Penelitian ini bertujuan untuk mengetahui pengaruh bokashi cair berbahan dasar limbah Biogas (Slurry) dan Ekstrak (Chromolaena odorata) terhadap tingkat pertumbuhan awal lamtoro (Leucaena leuccephala). Penelitian menggunakan rancangan acak lengkap (RAL) yaitu dengan 4 perlakuan dan  yang diulang sebanyak 4 kali sehingga di dapat 64 ulangan. Adapun perlakuan yang diberikan adalah R0 = Tanpa pemberian bokashi cair, R1 =  Pemberian bokashi cair dengan dosis 50 ml/1 liter air, R2 =  Pemberian bokashi cair dengan dosis 150 ml/1 liter air, R3 = Pemberian bokashi cair dengan dosis 250 ml/1 liter air. Variabel yang diamati adalah tinggi tanaman, diameter batang, jumlah tangkai daun, bobot segar tanaman, dan bobot kering. Dari hasil analisis dan pembahasan yang dilakukan maka dapat disimpulkan bahwa pemberian bokashi dengan level (250 ml/1 liter air) memberikan tinggi tanaman tertinggi, diameter batang terbesar, jumlah tangkai daun terbanyak, berat segar tanaman terberat dan berat kering tanaman terberat.

Abstract. Syahbudin A, Meinata A, Arifriana R, Wiyono. 2020. The composition of undergrowth vegetation in the Gendol Riverbank, Sleman District, Yogyakarta, Indonesia. Biodiversitas 21: 1786-1792. Gendol river is one of the rivers affected by a pyroclastic blast from Mount Merapi eruption in 2010. This river flows through several villages, such as Glagaharjo, Kepuharjo, Wukirsari, and Argomulyo. On this riverbank, vegetation has grown naturally post-eruption of Mount Merapi and is continues to change. Some vegetation was also planted by the community. This study aims to find out the composition of the undergrowth vegetation on the Gendol riverbank in Cangkringan Sub-district. The data was obtained systematically by marking 10 sample plots of 5 m x 5 m and 2 m x 2 m size, on each side of the bank. A total of 68 species were recorded in this study which consisted of 29 trees species in seedlings and saplings stage, 34 species of herbs and shrubs, and 6 species of grasses. The dominant among the non-tree species are Chromolaena odorata (L.) R.M.King & H.Rob. with an IVI of 43.78%, Alternanthera brasiliana (L.) Kuntze with IVI of 16.6% and Asystasia gangetica (L.) T. Anderson with IVI of 15.78%. Saplings are dominated by Falcataria moluccana (Miq.) Barneby & J.W. Grimes with IVI of 32.81%, followed by Leucaena leucocephala (Lam.) De Wit (IVI-24.41%) and Melia azedarach (IVI-14.28%).

Tujuan penelitian ini adalah menentukan efek ekstrak metanol dan partisi kulit batang kayu jawa dalam menghambat pertumbuhan sel kanker HeLa dan sel kanker MCF-7. Simplisia kulit kayu dimaserasi menggunakan pelarut metanol. Ekstrak kemudian dipartisi secara partisi cair padat menggunakan pelarut heksan. Pemisahan menghasilkan partisi larut heksan dan partisi tidak larut heksan. Pengukuran aktivitas inhibisi pertumbuhan sel dilakukan menggunakan metode MTT Assay terhadap sel HeLa, sel MCF-7 dan sel Vero. Senyawa yang dikandung diidentifikasi dengan beberapa pereaksi golongan. Hasil penelitian menunjukkan bahwa ekstrak metanol, partisi tidak larut heksan dan partisi larut heksan dapat menghambat pertumbuhan sel kanker Hela dengan nilai indeks selektivitas, berturut-turut, 2,04; 1,85 dam 4,19. Sedangkan untuk sel MCF-7, indeks selektivitas, berturut-turut, 1,91; 1,44 dan 2,13. Partisi larut heksan dapat memiliki potensi sebagai antikanker dengan selektivitas yang baik.

Broussonetia papyrifera is an exotic tree widely grown for paper production. Due to its prolific regeneration it has invaded forestcanopy gaps and degraded farmlands and has now become an invasive species in Ghana. In enhancing its value for use the plantwas evaluated as potential forage for grazing animals vis-à-vis other two existing forage plants: Ficus exasperata and Leucaenaleucocephala.The study assessed the palatability and preference of Broussonetia papyrifera using sheep and goats for the wet anddry seasons.The species were assessed in indoor pen feeding trials using eight-unit (3×3 m) pens with the cafeteria method.The amount of forage offered was 100g (fresh material) in all instances for each species and for ten minutes. Adesign basedon 3×2×2 factorial in Randomized Complete Block Design (RCBD) was used to test the differences in palatability betweenthe three forage species.Results revealed that palatability was higher (P<0.05) in Leucaena leucocephala compared with Ficusexasperata and Broussonetia papyrifera for sheep and goats across seasons. The trend shown might be the result of the effectsof familiarity with the Leucaena leucocephala since animals tend to select plants that are familiar than newly introduced andunfamiliar plants. The study also revealed high level of condensed tannin (CT) in Broussonetia papyrifera which might haveinterfered with forage intake by the animals.There were no significant differences in palatability of Broussonetia papyrifera forgoat in both dry and wet season interactions and Ficus exasperata for goat in both dry and wet season interactions (P>0.05).Thestudy concluded that Broussonetia papyrifera could be a potential feed for both sheep and goats across seasons.The researchrecommended that livestock farmers should incorporate Broussonetia papyrifera feed into their programmes for both sheep andgoats and should be introduced to animals from infancy so that it may become a familiar feed for them.

Diabetes melitus merupakan suatu penyakit dengan adanya gangguan sekresi insulin baik karena penurunan sensitifitas maupun kerusakan pada sel beta. Tujuan penelitian ini adalah membuktikan ekstrak daun petai cina (Leucaena leucocephala (Lam.) de Wit) memiliki aktivitas menurunkan kadar gula darah mencit hiperglikemik pada dosis yang efektif. Penelitian antihiperglikemik ini menggunakan mencit putih sebanyak 30 ekor. Pengujian aktivitas antihiperglikemik dilakukan pada 6 kelompok perlakuan yaitu kelompok I (kontrol normal), kelompok II (kontrol negatif, induksi aloksan 200 mg/kg BB dan akuades), kelompok III (induksi aloksan dan glibenklamida 10 mg/kg BB), kelompok IV (induksi aloksan dan ekstrak daun petai cina 200 mg/kg BB), kelompok V (induksi aloksan dan ekstrak daun petai cina 400 mg/kg BB), kelompok VI (induksi aloksan dan ekstrak daun petai cina 300 mg/kg BB). Semua kelompok perlakuan diberikan perlakuan tersebut selama 14 hari dan dilakukan pengukuran kadar gula darah pada hari ke-0, 3, 10, dan 17. Aktivitas antihiperglikemik ekstrak daun petai cina ditunjukkan dengan cara menghitung daya hipoglikemik masing-masing perlakuan. Hasil penelitian menunjukkan bahwa ekstrak etanol daun petai cina mempunyai aktivitas antihiperglikemik pada mencit yang diinduksi aloksan. Pada dosis uji ekstrak etanol daun petai cina 600 mg/kg BB mempunyai aktivitas antihiperglikemik yang efektif dibanding dengan dosis 400 mg/kg BB dan 200 mg/kg BB yang sebanding dengan kelompok kontrol positif.

Bentinckia condapanna shows more IVI values and there by dominance and ecological stress in both the sites, that is, in sparsely distributed habitats as well as in dominated habitats (Site-II). Major associations /co dominance to Bentinckia condapanna in site -I were the evergreen species like Macaranga peltata, Elaeocarpus tuberculatus, Lannea coromandelica, Schefflera venulosa etc. and for site-II was the secondary species Chionanthus ramiflorus. Higher IVI values for Bentinckia condapanna in both the sites proves the capacity of this species to establish in mono-dominant and co- dominant communities.

Several studies have demonstrated the biological efficacy of leaf, stem and root powders or extracts of Chromolaena odorata (L.) King and Robinson against insect pests but those that are focused on the biological efficacy of aqueous leaf extracts against Macrotermes species are scanty. Current management of termites with synthetic insecticides is being discouraged due to human and environmental hazards. Therefore, the insecticidal effectiveness of aqueous leaf extract C. odorata against Macrotermes species was investigated. Five concentrations (0, 2.5, 5.0, 7.5 and 10.0% (w/v)) of the aqueous extract of C. odorata plant were evaluated for repellency and toxicity on the worker caste of Macrotermes species following standard procedures. The filter paper impregnation technique was used for the bioassay. Percentage repellency was monitored for 30 minutes and mortality recorded at 12, 24 and 36 hours post exposure. The leaf extract of C. odorata significantly repelled 95% of Macrotermes species at the highest concentration of 10% (w/v) after 30 minutes post treatment exposure. Mortality of Macrotermes species was independent of treatment concentration, but dependent on duration of exposure. All treatment concentrations of aqueous leaf extract of C. odorata caused significant mortality against Macrotermes species ranging between 94% and 98% compared to the control; indicating very great potential for adoption and use in the management of Macrotermes species.
