Abstract

ABSTRAKPenelitian ini merupakan penelitian ekperimen yang bertujuan untuk mengidentifikasi senyawa metabolit sekunder yang terdapat dalam ekstrak etanol batang bajakah tampala (Spatholobus littoralis Hassk) dan untuk mengetahui mengetahui bioaktivitasnya dan komponen senyawa yang terdapat dalam ekstrak tersebut. Sampel penelitian diambil dari Provinsi Kalimantan Timur. Tahapan penelitian meliputi preparasi sampel, ekstraksi dengan maserasi, uji fitokimia, identifikasi senyawa dengan GC-MS dan uji bioaktivitas dengan metode BSLT. Hasil uji fitokimia menunjukkan adanya senyawa golongan flavonoid, saponin, fenolik, triterpenoid dan steroid. Adapun hasil identifikasi senyawa secara GC-MS menunjukkan keberadaan metabolit sekunder golongan fenolik dan steroid. Nilai LC50 pada uji bioaktivitas adalah 94,08 ppm atau 94,08 μg/mL. Nilai tersebut di atas menandakan bahwa ekstrak batang bajakah tampala memiliki potensi aktivitas biologis yang sangat tinggi sehingga berpotensi sebagai anti kanker dan anti bakteri.Kata Kunci: Bajakah Tampala, Spatholobus littoralis Hassk, dan SteroidABSTRACTThis study is an experimental study that aims to identify secondary metabolite compounds contained in ethanol extract of bajakah tampala stem (Spatholobus littoralis Hassk) and to determine its bioactivity and the components of the compounds contained in the extract. The research samples were taken from East Kalimantan Province. The research stages include sample preparation, extraction by maceration, phytochemical test, compound identification by GC-MS and bioactivity test by BSLT method. The results of phytochemical tests showed the presence of flavonoid, saponin, phenolic, triterpenoid and steroid compounds. The results of compound identification by GC-MS showed the presence of secondary metabolites of phenolic and steroid groups. The LC50 value in the bioactivity test was 94.08 ppm or 94.08 μg/mL. The value above indicates that bajakah tampala stem extract has a very high potential biological activity so that it has the potential as anti-cancer and anti-bacterial.Keywords: Bajakah Tampala, Spatholobus littoralis Hassk, and Steroids

Abstract

Penelitian ini bertujuan untuk mengetahui karakteristik karbon aktif tempurung kelapa sawit teraktivasi H3PO4 10%, mengetahui kapasitas adsorpsi dan efisiensi adsorpsi sistem kontinyu pada adsorpsi zat warna Remazol Brilliant Blue-5R (RBV5R). Penelitian ini meliputi preparasi tempurung kelapa sawit, karbonisasi, aktivasi karbon, uji karakteristik, dan adsorpsi zat warna RBV5R secara sistem kontinyu. Karakteristik karbon aktif diperoleh kadar air sebesar 7,58%, kadar abu 7,86% dan kadar zat terbang 94,12%. Kadar air dan kadar abu yang dihasilkan telah memenuhi SNI 06-3730-1995 sedangkan kadar zat terbang belum memenuhi SNI 06-3730-1995. Adsorpsi zat warna RBV5R secara sistem kontinyu memiliki waktu kontak optimum 80 menit dengan kapasitas adsorpsi sebesar 2,0460 mg/g dan efisiensi adsorpsi sebesar 27,2797%.This study aims to determine the characteristics of activated palm oil carbon activated with H3PO4 10%, determine the adsorption capacity and adsorption efficiency of the continuous system on the adsorption of Remazol Brilliant Blue-5R (RBV5R) dye. This research includes preparation palm kernel shell, carbonization, carbon activation, characteristic test, and adsorption of RBV5R dye in a continuous system. The characteristics of activated carbon obtained moisture content of 7.58%, ash content of 7.86% and fly substance content of 94.12%. The moisture content and ash content produced have met SNI 06-3730-1995 while the fly content has not met SNI 06-3730-1995. Adsorption of RBV5R dye in a continuous system has an optimum contact time of 80 minutes with an adsorption capacity of 2.0460 mg/g and an adsorption efficiency of 27.2797%.
