Oil palm shell is one of biomass-wastes which is abundantly found in palm oil industries. Its economical value can be enhanced by converting it into hydrochar using a hydrothermal carbonization process (HTC). In this study, preparation of oil palm shell hydrochar was performed and the material was used as adsorbent to remove methylene blue from waste water. Effects of HTC temperature, KOH activator concentration, and adsorption time were studied. Functional groups of hydrochar were evaluated by Fourier transform infrared (FTIR) spectroscopy. Meanwhile, the uptake capacity of hydrochar to adsorp methylene blue was measured by using UV-Vis spectrophotometer. The results showed that dehydration and decarboxylation reactions took place more progressively at the higher temperature of HTC. It was also found that activation process resulted higher removal efficiency of methylene blue. The highest adsorption capacity (16.58 mg/g, with removal efficiency 99.51%) was obtained by hydrochar prepared by HTC 270°C, KOH 1.5 N, and carried out for 80 minutes.Keywords: activator; adsorption; hydrothermal carbonization; methylene blue; oil palm shellA B S T R A KTempurung kelapa sawit merupakan salah satu limbah biomassa yang jumlahnya cukup melimpah di industri minyak kelapa sawit. Nilai ekonomi tempurung kelapa sawit dapat ditingkatkan, salah satunya melalui hydrothermal carbonization process (HTC). Dalam penelitian ini, hydrochar dari tempurung kelapa sawit dibuat dan digunakan sebagai adsorben untuk menjerap metilen biru dari limbah cair. Dalam hal ini, akan dipelajari pengaruh suhu HTC, konsentrasi aktivator KOH, dan durasi adsorpsi. Gugus fungsional hydrochar dianalisis dengan FT-IR spectroscopy, sementara itu kapasitas adsorpsi terhadap metilen biru diukur dengan spektrofotometer UV-Vis. Hasil percobaan menunjukkan bahwa reaksi dehidrasi dan dekarboksilasi pada kondisi hidrotermal terjadi lebih cepat pada suhu HTC yang lebih tinggi. Selain itu, proses aktivasi dengan KOH terbukti dapat meningkatkan efisiensi penyisihan metilen biru. Kapasitas adsorpsi maksimum sebesar 16,58 mg/g (dengan efisiensi penyisihan 99,51%) dihasilkan dari adsorpsi dengan menggunakan hydrochar yang diperoleh dari HTC suhu 270 °C, diaktivasi dengan KOH 1,5 N dan durasi adsorpsi selama 80 menit.Kata kunci: adsorpsi; aktivator; karbonisasi hidrotermal; metilen biru; tempurung kelapa sawit

Test Result

The purpose of this research is to know the influence of pressure and use of conplast against mechanical properties which are a Modulus of Elasticity (MOE) and Modulus of Rupture (MOR) of plasterboard. The study is done because still low quality of plasterboard made from a mixture of ashes of oil-palm shell especially of the mechanical properties compared to the controls. The method of this reserach used variation of printed pressure and the addition of conplast. Test result is obtained that the highest value of Modulus of Elasticity (MOE) 90875.94 Kg/cm2, Modulus of Rupture (MOR) 61.16 Kg/cm2 and density values in generally good printed at the pressure 60 g/cm3 and the addition of conplast 25% as well as the composition of the ash of palm shell oil 40%: limestone 40%: cement 15%: fiber 5% and 300 mL of water. ABSTRAK Tujuan dari penelitian ini adalah untuk mengetahui pengaruh tekanan dan penggunaan conplast terhadap sifat mekanik yaitu kuat lentur dan keteguhan patah eternit berbahan dasar abu cangkang sawit. Penelitian ini dilakukan karena masi rendahnya mutu eternit berbahan campuran abu cangkang sawit dari bolier khususnya sifat mekanik dibandingkan dengan kontrol. Metode penelitian yang digunakan adalah dengan variasi tekanan cetak dan penambahan conplast. Hasil uji diperoleh bahwa kuat lentur tertinggi sebesar 90875,94 Kg/cm2 dan keteguhan patah sebesar 61,16 Kg/cm2, yang dicetak pada tekanan 60 g/cm3 dan penambahan conplast 25% dengan komposisi  abu cangkang sawit 40 %: kapur 40 % : semen 15 %: serat 5 % dan air 300 mL.Kata Kunci :  Abu cangkang sawit, conplast, kuat lentur, keteguhan patah.

One of waste agriculture materials is oil palm shell ash. It has been producing in high quantity in palm oil mill, and for storage of that an investment requires. In this paper, an attempt has been made to analysis effect of oil palm shell ash on compressive and flexural strength of cement mortar. The compressive strength and flexural strength of cement mortar has been measured. To improve accuracy of work 50% cement and 50% fine sand has been proposed in cement mortar mix design. The results have been indicated that the effect of OPS ash on flexural and compressive strength of cement mortar is not same. The deflection, load sustainability and time to failure for compressive strength have independent fluctuation of flexural strength. The positive and negative effect of OPS ash on mechanical properties of cement mortar has been observed. The morphology of crack failure has not been investigated. The work can be continued with many waste agriculture materials. Keywords: waste agriculture, deflection, load sustainability, time to failure.
