Abstract

Herbal tea is one of the functional drinks, which is consumed for the purpose of preventing or treating disease. The number of side effects that arise from the consumption of drugs made from synthetic or chemical materials has led to a tendency for people to return to consuming herbal plants as a solution to health problems. The purpose of this study is to make tea from the roots of tampala (Spatholobus littoralis Hassk) and to test the physical and chemical properties, organoleptic examination and determination of antioxidant activity. Testing of physical and chemical properties including water content, ash content and pH of the preparation, organoleptic examination including taste and odor and color of the brewed solution and determination of antioxidant activity was carried out using the DPPH method (2,2-diphenyl-1-picrylhydrazil). The results of the physicochemical test of tampala tea showed that a pH of 6.8, water content of 7.63%, ash content of 7.7%. On organoleptic examination, the tea using the brewed water showed a slightly sour taste, a characteristic wood smell and a brownish yellow color. Based on the physical and chemical character of the tampala herbal tea test results, it meets the requirements of SNI No. 3836 of the 2013 National Standardization Agency, while the antioxidant test results of the tampala herbal tea was obtained an IC50 value (Inhibition Concentration 50) of 89.63 ppm, included in the category of strong antioxidant potential, because it is in the category of strong antioxidant potential. in the range of 50-100 ppm.

Abstract

Artikel ini menyajikan hasil pengabdian pada masayarakat (PKM) pada masyarakat nelayan Kecamatan Sukadana Kayong Utara Kalimantan Barat dalam usaha penyelamatan dan pelestarian sumberdaya hayati hutan mangrove. Tujuan PKM secara umum untuk mengkaji persepsi dan partisipasi masyarakat nelayan Kecamatan Sukadana Kayong Utara dalam pemanfaatan, pencegahan kerusakan hutan mangrove, serta memberikan penyuluhan terkait penyelamatan hutan mangrove dalam rangka pelestarian sumberdaya hayati pesisir. Metode PKM dilakukan melalui penyuluhan. Untuk mengetahui pengetahuan masyarakat terkait penyelamatan sumberdaya hayati mangrove, sebelum dan sesudah penyuluhan dilakukan evaluasi dalam bentuk  pengisian kuisioner terhadap peserta PKM. Jumlah peserta PKM yang hadir berjumlah 68 peserta yang merupakan perwakilan dari kelompok nelayan, pemuda dan kelompok desa wisata (POKDARWIS) se Kecamatan Sukadana.  Berdasarkan hasil kuisioner sebelum pemberian penyuluhan menunjukkan bahwa sebagian besar penduduk (53 %) memiliki pengetahuan kategori cukup baik tentang manfaat, kerusakan akibat pemanfaatan, dan perlunya pencegahan kerusakan hutan mangrove. Pentingnya manfaat hutan mangrove, kerusakan akibat pemanfaatan, dan perlunya pencegahan kerusakan; secara umum belum dipersepsikan secara positip oleh penduduk setempat.  Meskipun demikian partisipasi mereka dalam pemanfaatan dan pencegahan kerusakan hutan mangrove; sebagian besar termasuk kategori cukup baik. Tingkat partisipasi penduduk dalam pengelolaan hutan mangrove, sangat dipengaruhi oleh frekuensi kontak dengan media masa, intensitas pelatihan konservasi yang diikuti  dan kontribusi hutan mangrove terhadap ekonomi keluarga. Kebijakan pemerintah daerah untuk pengelolalaan hutan mangrove, ditanggapi secara negatip oleh masyarakat setempat. Hal itu disebabkan oleh belum adanya usaha pengelolaan hutan mangrove secara jelas dan tegas. Berdasar temuan tersebut maka aspek-aspek sosial ekonomi masyarakat setempat, perlu digunakan sebagai salah satu dasar pengelolaan hutan mangroveKata kunci: Mangrove, Pelestarian, Sumberdaya hayati, Masyarakat Nelayan, Sukadana

Abstract

Family Medicinal Plants or can be abbreviated as TOGA is a type of plant that is cultivated in the yard of the house. Cultivated plants not only provide family health but also provide the beauty of the yard. The development of TOGA in Cipta Karya Village which is a tourist village has been socialized but the management and utilization of TOGA has not run optimally. The introduction of medicinal plant species and their use is still largely unknown to the public. The purpose of this community service activity program is to increase the income of family members through a program to utilize family medicinal plants as family herbs. The activities carried out were socialization and demonstrations about the potential and utilization of medicinal plants in the community in Cipta Karya village. Socialization about TOGA in addition to supporting health, also provides environmental beauty, plant conservation and can provide family welfare. The results of this activity indicate an increase in participants' knowledge of plant species that have potential and have medicinal properties and how to make TOGA so that there is an aesthetic and beautiful environment and can improve the family's economyKey word: Family Medicinal Plants (TOGA); Health; Family Economy

Abstract

Rhizophora apiculata is a mangrove species that lives in coastal areas. Differences in zoning will affect the growth of mangroves both morphologically and anatomically. This study aims to determine the morphological and anatomical characteristics of R. apiculata leaves in different zones. The research method used is descriptive method. Zone A is the zone near the sea water and zone B is the zone away from the water. Morphological observations were made directly, while anatomical observations were made through making preparations with the embedding method. Observations of leaf area parameters of R. apiculata in zone A showed a larger leaf area (83.11 ± 6.07cm2) compared to zone B (63.95 ± 8.61cm2). R. apiculata leaves in zone B had a higher number of stomata (24.42±5.60mm2) and stomatal density (124.43±28.43 cells/mm2) than zone A, which had a higher number of stomata (17.44±5.99mm2) and stomatal density (88.87±30.44 cells/mm2). Mesophyll tissue thickness parameters showed no significant difference between zone A and zone B. Parameters of salt glands showed significant differences between zone A and zone B. The results of the study, it can be concluded that differences in mangrove zones provide different responses and adaptations to the morphology and anatomy of R. apiculata leaves.
