Abstract

Wood processing industry waste consists of waste produced by the plywood industry, sawing and woodworking consisting of ends, blades, peelings, chips and sawdust. The use of wood waste is not utilized by the furniture industry and one of the solutions to its utilization by processing wood waste into activated charcoal. Activated charcoal can be made from all carbon-containing materials both organic and inorganic provided that the material is porous. Bangkirai, Rengas and Sengon wood waste as materials used in this study were carbonized first then activated charcoal. The quality test of activated charcoal carried out includes yield, air content, ash content, volatile matter content, carbon content, absorption of benzene, absorption of iodine and absorption of methylene blue. Overall, the results of testing the quality of activated charcoal did not all meet the requirements of SNI 06-3730-1995. The quality of activated charcoal from Rengas wood has the best quality (>456.59 mg /g) of all needs because the highest iodine absorption capacity according to Kimia Farma (KF) standards requires (> 426.5 mg/g). Rengas wood activated charcoal to bore wells improves the quality of drinking water No. 416/ Menkes / Per/IX /1990 except turbidity.

Abstract

Red Meranti was a commercial wood that is widely used as a raw material for the timber industry (plywood and sawmill industry), and generated a lot of waste. Currently, the utilization of red meranti waste has not been utilized optimally. One of the optimizing utilization of that waste was for developing a Particleboard with the citric acid natural binder. The objective of this study was to determine the bonding properties of Sawmill Waste Red Meranti Particleboard bonded with a Citric Acid Natural Adhesive. Citric acid was dissolved in water with the concentration of the solution adjusted to 60 wt%. This adhesive solution was sprayed onto the 40 mesh (coarse) and 40 mesh (fine) particles at 10% and 20% resin content based on the weight of oven-dried particles. Each mixture was then hot pressed at 110°C for 15 min under 50 kg/cm² pressure. Density and dimension targets were 0.7 kg/cm³; 30 × 30 × 1 cm. Each experiment was performed in triplicate, and the average value and standard deviation were calculated. The results showed that the interaction of particle size and adhesive content had a very significant effect on density, internal bonding, and screw-holding strength and had no significant effect on moisture content, thickness swelling, and modulus of rupture (MOR). Based on the SNI 03-2105-2006, the physical properties that meet the standard were moisture content and. Meanwhile, the mechanical properties of sawmill waste red meranti particleboard have not met the SNI 03-2105-2006. Kata kunci (Keywords): Sawmill waste, red meranti waste, citric acid, natural binder.

Abstract

Karakteristik hidrologi daerah aliran sungai (DAS) berperan penting dalam mendukung ketersediaan air dan mencegah terjadinya banjir dan kekeringan.   Penelitian ini bertujuan untuk menganalisis karakteristik hidrologi DAS Ilahan.  Pengumpulan data dilakukan dengan pengambilan sampel tanah, peta tutupan lahan, peta lereng, data iklim, dan debit air DAS Ilahan.  Data yang terkumpul kemudian diolah menggunakan pemodelan SWAT (Soil Water Assesment Tools) untuk menganalisis karakteristik hidrologi, meliputi: surface runoff, lateral flow/sub surface runoff, baseflow dan mensimulasi skenario tutupan lahan terhadap karakteristik hidrologi di DAS Ilahan.  Hasil penelitian menunjukkan karakteristik hidrologi DAS Ilahan: surface runoff sebesar 379,30 mm; sub surface runoff sebesar 707,05 mm; baseflow sebesar 348,01 mm.  Skenario tutupan lahan menggunakan RTK-RHL tahun 2014-2029 seluas 430,57 ha, dengan merubah tutupan lahan menjadi kebun campuran kerapatan tinggi.  Hasil skenarionya diprediksi merubah karakteristik hidrologi DAS Ilahan yaitu surface runoff menurun menjadi 291,12 mm; lateral flow/sub surface runoff meningkat menjadi 759,34 mm; dan baseflow meningkat menjadi 377,86 mm.  Perubahan tutupan lahan dengan skenario RTK-RHL menyebabkan karakteristik hidrologi DAS Ilahan menjadi lebih baik dari kondisi eksisting. Namun kondisi ini belum optimal memperbaiki karakteristik hidrologi DAS Ilahan, sehingga direkomendasikan dilakukan pemutakhiran RTK-RHL di DAS Ilahan.

Abstract

Energy potential and reserves such as petroleum and natural gas available in the bowels of the earth are running low, so alternative energy is needed. Charcoal briquettes are one of the non-oil and gas energy sources that have a high enough potential to meet future needs other than oil and natural gas. Sawmills in the furniture industry produce sawdust of sungkai (Peronema canesens) and ironwood (Eusyderoxylon zwageri) wood powder which can be used as raw materials for making charcoal briquettes. The purpose of this study was to determine the quality of charcoal briquettes produced from the waste composition of sungkai sawdust and ironwood sawdust. The average test results for the physical, chemical and mechanical properties of each test treatment complied with SNI (01-62365-2000) except for density and volatile matter. The best quality of charcoal briquettes was found in treatment K1 (0% Sungkai and 100% Ulin) with density of 0.57 (g/cm3), compressive strength of 65.76 kg/cm2, moisture content of 4.08%, volatile matter content of 29 .76%, ash content 1.20%, fixed carbon content 62.77% and calorific value 6869.71 cal/g.

Abstract

Good germination of rattan jernang (Daemonorops draco Blume) seeds will increase germination power, germination rate, and germination value. However, there are still obstacles to germination, because the jernang rattan seeds have a dormancy period. Soaking in Atonic Growth Regulatory Substances (ZPT) is one method that can be used to break thedormancy period of seeds. This study aims to determine the dose and soaking time on the germination value of jernang rattan seeds (D. draco Blume). The study used four treatments and 3 groups/replications. The treatment in this study was the dose of ZPT Atonik, namely 50 CC/Liter, 80 CC/liter, 120 CC/liter, 150 CC/liter. Grouped by immersion time, 24 hours, 48 ​​hours and 72 hours. The results showed that the best germination percentage of German rattan (D.draco Blume) seeds were treated with ZPT Atonik dose of 120 cc/liter and soaked for 48 hours with a percentage of 100%. The best seed germination rate was at 150CC/liter treatment and 24 hours of soaking time, which was 50%/day. The highest germination value was found in seeds treated with ZPT 120CC/liter and soaking for 48 hours with an average of 0.0036%/ day. The conclusion of this study is that the ZPT Atonik dose of 120 CC/liter and 48 hours of soaking time has an effect on the percentage of germination power and germination value, while the ZPT dose of 150 CC/liter with 24 hours of soaking time increases the germination rate
