Abstract

Plantations of the palm in Indonesia is very large included Riau Province. It cause the palm trunk be the most waste and it has the potential to be utilized for manufacturing Wood Plastic Composite (WPC). Properties of the palm trunk is different and it has many weakness. Knowledge of stem’s lignocellulose can be easier to modify suitable materials for compatibility between WPC components. The main objective of this study is to determine the percentage of palm trunk parts longitudinally, to determine the lignocellulose component before and after preparation using oxalic acid, to evaluate the effect of palm trunk parts longitudinally and ratio of wood flour/polypropylene to the properties and morphology of WPC. The composition of wood flour was 100 mesh as filler and polypropylene as matrix are 50/50; 60/40; 70/30 with mixture of 2% paraffin as plasticizer, 5% maleic anhydride (MAH) and 5% Benzoyl peroxide (BPO). The palm trunk was prepared using oxalic acid at 120oC for 15 minutes. WPC samples were prepared using internal mixer Labo Plastomill at temperature 170oC and rotor speed 80 rpm. Testing experiments were prepared to mechanical properties consists of tensile strength and elastic modulus (MOE) and physical properties consists density, water absorption and swelling thickness. Scanning Electron Microscopy was used as a morphology testing with 50x and 500x magnification. The results showed that each part of palm and ratio of wood flour/polypropylene gives an influence.

Abstract

Plastic waste is one of environmental problem especially in Indonesia. Conventional plastic is made from synthetic polymer that is made by petroleum which hard to recycle or break down by microorganism. Bioplastic is the answer of this problem. Starch is kind of natural polymer that can be used for bioplastic production because the sources overflow, renewable and ready degradable. However, starch have a bad mechanical characteristic. Cellulose as the strengthened has been proved to overcome the lack of starch. This research is aim to analyze the effect of composition and size of cellulose particle to get the best combination of bioplastic mechanical characteristic and morphology. Bioplastic was made by casting method where the taro’s starch, glycerol and cellulose are mixed. This research take variable on addition level of cellulose 6, 9, 12, 15%wt with cellulose fiber sizes of 100, 150 and 200 mesh. The composition with a good characteristic was 15%wt cellulose with the size 150 mesh with strength 7,595 MPa, elongation 11,379%, modulus young 66,465 MPa, water uptake 37,50%, and biodegradation is about 36,11% in one week.Keyword : bioplastic, casting, cellulose, glycerol, starch

Abstract

The COVID-19 pandemic that hit Indonesia had a significant impact on the industrial sector. One of them is the natural rubber industry which has experienced a decline due to export restrictions from natural rubber export destination countries. This has a direct impact on rubber farmers who suffer financial losses. The formation of a new natural rubber downstream industry for natural rubber modified asphalt is a solution to increase national rubber consumption without relying on exports. Therefore, the purpose of carrying out the asphalt title test based on natural rubber type crepe rubber is to evaluate technical feasibility and educate the public about using natural rubber for domestic needs. This service method consists of several stages: observing the absorption potential of natural rubber, analyzing technical feasibility, and evaluating the degree test of natural rubber modified asphalt. The degree test was carried out on the 10-meter road around the Faculty of Engineering, Riau University. The results of the degree test show that the modified asphalt raw material is based on crepe rubber, the asphalt sample marshall test that was held, and the core drill test meets the 2018 Highways standard. The degree test that has been carried out can educate the community and rubber farmers through APKARKUSI regarding natural rubber processing technology and compound making. Crepe rubber and the technology of making modified asphalt and applying modified asphalt for roads.

Abstract

The low density of mass and energy are the main reason for the underutilization of great potential of Empty Fruit Bunch (EFB) as a raw material of alternative and renewable fuels. The using of bintaro fruit as co-firing and treatment of torrefaction – densification processes were believed to increase the density of mass and energy of the EFB biopellet. This study aims to determine the effect of residence time, compaction pressure, and addition of bintaro fruit to the characteristics of EFB biopellet according to ISO 17225-6 standards. Biopellet manufacture was carried out two processes sequence, namely the torrefaction process and the densification process. The torrefaction process was carried out at 275oC with residence time variations 30, 45, and 60 minutes. The densification process was carried out without binder with compaction pressure variations 30, 40, and 50 bar. The addition of bintaro fruit was intended as co-firing of EFB at a ratio 70:30. The best characteristics of biopellet were obtained under conditions of 60 minutes residence time and 50 bar compaction pressures with 3.00% of moisture content, 7.90% of ash content, 8.70% of volatile content, 80.40% of fixed carbon content, 4719.59 cal/gr of heating value, and 1.28 gr/cm3 of density. Characteristics of moisture content and volatile content decreased while ash content, fixed carbon content, and heating value increased with increasing residence time. Characteristics of density increased with increasing compaction pressure. Characteristics of proximate and heating value increased while density properties of biopellet decreased with the addition of bintaro fruit as co-firing.

Abstract

Abstrak: Penelitian ini bertujuan untuk mengkaji pengembangan moderasi beragama di lembaga pendidikan Islam (pesantren) melalui sistem pendidikan dan pengajaran serta praktik nilai-nilai yang ditanamkan Pondok Pesantren Bali Bina Insani. Jenis penelitian ini adalah penelitian kualitatif, sehingga data penelitian ini didapat dengan cara observasi, wawancara, dokumentasi dan penelitian terdahulu. Hasil penelitian menunjukkan bahwa sistem pendidikan dan pengajaran yang diterapkan yaitu dengan mengadopsi Kurikulum Kementrian Agama, Kurikulum Kementrian Pendidikan dan Kebudayaan serta Kurikulum Pesantren serta menerapkan multibahasa dalam kehidupan sehari-hari yaitu Bahasa Arab dan Bahasa Inggris. Dalam membentuk moderasi beragama ditengah-tengah masyarakat multikultural praktik nilai-nilai yang di internalisasikan Pondok Pesantren Bali Bina Insani yaitu Nilai Tasamuh yang dapat dilihat dari komitmen pimpinan dalam mengelola keragaman di internal pondok pesantren, Aulawiyah dengan tidak memasang pengeras suara di pondok pesantren, Musawah dengan tidak memandang kedudukan di pondok pesantren berdasarkan keyakinan, Tahaddur yang menjunjung tinggi adab terhadap satu sama lain serta I’tidal yang tidak mencampuradukkan perbedaan dan keyakinan.
