Abstract

Penelitian ini bertujuan untuk menganalisa pengaruh dari penggunaan beberapa tepung sebagai alternatif stabilizer pada es krim buah naga terhadap mutu fisik dan organoleptik. Tepung yang digunakan adalah tepung maizena (jagung), tepung tapioka(singkong), tepung jamur tiram serta CMC sebagai kontrol. Penelitian dilakukan dalam dua tahap yaitu 1) pembuatan es krim buah naga dengan penambahan stabilizer alami berupa tepung maizena(jagung), tepung tapioka(singkong), tepung jamur tiram pada berbagai tingkat konsentrasi yaitu sebesar 0,1, 0,3 dan 0,5%b/v dan 2) penentuan perlakuan terbaik dari masing-masing penggunaan penstabil alami. Berdasarkan hasil penelitian diketahui es krim buah naga merah yang menggunakan jenis stabilizer alami tepung tapioka(singkong) dan tepung jamur tiram. Perlakuan tersebut secara data penelitian mampu mendekati CMC (Carboxyl Methyl Cellulose) sebagai penstabil es krim. Pada perlakuan tepung tapioka(singkong)  konsentrasi sebesar 0,5% diperoleh overrun sebesar 31,67%, daya leleh sebesar 1266 detik/10 gram atau sebesar 21,1 menit/10 gram, skor organoleptik tekstur sebesar 3,6 (agak lembut mengarah ke lembut), dan skor organoleptik rasa sebesar 3,3 (agak suka). Pada perlakuan tepung jamur tiram konsentrasi sebesar 0,5% diperoleh overrun sebesar 52,60 %, daya leleh sebesar 1122 detik/10 gram atau sebesar 18,7 menit/10 gram, skor organoleptik tekstur sebesar 3,5 (agak lembut mengarah ke lembut), dan skor organoleptik rasa sebesar 3,3 (agak suka) pada konsentrasi sebesar 0,1%.

Abstract

Education is a conscious effort made to prepare human resources to be able to participate actively in society. Good education is expected to give birth to a superior generation that can continue the development and progress of a nation. Quality education is determined, among other things, by the presence of quality teachers, namely teachers who can carry out their responsibilities professionally. Professional teachers have at least four competencies, namely pedagogic, personality, social and professional competencies. Developing teacher professionalism is a continuous effort made to ensure the quality of education and learning in schools. Teacher professionalism development takes place at three levels, namely personal, institutional and government. The implementation of teacher professionalism development is still problematic in several regions, especially considering the low quality of education. The results of international comparative studies such as TIMSS and PISA place Indonesia in the lowest position. This research aims to find out how teacher professionalism is developed in North Hulu Sungai Regency. This research uses a case study strategy at SDN Rantau Karau Tengah and SDN Rantau Karau Hilir. The results of the research show that, at both SDN Rantau Karau Tengah and SDN Rantau Karau Hilir, the majority of teachers have a bachelor's education certificate, which is the minimum requirement as a teacher, and the majority of teachers have a certificate as a professional teacher. The development of teacher professionalism in North Hulu Sungai Regency occurs at all levels, namely the personal, institutional and government levels. In terms of participation in teacher professional development programs, the two SDNs differ quite significantly. Teachers at SDN Rantau Karau Hilir generally have participated in training carried out by the government, while teachers at SDN Rantau Karau Tengah are less involved in scientific activities, such as seminars and the like, are diligent in participating in teacher achievement competitions, and feel that the District Government provides assistance. towards increasing their professionalism. Meanwhile, teachers at SDN Rantau Karau Tengah are not always involved in scientific activities, rarely take part in achievement teacher competitions, and feel that the District Government does not contribute to increasing their professionalism.
