Metode Peningkatan Ketahanan Retak Resin Polyester Terhadap Penambahan Serat Sekam Padi

Polymer materials have been widely developed as alternative materials to replace metal materials due to various advantages such as having low density and an easy manufacturing process. Still, polymers have many disadvantages, including not having high mechanical strength, easy to crack when hit by impact. One of the materials studied is an unsaturated polyester polymer widely used for composite matrices in vehicle structural components, aircraft and ship bodies, and vehicle components.  One of the studied fibers is rice husk particle fiber. The study of cracks is essential because it causes the material to no longer be able to support the load according to the previous plan and causes failure to occur more quickly. One way to overcome material failure due to cracks in the composite material is to prevent crack propagation by adding reinforcing material. In this study, a composite material was made using rice husk fiber to increase the crack resistance of the polyester composite matrix. From the results of crack testing, there is a tendency to increase the percentage of rice husks by 5%, 10%, 15%, and 20%. The value expected to be obtained for determining the crack resistance of the material is the value of the stress intensity factor (K1). The most significant K1 value was obtained at a 15% rice husk percentage variable of 1,558 MPa.m0.5. This price could increase the value of the pure polyester stress intensity factor K1 by 0.667 MPa.m0.5, indicating an increase of 233.58%

Metode Penurunan Respon Dinamik Sistem Poros-rotor Dengan Peredam Viscous Rotary

Viscosity or viscosity is one of the quantities that are very important in the analysis of the behavior and movement of fluids that come into contact with other objects such as solids {solid body). Viscous dampers can be used to reduce the amplitude of the response due to the unbalanced mass, rotation critically, noise and shock loads. Absorbers working with fluid film bearing securities which are placed at a certain point, which is connected to the shaft-rotating rotor. Certain viscosity fluid will be forced to pass through a narrow slit with a certain pressure that can absorb the energy supplied by the shaft, this damping effects that can provide resistance to the rotor shaft system because the fluid has a linear damping and damping effect histeriktik. Viscous dampers can be used to reduce vibration amplitude response at a fixed price in accordance with the physical nature of the damper, the use of viscous dampers are widely used to control engine speed and turbine rotational speeds are like a helicopter rotor. From the test we can produce the damping effect on the engine rotation can reduce the response time domain vibration with an amplitude reduction of approximately 60% for the damping ratio ζ = 0.5

Human being is the highest creature among all creatures. Even, he is higher than the world and it is very important for it. The perfection of the world depends on him. Human being in relation to the universe is like spirit for body.The world without human being is like a unclear mirror which can not refract a picture. The picture of God can not be seen in the mirror cleary so God command that the clear mirror of the world can refract His picture clearly. The human being is the clearness of mirror and the shape of the picture.The most perfect mirror for God is the perfect human being because he refracts all the names and the behaviour of God However, other refract only a few parts of the parts of the names and the behaviour of God.The perfect human being, faces all existances of individualism. Spiritually he faces higher individualism; the body he faces lower individualism. His heart faces to (al-Arsh). His soul faces to apen (Al-Qalam) and his spirit faces (luah-Mahfudz

Penduga Maksimum Likelihood untuk Parameter Dispersi Model Poisson-Gamma dalam Konteks Pendugaan Area Kecil

The Poisson-Gamma (Negative Binomial) distribution is considered to be able to handle overdispersion better than other distributions. Estimation of the dispersion parameter, φ, is thus important in refining the predicted mean when the Empirical Bayes (EB) is used. In GLM’s sense dispersion parameter (φ) have effects at least in two ways, (i) for Exponential Dispersion Family, a good estimator of φ gives a good reflection of the variance of Y, (ii) although, the estimated β doesnt depend on φ, estimating β by maximizing log-likelihood bring us to Fisher’s information matrix that depends on its value. Thus, φ does affect the precision of β, (iii) a precise estimate of φ is important to get a good confidence interval for β. Several estimators have been proposed to estimate the dispersion parameter (or its inverse). The simplest method to estimate φ is the Method of Moments Estimate (MME). The Maximum Likelihood Estimate (MLE) method, first proposed by Fisher and later developed by Lawless with the introduction of gradient elements, is also commonly used. This paper will discuss the use of those above methods estimating φ in Empircal Bayes and GLM’s of Poisson-Gamma model that is applied on Small Area Estimation.

KAJIAN PENGERING GABAH DENGAN WADAH PENGERING BERBENTUK SILINDER DANMEKANISME PENGADUK PUTAR

Rice yield in this market are still drained manually by using the power of the Sun and drying process is done in a long time. Moisture content of the product is not uniform, and the resulting dried grain capacity is limited, because it requires a big place in the drying process. Rice dryers available on the market have not been manufactured with quality drying is not good because of the uneven results of drying and drying inefficient. With the above background, the dryer can be designed to work in continuous material and product is can occur at any time. Equipment dryers are equipped with commutator so that drying can take place constantly. Testing is done is to take a sample of every 1 kg of rice and measured levels of moisture content. Drying characteristics of optimization testing is to control the speed of the stirrer shaft, and evaluate the results of testing the uniformity of drying is to divide the result of drying to 8 mass fraction is then weighed their respective weight. Tests using rice dryer drum drying with a stirring mechanism, it can be concluded that the decrease in moisture content and degree of drying and drying time is affected by the speed of rotation of the agitator shaft is linear. Testing is done by varying the agitator rotation rpm 30, 35 and 40 rpm rpm. On lap 40 rpm going very fast drying results in the material to be cracked. In this study, drying time is used for drying rice as much as 8 kg with a level of 24% to 14% is 30 minutes with stirring speed 35 rpm,and the uniformity of drying results 86.6%

Regresi Rasio Prevalensi dengan Model Log-Binomial: Isu Ketakkonvergenan

Regresi logistik memainkan peran sentral dalam pengamatan epidemiologi. Regresi logistik memiliki odds ratio yang memberikan informasi tentang risiko seseorang didapati sebagai penderita suatu penyakit. Pada kasus tertetu ratio prevalensi dapat didekati dari odds ratio, dan tidak memberikan perbedaan yang menyesatkan. Namun odds ratio tidak selalu diinginkan. Antara lain, karena pada pengamatan common event (pengamatan dengan nilai 1 yang banyak), rasio prevalensi tidak lagi dapat didekati secara langsung dari odds ratio, artimya odds ratio tidak lagi mencerminkan informasi yang diinginkan oleh epidemiologi. Untuk itu diperlukan pendekatan lain dalam memperoleh ratio prevalensi dari data binomial, antara lain dengan model log-binomial/regresi relative risk/rasio prevalensi. Regresi log-binomial, dalam terminologi Model Linier Umum adalah model dengan distribusi Y binomial yanag menggunakan link-function log, sedangkan regresi logistik, menggunakan fungsi link, logit. Pada regresi log-binomial selain masalah ketakkonvergenan, dimungkinkan terjadi pendugaan peluang diluar interval 0-1, karena model ini tidak melakukan restriksi 0<=P(Y=1)<=1, seperti pada model logistik. Akibatnya, pada saat memodelkan pengamatan dengan P(Y=1) ≅ 1 atau rasio prevalensi mendekati 1, mungkin terjadi masalah. Penelitian ini ingin mengatasi masalah ketakkonvergenan pada log-binomial melalui metode copy (Copy Method) melalui suatu studi kasus penderita Demam Berdarah Dengue (DBD) di RSUD Dr. Soebandi Jember. Tulisan ini membicarakan tenang isu masalah ketakkonvergenan pada log-binomial, dengan alternatif penyelesaian menggunakan metode copy (Copy Method). Studi kasus diberikan sebagai ilustrasi data penderita Demam Berdarah Dengue (DBD) di RSUD Dr. Soebandi Jember. Kata Kunci: Regresi Rasio Prevalensi, Risiko Relatif, log-binomial, ketakkonvergenan
