Abstract

Pada saat ini undur-undur banyak dicari oleh manusia karena mengandung zat anti diabetes. Jika tidak ada semut yang terjebak di lubang undur-undur, maka undurundur tidak akan memperoleh makanan yang dikhawatirkan menurunkan kesintasan undur-undur. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh berbagai jenis umpan semut terhadap kesintasan undur-undur. Jenis bahan makanan yang dapat mengundang semut yang digunakan pada penelitian ini yaitu berupa air gula, sirup dan kulit udang. Kesintasan hidup undur-undur diamati selama 3 bulan. Data kesintasan hidup undur-undur dianalisis dengan menggunakan Anava Dua jalur serta berat dan panjang undur-undur dianalisis dengan t-test. Hasil penelitian menunjukkan bahwa kesintasan undur-undur terjadi pada semua perlakuan yakni pada umpan semut yang berupa air gula, sirup dan kulit udang, hal ini ditunjukkan dengan jumlah undur-undur yang hidup hingga akhir penelitian sebanyak 93-97%, pada kelompok tanpa perlakuan (alami) kesintasannya hanya 80%. Umpan semut kulit udang mendatangkan 2 jenis semut sedangkan umpan semut air gula dan sirup hanya mendatangkan masing-masing satu jenis semut. Semut tersebut menjadi makanan undur-undur dan meningkatkan kesintasan dan pertumbuhan undur-undur. Dari hasil penelitian dan pembahasan dapat disimpulkan bahwa pemberian umpan semut sebagai makanan undur-undur dapat meningkatkan kesintasan undur-undur.Gratus much sought after by humans at this time because it contains anti-diabetic agent. If there are no ants are trapped in the hole gratus, then gratus will not get food that may reduce survivorship gratus. The aim of this research is to to determine the effect of various types of ant bait to survivorship gratus. Types of food that can invite ants used in this research is in the form of sugar water, syrup and shrimp shells. Survivorship life gratus observed for 3 months. Data survivorship life gratus analyzed using ANAVA Two long lines and, heavy and gratus analyzed by t-test. The results showed that the survival rate gratus occurred in all treatment that is on the ant bait in the form of sugar water, syrup and shrimp shells. This is indicated by the number gratus living up to the end of the study as much as 93-97%, in the group without treatment (natural) survival rates of only 80%. Ant bait shrimp shells bring two types of ants ant bait water while sugar and syrup only bring one of each type of ant. The ants feed gratus and enhances survival and growth gratus. From the results of research and discussion can be concluded that feeding ants as food gratus can increase survivorship gratus.

Abstract

Northern coastal areas of Central Java potentially produces sharks and rays (Chondrichthyes) for dishes. However, lack of community understanding of protected species catchment affects the Chondrichthyans conservation management. This study aimed to identify of total Chondrichthyans that were captured by fisherman correlated to the conservation knowledge and action in northern coastal areas of Central Java. This research was conducted by using interview, and direct observation. Samples were collected in fish capture household places in Tegal, Pemalang, Pekalongan, Semarang, Pati, and identified in Animal Taxonomy Laboratory of Biology Department, Universitas Negeri Semarang. Data were analyzed using descriptive qualitative based on the morphology characteristic. This research found that every season, at least 1,106 individuals from 23 species of Rajiformis and Lamniformis (Chondrichthyes) orders was captured. This condition was aggravated with lack of access to information and low fisherman’ awareness of protected species. It was also found that shark and ray trading generates value chain in culinary business. It increases fish consumption demand that only can be provided by fish catchment from the ocean. The implication of species catchment is declining population of Chondrichthyes in Central Java north areas. Based on the research, a high demand and lack of access to information correlated with declining community awareness on conservation actions. this research adds more information as an effort to conserve shark and ray species based on problems faced by fishermen. The information is also able to be applied as a foundation to develop community based conservation action.
