Abstract

Publikasi yang mengungkap tentang peng-gunaan bambu dalam dunia pengobatan masih sedikit sekali bila dibandingkan dengan jenis tanaman lainnya. Penelitian ini bertujuan mengangkat kearifan lokal yang ada di Bali tentang penggunaan bambu tali sebagai obat, mengetahui komponen kimia dasar penyusun bambu tali dan mengetahui kandungan senyawa kimia aktif yang berpotensi sebagai obat. Metode yang digunakan dalam penelitian ini adalah metode wawancara, eksplorasi materi genetik, dan laboratorium (uji proksimat dan GCMS). Hasil penelitian menunjukkan bahwa empat belas respon-den (51,85%) menyatakan bahwa bambu tali berpotensi sebagai obat, berdasarkan lontar usada (kitab pengobatan tradisional Bali) dan sudah mempraktekannya secara langsung terhadap pasien. Akar bambu tali dapat mengobati kencing manis, kencing batu, maag, liver (sakit kuning), hipertensi, ginjal, kanker payudara, limpa, kanker darah, dan batuk. Sedangkan batang (buluh) bambu tali dapat digunakan untuk meremajakan kulit bekas luka, memper-lancar persalinan, mengobati luka, dan mengobati panas dalam. Pengujian prok-simat menunjukkan bahwa bambu tali mengandung protein 2,02% (akar)-4,72% (batang), lemak 6,71% (batang)-7,78% (akar), abu 4,05% (batang)-11,21% (akar), air 8,51% (akar)-8,51% (batang), karbohidrat 70,49% (akar)-76% (batang), pati 12,18% (batang)-13,07% (akar), serat 59,21% (batang)-62,67% (akar) dan antioksidan 29,91 ppm (batang)-42,88 ppm (akar). Pengujian gas chromato-graphy mass spectrometry (GCMS) menggunakan pelarut non polar (hexane) menunjukkan bahwa bambu tali mengan-dung asam lemak, baik asam lemak jenuh (palmitic acid, myristic acid, stearic acid, dan lain-lain) maupun asam lemak tidak jenuh (oleic acid dan lain-lain) serta senyawa lainnya (kurkumin, limonen, dan lain-lain). Ditemukan pula senyawa aromatik seperti toluene, naphthalene, dan 1,3,5-trimethyl benzene.

Abstract

Tebu ireng (Saccharum officinarum L.) merupakan jenis tebu lokal yang memiliki ciri khusus yaitu warna batangnya yang hitam.Secara tradisional tebu ireng dimanfaatkan sebagai obat penyakit diabetes.Selain dapat dimanfaatkan secara tradisional sebagai obat diabetes, diyakini tebu ireng masih banyak menyimpan manfaat lain yang belum banyak diketahui. Studi ini dilakukan untuk mengetahui efektivitas ekstrak tebu ireng sebagai antioksidan dan antimikroba, ditinjau dari beberapa bagian tanamannya. Proses ekstraksi menggunakan metode maserasi dengan pelarut methanol, uji aktivitas antioksidan dilakukan dengan metode DPPH free radical scavenger menggunakan spektrofotometer UV-Vis. Pengujian aktivitas antimikroba dilakukan dengan menggunakan metode difusi agar (Kirby-Bauer disc diffusion method). Hasil studi menunjukkan bahwa tebu ireng memiliki kemampuan sebagai antiokidan.Tingkat kepekatan warna dari tebu ireng berkorelasi dengan aktifitas antiokidannya.Ekstrak dari keseluruhan bagian tanaman tebu ireng efektif untuk menghambat pertumbuhan bakteri Staphylococcus aureus, Salmonella typhimurium, Pseudomonas aeruginosa dan Streptococcus mutans, namun tidak efektif menghambat pertumbuhan jamur Candida albicans.Tebu ireng mengandung pigmen Antosianinserta kaya akan serat pangan .

Abstract

The aim of this research was to determine the effect of time and temperature activation on the quality and chemical structure of bagasse activated charcoal. The study was designed in a completely random design with 3 x 3 factorial, each treatment was 5 times repeated. Bagasse was carbonized in an electrical retort at 400oC for 3.5 hours, then activated at 800oC, 900oC and 1000oC for 30, 60 and 90 minutes at each temperature. The quality of bagasse activated charcoal showed that the yield was 72.57 ~ 91.78%, 5.90 ~ 9.58% moisture content, 39.70 ~ 52.70% volatile matter, 18.40 ~ 25.30% ash content, 26.30 ~ 36.70% fixed carbon, 8.44 ~ 13.40% benzena adsorption, 1036.18 ~ 1474.33 (mg/g) iodium adsorption, 121.91 ~ 124.80 (mg/g) methylene blue adsorption. The surface area of bagasse activated charcoal was 250.45 m2/g. The FTIR analysis indicated that surface of bagasse activated charcoal contained bonding of C-X, S═O, C-N, N-H and C═C. The SEM analysis showed that there were wide pore diameter and plenty of pores. The application of bagasse activated charcoal at two villages reduced the colour, turbidity and iron contents until 65%, 30% manganese contents while hardness of water and pH did not change

Abstract

Saninten (Castanopsis argentea) and tungurut (Castanopsis tungurrut) are plant species belonging to the family Fagaceae, native to the mountainous forest ecosystem within the Gunung Halimun-Salak National Park (GHSNP). These species are currently classified as endangered according to the IUCN Red List due to their significance in providing seeds for consumption and wood for construction materials. This research aims to examine the local community’s knowledge concerning the presence, scarcity, and underlying causes of the decline of both species in the buffer villages of GHSNP. In this study, we employed survey methods and semi-structured interviews conducted with various informants. The data collected were meticulously described and analyzed descriptively. The findings revealed that the local community, in general, holds knowledge about the scarcity of species primarily based on field observations rather than legal or conservation status. Currently, both species are challenging to locate in the buffer villages of the GHSNP. According to the local community’s knowledge, the causes of species scarcity can be categorized into internal and external factors. Internal factors include both species having a slow natural regeneration pattern, difficulties in germination, and vulnerability of seedlings to environmental conditions. Meanwhile, external factors encompass seed and timber exploitation, habitat loss, climate changes, limited knowledge, skills, and understanding of forest plants, and the current perception among locals that C. argentea and C. tungurrut offer limited economic benefits, leading to the gradual neglect of these species’ existence.

Abstract

SUJARWO, W. 2018. Bamboo resources, cultural values, and ex-situ conservation in Bali, Indonesia. Reinwardtia 17 (1): 67–75. — This present study describes the diversity of bamboo resources, based on Bali Botanic Garden’s bamboo collections, and its unusual uses, including complementary information on floristic region, and ex-situ conservation of bamboo resources on the island of Bali, Indonesia. Bamboo resources have played an important role in the economics and culture of rural communities in Bali. Bali Botanic Garden, Indonesian Institute of Sciences (LIPI), started to introduce bamboo species in 1982 and established the ex-situ conservation compartment (2 ha) of bamboo in the same year. Up to now, 52 species in 11 genera collected from mostly the Malesian region (67.44%) and the Eastern Asiatic region (20.93%) have been planted in the bamboo compartment, of which 5.77% bamboo species are woody climbers.

Abstract

An educator has an important role in building national and cultural identity, and ethnopedagogy can play an important role in this because it highlights local wisdom. Ethnopedagogy teaches problem-solving based on local wisdom, so that students' cognitive structures can be activated. This allows students to critically examine the problems that exist in their environment and produce original solutions that refer to the levels found in the local culture which serves as the basis. Critical and creative thinking skills can be instilled by combining problem-solving exercises based on local knowledge with the biology lessons. The method applied in this research is a literature study. The data used is a collection of articles in research journals available in the Google Scholar database and is devoted to learning in Indonesia. The selected literature consists of articles with qualitative and quantitative approaches. There are no limitations on publication year or language usage. The research results show that biology learning cannot be separated from its environment, and incorporating local wisdom in biology learning can make it a fun learning resource. Students can indirectly be trained to care about the surrounding environment, act as biological conservation agents, and preserve the values ​​contained in local wisdom. We conclude that the ethnopedagogical approach in biology learning can be applied because biology learning is natural science-based learning that can be linked to local wisdom. This application can also be expressed in learning media or tools to support the improvement of students’ interest.
