Seaweed is one of the superior commodities of aquaculture in Kertasari Village, Taliwang District, Sumbawa Barat, Nusa Tenggara Barat, with an area of ??1,550 ha in 2013 with a production of 9,850 tons. Post-harvest handling and processing of seaweed is still conducted traditionally, efficiency and the quality of seaweed produced is low. Long enough drying can affect the growth of microorganisms in seaweed, causing the growth of mold and fungus. The explanation of the problem above makes the writer try to find a solution of the problems faced by seaweed farmers in Kertasari Village, with a maker of seaweed dryers based on Solar Dryer. The solar dryer uses a corrugated plate solar collector with a slope angle of 45o and a zinc plate material with a thickness of 0.4 mm with a conductivity value (k) of 116 W / moC. In addition it uses a clear glass cover with a thickness of 3 mm with a slope of 15o. This tool uses a framework in the form of aluminum, with the tilt angle used can produce a Tout of 70.64 oC and Tin of 56.11 oC.

Brang Biji River is one of the rivers prone to flooding. Flooding occurs can result in a collapse in the construction of the retaining walls of the soil causing substantial harm to the surrounding community. It takes an alternative in maintaining the stability of slopes to reduce the avalanche in the Brang Biji River. Alternative wall retaining walls namely pairs of stone times and Sheet Pile, while comparative analysis to determine the type of effective construction used in the Brang Biji river using manual calculation method and software Plaxis 8.6. Data collection through field surveys, to get soil type data, geometrics slopes, and soil layer. To get the stability of slope in existing condition, in case of a cladding with SF ? 1 criteria using method of reverse analysis or approach based on trial and error literature. Results obtained from the reverse analysis are used for the analysis of the compoon on the slope of the Brang Biji River, either by manual calculation or Software Plaxis 8.6 In determining the value of SF. After analysis of the stability of the slope, obtained the result that by using a stone time retaining wall with a height of 5.5 m, the bottom width of 3.85 m, the upper width of 0.6 m with a depth of 1.5 m from the ground surface and the height of the river water face around 7.8 m , both against the bolsters with SF = 3.4, against sliding with SF = 2.17 and the power of land with SF = 3 manually while using the Plaxis Software with the addition of the working floor with a thickness of 10 cm and piling with a diameter of 40 cm with a distance of 25 cm obtained SF = 1.26. Whereas by using Sheet Pile use manual calculation obtained depth (D) Sheet Pile about 2.43 m with a large stability backup (SF) = 1.5 D and the length of Sheet Pile as a whole about 8.43 m from ground level, while using Plaxis obtained value SF = 1,167.

Nusantara Sakti Sumbawa (NSS) is a Honda agent company which sells motorcycles. The company encounters difficulty in determining the monthly sales target of their products. Therefore, the study aims to investigate the appropriate methodology to estimate the sales target for the next five months in NSS by involving 13 different brands of Honda. To achieve the goal, the researcher conducted several stages in forecasting methodology, including collecting the previous sales data of the company, plotting the collected data, and identifying the proper methods of forecasting to analyse the data. Based on the plotting data process, the researcher found that the Time Series methodology, consisting of Single Moving Average and Single Exponential Smoothing was the most suitable method to analyse the data. The results of the study showed that the prediction for the future sales target of the 13 different brands of Honda in the next five months in NSS was 182 units in total (Beat Sporty CW: 35 units, Beat street: 19 units, Vario 110: 14 units, Vario 125: 17 units, Vario 150: 15 units, Scoopy: 38 units, Revo: 1 unit, Blade: 1 unit, Supra X 125: 12 units, Supra GTR 150: 9 units, Sonic: 16 units, and CBR150R: 5 units). The study also revealed that the Single moving average was a proper method to predict the future sales target for the three brands of Honda, namely Vario 110, Revo, and Blade. While the other 10 brands, including Beat Sporty CW, Beat street, Vario 125, Vario 150, Scoopy, Supra X 125, GTR 150, Sonic, and CBR150R were appropriately predicted using the Single Exponential Smoothing method.

To fully utilize the intermittent renewable energy resources, energy storage applications such as lithium-ion batteries (LIBs) become very critical. Among LIBs components, cathode part is very important. LiFePO4 material is among the cathode material which has gained significant attention owing to its environmentally friendly and low-cost features compared to Co- or Ni-based cathodes. In this study, we present a theoretical investigation of LiFePO4 material using density functional theory calculations. We optimized LiFePO4 as well as FePO4 structures. Li ion intercalation potential into the structure was also calculated. In addition, the electronic structure of the material was also studied. The present study may provide an insight for further investigation of cathode materials for LIB applications.

The amount of plastic used in this era has many impacts, one of which is plastic waste, but this shows that plastic has many benefits and advantages so that it is used in almost all things in everyday life. Reuse (recycling) of plastic will be very helpful in dealing with plastic waste problems. One alternative to plastic recycling is the use of plastic waste as a material for making lightweight bricks. Problems that are often encountered in the use of conventional brick in this era are the density (density) and compressive strength, where the expected results are with a low density (density), can produce high compressive strength. Presentation of the above problems makes the writer interested in researching the use of plastic waste to be used as raw material for making lightweight bricks. In this study used 4 variations of plastic types, namely PP, LDPE, and HDPE, making plastic specimens mixed with pumice waste because it has porous and lightweight characteristics, with a ratio of 50:50 from volume. With each variation consists of 2 (two) beam-shaped samples to be tested for density (?) and compressive strength (P). A total of 6 samples. The results showed that LDPE plastic material mixed with pumice has the best density and compressive strength compared to other types of mixtures with the value of ? = 0.76g / cm2, and P = 123.15kg / cm2 or 12.08MPa.

This sound absorption test was conducted by finding the value of Sound Transmission Class (STC) using the impedance tube testing method that refers to the ASTM E413 standard. This study aims to determine the effect of the percentage of composite pumice - PET plastic on sound absorption. As for the variation of the volume fraction of pumice: PET plastic that is (40:60, 50:50, 60:40)% based on the volume ratio. In this study it can be seen that the highest value in the sound absorption test is found in composites with a volume fraction of 40:60 with an STC value of 25, while the lowest value is found in composites with a volume fraction of 60:40 with an STC value of 11. Based on the results of this study, composite with a volume fraction of 40:60 is the best percentage in the sound absorption test because the greater the STC of a material, the better it is at absorbing sound.
