Abstract

This report deals with experimental study on the utilization of palm-tree bast as raw material for activated charcoal. In this regard, the main aim was to study the effect of concentrations of vaporized  NH4HCO3and (NH4)2C03 solutions as activating agents (in persentages) on properties of activated charcoal, and to evaluate its use for purifying ground waler In this regard. the vapors might consist of NH3, CO2, and H2O. The manufacture of activated charcoal involved two consecutive stages, i.e. charcoaling and activation. The charcoaling was performed on the palm-tree bast in a retort equipped with electrical heater, followed by the activation stage where by the inside retort temperature was increased to 850ºC. At this temperature, the vapors of both NH4HCO3and (NH4)2C03 were each passed into the retort al several concentrations (i.e. 0.0 %; 0.01%; 0.025%; 0.075%. and 0.1% of either vapor) for 90 minutes at pressure of 0.05 kg/cm2 and on completion the resulting activated charcoal was examined of their inherent properties.It was found out that the activated charcoal with NH4HCO3vapor at 0.01% revealed the most satisfactory properties with respect to its selection for purifying the ground water. The yield of activated charcoal at this vapor percentage was 15.99%, moisture content 0.10%, ash content 31.85%, volatile matter 24.85%, carbon content 43.21%, adsorptive capacity of benzene 13.33 %, of CHCl3  16.28%, of NH3 26.65%. of CCl4 26.64%, of iodine 799.5 mg/g, of methylene blue 136.10 mg/g and surface area 463.41 m2/g.           ·The ground water afler being purified with this selected activated charcoal revealed the improvement on its qualities. as shown by the decreases in Fe from 4.919 mg/l; to 0.00 mg/I, Zn from 0.031 mg/I to 0.00 mg/I, Mn from 7.780 mg/I to 6.16 mg/I; the increase in pH from 6.99 to 8.00 on and the more transparent in its color.

Abstract

The experiment has been conducted on utilizing different types of charcoal as growth-stimulating agents by adding each of them to the growing media (i.e. soil stuff) of red pepper plant; and subsequently evaluating their effects on its growth characteristics/ responses. There were three types of agents used and added to the media, i.e. rice-husk charcoal, bamboo charcoal, and sawdust-mixed charcoal. respectively. For comparative purposes, were also measured the growth responses of the red pepper plant whereby its growing media were added with compost as well as the Bokasi rice-husk charcoal compost, besides the ones in the medium without the addition of any growth agents (as control). This experiment revealed some remarkable results. as follows:•              Additions of 5 % bamboo charcoal or l 0 % rice-husk charcoal could increase the height growth of the red pepper plant, in comparison with the one grown on the control medium:• Additions of 10 % rice-husk charcoal could increase the stem diameter of the plant by 11 % compared to the one on the control medium;•              Likewise, additions of 5 % and 10 % sawdust-mixed charcoal could each increase the stem diameter by consecutively l1 % and 10 %, in comparison with the control;•              Additions of 10 % bamboo charcoal brought about the best effect with respect to the increase in the number as well as the weight in red-pepper fruits in their first harvest (i.e. 3-month age), compared to the control:•              Additions of 10 % rice- husk charcoal, 5 % bamboo charcoal, and 10 % sawdust-mixed charcoal each brought about also the best effect with respect to the increase in the dry weight of the plant, i.e.consecutively 2.0, 2.0, and 1.8 times as such as that of the control;•                              Average amount of C02 absorbed by the red- pepper plants for 3 months was 0.10-0.88 gram per plant. The highest C02 absorption was achieved by the corresponding plants with addition of 10 % sawdust-mixed charcoal (i.e. 1.88 gram C02 per plant), followed in decreasing order by the ones added with 10% rice-husk charcoal and 10 % bamboo charcoal (i.e. 1.67 gram C02per plant and 1.34 gram C02 per plant, respectively).

Pemanfaatan kayu untuk berbagai produk seperti konstruksi bangunan, mebel, dan barang kerajinan perlu memperhatikan sifatnya, antara lain komponen kimia dan keawetannya, karena sifat ini saling berhubungan. Tulisan ini mempelajari komposisi kimia dan keawetan alami 20 jenis kayu dari berbagai daerah di Indonesia. Kandungan selulosa dianalisa berdasarkan metode Norman dan Jenkins, lignin berdasarkan SNI 14-0492-1989 dan zat ekstraktif berdasarkan SNI 14-1032-1989. Pengujian keawetan di lapangan dilakukan dengan pengujian kayu di bawah naungan. Pengujian keawetan tersebut dilaksanakan di kebun percobaan Cikampek, Jawa Barat. Pengamatan dilakukan setelah satu tahun pengujian, dengan cara menilai persentase kerusakan contoh uji yang disebabkan oleh organisme perusak kayu. Hasil penelitian menunjukkan kadar selulosa tertinggi pada jenis kayu Jaha (Terminalia arborea K. et. V.) (61,35%) dan terendah kayu bambang lanang (Michelia champaca L. var. pubinervia) (43,30%). Kadar lignin tertinggi 35,80% pada jenis kayu mahang putih (Macaranga hypoleuca Muell. Arg.) dan terendah 23,67% pada jeniskayu cempaka ( Elmerrillia papuana Dandy).Kadar zat ek straktif tertinggi (7,87%) ditemukan pada jenis kayu bawang (Azadirachta excelsa (Jack) M. Jacobs) dan terendah (1,52%) pada jenis kayu kandis (Pentaphalangium pachycarcum A. C. Smith.). Hasil penelitian keawetan alami kayu dari 20 jenis kayu terhadap organisme perusak kayu di lapangan, menunjukkan bahwa sebanyak empat jenis termasuk  awet (kelas II), enam jenis termasuk agak awet (kelas III), tiga jenis termasuk tidak awet (kelas IV) dan tujuh jenis termasuk sangat tidak awet (Kelas V).

Abstract

Study for improving the recovery and quality of activated charcoal through the combination of chemical and gasification treatments is presented in this paper. The material used in this experiments was charcoal derived from coconut shell. The material was immersed respectively in NaOH, Na2CO3, H3PO4 and ZnCl2 for 24 hours. Charcoal activation was conduted by using steam or combination of steam and mixed C02 and N2. The activated charcoal was produced in a stainless steel retort with electric heater at temperature of 900 - 1000°C.The result shows that the low dossage chemical treatment using NaOH at a concentration of 0,75%, or Na2C03 at a concentration of 0,75%, or ZnCl2 at a concentration of 5%, followed by activation by steam or the combination of steam and mixed C02 and N2.could produce good.quality activated charcoal which fullfils the commercial standard according to JIS. The produced charcoal attained the iodine adsorptive capacity of more than 1050 mg/g. By increasing the concentration of ZnCI2 to 10% or H3P04 to 20 %. followed by steam activation at 900°C - 1000°C, the iodine adsorptive capacity increased to more than 1200 mg/g.
