Teluk Bakau Village is one of the largest conservation areas of seagrass ecosystem located in Bintan Island. This research aim to study the distribution of species, seagrass coverage and seagrass density in Teluk Bakau Village. The research was conducted at two stations, Beralas Pasir Island and Teluk Bakau Village Beach. Seagrass data collections are computed using transect quadrat method. The results of this study show that there is total 8 species of seagrasses found in the conservation area of seagrass ecosystem in Teluk Bakau, namelu Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Cymodocea serulata, Halophila ovalis, Halophila minor, Syringodium isoetifolium and Halodule uninervis. The highest seagrass cover value was found at Beralas Pasir Island station about 47%, while in Teluk Bakau Village Beach station the seagrass coverage value was arround 29%. Based on these coverage value, the seagrass ecosystem in Teluk Bakau area fall in the category of medium conditon. The excistence of seagrass ecosystem in Teluk Bakau village is utilized by the community in small scale fisheries activity, therefore it is utmost important that its biodiversity and level of coverage are maintaned or even improved.

Tanah Putih Village has the potential for the development of Bali cattle because it has extensive grazing land and the majority of farmers raise Bali cattle. The aim of the study was to obtain data on the diversity and intensity of gastrointestinal endoparasitic infection in Balinese cattle with an extensive breeding system in Tanah Putih Village, Kupang Timur District, Kupang Regency, East Nusa Tenggara Province. Gastrointestinal endoparasitic diversity was identify using sedimentation and flotation methods while the intensity of endoparasitic infection was carried out using McMaster method, while data on the diversity and rates of gastrointestinal endoparasitic infection were analyzed descriptively. The results of the study on the diversity of gastrointestinal endoparasites found there are five types of nematode worm eggs namely Haemonchus contortus, Oesophagostomum radiatum, Strongyloides papillosus, Bunostomum phlebotomum, and Trichostrongylus axei. Factors that support the diversity of endoparasites are feed sources, livestock populations, and grazing rotation. The average number of worm eggs found based on the total eggs per gram of faeces for Haemonchus contortus as many as 100 eggs and the other four types of worm eggs amounted to 50 eggs. The average number of eggs indicates that endoparasitic infections in these animals fall into the mild intensity category, is influenced by season, feed source, and age of livestock. The five types of gastrointestinal endoparasites found namely Haemonchus contortus, Oesophagostomum radiatum, Strongyloides papillosus, Bunostomum phlebotomum, and Trichostrongylus axei.

To overcome the problem of iodine deficiency, administration of iodized salt, counseling of iodized food sources and goitrogenic food are very important. The goal is to change the consumption of iodized and goitrogenic food sources and consume the recommended iodized salt, so that iodine intake is fulfilled and urinary iodine excretion becomes normal. This study was an experimental research, using pre-test and post-test with control group design. The sample size was 60 students of elementary school, consisting of 30 students. students for the treatment group and 30 students for the control group. In the treatment group, the mothers of the students were given iodized salt to give to their children, provided counseling about food sources that are rich in iodine and which are goitrogenic. The parameters measured were the consumption of iodine, protein and urinary iodine excretion in the phase before and after being treated, with a span of time for 3 weeks. Data collection on nutrient consumption was done through recall once in 24 hours. The level of iodine in the urine was measured using spectrophotometry, and the consumption of goitrogenic sources was measured through observation at the time of recall. The data were analyzed using t-test. Based on the results of the study it can be concluded that in Sedau Village, Narmada District, West Lombok Regency; giving iodized salt, counseling about iodized and goitrogenic food sources to mothers who have children in primary school. Keywords: iodized salt; counseling; food sources of iodine; goitrogenic; excretion of urine iodine

Tuatuka Kabupaten Kupang merupakan Program Pengabdian Masyarakat yang bertujuan untuk meningkatkan pengetahuan dan keterampilan anggota mitra kelompok tani tentang model kemitraan proporsional dan manajemen penggemukan ternak babi dalam upaya meningkat produktifitas ternak babi. Kelompok tani Sehati menjadi mitra atas permintaan kelompok tani tersebut dan dengan mempertimbangkan bahwa usaha penggemukan ternak babi merupakan rutinitas yang dijalankan dalam keseharian mereka. Kegiatan beternak babi anggota kelompok tani tersebut selama ini masih bersifat tradisional dan penggunaan bibit dalam jumlah dan kualitas yang rendah, dengan menggunakan pakan limbah rumah tangga, modal yang terbatas, serta penjualan yang tidak menentu. Kondisi tersebut berdampak pada semangat beternak mereka yang pada akhirnya mempengaruhi keuntungan mereka dari ternak babi. Metode pelaksanaan kegiatan dilakukan melalui penyuluhan, diskusi, demonstrasi plot, pendampingan, serta monitoring dan evaluasi. Implementasi kegiatan dilakukan melalui diseminasi informasi model kemitraan proporsional, manajemen kesehatan, dan tata laksana penggemukan (kandang dan pakan). Hasil yang dicapai dari kegiatan adalah peningkatan pengetahuan, kesadaran, dan keterampilan anggota mitra dalam menerapkan model kemitraan proporsional serta manajemen penggemukan ternak babi
