ABSTRACTIndonesia has about 25000-30000 species of plants and inhabited by 300-700 ethnic.The ethnic groups in Indonesia uses of plants for variety of purposes, one of them asmedicine. The uses of plants as medicine passed on orally and thus susceptibledegraded. Ethnomedicine studies is can be use to documentation of medicinal plantsby ethnics through scientifically research methods. This article aims to explain theethnomedicine studies in Indonesia and its approach research methods. This paper isbased on literature offline and online media. Ethnomedicine is perception andconception of ethnic/local communities to health concept by local ethnics.Ethnomedicine studies in Indonesia was initiated by Rumphius on century 19th whichdocumention of uses of plant by local etnich Ambon. Those are documented in thebooks with entitle Amboinense Herbarium. Heyne in 1927 recorded 1040 spesieswhich uses by local ethnic Indonesia, that are documented in the book entitled Denuttige planten van Nederlandsch. Research continues to increased, but mainconcentrated in Java and Bali, while the other islands is few. Ethnomedicine studiescan be approaches do public surveys and market surveys.

Abstract

An experiment to study the effect of soft fraction derived from Saccharomyces cerevisiae (Hansen) to elicit ajmalicine production by Catharanthus roseus (L.) G. Don. callus cultures has been conducted. Callus were induced from leaf segment and grew on Zenk medium supplemented with 2,5 x l0M NAA dan 10 M BAP respectively. Callus on the third subculture level were elicited with soft fraction derived from S. cerevisiae. The following concentrations of elicitor tested were 0, 0,5, 1,0 and 2,5 % (g/v), and the harvesting times were 0, 18, 36 and 72 hour respectively. Influence of elicitor to production of ajmalicine by the callus were analyzed qualitatively and quantitatively by using high performance liquid chromatography (HPLC). A significant increasing of ajmalicine content in the callus (303,475 ± 5,602 ug/gDW) was achieved by addition of elicitor of 0,5 % (g/v) after 36 hour. This study showed a significant increase of ajmalicine production in C. roseus callus cultures after being challenged with elicitor derived from S. cerevisiae i.e. 69,334%.

Abstract

Kaempferia galanga (KG) atau kencur telah lama digunakan masyarakat Asia termasuk Indonesia sebagai obat tradisional dan bumbu masak. Informasi yang konfrehensif botani, metabolit sekunder dan bioaktivitas KG sangat penting untuk pengembangannya sebagai obat tradisional sehingga dapat meminimalisasi efek sampingnya. Penulisan artikel ini didasarkan studi literatur yang diperoleh secara on line maupun off line berupa buku, jurnal maupun hasil penelitian lainnya. KG merupakan tanaman herba aromatis dengan daun biasanya 2-3(-5) dengan seludang 1,5-5 cm, daun sering horizontal dan menutupi permukaaan tanah. Ethyl-trans-p-methoxy cinnamate dan trans-ethyl cinnamate merupakan senyawa utama yang sangat penting pada KG dan merupakan komponen yang memiliki sifat pharmakologi, oleh karena itu penting dilakukan pemilihan aksesi dengan kandungan senyawa bioaktif yang tinggi. Secara etnobotani KG digunakan sebagai obat ekspektorat, karminatif, obat batuk, rematik, dan anti kanker, kolera, vasorelaksasi, anti mikroba, antioksidan, anti alergi penyembuhan luka. Walaupun secara etnobotani banyak manfaat dari KF, namun bioaktivitasnya membuktikan aktivitas KG sebagai anti kanker, anti oksidan, anti inflamasi, analgesik dan anti bakteri

Abstract

Nursery is a places for buying, selling transactions and plants care in the urban. This study aims to reveal the diversity of plants that are traded in the Kranggan nursery, Bekasi, West Java. This research was conducted by surveying and interviewing nursery owners and managers to find out the types of plants being traded. Reponden was determined by purvosif sampling with criteria namely having a nursery of at least 100 m2 or having worked at the nursery for at least 2 years. The data obtained was analyzed descriptively statistically. Plants that are traded in Kranggan nursery vary greatly between one trader and another, namely between 93-140 species of plants. A total of a total of 197 plants were traded in the Kranggan nursery which were included in 158 genera and 76 families. When viewed from the habitus, most of the traded plants (86 species) are herbs, followed by trees (69 species), shrubs (36 species) and lianas (6 species). Mango (Mangifera indica), klengkeng (Euphoria longana), guava (Psidium guajava), are plants very potential to be developed because its favored by buyer. Bonsai plants such as anting putri (Wrightia religiosa) and Korean banyan (Ficus campanulata) have great economic and conservation potential because it has a high selling price and high fruiting frequency.

Abstract

Abstrak (Biji Arenga pinnata memiliki kulit biji  keras dan berlignin sehingga menghambat masuknya air ke dalam biji. Lapisan lignin pada kulit biji dapat didegradasi melalui reaksi kimia maupun perlakuan fisik. Perendaman biji aren dengan asam kuat (HNO3, H2SO4, dan HCl) dan pengamplasan akan mempengaruhi laju imbibisi air melewati kulit biji. Variabel bebas dalam penelitian ini adalah konsentrasi asam kuat (HNO3, H2SO4, dan HCl), luas pengamplasan, air panas, lama perendaman, sedangkan variabel terikat laju imbibisi pada biji aren. Konsentrasi asam kuat yang digunakan adalah 1M dan 0,5M untuk masing-masing HNO3, H2SO4, dan HCl. Pengamplasan dilakukan di bagian pangkal biji, dan luas pengamplasan bervariasi (tanpa amplas, amplas ½ bagian, dan amplas keseluruhan). Setiap perlakuan direndam selama 18, 24 dan 36 jam. Biji aren yang diberi perlakuan fisik maupun kimia mengalami pengelupasan kulit biji. Laju imbibisi biji pada perendaman 24 jam lebih tinggi dibandingkan dengan lama perendaman 18 maupun 36 jam. Laju imbibisi tertinggi terjadi pada waktu perendaman 1M HCl dan amplas penuh dengan lama perendaman 24 jam sebesar 0,038 ± 0,002 mL/jam dan 0,038 ± 0,007 mL/jam . Biji aren yang diberi perlakuan fisik dan kimia mulai berkecambah 7 minggu setelah tanam dengan daya kecambah tertinggi pada pemberian HNO3 dan lama perendaman 18 jam.Abstract Arenga pinnata seed has a hard seed coat and lignin that inhibit the absorption of water into the seed. The lignin in the seed coat can be degraded by chemical or physical treatments. Soaking of the palm seeds into strong acids (HNO3, H2SO4, or HCl) and sanding may affect the imbibition rate. The research was conducted to investigate the effect of a strong acid, sanding, and soaking time to the imbibition rate of A. pinnata seed. The independent variables in this research are concentration of the strong acids HNO3, H2SO4, and HCl; sanding, and soaking time, while the dependent variable is the rate of imbibition of A. pinnata Merr. The concentrations of the strong acid used were 1M and 0.5M. The sanding was performed on the base of seeds, which were varied into without sanding, ½ parts, and full sanding). The soaking durations were for 18, 24 and 36 hours. Palm sugar seeds treated by physical or chemical showed damage of the skin seeds. The seeds soaked with strong acid absorbed more water than the sanding and control treatments. The rate of imbibition for a 24-hour soaking showed imbibition rate higher than the 18 or 36-hour soaking. The highest rates of imbibition occurred on the treatments of 1M HCl soaking and 24 hours full sanding which were 0.038 ± 0.002 mL/h and 0.038 ± 0.007 mL/h, respectively. The seeds by physical and chemical treatments started their germination in seven weeks after planting with the highest germination from the treatments of HNO3 and 18 hours soaking time.Permalink/DOI: http://dx.doi.org/10.15408/kauniyah.v10i2.4758
