The practice of burning and stockpiling to reduce wood waste from the wood processing industry is not in line with the demands of clean production, environmentally friendly and sustainable industries. Pyrolysis technology can be used to produce bioenergy from wood waste. The temperature and the time of the pyrolysis process, the water content of materials, and the content of different yields between types of wood waste affect the bioenergy products produced. This study was aimed at determining the effect of wood waste form and condition on the quality and quantity of liquid smoke, tar, and charcoal. A Completely Randomized Design with two factors of treatments, i.e., waste forms and the drying process, was applied in this research. The results showed that the condition and shape of the material affect the volume of liquid smoke and the weight of the charcoal produced. The condition of the material without drying with high water content and the shape of the chunks produce more liquid smoke with an average yield of 191.14 mL and 186.37 mL, while the charcoal produced is higher in the condition of the material with drying and shaved form at 125.83 g and 115.62 g. The results of the test characteristics of grade 1 and 2 distillation liquid smoke meet the Japanese liquid smoke quality standards with phenol levels in the range of 26.66-35.94 mg GAE/mL sample and acidity levels of 16.91-58.9%. Keywords: Char; liquid smoke; pyrolysis; tar; wood waste.   ABSTRAK Praktik pembakaran dan penimbunan untuk mereduksi limbah kayu dari industri pengolahan kayu tidak selaras dengan tuntutan produksi bersih, ramah lingkungan dan industri berkelanjutan.

Tuna has a high protein and water content, and has solid meat. But tuna is also very easy to damage. The cause of damage fish is a high water content which can cause microorganisms to multiply easily. Fumigation with  liquid smoke is safer and more practical than conventional fumigation, because liquid smoke contains phenol, carbonyl and organic acids which are useful for providing a distinctive taste and as preservatives in fish. The liquid smoke comes from stem of tabah bamboo (Gigantochloa nigrociliata Buse-Kurz). The purpose of this study was to determine the effect of temperature and heating time on the characteristics of processed tuna which soaked in liquid smoke stem of tabah bamboo and to find out the temperature and heating time of the best organoleptic characteristics of processed tuna which soaked in a solution of liquid smoke stem of tabah bamboo. The method used is Factorial Completely Randomized Design with two factors. The first factor is the treatment of heating temperature which consists of three levels, and the second factor is the treatment of heating time which consists of three levels. Each treatment was repeated twice. The best combination of treatments is the heating temperature of 100?C, heating for 4 hours produce pH 5.5, water content 58.06%, ash content 1.69%, protein content 18.29%, hedonic color test 3.94, aroma test hedonic 4.28, hedonic texture test 4.72, hedonic taste test 4.5, texture scoring test 4.83, and the overall acceptance scoring test is 4.39.

Melon is a type of fruit that has a high water content. High water content causes limited fruit storage, therefore it is necessary to preserve it to maintain the freshness of the melon. One method that can maintain the freshness of the fruit is edible coating. The purpose of this study was to determine the characteristics of organolepic melons given starch-based edible coatings from several types of tubers, namely cassava, canna, and lesser yam. This study used factorial Completely Randomized Design (CRD) with two factors. The first factor is the difference in CMC with a concentration of 1% and 1.5%. The second factor is the difference in glycerol with a concentration of 1% and 3%. The results of the study based on the ANOVA test showed that the type of starch treatment and the concentration between treatments did not have a significant effect on the texture, color, and aftertaste of the melon, but significantly affected the taste and aroma of the melon. So it can be concluded that from all edible coating formulations, panelists preferred the PS I formulation (cassava starch) with 1% CMC concentration and 1% glycerol.Keywords: cassava, canna, edible coating, lesser yam, melons

Maize is one of the important staple foods for people in Timor, East Nusa Tenggara Province, Indonesia. Subsistent farmers store the maize for their own consumption until the next harvest season, for seed and feed.  However, high initial water content of the kernel due to improper drying prior storage initiate serious damage and losses during the maize storage.  High water content promotes the growth of fungi and insects, and increase respiration rate, resulting in rapid deterioration of maize. The purpose of this study was to determine the initial moisture content that might minimize damage and losses of maize in the farmers’ storage, and to study the effects of some plant materials that are used to smoke corns before storage. The experiment was initiated by sun-drying the harvested corncobs for 0, 2, 4, 6, 8, and 10 days (6 hours a day). This experiment was designed using Completely Randomized Design with 6 treatments and 3 replications. Dried corncobs were stored in the farmer’s storage for 4 months. The effects of maize kernels’ initial water content on the development of water content in kernels; the percentage of damaged kernels; and the species of pathogen and insects were investigated during storage with 2-week intervals.  The results demonstrated that drying the corncobs prior storage for 10 days, resulting in 12.96% of water content, significantly decreased the percentage of seed damage to 6.5%, as compared to without drying process which resulted  in 63%.  Aspergillus flavus, Fusarium sp., and Penicillium sp were found to be the main pathogen during storage.  There are no insect pests found during the storage.

The high water content in dragon fruit causes the fruit to be easily damaged, therefore it needs to be processed to reduce the amount of loss, including making it into jam. In addition, processing dragon fruit into various processed products also aims to overcome the problem of excess production when the harvest season arrives. The aim of this research was to obtain the ratio of dragon-sugar fruit which gave the best influence on the physical, chemical and organoleptic characteristics of jam. The study used a completely randomized design (CRD) for the analysis of physical parameters of jam (softness) and chemical jam (water content, total dissolved solids, anthocyanin and vitamin C levels). Randomized Group Design (RBD) for analysis of organoleptic test parameters (color, texture, taste and preference). As a treatment, it is the ratio of dragon-sugar, which consists of five levels of treatment, namely P1 = dragon fruit 450 g: granulated sugar 550 g, P2 = dragon fruit 500 g: granulated sugar 500 g, P3 = dragon fruit 550 g: sugar 450 g, P4 = dragon fruit 600 g: granulated sugar 400 g, P5 = dragon fruit 650 g: granulated sugar 350 g. Each treatment was repeated 3 times so that there were 15 experimental units. The data obtained were analyzed using F test 0.01 and 0.05. If the treatment has a significant or very real effect, then proceed with the BNJ test at tararf 0.01 and 0.05. The results showed that treatment P4 (600: 400 b / b dragon-sugar ratio) gave the best influence on the physical, chemical and organoleptic characteristics of dragon fruit jam. This treatment can reduce the use of sugar by 15 percent from the standard use of sugar in making jam.

The species Eugenia stictopetala, known as “cambucá” or dog-tongue, is found in areas of Cerrado and produces fruits in the form of drupe, black when mature and much consumed by the fauna. Despite its potential for use, there is no information about its germination processes and for this reason, the objective of this work was to evaluate its germination and seedling formation at different temperatures, besides its germination after initial storage. Newly collected seeds from the Cerrado area were evaluated at six temperatures (20, 25, 30, 35, 20-30 and 25-35 °C) and after 35 days of storage in different environmental conditions in a completely randomized design. The results indicated that the seeds have a high water content and the temperature of 30 °C being the most suitable for germination and seedling formation. After storage, loss of water content occurs, leading to a reduction in germination rates, indicating a characteristic of recalcitrant seeds.
