Abstract

A DC generator is a dynamic electrical system that converts mechanical energy into electrical energy. A free and separate excitation type DC generator is a generator whose field winding can be connected to a DC source. The power source is independent of the engine. The DC voltage field coils mounted on the form of resistance Rf will generate currents If and cause flux on both poles. The induced voltage will be generated in the generator. The load characteristics of a DC generator show the relationship between the terminal voltage Vt and the field current If when the generator is loaded. When the generator is loaded, a load current will flow IL. In this study, the calculation method used is fuzzy logic, Mamdani. The results obtained when loaded with a field current of 1.2 Amp measured a clamping voltage of 123.5 Volt with a load of 100 watts. When 1.1 Amp lowered the current, the clamping voltage decreased to 120.6 Volt with a load of 100 watts. In comparison, the results of fuzzy logic in 1.2 Amp field current-induced voltage is 128 Volts with a load of 100 watts, so the average percentage difference is 6.74%. To calculate efficiency at a field current of 1.2 Amp load of 100 watts, the resulting efficiency is 44.22%, the greater the load, the smaller the efficiency value. While the efficiency results generated using fuzzy logic are 43.9% with a field current of 1.2 Amp and a load of 100 watts, the average value of the difference is 1.17%.

Abstract

Seiring dengan perkembangan zaman yang semakin pesat, kebutuhan akan efektifitas dan efisiensi sangat diutamanakan dalam berbagai bidang. Hal tersebut telah mendorong manusia untuk berkreasi dan berinovasi dalam bidang teknologi untuk menciptakan suatu alat yang lebih efektif dan efisien. Jika kita perhatikan di banyak mall yang mengunakan pintu otomatis yang terbuka sendiri tanpa harus membuka pintu secara manual, penelitian ini akan membahas tentang penerapan pintu otomatis di rumah rumah seperti layaknya di mall atau pun tempat umum lainya. Penelitian ini bertujuan untuk membuat pintu otomatis rumah berupa prototype pintu rumah otomatis sebagai bentuk dari perkembangan teknologi dalam memberikan kenyamanan danam membuka pintu yang efektif dan efisien. Dalam kehidupan sehari-hari, kegiatan didalam dan diluar ruangan selalu dilakukan berulang selama adanya aktifitas dirumah, maka segala aktifitas tersebut tidak lepas dari keberadaan suatu pintu yaitu membuka dan menutup pintu secara berulang-ulang kali dengan cara menarik ataupun mendorong pintu. Namun hal berbeda ketika pintuk dapat membuka dan menutup sendiri secara otomatis.

Abstract

The low accessibility of handling and services for persons with disabilities in Pekanbaru City, Riau Province, will certainly be an obstacle to the fulfillment and protection of rights for persons with disabilities. These barriers will have an impact on the development and rights of life for these marginalized people. Therefore, it is necessary to conduct an assessment to map the general situation and optimize the fulfillment of the rights of persons with disabilities. In this case, the researcher appointed Pekanbaru City as the focus of research. The stages of the research method are literature study, interviews, field observations, focus group discussions and data analysis. The results of this study will be used as a basis for developing policies that are inclusive of persons with disabilities so that they have equal opportunities before the State to enjoy social, economic, political, civil and cultural rights. The purpose of the study was to analyze the perception of the disabled community towards disability policies and facilities in the city of Pekanbaru and to analyze the preferences of the disabled community towards policies and facilities. The results show that the highest need for Infrastructure is 93%. In the Health sector, Hospital Needs with a percentage of 95.4%, Business Capital Requirements really help the economy of families with disabilities, namely the largest response of 94.70%, the Education Sector for special knowledge needs for disabilities the largest 84.3%, and the religious field needs lecturers and preachers disability-friendly 78.9%.
