Pengembangan Material Bio-Komposit Serat Goni Sebagai Produk Home Decor
No full textPenggunaan material serat alam sebagai material komposit telah dikembangkan beberapa tahun belakangan ini. Serat goni merupakan serat yang di dapatkan dari tanaman Corchorus capsularis yang banyak ditemukan tumbuh di daerah tropis. Penggunaan serat ini di Indonesia masih belum digunakan dengan maksimal, masyarakat Indonesia kebanyakan hanya menggunakannya sebagai karung. Perancangan ini diawali dengan eksperimen pengolahan serat goni menjadi material bio-komposit untuk mencari berbagai karakteristik material untuk diaplikasikan pada produk seperti otomotif, furnitur dan home décor. Keunikan tekstur, bentuk, kekuatan dari material bio-komposit serat goni ini kemudian membuat penulis mengaplikasikan material ini menjadi produk home décor lampu dengan studi kasus pengaplikasian produk pada coffee shop. Pada perancangan ini, penulis melakukan eksplorasi material lembaran serat goni dan eksplorasi bentuk pada home décor lampu untuk menargetkan pasar kuliner coffee shop yang sedang berkembang di Indonesia. Pengembangan produk ini diharapkan dapat meningkatkan nilai jual dari serat goni dan pengembangkan serat goni menjadi produk hi-craft yang bermanfaat.

The use of natural fiber materials as composite materials has been developed in recent years. Jute fiber is a fiber obtained from the Corchorus capsularis plant which is widely found growing in tropical areas. The use of this fiber in Indonesia is still not fully utilized, most Indonesians only use it as a sack. The design begins with an experiment in processing jute fibers into bio-composite materials to find various material characteristics to be applied to products such as automotive, furniture and home decor. The uniqueness of the texture, shape, strength of the jute fiber bio-composite material then made the authors apply this material to a home décor lamp product with a case study of product application in a coffee shop. In this research, the author explores the material for jute fiber sheets and explores the shape of the lamp home decor to target the growing coffee shop culinary market in Indonesia. The development of this product is expected to increase the selling value of jute fiber and develop jute fiber into useful hi-craft products

The industrial world is currently developing material technology because it is a major factor in meeting the needs of materials with certain characteristics. Along with technological advances, it is now widely used of composite materials with natural fibers. Not only that, natural fibers are considered as materials that are environmentally friendly, renewable, non-abrasive, have precise resistance and easy processing.. According to Maya (2018) the production of 100% natural fiber based materials as a substitute for petroleum-based products is not an economical solution. A more feasible solution is to combine petroleum and biological resources to develop cost-effective products with diverse applications. In this research, jute fiber and fiberglass fibers with an epoxy matrix will be used. The variation used in this study is the stacking sequence of the hybrid composite layers of hessian cloth (G) and fiberglass (F). There are 3 variations of layers used in this study, in the first variation there are 5 layers of burlap with the stacking sequence G-G-G-G-G; the second variation has 3 layers of burlap and 2 layers of fiberglass fibers in the stacking order F-G-G-G-F; The third variation has 3 layers of fiberglass and 2 layers of burlap with the stacking sequence G-F-F-F-G. The angular orientation of the two materials used in this research is at an angle of 0°/90°. After the tensile test was carried out, the following values were obtained with jute variations for a tensile strength value is 57.27 MPa, a yield strength is 42.8 MPa, and a modulus of elasticity is 1933.37 MPa. The fiberglass-jute variation for a tensile strength value is 81.54 Mpa, a yield strength is 73.23 Mpa, and a modulus of elasticity is 2346.18 Mpa. Jute – fiberglass variations for a tensile strength value of 117.04 Mpa, a yield strength is 97.59 MPa, and a modulus of elasticity is 3322.63 Mp

Abstract
The term "critical ischemia of extremities" (critical limb ischemia) was first introduced by P.R.F. Bell in 1982 to refer to a group of diseases accompanied by pain in the legs at rest, trophic ulcers and distal necroses of the lower limbs. Critical ischemia of the lower limbs is a condition of almost complete cessation of arterial blood flow to the tissues of the lower limbs.
If the arterial blood supply is not improved, limb amputation becomes inevitable for all patients. Treatment of ischemia of the lower extremities should be complex and differentiated depending on the stage and features of the course of the disease. Modern approaches to the therapy of lower limb ischemia include conservative and surgical methods of treatment, all of which are aimed at improving blood flow in the affected limbs. In the article modern methods of stimulating angiogenesis in patients with lower limb ischemia and results are shown.

A break in neoliberal ideology? : A critical analysis of Bolivian elite discourse
No full textIm Dezember 2005, gewannen Evo Morales und seine Partei, die Bewegung zum Sozialismus (MAS), mit über 50 Prozent der Stimmen die Wahlen in Bolivien. Dieses war das stärkste Wahlergebnis einer Partei seit Einführung der Demokratie 1982. Morales wurde im Januar 2006 als der zweite indigene Präsident Lateinamerikas eingeweiht. Die Einweihungszeremonie war gleichzeitig ein Triumph der anti-neoliberalen Bewegung Boliviens, welche im Wasserkrieg im Jahr 2000 und im Steuer- und Gaskrieg im Jahr 2003 ihren Höhepunkt erreichte. Morales und MAS unterstützten die sogenannten Neoliberalen Kriege. Der Sieg der MAS und von Morales in den Wahlen regt Spekulationen an, dass der Neoliberale Konsens in der Elite, der Bolivien zwei Jahrzehnte lang regierte, gebrochen ist. Die Frage nach einem Konsenswechsel ergibt sich nicht nur von Morales’ und MAS Partizipation in den Neoliberalen Kriegen, sondern auch weil die MAS viele Forderungen der Proteste 2000 und 2003 in ihr Parteiprogramm aufgenommen haben. Während sich Morales’ anti-neoliberale Denkweisen offensichtlich in der bolivianischen Bevölkerung großer Beliebtheit erfreuen, ist es nicht erwiesen, dass sich diese Popularität auf die Elite des Landes erstreckt. Der potentielle Konsensbruch bezüglich des Neoliberalismus in der Elite entstand jedoch nicht von ungefähr. Im Gegenteil: er baute sich über die gesamte Geschichte Boliviens hinweg auf und wurde von den Rahmenbedingungen im Land begünstigt. Mit Hilfe der kritischen Theorie von Antonio Gramsci und Robert W. Cox, welche in Kapitel 2 vorgestellt wird, erforscht diese Magisterarbeit ob der Neoliberale Konsens in der Bolivianischen Elite gebrochen ist. Mit Unterstützung des Konzeptes, dass Geschichte und Produktionsbeziehungen Gesellschaften und die Gegebenheiten in ihnen den hegemonialen Diskurs formen, stellt diese Arbeit in den Kapiteln 3 Boliviens Geschichte bis dato dar und bespricht in Kapitel 4 wichtige Themen der aktuellen Bolivianischen Politik und Wirtschaft. Die Umsetzung der neoliberalen Ideologie und Richtlinien in Bolivien wurde von den USA, den hegemonialen Institutionen (der Internationalen Währungsfond und der Weltbank) sowie der sich in der Regierung abwechselnden Elite propagiert und implementiert. Die neoliberalen Programme der 1980er und 1990er wurden trotz bitteren Protesten seitens der Bevölkerung beibehalten, die sich gegen die negativen Konsequenzen der Programme wehrten. Da die kritischen Theorie Konflikte als Mechanismen sieht, die Machtverhältnisse verändern und einen Hegemon/ein hegemoniales System stürzen können, werden auch die Neoliberalen Kriege Boliviens besprochen. Insbesondere im Steuer und Gaskrieg 2003 baute sich ein anti-hegemonialer Diskurs auf. Dieser Konflikt, in dem die MAS mitagierte, wird besonders begutachtet weil er den Präsidenten Gonzalo Sanchez de Lozada (der neoliberale Kopf Boliviens) stürzte. Auf diesen Erkenntnissen basierend, wird in Kapitel 5 die Zeitungsanalyse vorgestellt. Diese wurde in zwei Zeiträumen vorgenommen: 2. bis 19. Oktober 2003 und 22. Januar bis 19. Februar 2006 (erster Monat der MAS-Regierung). Es wurden drei Zeitungen analysiert, welche je eine politische Strömung in der Bolivianischen Elite repräsentieren (La Prensa, konservative Tageszeitung; La Epoca, moderate Wochenzeitung, El Juguete Rabioso, ein alle zwei Wochen erscheinende linke Zeitung). Die Befunde der Zeitungsanalyse zeigten, dass die Bolivianische Elite sich sowohl gegen die anti-neoliberale Politik der MAS wendet, aber auch den Neoliberalismus und die Internationalen Finanzinstitutionen den Rücken gekehrt hat. Sie bewies auch, dass die Elite im Jahr 2003 erneut die Massen zu ihrem eigenen Vorteil missbrauchten, in dem sie ihre Wut, die gegen die Privatisierung der Gas Reserven gerichtet war, auf den regierenden Präsidenten (Sanchez de Lozada) umlenkten. Insofern zeigte die Zeitungsanalyse auch, dass ohne die Zustimmung der Elite in Bolivien ein friedlicher Systemwechsel unwahrscheinlich ist. Wie im Endfazit (Kapitel 6) beschrieben wird, hofft die bolivianische Elite, dass sich die MAS und Morales in inner- bzw. zwischen-parteilichen Scharmützeln verfängt, damit sich in der Zwischenzeit eine Alternative zwischen anti-hegemonialen und hegemonialem Diskurs findet, welche den Reichtum und die Macht der Elite erhält. Dies dürfte sich als schwierig erweisen, weil die politische Mitte Boliviens leer steht
The Effect of Graphic Organizers and Instructional Scaffolding on Argumentative Writing Performance Among TESL Undergraduates
No full textThe present study investigated the effect of graphic organizers and instructional scaffolding on argumentative writing performance among TESL undergraduates. The study employed a quasi-experimental research using the pre-test and post-test design involving 90 TESL undergraduates being placed equally in three different groups underwent lessons on argumentative essay writing using different delivery modes,
modes comprising of four stages of learning for a duration of four weeks. During the intervention period, three small groups of TESL undergraduates from the GOIS and GONI delivery modes were video-recorded to investigate on how they communicate in their groups. After the intervention, a semi-structured interview was carried out. A total of 9 students (GOIS, n=3; GONI, n=3; NGNI, n=3) were interviewed and the interviews were audio-recorded. The one-way ANCOVA was used to analyse the argumentative writing performance among the TESL undergraduates. The percentages were used to compare the overall percentages of Comm between the GOIS and GONI delivery modes while the qualitative data from the semi-structured interview of the three delivery modes were analysed using the constant comparative approach. Results showed that the group which underwent the GOIS delivery mode performed significantly better in the overall argumentative essay writing performance (p<.05) compared to their counterparts in the GONI and NGNI delivery modes. Additionally, in terms of the overall frequency of conjunctions and overall frequency of argumentative elements, the results indicated that both the GOIS and GONI groups performed significantly better (p<.05) than the NGNI group. In terms of overall percentages of , the GONI group outperformed the GOIS group. The findings from the semi-structured interview revealed that the GOIS group experienced learning better compared to the GONI and NGNI groups. The research confirmed that the GOIS and GONI delivery modes are effective in enhancing argumentative writing performance among TESL undergraduates. In line with this, the research ends with a recommendation for educators to adopt these delivery modes in t argumentative writing skills are enhanced.
