Abstract

Study on thermal processes using renewable energy sources for drying and cooling purposes hasc been selected due to their importance in extending shelf life of agro and marine products which arc susceptible to high temperature and humidly under the tropical climatic conditions. The unavailability of these facilities had resulted in significant amount post harvest which sometime may reached up to 30% of harvest. This research was aimed to determine the proper design and construction of renewable energy conversion, namclyt, solar, wind and biomass to generate thermal energy for drying and cooling of agricultural and marine produccts. Both processes could also be used as the main component of a Small Processing Unit (SPU), an early form of SME and cooperative at village level. This paper will discuss Part I of the study which will be focused on the application of renewable energy sources for the drying of agricultural products. The following conclusions had been achieved. a). Study on simultaneous momentum, energy and mass transfer in thin layer drying process of rough rice have provided information on air temperature, velocity and RH distribution above the grain. b). A novel ventury type CIIE solar dryer with solar PV power supply and PCM energy storage, has been successfully designed and constructed. Test results have shown that the dryer could he used to dry 75-95kg of fish within 36 to 40 hrs. wirh apparent PCM energy storage of 6.9M.J (6 hrs. drying time). c). Mathematical modelling and simulation of a biomass stove heated recirculation dryer indicated that drying of rough rice could be completed within 3-6hrs (1.8-3.7T.hrs-1 recirculation rate with one hour tempering time) if 2 HP blower is used.   Keywords : energy storage, momentum and mass transfer, recirculation dryer, renewable energy conversion, simultaneous energy

Abstract

This filed research was conducted from Apr 2006 to .Juni 2007 at natural tropical rainforest of the Lore Lindu National Park, Central Sulawesi. The objectives were to study the effect of rainfall properties and vegetation characters on interception losses through mathematical model approach, to estimate the rainfall interception losses and to determine the dominant factors influencing them. Observation of vegetation characters in the study area indicated that the vertical and horizontal structure were in good conditions with high leaf area index (LAI 4.8-6.43 m2.m-2 ), ground cover (68.5-92.59%) and wide canopy at average 5.59 (12.05-9.83 m2 Total rainfall (P) on the first measuring phase (Apr 2006-March 2007) was 1502,6mm for 172 events. Dominant rainfall depth was 0.5-5mm for 78 events with cumulative rainfall at 182.2mm or 12.3%, of P. Dominant rainfall intensity was 1--10 mm per hour for 121 events with cumulative rainfall 140.2 mm or 9.3 % of P. The mathematical relationship between rainfall properties and vegetation characters with throughfall, stemflow and interception loss show that rainfall depth and LAI are two factors that strongly influences as expressed: interception loss: Ic= 0. 786+0.343* P+0.051 *LA I (R2=73,77) Application of this equation and Gash model to the second measurement phase (Apr 2007-Juni 2007) gave good agreement on interception estimate and sensitivity, and considering data requirement and calculation procedure this equation is applicable for interception estimation. The critical point of this result is the rainfall properties on Lore Lindu National Park that is very important to forest management, especially in controlling of flooding. Keywords : rainfall interception, tropical rain forest, vegetation characters

Abstract

Tracking timber on teak and teak wood products can be conducted using different methods, such as DNA finger printing, chemical composition of the wood, Near Infra Red spectra (NIR) and stable isotopes. Samples were collected from wood material and leaves in Java (9 Forest Management Units district) of Perhutani to determine: i) pattern of genetic variation within and among populations, ii) to determine the protocol for DNA extraction from wood, and iii) to study the feasibility of DNA marker for timber tracking in the field. Results show that: i) genetic variation of cpDNA (PCR-RFLP) is low, while RAPD variation is moderate, ii) there are differences in chemical composition of wood among the Forest Management Units (FMUs) of Perhutani, iii) variation of isotopic carbon and oxygen in Central and East Java were higher than from of West Java, iv) absorbtion intensity of NIR in West Java was higher than for Central and East Java, and iv) testing of DNA marker showed that genetic structure in the forest site is not significantly different from that in log yards, indicating that the timber flow is still according to the procedure. RAPD marker also is able to determine the origin of illegal timber and wood in industry without clear identity. Keywords: genetik marker, teak, timber tracking

Abstract

 The curing process of vanilla beans from dried vanilla to vanilla extract would give added value to vanilla products. Aroma and taste in vanilla extract depend on variety of plants, cultivation methods, and curing process. Indonesian vanilla extract tend to give woody and phenolic aroma because it was harvested too early and it did not cure perfectly. This study was to identify the physicochemical and aroma characteristics of vanilla extracts from importer, exporter, and vanilla extracts from the newest experiment from our laboratory. There  were seven samples, three from importers (Tahiti grade I, Tahiti grade II, Virginia Dare), two from Indonesian Vanilla exporters (Djasula Wangi, Cobra), and two from our laboratory (G11, 57). The  physicochemical characteristics which were analyzed were vanillin content, ash, soluble ash, alkalinity of soluble ash, alkalinity of  total ash, total acidity, and lead number, all compared with the Food and Drugs Administration (FDA) standard. Sensory analysis used aroma description test consist of qualitative descriptive test (in-depth interview and focus group methods) and quantitative descriptive analysis. The result showed that the laboratorys sample from modified curing process (G11) followed the FDA standard in physicochemical characters, but the aroma description was not as strong as the aroma of vanilla extract from exporters, namely Cobra with creamy, sweet, and vanilla aroma; and vanilla extract from importer, namely Virginia with smoky and spicy aroma.   Keywords: vanilla extracts, aroma

Abstract

The research done based on the fact that the log from natural forest could not fullfil the need of domestic forest industry. Annual available cut from natural forest in the year 2007 was only 9.1 million m3 while forest industry domestic country in the year 2005 reached 44.5 million m3.  Raw material crisis was the most problem facing by domestic forest industry and the solution could be come soon as posible. The establishment of social plantation forest is one of the government program to solved the lack of forest industry raw materials. The species for social plantation forest are available more than enough. Previous research done in the year 2009 shown taht most of HTR log was small diameter, short sortimen, heart wood presentation of juvenile wood was very high. The result of research shown that the basic characteristics of three species of HTR namely: Jabon, sengon and pulai have a good colour (bright), moderate texture, fibre is slim to interlocked, have no decoratif form, bulk density low. The characteristic of 6 species HTR was: variation in colour, good texture until moderate, fibre direct until interlocked, the wood have beautiful decoration, moderate bulk density. Basic of characteristic of wood is very important in affacting the quality of the products. An effort to increase the quality of HTR wood should be done so that the use of HTR product becaming important to suggest the developing of creative industry.  Keywords: Basic characteristic of wood, HTR, decorative, creative industry.

Abstract

The agricultural sector, particularly the rice farming system (SUT) is very vulnerable to climate variability and change. SUT that rely heavily on water will be easily affected by climate variability and change when the water supply deficit of needs that should be. SUT is still dominant in the food supply in Indonesia, so the shock of farming due to extreme climate events will have a major impact on food security. Many findings indicate that the frequency and intensity of extreme climate events will increase as a result of global warming. Extreme climate events dominant occur in center of rice production in West Java like Indramayu is drought. Approximately 80°/o of the causes of the rice harvest failed in the district of Indramayu is the incidence of droughts. Farmers as the main actors receive large impacts due to drought is expected to be increasingly difficult to develop the farm. It is therefore necessary to have protection program for farmers from the impact of climate events such climate extrim. One option is starting a lot of feasibility is Climate Index Insurance. This study aimed to assess thefeasibility of the implementation of the climate index insurance system in Indramayu. Analysis step is performedinclude (i) preparation of endemic drought maps are required as the basis in determining the priority areas ofclimate risk management and (ii) the determination of climate index value (threshold value) to be used as an index into the determination of the value of insurance claims. This study found that climate indices that can be used for the three villages at high risk of drought is high rainfall during the dry season. Index value for the three villages is 168 mm, 248 mm and 472 mm for Cikedung, lelea and Terisi. Potential applications of Climate Index Insurance for rice SUT in Indramayu is high because about 90°/o of the people are rice farmers. Besides benefit of rice farming is also quite large with B/C from 1.4 to 1.8 during the wet season and 1.2 to 1.7 on the dry season, so the expected ability to pay insurance premiums high enough.Keywords: Climate Index Insurance, drought, rice farming system.
