Abstract

In accordance with the paradigm of 21st century education, teachers are required to facilitate students with the learning process which addresses the improvement of students’ higher thinking skill. The community service which was conducted in  MTs Al Ikhlas Soe, East Nusa Tenggara was aimed at: 1) culturing as well as developing students’ literacy in school; 2) improving students’ capacity in literacy; 3) managing students’ knowledge and higher thinking skill, as considerable as 4) elevating teachers’ professionalism so that learning process can be more effective and efficient. The methods used were lecture, discussion, brainstorming, simulation, and assignment. The materials delivered were about the arrangement and development of literacy-oriented teaching materials. The product produced from the training was implemented in learning process on VII graders. This was aimed to observe whether there was an improvement gained after the training given. The participants of this community service were 13 teachers and 34 students of MTs Al Ikhlas Soe. The results showed that teachers’ skill in arranging teaching materials has been improved. Furthermore, students’ understanding about the concept or their knowledge related to the materials has been upgraded after experiencing the implementation of literacy-oriented learning.

Abstract

Indonesia merupakan negara dengan tingkat eksploitasi biawak V. salvator terbesar di dunia yang sebagian besar untuk melayani permintaan perdagangan kulit. Tingginya permintaan kulit biawak di Indonesia mengkhawatirkan menyebabkan turunnya populasi satwa tersebut. Penelitian ini bertujuan untuk mempelajari anatomi organ reproduksi jantan biawak air asia (Varanus salvator) (Reptil: Varanidae). Dua ekor biawak jantan dewasa digunakan dalam penelitian ini. Hewan dianestesi, dilakukan exanguinasi, dan difiksasi dengan larutan paraformaldehida 4% secara perfusi. Pengamatan dilakukan terhadap situs viscerum, morfologi, dan morfometri organ reproduksi mulai testis sampai hemipenis. Secara makroskopis, organ reproduksi jantan V. salvator terdiri atas testis, ductus epididymidis, ductus deferens dan hemipenis yang masing-masing berjumlah sepasang. Posisi testis menggantung di dinding dorsal coelom melalui mesorchium. Dari bagian dorsal testis terdapat ductus epididymidis yang panjangsampai di ujung kaudal ginjal. Ductus deferens, berupa saluran kecil, lurus dan berakhir di ujung hemipenis yang terletak di dalam pangkal ekor. Pada bagian kranial hemipenis ditutupi oleh papillae berbentuk konikal. Di kaudal dari hemipenis ditemukan otot retraktor yang memanjang ke arah ekor, dan diduga berperan menarik hemipenis ke dalam setelah kopulasi. Organ reproduksi jantan biawak secara umum mirip dengan reptilia lain khususnya ular dan kadal, dengan karakteristik adanya sepasang hemipenis.Kata kunci: Varanidae, Varanus salvator, organ reproduksi jantan, hemipenis, otot retraktor. (Anatomy of The Male Reproductive Organ of Water Monitor, Varanus salvator (Reptil: Varanidae))Indonesia is a country with high levels of exploitation of Varanus salvator that mainly serve the demand of leather trade. The high demand of lizard leather in Indonesian was alarming, cause a decline population of these animals. To improve our understanding on reproduction organs of the animal, we conduct this anatomical study. The study was used two adult male lizards. The animals were anesthetized, exanguinated and fixated in 4% paraformaldehyde by tissue perfusion method. Observations were performed to the visceral site, morphological and morphometrical of the male reproductive organs, from testes to hemipenes. Macroscopically, male reproductive organs of V. salvator were a pair of testes, epididymidis ducts, deferens ducts and hemipenes. The testis attached to dorsal wall of the coelom and fixed by the mesorchium. The epididymidis duct was long tubes that located in the dorsal of testes, winding up at the caudal end of the kidney. The deferens duct was a small duct, running straight and last at the end of each hemipenis, located at the base of the tail. The cranial part of each hemipenis was covered by conical shaped papillae. Furthermore, at the caudal of each hemipenis was found the retractor muscle that extends toward the tail, and is thought to contribute to the retracting hemipenis after copulation. The male reproductive organs of V. salvator are generally similar to the other reptiles, especially snakes and lizards, with peculiar a pair of hemipenes.Keywords: Varanidae, Varanus salvator, male reproductive organs, hemipenes, retractor muscles.

Abstract

Varanus salvator bivittatus has a pair of hemipenes, which is macroscopic anatomically like the copulatory organ in other amniotes, cylindrical-shaped (truncus) with quite flexible, and it located on the base of the caudal tailof the cloaca. However, information about the microscopic anatomy of hemipenes of this animal is scientifically unpublicized. Therefore, the aim of this research is to study the microscopic anatomy of hemipenes of male Varanussalvator bivittatus. The animals were sacrificed by exsanguination under deep anesthetized and fixed in 4 % paraformaldehyde through perfusion then observed visceral site and morphometric. Histomorphological evaluationwas obtained by paraffin preparation with section thickness of 3-4 μm then stained in Hematoxylin-Eosin (HE) and Masson’s Trichrome (MT). The results showed that truncus of hemipenes was lined by stratified squamousepithelium and supported with thick of dense connective tissue and contain cavernous body and blood vessels are found, the muscles not found. The presence of connective tissue that supported in the down part sometimesmake hemipenes are rigid while prurient condition. In the caudal of truncus hemipenes there is retractor muscle of hemipenes which arranged by striated muscles. Hemipenes is flexible because contain with much of blood vesselthat found in truncus hemipenes.

Abstract

The study was aimed to describe the macromorphological and micromorphological aspect of the accessories gland of Male Varanus salvator bivittatus. Two adult male lizards with 45.60 cm SVL were used in this experiment. The animals were sacrificed by exsanguination under deep anesthetized and fixed in 4 % paraformaldehyde through perfusion and then its visceral site was observed. Histomorphological evaluation was obtained by paraffin preparation with section thickness of 3-4 μm then stained in Hematoxylin-Eosin (HE), Alcian Blue (AB) pH 2.5 and Periodic Acid Schiff (PAS). The result showed that accessories gland which was found at the dorsal of cloaca, specifically at the caudal end of deferent duct that was a hemipenile bulge. Microscopically, the accessories gland was identified as tubular mucous type gland which was resemble to bulbourethral gland in mammals. The cytoplasm of the secretory cells showed weak reaction, while strong reaction was observed in the luminal mucus which was stained by AB staining. In contrast, luminal mucus showed a weak reaction to PAS staining. In conclusion, V. salvator bivittatus has only one accessory gland and its microanatomical structure resembled the bulbourethral glands.

Abstract

The study aims to determine the histological structure of the testes, ductus epididymidis and ductus deferens of Varanus salvator bivittatus. The tissue samples were obtained by the histological techniques preparation with thickness section is 3-4 µm then stained using hematoxylin-eosin (HE) and Masson's Trichrome (MT). The result showed that testes are covered by tunica vaginalis and tunica albuginea (tunica fibrous and tunica vasculosa). Tubulus seminiferous as a parenchyma are found in lobules of testes which are formed by septum as extension of tunica albuginea. Tubulus seminiferous is composed by layers of germinal epithelium cells consist of spermatogenia, Sertoli cell, spermatocyte and spermatid which is developed further to be spermatozoa in the lumen of tubulus. Among the tubulus seminiferous, there are groups of epithelioid cells called Leydig cells. The end of tubulus seminiferous formed ductus epididymidis which then ended up and known as ductus deferens. Epididymis is covered by dense connective tissue. Ductus epididymidis is divided into three segments: cranial, medial and caudal. It is lined by pseudostratified columnar epithelium which is varied in its thickness, amount and diameter of lumen. Lumen of the ductus deferens was lined by pseudostratified ciliated columnar epithelium and thin muscularis mucosal layer and thick circular smooth muscle were covered externally.Key words: Varanus salvator bivittatus, testes, ductus epididymidis, ductus deferens, micromorphology
