Abstract

Diadematidae is one of sea urchin families belongs to Class Echinoidea that can be found in intertidal zone untill deep sea. These sea urchins have long spines, and some of them are toxic spines. However, they have important ecological roles. This research aimed to identify the species richness of sea urchins that belong to Family Diadematidae in Pantai Selatan Gunung Kidul as well as describe their taxonomic characters. Specimens were collected from five beaches, namely Krakal, Kukup, Drini, Sepanjang, and Wediombo. Collected specimens were relaxated by using MgCl272% in sea water and the fixed by using 10% formalin in sea water. Finally, they were preserved in 70% Ethanol. Some morphological characters were observed carefully, namely shape and colour of spines, shape of test, shape of genital plate, the existance of orange ring, white spot and iridipore of apical system, interambulacral region, and number of pores. The results showed that there were five species of Diadematid sea urchis in Pantai Selatan Yogyakarta; they belong to two genus, namely genus Diadema dan genus Echinotrix. Genus Echinotrix and Diadema can be fount in Kukup, Wediombo, and Sepanjang, but can not be found in two others beach.

Abstract

Iridovirus was known as agents that caused serious systemic disease in freshwater and marine fishes. The mortality up to 100% of orange-spotted grouper (Epinephelus coioides) due to iridovirus infection has been reported in Indonesia. The gene encoding capsid protein of iridovirus is supposed to be conserved and has the potency for the development of control methods. The objectives of this study are to clone the gene encoding capsid protein iridovirus and to analyze their sequences. The   spleen tissues of orange-spotted grouper were collected and extracted their DNA. The DNA fragment of capsid protein of iridovirus genes were amplified by PCR using designed primers with the extraction DNA as templates. The amplified DNA fragments were cloned in pBSKSII and sequenced.  The genes encoding capsid protein of iridovirus from Jepara and Bali were successfully amplified and cloned. The Jepara clone (IJP03) contained complete open reading frame (ORF) of the gene composed by 1362 bp nucleotides which encoded 453 amino acids. Those Jepara and Bali (IGD01) clones shared 99.8% similarity in nucleotide level and 99.4% at amino acid level. Based on those sequences, Indonesian iridovirus was belonged to genus Megalocystivirus and shared 99,6-99,9% similarity on nucleotide level with DGIV, ISKNV, MCIV, and ALIV

Abstract

The availability of specific and rapid detection methods is essential for monitoring the health status of farmed species, particularly in viral disease as in this case early diagnosis is a critical factor in containing disease outbreaks. Jembrana Disease Virus (JDV) is a lentivirus that causes an acute, severe disease syndrome in infected Bali cattle in Indonesia, resulting in heavy economic losses because of the high mortalities. The virus-host interaction and the modes of transmission are still unknown. The goal of the research was to designa probe candidate of Jembrana Disease Virus based on envelope-transmembrane (env-tm) gene to optimize Jembrana disease detection method. The DNA fragment derived from env-tm of JDV was used, cloned in pGEX-TM and expressed in E.coli DH 5α. Sequence analysis was conducted with BLAST programs from NCBI. Sequence analyses of the fragments of env-tm clone, indicated that it has a very closed genetic relation with 97,68% homology identity. Probe was designed based on the conserved region of env-tm using Geneious resulted in JT2 252 bp long. BLAST analyses showed that probes had high specifity to other strains of JDV in Indonesia.Key words : probe, env-tm, JDV, specifity, sensitivity.

Abstract

ABSTRAK Albinisme merupakan kelainan genetik autosomal resesif  berupa gangguan sintesis melanin yang terjadi pada manusia. Albinisme dibagi menjadi dua kelompok besar, yaitu Ocular Albinism (OA) dan Oculocutaneous Albinism (OCA). Berdasarkan gen yang mengalami mutasi, OCA dibedakan menjadi 4 tipe yaitu OCA1, OCA2, OCA3 dan OCA4. OCA4 disebabkan mutasi pada gen MATP. Penelitian yang telah dilakukan dengan PCR-SSCP (Polymerase Chain Reaction-Single Stranded Conformation Polymorphism) mendeteksi adanya mutasi pada ekson 5 gen MATP, pada penderita albinisme di Wonosobo, Jawa Tengah. Sekuensing ekson 5 gen MATP dilakukan untuk mengidentifikasi tipe mutasinya. DNA diisolasi dari sampel darah penderita dan digunakan sebagai template untuk amplifikasi ekson 5 gen MATP dengan metode PCR. Produk PCR selanjutnya digunakan sebagai template untuk sekuensing dengan metode Sanger. Hasil sekuensing dianalisis menggunakan program Clustal-W dan dibandingkan dengan sekuens ekson 5 gen MATP dari International DNA Data Base (nomer akses AF172849.1). Hasil analisis menunjukkan adanya pada perubahan basa nukleotida no.1122 dari C menjadi G (c.1122 C>G) yang mengakibatkan mutasi missense, yaitu fenilalanin menjadi leusin, pada asam amino nomer 374 (p.374 Phe/Leu).   Kata kunci : OCA4, mutasi, ekson 5, gen MATP

Abstract

Pseudodiaptomus species are one of the copepods species as a superior live feed to date due to their nutrition and digestive enzyme contents. Some of them have been used as natural for rearing marine fish larvae. The purposes of this study were to compare the nutritional and protease activity between two species of Pseudodiaptomus originated from Indonesian waters, and to determine more superior species to cultivate. Two different feeds i.e. Thalassiosira sp. and milk powder were used to grow the Pseudodiaptomus species. Analysis of amino acids (AAs) and fatty acids (FAs) profiles were carried out for both the Pseudodiaptomus species samples and the feeds, while the protease activity assay was carried out only for the Pseudodiaptomus species samples. Results indicated that the nutritional and protease activity profiles of Pseudodiaptomus were affected by the types of feed. Pseudodiaptomus code P61 was more superior to Pseudodiaptomus code P71. This code P61 species contained a wide variety of essential fatty acids and exhibited stabile protease activity under the different feeding treatments. However, P61 contained a lower total AA content than P71. Both of them could be cultivated because they were complementary in nutrients to each other.

Abstract

The Community Service Activities for the Independent Campus Learning Program (PkM MBKM), which involves lecturers and students has been done. The program aims to empower the people of Padukuhan Malangrejo, Wedomartani, Ngemplak Sleman, regarding the use of natural dyes for healthy food products. The targets during this program were 14 Women Farmers Group (KWT) participants, 10 elementary school students and 10 teenagers. In this course, we did the socialization of the activities, increasing the community literacy about natural food coloring and its benefits for health, by using the learning modules for children, adolescents and members of Women Farmer Groups (KWT). The training was carried out on the production of natural dyes that can be stored, as well as the creation of colorful food and drink recipes. Evaluation of literacy activities is assessed from understanding the material at the beginning (pre-test) and end (post-test) of the activity. Food products with natural dyes were organoleptically tested in communities outside Malangrejo. Other activities include assistance in the production of BiTel pudding (beetroot and butterfly pea coloring) with limited marketing, obtaining a Hygiene and Sanitation Certificate (SLHS) from the Health Service, Sleman. Activities to plant natural food dyes are carried out in yards and less productive land. Planting methods were adjusted to the type of plant, both horizontally and vertically. The results of the activity showed an increase in community participation and understanding of the benefits of natural food coloring (16.4%), increased literacy in the youth group (4%), KWT participants (2.9%), while for elementary school students there were 40% of participants who got a score of 100 %. This activity also gave rise to Micro, Small and Medium Enterprises (MSMEs or UMKM) which produce food with natural dyes, as well as the enthusiasm of KWT Malangrejo members in using their home gardens to produce natural food dyes. The MBKM PkM program for village development, which was implemented in Padukuhan Malangrejo, was well appreciated by the community and the Wedomartani Village leader, and hopefully the programs will continue in the following year.
