It tastes sweet, with fragrant aroma and thin skin. Its cultivation, however, needs improvement to gain better quality of product. One effort that is using the in vitro culture. The study aimed to determine the best IBA and NAA concentrations to trigger root formation on siam orange transplant and used Completely Randomized Design (CRD). The result showed that the rooting reached 100% on all treatments. The fastest rooting was observed in 2 mg/L IBA treatment (7.67 days after planting). The most root growth was obtained with combination of 0.5 mg/L NAA with 1.5 mg/L IBA (2.67 units). The longest root was obtained through the mixture of 1.5 mg/L NAA with 0.5 mg/L IBA (2.27 cm).

In vitro culture is an alternative way to get large number and uniform mangosteen seedling. The purpose of this research was to determine the best concentration of BAP (Benzylaminopurine) in LQGXFLQJ PDQJRVWHHQ ¶V VKRRWV IURP %HQJNDOLV 7KLV UHVHDUFK XVHG 5DQGRPL]HG Complete block Design (RAK) with 5 concentrations of BAP (0; 1; 3; 5; 7 mg/l) with 5 replications. The result of this research showed the fastest shoot forming time and highest number of shoots present in a concentration of 5 mg / l BAP at 13 DAP and 2 shoots per explant.

Some of weed controls use synthetic and organic herbicides. Organic herbicides are used as the environmentaly friendly weed control. One of potential plants as organic herbicides is Peperomia pellucida that contains allelopathic compound and essensial oil. The purposes of this research were to determine the effect of P. pellucida extract and the most effective and efficient extract concentration in inhibiting the germination and growth of Mikania micrantha. This research used Randomized Complete Design using four treatments, i. e. control, 7,5%, 15% and 30% of P. pellucida extracts. The collected data was analyzed using Analysis of Variance (ANOVA) and followed by Duncan's Multiple Range Test (DMRT) if the result was significantly different. The result showed the decrease of the germination and growth of M. micrantha weed. The most effective and efficient extract was 7,5% P. pellucida extract.

One of plant species that can be extracted as natural dye source and contains anthocyanin is senduduk (Melastoma malabathricum L.). The objective of this study was to compare the effectivenes of various solvents and organic acids in extraction process of antocyanin pigment from senduduk flower. The results showed that the color of anthocyanin extracts that produce the strongest color was found in 3% ethanol and 1% tartaric acid treatment, while the weakest color was found in 3% ethanol treatment. Low pH was produced in 3% ethanol + 1% tartaric acid, while high pH was produced in 3% ethanol treatment.

The aim of this study was to determine the effect of BAP and NAA concentration in the root orchid propagation G. scriptum var. citrinum. The results showed that the application of BAP and NAA significant effect on the time of formation appeared roots (19 days), the best root number in the treatment of BAP 0.5 mg/l + 1.0 mg/l NAA for (5 pieces) and root length was obtained NAA 1 mg/l and a combination of 1.0 mg/l BAP + 0.5 mg/l NAA respectively 6.66 cm and 7.40 cm.

Penelitian ini bertujuan untuk mengkarakterisasi morfologi (rhizoma, ptiolus dan lamina) dan mikromorfologi (sisik dan trikoma) dari 4 jenis Pyrrosia yang umum dijumpai di Provinsi Riau, yaitu Pyrrosia heterophyla, Pyrrosia lanceolate, Pyrrosia longifolia dan Pyrrosia pillosheloides. Hasil karakterisasi morfologi menunjukan variasi pada organ yang diamati, terutama pada ukuran ptetiolus, bentuk dan ukuran lamina. Hasil pengamatan pada sisik menujukan varias pada warna sisik, jumlah rambut pada sisik dan posisinya. Sedangkan trikoma pada ptiolus dan lamina menunjukan persamaan bentuk yaitu stelata.

Tujuan kegiatan ini adalah untuk mengurangi sampah di lingkungan masyarakat, meningkatkan kemampuan ekonomi keluarga, dan minat masyarakat mengkonsumsi sayuran yang bersih dan higienis di Desa Kualu Kecamatan Tambang Kabupaten Kampar. Teknik hidroponik ini terbuat dari bahan relatif murah dan terjangkau, sehingga keterbatasan kemampuan finansial masyarakat dapat teratasi. Sistem ini merupakan sistem hidroponik yang menggunakan sumbu untuk menyerap nutrisi organik. Untuk meminimalisir biaya pembelian nutrisi dapat diatasi dengan inovasi larutan hara dari sampah buangan rumah tangga menjadi pupuk cair. Pelaksanaan pengabdian kepada masyarakat ini menggunakan metode penyuluhan, diskusi dan pembuatan teknologi hidroponik. Masyarakat sangat antusias mengikuti program ini, te...
