Abstract

The optimal use of libraries is through user education, because through this program users get a series of knowledge about information sources. One way to find out the success of a program is to do an assessment. This study aims to evaluate the implementation of user education that has been implemented in the Library of the Faculty of Engineering UGM. CIPP Model (Context, Input, Process & Product) used for evalution with  a qualitative approach. Research subjects were members of the UGM Faculty of Engineering who had attended user education programs and library management team. Data collection is done with documentation, interviews, and observations. The results showed (1) the Context evaluation was good, there was a match between the program with the vision and mission of the institution, (2) Evaluation of inputs was good, supporting facilities and facilities were adequate, (3) Process evaluation was sufficient, the implementation schedule needed to be improved, ( 4) Evaluation of the product is good, there is a certificate as a sign of following the activity by achieving the competency that has been set. The factors that support the implementation of the program are competency of human resources, communication, adequate facilities and infrastructure, and good cooperation with stakeholders. The factors that hinder the program are the schedule of activities that are not yet routine, those responsible for the program cannot be delegated to other people, there is no analysis of student needs, and there is no written policy on this program. The recommendation of this research is that it is necessary to improve several inhibiting factors so that the implementation of user education activities can run smoothly in accordance with the stated goals.

Abstract

Isolasi cair pada peralatan tegangan tinggi digunakan sebagai media pendingin peralatan listrik. Apabila tegangan yang diterapkan melebihi kekuatan dielektrik isolasi cair maka akan terjadi tegangan tembus yang menandakan kegagalan isolasi. Pengujian tegangan tembus terhadap minyak kemiri dan minyak zaitun dimaksudkan untuk mengetahui peluang minyak kemiri dan minyak zaitun sebagai alternatif pengganti minyak transformator. Pengujian ini berlandaskan standard IEC 156:1995 yaitu menggunakan elektrode setengah bola-setengah bola berukuran 50 mm dengan jarak sela 2,5 mm. Pengujian ini juga dilakukan dengan menggunakan 3 kali percobaan untuk mendapatkan nilai tegangan tembus .Hasil akhirnya nilai tegangan tembus minyak kemiri dan minyak zaitun pada kondisi standar sesuai IEC 156 sebesar 4,08 kV/2,5 mm dan 13,33 kv/2.5 mm Nilai ini belum memenuhi standar SPLN 49-1:1982 yaitu sebesar > 30 kV/2,5 mm. Tetapi masih memiliki peluang jika ditambahkan zat aditif fenol yang dapat menaikkan tegangan tembus minyak isolasi

Abstract

The Anggrek coal-steam power plant (PLTU) in gorontalo is anpower generation facility that utilizes coal as its primary energy source. In recent years, the energy industry has undergone significant changes, driven by the need to reduce greenhouse gas emissions and increase the utilization of renewable energy souces. Dried white leadtree wood, exposed to sunlight for 18 hours, has a moisture content of 40% and a high calorific value of 4,197 kcal/kg, making it suitable for blending with coal. This power plant applies co-firing, which involves blending 1-5% white leadtree woodwith 1,000 tons of coal daily. This study aims to analyze the electricity generated. Additionally, this study evaluates the needs and procurement of both coal and white leadtree, alongside the sales of electricity in kWh. The methodology involvescollecting monthly data on fuel consumption and cost estimates per kWh generated. The results indicatevthat coal accounts for 95% of the total fuel consumption, while white leadtree contributes only 5%. The estimated cost of purchasing coal for co-firing with white leadstree is IDR 520 per kg, whereas the selling price of electricity is IDR 2.500 per kWh.

Abstract

The development information of technology in the current era of globalization is very fast, this requires all companies in the world to be able to compete with each other. The competition in the bussiness world, forcing all of the companies to think of strategies and breakthroughs that can ensure the sustainability of the bussiness that they run of. PT VARTA MICROBATTERY INDONESIA is a company engaged producing battery-based materials. However, looking at the past years many series of battery models have been discontinued. Some series of battery models that have been stopped production. It’s difficult to obtain strategic information such as the level of sales per period, predictions of sales in the coming years, and sales of products produced. Availability large sales data in the database server are often not used optimally, therefore the sales data is only used for daily operational activities. Analysis is needed to see patterns from sales data so as to produce predictions of battery. That big data from customer can be analysis using data mining. The method to use as for predictions is C4.5 Algorithm based on decision tree. This mining activity is expected to provide a decision tree to see patterns of prediction consumer buying behavior the batteries. The results of this mining activity is getting 9 rules with size category knowing as a root and the sales via as a leaf.
