In Minahassa, leilem leaf generally consumed as vegetables. The present study revealed that leilem leaf can inhibit the growth of escherhia coli because of the presence of flavonoid that can demage bacterial cell membranes. This study at characterization of isolated compounds from ethanol extract of leilem leaves (Clerodendrum minahassae Teijsm and Binn). Extraction was done maceration using 70% ethanol with the percentage of rendement was 10,19%. The phytochemical analysis of ethanol extract of leilem leaves showed a positive result of alkoloid, flavonoid, streroid and tanin. The ethyl acetate extract was selected and 2 grams of it was taken to continued to second conventional column chromatography and 5 fractions were obtained. Fraction 2 was choosen and continued to preparative and result 2 isolates. Isolate 2 that showed one spot on tlc with rf 0,66. Was continued for spectrofotometri uv-vis and ftir analysis. The spectrophotometer uv-vis maximum wavalength at 269,0 nm and 333,0 nm. The ftir data indicated the presence of functional O-H, C-H, C=C and C-O which is suspected ad flavonoid.Keywords : Isolation, Characterization, leilem leaf (Clerodendrum minahassae Teijsm and Binn)ABSTRAKDaun leilem (Clerodendrum minahassae Teijsm dan Binn.) dilaporkan yaitu sebagai obat tradisional untuk menyembuhkan beberapa penyakit, seperti sakit perut dan Ascariasis. Daun leilem biasanya dikonsumsi sebagai sayuran oleh masyarakat di Minahasa. Penelitian ini bertujuan untuk mengetahui profil (karakter) senyawa yang diisolasi dari ekstrak etanol daun leilem (Clerodendrum minahassae Teijsm dan Binn.) ekstrak diperoleh dari proses maserasi menggunakan pelarut etanol 70% dengan persen rendamen 10,19%. Hasil uji kandungan kimia ekstrak etanol daun leilem positif mengandung alkaloid, flavonoid, steroid dan tanin. Ekstrak etil astetat dipilih dan diambil 2 gram dilanjutkan untuk dilakukan pemisahan menggunakan komatografi kolom konvensional dan menghasilkan 5 fraksi. Fraksi 3 dipilih dilanjutkan kromatografi kolom konvensional kedua dan didapatkan 5 fraksi. Fraksi 2 dipilih dan dilanjutkan ketahapan kromatgrafi lapis tipis preparatif dan menghasilkan 2 isolat. Isolat 2 yang menunjukkan 1 noda tunggal pada profil KLT dengan niliai Rf 0,66 dilanjutkan untuk dianalisis dengan spektofometri UV-Vis dan FT-IR. Hasil analisis spektrofotometri UV-Vis isolat 2 mempunyai serapan maksimal pada panjang gelombang 269,0 nm dan 333,0 nm-1. Data FT-IR menunjukkan adanya gugus fungsi O-H, C-H, C=C dan C-O yang diduga merupakan senyawa flavonoid. Kata kunci: Isolasi, karakteriksasi, Daun Leilem(Clerodendrum minahassae Teijsm and Binn).

Abstract

This education research aims to investigate the difference learning outcomes of the students taught using cooperative learning model NHT type and conventional type on physics subject of SMP Negeri 2 Poso, find out the different result of students with high beginning ability and those have low ability on physics, and find out whether any or not interaction of learning model and beginning ability of the students learning outcomes on physics. The Population was 130 students of the eighth grade. The research sample consisting of class VIIIA and VIIIB. Design used was factorial 2 x 2. The data were collected through thinking ability and learning achievement test. The data were analyzed by using ANOVA two ways. The result indicates that there was difference of learning outcomes of students taught cooperative learning NHT type from those taught conventional method (p-value < 0,05), different learning outcomes of the students with high beginning ability and those with low beginning ability (p-value < 0,05), no interaction between learning model and beginning ability toward the students learning outcomes (p-value > 0,05) that means the students with high beginning ability will be better their learning outcomes than those with low beginning ability of cooperative learning model NHT type or conventional learning. Keywords: Cooperative Learning Model of NHT Type, Beginning Ability, and Learning Outcomes

Abstract

The life of the religious community cannot be separated from religious activities in this case the Covid-19 pandemic in religious activities did not escape social changes in religious communities, especially in the City of Parepare. Thus, in this study trying to analyze the conflicts and power relations that occur in the community with various religious activities from various existing religions. This research is a qualitative method with a data approach in the form of narratives, stories, expressions from informants. Meanwhile, the type of research used is a case study. Informants in the research based on the needs in this study include religious leaders, government officials, the community and discourses that narrate about conflicts and power relations.Research shows that during the COVID-19 pandemic, the ideal of worshiping in congregation has changed drastically. Routine worship is no longer carried out in mosques, churches, or monasteries but is carried out in their respective homes. The people involved are also very limited, in this case it only involves family members who are at home. Based on knowledge and power, it is also closely related to the power relations between the government, religious leaders, and the community. The condition of the COVID-19 pandemic requires an open and “flexible” attitude for religious people to combine two different interests. When religious teachings command to worship communally in the face of various government regulations, many things should be compromised.
