Abstract

Granules extract of clime fruit (Citrus aurantifolia L.) is a biolarvasida in eradicating Aedes aegypti mosquito larvae L. Granules extract of lime fruit (Citrus aurantifolia L.) can kill mosquito larvae because its content of limonoida, tannin, flavonoid, and volatile oil. The compound is lethal to the larvae which will enter the body of the larvae of the Aedes aegypti L. mosquito which disrupts the systems in its body. The purpose of this article is to determine the safety of lime fruit (Citrus aurantifolia L.) extract granules on non-target animals, namely tadpoles. Tadpole has the same habitat with mosquito larvae so it is done safety test of citrus fruit extract granule (Citrus aurantifolia L.). Tadpole is a larval phase in Amphibi that continues to experience morphological development in water. The initial phase of tadpoles growth is a phase of adaptation to its habitat. Individuals who can not adapt well will experience a faster death. The research method used is laboratory experimental. The analysis used is ANOVA. The independent variables in this study were the variety of granules extract concentration of citrus fruit (Citrus aurantifolia L.). Tadpole mortality became the dependent variable in this study. Tadpole mortality is characterized by tadpoles collapsing at the time of administration of granules. The results showed that the lime extract granules (Citrus aurantifolia L.) proved safe.

Abstract

Physics is one of the lessons that the students do not like the most, so it results in students learning activities which then will lead to the low interest of the learning itself. The result of the observation during the learning process in the 3rd grade students of science I showed that there were only six students who actively raised their hands and asked some questions, while 65% of them followed the class regularly. The questionnaires confirmed that only 45% of them who liked physics, so it resulted in the result of their study on physics that was low, and only 45% of them who finished studying physics. Therefore, this research was conducted by applying ‘guided inquiry’ model on physics learning in the 3rd grade students of science I at the first semester of 2013/2014. The indicators used to measure the effectivity of the learning process were students learning activities, students learning goals, and students perception on the learning itself.The result in cycle 1 showed that the average of the students activities reached 65%, the students learning goals reached 65%. It was related to the number of the students who liked physics turned into 65%. Moreover, cycle 2 showed that there was the increasing number of the students learning activities that had reached 75%, the students learning goals had also reached 75%, and those who liked physics had reached 70%. Based on the result noted above, it can be drawn the conclusion that the implementation of ‘guided inquiry’ model can effectively improve the students learning activities and their learning goals as the result of the increasing number of the students who like physics.

Abstract

Meru Betiri National park has a region part, it’s reference zone and rehabilitation zone. Referensi zone is a conservation area that have to protect from damage by human interference to protect flora, fauna and other environmental component for importance of next generation. Rehabilitation zone was damaged without original vegetation and be a seasonal land farm. Termites is a important part of insect in material recycling of plant trhough disintegration process. The aim of the research are to knowing types of termites and to knowing the different of termites diversity in referensi zone and rehabilitation zone Meru Betiri National Park. Research methods by used direct sampling. The result of research has get 2 species founded, that’s Macrotermes gilvus Hagen (mayor), Macrotermes gilvus Hagen (minor) and Nasutitermes metangensis with totally 194 individual. Index of species diversity (H’) in the reference zone = 0, it's caused there are only one species founded and index of species diversity (H’) in rehabilitation zone = 1,036. It can be concluded that diversity of species on both has a different level diversity although same on low diversity.

Abstract

Tujuan penelitian ini adalah mengkaji keterampilan mahasiswa secara kolaboratif menyelesaikan saat diberikan permasalahan pembelajaran dan disebut Collaborative Problem Solving (CPS). Metode yang digunakan untuk mengkaji keterampilan CPS mahasiswa menggunakan evaluasi countenance stake. Analisis skema observation dan judgement menggunakan pendekatan Model Rasch. Metode pengumpulan data secara observasi untuk keterampilan CPS meliputi Cognitive Skills dan Social Skills, data lembar hasil penyelesaian masalah (LO), dan Kuesioner pengalaman belajar mahasiswa (CEQ). Hasil analisis congruence dan contigency dengan Model Rasch menunjukkan bahwa mahasiswa memiliki cognitive skills yang cukup baik, namun social skills mahasiswa tidak dimiliki secara maksimal. Sehingga tingkat keberhasilan penyelesaian masalah masih kurang dari standar karena berbagai potensi ide solusi seluruh anggota tidak terakomodir secara baik. Selain itu, temuan penelitian memberikan rekomendaasi perlunya kajian lebih lanjut terkait keterempilan bernalar dan berpikir kreatif mahasiswa dalam menyelesaikan masalah agar diketahui kreativitas berpikir dan cara bernalar seperti apa yang digunakan mahasiswa untuk mengambil keputusan atau solusi permasalahan.
