Abstract

This study is to describe the form of speech acts, the function of speech acts, and the effects of perlocutionary speech acts that appear in the oration activity of revoking the Omnibus Law Job Creation Act in Samarinda. This study uses the referential method, which is a method where the determinant is in the form of a reference or reality designated by language. The next method is the pragmatic matching method, the determining method is the speech partner. The results of the analysis of locutionary, illocutionary, and perlocutionary speech acts in the oration of the revoking of the Omnibus Law Job Creation Act in Samarinda showed that the speech contained a locutionary speech act in the form of a statement. Locutionary speech acts also found illocutionary speech acts with the types of assertive illocutionary, directive illocutionary, expressive illocutionary, and commissive illocutionary speech acts. The illocutionary speech act is firm with the function of blaming and complaining. Directive illocutionary speech acts with a commanding function. Expressive illocutionary speech acts with the function of thanking and blaming. Commissive illocutionary speech acts with credit function. In this study also found perlocutionary speech acts with the function of influencing other people or certain parties to do something as expected by the speaker, so that there is an effect on the interlocutor. The effect of the perlocutionary speech act that occurs can be seen from the response of the interlocutor by paying attention to the speech context.

Abstract

Penelitian ini bertujuan untuk mengetahui pemanfaatan tulang ayam sebagai adsorben methylene blue. Limbah tulang ayam banyak ditemukan di lingkungan masyarakat namun jarang dimanfaatkan atau bahkan tidak dimanfaatkan. Hal ini tentunya menimbulkan masalah lingkungan akibat sisa tulang yang tidak memiliki nilai ekonomi. Zat warna methylene blue merupakan pewarna sintetik yang dapat membahayakan makhluk hidup. Oleh karena itu, perlu dilakukan upaya adsorbsi zat warna dari lingkungan makhluk hidup, dengan menggunakan adsorben dari limbah tulang ayam. Penelitian ini menggunakan metode eksperimen, dengan cara mengukur keadaan awal jenis sampel sampai dengan mengukur keadaan setelah diberi perlakuan. Hasil penelitian menunjukkan kadar zat yang teradsorbsi maksimum berada pada kecepatan pengadukan 150 rpm pada serbuk dan abu tulang ayam sebesar 72,947% dan 64,183%. Pada konsentrasi optimum menunjukkan kadar zat yang teradsorbsi berada pada konsentrasi 125 ppm pada serbuk dan abu tulang ayam sebesar 58,710% dan 66,167%. Sedangkan pada pH optimum menunjukkan kadar zat yang teradsorbsi pada serbuk adalah pH 9 sebesar 78,831% dan pada abu adalah pH 7 sebesar 67,997%. Dapat simpulkan bahwa limbah tulang ayam dapat mengadsorbsi zat warna methylene blue.

Abstract

The purpose of this study was to ascertain the impact of repeated heating of coconut oil on the value of viscosity, density (mass density), surface tension, and the coefficient of temperature reduction rate (Newton cooling constant). The coconut oil sample used was the result of my own production. The heating repetition was carried out at most five times with a peak temperature of 90oC. The physics quantities were respectively determined by the methods of the falling ball, the directly measuring the mass and volume with the measuring cylinder, the raising fluid in a capillary tube, and the Newton cooling.From this study, it was found that there was an effect of repeated heating of coconut oil on the value of viscosity, mass density, surface tension, and the Newton cooling constant. This effect is indicated by the presence of a functional relationship between the heating test and the value of the four physical quantities. The relationship between heating repetition and viscosity is a quadratic function, the relationship between heating repetition and mass density is a linear function, the relationship between heating repetition and surface tension is a quadratic function, and the relationship between heating repetition and Newton cooling constant is a quartic function. The four functional relationships are empirical equations that state the laws of nature in a certain heating range and can be used as material for further studies to reveal the physical mechanisms that build them, including determining the general equations that unite them.
