Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pemaparan cuaca terhadap kekuatan impak dari komposit rHDPE - serat pelepah salak. Fraksi volume pada komposit adalah 30%. Spesimen dibuat menjadi 3 variasi, yaitu spesimen rHDPE murni sebagai spesimen kontrol, komposit rHDPE berpenguat serat pelepah salak dengan perlakuan alkali, dan komposit rHDPE berpenguat serat pelepah salak tanpa perlakuan alkali. Pemaparan cuaca dilakukan selama 6 bulan. Untuk mengetahui kerusakan mikroskopis spesimen, pengamatan menggunakan Scanning Electron Microscopy (SEM) dilakukan. Setelah 6 bulan pemaparan cuaca, hasil pengujian menunjukkan bahwa perlakuan alkali hanya berpengaruh sebelum pemaparan cuaca. Sedangkan setelah dipaparkan cuaca, hasil antara komposit dengan perlakuan dan tanpa perlakuan alkali menunjukkan kesetaraan.

Abstract

Kawasan Riung terletak di pantai utara Pulau Flores, Provinsi Nusa Tenggara Timur, Ngada. Kawasan ini memiliki banyak pulau yang membentuk suatu kawasan pariwisata yang saling melengkapi satu sama lain dan membentuk sebuah taman laut surgawi yang unik. Banyak keunikan-keunikan yang ditawarkan oleh Riung, diantaranya keanekaragaman hayati, pantai berpasir putih dengan birunya air yang sangat jernih, hingga pulau-pulau yang masih “suci” dengan keunikan alamnya yang tidak dapat ditemukan di daerah lain. Namun, keindahan akan Riung belum banyak terekspos baik secara nasional bahkan internasional, sehingga wisatawan yang datang masih cenderung sedikit. Menindaklanjuti permasalahan yang ada maka tim Kuliah Kerja Nyata, Universitas Sebelas Maret (KKN UNS) merekomendasikan untuk dilakukan pemetaan dengan menggunakan drone sehingga potensi wisata yang ada di Riung bisa disebarkan dengan lebih menarik dan secara luas di dunia. Pemetaan dilakukan secara professional menggunakan drone yang telah dimodifikasi oleh tim KKN UNS, sehingga menghasilkan video yang menarik untuk disaksikan. Hasil pemetaan menunjukkan bahwa terdapat banyak lokasi wisata yang ada di Riung masih belum terekspos media, padahal lokasi ini mempunyai potensi besar untuk menarik wisatawan dalam maupun luar negeri. Beberapa lokasi tersebut adalah pegunungan, air terjun dan rumah adat yang ada di kabupaten Ngada, Nusa Tenggara Timur.

Abstract

Alkali treatment of natural fibers is one of the chemical treatments used to increase the exposed cellulose content through the removal of hemicellulose and lignin on the fiber surface. This study aims to investigate the effect of alkali treatment on the physical and mechanical properties of lantung fibers. The materials used in this          research consist of: lantung fiber (Artocarpus elasticus) with an alkali treatment process using 4% and 6% natrium hydroxide (NaOH) solutions and immersion time of 1 and 2 hours, at room temperature. The fiber neutralization process includes washing the fibers using fresh water and drying them at room temperature for 48 hours. Tests carried out include XRD test, SEM photo observations conducted at Balai Penelitian Teknologi Mineral, Lembaga Ilmu Pengetahuan Indonesia and fiber tensile test based on ASTM D 3379 standard. The results of XRD and fiber tensile test showed that alkali treated lantung fibers were effective in increasing the crystallization index (CI) value and fiber tensile strength. The highest CI values and fiber tensile strength were obtained at alkali treatment of 4% NaOH for 2 hours, respectively 85.42% and 228.5 MPa. The results of SEM photo observations showed that alkali treatment on the fiber surface could remove impurities based on the concentration of sodium hydroxide (NaOH) solution and soaking time. This shows that proper alkali treatment can increase the strength of lantung fibers.

Abstract

Acrylonitrile Butadiene Styrene (ABS) polymer is an example of a thermoplastic polymer that requires heat in its production process. ABS polymer also can be modified to increase strength against resistance, toughness, and heat resistance by adding MCC as a reinforcement to ABS composites. Extrusion is one of the established methods of polymer processing with filler and consequently disperses filler inside the polymer. Different speed shows different behavior of filler dispersion. Therefore, this study was conducted to know the effect of extruder screw speed variations on the mechanical, physical, and thermal stability of ABS/MCC composites. The compositions used in producing ABS/MCC composites are 96% for ABS and 4% for MCC. The production process uses screw extruder speed variations of 10 rpm, 15 rpm, and 20 rpm. ABS/MCC composite in the barrel and hot press use 160 °C for the temperature process. The highest tensile strength was obtained at 10 rpm variation for 14.2 MPa. Increasing the speed of the extruder screw causes a decrease in MCC content attached to ABS which reduces the mechanical strength. ABS/MCC composite density value decreased with the increased extruder speed, as evidenced by the increasing number of voids formed based on SEM testing.
