Abstract

Abstract: Previous studies have found four variant of swamp buffalo in the region of Pampangan based on the characteristics of habitats and morphology namely black buffalo, red,belang, and Lampung. Hence done observation to know the diversity and the kinship relation based on morphological characteristics. A method of on farm was done to data characterization and morphology. Data was analyzed using NTSys ver.2.1 and presented in dendrogram. Cluster analysis done with un-weighted pair-grup method with arithmetic averaging (UPGMA) with a coefficient similarities. The results show that morphology between variant buffalo that in eye color, the color of body, body size, or shapes and sizes horns. Buffalo belang having a dark eyes, the body white ribbed and light. Buffalo black having a black eyes and black body. Buffalo red having a red eyes, the body a red light colored (blonde). Buffalo Lampung allegedly is introduce from Lampung area, adapt and married with a local buffalo. The red buffalo having red eyes, like a black buffalo but shorter size with curved horns the way down. The results of the analysis kinship based on morphological characteristics show buffalo black and buffalo Lampung allegedly came from a single characterized by value a correlation coefficient of 0,85. Inbreeding and adaptation factors believed to cause different the phenotype and morphology. Buffalo  red having scarlet kinship the lowest is as much as 0,57 and predicted to have an ancestor different. Based on these results can be expressed variant swamp buffalo of regional Pampangan tending to low and the difference in the phenotype of influenced inbreeding and adaptation to the environmentKeywords: diversity, kinship, swamp buffalo (Bubalus bubalis), morphological characteristics, Pampangan South SumatraAbstrak : Berdasarkan karakteristik habitat dan pengamatan terhadap morfologi telah ditemukan empat varian kerbau rawa di wilayah Pampangan yaitu kerbau hitam, merah, belang, dan Lampung.  Untuk mengetahui keanekaragaman dan hubungan kekerabatan antar varian kerbau dilakukan penelitian ini. Pengamatam lapangan ditujukan untuk memperoleh data mengenai karakterisasi dan morfologi. Data dianalisis menggunakan NTSYS Ver.2.1 dan disajikan dalam bentuk dendrogram. Analisis kluster menggunakan metode Unweighted pair-grup method with arithmetic averaging (UPGMA) untuk mendapatkan koefisien similaritas. Hasil  menunjukkan perbedaan morfologi antar varian kerbau terlihat pada warna mata, warna tubuh, ukuran tubuh, serta bentuk dan ukuran tanduk.  Kerbau rawa belang memiliki mata gelap, tubuh bergaris putih dan ukuran tubuh kecil; kerbau hitam memiliki mata hitam dan warna kulit hitam;  kerbau mata merah memiliki mata berwarna tubuh lebih terang (warna bulu pirang); sedangkan kerbau Lampung diduga berasal dari daerah Lampung, yang beradaptasi dan kawin dengan kerbau lokal. Kerbau merah memiliki mata berwarna merah, memiliki tanduk yang lebih pendek dan melengkung ke bawah. Hasil analisis terhadap kekerabatan antar varian kerbau rawa diketahui bahwa kerbau hitam dan kerbau Lampung diperkirakan berasal dari satu induk dengan nilai koefisien korelasi sebesar 0,85. Inbreeding dan adaptasi diyakini menjadi faktor munculnya beberapa fenotip dan morfologi. Nilai kekerabatan terendah sebesar 0,57 ditemukan pada varian kerbau merah dan diperkirakan berasal dari nenek moyang berbeda. Berdasarkan hasil tersebut disimpulkan bahwa keragaman genetik dari kerbau rawa yang berasal dari daerah  Pampangan relatif rendah dan perbedaan fenotip lebih dipengaruhi oleh inbreeding dan adaptasi lingkungan.Kata kunci: keragaman, kekerabatan, kerbau rawa (Bubalus bubalis), karakteristik morfologi, Pampangan Sumatera Selatan

Abstract

Odonata is considered an environmental indicator group of freshwater habitats. Thus there is a need to have a good baseline data to use it for monitoring fluvial habitats. However, species composition of Odonata in Kota Waringin Village is poorly known.This study aims to determine the diversity of dragonfly species in the Kota Waringin Village, Puding Besar District – Bangka Island. Data were collected at Three different ecosystems in Kota Waringin Village area (River in Forest, River in oil palm plantations and yard). Location for data collection based on the availability of water resources using purposive sampling method. The species were identified using identification books (Dragonfly of Singapore and Australian Dragonfly). Based on research we revealed 13 species of dragonflies are exist in three sampling locations (Agrionoptera insignis, Brachydiplax chalybea, Heliaeschna crassa, Ictinogomphus decoratus melaenops, Nannophya pygmaea, Neurothemis fluctuans, Neurothemis ramburii, Neurothemis terminata, Orthetrum chrysis, Orthetrum Sabina, Rhodothemis rufa, Zyxomma petiolatum and Rhyothemis phyllis). Keywords       :  Odonata, Dragonflies, Inventory, Conservation, Bangka Island

Abstract

The research " The Effect of Applicated Ash Sawdust on Swamp Land (Indralaya) For Vegetative Growth of Red Pepper (Capsicum annum L.) var. Cemeti ’’ has done, from  September to November 2017. It was conducted at green house and Pest Diseases Plant Laboratory, Plant Protection Department, Agriculture Faculty, University of Sriwijaya. This research was aimed to know the effect of applicated ash sawdust on vegetative growth of red pepper. The Completely Randomized Design with treatments are : 10, 20, and 30 g/ kg marshland and without ash sawdust (control), with 6 replicates each treatments. The result showed that applicated ash sawdust on measure 10 g/ kg soil significantly on number of growth 53.28 cm and number of branch 9.2, but not differ on dry weight of red pepper.Keywords :  Swamp land, ash sawdust, branch, red pepper
