Abstract

This article presents the mechanical properties of coir-angustifolia Hawagave fiber hybrid composite. Prior to form composite, these fibers were soaked in 5%w/v NaOH solution during 24 hours. Coir fibers were twisted and composed one direction like mat and agave fibers were also composed one direction and formed mat. Epoxy resin was used as matrix in this hybrid composite.The hybrid composites were manufactured using hand layup technique followed by compression molding. The variation of fraction volume of coir fiber and agave fiber was 10:20, 15:15 and 20:10 respectively. The tensile strength, tensile modulus, flexural  strength and flexural modulus were evaluated. Fracture tensile was analysed by Scanning Electronic Microscopy (SEM). Result showed that 15%Vf coir and 15% Vf agave fibers on the hybrid composite yield high tensile strength, tensile modulus and flexural modulus compared to other fraction volume. SEM analysis exhibits that all fraction volume variations on the composite tend to undergo fiber fracture without pull-out and matrix damage.Keywords : hybrid composite,  coir fiber, angustifolia Haw agave fiber, matrix, mechanical properties.

Abstract

Natural fibre composites have been developed for some applications. One of potential natural fibre for composite is angustifolia Haw Agave fibre.  In this research, the tensile strength and flexural strength of agave fibre composite with variations of fibre length were determined. Fibre agave (treated and untreated) with 1 cm, 3 cm and 5 cm length was used as reinforced composite.    The results showed that the maximum tensile strength of agave fibre composite with untreated fibre occurs in 5 cm length, meanwhile with treated fibres the tensile strength tends to similar for each fibre length; and agave fibre with 5 cm length  as reinforced composite has higher flexural strength than other fibre lengths for treated and untreated fibres.

Abstract

This writing is designed to investigate prospects and challenges facing Syariah Obligation (sukuk) in Indonesia. In this study, we found Syariah obligation (sukuk) development have good prospect. There are factors supporting Syariah obligation (sukuk) in Indonesia, some of which are significant population, government support, and domestic economic stability over percent per year, flow of fresh fund by Middle East, and making complete regulatory framework, as well as the rise of global Syariah market. Notwithstanding sukuk potential, some challenges are exist, for examples, drawback of regulation, uncertainty of taxation, most of Syariah financial products are “debt-based” or “debt-likely”, less investor understanding of Syariah obligation instrument, and not quite conducive investment climate  and complicated bureaucracy.  -----Tulisan ini bertujuan untuk mengkaji prospek dan tantangan obligasi syariah (sukuk) di Indonesia. Pada penelitian ini, ditemukan bahwa prospek pengembangan obligasi syariah (sukuk) di Indonesia cukup baik. Terdapat beberapa faktor yang mendukung keberadaan obligasi syariah (sukuk) di Indonesia, antara lain: jumlah penduduk yang banyak, dukungan dari pemerintah, Stabilitas perekonomian dalam negeri, di atas persen pertahun, mengalirnya dana segar dari timur tengah, dan regulatory farmework yang cukup memadai, serta bangkitnya pasar global syariah. Meskipun potensi sukuk cukup baik, tetapi tetap saja memiliki sejumlah tantangan, antara lain: adanya kelemahan dari aspek regulasi, ketidakpastian dari segi perpajakan, kebanyakan produk keuangan syariah bersifat” debt-based”atau “debt-likely, kurangnya pemahaman oleh investor terhadap instrumen obligasi syariah, dan iklim investasi yang kurang kodusif serta birokrasi yang berbeli-belit.

Abstract

Corn production obtained was 6.4 t ha-1. This condition was very promising though still below the maximum national production. The aapplications of subsurface drainage was still not optimumum due to the supply of water from the main system was not the same because of the soil physical properties diversity and topography differences.This condition implied that installation of sub-surface drainage at dry season had function as water retention, not as water discharge. There-fore, network function was inverted from water discharge into water retention. It had impact on the development of optimum water surface that flow in capillary mode to fulfill the crop?s water requirement. Farming constraint at tidal lowland area is about water management related to the nature of excessive water during wet season and insuf-ficient water during dry season. This field research objectives was to find out the corn crop culti-vation in August 2014 which entered dry season.The iinstallation of subsurface drainage that previously had functioned as water discharge was converted into water retention. The research results showed that corn had grown well during peak dry season period (October) in which water table was at ?50 cm below soil surface, whereas water table depth was dropped to ?70 cm below soil surface in land without subsurface drainage.
