While investigating high-efficiency responsive driveability accompanied by low exhaust emissions, a new concept in engine control has been developed. The method is based on the direct monitoring and controlling of combustion conditions in engines, using a newly developed combustion pressure sensor. Fibre-optic technology is adapted to this sensor to produce a high noise immunity and a simple structure that facilitates applications in automotive engines. A sensing method to obtain information on engine output, knocking or detonation and the combustion temperature from the signal of the combustion pressure sensor has been proposed. A control system for the engine and powertrain control using this sensing method has been put forth to provide a remarkable improvement in engine and powertrain characteristics.

The next generation of free-turbine engines in the 2 to 5-lb/sec airflow class will undergo vast improvements in performance and efficiency. The improvements will be achieved concurrent with overall reductions in size and weight. Effort is required at optimization and miniaturization of the engine control system to keep pace with these improvements. This paper describes a conceptual design of an advanced engine control system for this class of engine. It provides gas generator and power turbine control with torque, temperature, load sharing and overspeed limiting functions. The control system was concepted to accommodate, with minimum hardware changes, such variants as regenerative cycle and/or variable power turbine geometry. In addition, considerations for closed and open loop modes of control and fluidic, electronic and hydromechanical technologies were studied to best meet a defined specification and a weighted set of evaluation criteria.

<p><em>Dissolved oxygen levels in water will affect water quality directly and indirectly for fish life as well as conditions in the water environment, therefore, it is very important to control water quality for adequate dissolved oxygen levels, because this plays an important role in the health condition of the environmental ecosystem for fish nurseries. Researchers usually measure and monitor water quality using measuring instruments that are widely sold in the market, for conditions of decreasing dissolved oxygen levels in fish nurseries tank can usually be controlled by adding an air bubble machine to the water using an aerator machine. Giving air bubbles to water is an effort to control the conditions for the adequacy of dissolved oxygen in the water, and the best system is to carry out a continuous control system regarding water quality, sometimes the oxygen condition in the water is sufficient for the standard of dissolved oxygen in water. However, the blower blower is still running, this is less effective because it requires unnecessary electrical energy or wastes energy. Analysis of the aerator engine control system is needed to make a design as to what state the aerator engine should be turned on. Analysis of the aerator engine control system can be done by measuring the level of oxygen and water temperature in the fish nursery tank, then designing a fuzzy model with the Sugeno inference system for how long the engine must be turned on. The analysis and design of this aerator system is a proposed solution to these problems with a system of measurement and monitoring carried out intelligently by a machine, so that it is able to measure how late this aerator machine must be turned on. and the developed design is capable of being a smart machine using a fuzzy system</em></p><p><strong><em>Keywords</em></strong><em>: Fuzzy inference, aerator engine, smart system, water quality.</em></p><p><em>Kadar oksigen terlarut dalam air akan mempengaruhi kualitas air secara langsung dan tidak langsung bagi kehidupan ikan juga keadaan di lingkungan air tersebut, oleh karena itu peningkatan kualitas air untuk keadaan kecukupan kadar oksigen yang terlarut sangat penting untuk dikontrol, karena hal ini berperan penting pada kondisi kesehatan ekosistem lingkungan pembibitan ikan. </em><em>Para peneliti biasanya melakukan pengukuran dan pemantauan kualitas air dengan menggunakan alat ukur yang banyak di jual dipasaran, untuk kondisi menurunnya kadar oksigen yang terlarut pada kolam pembibitan ikan biasanya dapat di kontrol dengan menambahkan mesin gelembung udara pada air menggunakan mesin aerator. Pemberian gelembung udara pada air merupakan salah satu upaya untuk mengontrol kondisi kecukupan kadar oksigen yang terlarut di dalam air, dan sistem yang terbaik yaitu melakukan sistem kontrol secara terus menerus mengenai kualitas air, terkadang kondisi oksigen di dalam air telah mencukupi standar kecukupan oksigen terlarut pada air, namun mesin penyembur gelembung udara masih dinyalakan, hal ini menjadi kurang efektif sebab akan membutuhkan energi listrik yang tidak semestinya atau terjadinya pemborosan energi. Analisis sistem pengontrolan mesin aerator dibutuhkan untuk melakukan desain seperti apa sebaiknya keadaan mesin aerator dihidupkan. Analisis sistem pengontrolan mesin aerator ini dapat dilakan dengan mengukur tingkat kadar oksigen dan suhu air pada kolam pembibitan ikan, kemudian melakukan perancangan model fuzzy dengan sistem inferensi sugeno seberapa lama mesin harus dihidupkan. Analisis dan desain sistem aerator ini merupakan usulan solusi permasalahan tersebut dengan sistem pengukuran dan pemantauan dilakukan secara cerdas oleh mesin, sehingga mampu mengukur seberapa lalma mesin aerator ini harus dihidupkan desain alat ini juga diharapkan mampu memberikan solusi peningkatan kualitas air pada pembibitan ikan dan diharapan pula analisis dan desain yang dikembangkan ini mampu menjadi mesin cerdas dengan menggukan sistem fuzzy</em></p><p><strong><em>Kata kunci</em></strong><em> : Fuzzy inferensi, mesin aerator, Sistem cerdas, kualitas air.</em></p>
