Judul: Estimation of Vegetation Density Using NDVI and  Carbon Stock in the Core Zone of Gunung Halimun Salak National Park, Estimation of Vegetation Density Using NDVI and  Carbon Stock in the Core Zone of Gunung Halimun Salak National Park
Abstrak: Increasing concentrations of greenhouse gas emissions causes climate change and global warming. Gunung Halimun Salak National Park (GHSNP) potentially mitigate CO2 emissions change by increasing carbon stocks. This study aimed to estimate vegetation density using the Normalized Difference Vegetation Index (NDVI), biomass and aboveground carbon stocks, as well as to analyze the relationship of NDVI with vegetation diversity and carbon stocks in the core zone of GHSNP. The method used was vegetation analysis and carbon estimation using allometric and destructive testing for seedling and understory levels. The total plots were 15 (a plot size of 50 × 50 m). NDVI was categorized into three classes, specifically class 1 (0,147 – 0,276), class 2 (0,276 – 0,321), and class 3 (0,321 – 0,493). The core zone of GHSNP consists of 82 plant species from 53 families. The most families found were Euphorbiaceae, Lauraceae, Moraceae, Rubiaceae, and Urticaceae. The research location was dominated by african wood (Maesopsis eminii). The average biomass and carbon concentrations based on density class were 124,46 ton/ha dan 58,50 ton/ha, respectively. Carbon concentration strongly correlated with basal area (r = 68,9%). NDVI values had a positive correlation and can be used to estimate species abundance, tree density, Shannon-Wiener index, LBDS, and carbon concentration.

Judul: Correlation of Carbon Stocks with Vegetation Density Based on NDVI in the Rehabilitation Zone of Gunung Halimun Salak National Park
Abstrak: Kenaikan konsentrasi Gas Rumah Kaca (GRK) dan emisi karbon merupakan faktor yang berkontribusi besar terhadap perubahan iklim global. Taman Nasional Gunung Halimun Salak (TNGHS) merupakan salah satu kawasan konservasi yang berpotensi dalam mengurangi dampak perubahan iklim melalui peningkatan cadangan karbon. Penelitian ini bertujuan untuk menganalisis kerapatan dan tingkat keanekaragaman vegetasi, menduga potensi biomassa dan cadangan karbon tersimpan di atas permukaan tanah, serta menganalisis hubungan antara nilai NDVI dengan jumlah jenis, kerapatan pohon, keanekaragaman vegetasi, luas bidang dasar (LBDS), dan konsentrasi karbon. Metode yang digunakan analisis vegetasi, sedangkan pendugaan karbon menggunakan pendekatan alometrik dan destruktif untuk tingkat semai dan tumbuhan bawah. Plot yang dibangun berukuran 50 m × 50 m sebanyak 14 plot. Berdasarkan hasil analisis NDVI, kelas kerapatan terbagi menjadi kelas 1 (0,321–0,485), dan kelas 2 (0,485–0,746). Komposisi vegetasi di zona rehabilitasi TNGHS terdiri atas 103 jenis tumbuhan dan didominasi oleh rasamala (Altingia excelsa). Rata-rata biomassa dan konsentrasi karbon berdasarkan kelas kerapatan yang diperoleh masing-masing sebesar 296,55 ton/ha dan 139,38 ton/ha. Konsentrasi karbon memiliki korelasi kuat dengan LBDS (r = 95,5%). Nilai NDVI berkorelasi paling tinggi dengan kerapatan pohon per hektar., Increasing greenhouse gas concentrations and carbon emissions contribute greatly to global climate change. Gunung Halimun Salak National Park (GHSNP) is a conservation area with the potential to reduce the impact of climate change through increasing carbonreserves. This research aimeds to analyze the vegetation density and diversity, estimate the potential for biomass and carbon reserves and analyze the relationship between NDVI values and number of species, tree density, vegetation diversity, basal area (LBDS), and carbon concentration. The method used was vegetation analysis, while carbon estimation used an allometric for stake, pole and tree levels. Destructive approach for the seedling and understory levels. The plots that were built were 14 plots measuring 50 m × 50 m. Based on the results of NDVI analysis, density classes are divided into class 1 (0.321–0.485), and class 2 (0.485–0.746). The vegetation composition in the TNGHS rehabilitation zone consists of 103 plant species and is dominated by rasamala (Altingia excelsa). The average biomass and carbon concentration based on density class obtained were 296,55 tonnes/ha and 139,38 tonnes/ha respectively. Carbon concentration has a strong correlation with LBDS (r = 95.5%). NDVI values correlate higher with tree density per hectare variable than other variables.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
