Abstract

Human behavior is a part of the ecological system, therefore overcoming the ecological crisis and living resources need to explore human traditions, way of life and human behavior toward natural resources. Understanding and translation of human harmonious relationship with all elements along with other living beings is a form of human ecological intelligence. The objective of this study was to describe the traditions and coastal communities behavior that contains the value of ecological intelligence in coastal biodiversity conservation. The study was based on observation, focus group discussion and identification of Bajau coastal community tradition in their lives and livelihoods on fishing, as well as the behavior toward biological resources. Bajau coastal communities settled in three villages in Pohuwato regency, Gorontalo. There are two themes that contains the value of ecological intelligence of  Bajau communities in the conservation of biodiversity, namely; mamia kadialo in tradition of fishing, and fishing behavior. The prohibition in the tradition of mamia kadialo contains the value of conservation of biodiversity. Usage of simple equipment on fishing activities provide a positive ecological consequences for the conservation of coastal biodiversity.

Abstract

Saurauia Willd. is a genus of perennial plant or bush which usually found in highland forest or as rheophyte in rocky areas along the river bed. There are 12 species of this genus found in West Sumatera. The purpose of this research is to analyze the grouping of Saurauia species based on morphometric analysis and determine the pollination system based on pollen-ovule (P/O) ratio. The research has been conducted since September 2014 until December 2015 by using the self-collected specimen and Herbarium ANDA specimen. Morphometric analysis was applied to all 12 species which consist of 21 morphological characters and pollen–ovule (P/O) ratio was applied to 10 species. The results of this research are: generally the euclidian distance is ranged 7.35-14.73. The shortest one is S. cerea and S. laxa which d point is 7.35 and the longest one is S. cerea and Saurauia sp. which the d point is 14.73. Saurauia sp. is closely related with S. leprosa and S. bracteosa which are belonged to same sub cluster and having the same character which are glabrous leaf surface, acuminate apex and 5 similar sepals. Pollen-ovule (P/O) ratio determined the pollination system of Saurauia is xenogami.

Abstract

Agricultural activity can’t be separated from synthetic herbicide. Some synthetic herbicide use metsulfuron methyl as active ingredient that works to change chemical materials in weed’s tissues so able to exterminate the tissue or disordering physiological system that needed for survivability of weeds. Because of that effect a question arises whether this compound also can affect non target organisms like periphyton algae. Periphyton is a group of microscopic organisms that grows attached to surface of objects or water plants, not penetrate the substrate, staying or moving on the substrate surfaces. One of main compilers of periphyton community is algae. Periphyton algae in water has significant role to determining primary productivity and as bioindicator of water quality. Some research that has been done shows if some active ingredient in particular concentration significantly affects toward primary productivity of periphyton algae and able to inhibit growth of certain algae species. This research was conducted to find out effects of metsulfuron methyl herbicide on periphyton algae community structure. Parameters measured are concentration of chlorophyll a, density, richness, diversity, evenness, and domination indices also periphyton algae species identification. Research conducted in laboratory scale use samples taken from Rawa Pening Lakes, Semarang District, Central Java. Observation time is 21 days with herbicide exposure at 0, 0.05, 0.1, 0.2, and 0.4 mg/L. Results show that periphyton algae community structure more impacted by exposure period of herbicide actve ingredient metsulphuron methyl than concentration that used in research.

Abstract

Tropidolaemus wagleri commonly known as complex species who widely distributed at tropical areas in Southeast Asia. We predicted that widespread distribution may affect the morphological variation among different population geographycally. This study were conducted based on direct survey and sampling in the fieldwork. The study sites was divided into two categories based on Bukit Barisan range which streching from North to South Sumatra island consist of Padang, Padang Panjang in western part of Bukit Barisan, and Payakumbuh, Dharmasraya in eastern part of Bukit Barisan. In total 21 individual T.wagleri were analysed based on 20 mensural characters (morphometric) and 19 multistate characters (meristic). Male and female was analysed separately based on non parametric statistics Kruskall Wallis and Mann Whitney U Test. The relationship between population were analysed based on UPGMA tree and Principal Component Analysis (PCA) plot. The result showed the significant variation between female T. wagleri between western and eastern part of Buki Barisan range. In contrast, the variation has not detected among the population of T. wagleri male. The morphological character which showed the significant value are Head Length (HL) and Neck Scales Row (NSR). The west population of T. wagleri has more shorter Head Length (HL) and Snouth Length (SnL) than east population. Howefer, the west T. wagleri population has more number in Neck Scales Row (NSR) character than east population. The population of female T. wagleri in Padang Panjang has more close relationship to Padang than to female population T. wagleri in Dharmasraya based n UPGMA tree.

Abstract

Tomato (L. esculentum) is one of the most important vegetable crops produce in West Sumatra. In this province, tomato are cultivated at highland regions of Solok, Padang Panjang, Tanah Datar and Bukittinggi. Annually, the increasing demand of this crop comes from other provinces in Sumatra and Java. This opportunity stimulate tomato’s agribusiness activity in West Sumatra. However, the crop succumb to the most destroyed bacterial wilt disease caused by Ralstonia solanacearum. The aims of this study to select antagonist Pseudomonas fluorescent as a biological control agent against R.solanacearum. The candidates of antagonist P. fluorescetn were collected from diseased tomato with R. solanacearum’s symptom in several tomato’s plantations in West Sumatra. Study of the antagonist was conducted from March to July 2016 at the Laboratory of Microbiology, Faculty of Mathematics and Natural Sciences Andalas University. To find the antagonist work, each of the collected candidate was grown opposite R. solanacearum on Nutrient Agar medium. The result found that there were16 isolates of P. fluorescent occurred. The best antagonist ability amongst the candidates was from Pfi with diameter zone was 4,95 cm.Keywords: tomato, Ralstonia solanacearum, Pseudomonas fluorescens, biological control agent, Pfi

Abstract

Anthropogenic-origin forest disturbance has been known to increase the risk of invasion to native habitat. Invasive species caused problems for local ecosystems and their native species. The  research on the dynamics and autecology of invasive species Cyperus rotundus was conducted on anthropogenic disturbed Pohen mountain forest in Bali, Indonesia. Results showed significant changes in microclimatic variables from forest edge to interior. C. rotundus in Pohen mountain forest can be found in a road edge and forest exterior where sunlight is abundant and decrease in a more shady sites and absent under thick forest canopies CCA ordination analysis showed that C. rotundus in Pohen mountain forest tends to co-occur together with Imperata cylindrica and Bidens biternata. To be able to control potentially troublesome exotic invasive species, firstly we have to understand what factors limit their growth and development. Therefore this study is has important value because the data which from  result in studying invasive species autecology will act as baseline data that will be useful to generate management program including rehabilitation and restoration program. Key words: species dynamics, autecology, Cyperus rotundus, Pohen mountain forest, Bali

Abstract

Penelitian ini bertujuan unuk melihat gambaran histologi arteri dorsal penis tikus wistar (Rattus novergicus) yang dibuat hiperlipidemia dengan induksi pakan tinggi lemak yang dilihat dari segi diameter lumen serta ketebalan dinding endotelium arteri. Hiperlipidemia merupakan faktor resiko ateriosklerosis pada arteri penis penyebab disfungsi ereksi pada pria. Penelitian ini menggunakan rancangan randomized posttest only control goup design. Sampel tikus wistar jantan dewasa umur 3-4 bulan dengan kisaran berat badan 150 - 200 gram, berjumlah 10 ekor. Sebelum perlakuan, dilakukan adaptasi selama 7 hari. Setelah itu tikus sampel pada kelompok perlakuan dibuat hiperlidemia dengan diberi lemak babi selama 50 hari. Kemudian dilakukan pembedahan untuk preparat histopatologi pada posttest. Untuk mengetahui perbedaan ketebalan endotelium dan diameter lumen arteri pada kedua kelompok maka digunakan uji independent t-test. Hasil penelitian menunjukkan bahwa diameter lumen dan tebal endotelium arteri dorsal penis tikus wistar antara kelompok perlakuan lebih rendah dengan kelompok kontrol. Perbedaan yang terjadi bermakna secara statistik (p<0,05). Jadi dapat disimpulkan bahwa pemberian makanan tinggi lemak (hiperlipidemia) menurunkan diameter lumen serta ketebalan endotelium arteri dorsal penis. Kata Kunci: Arteri dorsal, Pakan Tinggi Lemak, Tikus Wistar
