Electronic Load Controller based on Dimmer Circuit and Stepper Motor for 5 kW Micro-Hydro Power Plant

This paper presents the results of research on a new schematic generator load controller simulation, namely an electronic load controller based on a dimmer circuit and a stepper motor for a small-scale 5 kW micro-hydro. The load controller is built from a dimmer circuit and a stepper motor with program control using Matlab software, and the PPI 8255 interface device. Using a dimmer circuit built from diac, triac, a variable resistor (pot), and capacitor components. As well as using a 28BYJ-48 stepper motor. Simulation is made to determine the performance of the load controller in controlling the distribution of power to the ballast load when the generator supplies power to consumers less than the full load of the generator. By using the simulation data of 45 variations of the consumer load sample, the result is that there are only 4 samples where the load controller is not working well. For the 4 samples, the generator was loaded beyond its full load tolerance limit (full load tolerance of 5kW ± 5 %). Overall, based on the simulation results, it can be said that the generator load controllers tested in this study have good performance. HIGHLIGHTS Methods and power electronic configurations used in electronic load controllers for micro-hydropower plants from 1980 until now. In the future, the use of low-power micro hydro and pico hydro power plants is also in great demand, especially for rural areas The utilization of micro-hydro in Indonesia, especially low-power micro-hydro, has been utilized by the community in Bulukumba Regency, South Sulawesi Province.

The Organization of Personal Pronouns in Sentence Structure Construction of Makassarese Language

Makassarese language belongs to the Austronesian language family, currently spoken as a mother language by a group of people in South Sulawesi province, eastern Indonesia. This research focuses on personal pronoun organization in the sentence construction of the Makassarese language. The form, position, and function of personal pronouns in the language sentences are explained. It used ‘simak’ (to-observe) method in form of a conversational involved-observation technique including recording and note-taking in collecting data. The data sources were oral data and text data. The oral data were taken from five informants selected purposively. The text data were taken from the folklore script of South Sulawesi written in the Makassarese language. The data were presented descriptively and analyzed by using the distributional method. The findings show two forms of personal pronouns used dominantly in constructing sentences: free personal pronoun and bound personal pronoun (clitic). Position of the free personal pronoun is in front of, in the middle of, and at the end of a sentence. The clitic is in front of and at the end of the verb. In addition, there is also clitic attached at the end of the noun that serves as possessive. The sentence starting with a free personal pronoun forms the pattern of SV (subject-verb) or SVO (subject-verb-object) and the sentence starting with clitic-attached verb forms the pattern of VS (verb-subject) or VSO (verb-subject-object). The basic structure of the Makassarese sentence is VS or VSO. The derivative structure is SV or SVO with other varieties.
