Abstract

Low understanding among teachers regarding the concepts and benefits of Classroom Action Research (CAR) as a means of professional development is one of the main problems at SD Negeri 2 Labuan. Most teachers are not yet accustomed to systematically reflecting on their teaching practices thru classroom-based research. This resulted in very limited teacher participation in CAR activities, and the learning innovations that were supposed to emerge from this process were also hindered. To address this, the Faculty of Education and Teacher Training at Tadulako University conducted a Community Service (PkM) activity to improve teacher competence thru training and the implementation of Classroom Action Research. This activity included training, mentoring in preparing CAR as well as reflection and evaluation. The evaluation results show an 84% increase in teachers' understanding of CAR. Full support from the school and active participation from the teachers also contributed positively to the success of this activity.

Abstract

Wuluh star fruit plant (Averrhoa bilimbi L.) was a traditional medicinal plant that was rarely utilized as a natural medicine and contained many secondary metabolite compounds, one of which was tannin. This study aimed to determine the type of tannin and the amount of tannin content in belimbing wuluh leaves. Wuluh star fruit leaf powder was extracted by the maceration method using 96 % ethanol solvent, and then the filtrate was concentrated by rotary evaporator. Identification of tannin types in the extract was performed using CH3COOH 10 %, (Pb(CH3COO)2) 10 %, HCl, FeCl3, and KBr. For analysis of tannin content, Folin-Ciocalteau reagent and 15 % Na2CO3 solution were added, and then analyzed using UV-Vis spectrophotometry at a wavelength of 765 nm. The results of the identification of tannin types showed that belimbing wuluh leaves included condensed tannins, and the results of the analysis showed that the tannin content was 7.282 mg/g extract.

Abstract

Desa Tanah Harapan Kecamatan Palolo Kabupaten Sigi merupakan salah satu daerah yang anggota masyarakatnya umumnya adalah petani persawahan (petani padi) dan buruh tani. Luas lahan persawahan yang ada di kecamatan Palolo mencapai 2951 ha, yang tersebar pada 11 desa. Desa Tanah Harapan luas lahan persawahannya 766 ha dengan produksi gabah kering giling 1225 ton pertahun, kebun tanaman keras berupa kakao dan kelapa luasnya sekitar 1002 Ha. Padi/gabah yang masuk dalam penggilingan padi di desa Tanah Harapan dan desa sekitarnya rata-rata sebesar 12,8 ton perhari. Pada penggilingan padi akan di hasilkan sekam sekitar   20-30%   sekam   padi. Berdasarkan hal tersebut maka setiap harinya akan dihasilkan limbah sekam padi 2,6-3,8 ton. Masalah yang dihadapi masyarakat adalah belum adanya teknologi pemanfaatan limbah sekam padi tersebut ke arah yang bernilai ekonomi tinggi agar dapat memberi nilai tambah pada masyarakat sehingga dapat meningkatkan tarap hidup masyarakat di desa Tanah Harapan dan desa sekitarnya. Program pengabdian ini bertujuan untuk meningkatkan pengetahuan dan keterampilan petani dalam mendesain teknologi pembuatan arang briket dan asap cair dari sekam padi serta arang sekam padi sebagai salah satu bahan penjernih air dan teknologi asap cair sebagai salah satu bahan pengawet alami. Metode yang digunakan adalah metode penyuluhan dan pelatihan serta demplot aplikasi yang dilakukan dengan pendekatan partisipatif. Kegiatan pelatihan dan workshop dilakukan dalam upaya meningkatkan pengetahuan sedang pelatihan dan demplot dilakukan dalam upaya mempercepat proses alih teknologi kepada masyarakat. Hasil akhir dari program ini adalah meningkatnya pengetahuan petani serta tersedianya paket teknologi pembuatan arang briket dari sekam padi dan teknologi pembuatan asap cair dari sekam padi sehingga kelompok sasaran tersebut dapat mandiri dalam menjalankan kegiatan usaha pemanfaatan limbah sekam padi menggunakan rakitan teknologi yang telah dipraktekkan tersebut secara berkelanjutan.
