Abstract

ABSTRAK   Sifat fisik tulang merupakan indikator yang baik untuk studi pertumbuhan dan penuaan. Tulang adalah jaringan dinamis karena adanya proses modeling dan remodeling. Tulang berubah tidak hanya pada ukuran dan bentuknya, tetapi juga kepadatannya yang disebabkan  karena perubahan kandungan mineralnya. Osteoporosis atau kekeroposan tulang merupakan salah satu tanda umum penuaaan manusia. Osteoporosis di kalangan anthropoid masih belum diketahui. Dalam penelitian ini kami melakukan pengukuran kepadatan korteks tulang metacarpal simpanse (Pan troglodytes) usia 0 sampai 44 tahun berdasarkan radiografi. Pengukuran dilakukan dengan metode mikro-densitometri pada 68 simpanse betina dan 49 simpanse jantan. Kami menemukan bahwa kepadatan tulang meningkat pesat sampai usia sekitar 10 tahun. Pada simpanse jantan kepadatan tulangnya terus meningkat sampai usia 44 tahun, sedangkan pada simpanse betina kepadatan tulangnya menurun mulai usia 20 tahun. Penurunan kepadatan tulang simpanse betina dapat disebabkan karena kalsium tulang digunakan pada masa kehamilan dan menyusui. Namun demikian, simpanse betina diketahui tidak mengalami menopause. Jadi tidak seperti wanita, kejadian osteoporosis pada simpanse betina bukanlah akibat dari menopause. Kemungkinan hal ini berkaitan dengan berkurangnya kadar estrogen pada simpanse lanjut usia.   Kata Kunci: osteoporosis, kepadatan tulang, metakarpal, simpanse

Abstract

Identification of sequence polymorphism on the D-loop region of mtDNA has been done for various purposes, including health and medical treatment. In this research, single nucleotide polymorphisms were identified in the D-loop region of mtDNA of the Sundanese population in western Java. A total of 118 unrelated and healthy Sundanese probands were collected from closed-traditional kampung adat and open communities distributed in 14 cities and regencies in western Java. DNA amplification and direct sequencing of the D-loop region were proceeded using primers L15990 and H409. Multi-alignment was conducted not only intrapopulation but also with D-loop sequence data stored in GenBank for comparison. In this research, we categorized high-frequency SNPs as less effective for identification in population studies because of their presence in other populations outside Indonesia. Meanwhile, lower-frequency SNPs showed typical variants of Sundanese haplotypes. On the other hand, rare or low-frequency SNPs should be re-examined in larger size of samples to have a better understanding of risk factors for many diseases.

Abstract

Betawi identity was assessed based on the diversity of maternal lines using genetic markers in the D-loop region of mitochondrial DNA. The results of the cleavage by the restriction enzymes DdeI, HaeII, HaeIII, and HinfI showed five patterns of genetic variants which were later named Haplotype I, II, III, IV, and V. Haplotype I had the highest frequency of 75.6%, followed by Haplotype III 11.5%, and Haplotype II 10.3%. Haplotypes IV and V were only found in 1 individual each and were assumed to be individual mutations. The highest haplotype in the Betawi population showed the same restriction enzyme cleavage pattern with all comparison samples from the Sunda and Malay populations. Meanwhile, Haplotype II and III were strongly suspected as the result of the divergence of Haplotype I and can also be found in other ethnic groups in Indonesia. This finding confirms Jakarta as a location for ethnic mixing which then produces a new local culture as Betawi Culture.

Abstract

Studi morfometrik telah dilakukan dengan mengukur 32 karakter dari 176 spesimen Dobsonia dari Papua. Spesimen-spesimen Dobsonia diwakili oleh enam OTU, yaitu G, B, R, E, SP1, dan SP2. Analisis univariat menghitung seluruh spesimen dewasa yang terdiri dari 171 karakter badan dan sayap dan 176 karakter tengkorak dan gigi pada enam OTU tersebut. Selanjutnya digunakan uji-t dan PCA untuk menghitung G, B, dan R, sedangkan tiga OTU lain (E, SP1 dan SP2) tidak dihitung tetapi ikut diproyeksikan ke dalam scatter plot. Hasil uji-t (p<0.05) menunjukkan ada seksual dimorfisme pada D. minor dan D. beauforti. Pemisahan D. magna, D. minor, dan D. beauforti nyata pada karakter badan, sayap, dan gigi berdasarkan PCA. D. emersa terpisah dari spesies lainnya pada karakter badan dan tengkorak. Hasil scatter plot pada SP1 dan SP2 mengelompok dengan D. beauforti pada semua karakter (badan, sayap, tengkorak, dan gigi). Sebanyak 32 karakter yang diukur didapatkan karakter taksonomi yaitu WT, HB, dan TV untuk karakter badan; FA, TIB, dan DIG1P untuk karakter sayap; ONL, POW, PL, dan MH untuk karakter tengkorak; I2M2, M2M2, WM1, dan LM1 untuk karakter gigi. D. minor yang telah ditemukan di Pulau Waigeo tahun 2007 merupakan catatan baru penyebaran spesies ini, sebelumnya hanya tercatat di daratan utama Papua dan Pulau Yapen.

Abstract

Balinese community has evolved since the prehistoric era. The present community is structured into Hinduism caste (Brahmana, Kesatria, Wesia and Sudra), but remnants of their ancient communities, collectively called Bali Aga, have not undergone this structure. The first three castes of modern Balinese that comprises Tri Wangsa gentry were derived from JavanesekingdomofMajapahit(1343 AD). One of Bali Aga communities is Sembiran of Northern Bali. Using chromosomal microsatellite DNA, allelic variability of Sembiran and Tri Wangsa communities was reported. Both of them had the same high frequency of alleles which suggested genetic intermixing or sharing of common ancestor. However, a few alleles were unique for each community. This uniqueness was related to patrilineal system of Balinese community and to high mutation rate of Y chromosomal microsatellite DNA.

Abstract

Face and cranial (craniofacial) shape is highly specific to the individual; therefore, craniofacial shape is often used to identify individuals and to analyze variability in the human population. Previous studies, consisting only of verbal descriptions, suggested that the cranial shape of the Papuan people was highly variable. Despite their usefulness, verbal descriptions cannot fully demonstrate common and local variation in cranial shape. They also cannot be used to extractthe general trend of variation or to group face shapes based on their similarity. Here we attempt to apply geometric analysis, a method of shape analysis, to measure facial anatomical structural landmarks of Papuan people. The craniofacial shape of Papuan people was constructed from those of Arfak people based on 16 anatomic landmarks on the lateral side. Arfak is one of the traditional Papuan tribes in Manokwari, West Papua Province. Our result showed great variation in craniofacial shapes among the Arfak. The nose, chin, and mandible differed significantly, whereas other parts of the face were relatively stable and showed small variations. These differences reflected variations in the facial growth rate. The high level of diversity thus indicates that some parts of the face have higher plasticity in their growth pattern than others.

Abstract

Left-handed individual’s minority has been ubiquitous in human population which leads them to be adaptable in right-handed world. As a preference, daily hand used must be consistentacross individuals and tasks, known as handedness. Handedness needs to be assessed with specific tasks using tools due to consistency of using either hand. There is a different adaptation that leads to creativity in left-handed individuals. The aim of this study is to assess left-handed individuals and measure their creativity. Handedness was examined by self-declared and 10 specific tasks of 493 both primary and secondary school students in Bogor, Indonesia. The total frequency of left-handed individuals was 7.3%. It seems that there are special adaptations that may signal creative behavior for left-handed individuals. The result showed that the left-handed females had higher creativity score than the males on Adjective Check List. Age and sex influence on creativity are discussed.

Abstract

Social networking sites (SNSs) have increased in number and popularity for more than a decade especially for adolescents. Previous studies conducted in western countries have stated that using SNSs could exert positive and negative effects on various aspects of psychosocial development, one of which is empathy. The relationship between SNSs use and empathy has remained unclear, especially in Indonesia. Therefore, the present study aims to determine the relationship between SNSs and empathy on adolescents in Indonesia. This study recruited 1,638 students from junior and senior high school with ages ranging from 12 to 19 years randomly across several provinces in Indonesia. Data collection was carried out by administering online questionnaires to participants consists of informed consent, demographic data, intensity of SNSs use during the past week with the Social Networking Time Use Scale (SONTUS) method, and questions about empathy with the Adolescent Measure of Empathy and Sympathy (AMES) method. Our result showed that higher frequency of using SNSs significantly positive correlated with cognitive empathy, affective empathy, and sympathy among adolescents in Indonesia, which is similar to previous studies, so this may be a general pattern in adolescence. The connections made by SNSs is believed to increase feelings of humanity (sympathy) and also empathy to other humans.

Abstract

Bird communities are the composition of several bird species that live together in the same place, time and interact with other birds. The diversity of birds in an area can be used as an indicator of stabilizing an area. Changes of vegetation structures due to logging practices can affect the availability of resources for bird communities. The objective of the research was to examine diversity, richness, bird species abundance and bird community similarity at HS1 (logged forest 1974), HS2 (logged forest 1989/1990) and HS3 (fully logged forest 1989/1990) in Seblat Nature Recreation Park (SNRP). The research was conducted in July – September 2013. Data collection was conducted by point count method (total 36 points) and mist net method (total 4752 nets hours). The Research showed 85 bird’s species from 33 families were recorded. HS2 was highest value of diversity and richness (H ‘= 3.63, DMG = 10.07). The highest relative abundance species in HS1 was Emerald Dove (Chalcophaps indica), while HS2 and HS3 were Slender-billed Crow (Corvus enca). The bird community similarity was highest in HS2 and HS3 (ISj = 0.58).How to CiteSusanto, E., Mulyani, Y. A., Suryobroto, B. (2016).
