Abstract

AbstractThe research objectives are to (1) design Ozcel(Oz Care and Clean) usingozonization (2) to find out how it works and (3) to reveal its performance as an effortto substitute pesticides. The type of the research is a development research. Theprocess of making Ozcel covers designing, preparing the equipment and materials,making the electronic circuit of PWM driver, making a box and lay out, assembling theparts of Ozcel, and testing the function of Ozcel as a pest eradicator. The result of theresearch is the design of Ozcel (Oz Care and Clean) consisting of importantcomponents, which among other things are a motorcycle coil as a high voltagegenerator functioning as ozone gas generator and PWM circuit as the driver of the coil.The dimension of Ozcel is 25 x 15 x 15 cm. Ozcel works as the high voltage of the coilis generated to produce electric plasma. The oxygen is then flown through the plasmaand the oxygen will react to become ozone or O3. Based on the analysis of itsperformance, Ozcel (Oz care and clean), is shown to have an effcet on preserving fruitsafter the harvest. Ozcel makes the fruits and vegetables remain fresh longer. In thisway the preserving process is carried out without using preservatives and isenvironment friendly.

Abstract

This thesis contains an analysis to increase efficiency with production model re-layout using activity relationship chart. The research already done at manufacturing making wiring harness located in Balaraja, Tangerang with model carline Toyota Hiace. Based on existing layout, writer defines 21 facilities from beginning process (Pre-Assy) until end process (Inspection). For decide degrees of closeness, writer and stakeholder for the company do brainstorming to formulate 7 criteria for relevance motive table. Based 7 criteria, 21 each facilities can be decided degrees of closeness and mapped out in activity relationship chart. Degrees of closeness each facility can be divided into 6 levels as A (Absolute), E (Especially), I (Important), O (Ordinary), U (Unimportant), and X (Undesirable). Information of degree of closeness become a basis for making new layout more efficiency by using block tamplate but should be adjusted based on layout type production system. Type of layout that suitable is layout by product with improve efficiency from 63% to 65%.

Abstract

Hybrid learning is a learning method that combines or combines online learning with face-to-face learning (PTM). so that in its implementation, there are times when students and teaching staff meet face to face in class. However, in its implementation there are several obstacles, one of which is the number of students attending class and decreasing interest in learning, resulting in a poor final semester assessment. In connection with the problems faced, this research will try to measure interest in the hybrid learning model that has been implemented at Mulia University using the Multi-Attribute Utility Theory method, where this method is a decision-making method used to evaluate alternatives by considering several attributes. relevant and selecting the alternative that best meets the needs and preferences of the decision maker.

Abstract

Paving block merupakan komposisi bahan material bangunan yang terbuat dari campuran material semen, air, dan agregat. Penelitian ini menggunakan jenis plastik PP sebagai bahan material pengganti semen pada Paving block. Tujuan dari penelitian ini yaitu Untuk mengetahui karakteristik kuat tekan dari variasi bentuk Paving block dengan memanfaatkan plastik polipropilena (PP) sebanyak 50% sebagai bahan pengganti material semen, dan Mengidentifikasi kendala dalam pembuatan Paving block. Paving block diproduksi di Laboraturium Teknik Sipil Universitas Balikpapan, Kecamatan Balikpapan Selatan, Kota Balikpapan, Kalimantan Timur. Penelitian ini melibatkan variasi campuran plastik PP dan pasir dengan perbandingan berikut : 50% plastik PP : 50% pasir. Pengujian ini juga dilakukan di Laboratorium Teknik Sipil Universitas Balikpapan. Hasil penelitian ini dapat menunjukkan bahwa kuat tekan tertinggi terjadi pada bentuk heksagon campuran 50% plastik PP : 50% pasir, mencapai 16 MPa. Dari semua pengujian untuk bentuk balok, wajik, dan heksagon, dapat diketahui bahwa bentuk optimal dari pengujian ini adalah bentuk heksagon.
