The era of globalization demands education institution to be adaptive, creative, and innovative, including Islamic boarding schools as the institutions of Islamic education which become the national cultural heritage. One of the innovative programs is capacity building as a series of strategies aimed at increasing efficiency, effectiveness, and responsiveness of performance. This study was directed to explore capacity building implementation at Darul Amin Islamic modern boarding school Southeast Aceh. A qualitative research approach with a case study as the research strategy was implemented. The results of the study showed that capacity building focused on three dimensions, namely (1) human resource development; (2) organizational strengthening, and (3) institutional reform. The principle of Darul Amin capacity building contained the elements of participation, repetition, relevance, transfer, and feedback. In the process of capacity building, there were four stages, namely (1) pre-formal stage (pilot education organization); (2) formal stage (potential education organization); (3) transitional stage (national standard education organization); and (4) autonomous stage (international standard education organization). Towards the existence of the institution, Darul Amin also made various efforts at various levels, namely the system level, organizational level, and individual level.
Abstract. Arbiastutie Y, Diba F, Masriani. 2021. Short Communication: Ethnobotanical and ecological studies of medicinal plants in a mangrove forest in Mempawah District, West Kalimantan, Indonesia. Biodiversitas 22: 3164-3170. The mangrove forest Polaria Tanjung Pagar in Mendalok Village, Mempawah District, West Kalimantan, Indonesia, is a mangrove forest maintained by the local community. Currently, this mangrove forest has become one of the tourist attractions, not only visited by local and national, but also foreign tourists. This study aims to identify plants in Polaria Tanjung Pagar mangrove forest Kalimantan with the potential for medicinal uses. The research used a survey method in the mangrove forest by conducting an inventory of the medicinal plants found in the mangrove forest. Observations were made using a transect line with the total area understudy of 0.012 ha and sampling intensity of 0.4%. The investigation was based on cross-checking the traditional use of medicinal plants by the surrounding communities and the scientific literature. The results showed 13 types of medicinal plants (including tree and understorey plants) from 6 different families, i.e., Acrostichum aureum, Aegiceras corniculatum, Avicennia marina, Avicennia alba, Bruguiera parviflora, Bruguiera gymnorrhiza, Bruguiera cylindrica, Ceriops decandra, Rhizophora apiculata, Rhizophora stylosa, Rhizophora mucronata, Xylocarpus moluccensis, and Sonneratia caseolaris. The community structure of the mangrove forest had moderate diversity for tree species and low diversity for understorey plant species, with an H' valued at 2.39 and 0.25, respectively.
Cytotoxic activities of extracts of Pycnarrhena cauliflora leaves, stems and roots on some human cancer cells have been known. However, the cytotoxicity of stem of Pycnarrhena cauliflora on human breast cancer cell line T47D through an apoptosis induction has not been proven yet. This study was an effort in understanding the cytotoxic activity of stem of Pycnarrhena cauliflora through apoptosis induction. The crude ethanol extract was partitioned between n-hexane and dichloromethane at pH 3, 7 and 9, which was subsequently tested for their cytotoxic activity against human breast cancer cell line T47D by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT). Flow cytometric analysis with Annexin V-FLUOS/ propidium iodide (PI) double staining was used for apoptosis analysis. The dichloromethane fraction at pH 7 was considered the most potent with an IC 50 value of 59.30 µg/mL and induced apoptosis on the T47D cell line. The result indicated the potential of dichloromethane fraction of the stem of P.cauliflora as a source of bioactive compounds and provided a basis of further studies to isolate a new anticancer compound.
The people in Rasau Jaya Umum village Kubu Raya regency have used plants as ingredient food that has been inherited from generation to generation for daily cooking or to make the typical food. The typical food in Rasau Jaya Umum village like Rengginang, crackers, and salted fish. The purpose of research to collect data of plants used as food additives by people in Rasau Jaya Umum village. The respondents were chosen through snowball sampling technique and then given a series of questions using observation sheet. The head in Rasau Jaya Umum village is chosen as the main respondent then proceeded to the traders and home industry owners who produce the typical food. The results showed that there are 18 species of 15 plant families used as natural additives, namely Liliaceae, Zingiberaceae, Amaranthaceae, Oxalidaceae, Rutaceae, Arecaceae, Poaceae, Gnetaceae, Malvaceae, Cactaceae, Pandanaceae, Piperaceae, Polygonaceae, Anacardiaceae, and Myrtaceae.Keywords: plants, food additives, Rasau Jaya Umum village
Penelitian yang dilakukan ini bertujuan untuk mengembangkan Lembar Kerja Peserta Didik berbasis Predict-Observe-Explain pada sub materi pergeseran kesetimbangan dan menentukan kelayakan LKPD tersebut berdasarkan penilaian para ahli dan respon peserta didik. Bentuk penelitian ini adalah Research and Development (RD) dengan menggunakan model ADDIE yang telah dibatasi menjadi model ADD, yaitu Analysis, Design, dan Develop tanpa melakukan tahap Implement dan Evaluate. Subjek penelitian adalah LKPD dan subjek responden adalah peserta didik kelas XI IPA SMA Negeri 2 Sungai Raya. Alat pengumpul data dalam penelitian ini adalah lembar validasi kelayakan LKPD dan angket respon peserta didik. Hasil validasi pada penilaian kelayakan materi, bahasa, dan penyajian dianalisis dengan rumus CVI memperoleh nilai rata-rata sebesar 1 yang menunjukkan bahwa LKPD berbasis Predict-Observe-Explain berada dalam kategori validitas sangat tinggi. Hasil uji angket respon peserta didik diperoleh rata-rata persentase sebesar 76.03% yang menunjukkan bahwa respon peserta didik terhadap LKPD berada dalam kriteria baik. Berdasarkan hasil yang diperoleh dapat disimpulkan bahwa LKPD berbasis Predict-Observe-Explain sangat layak dan baik digunakan sebagai media pembelajaran untuk mendukung proses pembelajaran kimia pada sub materi pergeseran kesetimbangan.
Dillenia suffruticosa is one of the tropical medicinal plants that has been used traditionally for treating several tropical diseases. However, phytochemical and pharmacological investigations of D. suffruticosa wood bark have not been well-investigated. This research aimed to investigate the correlation between antioxidant properties and total phenolic content of phenolics rich extract and fractions from D. suffruticosa wood bark. The phytochemical investigation revealed the existence of phenolics and alkaloids in methanolic crude wood bark extract and all fractions. Meanwhile, the presence of flavonoids was shown in chloroform and methanol fractions. The highest total phenolic content was demonstrated by methanol fraction with 254.34 ± 16.86 mg GAE/g extract. Meanwhile, the highest total flavonoid content was interestingly displayed in chloroform fraction with 15.33 ± 0.26 mg RE/g extract. The crude extract and methanol fraction had a profound antioxidant activity with IC 50 values of less than 15.63 ppm and 8.83 ppm, respectively. A strong correlation was shown between the antioxidant activity and total phenolic contents through correlation analysis. Thus, the D. suffruticosa wood bark could be considered a potential natural source of antioxidants.
