi, sosial budaya dan kelembagaan. Penelitian ini dilakukan pada bulan September hingga November 2023. Penilaian status keberlanjutan dilakukan dengan menggunakan metode Multi-Dimensional Scaling (MDS). Hasil dari penelitian ini menunjukkan bahwa nilai dimensi ekologi sebesar 57,99% (seluruhnya berkelanjutan), nilai dimensi ekonomi sebesar 74,20% (seluruhnya berkelanjutan), nilai dimensi sosial budaya sebesar 32,48% (kurang berkelanjutan), dan nilai dimensi kelembagaan sebesar 52,80% (seluruhnya berkelanjutan). Nilai keseluruhan status keberlanjutan Taman Hutan Raya Djuanda adalah 54,37% (seluruhnya berkelanjutan). Dimensi sosial budaya menunjukkan nilai terendah dan tergolong kurang lestari, sedangkan dimensi ekonomi menunjukkan nilai tertinggi. Berdasarkan analisis SWOT, untuk faktor internal menunjukan indeks posisi 1.53 (dengan rincian kekuatan 2.00 dan kelemahan 0.47), sedangkan untuk faktor eksternal menunjukan indeks posisi 1.00 (dengan rincian peluang 1.54 dan ancaman 0.54). Analisis tersebut menunjukan bahwa titik koordinat internal dan eksternal berada di titik positif atau kuadran I, sehingga strategi pengembangan yaitu mengoptimalkan kekuatan untuk memanfaatkan peluang. Hasil penelitian merekomendasikan 3 strategi utama pengelolaan yaitu, (1) mengoptimalkan tahura sebagai kawasan konservasi, (2) meningkatkan daya tarik wisata, dan (3) meningkatkan pemberdayaan masyarakat, Djuanda Grand Forest Park, established in 1985 by Decree No. 3 of the President of the Republic of Indonesia, is the first Grand Forest Park in Indonesia. The total area of Djuanda Grand Forest Park is 528,393 hectares, the largest grand forest park in West Java Province. Natural conditions of the Grand Forest Park Ir. H Djuanda supports using natural tourism and facilities to develop environmental education. The focus of this study is to assess the sustainability of the Djuanda Grand Forest Park management in relation to the following four pillars of sustainability: ecological, economic, sociocultural, and institutional. This research was conducted from September to November 2023. The assessment of sustainability status was conducted utilizing the Multi-Dimensional Scaling (MDS) method. The results of this research show that the ecological dimension value is 57,99% (entirely sustainable), the economic dimension value is 74,20% (entirely sustainable), the sociocultural dimension value is 32,48% (less sustainable), and the institutional dimension value is 52,80% (entirely sustainable). The overall value of the sustainability status of the Djuanda Grand Forest Park was 54,37% (entirely sustainable). The socio-cultural dimension exhibits the lowest value and is classified as less sustainable, whereas the economic dimension demonstrates the highest value and is classified as entirely sustainable. The results of the SWOT analysis indicate that the internal factors have a position index of 1.53, with strengths of 2.00 and weaknesses of 0.47. and the external factors have a position index of 1.00, with opportunities of 1.54 and threats of 0.54. The results indicate that both the internal and external coordinates are in the positive quadrant I. Consequently,

Judul: Analysis of Economic Valuation and the Impact of COVID-19 Pandemic Towards the Visits Level of Ir. H. Djuanda Bandung Grand Forest Park
Abstrak: Perubahan iklim yang dipicu oleh pemanasan global merupakan permasalahan lingkungan yang menjadi perhatian penting dunia. Penyumbang gas karbon dioksida penyebab pemanasan global salah satunya merupakan wilayah perkotaan. Kota Bandung sebagai kota yang memiliki daya tarik kunjungan wisata lokal dan mancanegara yang tinggi berimplikasi pada menurunnya kualitas lingkungan. Salah satu upaya untuk mengatasi hal ini adalah membangun dan merevitalisasi RTH yaitu Taman Hutan Raya Ir. H Djuanda Bandung. Tingginya ancaman yang ada dan potensi pemanfaatan Tahura Bandung sebagai area ekowisata perlu dijaga dan dilestarikan oleh masyarakat maupun pemerintah. Penelitian ini bertujuan untuk 1) menganalisis persepsi pengunjung terhadap keberadaan Taman Hutan Raya Ir. H. Djuanda Bandung; 2) menganalisis persepsi pengunjung terhadap COVID-19; 3) menganalisis pengaruh pandemi COVID-19 terhadap tingkat kunjungan Taman Hutan Raya Ir. H. Djuanda Bandung; dan 4) mengestimasi besarnya nilai guna tidak langsung dan nilai keberadaan Taman Hutan Raya Ir. H. Djuanda Bandung. Metode yang digunakan adalah skala Likert, Pendekatan harga pasar, Benefit Transfer, dan Contigent Valuation Method. Selama pandemi COVID-19 pengunjung memberikan penilaian yang baik terhadap kawasan Taman Hutan Raya Ir. H. Djuanda Bandung. Pengunjung sepakat bahwa COVID-19 adalah virus berbahaya. Pandemi COVID-19 terbukti menyebabkan peningkatan tingkat kunjungan dikarenakan perubahan persepsi berwisata masyarakat. Total nilai ekonomi tidak langsung di Taman Hutan Raya Ir. H. Djuanda Bandung adalah sebesar Rp 28.232.524.275., Climate change triggered by global warming is an environmental problem that has become an important concern for the world. One of the contributors to carbon dioxide gas that causes global warming in urban areas. Bandung as a city that has attracted local and foreign tourist visits has implications on degrading the environmental quality. One of the efforts to overcome this is to build and revitalize green open space, namely Ir. H Djuanda Bandung Grand Forest Park. The high threat that exists and the potential use of Ir. H. Djuanda Bandung Grand Forest Park as an ecotourism area needs to be maintained and preserved by the community and the government. This study aims to 1) analyze visitor perceptions of the existence of Ir. H. Djuanda Bandung Grand Forest Park; 2) analyze visitors' perceptions of COVID-19; 3) analyze the effect of the COVID-19 pandemic on the level of visits to the Ir. H. Djuanda Bandung Grand Forest Park; and 4) estimate the magnitude of the indirect use value and existence value of Ir. H. Djuanda Bandung Grand Forest Park. The methods used are the Likert scale, market price approach, Benefit Transfer, and Contingent Valuation Method. During the COVID-19 pandemic, visitors gave a good assessment of the Ir. H. Djuanda Bandung Grand Forest Park. Visitors agree that COVID-19 is a dangerous virus. The COVID-19 pandemic has proven to have caused an increase in visit rates due to changes in people's perceptions of tourism. The total indirect economic value in Ir. H.

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.
