Abstract

Katak Fejervarya cancrivora merupakan kelompok dari kelas amfibi yang habitatnya sangat dipengaruhi oleh perubahan kondisi habitat dan aktivitas manusia. Salah satu upaya untuk mempertahankan keanekaragaman hayati yaitu memanfaatkan teknologi reproduksi buatan dengan melakukan induksi pematangan gonad menggunakan hormon hipofisa dan ovaprim. Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian hormon hipofisa dan ovaprim terhadap pematangan gonad dan keberhasilan fertilisasi pada katak Fejervarya cancrivora, serta mengetahui pengaruh perbedaan pemberian pakan pada pertumbuhan berudu katak Fejervarya cancrivora. Injeksi dilakukan pada katak betina yang  hampir matang gonad dengan total dosis injeksi 250 µl secara intraperitonial. Setelah dipijahkan dan difertilisasi, telur dipelihara sampai menetas dan diberikan dua perlakuan pakan, yaitu pakan bayam  rebus (P1) serta  pakan bayam rebus dan kuning telur rebus (P2). Hasil penelitian menunjukkan pada perlakuan injeksi hipofisa dihasilkan telur 632 butir sel telur dan berhasil menetas 65,67%  dan perlakuan injeksi ovaprim sebanyak 108 butir sel telur dan dapat menetas 75,92%. Hasil  perlakuan P1 dan P2 pada kedua jenis injeksi tidak terdapat perbedaan panjang (p>0,05) namun terdapat perbedaan berat (p<0,05) pada perlakuan selama masa metamorfosis. Persentase jumlah berudu yang berhasil bermetamorfosis sempurna pada perlakuan injeksi hipofisa sebanyak 41,12%, sedangkan pada perlakuan injeksi ovaprim sebanyak 31,67%.

Abstract

Javan Munia is one of the common species of birds that found in west area of Indonesia (Sunda land). This species is endemic to Indonesia (Lombok, Bali, Java, and South Sumatra). The large population, especially during the harvest season makes this bird became a major pest for agriculture. This research aims to determine the adaptive behaviors of Javan Munia that become major reasons of widely spreads and the influence of these factors to the distribution. Observations made in Kalibaru, Banyuwangi, East Java, which is a mostly agricultural area. Any form of behavior in the territorial area (nesting and courtship areas) and range area (where colonize and feed) were observed periodically in the past 12 months. Sunbathing is known as a activity that undertaken by many species of birds, including the Javan Munia. This munia has specific mating and nest construction behaviour. The development of Javan Munia is very quickly, in 40 days, child will become a new adult. Javan Munia is very easy to adapt to the surrounding environment, including the used of oil palm (Elais guineensis) fiber and paper receipts as nest material. There are a possibility of invasive occurrence to the entire island of Sumatra by this species. It is quite possible because of the opening of oil palm plantations and settlements continue, until Aceh. The spread possibilty to east end of distribution (Lombok) can occur up to Nusa Tenggara Island, because of short distances between the islands and similiar vegetation circumstances.

Abstract

ABSTRAK This study was carried out faculty Mathematics UB Malang 1 June 2012. This study aims to determine the effect of variations of food to African catfish (Clarias Gariepinus) using pests (Gold snails) and poultry waste (feces gemak) on the growth of channel catfish as well as to reduce the cost of purchasing an expensive artificial feed, so need to note the retention and protein efficiency ratio of fish needs every day. The variables were observed in this study was the weight, length, body color. The study was conducted using completely randomized design (CRD) with three treatment that feeding by comparing the artificial fish feed plant, fish feed made ​​with gold snails and artificial feed with poultry manure with each ratio 100:0, 70:30, 70:30 @ weight of each fish and each made ​​repeated 4 times, with other factors such as pH equated, light intensity, water temperature, water quality, oxygen levels. The results showed that there was no significant difference between the treatment given to the growth of the weight and length of the fish, but mixed with dung feeding quail in the ratio of 70: 30 more profitable because the costs were less. Feeding pellets mixed with the ratio of 70:30 keongmas also beneficial although slightly larger than quail dirt. Although the number of calories produced is less than the controls, but not significantly different, and the provision of a varied diet had no effect on the shape and color of the fish where the fish are shown color remains black and shiny, which means normal. So dirt and keongmas quail can be a safe alternative to feed and to reduce maintenance costs.   Keywords: Lele Dumbo, food, growth, color

Abstract

Ectoparasites were common found on fishes. Ectoparasites often infect parts of the fins, scales, operculum and gills in fish. This research aims to determine the types of ectoparasites on fish family Cyprinidae and the influence of environmental conditions on the number of ectoparasites. This research was conducted in three pools restaurant in Malang Raya region, then measured abiotic factors of pool water. Fish as the host of ectoparasites, taken using nets and anesthetized by using 3 phenol chloroform. Fish scales and fins were observed. Ectoparasites that attach to the parts taken and put in 70% alcohol. Ectoparasites observed and identified under a microscope. Measurement data of water quality and quantity ectoparasites were analyzed using SPSS 16 program. Argulus japonicus is a species of ectoparasite was founds in B Batu restaurant and I Dau restaurant. While ectoparasites found in G Malang restaurant was Lernaea cyprinacea. Argulus japonicus and Lernaea cyprinacea were exotic species from Japan. The entry of ectoparasites caused by introduction of Koi fish to Indonesia. The results showed that there were significant differences in the number of ectoparasites I Dau with B Batu and G Malang restaurants respectively. The correlation result between the number of ectoparasites and the physico-chemical factors were showed that the pool water DO levels were positively correlated to the number of ectoparasites.   Key word: Ectoparasites, fish family Cyprinidae, restaurant pond at Malang Area, SPSS 16

Abstract

The restoration effort in Tamban Beach may reflect the role services of mangroves as suitable habitats for those surrounding diversity, especially on avifauna. Here we assess the diversity and community of avifaunal throughout types of mangrove ecosystems. We surveyed the avifaunal within four stations (i.e., natural mangrove area, restored mangrove area since 2009 and 2014, and degraded mangrove area) in Tamban Beach, Sumbermanjing Wetan, East Java during March 2021 using Audiovisual Encounter Survey (AES) methods. We present the statistic descriptive analysis of α-diversity index (taxa diversity, dominance index, Simpson’s index, Evenness, Shannon-Wiener diversity index, Brillouin index, and Margalef species richness) as diversity assessment also conservation status of each species. The Principal Component Analysis (PCA) was performed to investigate the community variation within each site. We found 38 species from 22 families and 11 orders of avifaunal across the sites. The diversity of avifauna was high in a degraded area due to the mixture of habitats, although the natural and restored area yields some specialists. The type of mangroves might not be the sole factor affecting the avifauna diversity correlation, highlighting the importance of conservation strategies in the area.

Abstract

This study aims to determine community structure and composition of liquid organic fertilizer (POC) against visiting insects in block Refuge and to determine the public perception of the block Refuge and insect’s conservation. Analysis of insects data are obtained from the important of index value, diversity (index’s Shannon Wienner). Insect abundance spring that treatment total 298 individuals and control 168 individuals. Insect abundance spring that treatment total 262 individuals and control 116 individuals. Insect diversity during flowering season given treatment was 2,11 andcontrol 1,49. Diversity during fruiting season was similar, given treatment it was 1,87 and control 1,42. Abundance of insect on both seasons with treatments and control had a significance of P=0,004. Similarities between insects on flowering season treatments between fruiting season treatments between organic fertilizers of different seasons 0,94 and control 0,80. Analysis on abiotic factors correlated with insect abundance with R-square value of 15%. Local perception towards refugia blocks was found to be low (46%) and medium (48%). Local perception towards convservation was found to be low (34%) and medium (63%). Local perception is affected by knowledge and non responsive actions towards insect conservation.Key words: Insect, Liquid Organic Fertilizer, Refugia
