Abstrak: Faktor alam dan lingkungan dapat mempengaruhi pola keberadaan semut. Penelitian ini bertujuan untuk mempelajari pola keberadaan semut tanah di area permukiman tepian Sungai Musi Kecamatan Gandus Palembang. Metode penelitian ini adalah deskriftif.Stasiun penelitian meliputi rumah, tepi sungai, semak, butan dan kebun. Pengambilan contoh sampel semut menggunakan metode hand collecting dan perangkap umpan (baited trap).Hasil penelitian semut tanah Solenopsis germinata dan Paratrechina longicornis hampir ditemukan disemua stasiun.Spesies semut yang paling sedikit ditemukan, yaitu Diacamma intricatum danPheidole megacephala. Rumah kurang dari 100 m dari tepi sungai Musi ditemukan tiga spesies semut, yaitu dua dari subsuku Myrmicinae dan satu dari Formicinae (S. germinata, P. megacephala dan P. longicornis). Ketiga spesies ini sama dengan yang ditemakan pada semak-semak.  Lokasi yang berjarak 100-200 m dari tepi sungai memiliki komposisi dan keanekaragaman semut yang semakin meningkat. Stasiun rumah ditemukan sebanyak tiga spesies, yaitu S. germinata, Pheidole sp, dan P. longicornis. Stasiun semakditemukantiga jenis semut, yaitu S. Germinate, Monomorium pharaonisdan T. melanocephalum. Stasiun kebun ditemukan empat spesies, yaitu: Acanthomyrmex sp., S. germinata, P. longicornis, danCamponotus ligniperda.Stasiun hutan ditemukan enam spesies yaitu: Acanthomyrmex sp., S. germinata, P.longicornis, Camponotus ligniperda danDiacamma intricatum. Jumlah jenis semut yang paling banyak ditemukan adalah di stasiun hutan. Pola keberadaan semut di berbagai lokasi tepian sungai Musi Gandus Palembang memiliki pola fluktuasi jumlah dan jenisnya.Kata kunci: semut tanah, pola keberadaan, sungai Musi danPalembangAbstract: The natural and environmental factors can affect the pattern of ants. This study aims to study the pattern of the presence of soil ants in the settlement area of the banks of the Musi River, Gandus, Palembang. This research method is descriptive. The research station includes houses, river banks, bushes, butane and gardens. The sampling ant samples using the method of hand collecting and baited traps. The results of research on the ground ants Solenopsis germinata and Paratrechina longicornis are found in almost all of stations. The fewest ant species found were Diacamma intricatum and Pheidole megacephala. The houses less than 100 m from the banks of the Musi river are found by three ant species, namely two from the Myrmicinae sub-tribe and one from Formicinae (S. germinata, P. megacephala and P. longicornis). These three species are the same as those found in bushes. The location which is 100-200 m from the river bank has an ant composition and diversity that is increasing. The housestations were found as many as three species, namely S. germinata, Pheidole sp, and P. longicornis. The bush station found three types of ants, namely S. Germinate, Monomorium pharaonis and T. melanocephalum. The garden station found four species, namely: Acanthomyrmex sp., S. germinata, P. longicornis, and Camponotus ligniperda. The forest station found six species, namely: Acanthomyrmex sp., S. germinata, P.longicornis, Camponotus ligniperda and Diacamma intricatum. The number of ant species most commonly found is at the forest station.

ABSTRACT Factors affecting fecal microorganism survival and distribution in the Antarctic marine environment include solar radiation, water salinity, temperature, sea ice conditions, and fecal input by humans and local wildlife populations. This study assessed the influence of these factors on the distribution of presumptive fecal coliforms around Rothera Point, Adelaide Island, Antarctic Peninsula during the austral summer and winter of February 1999 to September 1999. Each factor had a different degree of influence depending on the time of year. In summer (February), although the station population was high, presumptive fecal coliform concentrations were low, probably due to the biologically damaging effects of solar radiation. However, summer algal blooms reduced penetration of solar radiation into the water column. By early winter (April), fecal coliform concentrations were high, due to increased fecal input by migrant wildlife, while solar radiation doses were low. By late winter (September), fecal coliform concentrations were high near the station sewage outfall, as sea ice formation limited solar radiation penetration into the sea and prevented wind-driven water circulation near the outfall. During this study, environmental factors masked the effect of station population numbers on sewage plume size. If sewage production increases throughout the Antarctic, environmental factors may become less significant and effective sewage waste management will become increasingly important. These findings highlight the need for year-round monitoring of fecal coliform distribution in Antarctic waters near research stations to produce realistic evaluations of sewage pollution persistence and dispersal.

One of the interesting cultural potentials to be studied is traditional houses. This traditional house has its own uniqueness in every area. One of the uniqueness can be seen from the many ornaments in it. Diversity has its own meaning and function. Ornaments is one of the historical heritage of Indonesia where almost all the tribes in Indonesia can be found various kinds of ornaments that reflect the techniques of each region in Indonesia. Ornament Batak Toba is one of the many ornaments that exist in this country Indonesia. Toba Batak ornament can be found in North Sumatera Province precisely in Samosir regency which always apply Toba Batak ornament as decoration or as identity in important building for Batak Toba, for example in traditional house building in Huta Siallagan, Tomok Village and Huta Bolon.This research is classified in research using descriptive-comparative research method, doing the study by comparing the existing ornaments in these three villages with theories about Ornaments Gorga Rumah Adat Batak Toba, then do the analysis of the condition in accordance with the theory used as a reference

Rumput laut atau seaweed termasuk tumbuhan berthallus yang banyak dijumpai hampir di seluruh pantai Indonesia, terutama wilayah pantai yang mempunyai rataan terumbu karang.  Perbedaan mendasar sistem hidupnya dengan tumbuhan darat adalah dalam pengambilan zat-zat makanan. Tumbuhan darat sangat bergantung pada akar sebagai alat pengambil/ penyerap zat hara dari substrat, sedangkan rumput laut menyerap zat hara yang dibutuhkan bagi pertumbuhannya dari medium air dengan cara difusi melalui permukaan substansi fisiknya.Penelitian ini bertujuan untuk mengetahui struktur komunitas rumput laut di perairan Pasir Panjang Pulau Limbah, Kecamatan Paguyaman Pantai, Kabupaten Boalemo, Provinsi Gorontalo. Metoda penelitian yang digunakan adalah bersifat diskriptif.Adapun pengumpulan data dilakukan dengan metode sample survey methods. Hasil penelitian menunjukan bahwa perairan Pulau Limbah di dominasi oleh Rumput Laut Coklat dengan kelimpahan tertinggi Padina australis. Nilai Indeks Keanekaragaman (H’) Rumput Laut tertinggi terdapat pada stasiun C dengan nilai rerata: 1,854 dan yang terendah pada Stasiun A dengan nilai rerata: 1,469. Nilai Indeks Keseragaman (E)  nilai tertinggi terdapat pada Stasiun C dengan nilai rerata: 0,679 dan terendah pada stasiun A dengan nilai rerata: 0,668. Nilai indeks Dominansi (C) tertinggi terdapat pada Stasiun A dengan nilai rerata : 0,251 dan nilai terendah stasiun B dengan nilai rerata: 0,187. Analisis Ragam (Anova) menunjukan bahwa stasiun penelitian memberikan perbedaan yang nyata (P≤0,05) terhadap nilai Indeks Keanekaragaman (H’), Indeks Keseragaman (E) serta Indeks Dominasi (C).  Seaweed including thallus plants that are found almost all over the coast of Indonesia, especially on beaches that have coral reefs. Seaweed is a photosynthetic organism as well as plants on land. The fundamental difference of his life system is in the taking of food substances. Ground plants realy heavily on roots as a nutrient removal device from the substrate, while seaweed absorbs the nutrients needed for its growth from the water medium by diffusion through the surface of its physical substance. This study aims to determine the structure of seaweed communities in Limbah Island Waters, District Paguyaman Beach. The results showed that the waters of Limbah Island is dominated by brown seaweed with the highest species abundance was Padina australis. The highest index value of Seaweed diversity (H’) was found at station C with average: 1,854 and the lowest at station A with a mean of: 1,469. For uniformity index value (E) the highest value is at station C with average: 0,679 and the lowest at station A with a mean of: 0,668. The highest index value of dominance (C) is at station A with a mean of: 0,251 and the lowest value at station B with a mean of: 0,187. The result of the analysis of variance (Anova) showed that the research station give a significant difference (P≤0,05) to the Diversity Index (H’), Uniformity Index (E) and Domination Index (C).

Somatotype of the human body is influenced by many factors. In addition to genetic, there are also environmental factors and cultural differences. The aim of this study was to compare the morphological configuration of men’s body of Slovak and Saudi Arabian soccer players and find out the differences between soccer players in different the playing positions . The study sample consisted of 50 Slovak soccer players aged 19-26 years (21.28±1.46), including 18 defenders, 13 forwards, six goalkeepers, and 13 midfielders, and 50 Saudi Arabian soccer players aged 18-25 years (20.12±1.77), including 16 defenders, 20 forwards, four goalkeepers, and 10 midfielders. The used Heath-Carter method categorize people into 13 groups according to the predominant physical component. The results indicated that soccer players differed among themselves according to playing positions. Slovak defenders and forwards were balanced mesomorphs, Slovak goalkeepers were endomorphic mesomorphs and central type was the predominant in Slovak midfielders. Almost all Saudi Arabian soccer players were predominantly mesomorph-endomorphs, with the exception of the defenders who were endomorphic mesomorphs. On average, the predominant somatotype of Slovak soccer players was balanced mesomorph (2-8,4-1,2-4), and of Saudi Arabian soccer players mesomorph-endomorph (3-8,4-3,1-4). It seems that the somatotype of soccer players varies depending on the country as well as the playing position. Therefore, it is necessary to examine anthropometry also with regard to geographical and cultural differences. In addition, regular evaluation of soccer player’s somatotype can help coaches implement exercise elements that would probably increase players’ sports performance.

The Homo naledi discovery introduced questions that had not been previously posed regarding fossil finds. This is because, apart from their fascinating physiology, they seemingly deliberately disposed of their dead in a ritualised way. Although this theory may still be disproved in future, the present article provisionally accepts it. This evokes religious questions because it suggests the possibility of causal thinking, wilful and cooperative behaviour, and the possibility that this behaviour entails traces of proto-religious ideas. This poses the challenge to develop a hominin hermeneutics that endeavours to reconstruct the possible motivation behind this action. The relatively larger brain with its enlarged Broca’s area suggests the possibility of a sophisticated communication system and an enhanced way of dealing with emotion. We know that almost all life forms have some form of awareness and that more sophisticated degrees of consciousness may be present in the higher primates. Various ‘clues’ are investigated to try and understand the H. naledi phenomenon: lessons from chimpanzee studies, the implications of tool making for hominin development, the possibility of a proto-language and the role symbol formation may have played. The H. naledi case also indicates on a theological level that religion is natural. Some attention is given to this thesis. Biological and environmental factors come into play to illuminate biological factors like emotion and higher cognition without which religion would not be possible. Sophisticated cognition is coloured by affect (basic emotions are typical of all mammals) and this makes some form of reflection on the fate of loved ones who have died a strong possibility.

AbstractThe purpose of the present study was to examine the 10 value types from the Portrait Values Questionnaire (PVQ; Schwartz et al., 2001) both at the phenotypic (observed) level as well as the genetic and environmental level. Australian twins (N= 695) completed the PVQ as part of a larger questionnaire battery. Nine of the value types were found to have a genetic component with heritability estimates ranging from 10.8% for power to 38% for conformity. The achievement scale was best explained by environmental factors. The interscale correlations were found to range from –.02 to .70 at the phenotypic level. Of these 45 correlations, 16 were found to be explained by overlapping genetic factors and almost all (41) were found to have significant unique environment correlations.

Baited traps with a 5 mm diameter opening were deployed 9 cm off the seabed in the Cape d'Aguilar Marine Reserve, Hong Kong. In contrast to analogous studies from boreal waters, lysianassoids accounted for 0.5% of the total number of trapped hyperbenthos. Species of Tisbe (Copepoda: Tisbidae), Ceradocus (Gammaridea: Melitidae), Nebalia (Leptostraca: Nebaliacea), unidentified benthic ostracods, Neanthes cricognatha (Polychaeta: Nereidae) and a species of Lepidepecreum (Amphipoda: Lysianassoidea) were caught in a decreasing order of numerical importance. A spatial segregation of trapped fauna was identified between the reserve's shallow Lobster Bay (<–2 m Chart Datum (CD)) and deeper-waters (between –6 and–17 m CD) outside it. Ceradocus sp. monopolized the trapped fauna in the former area, while the other species were caught almost exclusively from the latter. Insignificant Ceradocus sp. catch differences between baited and control traps suggested that they functioned only as ‘habitat traps’ for this species. Almost all other organisms attracted to the bait were hyperbenthic scavengers. Their absence from the shallows might be due to the coarser and lower organic contents of the sediments, also related to faster flow rates here. Finally, we confirm that in subtropical Hong Kong, lysianassid amphipods are not as significant hyperbenthic scavengers as they are in boreal waters.

This paper seeks to challenge the dominant paradigm on housing only as an standarized object for living. For the urban poor, urbanity is conceived as petromax that attracts them to come to the city striving for fortune. What really matters is how they could get access to space or “a piece of land” (lahan) in the city,which may not mean it housing let alone home. A house is imagined as a shelter that lets them engage with economic activities within. It does not have all the basic facilities needed to raise a healthy family as understood and believed by politicians, bureaucrats and those in the property business. The research method used in this projects in order to discover the metaphysical phenomena of invisible housing is a grounded method. The idea of invisible housing is uncovered through an emic approach of investigations to the respondents. Findings have shown that the urban poor perceive urbanity as space of existence. Open lahan or open urban land (such as on river bank) perceived as “no man’s land” for them to utilize.
