PENGARUH DOSIS ARANG AKTIF TERHADAP PERKECAMBAHAN EMBRIO SOMATIK KEDELAI (Glycine max L.)
Get PDFSoybeans (Glycine max L.) are a type of leguminous food crop that is important as a source of protein and vegetable oil, making them a good potential for human growth. Efforts that can be made to increase production and productivity while reducing imports and soybean development include the assembly of superior varieties through tissue culture, with regeneration through somatic embryogenesis. Somatic embryos that have been produced are matured to obtain seedlings by adding activated charcoal. This research aims to determine the effect and the appropriate dosage of activated charcoal for the germination of somatic embryos of soybeans. The research was conducted in the Tissue Culture Laboratory of the Faculty of Agriculture, Andalas University, Padang, from May to August 2023. The research was arranged in a completely randomized design (CRD) with five treatment levels of activated charcoal dosage, namely 1, 1.5, 2, 2.5, and 3 g/l. The data were analyzed using a 5% level F test, and if the calculated F was greater than the Pr(>F), it was followed by a post hoc test using Duncan's Multiple Range Test (DMRT) at a 5% significance level. The results of the research show that the addition of activated charcoal to the media can germinate somatic embryos of soybean plants. In the media containing 2 g/l of activated charcoal, seedlings emerged at 27.15 days after sowing (DAS), and 96.67% of somatic embryos germinated.

PENGENDALIAN HAMA KUMBANG TANDUK MENGGUNAKAN POC AIR NIRA DAN NANAS PADA TANAMAN KELAPA SAWIT DI DESA BINANGA DUA KABUPATEN LABUHAN BATU SELATAN
Get PDFThis research aims to test the effectiveness of using liquid organic fertilizer (LOF) from sap and pineapple water in controlling horn beetle pests (Oryctes rhinoceros) on oil palm plants in private plantations in Tandikat hamlet, Silangkitang. The approach used was a Randomized Block Design (RBD) with four treatments, namely N0 (control), N1 (100% pineapple starch), N2 (500 grams of pineapple + 1 liter LOF of palm juice), and N3 (500 grams of pineapple + 2 liters of LOF sap water) each repeated four times. The parameters observed included the number of horn beetles caught and those that died. The results of the analysis of variance showed that the significance value of the treatment was <0.05, indicating that there was a real effect of the treatment on the number of horn beetles caught and killed. Duncan's Multiple Range Test (DMRT) further test indicated that the N0 treatment was significantly different from the N2 and other treatments. N2 treatment proved to be the best treatment, showing high effectiveness in controlling horn beetle pests. The conclusion of this research is that the use of LOF from pineapple and palm juice is significantly effective in controlling horn beetle pests on oil palm and is an environmentally friendly alternative to the use of chemical pesticides.Keywords: pests; horn beetles; liquid organic fertilizer; pineappl

PENGARUH PUPUK KANDANG SAPI DAN BERBAGAI JARAK TANAM TERHADAP PERTUMBUHAN DAN HASIL BAWANG DAUN PADA TANAH GAMBUT
Get PDFScallions ( Allium fistulosum L.) are a horticultural crop commodity that is worthy of intensive development in Indonesia, especially in Pontianak, West Kalimantan Province. Peat soil has great potential for the development and cultivation of spring onions. Efforts that can be made to overcome the very low availability of nutrients are cow manure. One cultivation technique that can be used to increase leek production is by adjusting plant spacing. This research was carried out on research land located on Jalan Sungai Raya Dalam, Alam Mulia Housing Complex starting on 15 September – 2 November 2023. This research aims to obtain the best dose of cow manure for the growth and yield of leek plants on peat soil and to obtain the best planting distance for the growth and yield of leek plants on peat soil. This research was carried out using a field experimental method with a Split Plot Design pattern , namely: The first factor is the distance between the plants for the main plot: j 1 = 20 cm x 20 cm, j 2 = 20 cm x 25 cm and j 3 = 20 cm x 30 cm. The second factor is cow manure as a sub plot: p 1 = 10 tonnes/ha, p 2 = 20 tonnes/ha and p 3 = 30 tonnes/ha. The observation variables consist of: Root Volume, Plant Dry Weight, Number of Leaves/clump, Plant Height, Number of Saplings/clump and Fresh Weight of the plant. From research that has been carried out, the interaction of using a planting distance of 20 x 25 cm and 10 tonnes/ha of cow manure shows the best growth and yield of leek plants on peat soil

Get PDFCocoa is a plant that is quite important for the national economy. However, in the production process there are several obstacles faced, such as the presence of weeds. Therefore, control measures need to be taken. An effective way to control weeds is to use herbicides. One of the herbicides that can be used is the herbicide isopropyl amine glyphosate 555 g/l. The aim of the experiment was to test the effect of the herbicide for weed control in cocoa cultivation. The experiment was carried out in Padang Pariaman Regency, West Sumatra Province from August to December 2020. The design used was a Randomized Block Design consisting of 7 treatments and 3 replications. Isopropyl amine glyphosate herbicide treatment 555 g/l with doses of 0.75, 1.00, 1.25, 1.50, 1.75 l/ha, manual weeding and control. The research results show that: (1) The herbicide isopropyl amine glyphosate 555 g/l can generally control weeds in cocoa cultivation for up to 12 weeks after application; (2) The effective dose to control weeds in cocoa cultivation is 0.75 – 1.50 l/ha because it has relatively the same results as manual weeding and a dose of 1.75 l/ha; (3) Isopropyl amine glyphosate herbicide 555 g/l with a dose range of 0.75 – 1.75 l/ha until observation 6 weeks after application did not show any symptoms of poisoning on cocoa plants. Keywords : cocoa, efficacy, herbicide, weed INTISARIKakao merupakan salah satu komoditi pertanian yang cukup penting bagi perekonomian nasional.

KETERKAITAN TEKNIK BUDIDAYA MANGGA DENGAN PENDAPATAN PETANI (SUATU KASUS PADA PETANI MANGGA MAJALENGKA DAN CIREBON)
Get PDFWest Java is one of the provinces that has potential for mango cultivation because it has a climate that is suitable for this plant. However, in 2023 there will be a decline in mango production, followed by an increase in the level of mango consumption in Indonesia, which is indicated to be influenced by the way farmers cultivate mango plants. The aim of this research is to identify farmer characteristics and relate mango cultivation techniques to farmer income in two mango production centers in West Java, namely Majalengka and Cirebon. The research method used is descriptive statistics and non-parametric tests. Respondent selection used a two-stage stratified sampling technique. The sample for this research was 258 mango farmers in Majalengka and Cirebon. The research results show that the majority of mango farmers in Majalengka and Cirebon have a productive age range of 45 - 60 years with an elementary school education level and their main job is as mango farmers. Meanwhile, judging from the cultivation techniques, the majority of mango farmers in Majalengka and Cirebon plant mangoes in gardens/fields with the majority of farmers in Majalengka implementing a polyculture planting pattern, while Cirebon is more dominant in implementing a monoculture planting pattern with the gedong gincu variety as the main variety. Then, the majority of mango farmers in Majalengka and Cirebon have implemented off season technology in their mango cultivation activities. Mango farmers who have a risk-averse nature carry out harvesting independently and control pests. The majority of mango farmers use pesticides as a means of controlling pests. Then, there is a significant relationship between planting location, use of off season technology, and pest control and farmer income in Majalengka and Cirebon.Key-words: Mango cultivation techniques, farmer income, planting location, off season technology, pest control
