Abstract

Eastern Indonesia has enormous potential for solar energy. For the utilization of this energy, data on the intensity of solar radiation is needed that can describe the availability of solar energy that can be utilized. Information on the availability of solar energy will be used to estimate the intensity of solar radiation, so that the use of solar energy can be optimal. In this study, the intensity of solar radiation was estimated. The data used to estimate the intensity of solar radiation were air temperature, humidity, duration of solar radiation, and rainfall. The method used in this study is an artificial neural network (ANN) with backpropagation training. This study uses variations in the number of neurons in 1 hidden layer to get the best group based on the RMSE value and correlation. The best group from each training simulation is then used to estimate solar radiation. The estimation results for the city of Jayapura have an RMSE value of 1,970 kWh/m2. The solar radiation received in the Jayapura area has a high enough potential to be used as alternative energy with an average monthly radiation value of 4,5 kWh/m2.

Abstract

The research has done using Multigamma Irradiation Method for genetic engineering on local jumbo peanut plants of the upright type Rote Ndao. This research has done in Oesapa Barat, Kelapa Lima District, Kupang City, East Nusa Tenggara. This study is to test the accuracy of the dose for improvement of local jumbo varieties of upright type peanuts irradiated with standard multigamma and to determine tolerance of irradiated mutant varieties to several environmental physical characteristics that are limited to temperature and also the humidity that are not suitable for local peanut growth conditions. The results showed that the right dose to obtain high produce of varieties is dose 4000. The superior characteristics obtained from a dose of 4000 rads included the fastest growing time, the highest number of pods per tree, the highest number of seeds in one pod, the highest protein content, the highest fat content, and the highest mass per 150 seeds. Humidity and temperature of the soil and air in the area planted with Rote Ndao jumbo local peanuts are tolerant of several environmental physical characteristics.

Abstract

This study aims to determine the compounds contained in limestone, identify the content and crystal phase of CaCO3 in limestone and determine the effect of heating temperature on the CaCO3 crystal phase in limestone using XRF and XRD methods. XRF test results show that the compounds contained in limestone in Manulai I village are CaO, Nb2O5, Cr2O3, MoO3, In2O3, SnO2, Sb2O3, RuO4, dan Na2O and XRD test results showed that the crystal phase of CaCO3 at a temperature of 5500C to 7500C was in the form of calcite. In limestone calcined at different temperatures, the intensity increases, this can be interpreted that the higher the calcination temperature, the higher the crystallinity.

Abstract

This research study is the determination of estimated distribution of subsurface leachate based on electromagnetic data in the Noinbila Final Disposal Site (TPA) area and its surroundings in South Central East Regency. The data used in the form of conductivity and susceptibility values ​​of the measurement results of the GF instrument CMD-4 at coordinate points at certain elevations. The data is processed and displayed in 2D and 3D contour maps with the help of several related software. The results of the analysis provide information that the Noinbila landfill area and its surroundings which are divided into areas A, B, C, D, E and F are not all polluted by leachate below the surface, but only areas D and F are suspected to be polluted. The potential for contamination of areas A, B, C and E below the surface is still possible because these areas have subsurface geology in the form of coral limestone. The potential for this pollution, apart from below the surface, is also possible on the surface because areas A, B, C and E have a lower elevation dominance than areas D and F. For this reason, this potential must be avoided by optimally handling and managing waste. If the handling and management of the waste is related to the efforts of the Noinbila TPA management, then it has been done even though it is still not optimal. The form of handling efforts as a form of waste management is in the form of matters related to the maintenance and repair of the TPA and its facilities and infrastructure, handling of waste before and after at the TPA and leachate water flow through pipelines to the holding pond, stabilization pond and leachate treatment pond.

Abstract

The design of several vehicles by changing the design of the vehicle body and household materials using composites has already been carried out in Indonesia using various methods and using natural materials that are easy to find. A unique motorcycle body design can give an attractive impression from the appearance of the motorcycle in use, seen from the new physical conditions with the image of a motorcycle that is easily engineered in such a way that it becomes an opportunity for motorcycle manufacturers to design motorcycle bodies with natural materials that can received potential market share. One of the natural materials that can be made or designed to be used as an alternative to composite raw materials as motor designs that are easy to find in the NTT region is one of them is palm fiber, whose use is still limited.

Abstract

Fish as a source of animal protein is a fishery commodity that is prone to quality deterioration and spoilage after the fish is caught, so it needs fast, precise and correct handling to keep its quality in the hands of consumers. There for it is necessary to have a process that extends the durability through drying. One drying alternative is to use a Solar Air Heater with an Ultra Violet (UV) Solar Dryer drying house by making a building made of transparent material that functions as an insulator so that the solar irradiation trapped in the building will increase its temperature. The accumulated heat is used to dry the fish. Sardines that have just been displayed are put into the drying chamber with various loads of 22.23 kg, 14.82 kg and 7.41 kg. The energy source for drying is from sunlight with the Solar Air Heater system. The results show that drying efficiency and thermal efficiency increase with the addition of drying load. The highest values ​​of drying efficiency and drying house efficiency occurred at the mass load of 22.23 kg of fish at 13.17% and 50.57% with the lowest specific energy consumption (KES) of 18947.421 kJ/kg. The average temperature and temperature difference both in the solar air heater and in the drying chamber increase with the addition of the drying load. This temperature increase increases the drying rate which can reduce the drying time.

Abstract

Energi Nuklir merupakan salah satu energi alternatif yang memiliki kelebihan pada jumlah energi yang dihasilkannya, bahan bakar yang digunakannya dan tidak menghasilkan pencemaran udara. Gas-Cooled fast Reactor merupakan reaktor cepat berpendingin helium yang termasuk dalam reaktor Generasi IV yang memiliki keunggulan dalam segi penggunaan bahan bakar dan keselamatan. Thorium merupakan salah satu bahan bakar nuklir yang bersifat fertile yang jumlahnya melimpah, yaitu empat kali lebih banyak dibandingkan dengan jumlah uranium. Perhitungan kekritisan desain reaktor cepat berbahan bakar thorium nitride (ThN) menggunakan seperangkat program SRAC yang menghasilkan kondisi kritis pada pengayaan uranium-233 sebesar 5% dengan nilai excess reactivity sebesar 0,044% pada fraksi volume 65% fuel, 10% cladding dan 25% coolant dan menghasilkan level burnup 1,93 x 105 MWd/ton. Bahan bakar thorium bisa digunakan sebagai bahan bakar nuklir untuk pembangkit listrik tenaga nuklir dengan waktu burnup 50 tahun.
