Abstract

Nilam (Pogostemon cablin Benth.) merupakan tanaman penghasil minyak atsiri potensial di Indonesia. Tingginya permintaan minyak nilam tidak diikuti oleh produksinya. Produktivitas nilam yang rendah salah satunya disebabkan oleh kurangnya ketersedian bibit bermutu. Salah satu metode alternatif perbanyakan bibit unggul dalam waktu relatif singkat dapat dilakukan melalui kultur jaringan. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian beberapa konsentrasi zat pengatur tumbuh Benzile Amino Purin (BAP) terhadap multiplikasi tunas nilam secara in vitro. Penelitian telah dilaksanakan pada bulan Maret sampai Mei 2022 di Laboratorium Kultur Jaringan Departemen Agronomi, Fakultas Pertanian Universitas Andalas, Padang. Penelitian disusun berdasarkan rancangan acak lengkap dengan konsentrasi BAP sebagai perlakuannya yang terdiri dari empat taraf, yaitu 0 ppm; 0.5 ppm; 1 ppm dan 1.5 ppm pada media MS (Murashige dan Skoog). Hasil penelitian menunjukkan bahwa konsentrasi BAP sebanyak 0.5 ppm merupakan perlakuan terbaik yang mampu menghasilkan tunas sebanyak 134.6 tunas.

Abstract

The community service took place for the Women Farming Group (WFG) of Banda Langik in the Sungai Bangek, Balai Gadang, Koto Tangah District, Padang City, from July to November 2022. It was held in demonstration plots (dump lots) of Liquid Organic fertilizers (LOF) with coconut coir, and banana stems as raw materials. These raw materials were straightforward to find in this area. Plots were made of 2 beds, and each was planted with pull-out Kale from seeds. Each bed was divided into two parts: without LOF and given LOF. It helped the WFG members differentiate the growth and yield pull-out Kale between being given LOF and without LOF. LOF was made by fermenting coconut coir separately and banana stems in a closed bucket for two weeks. The fermented products were sprinkled on the plants every week, starting at the age of two weeks after planting until they were close to harvest. The results showed that the plants given LOF were higher than those without LOF. The plant has given LOF more leaves. Their length and width of leaves were more significant than those without LOF. LOF is very useful given to vegetable plants, especially pull-out Kale.

Abstract

Coconut plants are an important commodity for Indonesian people. In the cultivation process, coconut plants need a suitable environment for growth and production. One of the problems in cultivation is weeds. Weeds have a negative impact on cultivated plants, therefore appropriate control measures are needed. So far, the most effective weed control is chemical methods using herbicides. One of the herbicides that can be used is the herbicide with isopropyl amine glyphosate 165 SL. The aim of the experiment was to determine the efficacy of the herbicide isopropyl amine glyphosate 165 SL for controlling weeds in coconut cultivation was conducted from February to June 2022 at Pariaman City, West Sumatra Province. The experimental units were laid out according to a Randomized Block Design with 7 treatments and 3 groups as replications. The treatment was herbicide isopropyl amine glyphosate 165 SL at doses of 3.50 l ha-1, 5.25 l ha-1, 7.00 l ha-1, 8.75 l ha-1, 10.00 l ha-1, manual weeding and control (without weeding). The results of the research show that (1) The herbicide isopropyl amine glyphosate 165 SL can generally control weeds in coconut cultivation up to 12 weeks after application because the weed biomass in the treatment plot is relatively the same as manual weeding and is lighter than the control; (2) Herbicide isopropyl amine glyphosate 165 SL with a dose range of 3.50 l/ha – 10.50 l ha-1 up to 6 weeks after application does not show symptoms of phytotoxicity in coconut plants.

Abstract

Soybean (Glycine max L.) is a type of nutritious food crop because soybean seeds have high protein amino acid content. Increasing domestic production for soybean self-sufficiency needs to be done by expanding the planting area. The objective of this research is to examine the effect of ethyl methane sulfonate concentration and obtain soybean plants tolerant to drought and aluminum stress through in vitro selection. This research was conducted from November 2023 to January 2024 at the Tissue Culture Laboratory, Faculty of Agriculture, Andalas University. The research was arranged in a Completely Randomized Design consisting of 12 treatment levels of the combination of concentrations of abiotic selection agents PEG 4000 and AlCl3 induced by EMS mutation and 12 treatment levels of the combination of concentrations of abiotic selection agents PEG 4000 and AlCl3 not induced by EMS mutation with 3 replications. Data analysis was performed using independent sample t-test at a significance level of 5% and interpreted descriptively. The results showed that mutation induction using ethyl methane sulfonate (EMS) did not produce soybean somatic embryo mutants tolerant to drought and aluminum stress. Meanwhile, results from non-mutated callus produced somatic embryos suspected to be potential putative somaclonal candidates tolerant to drought and aluminum after double in vitro selection using 10% PEG 4000 and 150 ppm AlCl3 selection agents.

Abstract

The corpse flower (Amorphophallus titanum Becc.) is an endemic flora of Indonesia that is naturally found only in Sumatra. The status of A. titanum is endangered because of several factors: deforestation, tuber exploitation, long flowering time, and protogyne. Until now, there has been no research about the population and distribution of A. titanum in West Sumatra. This study aimed to obtain information about the population and distribution of A. titanum in West Sumatra, so this research is essential to learn. The research used roaming and snowball sampling methods in Solok Selatan and Sijunjung Regencies in September-October 2022. The research was conducted by recording the coordinates where A. titanum was discovered, marked using GPS, and collecting morphological characteristics. The results showed that exploration in the Solok Selatan District found 19 corpse flower individuals (18 species of A. titanum and one species of A. gigas). In contrast, exploration in Sijunjung Regency managed to found 25 species of A. titanum. The corpse flowers found were in vegetative, dormant, flowering, and fruiting phases. The results help record the number and distribution of A.titanum in West Sumatra. The ex-situ conservation program will use germplasm as propagation material in the future.

Abstract

Research findings must be disseminated to the public, either to specific groups or broadly, to create a positive impact on development. The Payo area in Solok City is an agrotourism region with potential for citrus cultivation and citrus-picking tourism. Socialization on land suitability studies and fertilization recommendations is essential to inform farmers. Recommendations for citrus cultivation in Payo serve as guidelines for the future development of citrus farming. This activity aims to deliver cultivation recommendations based on land suitability and fertilization, contributing to sustainable agricultural development. It was conducted in Nagari Payo, Solok City, covering several activities, including land suitability and agro-climate analysis using primary and secondary data, analysis of soil physical and chemical properties for fertilization recommendations, and socialization of citrus cultivation to the community. The analysis revealed that Payo is suitable for citrus planting, with recommended varieties such as Keprok Batu 55, Keprok Brastepu, Keprok Garut, Keprok Tejakula, and Siam Pontianak. However, soil fertility in Payo is generally low, necessitating improvement through liming, the application of ameliorants, and organic and inorganic fertilization. Evaluation of the activity showed that farmers were enthusiastic and understood the information provided. Three months after the activity, all planted seedlings were growing well.  Hasil penelitian harus disebarluaskan kepada masyarakat, baik kepada kelompok tertentu maupun publik, untuk memberi dampak positif pada pembangunan. Daerah Payo di Kota Solok merupakan kawasan agrowisata yang potensial untuk budidaya dan wisata petik jeruk. Sosialisasi mengenai kesesuaian lahan dan rekomendasi pemupukan perlu dilakukan untuk memberikan informasi kepada petani. Rekomendasi budidaya jeruk di Payo menjadi pedoman pengembangan tanaman jeruk di masa depan. Kegiatan ini bertujuan menyampaikan rekomendasi budidaya tanaman jeruk berdasarkan kesesuaian lahan dan pemupukan, dengan harapan dapat berkontribusi pada pembangunan pertanian berkelanjutan. Kegiatan dilaksanakan di Nagari Payo, Kota Solok, meliputi analisis kesesuaian lahan dan agroklimat berdasarkan data primer dan sekunder, analisis sifat fisik dan kimia tanah untuk rekomendasi pemupukan, serta sosialisasi budidaya jeruk kepada masyarakat. Hasil analisis menunjukkan Payo cocok untuk penanaman jeruk, dengan varietas yang direkomendasikan seperti Keprok Batu 55, Keprok Brastepu, Keprok Garut, Keprok Tejakula, dan Siam Pontianak. Namun, kesuburan tanah rendah sehingga memerlukan perbaikan melalui pengapuran, pemberian amelioran, serta pemupukan organik dan anorganik. Evaluasi kegiatan menunjukkan petani antusias dan memahami informasi yang diberikan. Hingga tiga bulan setelah kegiatan, seluruh bibit yang ditanam tumbuh dengan baik.

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.
