Abstract

 Nagari Palaluar, Koto VII Subdistrict, Sijunjung Regency has an area of 5,47.17 ha. . The farmer groups in Palaluar Nagari who are partners are the Gelugur Jaya Farmers Group and the Minang Farmers Group. The dominant farming effort was cultivated by the Gelugur Jaya farmer group, namely rice. In rice cultivation, farming communities in this group every planting season always use artificial fertilizers. Even though rice harvested straw can be reused as an alternative source of organic fertilizer. Most of the agricultural waste, namely rice straw, is simply burned so that it can increase global warming. There are quite a lot of weeds in empty land and on the roadside in the Gelugur Jaya farmer group area. However, farmers have never used it as a source of organic material. Then the Minang farmer group built, the dominant farming business was rice and corn and cocoa plants. Cocoa plants produce a lot of waste, that is, cocoa skin waste is left piling around the land. Therefore it is necessary to process agricultural wastes. The objectives of this PKM program are (1) to increase the knowledge of partner group farming communities about the potential for sugar weeds and agricultural waste as alternative organic fertilizers in reducing the use of artificial fertilizers (2) provide examples of the application of rice cultivation techniques to the use of alternative organic fertilizers, namely weeds and agricultural waste to reduce the application of artificial fertilizers and increase the yield of rice crops. The method of carrying out activities is carried out by lecture, question and answer, demonstration, training (practice), assignment, mentoring and evaluation. The results expected from the implementation of the program are: (1) farmers' knowledge will increase about the importance of making and the potential of sugar weeds and agricultural waste as a source of alternative organic fertilizers to reduce the application of artificial fertilizers and increase rice production. (2) the farming community of the partner group is willing and able to imitate the application of rice cultivation techniques by utilizing sugar weeds and agricultural waste as an alternative organic fertilizer. Keywords : kirinyuh, agricultural waste, organic fertilizer, rice production

Abstract

Tanaman cabai merah keriting (Capsicum annuum L) var lado F1 merupakan komoditi unggulan di Indonesia khususnya di Minangkabau. Masyarakat Minang terbiasa dengan makanan yang dimasak dengan menggunakan cabai. Sementara produksi cabai sering mengalami kegagalan oleh karena beberapa faktor termasuk mahalnya harga pupuk yang dijual di pasaran. Petani sering merugi karena tidak seimbangnya antara pendapatan dan biaya pupuk tanaman cabai. Salah satu inovasi agar bisa membantu petani dalam menghemat biaya pupuk dengan membuat pupuk organik sendiri salah satunya dengan memanfaatkan limbah pasar, limbah yang diproduksi dari pasar tersebut sering tidak dimanfaatkan dan hanya menumpuk pada tempat sampah. Sementara limbah organik bisa dimodifikasi sebagai bahan dasar untuk pembuatan pupuk organik cair (POC) yang bisa dimanfaat untuk semua jenis tanaman termasuk tanaman cabai merah keriting varietas lado F1. Tujuan penelitian adalah untuk mendapatkan data dan melihat efektifitas POC dengan bahan dasar limbah organik pasar terhadap pertumbuhan tanaman cabai merah keriting varietas lado F1. Metode yang digunakan adalah eksperimental rancangan acak kelompok dengan 5 faktor perlakuan dan 5 ulangan sehingga terdapat 25 sampel percobaan dengan dosis POC sebagai berikut : A sebagai kontrol, B dosis 20 %, C dosis 30%, D dosis 40 % dan E dosis 50 %. Dari penelitian yang telah dilaksanakan didapatkan hasil bahwa dosis POC 50 % limbah organik pasar memberikan pengaruh yang signifikan terhadap variabel jumlah daun (114,80 helai), jumlah buah dan bobot buah (26,60 buah) cabai merah keriting (105,60 gram).

Abstract

Shallots (Allium ascalonicum L.) is a vegetable commodity that is prioritized for development because it has high economic value. Some of the problems that arise in cultivating shallots include the high price of fertilizer and less fertile soil. An alternative to solving these two problems is by using compost. One of the plants that can be used as compost is the kirinyuh plant (Chromolaena odorata L.). Kirinyuh compost can improve soil chemical quality and plant growth and yield. This research aims to determine the dosage of kirinyuh compost for the growth and production of shallot plants. Carried out on the experimental land of the Department of Agroindustry, Padang State University, Sijunjung campus with an altitude of ± 450 meters above sea level, in February-June 2023. The research used a Randomized Block Design  with 4 treatments and 6 replications. The levels of treatment given are as follows: K0 Without treatment (control), K1 100 g/polybag, K2 300 g/polybag, K3 600 g/polybag. The parameters observed were plant height (cm), number of leaves (strands), number of bulbs (fruit), wet weight of shallot plants (g). The results of this research had a significant effect on the height of shallot plants with an average height of 39.029 cm (K3), and had no significant effect on other observed parameters. Keywords: kirinyuh, growth, production, shallots

Abstract

Watermelon is a horticultural commodity that is highly favored by the people of Indonesia and has quite high economic value because it tastes sweet and has a lot of water content. One of the obstacles in watermelon cultivation is improper cultivation techniques so that production is not optimal. This study aims to determine the efficiency of pruning watermelon plants and applying KCl fertilizer to watermelon production. This study was arranged based on a completely randomized design (CRD) with two treatment factors, namely A (pruning) consisting of A0 (pruning main branches), A1 (pruning primary branches) and A2 (pruning secondary branches), treatment factor B (KCl Fertilizer) consists of B0 (100 g/plant), B1 (150 g/plant) and B2 (200 g/plant). The parameters observed in this study were plant height, number of nodes, first flower appearance, fruit circumference per sample, fruit weight per sample and total soluble solid content. Based on the results of research on the efficiency of pruning branches and applying KCl fertilizer in the generative phase on the production of the watermelon plant (Citrullus vulgaris S.) of the Baginda F1 variety that has been carried out, it can be concluded that pruning primary branches and applying a dose of 200 g/plant of KCl fertilizer gives good results against variables of fruit circumference and fruit weight as well as pruning of primary branches also gave the best results on the total soluble solit (TSS) value of watermelon. This study was analyzed statistically using analysis of variance (ANOVA) followed by the Duncans New Multiple Range Test (DNMRT) at 5% level. Keywords: Branch Pruning, KCl Fertilizer, Watermelon

Abstract

Compost is the result of organic fermentation that enriches soil nutrients naturally and is environmentally friendly. Banana peels have the potential to compost raw materials that are rich in nutrients, so far they are often wasted. Banana peel compost decomposed organic matter with the microorganism Trichoderma harzianum to improve the quality of banana peel-based compost. Its main purpose is to speed up the decomposition process and improve the nutritional quality of compost. This research was used to make compost from banana peels, with the addition of Trichoderma harzianum. The result is banana peel compost with nitrogen (N) content of 2.07% and potassium (K) of 5.02%, according to organic fertilizer quality standards in Indonesia. The population of microorganisms in compost varies, peaking at 16.4 x 107 cfu/gram and low at 11.6 x 108 cfu/gram. During composting, there is a significant change in pH. Initially, the pH is close to neutral (6.8), but drops dramatically to 4.9 by day 5. After this period, the pH increases again until it reaches 7.0 from day 16 to day 21. The results showed that composting banana peel waste with the addition of Trichoderma harzianum was effective in improving compost quality and producing products that conform to standards. Trichoderma harzianum can speed up the decomposition process, improve nutrient quality, and produce compost with an appropriate C/N ratio. Keywords: decomposition, compost, banana peel waste, Trichoderma harzianum

Abstract

In the propagation of Kepok Tanjung Bananas, many use natural vegetative propagation, so that the seeds obtained are in small quantities and require a long time, while artificial vegetative propagation has advantages, among others, in a short time it can produce large amounts of uniform seeds. Propagation of seedlings from weevils can take advantage of the remaining felled stump so that the cost is relatively cheap. By administering some natural Growth Regulatory Substances (PGR) can affect the success of vegetative propagation using weevils. The role of PGR, among others, is to regulate the speed of growth and integrate plant tissues to form a plant. The research objective was to obtain the best shoot growth from the vegetative propagation of the banana weevil (Musa paradisiaca L.) kepok tanjung variety by administering some natural Growth Regulatory Substances (PGR). This study used an experimental method using a completely randomized design (CRD), with treatments namely B0: Control; B1: bamboo shoot extract; B2: shallot extract; B3: coconut water. Parameters observed were the age of shoot emergence, number of shoots, shoot length, age of transplanting or transplanting. The results of the test of several natural Growth Regulatory Substances (PGR) for vegetative propagation of the banana weevil (Musa paradisiaca L.) of the Kepok Tanjung variety that have been carried out can be concluded that the application of several natural PGR, coconut water provides higher shoot growth with a total of 5 shoots, shoot length was 92.5 cm, number of leaves was 2.60 and the age of transplanting was 39.8 DAP, while PGR of bamboo shoots could accelerate the age of shoot emergence on day 28.8. Keywords:Banana Weevil, Vegetative, Natural PGR

Abstract

Tempe is a typical Indonesian food that comes from fermenting soybeans with the fungus Rhizopus sp. Tempe is known to have good nutritional value because of the content contained in soybeans themselves and other microorganisms that appear as a result of the tempe fermentation process. The fermentation process increases the activity of bacteria in tempe which are beneficial for digestion, one of which is lactic acid bacteria. This research aims to see the differences morphological forms  and genomic of lactic acid bacteria produced by tempe wrapped in banana leaves and tempe wrapped in plastic. The differences in fermentation that occurred in tempe wrapped in banana leaves and those wrapped in plastic resulted in differences in lactic acid bacteria type. Based on the isolation of bacteria on Mann de Rogosa Sharpe Agar medium, 15 isolates of lactic acid bacteria were produced, with general morphological forms of bacilli and coccus. Then, genomic identification was carried out using the PCR. The phylogenetic tree built based on the 16S rRNA gene sequence can show the relationship between LAB diversity at the species level, but cannot differentiate LAB from the strain level.
