Abstract

The study aims to evaluate the testing methods Total Plate Count (ALT) which is easierand faster is Petrifilm Aerobic Plate Count (PAPC) against resistance in TPC testing infishery products, as well as compliance with the Indonesian National Standard (SNI) 012332.3-2006.This study held in Laboratory Quality Control and Testing of FisheryProducts (LPPMHP) Surabaya, East Java. This study three types of cultures breed bacteriaand 24 types of fishery products by using two methods of testing, as the reference test SNI01-2332.3-2006 and in comparison to the PAPC. The results of the test, then analyzedusing statistical calculations to evaluate the suitability of the ISO 4833 test method.Finally, note that ALT testing using PACP in accordance with ISO 01-2332.3-2006 as astandard method of testing, and has a good fit in the ALT test with a sample of fisheryproductsKeywords : total plate count, ISO 4833, petrifilm aerobic count plate, SNI. 01-2332.3-2006

Abstract

The competence in predicting financial distress becomes an important research due tothe advantage in preventing companies financial failure. Besides, financial distressprediction model will give benefit to the investors and creditors. This research developa financial distress prediction model for listed manufacturing companies in Indonesiausing Support Vector Machines (SVM). Mathematically, SVM is formulated in the formof quadratic programming, which requires high computational time in finding theoptimal solution. In this research, Cross Entropy (CE) is used to optimize one of theSVM’s parameter that is Lagrange multipliers to find the optimal solution or nearoptimal solution of dual Lagrange SVM. The accuracy of the prediction model andcomputation time will be compared between standard SVM and CE-SVM. Finally, notethat the CE-SVM can solve classification problems in computing time 9.7 times shorterthan the standard SVM with good accuracy results. Keywords: cross entropy, lagrange multipliers, support vector machines, financialdistress

Abstract

To make Kenjeran coastal areas as the mainstay tourism Surabaya municipaladministration, provision of clean water is one of the means that must be provided.Construction of sea water purification unit with sea water reverse osmosis method isone solution that can be done. This study aims to assess the feasibility of building awater purifier sea with sea water reverse osmosis method. Finally found that for aninterval of 15 years at an average rate of visitor arrivals tourist attraction as much as7,935 people / day needed clean water supply as much as 257.09 m3 / day, equivalent to10.71 m3 / hour. Average investment value of Rp. 5.5 billion with 19:38% IRR ratemuch higher than bank interest, which is 10%. Break Even Point investment occurred inyear 7 in 2023. Keywords: investment feasibility, Sea Water Reverse Osmosis, coastel tourism area

Abstract

In order to always meet their daily needs, the amount of water in the reservoir mustalways be maintained, which shall not be less than the minimum and not higher than themaximum limit. Thereby filling reservoir must be controlled. From the number of unitscontrolling water level in the reservoir turns encountered many disadvantages. Thisstudy aimed to innovate controller unit as perfecting the control unit that had beenthere. The control unit is designed to use a water level sensor. With SWOT analysis andLikert scale analysis eventually showed that the new control unit has a goodperformance and can be accepted by the public.Key Words: innovation, control, swot, Likert

Abstract

The rapid development of CNC machine technology, often makes the inequality ofknowledge between the world of vocational education (SMK) and the world of industry.Along with the development of computer technology is so fast, now born as CNCmachines with the latest generation Mitsubishi-based, Fanuc-based, or GSK-basedoperating system. Meanwhile in the world of education is still using EMCO-based. Noteasy for SMK to follow developments. Financial constraints is one of classic factors.This study tries to deal with this inequality without being affected by financialconstraints, namely by replacing the engine-based laboratory with a simulator-basedlaboratory. To test whether this simulator is able to overcome inequality, then thetreatment of the two groups were paired consisting of teachers and students. By testingthe hypothesis Ho: μ1-μ2 = 0, and by using a Likert index analysis known that the CNCsimulator is able to replace the actual existence of a CNC machine. It mean thatinequality can be solved immediately.Keywords: inequality, CNC machining , vocational education, CNC simulator
