Pengembangan Usaha Aneka Penganan Tradisional Minang Dalam Meningkatkan Ekonomi Masyarakat
No full textThere are so many home-based businesses in West Sumatra. One of them is to make traditional cakes typical of the local area. Minang Kabau have many culinary products that have been widely known. Starting small business with household business can be a successful business with many branches. However, not infrequently this business is well developed, and some even stopped. There are many weaknesses in this household business, from production to business management. Some problems are still using simple tool in production process , inefficient and unhygienic production layouts. Another problem is the packaging is simple and simplistic, unattractive the display of products and less professional management. The IbM's goal is to improve the professionalism of home-based cakes through factory lay-out improvements, coconut shell extract packaging, product sales / display counters, PIRTs, trademarks, bookkeeping, management, and product marketing. Key words: production, lay-out product, display product, bookkeeping, small and medium enterprise

First Maltese record of Stephanopachys quadricollis (Marseul, 1879) (Coleoptera, Bostrichidae)
No full textThree specimens of Stephanopachys quadricollis (Marseul, 1878) were recently found in Malta in UV light
traps and represent the first record of this species for this country. Although S. quadricollis is native to
the Mediterranean basin, it is not yet clear if these Maltese records are due to a natural population or to
an interception. Distributional, nomenclatural and biological data on this species are summarized, and a
new synonymy is established: Stephanopachys quadricollis (Marseul, 1879) = Stephanopachys quadraticollis

Kinerja Campuran Asphalt Concrete Wearing Course Mengunakan Aspal Modifikasi Dengan Limbah Plastik
No full text Abstrak Perkerasan jalan terutama pada perkerasan lentur sering mengalami kerusakan yang lebih cepat akibat beban muatan kendaraan. Penggunaan bahan tambah (additive) menjadi salah satu alternatif yang digunakan untuk mendapatkan kualitas lapis perkerasan yang baik. Penelitian ini bertujuan untuk mendapatkan nilai Kadar Aspal Optimum (KAO) dan mendapatkan kinerja VIM, VMA dan VFA campuran lapisan AC-WC dengan penambahan limbah plastik High Density Polyethylene (HDPE). Metode yang digunakan pada penelitian ini mengacu pada Spesifikasi Teknis Bina Marga 2018 Revisi 2 Divisi 6. nilai KAO dengan metode marshall sebesar 6,45% pada variasi 0% penambahan limbah plastik, 6,3% pada variasi 1% penambahan limbah plastik, 6,25% pada variasi 1,5% penambahan limbah plastik dan 6,2% pada variasi 2% penambahan limbah plastik. Berdasarkan hasil pengujian laboratorium nilai KAO Marshall yang didapatkan semakin menurun dengan penambahan limbah plastik dan penambahan limbah plastik 2% merupakan kadar terbaik yang dapat digunakan dalam campuran beraspal karena memiliki nilai VIM dan VMA yang rendah dan nilai VFA yang tinggi. Kata kunci: 1, Aspal 2, AC-WC 3, Limbah Plastik 4, HDPE 5 Marshall Abstract Road pavements, especially flexible pavements, often experience faster damage due to vehicle loads. The use of additives is one of the alternatives used to get a good quality pavement layer. This study aims to obtain the value of Optimum Asphalt Content (KAO) and to obtain the performance of VIM, VMA and VFA of a mixture of AC-WC layers with the addition of High Density Polyethylene (HDPE) plastic waste. The method used in this study refers to the Technical Specifications of Bina Marga 2018 Revision 2 Division 6. the KAO value with the Marshall method is 6.45% at 0% variation of addition of plastic waste, 6.3% to variation of 1% addition of plastic waste, 6, 25% in the 1.5% variation of the addition of plastic waste and 6.2% in the 2% variation of the addition of plastic waste. Based on the results of laboratory testing, the value of KAO Marshall obtained decreases with the addition of plastic waste and the addition of 2% plastic waste is the best level that can be used in asphalt mixtures because it has low VIM and VMA values and high VFA values.

Hawaiianische Käfer der Gattung Blackburnia (Coleoptera, Carabidae, Platynini) : ökologische Spezialisierungen und Implikationen für den Artenschutz
No full textThe Hawaiian Islands have arisen in isolation in the middle of the Pacific Ocean due to volcanism unleashed by interaction of mantle-deep thermal plumes with the overlying Pacific Plate (MONTELLI et al. 2004, ABOUCHAMI et al. 2005). This volcano “factory” has produced a consistently present string of islands increasing in age from the current Big Island of Hawaii (500,000 years old) northwestwardly to the island of Kure, estimated to be 28-30 million years old (CARSON & CLAGUE 1995). Successively colonizing and proliferating on these islands since Miocene time (LIEBHERR 2005), are beetles classified in the carabid beetle genus Blackburnia SHARP, 1878 (LIEBHERR & ZIMMERMAN 2000). The 132 known Blackburnia species are arrayed in four successive adelphotaxa. The monotypic subgenus Protocaccus LIEBHERR & ZIMMERMAN, 2000, adelphotaxon to the rest of the radiation, is represented by B. mandibularis LIEBHERR, 2000 of Kauai. The next-diverging clade is classified as subgenus Colpocaccus SHARP, 1903, and is composed of four flightcapable species. The last two adelphotaxa are the nominate subgenus Blackburnia and subgenus Metromenus SHARP, 1884. The former includes 52 species, and is based on a ground-plan ancestor that was capable of dispersal by winged flight. This clade exhibits the greatest anagenetic diversification of all four clades, with various subgroups exhibiting extensive modifications of the external cuticle, including thickened, ridged, and variously shaped pronota and elytra, as well as elongate legs, and extensive specializations of the male and female genitalia (LIEBHERR & ZIMMERMAN 1998, 2000). Taxa exhibiting cuticular modifications are all brachypterous, suggesting that loss of metathoracic wings was a requisite precursor to modification of body armature. All 75 species of subgenus Metromenus are characterized by brachyptery. These also exhibit various body forms however the member taxa are never characterized by the thickened cuticle and associated modifications seen among taxa of sg. Blackburnia. Monophyly of the latter three subgenera was corroborated using molecular sequence data (CRYAN et al. 2001), though basal relationships of the three clades were resolved so that Colpocaccus and Metromenus were construed as adelphotaxa. In this study, morphological characters, and ecological and genetic characteristics of the various clades compared. These comparisons illustrate the coordinated diversification of ecological and genetic traits, and how these are associated with different levels of speciation. These traits are then put in the context of species endangerment, assessed using biotic survey data started in the 19th Century, and continuing during present-day efforts to completely describe and characterize the Blackburnia fauna.Die monophyletische hawaiianische Gattung Blackburnia SHARP, 1878 umfasst 132 Arten und kann in vier aufeinander folgende Adelphotaxa unterteilt werden: Untergattung Protocaccus LIEBHERR & ZIMMERMAN, 2000 (1 Art, flugfähig); Untergattung Colpocaccus SHARP, 1903 (4 Arten, flugfähig); Untergattung Blackburnia (52 Arten, viele mit reduzierten Flügel, Flugfähigkeit aber im Grundmuster); Untergattung Metromenus SHARP, 1884 (75 Arten mit reduzierten Flügeln). Die phylogenetischen Beziehungen der Gattung zu anderen Taxa der Platynini beweisen, dass Blackburnia die hawaiianischen Inseln im Miozän kolonisiert hat, wobei Kauai die zuerst besiedelte Insel darstellt. Die ökologischen Spezialisierungen der einzelnen Arten spiegeln sich in den phylogenetischen Beziehungen der Arten wider. Arten der Untergattung Blackburnia besiedeln weniger Habitattypen im Vergleich zu Arten der Untergattungen Colpocaccus und Metromenus. Die Larven der Untergattungen Blackburnia und Metromenus entwickeln sich vergleichsweise langsam und einige Weibchen der Untergattung Blackburnia legen die größten Eier innerhalb der Platynini. Die größte morphologische und genetische Diversität findet sich innerhalb der Untergattung Blackburnia, was auf eine größere Fragmentierung der Populationen der betreffenden Arten hinweist. Die umfassenderen ökologischen Spezialisierungen der Arten der Untergattung Blackburnia können auf dramatische historische Populationsschwankungen innerhalb der Arten zurückgeführt werden. Anthropogene Einflüsse, wie die Degradierung spezifischer Habitattypen (mesische Acacia koa Wälder) und die Einschleppung von Neozoen (z.B. Formicidae und Isopoda), haben aber die Assoziationen zwischen den phylogenetischen Beziehungen und den ökologischen Spezialisierungen verwischt. Diese Einflüsse machen deshalb eine Voraussage des Gefährdungspotentials der Arten mit Hilfe der Ergebnisse der phylogenetischen Analyse unmöglich. Einige Arten, die noch im 19. Jahrhundert Bestandteil der Koa-Wälder auf Maui waren, sind seit Anfang des 20. Jahrhunderts nicht mehr nachgewiesen worden. Diese nicht mehr nachgewiesenen Arten, welche Bestandteil spezifischer ökologischer Assoziationen waren, können bei genauerer Betrachtung die Gefährdungskriterien der I.U.C.N. erfüllen. Das Fehlen phylogenetisch verwandter Arten macht die Gefährdung der Arten selbst, als auch die Gefährdung der Koa-Wälder als Ökosysteme deutlich
Permian productidina of Britain and Malaysia
No full textThe British Permian Productidina have not been revised in detail since 1858. In the present study some 2000 specimens from 29 localities in north east of England have been collected and prepared in the laboratory and used together with museum collections. The fauna consists of four species of Strophalosia, one new species of Eostrophalosia, six species of Heteralosia (four new), three species of Craspedalosia (one new), two species of Howseia, four species of Horridonia (one new) and two species of Spinohorridonia new genus. The Strophalosiacea and Horridoniinae are divided according to a new classification produced in this research. British Permian productidinid species are often strongly variable. Some variants suggest possible sexual dimorphism while others are probably of ecological forms. The fauna as a whole is unique and exclusive to the Upper Permian Zechstein Sea. The British Permian fauna shows major radiation periods during the early EZla Ca and early EZlb Ca. In conjunction with these radiations, the Productidina become divided into two distinct assemblages, marking two biozones introduced in this thesis, the Horridonia horrida and Strophalosia excavata biozones. Little is known of the Malaysian Permian Productidina. They comprise one species each of Strophalosia, Craspedalosia, Institella, Antiquatonia, Reticulatia, Echi- noconchus, Linoproductus, Siepanoviella, Striatifera, Liosotella (with new species), Marginifera?, Paucispinifera, Retimarginifera (with new species) and Costispinifera, two species of Dictyoclostus, Waagenoconcha and Echinauris and three species of Cancrinella. Lower Permian productidinids are associated with Artinskian fusulines and show links with the South Tethyan cold water fauna. Upper Permian producti dinids contain a mixture of North Cathaysian elements and the warm South Tethyan lyttoniid fauna. Variation occurs within some of the Malaysian species, but owing to lack of material, no final deductions can be made. Similarly, although significant differences are observed in Malaysian productidinid distributions, tabulation of biostratigraphic zonation is left until more data is available
