Judul: Keanekaragaman dan KeIimpahan Komunitas Makrozoobenthos pada Hutan Mangrove Hasil Rehabilitasi di Taman Hutan Raya Ngurah Rai, Bali
Abstrak: Saat ini luas mangrove telah mengalami degradasi karena berbagai sebab dan permasalahan yang dihadapinya. Degradasi hutan mangrove Indonesia terjadi akibat pemanfaatan yang kurang tepat atau mengalami perubahan fungsi, misalnya menjadi areal pertambakan udang. Hal tersebut terjadi karena pada beberapa dekade ini, pemanfaatan mangrove terus meningkat bukan saja dari segi pemanfaatan lahannya saja tetapi juga dari segi pemanfaatan kayu, baik seeara tradisional maupun komersial. Pengaruh yang ditimbulkannya sangat luas apabiJa ditinjau dari aspek sosial, ekonomi, dan ekologi.

Judul: Analysis of Community Structure Association Biota in the Mangrove Ecosystem Rehabilitation Area in Tangerang Regency
Abstrak: Wilayah pesisir Kabupaten Tangerang memiliki kawasan mangrove yang sedang dalam proses rehabilitasi. Makrozoobentos merupakan biota asosiasi pada kawasan ekosistem mangrove. Penelitian ini bertujuan untuk menganalisis sebaran makrozoobentos dan komponen utama yang mempengaruhi keberadaan makrozoobentos pada ekosistem mangrove di pesisir Kabupaten Tangerang. Penelitian dilaksanakan pada bulan Februari hingga Maret 2022 di tiga desa, yaitu Desa Ketapang, Desa Patramanggala, dan Desa Tanjung Pasir, Kabupaten Tangerang. Analisis data terdiri atas penentuan stasiun pengambilan contoh, pengolahan data vegetasi mangrove, pengolahan data makrozoobentos, dan penutupan kanopi menggunakan aplikasi ImageJ. Hasil analisis komponen utama menunjukkan sebaran makrozoobentos di pesisir Kabupaten Tangerang di tiga desa dipengaruhi oleh suhu tanah, pH air, penutupan mangrove, tipe substrat, dan jenis mangrove. Komposisi jenis makrozoobentos di Desa Ketapang dan Tanjung Pasir didominasi oleh kelas Gastropoda, serta di Desa Patramanggala didominasi kelas Bivalvia., The coastal area of Tangerang Regency has a mangrove area that is in the process of being rehabilitated. Macrozoobenthos is association biota in the mangrove ecosystem area. This study aims to analyze the distribution of macrozoobenthos and the main components that affect the presence of macrozoobenthos in the mangrove ecosystem on the coast of Tangerang Regency. The research was conducted from February until March 2022 in three villages, Ketapang Village, Patramangala Village, and Tanjung Pasir Village, Tangerang Regency. Data analysis consisted of determining sampling stations, processing mangrove vegetation data, processing macrozoobenthos data, and canopy closure using the ImageJ application. The results of the main component analysis showed that the distribution of macrozoobenthos on the coast of Tangerang Regency in three villages was influenced by soil temperature, water pH, mangrove cover, substrate type, and mangrove species. The composition of the macrozoobenthos species in the Ketapang and Tanjung Pasir villages was dominated by the Gastropod class, and in Patramanggala Village, it was dominated by the Bivalvia class.

Judul: The Leukocyte Profile of Pregnant Friesian Holstein Cows vaccinated with Escherichia coli K99 polivalen vaccine.
Abstrak: The objective of this experiment was to study the leukocyte profile of pregnant cows vaccinated with E.coli K99 polivalen vaccine. Three pregnant Friesian Holsteins cows were used in this experiment. Before the administration of vaccine, the cows were given a series of immunomodulator injection for three days. The vaccinations were administered three times at 8, 6, and 4 weeks before calving. Blood were drawn through jugular vein, first before the administration of vaccines, then weekly until calving. Based on the observation, it can be concluded that the administration of E.coli K99 polivalen vaccine in pregnant cows not affected the leukocyte profile.
