RANCANG BANGUN ALAT PENETAS TELUR OTOMATIS MENGGUNAKAN ARDUINO NANO

Chicken farming is one of the most important industries in our country. Meanwhile, in chicken farming, breeders usually do not keep up with technological developments, breeders sometimes still use improvised tools for the process of hatching chicken eggs. Sometimes there are many obstacles experienced in hatching chicken eggs, namely incubators that only use incandescent lights without any tools to regulate the humidity in the egg area because basically chicken eggs also need stable humidity for maximum results, there is no tool that can tell the temperature at chicken eggs are enough or excessive, and there is a lack of attention in hatching the chicken eggs. So it is not controlled when the eggs have hatched and the incubator situation is not controlled during the chicken egg hatching process. And in this research the author aims to regulate the temperature and stabilize the humidity of the eggs in the egg environment so that the eggs can hatch with good quality using the Arduino Nano microcontroller

The influences of basic physical properties of clayey silt and silty sand on its laboratory electrical resistivity value in loose and dense conditions

Non-destructive test which refers to electrical resistivity method is recently popular in engineering, environmental, archaeological and mining studies. Based on the previous studies, the results on electrical resistivity interpretation were often debated due to lack of clarification and evidences in quantitative perspective. Traditionally, most of the previous result interpretations were depending on qualitative point of view which is risky to produce unreliable outcomes. In order to minimise those problems, this study has performed a laboratory experiment on soil box electrical resistivity test which was supported by an additional basic physical properties of soil test like particle size distribution test (d), moisture content test (w), density test (ρbulk) and Atterberg limit test (LL, PL and PI). The test was performed to establish a series of electrical resistivity value (ERV) with different quantity of water content for clayey silt and silty sand in loose and dense condition. Apparently, the soil resistivity value was different under loose (L) and dense (C) conditions with moisture content and density variations (silty SAND = ERVLoose: 600 - 7300 Ωm & ERVDense: 490 - 7900 Ωm while Clayey SILT = ERVLoose: 13 - 7700 Ωm & ERVDense: 14 - 8400 Ωm) due to several factors. Moreover, correlation of moisture content (w) and density (ρbulk) due to the ERV was established as follows; Silty SAND: w(L) = 638.8ρ-0.418, w(D) = 1397.1ρ-0.574, ρBulk(L) = 2.6188e-6E-05ρ, ρBulk(D) = 4.099ρ-0.07 while Clayey SILT: w(L) = 109.98ρ-0.268, w(D) = 121.88ρ-0.363, ρBulk(L) = -0.111ln(ρ) + 1.7605, ρBulk(D) = 2.5991ρ-0.037 with determination coefficients, R2 that varied from 0.5643 – 0.8927. This study was successfully demonstrated that the consistency of ERV was greatly influenced by the variation of soil basic physical properties (d, w, ρBulk, LL, PL and PI). Finally, the reliability of the ERV result interpretation can be enhanced due to its ability to produce a meaningful outcome based on supported data from basic geotechnical properties

Critical issues on Islamic banking and financial markets : Islamic economics, banking and finance, investments, Takaful and financial planning

This book examines the principles and practices ofIslamic banking and financial markets, particularly from the Malaysian experience. The main objective of Islamic financial system is to govern the flow of funds from the surplus sector to the deficit sector and it does so to promote justice ('adalah). That is, by adhering to Shariah principles and achieving efficiency - doing the right thing and doing it right, public and private interest interests are can both be protected. By doing so, the legal and moral dimensions of product design and development are now equally important. In this way halal status should not discount how Islamic products affects general economic activities. It means that Shariah advisors should not only approve Shariah complaint products along the juristic plane but dutifully consider how the products can affect income disparities and poverty, economic stability and growth. For this reason, the principle of risktaking (ghorm) and the principle of work (kasb) and the principle of liability, accountability, responsibility (daman) are paramount in determining Shariah legitimacy of profits and earnings derived from Islamic financial transactions. Risk (ghorm), work (kasbh) and liability (daman) constitute the essence of trading and commerce (ai-bay') the Holy Quran has enjoined over usury (riba). By risk, it means allowing capital to depreciate and appreciate as dictated by the market forces. By work, it refers to value-additions namely, knowledge and skills imparted into the business process. Liability means the responsibility each party must assume in the contract such as providing warranties on the goods and services sold. Based on these principles ofrisk, work and responsibility, also known as the principle of equivalent countervalue ('iwad), the ethical and moral dimension of Islamic fmancial transactions can be realized and thus promote the sense of justice the Quran attempts to convey. It helps people take a second-look at financial products that have received Shariah compliant status and help control potential duplication of interestbearing products bearing the Islamic label

The optimization of heating temperature for carbon extraction from peat soil

This study aims to find the optimised heating temperature for carbon extraction from peat soil. Ccarbon from peat soil was extracted by the pyrolisation process at temperature, T = 200, 300, 400, 500, 600 and 700°C for 5 hours. The carbon, C and silica, Si content extracted from peat soil at various heating temperatures were measured by using an Energy Dispersive X-Ray analyzer (EDX) at 3 points on the sample surface. High atomic percentage of carbon (95.44 %) was measured at T = 400°C, while the highest atomic percentage of silicon was recorded at T = 700°C (30.79 %). The surface morphology of peat soil was analysed using Scanning Electron Microscope (SEM) at 800 magnifying power, and it was clearly seen that peat fragments were pyrolised at high heating temperature with pores enhancement. The molecular structure parameter of the extracted carbon were identified using Laser Raman analysis. The peak positions of D-band and G-band for raw peat soil were observed at Raman shift of 1379.62 and 1549.02 cm-1, respectively. Meanwhile, the D-band for peat soil heated at temperature of 400°C was 1391.56 cm-1 whereas the G-band has peak position at 1562.16 cm-1 . From the Raman spectra of the optimum heating temperature at 400°C, it was revealed that the carbon molecular structure from the peat soil is mainly attributed by graphite and diamond structure

Using tourism as a mechanism to reduce poaching and hunting: a case study of the Tidong community, Sabah

"In Sabah, Malaysia, illegal hunting has increased in recent years putting considerable pressure on large mammal populations. The causes for this phenomenon lie in increasing rural poverty, ineffective policies to regulate hunting, as well as a ready market for many wildlife products in the Chinese medicine markets. This paper examines how Community-Based Ecotourism has some potential to be used as a tool to reducing poaching using the Tidong community in Sabah as a case study. The key finding is that successful conservation outcomes for Community-Based Ecotourism projects are only sustainable over the long run if projects are structured to ensure that the local community is able to continue effective management once sponsoring organizations hand over control and that revenue from tourism does not decline. If tourist revenue declines communities may be forced to revert to previous practices reversing any initial conservation gains.

Wavelet neural networks applied to pulping of oil palm fronds

In the organosolv pulping of the oil palm fronds, the influence of the operational variables of the pulping reactor (viz. cooking temperature and time, ethanol and NaOH concentration) on the properties of the resulting pulp (yield and kappa number) and paper sheets (tensile index and tear index) was investigated using a wavelet neural network model. The experimental results with error less than 0.0965 (in terms of MSE) were produced, and were then compared with those obtained from the response surface methodology. Performance assessment indicated that the neural network model possessed superior predictive ability than the polynomial model, since a very close agreement between the experimental and the predicted values was obtained

Stiffness modulus properties of hot mix asphalt containing waste engine oil

This study presents the effect of waste engine oil (WEO) on the mechanical properties of hot mix asphalt mixtures containing waste lubricating WEO. It was added into mixture at 0%, 3%, 5%, 7%, 10% and 15% by weight of binder. The mechanical properties of the mixes were evaluated by conducting indirect tensile stiffness modulus (ITSM) at temperatures of 25°C and 40°C. The results indicated that modified mixes exhibited lower stiffness modulus with the increasing amount of WEO as well as testing temperature. The increasing amount of WEO was found to have a good linear correlation to the decreasing of stiffness modulus. The finding showed that the WEO has the significant role as a softening agent which affected the stiffness modulus even at low percentag
