Morphological Characters and Histology of Pheretima darnleiensis
ANDY DARMAWAN,RIKA RAFFIUDIN,TRI HERU WIDARTO
HAYATI Journal of Biosciences , 2012,
Abstract: Pheretima darnleiensis is a native earthworm of Southeast Asia, India, and Japan. Although it is commonly found in Indonesia, the earthworm has never been studied well. This study was aimed to examine the morphological characters and structure of its several organs for an identification purpose, which is important for the earthworm culture. Earthworms were collected in a plot of 55-150 x 55-150 cm width and 20 cm depth at Bogor Agricultural University in Darmaga and Baranangsiang Campuses by hand sorting method. Examinations were carried out on its external as well as internal characters. The histology of the organs was studied using paraffin method. The observed characters on P. darnleiensis were the presence of prostate gland, one pair of male pores on segment XVIII, a cylindrical body with perichaetine setae, caeca on segment XXVII, copulatory pouches without diverticula and stalked glands, bithecal spermatheca with nephridia, and the first spermathecal pore on segment 4/5. In addition, other characters found on P. darnleiensis were the presence of an annular clitellum on segment XIV-XVI, an epilobus prostomium with open base, approximately 40 single pointed setae on segment XIII, one midventral female pore on segment XIV, one pair of lateroventral male pores on segment XVIII, four pairs of lateroventral spermathecal pores on segment 4/5, 5/6, 6/7, 7/8, and the first middorsal dorsal pore on segment 12/13. The histology of P. darnleiensis showed basic structure as found in other earthworms.

Abstract: Pribadi T,Raffiudin R,HarahapIS (2011)Termites community as environmental bioindicators in highlands: a case study in eastern slopes of Mount Slamet, Central Java. Biodiversitas 12: 235-240. Termites ecological behaviour is much affected by land use change and disturbance level. Their variation in diversity can be used as bioindicator of environmental quality. However, termite community response to land use changes and habitat disturbance in highland ecosystems remains poorly understood. This study was conducted to investigate the response of termite community to land use intensification and to explore their role as environmental bioindicator in Mount Slamet. A standard survey protocol was used to collect termites in five land use typesof various disturbance levels,i.e. protected forest, recreation forest, production forest,agroforestry, and urban area. It was found two termite families i.e. Rhinotermitidae and Termitidae with seven species, i.e Schedorhinotermes javanicus, Procapritermes sp, Pericapritermes semarangi, Macrotermes gilvus, Microtermes insperatus, Nasutitermes javanicus, and N. matanganensis. Termite species’ richness and evenness, Shannon-Wiener index, relative abundance, and biomass of termite were declined along with the land use types and disturbance level from protected forest to urban area. Habitat disturbance was the main declining factor of termite diversity. Termite composition changed along with the land use disturbance level. Soil feeding termites were sensitive to the disturbance – they were not found in urban area. Hence, their presence or absence can be used as environmental bioindicator to detect habitat disturbance.
RAPID DETECTION OF THE AFRICANIZED HONEY BEE: A TOOL FOR INDONESIAN ANIMAL QUARANTINE

Abstract: Molecular detection methods were used to determine if Africanized Honey Bees (AHBs) are present in populations of imported Apis mellifera in Indonesia. The cytochrome b ( cyt b gene) was amplified from mitochondrial DNA and digested with the BglII restriction enzyme (cytb/ BglII). Two types of animal DNA extraction kits were used and found suitable for rapid preparation of DNA from A. mellifera by the Animal Quarantine facility. Results showed that all 94 colony samples from beekeepers in Java produced a 485 bp PCR product from the amplification of this gene. Two DNA fragments of 194 and 291 bp from all samples were produced after digestion with BglII. This cytb/ BglII result together with the DNA sequence of cyt b showed that all collected samples of A. mellifera were the non-AHB type. Hence, this study did not detect AHB in Indonesia.

BIOTROPIA : the Southeast Asian Journal of Tropical Biology , 2006,
Abstract: As social insects, termites live in a colony that consist of reproductive (drone and queen), and non-reproductive (soldiers and workers) castes. Workers obtain their food directly from wood, humus, and other substances that contain cellulose. The objective of this study was to examine the alimentary canal of the Neotermes bosei workers. Observations of gut transverse section were carried out through the length, perimeter, and area of each alimentary canal region. The results showed that total length of N. bosei alimentary canal was 13.71+1.28 mm. The canal was divided into fore-, mid-, and hindgut which were 24, 28, and 48%, respectively of the gut total length. Two types of alimentary canal epithelial cells were found, i.e. the squamous and transitional cells. Areas covered with thick muscular tissues were crop, proventriculus, and rectum. Proventriculus was characterized with six large dentitions. There was no gastric caeca in N. bosei midgut, which commonly occurred in chewing insect. Secretory cells .wer e observed at proventriculus and ventriculus regions. Cardiac valve was found at the anterior end of ventriculus. Area with the largest outer perimeter was the rectum pouch. Enteric valve had three internal folds.

Abstract: Yellow rice stem borer ( ) is one of the most important rice pest insectsin Asia, including Indonesia. However, there is a lack of genetic data for this importantagricultural insect. Therefore, this study was conducted to explore intraspecific differentiationof partial 16S mitochondrial gene from Bogor, Karawang, Indramayu and Cirebon(West Java, Indonesia). Here, we reported a total of 325 bp of 16S mitochondrial gene offrom the obtained samples. Among all DNA sequences, three haplotypes of 16Smitochondrial gene were observed and submitted to GenBank under Accession Number ofGU191881, GU191882, GU191883, respectively for haplotype 1, 2, and 3. The haplotype 1was found in all surveyed locations, except Bogor. Haplotype 2 and 3 werefound only in from Cirebon and Bogor samples. These haplotype variations can be applied asDNA markers for early larva detection method among other rice stem borers.Hence, further explorations of the mitochondrial variations of in Java and otherparts of Indonesia are neededmoth, haplotypes, genetic differentiations, molecular identification1* 1 2(1(2Department of Biology, Bogor Agricultural University (IPB), Darmaga,Bogor 16680, INDONESIAIndonesian Centre for Agricultural Biotechnology and Genetic ResourcesResearch and Development (ICABGRD)Scirpophaga incertulasS. incertulasS.incertulasS. incertulasS. incertulasS. incertulasABSTRACTINTRODUCTION

Development and Prospect of Music Therapy in Japan

Voices: A World Forum for Music Therapy , 2005,
Abstract: I have a strange sense that music therapy is something that never fits completely into an existing society, regardless of Western or Asian context. Just aiming at being accepted by society will only drive us to a dead end. Rather, music therapy could conceive the possibility of shaking (aspects of) an existing society and could suggest new (or deeper) values of music in relation to human-beings. For this purpose, we need to cultivate our insights about the culture-specific elements and the universal elements in all areas of clinical, academic, and professional practice. By doing so, we can accomplish "independence" in a true sense, including economic independence some day.
