Abstract

The titan arum (Amorphophallus titanum (Becc.)), an endangered and endemic flora from the island of Sumatra, faces a significant risk of extinction. Conservation efforts for the titan arum were undertaken, including in vitro conservation through tissue culture. The study aimed to determine the optimal concentration of the growth regulator Benzyl Amino Purine (BAP) for inducing shoot formation in titan arum and to observe cellular changes during the shoot stage through histological test. This research was conducted from November 2023 to March 2024 at the Tissue Culture Laboratory, Andalas University. The experiment was arranged in a Completely Randomized Design (CRD) with five treatment levels: 2, 3, 4, 5, and 6 ppm.  Data analysis was performed using an F-test at a 5% significance level. If the F-test showed significant differences, further testing was carried out using Duncan's Multiple Range Test (DMRT) at a 5% significance level. Meanwhile, data on explant rooting percentage and root count were presented as means and standard deviations. Results indicated that various concentrations of BAP could induce shoots formation of Amorphophallus titanum Becc., with the percentage of explants forming shoots reaching 80–95%.  The concentration of 5.0 ppm BAP was the most effective, yielding the highest average number of shoots at 7.80. Histological test revealed cell enlargement at the shoot tips. This research is pivotal for the conservation of titan arum and promotes further studies in in vitro culture techniques.

Abstract

Pakcoy menjadi salah satu tanaman yang banyak disukai oleh masyarakat_khususnya di Indonesia karna mengandung banyak manfaat dan vitamin yang tinggi. Nutrisi merupakan kunci utama dalam budidaya hidroponik. Pemupukan dapat dilakukan melalui daun. pemupukan harus diimbangi dengan dosis yang tepat agar memberikan hasil yang maksimal, kandungan nutrisi yang terkandung pada pupuk cair dapat memengaruhi kandungan klorofil yang dapat memengaruhi kandungan serat kasar tanaman dan juga vitamin C pada tanaman. Penelitian ini bertujuan untuk mendapatkan interaksi serta jenis dan dosis terbaik pada klorofil total, kandungan serat kasar serta vitamin C pada tanaman pakcoy Penelitian ini dilaksanakan pada bulan September – Oktober 2024 di Green House Arif Hydrofarm Kota Padang, Laboratorium Fisiologi Tumbuhan Fakultas Pertanian, dan Laboratorium Teknologi Pengolahan Hasil tTanaman Fakultas Teknologi Pertanian Universitas Andalas. Penelitian ini disusun dalam Rancangan Petak Terbagi (RPT) factorial. Faktor pertama yaitu atas 5 jenis pupuk (Good Grow, Gandasil, Ferti Grow, Yield More dan NPK Vertine) dan faktor kedua yaitu 4 dosis pupuk (0 ml/L, 5 ml/L, 10 ml/L dan 15 ml/L.). Data dianalisis dengan uji F pada taraf 5%, jika F hitung lebih besar dari pada F table, maka dilakukan uji lanjut Duncan Multiple Range’s Test (DNMRT) pada taraf 5%. Hasil yang didapatkan terdapat interaksi pemberian jenis pupuk dan dosis pupuk cair pada klorofil total daun tanaman pakcoy. Pemberian pupuk cair Good Grow memberikan terbaik terhadap klorofil daun dan peningkatan serat kasar serta Vitamin C yang dibudidayakan pada sistem NFT dengan AB Mix 700 ppm. Dosis 15 ml/L memberikan pengaruh terbaik terhadap klorofil total daun dan peningkatan serat kasar serta vitamin C tanaman Pakcoy yang dibudidayakan pada sistem NFT dengan AB Mix 700 ppm. terdapat interakasi pada kandungan klorofil total, dan adanya peningkatan kandungan serat kasar dan kandungan Vitamin C pada pemberian pupuk Grow Good dengan dosis 15 ml/L.

Abstract

Dog fruit (Pithecellobium lobatum Benth, synonyms P. jiringa, Archidendron pauciflorum) is one of the popular tropical plants. The objectives of this research are to determine the best (i) the best genotype for germination and growth of dogfruit seedlings (ii) combination of shade and genotype, (iii) the best percentage of shade and. This research was carried out by direct observation of seed germination and seedling formation. The study was carried out in an experimental garden located ± 255 meters above sea level. The average temperature and mean humidity during the experiment were 27 ºC and 65%, respectively. The experiment used a completely random design consisting of two factors. The first factor was shade (0%, 40%, or 80% shading). The second factor was genotype (bareh and lokan). Data were analysed using analysis of variance and significant differences were further analysed using Duncan’s New Multiple Range Test at the 5% level. Observations for determining the time of radicle appearance, root length, radicular colour, and germination type seeds were germinated in seedbeds. Temperature and humidity were recorded in every observation. The best interaction with respect to leaf area is 80% shade cloth and the lokan genotype. Eighty percent shade cloth is the best for germination and growth of Dogfruit seedlings. The best genotype for germination and growth is lokan. It is recommended to use 80% shade cloth because it provides optimal growth of Dogfruit seedlings.

Abstract

Shallot (Allium ascolanicum L.) is one of the horticultural crops that is widely consumed by humans. This study aims to obtain interaction the type of mulch and doses of chicken manure on the growth and yield of shallots. This Research was conducted at Panai Pasir Talang , Muara Labuh, South Solok Regency with a height of ± 430 meters above sea level, in December 2018 to February 2019. The research method is an experiments used factorial complete randomized design with two factors. Factors I is the type of mulch (black plastic mulch, silver plastic mulch, rice straw mulch) and factors II is chicken manure (10 tons / ha, 20 tons / ha and 30 tons / ha).. The results showed that there was no interaction between the use of several types of mulch with chicken manure doses on the growth and yield of shallots. The use of black plastic mulch yielded the best results on fresh tuber weight per plot and per hectare of onion namely 1,643 kg / plot and 11.74 tons / ha. The dose of chicken manure of 20 tons / ha gave the best influence on plant height, number of leaves, fresh tuber weight per clump, per plot and per hectare as well as wind dry weight per clump, per plot and per hectare of onion.

Abstract

Tanaman gambir (Uncaria gambir (Hunter) Roxb) merupakan komoditi unggulan Sumatera Barat penghasil senyawa polifenol terutama katekin yang memiliki manfaat sebagai antioksidan sehingga digunakan dalam berbagai bahan baku industri seperti farmasi, kosmetik, dan pangan. Prospek pasar ekspor yang tinggi namun mutu gambir yang diekspor masih rendah. Penggunaan kultur suspensi sel dengan penambahan elisitor seperti ion tembaga Cu²⁺ dapat menjadi solusi efektif dengan meningkatkan produksi metabolit sekunder dalam jumlah banyak dan waktu singkat. Penelitian ini bertujuan untuk mendapatkan konsentrasi elisitor Cu2+ terbaik dalam peningkatan kandungan katekin kalus gambir. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan pemberian elisitor Cu2+ (0, 2, 4, dan 6 mg/l) sebagai perlakuan. Hasil penelitian menunjukkan bahwa pemberian elisitor Cu2+ belum mampu untuk meningkatkan kandungan senyawa katekin pada kalus gambir karena hanya ditemukan pada perlakuan 0 ppm 7 HSS dan terdapat beberapa senyawa bioaktif yang muncul pada kromatogram pengujian HPLC yang tidak dapat teridentifikasi oleh standar katekin yang digunakan.

Abstract

Gambir (Uncaria gambir Roxb.) is an important Indonesian export commodity used in the pharmaceutical, food, and leather tanning industries. The Cubadak variety is one of the superior varieties with high flavonoid and tannin content and resistance to pests and diseases. One of the obstacles in gambir propagation is uneven seedling growth, which affects plant productivity and quality. One approach to address this issue is by regulating light intensity through shading during the gambir seedling phase. This study aims to investigate the effect of shading intensity on the growth of Cubadak gambir seedlings. The study was conducted at the Experimental Garden of the Faculty of Agriculture, Andalas University, using a Completely Randomized Design (CRD) with four levels of shading intensity (40%, 50%, 60%, and 70%) and three replications. Data were analyzed using an F-test at the 5% level, followed by Duncan’s New Multiple Range Test (DNMRT) at the 5% significance level. The results of the study indicated that 60% shading provided the best effect on gambir seedling growth, as evidenced by increased plant height, number of leaves, leaf area, and other morphological and physiological parameters. A shading intensity of 60% is recommended as the optimal condition for the growth of Cubadak gambir seedlings.
