Belaran Tapah (Merremia peltata) is a plant used by the community around the Special Purpose Forest Area (KHDTK) of Lambung Mangkurat University (ULM) as traditional medicine. The purpose of this study was to determine the presence of secondary metabolites in the Belaran Tapah plant with a qualitative phytochemical test which is expected to provide information about the content of secondary metabolites for the Belaran Tapah plant which is capable of being the basis for sustainable use of plants that have medicinal abilities. The sample came from KHDTK ULM, while the Wood Science Laboratory, Faculty of Forestry, ULM, was the place for testing. The method uses phytochemical screening which identifies flavonoid compounds, quinones, saponins, steroids, tannins, triterpenoids, and alkaloids with objects including roots, stems, leaves, and bark. The test results were processed into tabulated data and analyzed descriptively. Secondary metabolites indicated on stems, bark, leaves, and roots showed that the most identified compounds were saponins, almost all parts of the belaran tapah, kilayu and slapped rhino plants, except for the slapped rhino stems. Alkaloids, triterpenoids, steroids and quinones were found only in some parts of the roots, stems, leaves and bark, while flavonoids were not present in all of these plants.Belaran Tapah (Merremia peltata) merupakan tumbuhan yang digunakan masyarakat sekitar Kawasan Hutan Dengan Tujuan Khusus (KHDTK) Universitas Lambung Mangkurat (ULM) sebagai obat tradisional.

The purpose of this study was to qualitatively identify active chemical compounds, namely the content of alkaloids, flavonoids, steroids, triterpenoids, tannins, saponins, and quinones, in the roots, bark and leaves of Jelatang Gajah. The method used is phytochemical screening by identifying using various active compounds in the simplicia of the Jelatang Gajah plant. Flavonoid chemical compounds in this test were not detected, because the solution did not change color. Steroid chemical compounds from 3 (three) times the repetition of the section show a strong / sharp indication value (++) which is indicated by a dark red color change in the phytrate. Triterpenoids were not detected in the three simplicia, the phytrate that had been made did not change color, indicating the presence of triterpenoid compounds. The result of the (+) value in triterpenoid compounds was indicated by a change in green color. Tests for tannin compounds in the elephant nettle plant study found a weak indication (+) in leaf and bark simplicia, while in the simplicia of tannin roots it was not detected (-). Tujuan dari penelitian ini untuk mengidentifikasi secara kualitatif kandungan alkaloid, flavonoid, steroid, triterpenoid, tanin, saponin, dan quinon, pada bagian akar, kulit, dan daun jelatang gajah. Metode yang digunakan yaitu skrining fitokimia dengan mengidentifikasi menggunakan berbagai senyawa aktif pada simplisia tumbuhan Jelatang Gajah. Senyawa kimia flavonoid pada pengujian ini tidak terdeteksi, karena larutan tersebut tidak terjadi perubahan warna. Senyawa kimia steroid dari 3 (tiga) kali ulangan bagian tersebut menunjukkan nilai indikasi kuat/tajam (++) yang ditunjukkan dengan adanya perubahan berwana merah pekat pada fitrat tersebut. Triterpenoid tidak terdektesi pada ketiga simplisia, fitrat yang telah dibuat tidak terjadi perubahan warna yang menunjukkan adanya senyawa triterpenoid. Hasil nilai (+) pada senyawa triterpenoid ditandai dengan terjadinya perubahan warna hijau.Pengujian senyawa tanin pada penelitian tumbuhan jelatang gajah ini ditemukannya indikasi lemah (+) pada simplisia daun dan kulit, sedangkan pada simplisia akar tanin tidak terdeteksi (-).

The purpose of this study is to analyze the physical and mechanical properties of the particle board of sengon wood powder (Paraserianthes falcataria) using PVAC adhesives and to analyze the suitability of wood as raw material for particle board. The method used is physical properties testing in the form of testing water content and density as well as testing mechanical properties in the form of flexural strength (MoE) and fracture firmness (MoR). The physical properties of the particle board with the addition of different adhesives between 1.0.54-1.0.63 grams each treatment did not significantly affect the value of water content. Overall average water content reaches less than 14% that has met SNI, each treatment has no significant effect on the density value, the density value meets the Indonesian National Standard (SNI) with SNI requirements for particle board density of 0.4-0.9 gr / cm3 (low density), the average modulus of elasticity (MoE) produced had a very significant effect and fulfilled the SNI for particle board min 20400 kgf / cm2 in A2 treatment, but did not meet the standards in A1 and A3 treatments, the average value of fracture constancy (MoR) for each treatment has a very significant effect and according to the standards set SNI min 82 kgf / cm2 already meets the standard in A2 treatment with a ratio between powder and adhesive 1: 0.58 while it does not meet the standard in treatment A1 , and A3. The suitability of Sengon wood powder (Paraserianthes falcataria) to the physical and mechanical properties of the particle board in the form of water content, density, flexural strength (MoE) and fracture firmness (MoR) for each given treatment is appropriate because most have met the Standard Indonesian National (SNI).Keywords: Particle Board, Physical Properties, Mechanical Properties

The use of halaban bark as a raw material for natural-based medicines has enormous potential. This study aims to identify the phytochemical content in the form of flavanoids, tannins, steroids and triterpenoid alaban bark (Vitex pubescens Vahl) based on the height of the alaban tree. To find out the presence of active compounds contained in alaban bark, test samples were taken in the form of bark taken based on the difference in height of the place where alaban trees grew, namely low altitude, medium height and high altitude. The presence of the highest phytochemical content is found in tannin active compounds which show that all of the test samples are positively containing tannins. For flavonoid active compounds, of the entire test sample there were only 2 test samples which showed negative results, namely at low altitudes. Whereas the highest active steroid compound was found in the test sample at low altitude and the highest triterpenoid active compound was found in the test sample at high altitude.Keywords : Alaban; Tree bark; Phytochemicals; height of place

This study is to determine the quality of honey at various storage times in 2016 (A1), 2017 (A2), 2018 (A3). Parameters tested were reducing sugar content and acidity.The results of testing the quality of honey are determined based on the Indonesian National Standard (SNI) 01-3545: 2013. The results of testing the quality of kelulut honey (Trigona sp) until the age of 2 years are better when viewed from reducing sugar content. The reducing sugar level is set at a minimum of 65% b / b. Honey A1 (2016) with the highest sugar content of 67.2%. A2 honey sugar content (2017) is 66.5%. While A3 honey (2018) only reached 60.7%. Kelulut honey that is still fresh or stored until the age of 2 years cannot reach the SNI for its acidity. The acidity of honey in A1 (2016) reached 295.82 ml NaOH / Kg, A2 (2017) 369.06 ml NaOH / Kg, and the others A3 (2018) 474.34 ml NaOH / Kg. it's too acidic (> 50 ml NaOH / Kg). The high levels of honey acidity reduce the quality of kelulut honey, but the acidity of honey decreases, seen from the longer storage time.Keywords: Trigona Sp, Kelulut Honey, Quality of honey , Reducing Sugar, acidity of honey
