Judul: Tunda Island Marine Tourism Development Strategy with Coastal Resources Natural Resources Approach, Serang Regency, Banten.
Abstrak: Tunda Island is a small island that has accessible resources, inaccessible resources, and environmental services that are potential for development in the marine and fisheries sector. Ecosystem environmental services are utilized in tourism activities with the concept of ecotourism. The development of ecotourism has been going on for decades worldwide, especially in tropical areas with coastal assets such as corals, mangroves and beaches. Information in the form of suitability studies and strategies for the use of mangrove ecosystems, coral reefs and beaches as objects of ecotourism needs to be examined to see if natural resources have not been used effectively and optimally as tourist objects. The suitability study needs to be accompanied by a study of each regional activity carrying capacity to maintain the sustainability of natural resources. The methods used in collecting ecological data are water passes for slope beaches, transect quadrat and spot check to identify mangrove, Underwater Photo Transect (UPT) for identifying coral reefs, and Underwater Visual Census (UVC) for identifying reef fish. The collection of economic data is carried out on tourists, while the collection of social data is carried out to several stakeholders organized both at the local community level, up to the province of Banten. To formulate the Tunda Island marine tourism development plan, it used spatial analysis, carrying capacity analysis, economic analysis, and strategy analysis are used using the Hierarchy Process Analysis (AHP). The tourism potential that can be developed is the potential for beach tourism, mangrove tourism potential, snorkeling tourism potential and diving tourism potential. The carrying capacity of beach tourism is 776 people/day, mangrove tourism is 80 people/day, snorkeling tours are 562 people/day and diving tours are 587 people/day. The economic value of willingness to pay by tourists or Willingness to Pay (WTP) is IDR 21 056 198 per year. The key stakeholders of Tunda Island marine tourism are Dinas Kelautan dan Perikanan (DKP) Banten Province and Kelompok Sadar Wisata (POKDARWIS) Tunda Island. The marine tourism development strategy of Tunda Island was arranged using AHP analysis. Developing the marine tourism strategy of Tunda Island was based on ecosystem management priorities by improving the ecosystem, considering carrying capacity, conducting rehabilitation, monitoring and evaluation of ecosystems, improving infrastructure facilities, increasing capacity and empowering communities, integrated management between stakeholders and improving facilities and infrastructure.

Judul: Ecotourism Development Strategy in the Dampier Strait Marine Conservation Area Southwest Papua Province
Abstrak: The Dampier Strait regional conservation area is one of the conservation areas included in the Raja Ampat Regency marine conservation area, which has high potential for developing tourism activities. The most important aspect in the use of natural resources for tourism purposes is their suitability to support tourism activities. The challenge faced is the difficulty if the potential for beach tourism, snorkeling and diving to be developed simultaneously The aim of this research is to determine areas for ecotourism and recommend appropriate locations. Data analysis is determining ecotourism areas using the Technique For Order Preference by Similarity to Ideal Solution (TOPSIS). TOPSIS is used because it is able to rank the selected alternatives that are closest to the positive ideal and furthest from the negative ideal solution. The criteria used are tourist carrying capacity, accommodation, accessibility, number of international tourists, number of domestic tourists and suitability area. The results of this TOPSIS analysis are that Sauwandarek, Marandanweser and Arborek are areas that can be used as an alternative areas for carrying out beach tourism, snorkeling and diving activities. Areas that can be developed into ecotourism activities are Yeben Kecil and Tanjung Putus., The Dampier Strait Regional Marine Conservation Area (KKPD) is one of the conservation areas included in the Raja Ampat Regency Marine Conservation Area which has high potential for developing ecotourism activities. The most important aspect of the use of natural resources for ecotourism purposes is the suitability that supports ecotourism activities. The challenge faced is the difficulty if the potential for beach tourism, snorkeling and diving are to be developed simultaneously. Therefore, it is important to have an ecotourism development strategy in conservation areas. This research aims to evaluate the suitability and carrying capacity, determine alternative areas for ecotourism activities, and formulate ecotourism management strategies in the Dampier Strait. The research was carried out in September 2021 in several areas in the Dampier Strait, namely Yeben Besar, Yeben Kecil, Tanjung Putus, Arborek, Friwen, Sauwandarek, Waiweser, Yenbekwan, Marandanweser, Yef Adoak, and Dayan. Activities carried out include collecting data on the suitability of beach tourism, snorkeling, and diving, as well as direct observations to determine alternative tourism areas and ecotourism management strategies. The research results show that not all research areas can be used for beach, snorkeling and coastal tourism activities. Dayan is very suitable for beach tourism, snorkeling and diving, because the area has suitable values for the three ecotourism activities. However, it is also necessary to know the carrying capacity of each region, so that the visitor capacity does not exceed the carrying capacity of the region. Based on calculations of carrying capacity for beach activities, snorkeling and diving, it shows that many visitors can carry out tourist activities in the area. The largest beach carrying capacity is at Sauwandarek at 68,976 visitors/year, the largest snorkeling capacity is at Waiweser at 2,712 visitors/year, and the largest diving carrying capacity is at Dayan at 190 visitors/year. Alternative areas obtained through the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) analysis are Sauwandarek, Marandanweser, and Arborek. The main strategy that

Judul: Leukemia pada kucing
Abstrak: Leukemia pada kucing adalah suatu penyakit yang sangat patogen, disebabkan oleh sejenis virus. Virus ini dikenal sebagai Feline Leukemia Virus atau FeLV. FeLV ini oleh beberapa ahli dikatakan hanya bersifat ganas pada hewan kucing. Penularannya bisa secara horizontal maupun congenital. Kucing pada semua tingkat umur dapat terserang oleh FeLV ini. Khusus pada bentuk "thymic leukemia", virus ini hanya menyerang anak-anak kucing berumur diba- wah 1 tahun. Kucing-kucing liar atau yang tidak terpeli- hara jarang sekali terinfeksi FeLV. Selain dari serangan virus FeLV itu sendiri, maka penyakit leukemia ini bisa disebabkan oleh beberapa fak- tor yang sudah ada dalam tubuh hewan dan sangat menunjang perkembangan penyakit ini, yaitu antara lain tumor, agen toksik, cedera oleh kecelakaan dan gangguan hemopoiesis. FeLV menyerang sel-sel darah dalam tubuh hewan se- hingga pembentukan darah berjalan tidak normal. Terlihat sel-sel darah yang belum dewasa sudah beredar dalam sir- kulasi darah. Bentuk dan jumlahnya tidak lagi seimbang dalam tubuh hewan kucing tersebut. Gejala klinis antara lain kekurusan, ikterus, anemia, lemah, anoreksia, dyspnoe, sulit menelan, batuk, dan membran mukosa pucat. Selain itu kelenjar pertahanan tubuh juga membengkak, kemudian terjadi hepatomegali, spleenomegali dan pembengkakan pada ginjal. Terbentuk massa tumor pada beberapa tempat. Secara biopsy pada sumsum tulang akan terlihat be- berapa perubahan. Sumsum tulang berwarna merah tua atau abu-abu. Konsistensinya lunak dan terdapat banyak sekali memproduksi sel darah putih. Melalui gambaran darah leukemia ini lebih mudah didiagnosa. Jumlah retikulosit rendah sekali. PCV 8-15%, hemoglobin menurun, sel darah putih (WBC) meningkat, lim- fosit meningkat, Alfaglobulin juga ada peningkatan, dan banyak eosinofil yang belum dewasa beredar dalam darah…dst
