The diversity of mangrove vegetation is a community that has different characteristics from other communities. Diversity is an important component in mangrove management, but so far the availability of data related to mangroves is still very minimal, including those related to the species diversity of mangrove forest vegetation in the region. This study aims to obtain data on species diversity of vegetation found in the mangrove forest area of Dusun Besar Village, Pulau Maya District, Kayong Utara Regency. Method used was a combination of path and plot method, and the determination of the location and research path location were carried out using purposive sampling. The results of observation and data analysis showed that the dominant vegetation species with the highest importance value index (INP) for seedlings, saplings and trees was the Avicennia marina, namely the INP value of seedlings 37.04%, the INP values of sapling 65.24%, and the value of INP a tree rate of 65. Based on the results of the most dominant analysis found the species of  Avicennia marina with a value of C = 0.03430 for seedling, C = 0.04729 for sapling, and C = 0.04736 for tree level. The diversity of mangrove forest vegetation species in Dusun Besar Village for seedlings, saplings and trees is low because it has an H 'value <1, and the abundance of mangrove vegetation species was not evenly distributed in each forest area because it only has an e value <1.Keywords: Dusun Besar Village, Mangrove Forest, Species Diversity

Kecukupan gizi ibu hamil ditentukan oleh kenaikan berat badan ibu yang juga akan mendukung kenaikan berat badan janin serta kecepatan janin mensintesis jaringan. Pencatatan hasil berat badan pada setiap kunjungan ibu hamil bermanfaat untuk mengetahui kesejahteraan janin yang ada di dalam kandungan ibu. Pengukuran Tinggi Fundus Uteri (TFU) menjadi titik awal evaluasi pertumbuhan janin. Taksiran berat janin berguna untuk memantau pertumbuhan janin dalam rahim, sehingga diharapkan dapat mendeteksi dini kemungkinan terjadinya pertumbuhan janin yang abnormal. Tujuan penelitian Menganalisis hubungan antara kenaikan berat badan ibu hamil dengan taksiran berat janin di RBG Zakat Surabaya. Sampel berjumlah 25 ibu adalah ibu hamil trimester 3 yang datang berkunjung ke klinik RBG Zakat Surabaya selama bulan Mei-Agustus 2019. Tehnik pengambilan sample menggunakan teknik purposive sampling. Analisis data menggunakan chi-square. Hasil penelitian Berdasarkan hasil uji statistic dengan chi-square di dapatkan hasil perhitungan menunjukkan signifikansi (α) = 0,396. Dengan asumsi jika ρ <0,05 Ho Ditolak maka ada hubungan antara kenaikan berat badan ibu dengan taksiran berat badan janin.The nutritional adequacy of pregnant women is determined by the increase in maternal weight, which will also support the increase in fetal weight, and the rate at which the fetus synthesizes tissue. Recording weight results at every visit of pregnant women is useful to know the welfare of the fetus in the mother's womb. Uterine Fundus Height Measurement (TFU) is the starting point for evaluating fetal growth. Estimated fetal weight is useful for monitoring fetal growth in the uterus, so it is expected to detect early the possibility of abnormal fetal growth. Research Objectives To analyze the relationship between weight gain of pregnant women and fetal weight estimates in RBG Zakat Surabaya. The sample of 25 mothers was 3rd trimester pregnant women who came to visit the Zakat Surabaya RBG clinic during May-August 2019. The sampling technique used purposive sampling technique. Data analysis using chi-square. Results of the study Based on the results of the statistical test with chi-square obtained the calculation results showed significance (α) = 0.396. Assuming if ρ <0.05 Ho is rejected then there is a relationship between maternal weight gain and estimated fetal weight.

Aktivitas penangkapan lebih (over fishing), penggunaan alat tangkap yang tidak ramah lingkungan, dan perubahan kondisi lingkungan perairan menyebabkan kelestarian ikan belida (Chitala lopis) menjadi terancam. Untuk itu, diperlukan upaya konservasi yang tepat untuk melestarikan ikan ini. Tahap awal adalah melalui penelitian morfologi. Tujuan penelitian adalah mengidentifikasi keragaman jenis ikan belida di Sungai Tulang Bawang (Lampung), Kampar (Riau), dan Kapuas (Kalimantan Barat) melalui variasi bentuk tubuh dan karakter morfologi pembeda. Penentuan lokasi pengambilan contoh dilakukan secara purposive sampling. Untuk setiap spesies pengambilan contoh per lokasi berkisar antara 10 sampai dengan 30 spesimen. Contoh ditandai (tagging) dituliskan kode spesimen dan lokasi kemudian diawetkan dengan direndam larutan alkohol 75%. Pengukuran spesimen dengan digital kaliper di sisi tubuh sebelah kiri, pada 28 karakter morfologi. Data yang diperoleh distandarisasi, disajikan dalam % SL dan % HL yang merupakan subyek principal component analysis menggunakan Statistik 6.0. Tahap ke-2, menggunakan analysis diskriminan untuk mengisolasi ke tipe spesimen tadi menjadi kelompok yang terpisah, melihat karakter morfologi dominan (factor score coefficient) akhirnya hanya 1 karakter yang paling dominan. Terdapat 3 kelompok ikan belida yang memperlihatkan penampilan morfologi yang berbeda, dari ke-3 lokasi yang diamati. Pembeda ke-3 kelompok ikan belida di 3 sungai tersebut adalah peduncle length (tinggi punguk) (% HL) dan mouth width (lebar mulut) (% SL). Over fishing activities, implementation of unfriendly environmental gears and altered aquatic environment condition have endangered the feather fish (Chitala lopis). Therefore appropriate conservation efforts will be needed and research on morphology variance can be the starting point. The objective of research is to indentify the diversity of feather fish in Tulang Bawang (Lampung), Kampar (Riau), and Kapuas (Kalimantan Barat) rivers through body shape variations and it’s main morphology characters. Sampling station were chosen based on purposive sampling. Whatever possible, the number of samples range between 10 to 30 in every station sampling. Samples were tagged with specimen code and location, and then preserve using alcohol 75%. Measurements were made manually using dial calipers correct to tenth milimetre. Measurements were made on the left side of body, 28 point to point measurements. These characters were standardized, perform in % SL and % HL subject to principal component analysis using Statistica 6.0. Futher analysis using discriminant analysis to isolate 3 type specimens, find out the dominant characters, and finally see the most dominance characters. There are 3 groups of feather fish’s that performed different morphology characters from the sampling site, where as peduncle length (% HL) and mouth width (% SL) were the dominance characters.

This study was undertaken with the intention of assessing abundance, species diversity, and distribution of medium and large diurnal mammals at the Humbo Community Based Forest Area, Ethiopia. The study area was stratified into three major habitats based on the vegetation cover of the area, such as riverine forest, bushland, and open grassland. The study in each vegetation type was surveyed using the transect method. It was conducted on foot along a randomly selected transect line. A total of eight large and medium mammalian species were recorded. The species recorded were Papio anubis, Sylvicapra grimmia, Tragelaphus scriptus, Chlorocebus pygerythrus, Tragelaphus strepsiceros, Lepus fagani, Phacochorus ethiopicus, and Panthera leo. During the survey, the leading order recorded was Artiodactyla followed by Primates. In terms of relative abundance, Anubis baboon (28.4% and 28.1%) and common duiker (19.4% and 11.4%) were the most abundant species, while warthog (12.1% and 8.9%) and lion (0.7% and 0.4%) were the least abundant during the wet and dry seasons, respectively. The highest number of mammalian species were distributed in bushland habitat during both wet (n = 7) and dry (n = 7) seasons. The highest Shannon-winner diversity index and evenness were obtained in the bushland habitat (1.70 and 2.21) during wet and dry seasons, respectively. Though the forest is the living place for various wild mammalian species, the conservation measures of the local community should also consider those species in line with the efforts that have been done on forest management practices.
