Judul: Pemodelan karakteristik kimia air di Teluk Jakarta dan hubungannya dengan pembangunan giant sea wall
Abstrak: Giant Sea Wall will be built in the Bay of Jakarta. Intervention of reclamation Giant Sea Wall will lead to changes in hydro oceanographic patterns that will affect the distribution pattern of fertility in Jakarta Bay. Changes in distribution patterns can be simulated with numerical models approach Biogeochemical ROMS (Regional Ocean Modeling System) which based on four variables NPZD (nutrients, plankton, zooplankton and detritus). This study aimed to compare the biogeochemical processes that occur in the Bay of Jakarta in relation with intervention construction of Giant Sea Wall seasonally in the Bay of Jakarta. Model validation of nitrate with field data showed a high correlation when the first transitional seasons (r=0.9) and validation of chlorophyll-a with image modis satelit 2005-2015 showed a high correlation (r=0.8). Distribution pattern of NPZD was influenced by current circulation patterns. Giant Sea Wall intervention led to flow into the bay becomes blocked causing the inflow into the canal of reclamation and turn on land reclamation. Passive tracer movement of tracer distribution pattern of the Ciliwung River is affected by current flow and dispersed flow entering canal of reclamation and tend to accumulate around the canal. The influence of input Ciliwung River discharge into Jakarta Bay cause an increade the concentration of nitrat exception of all the variabels, especially dissolved oxgen has lower concentration. Variables component of nitrate, phytoplankton, zooplankton, and detritus in Jakarta Bay seems to correlation if nitrate concentration increase while the concentration of phytoplankton has decreased due to higher concentration of zooplankton grazing activities that lead to increased concentration of detritus.

Judul: Sebaran Konsentrasi Fosfat (PO4-P) dan Nitrat (NO3-N) sebagai Indikator Kesuburan Perairan di Teluk Jakarta
Abstrak: Teluk Jakarta terletak di pantai utara Pulau Jawa merupakan muara bagi 13 sungai besar di Jakarta, Bogor, Depok, Tangerang, dan Bekasi. Berbagai aktivitas yang melibatkan pemanfaatan perairan baik teluk maupun sungai dapat menyebabkan penurunan kualitas perairan dan pengayaan nutrien. Salah satu akibat pengayaan nutrien yaitu peningkatan nutrien seperti fosfat dan nitrat yang dapat memengaruhi produktivitas perairan. Penelitian ini bertujuan menganalisis sebaran konsentrasi fosfat dan nitrat di Teluk Jakarta secara spasial dan temporal. Pemantauan kualitas air dilakukan antara tahun 2012 hingga 2019 sebanyak delapan kali pengamatan dari 23 stasiun. Penentuan 23 stasiun berdasarkan keterwakilan wilayah Teluk Jakarta. Berdasarkan kandungan fosfat dan nitrat, perairan Teluk Jakarta terrmasuk subur. Pola sebaran spasial fosfat dan nitrat konsentrasinya lebih tinggi di sekitar pantai dan semakin rendah seiring mendekati mulut teluk. Secara temporal, konsentrasi fosfat dan nitrat menunjukkan perbedaan yang signifikan cenderung meningkat dari tahun ke tahun., Jakarta Bay is located on the north coast of Java Island and is the mouth of 13 major rivers in Jakarta, Bogor, Depok, Tangerang, and Bekasi. Various activities that involve the use of waters, both bays and rivers, can cause a decrease in water quality and nutrient enrichment. One result of nutrient enrichment is an increase in nutrients such as phosphate and nitrate which can affect water productivity. This study aims to analyze the spatial and temporal distribution of phosphate and nitrate concentrations in Jakarta Bay. Water quality monitoring was carried out between 2012 and 2019 in eight observations from 23 stations. Map of 23 stations based on the representativeness of the Jakarta Bay area. Based on the content of phosphate and nitrate, the waters of Jakarta Bay are considered fertile. The pattern of spatial distribution of phosphate and nitrate concentrations is higher around the coast and lower as they approach the mouth of the bay. Temporally, the concentrations of phosphate and nitrate showed significant differences which tended to increase from year to year.

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.
