Abstract

Community empowerment has been carried out at the Kumala Lestari Islamic boarding school, located in Sukaresmi Village,Cianjur Regency, Indonesia. The community was involved in the manufacture of bioactive compostable charcoal (ARKOBA) andits application in agricultural areas. The study was conducted through comparison of rice planting using chemical fertilizers-pesticidesand those with ARKOBA-liquid smoke. The yield amount was measured by paddy crop productivity per hectare after 4 monthperiod. The study was conducted by production of biochar from sawmill waste using a modified drum reactor. The reactor temperaturewas set into 400–450°C, while the retention time was set into 6 hours. The process produces charcoal and liquid smoke.ARKOBA production was carried out by mixing compost: charcoal: activator, with a composition of 85%: 10%: 5%. Meanwhile,the ARKOBA dose was set to 400 kg/1000m2. The result shows that the productivity of rice threated was higher than those ofchemical fertilizers. Rice productivity was recorded at 3.2 tons/ha against 2.98 tons/ha in the Ciranjang and 4 tons/ha comparedto 3.1 tons/ha in the Sukaresmi demonstration plot. Mixing ARKOBA and liquid smoke threatment provides a surplus ofaround 7.4–29% than chemical applications and becomes recommended technology for increasing rice productivity.

Abstract

Forests as a place for carbon sequestration will be a source of emissions if there are no more photosynthetic plants to store carbondioxide (CO2) gas. CO2 gases that spreads in atmosphere can affect global climate change. Uncontrolled timber harvesting innatural forests has a negative impact on the potential for carbon absorption and CO2 emissions. This study aimed to analyze thepotential for carbon storage and emission due to felling in natural forests. The research method was carried out destructively andnon-destructively using data on potential stands before felling and the potential for trees to be felled on three logging compartmentsby making nine sample observation plots (PCP) in three selected felling plots within the natural forest concession area, namely plotsnumbered CC 47, K47, and L 47. Each PCP was a rectangular plot measuring 2 ha (200 x 100 m2). The results showed thatthe natural forest stand structure in the study location formed an inverted J letter, where the stands with a diameter class of 60 cmand above had a lower stand volume than other diameter classes. Carbon storage in the stand before felling was 21.07 ton C/ha.The potential for carbon storage decreased when 144 trees were felled, resulting the reduction was 18.49 ton C/ha, causing apotential carbon emission of 67.86 tons CO2-eq. After felling, the potential for carbon storage was decreased or remained by 2.57ton C/ha so that the potential for emission in the post-felling area was 9.43 tons CO2-eq.

Abstract

The formulation of phenolic compounds extracted from biomass not only produces adhesives but can also be used as bioimpregnant. In this study, the synthesis was carried out by copolymerization of resorcinol (R) and formaldehyde (F) into the oilpalm bark extract (S) to produce SRF resin fluid. A complete characterization was carried out using FTIR, Py-GCMS, XRDand DTA. In addition, F emission was also undertaken to ensure its safety for health and the environment. The application ofbio-impregnant was done on samples of the hard (edge) and soft (middle) parts of the oil palm trunk. The results show that the oilpalm bark extract contains polyphenol components that have a strong affinity for resorcinol and formaldehyde in alkaline catalyst(NaOH 40%), so that it can form a copolymer that can be used as an impregnant. The application of the bio-impregnant canimprove the quality of the oil palm trunk in both parts from class V to class III of wood-strength classification with an increase indensity (>100%), hardness (4 times), thickness swelling in both cold and boiling water meets the requirements (<25%), as wellas formaldehyde emission that meets the standard SNI 03-2105-2006.

Abstract

The world's demand for wood is increasing while the amount of solid wood production is decreasing with the depletion of forestsdue to illegal logging and conversion of forest functions as plantation land. To overcome these problems, it is necessary to do theefficiency of wood raw materials so that the use of solid wood can be reduced. One of the efficient ways to use wood raw materials isto utilize optimized wood industrial waste by combining one or more types of wood which are glued together into a single unit,commonly called a laminated board. In this study, we will look at the effect of different types of wood and the weight of the gluespread on the resulting laminated board. Advantages Laminate board can produce a board size that is wide and long as neededbecause the joints are made as long as needed. In the manufacture laminated boards are made with the type of wood, namely jatiputih (Gmelina arborea. Roxb), bajur (Pterospermum javanicum), sengon (Paraserianthes falcataria) and mixtures(jati putih, bajur and sengon) and the glue spread factor is 150 g and 200 g. Then the physical and mechanical properties weretested. The test results showed that the wood type had a significant effect on all physical and mechanical properties except for thethickness shrinkage and MoE tests. The interaction of the lamination glue spread factor and the wood type factor did not significantlyaffect all physical and mechanical properties of mixed wood waste laminated boards. Based on the test results, laminated board isclassified as strong class III which can be used as a lightweight construction material indoors.

Abstract

Rattan has the potential to be developed into composite products with gluing technology into laminated rattan. However, as araw material, rattan has a weakness, namely that it contains chemical components that inhibit the adhesive bond with the chemicalmolecules of rattan. In an effort to overcome this, a technique for making composite rattan was carried out in order to obtain dataon the effect of pretreatment on rattan as a raw material. Rattan as a raw material is first dried by microwave, hydrothermalevaporation and conventional methods in order to reduce the levels of adhesive chemical components contained in rattan. This paperpresents the results of research on the technology of making laminated rattan from the Batang (Calamus zolingerii) large diameter(>20 mm) with mangium tannin adhesive. The results showed that the pre-treatment of rattan as a raw material in the form ofdrying by means of oven, steam, frying, hydrothermal, and microwave, each produced a different effect on the chemical componentscontained and the degree of crystallinity. The best rattan laminate board was obtained from rattan which was pretreated using a 1kW microwave oven (input) with a maximum energy strength of 50%.

Abstract

Carbon has many benefits as an adsorbent, catalyst, drug delivery, energy, and it can produced from various resources, includinglignocellulosic biomass. One of the potential biomass for carbon material is bamboo. The particle size is usually inversely proportionalto the surface area and adsorption level; therefore, studying the particle size of activated carbon is essential. This research aims toproduce carbon and sulfonated carbon from andong bamboo to understand the effect of particle size on the characteristics andadsorption capacity. The method for this research was the pyrolysis of andong bamboo into sulfonated carbon bioproducts usingH2SO4 10N with variations in particle size of 60 and 100 mesh. The proximate analysis of activated carbon based on IndonesianNational Standard (SNI) No.06-3730-1995 includes moisture content, ash content, volatile matter content, and fixed carbon.Sulfonated carbon adsorption analysis was conducted on iodine, methylene blue, ammonia, chloroform, and benzene compounds.The result showed that the proximate parameters of activated carbon produced had met the SNI requirements. The adsorptioncapacity of activated carbon on the adsorption of iodine, methylene blue, ammonia, chloroform, and benzene was 421.71432.50mg/g; 20.3521.90 mg/g; 9.559.98 mmol/g; 10.1615.03%, and 4.63.83%, respectively. Based on andong sulfonatedcarbon data, it can be used as an adsorbent and renewable green catalyst.

Abstract

The development of gamal wood (Gliricidia sepium Jacq.) aims to meet the needs of biomass energy in rural areas. Manystudies on extractives of gamal wood have been carried out, but there is very little information about the effect of extractives on thecalorific value. The effect of extractives on the calorific value can be determined by analyzing extractives compounds contained in thewood. This study aimed to determine the extractives compounds that affect the wood calorific value. The sawdust of gamal bark andwood was extracted by successively maceration by using solvents with different polarities. The free-extractives sawdust was thenmeasured for its calorific value. To ascertain the effect of extractives on the calorific value, the extract of the gamal bark and woodwas added to the oil palm sawdust, then the increase in calorific value was measured. The results showed that the extractives ingamal bark and wood affect the change of calorific value. The removal of extractives by using different solvents caused a differentdecrease in calorific value. The highest decrease in calorific value (4.03%) was obtained by non-polar (n-hexane) soluble extractiveof the gamal bark. The addition of gamal wood extracts to oil palm sawdust also causes an increase in the calorific value.Phytochemical and LC-MS/MS analysis of n-hexane soluble extractives from gamal bark detected groups of terpene compounds,amides alkaloids, flavonoids, coumarins, and benzopyrans. Based on the results of this study, the n-hexane soluble compounds wassuspected to have the most influence on the calorific value.
