<![CDATA[Indonesia one of the plants that leaves and seeds grow has many useful benefits for human life, namely candlenut. The post-harvest handling of candlenut at the farm level it is generally still done traditionally where candlenut is drying on the floor or by direct exposure to solar radiation. They need approximately 7-9 days to get the appropriate drying results. Candlenut drying is influenced by the intensity of solar radiation on temperature and drying time according to the required hazelnut content. the dry hazelnut can use solar radiation power that is solar dryer. Absorbent plate is one component that is very important because it functions to absorb the intensity of solar radiation and convert it into heat energy and move it to the workpiece (candlenut) above it. In this study, testing was done on variations of the absorbent plates of zinc, aluminum and iron as well as variations in the thickness of the absorbent plates. Data collection starts at 09:00 until 15:00 WITA in sunny weather conditions. The results showed that the aluminum absorbent plate with a thickness of 0.04 mm was more effective and efficient in drying the candlenut to increase the productivity of the candlenut. The highest absorbent plate temperature and drying time were found on the aluminum absorbent plate with a thickness of 0.4 mm that is 72.36 oC and a drying time of 6 hours and meets the standard of moisture content of candlenut solution, which is 5.3%.]]>

<![CDATA[Some time ago in the region of West Nusa Tenggara (NTB) experienced earthquake shocks which shocked the community so that many buildings were destroyed and razed to the ground. While the current use of plastic waste is a concern of the community and government, especially in the NTB region. So this background is the basis of research to make earthquake-resistant lightweight bricks by utilizing PET plastic waste to replace coarse aggregate as a mixture and use sisal fiber as a reinforcement to strengthen the strength of lightweight bricks. The purpose of this research is to find out how to make light brick type CLC (Cellular Lightweight Concrete) by utilizing PET plastic waste and sisal fiber, to determine the effect of the addition of PET plastic and sisal fiber to the mechanical properties of light bricks, and to determine the optimum composition of the addition of plastic PET and sisal fiber in the manufacture of lightweight brick CLC. The use of PET plastic and sisal fiber produces brick with an average density of 1,830,419 kg / m3 for 1: 1 variation samples, 1,880 kg / m3 for 4: 1 variation samples, and 1,887,654 kg / m3 for 1: variation samples 4. Maximum compressive strength is achieved in 1: 4 variation samples ie samples with the addition of sisal fiber 4 times more than PET plastic.

<![CDATA[Consumption of fast food continuously can be detrimental to human health. An effective solution is to make innovative food that is able to meet the adequacy of nutrition, one of which is foodbar. The raw materials used in the manufacture of foodbar come from local commodities which are flourished, including sweet potatoes, green beans and Moringa and added porang to unite the three ingredients. Yellow sweet potato flour contains 77.7% carbohydrates with high digestibility (98%), while Moringa leaf flour contains 27.1 grams / 100 grams protein. Mung bean flour is used as a flavoring agent, while porang flour which is rich in glucomannan acts as a binder agent to produce foodbar products that are not easily destroyed. The treatment in this study used two factors, namely the composition of the composite flour and the composition of the addition of porang. Observations made include physical properties including water content, volume expansion, kamba density and texture of the foodbar. The best treatment on the foodbar was the combination treatment of 100 grams of yellow sweet potato flour (40 grams) green bean flour (60 grams) moringa leaf flour and (4%) porang (P3T1).]]>

<![CDATA[Every choice of meaning is ideologically motivated. Ideology is most effective when the work is not visible. Interpreting ideology in the text can be seen from the choice of vocabulary and grammatical construction. To analyze it we need to interpret not only the text but also the relationship between the text, and its social conditions. According to Fairclough, they can be grouped into three stages, namely description, interpretation and explanation. Stages of description relate to the formal nature of texts, interpretations relating to the relationship between texts and their interactions, explanations relating to the relationship between interpretations and social context.To analyze data using referential methods, substitution methods and abductive inference methods. The referential method is to analyze the system of assessment and discourse intertextuality of texts. To carry out an analysis of a valid grading system a substitution method is needed. Then the abductive inference method is needed to analyze the relationship between texts.From the results of data analysis, it can be concluded that each media has its own way of expressing its ideology. Ideology has closed the relationship with the target market that is the reader. Rungan Samawa is an online place for Sumbawa people, the news is very clear and concise, with a sharp choice of vocabulary, all related to the genre of news they have. The Case of the Local Indigenous Community Coalition Sued Amnt is a form of concern for the Samawa people who are all over the world.]]>

<![CDATA[A study was conducted on the differences in strain and female age on the number of descendants of fruit flies (Drospohila melanogaster Meigen) to determine the effect of strain and female age on the number of D. melanogaster offspring in normal, taxi and sepia strains. Five D. melanogaster ? normal crossed with 5 D. D. melanogaster ? normal, 5 D. melanogaster ? taxi crossed with 5 D. D. melanogaster ? taxi, 5 D. D. melanogaster ? sepia crossed with 5 D. D. melanogaster ? sepia. Age of the crossed female is 8-10 hours, 12-14 hours, 16-18 hours, 20-22 hours, and 24-26 hours after hatching from the pupa. Each group of crosses was repeated five times. D. melanogaster crossing was carried out at 25oC. Data were analyzed with factorial anava and then tested further with LSD (Least Significant Difference) of 5% significance level. Based on the results of the study note that there is an influence of strain and female age on the number of offspring. It is also known that normal strains produce the highest number of offspring, whereas taxi strains produce the fewest offspring. Age of females 20-22 hours produces the most number of offspring and is not significantly different from females 24-26 hours, while ages 8-10 hours produce the fewest number of offspring and are not significantly different from ages 12-14 hours.]]>

<![CDATA[Single leaf spring is one of the suspension systems on vehicles that function as vibration dampers which usually use steel. One type of steel that is often used in making single leaf springs is 55Si7 steel. However, at this time composite materials began to be used as an alternative material to replace steel. One of the composite materials used as a substitute for steel is E-glass epoxy. This study aims to determine differences in the characteristics of steel leaf springs and e-glass epoxy composites. In addition, the effect of orientation of the fiber direction to deformation, stress, and safety factors on leaf springs was also carried out in this study. The analytical method used is finite element. The results showed that the composite leaf springs had lower stress than steel leaf springs. E-glass epoxy composite leaf springs variation D (fiber orientation 45º / -45º) showed the lowest stress and highest safety factor with values ??of 596 MPa and 1.4 respectively.]]>

<![CDATA[The purpose of this research is to reflect back 200 years of the eruption of Tambora on the island of Sumbawa, West Nusa Tenggara through travel with a photographic study approach, specifically travel photography. Since its inception, photography has played a constitutive role in shaping a travel record, this is also comparable to the importance of that role as a depiction of social identity (Osborne, 2000). In addition, travel photography is also a way to see experiences through visual authentication (Hilman Wendy, 2007). Mount Tambora erupted in April 1815, impacting global climate change and natural disasters which claimed 84,000 lives on the island of Sumbawa, and buried the Tambora kingdom and Concentrated .. Based on the results of research, researchers see the occurrence of reconstruction in the history of the eruption of Tambora which is not only seen as a mountain, but also as an identity in the social structure of society in the form of photography. A photographer has the authority to create a reality from pre-travel to post-travel.]]>
