Maximising utility savings through appropriate implementation of combined heat and power scheme

Combined Heat And Power (CHP) Scheme, Also Known As Cogeneration Is Widely Accepted As A Highly Efficient Energy Saving Measure, Particularly In Medium To Large Scale Chemical Process Plants. The Advantages Of A CHP Scheme For A Chemical Plant Are Two-Fold: (I) To Drastically Reduce Electricity Bill From On-Site Power Generation (Ii) To Save On Fuel Bills Through Recovery Of The Quality Waste Heat From Power Generation For Process Heating. In Order To Be Effective, A CHP Scheme Must Be Placed At The Right Temperature Level, In The Context Of An Overall Process System. Failure To Do So Might Render A CHP Venture Worthless. This Paper Describes The Procedure For An Effective Implementation Of A CHP Scheme Using An Ethyl Benzene Process As A Case Study. A Key Visualisation Tool In Pinch Analysis Technique Known As The Grand Composite Curve Is Used To Guide CHP Integration, And Allows It To Be Optimally Placed Within The Overall Process Scenario. The Study Shows That Appropriate CHP Integration With The Ethyl Benzene Process Above The Pinch Can Potentially Result In Significant Savings On Electricity Cost Of Up To 87%

PELATIHAN PENGUATAN PENDIDIKAN KARAKTER SANTRI DI LINGKUNGAN PONDOK PESANTREN TAHFIDZ DI ERA DIGITAL

Pendidikan karakter menjadi alternatif dalam membangun karakter anak bangsa yang saat ini telah mengalami persoalan serius terutama di era digital saat ini. Adapun tujuan pelatihan penguatan pendidikan karakter adalah mempertahankan nilai-nilai karakter santri, yakni keikhlasan, kesederhanaan, kemandirian, persaudaraan yang kuat, dan mengamalkan amar ma’ruf nahi munkar yang berpedoman pada Al Qur’an dan Hadits. Pondok Pesantren ini merupakan Pondok Pesantren Tahfid. Santri sudah mempunyai bekal dalam mengamalkan perilaku kehidupan sesuai dengan Al-Qur’an dan sunnah. Berpedoman pada Al-Qur’an di era digital sekarang dapat membantu orang tua dalam pembentukan karakter masing-masing anak. Era digital sekarang ini memiliki pengaruh yang besar bagi karakter, pendidikan, serta perilaku anak di zaman sekarang. Pada saat ini, banyak  remaja yang terjerumus keluar syari’at dikarenakan pergaulan bebas. Salah satunya adalah pemanfaatan telepon genggam, karena sudah seperti benda yang wajib dimiliki, tak terkecuali anak-anak di bawah umur yang bahkan belum bisa membaca ataupun menulis, mereka sudah mengenal yang namanya telepon genggam. Adapu salah satu kontribusi pembentukan karakter dalam pelatihan ini adalah mengajarkan kepada santri, tentang bagaimana cara mengunakan handphone dengan benar, membekali siswa terkait dengan kenakalan remaja saat ini dan juga untuk mengajarkan kepada anak anak cara untuk mengkaji dan mengamalkan Al-Qur’an dalam kehidupan sehari-hari. Salah satu bentuk pemanfaatan telepon genggam yang dilakukan pada pelatihan ini adalah sebagai sarana entrepreneur dan juga Al Qur’an yang menjadi pedoman dalam usaha. Santri bisa memanfaatkan fasilitas berbasis digital menjadi sesuatu yang lebih bermanfaat bagi hidupnya dan membangun jiwa Al Qur’an dalam hatinya.Kata Kunci: Pondok pesantren tahfidz, Era digital, Telepon genggam, Al-Qur’an, Entrepreneu

An Interacting Scenario for Dark Energy in Bianchi Type-I Universe

We study the interaction between dark energy (DE) and dark matter (DM) in the scope of anisotropic bianchi type I space-time. First we derive the general form of the dark energy equation of state parameter (EoS) in both non-interacting and interacting cases and then we examine it's future by applying a hyperbolic scale factor. It is shown that in non-interacting case, depending on the value of the anisotropy parameter $K$, the dark energy EoS parameter is varying from phantom to quintessence whereas in interacting case EoS parameter vary in quintessence region. However, in both cases the dark energy EoS parameter $\omega^{de}$, ultimately (i. e at $z=-1$) tends to the cosmological constant ($\omega^{de}=-1$). Moreover, we fixed the cosmological bound on the anisotropy parameter $K$ by using the recent observational data of Hubble parameter.Comment: 12 pages, 6 figures, Research in Astronomy and Astrophysics, 201

Peningkatan Hasil Belajar Menentukan Nilai Tempat dengan Menggunakan Media Papan Nilai

The purpose of this research is to assess the improvement of students learning outcomes to determine the value of place in class IV Elementary School of Extraordinary (SDLB) Tunagrahita light. This research used two cycles of learning materials to determine the value of the place, (1) to demonstrate the scoreboard media, (2) to determine the value by using media boards place value, (3) to determine the place value of hundreds, tens and ones by using media scoreboard special. The results of data analysis showed the learning to determine the value of the place affects the improvement of student learning outcomes : 1) to facilitate students in determining the value of the place, to improve the smoothness of the material in determining the value of the place. 2) to increase students' understanding of the material determine the value of the place, and 3) to increase students interest and motivation to determine the value the material points

Subcritical and supercritical fluid extraction a critical review of its analytical usefulness

Subcritical R134a is suggested as a low-pressure alternative to supercritical CO2 in the supercritical fluid extraction technology in particular of palm oil application. Therefore, a measurement of solubility of palm oil in subcritical Rl34a will be carried out at temperatures of 40, 60, 70 and 80°C and pressures up to 300 bar. The solubility of carotene are also will be measured using UV Spectrophotometer. Results obtained from this study will be compared with the previous work and for the first time, simulation for the SFE process of palm oil will be performed using Artificial Neural Network (ANN) and it will be implemented in comparisons as well when the operating conditions of the previous findings are different from this study. It is expected that the solubility of the palm oil in subcritical Rl34a is much higher than SC-C02, and it is expected that R134a could be a viable alternative solvent to supercritical carbon dioxide as R134a could be perform well at a lower pressure used whereas can achieved a higher solubility compared to SC-C0
