Abstract

Palado seeds (Aglaia sp.) are originally part of wild forest plants commonly used as a snack by boiling and roasting. Theutilization of these seeds into flour increases its value and extends the storage time as an alternative food ingredient. Therefore, thisstudy aimed to analyse the macronutrient content of palado flour by proximate anlysisi. Parameter analysed includes moisture ash,fat, protein, carbohydrate, and energy contents the palado flour. Analysis of moisture content was determined by drying method; ashcontent was determined by ashing in a furnace; fat content was determined by soxhlet method, protein was determined by the MicroKjeldahl method, carbohydrate content was determined by weight talce, and energy content was determined by the sum of the weightof crude protein, carbohydrates, and fat. The results showed that the palado flour consisted of 66.72% carbohydrate, 12.37% fat,3.61% ash, and 414kcal energy. This research indicates that palado flour could be an alternative flour, both as the main foodmaterial and as a fortification palado seeds, alternative food, nutrition content, flour, bread and noodles.

Abstract

Jati Utama Nusantara (JUN) is one type of growing regime of fast grown teak (Tectona grandis Linn. F) derivedfrom Jati Plus Perhutani (JPP). JUN trees have fewer branches and a more cylindrical-shaped trunk, as well asexhibit rapid growth compared to the teak cultivated from seed (conventional); accordingly, they can beharvested in a shorter time. Despite its fast growth, some studies showed that the wood had not met the SNI01-0608 standard as raw material for furniture. The research aimed to improve several physical and mechanicalproperties of young JUN wood through thermal compression treatment. The test sample for 5-year-old JUNwood was prepared with a size of 2.5 cm (thickness/radial) by 10 cm (width/tangential) by 30 cm(length/longitudinal), then compressed using a 25 kg/cm2-pressure for 40 minutes in three temperaturetreatments of 170°C, 180°C, and 190°C. Testing of wood mechanical and physical properties referred to ASTMD143. The wood crystallinity was observed using an X-Ray Diffractometer (XRD), and the wood surface wasobserved visually. Wood cell structure as supporting data was observed using a stereo-capable microscope(Zeiss). The results revealed that the thermal compression could improve the physical and mechanicalproperties of the densified JUN samples compared to the nonthermally compressed samples. Based on datasimulation, the wood samples' best physical and mechanical properties occurred at approximately 185°C's heatpress.

Abstract

Indonesia is one of the exporting countries for wood crafts to 193 countries, but in the process, it often suffers losses due toproduct returns by the buyer due to cracked defects when the goods arrive at the ordering country. One of the efforts to improve thequality of wood crafts is to dry the wood according to the destination country so that the dimensions and humidity are relativelystable. The industrial-scale wood drying process requires a high investment, so developing a small-scale dryer for artisans is necessary.This study aims to design and test the performance of a simple wood dryer with a capacity of 1.5 m³ at an affordable cost, easy tooperate and use by the public. The test samples used were stems and branches of teak (Tectona grandis L.f.). The heater used isa combination of solar heat and electricity, namely the heat of the sun is maintained and flowed into the wood drying chamberthrough a fan that sucks hot air from the combustion chamber into the drying chamber. Hot air is circulated to the inlet againcontinuously to be redistributed to the drying chamber. The test results show that the daily average temperature of solar heat receivedby the drying chamber is between 40−50°C, while the temperature for drying teak wood is between 45−70°C. From the evaluationthat has been done, the heating plate is less effective in heating the space, so it is necessary to replace it with a modification of theinstallation of the heating element on battery powered devices.

Abstract

Catalytic cracking is a conversion process by cutting the carbon chains of oil molecules into simple hydrocarbons. The process ofbreaking the hydrocarbon chain could be conducted by chemical means using a catalyst and hydrogen gas. The types of catalystscommonly used in the chemical industry are metals such as nickel (Ni), zinc (Zn), and cadmium (Cd). The metal can be used asa catalyst directly, but during the catalytic cracking process, the catalyst will thicken than it is imposible to re-use the catalyst.Therefore, the metal catalyst must be impregnated into a carrier material such as zeolite. The research is aiming for analyzing thecharacteristics of active natural zeolite catalyst with nickel-metal impregnation (ZAA/Ni), which consisted of surface area analysis,XRD, FTIR, and morphological analysis best catalyst. The zeolite used in this research is originated from Bayah Banten, whichhas been activated. The function of the catalyst can be improved by the presence of a carrier, namely nickel metal. The role of thecarrier is as a place for the active nucleus to spread, which can increase the effectiveness of the catalyst so that the catalyst can beused repeatedly. Results show the highest Si/Al ratio is 6.66, an intermediate catalyst with a Si/Al ratio = 2−10. The widestsurface area of the catalyst is at ZAA/Ni 3% of 974.44 m2/g; the crystallinity value the largest was 70.09%. Zeolite fromBayah Banten, impregnated with nickel-metal, can be used as a catalyst for upgrading bio-oil with a concentration of 3% ZAA/Niand 2% AA/Ni.

Abstract

Plants of Garcinia genera (Fam: Guttiferae) that grows in Indonesia's tropical forests are potential of triterpenoidcompounds contents. Garcinia cymosa has been reported as the main source of triterpenoid compounds whichprovided useful biological activity such as anti-inflammatory, antibacterial, antifungal, antioxidant, cytotoxic, andanti-HIV. Currently, data and information of triterpenoid compounds in the G. cymosa is relatively low. Thispaper studies triterpenoid compound of G. cymosa. This compound was obtained from macerated G. cymosa stembark using n-hexane solvent. G. cymosa bark was macerated using n-hexsana solution, which was them separatedand purified by chromatography method, to produce pure isolate in the form of white needle crystals (10.8 mg). Thechemical structure was then determmined by using spectroscopy methods of IR, 1D-NMR, 2D-NMR, and massspectroscopy compared with published structure. Result show friedelin compound was succesfully isolated from extractedn-heksana of G. cymosa bark.

Abstract

Currently, timber harvesting activities in natural forests are more efficient with reduced impact logging (RIL). More efficientwood harvesting will reduce waste, which increases the standardization of exploitation factors (FE). Ironically, until now, theFE standard set by the Ministry of Environment and Forestry is still based on conventional wood harvesting methods, which is0.7. The sub-region of Central Kalimantan Province has a major role in contributing to production of natural forest logs, bothregionally on the island of Kalimantan by 61.5% and nationally by 29.7%. Still, the amount of wood harvesting waste is notknown with the standardized exploitation factor. This study aimed to obtain a standard number of exploitation factors fortimber harvesting activities in natural production forests in the sub-regional province of Central Kalimantan. The research wasconducted by initially selecting purposively logging companies with Sustainable Production Forest Management (PHPL)mandatory and voluntary certificates. The study was conducted in five of Forest Utilization Business License (PBPH) withPHPL mandatory certified and voluntary certificates. The results showed that the potential for logging waste due to stem divisionin felling site is an average of 0.919 m3/tree and the amount of logging waste due to testing and measurement at the TPn is onaverage 0.093 m3/tree. The FE score ranged from 0.80-0.85 with an average of 0.82. Factors that influenced the FE coefficientinclude the skill of the logger and management policy of PBPH and the diameter of the tree felled.
