Abstract

The design of a biphenyl chemical plant from benzene with a capacity of 10,000 tons/year will be built in Tuban, East Java with a land area of ​​10,010 m2. The raw material in the form of Benzene is obtained from Trans-Pacific Petrochemical Indotama (TPPI), Tuban. The factory is designed to operate continuously for 330 days, 24 hours per day, and requires 214 employees. Biphenyl preparation begins with reacting benzene (2,807.74 kg/hour) in a Pipe Flow Reactor (R-01) at a reactor temperature of 377 oC and a pressure of 2 atm. This reaction takes place with a conversion of 90% and is endothermic so that a Hitech heater is used to maintain the operating temperature. The products that come out of the reactor are biphenyl and hydrogen. It is then cooled and condensed in a Partial Condenser (CD-01) to a temperature of 151 oC. Then enter into Separator-02 (SP-02) to separate hydrogen from a mixture of benzene, toluene and biphenyl. Hydrogen in the gas phase as a result of the separtor. The bottom product in the form of benzene, toluene and biphenyl in the liquid phase is pumped and put into a distillation tower (MD-01) to purify the product with the bottom product in the form of biphenyl with a purity of 99.3%. The result of the distillation tower is benzene and its impurities are recycled as feed into the reactor with a temperature of 83 oC and a pressure of 1 atm. This factory requires Fixed Capital (FC) Rp. 34,341,856,338,- + US$ 4,195,836, Working Capital (WC) (Rp. 127,536,505,173,- + US$ 170,019), Manufacturing Cost (MC) (Rp. 254,092,040,390,- + US$ 816,090), and General Expenses (GE) (Rp. 33,990,417,539,- + US$ 81,609). Economic analysis shows the value of ROI before tax is 50.38 % and the value of ROI after tax is 32.75%. POT before tax is 1.65 years and POT after tax is 2.34 years. The BEP value is 43.11% and the SDP value is 23.75%. The interest rate in DCF for 10 years is 19% on average. Thus, from a technical and economic point of view, a biphenyl plant from benzene with a capacity of 10,000 tons/year is worthy of consideration.

Abstract

Museum is an institution intended for the general public whose function is to collect, maintain, and present and preserve the cultural heritage of the community for research, education, recreation, and exhibition purposes. Regionalism architecture is an architecture that advocates the appearance of a building which is the result of a compound of internationalism with modern cultural and technological patterns, values ​​and nuances of tradition that are still embraced by the local community. The Patiayam Archaeological Site is an ancient site in the Patiayam Mountains, Kancilan Hamlet, Terban Village, Jekulo District, Kudus Regency. About 4,000 fossils were found in Patiayam. Some of the elephant tusks are placed in the Ronggowarsito Museum, Semarang. With so many fossils, it will not be stored properly because there is not enough space. If this continues, it is not impossible if the fossil which is a cultural heritage will become extinct. This study aims to provide a planning concept for the Patiayam Kudus Archaeological Museum.

Abstract

For thousands of years, humans have felt the need to understand the world around them—and ultimately manipulate it to best serve their needs. There are always ethical questions to address, especially when the manipulation involves the human genome. There is currently an urgent need to actively pursue those conversations as com- mercial gene sequencing and editing technologies have become more accessible and affordable. Gene Editing has enormous potential both as a research tool and a therapeutic intervention. While other types of gene editing are relatively uncontroversial, gene editing has been strongly resisted.

Abstract

Colorectal cancer are the third most commonly diagnosed form of cancer globally, which about 11% of all cancer diagnoses. Obesity, together with kind of sedentary lifestyle, red meat consumption, tobacco, and alcohol consumption are considered as predisposing factors of progression of CRC. In the development of colorectal cancer, genetic factors having a role in its incidence. The hereditary type of colorectal cancer was divided into two types is polyposis and Lynch syndrome which have each and different mechanism and genetic pattern. Lynch syndrome contributes for 3–5% of CRC cases and is caused by a germline mutation in one of four genes associated with the DNA mismatch repair (MMR) system: MLH1, MSH2, MSH6, or PMS2. In polyposis, there are some types such as Familial Adenomatous Polyposis (FAP) which mostly caused by APC mutation, MYH-associated polyposis, and the rare hamartomatous polyposis syndromes. Genetic testing and better family history documentation can enable those with a hereditary predisposition for the neoplasm to take preventive measures. Some genetic testing can be used such as Microsatellite instability (MSI), immunohistochemistry (IHC), DNA sequencing and protein truncation that used for each type of hereditary colorectal cancer.

Abstract

Butyrylcholinesterase (BChE) is an enzyme found in plasma and many other parts of the body. It is enzyme that hydrolyses drugs containing ester bonds such as drugs acting at the neuromuscular junction (succinylcholine) and local anaesthetics (procaine). Examination of the gene for mutations or polymorphisms causing the observed biochemical phenotypes has isolated those responsible for all the most widely known variants. The molecular bases of several genetic variants of BChE have been reported, such as the Atypical variant, fluoride-resistant variant, silent variant, K variant, J variant and C5 variant. In general, BChE polymorphisms have been shown to produce enzymes with varying levels of catalytic activity. Genetic variants of human butyrylcholinesterase were one of the first examples in the new field of pharmacogenetics when it was recognized that abnormal response to the succinylcholine was due to a mutated enzyme with low binding affinity. Beside that, variant of BChE has potential impact for Alzheimer disease patology

Abstract

Enzyme immunoassay (EIA) and enzyme-linked immunosorbent assay (ELISA) are both widely used as diagnostic tools in medicine and as quality control measures in many industries. ELISA has been the system of choice when testing soluble antigens and antibodies. EIA / ELISA uses the basic immunological concept of antigen binding to specific antibodies, which allows the detection of small amounts of antigens such as proteins, peptides, hormones or antibodies in fluid samples. In all protocols, solid-phase reagents are incubated with secondary or tertiary reactants covalently coupled with the enzyme. The unbound conjugate is washed and a chromogenic or fluorogenic substrate is added.

Abstract

Modern technology today, especially in the world of technology Robots are developing very rapidly. Many developed countries are competing and vying to make increasingly sophisticated robots. In Indonesia, robots have also begun to develop. Developments in the field of robotics are also able to have a positive impact in the industrial sector. One example is the process of moving an item/object from one place to another. This study aims to test the motion system, namely a DC motor that functions as a motor for carrying goods. The method used is input from commands given by the user via a smartphone with voice access. As an intermediary, a bluetooth connection is used so that commands can be sent from a smartphone to the control circuit. The controller used is the AVR type, namely atmega 328 on the Arduino Uno board. At the output, there are relays and current amplifiers that function as motor drivers. The user will give orders via a smartphone where on the smartphone runs an application, namely a voice to text converter. The application will convert the human voice into text and send via bluetooth to the controller. The Arduino controller will identify the command code and execute it, namely controlling the robot's motion in the direction desired by the user, for example forward, backward left and right or towards a predetermined point.
