Abstract

Formulasi Baru Pembuatan Kertas Berbasis Serat Aren sebagai Potensi Material Grafika di Masa Depan telah dilakukan. Tahap awal pembuatan kertas dilakukan dengan membuat pulp dilakukan dengan cara metode kimia sulfat dengan mencampurkan larutan Natrium Hidroksida dan Sodium Sulfida masing-masing sebanyak 262,98 ml dan 116,67 ml dimasak menggunakan mesin rotary digester selama 2+2 jam dengan suhu 170°C. Perbandingan sampel dan larutan pemasak adalah 1:4. Selanjutnya pulp dicuci dan dikeringkan dengan mesin pengering. Sebelum dicetak pulp terlebih dahulu digiling hingga mencapai derajat kehalusan ideal suatu pulp yaitu 250-500 ml CSF. Kemudian pulp dicetak sehingga didapatkan lembaran kertas. Dari pengukuran morfologi menggunakan Scanning Electron Microscope dengan perbesaran 500x dan tegangan 10kV didapatkan ukuran serat kertas berbasis batang aren sebesar 20 mikron.

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 availability of organic ameliorants is very important to induce seedling growth. This study examines the effect of various organic ameliorant addition into the growth of kemenyan seedlings (Styrax benzoin Dyrand), trembesi (Samanea saman Jack. (Merril.) ) and ki bawang (Melia excelsa Jack). The addition of organic ameliorants were grouped into 11 different treatments: (p) soil (control); (q) charcoal organic fertilizer (POA) 10%; (r) POA 10%+ charcoal sawdust (ASG) 5%; (s) POA 10% +ASG 10%; (t) organic fertilizer tablet of charcoal and mycorrhiza (POAM); (u) organic fertilizer tablet of mycorrhiza (POM); (v) POM + ASG 5%; (w) wood vinegar (CK) 1%; (x) CK 1% + ASG 5%; (y) CK 2%; (z) CK 2% +ASG 5%. The Results showed that treatment r, the use of 10% charcoal organic fertilizers (POA) and5% charcoal sawdust (ASG) affected most significantly to the height increments. The analysis of variance showed that the various treatment of ameliorant addition affected significantly to height increments but did not have significant effect to the diameter increments.

Abstract

Porang (Amorphophallus muelleri Blume) is an alternative food sources from forest. Porang grows under forest canopy and potentially developed to improve food security. Naturally harvested porang contains high oxalate and less glucomannan. This paper observes possible quality improvement of porang flour in term of whiteness and glucomannan content. Porang collected from Nganjuk, East Java was quality tested and mixed with natrium bisulfite then rinse in ethanol repetitively. Results showed that the addition of sodium bisulfite improved the whiteness of porang flour for about 6.59%. Ethanol dehydration proces was able to improve glucomannan content from 12.86% to 38.11%. Fe and Ca content of mixed porang flour showed no significant difference. Porang flour from Nganjuk contained of 1,6-AnhydroBeta-D-Glucopyranose; 1,2,3,4-Cyclopentanetetrol,(1.alpha., 2.beta., 3.beta., 4.alpha.); cyclopropyl carbinol; aceticacid(CAS)ethylicacid; and hexadecanoic acid.

Abstract

Biodiesel is a diesel fuel made from vegetable oils extracted from various forest plants. This paper studies the characteristics of biodiesel made from Bintaro's seed (Cerbera manghas L.) by modified process. The modification process includes pretreatment and degumming processes. In the pretreatment process, modification includes raw material's treatment such as steaming, washing, drying and compressing. Degumming modification process includes addition of phosphoric acid catalyst, then bentonite; esterification by methanol acid catalyst and followed by addition of zeolite; the transesterification process by methanol bases catalyst. Results show that physico-chemical properties of biodiesel made from Bintaro's seeds including acid value, density, iod number, viscosity and ester-alkyl content met to Indonesian National Standard (SNI) on Biodiesel.

Abstract

Six wood species from West Java which are ki hiur (Castanopsis acuminatissima A.DC.), tunggeureuk (Castanopsis tunggurut), huru pedes (Cinnamomum iners Reinw.Ex Bl.), huru koja (Litsea angulata Bl.), ki kanteh (Ficus nervosa Heyne) and kelapa ciung (Horsfieldia glabra Warb) have been distillated by dry distillation at temperature 450°C-500°C for five hours in the retort distillation. Distillates from the dry distillation in form of charcoal, tar and liquid are calculated. The results exhibited charcoal quality of six woods meet the standards of Indonesia for charcoal and charcoal briquettes with calorific values ranging from 6743-6795 cal/g, fixed carbon ranging from 79.42 % - 82.37 %. Charcoal yield ranging from 27.43 % -33.55 % . Pearson correlation analysis on the lignin content and woodgravity to charcoal calorific value indicates that the lignin content has a significant correlation to the calorific value of charcoal.

Abstract

Porang (Amorphophallus muelleri Blume) as a non-timber forest product (NTFP) has many advantagescompared to other food crops. In order to the cultivation aspect and excellence of the flour, it made this commodity afood sources in the future. Today, technical post-harvest processing become the current problems especially in gettingoptimum glucomannan. With increasing levels of glucomannan, it made the utilization and marketing of flour will bewider. This study aims to optimize of purification techniques of glucomannan. The research method is through soakingtechniques with ethanol (30%, 40% and 50%) and sodium bisulfite (2%, 3% and 4%). The results showed that theleaching technique ethanol made a significant effect on the increase in glucomannan levels. The immersion technique with50% ethanol and 2% sodium bisulfite can increase glucomannan from 32.65% to 83.96%. The process of soakingwith ethanol not affects the content of ferrum (Fe) and calcium (Ca) in porang flour.

Abstract

There are about 4,000 timber producing trees grow naturally in Indonesia, which comprise of commercially and lesser known wood species. Wood chemical component analysis is one indicator for timber utilization. This paper studies the chemical components of five lesser-known wood species originated from West Java namely ki bugang (Arthophyllum diversifolium Bl.), sempur lilin (Dillenia obovata Hoogl.), cangcaratan (Lithocarpus sundaicus Bl.), ki pasang (Prunus javanica Miq ), and ki langir (Othophora spectabilis Bl). The analysis was conducted according to the testing standard of Norman Jenkin, Indonesian National Standard (SNI) and TAPPI. Results show that Ki bugang has the highest content of both of cellulose and pentosan about 52.57% and 21,37%, respectively. Cangcaratan wood has the highest lignin content about 31.84 %. Ki langir has the highest solubility in cold water, alcohol benzene and NaOH about 3.34%, 2.75%, and 22.17%, respectively. In addition, sempur lilin has the highest solubility in hot water about 8.56%. The highest ash content is 3.60% belongs to Ki langir and the highest silica content is 1.92% belongs to sempur lilin. Based on the chemical content, cangcaratan wood is recomended for pulp and energy purposes and ki bugang wood is recommended for bio-ethanol.
