Abstract

Research was conducted in Limau Manis, Padang City of West Sumatra. Theexperimental design used was a non-factorial randomized block design. Job’s tears used in this study is a cultivar of beras. The research objective was to determine the effect of various levels of population density on job’s tears growth in sub-optimal area. The density of the population used in this study is that A1 = 62,500 plants / ha (spacing of 40 x 40 cm), A2 = population of 50,000 plants / ha (spacing of 50 x 40 cm), A3 = 40,000 plants / ha (spacing 50 x 50 cm), A4 = 33,333 plants / ha (spacing 50 x 60 cm), A5 = 28,571 plants / ha (spacing 50 x 70 cm), A6 = 25,000 plants / ha (spacing 50 x 80 cm), A7 = 22,222 plants / ha (spacing 50 x 90 cm), and A8 = 20,000 plants / ha (spacing 50 x 100 cm). The results showed that the density of the plant population that was too dense had an effect on the decline in several growth components but showed the highest average ILD value. Whereas treatment with population density that was not too high or by using spacing that was tenuous gave the best effect on the variables of plant height, number of tillers and number of leaves. Further observations are needed to determine the effect of the treatment given on theyield components.

Abstract

Bunga matahari merupakan komoditi yang memiliki potensi untuk dikembangkan sebagai bahan baku penghasil minyak nabati karena mengandung vitamin E yang cukup tinggi. Tanaman ini memiliki daya adaptasi yang luas dan membutuhkan daerah dengan sinar matahari penuh. Walau demikian, hanya varietas tertentu yang mampu untuk tumbuh dan berkembang optimal diberbagai agroekosistem. Sehinga diperlukan suatu informasi mengenai kesesuaian varietas dengan kondisi spesifik suatu lokasi. Penelitian ini bertujuan untuk memperoleh informasi tentang varietas yang adaptif pada lahan bukaan baru di dataran tinggi Alahan Panjang, Kabupaten Solok, Sumatera Barat (1.620 mdpl) berdasarkan pertumbuhan dan hasil yang dicapai. Percobaan dirancang menggunakan Rancangan Acak Kelompok (RAK) dengan 3 kelompok dan 5 taraf perlakuan, yaitu varietas bunga matahari. Varietas meiputi IPB BM 1, Ring of fire, Russian Mammoth, Hoppy Black Dye, Black Russian, dan Kanigara. Varietas Russian Mammoth, Ring of Fire dan Hopi Black Dye memiliki pertumbuhan yang lebih baik apabila dilihat dari keadaptifannya di lokasi penelitian. Sedangkan berdasarkan bobot biji/tanaman, persentase biji bernas, dan bobot 100 butir varietas Russian mammoth memiliki hasil yang terbaik.Sunflower is a commodity that has the potential to be developed as a raw material for producing vegetable oil because it contains high levels of vitamin E. This plant has wide adaptability and requires areas with full sun. However, only certain varieties are able to grow and develop optimally in various agroecosystems. So we need information regarding the suitability of varieties with specific conditions of a location. This study aims to obtain information about varieties that are adaptive to new openings in the highlands of Alahan Panjang, Solok Regency, West Sumatra (1,620 masl) based on growth and yields achieved. The experiment was designed using a Randomized Block Design (RAK) with 3 groups and 5 levels of treatment, namely sunflower varieties. The varieties include IPB BM 1, Ring of fire, Russian Mammoth, Hoppy Black Dye, Black Russian, and Kanigara. The varieties of Russian Mammoth, Ring of Fire, and Hopi Black Dye have better growth when viewed from their adaptability in the research location. Meanwhile, based on the weight of seeds/plant, the percentage of pithy seeds, and the weight of 100 grains the Russian mammoth variety had the best results.

Abstract

Hanjeli is one of the alternative food crops that are high in nutrients, healthful, easy to grow, and adaptable to a wide range of environmental circumstances. Due to the limited understanding of people who believe Hanjeli is a wild plant or weed, usage of this commodity is still quite low in Indonesia. To save and prevent the loss of genetic resources, it is vital to study, inventory, and characterize Hanjeli so that plant breeders can use it to create greater varieties in the future. The goals of this study are to: (1) learn about the existence and types of Hanjeli plants in West Sumatra Province; (2) collect Hanjeli germplasm; and (3) learn about the morphological diversity and level of similarity of Hanjeli plants as a starting point for germplasm conservation of Hanjeli plants in West Sumatra. This study took place in four districts/cities in West Sumatra Province from June to November 2021. This study is carried out using a survey method with purposive sampling. The NTSYSpc2.02i application is used to present morphological data descriptively and for similarity analysis. 69 Hanjeli accessions were discovered throughout the exploration process. Hanjeli grows between 6 to 1575 meters above sea level and can thrive in a variety of environments, including arid ground and regions near water sources (starting on the outskirts of streams to the edges of rice fields). For all characters, the phenotypic similarity study of Hanjeli plants yielded similarity coefficients ranging from 0.67 to 1. At 0.67, the accessions were divided into two groups: 66 accessions in the first group, and 3 accessions in the second group.

Abstract

Kegiatan Pengabdian Ipteks Berbasis Dosen dan Masyarakat (IBDM) telah dilaksanakan bersama mitra Kelompok Tani Harapan Baru yang berlokasi di Kabupaten Solok. Budidaya tanaman hortikultura yang dilaksanakan oleh kelompok tani ini sangat bergantung pada penggunaan pestisida untuk pengendalian hama dan penyakit tanaman nya. Seringkali penggunaan pestisida nya jauh melebihi takaran yang dianjurkan, sehingga produk yang dihasilkannya banyak mengandung residu pestisida. Mereka menyadari bahwa penggunaan pestisida yang berlebihan dapat mengakibatkan gangguan kesehatan dan menurunkan kesuburan lahan. Untuk itu, Kelompok tani Harapan Baru menyatakan ingin menjadi kelompok tani yang ramah lingkungan dengan melakukan praktek budidaya pertanian yang ramah lingkungan. Tujuan utama dari kegiatan ini adalah meningkatkan pengetahuan dan keterampilan petani untuk pembuatan pestisida nabati. Kegiatan yang dilaksanakan terdiri atas persiapan dan sosialisasi kegiatan, pengenalan bahan pestisida nabati, praktek pembuatan pestisida nabati untuk pengendalian hama, dan aplikasi pestisida nabati ke lahan milik petani. Secara umum kegiatan ini dapat berjalan dengan lancar sesuai dengan yang diharapkan. Kelompok tani sudah dapat memilih bahan baku dan cara membuat beberapa jenis pestisida nabati. Pada kegiatan ini telah dihasilkan tiga jenis pestisida nabati yang berasal dari ekstrak daun pepaya yang memiliki metabolit sekunder seperti alkaloid, terpenoid dan flavonoid, ekstrak kulit jengkol yang mengandung senyawa asam jengkolat, saponin, terpenoid, tanin, steroid dan alkaloid, dan ekstrak daun sirsak yang mengandung senyawa annonain dan resin. Ketiga pestisida nabati yang dihasilkan terbukti efektif mengendalikan hama pada tanaman hortikultura, seperti bawang merah, tomat, kubis, dan cabai.

Abstract

One of the factors causing the low productivity of rice in West Sumatra Province is quality seeds, which are still very low. Also, many rice varieties currently used have a low resistance to pests and diseases, particularly the leafhoppers, which currently attack rice in West Sumatra. The National Nuclear Energy Agency (BATAN) is one of the institutions that produce new rice varieties through mutation technology, one of the varieties produced in the Kahayan variety. Kahayan varieties have several advantages over the previous varieties, namely early age, high productivity, and resistance to certain pests and plant diseases. This activity aims to disseminate the breeding of Kahayan rice seeds to breeding farmer groups so that they can fulfill their needs for rice seeds independently. The activity was carried out at the Air Sarasah Farmer Group in Nagari Sungai Batang, Tanjung Raya District, Agam Regency, from November 2019 to March 2020. The activity consisted of disseminating breeding activities, implementing Kahayan rice breeding, and assisting Kahayan rice varieties' breeding. From this activity, farmer groups have been able to better breed rice, according to the operational standards for seed breeding set by the Ministry of Agriculture of the Republic of Indonesia. Also, farmer groups have been able to increase their knowledge of certifying rice seeds. From the results of rice seed breeding, it was obtained that the Kahayan rice seed class Basic Seed (BD) yield was 6.1 tonnes/hectare, which exceeded the national average rice yield, namely in 2018, it was 5.2 tonnes/hectare.

Abstract

Reforestation is an effort to restore, maintain and improve the condition of the land so that it can be used optimally according to its original function. Several steps to realize the reforestation of the residential environment in a narrow area include utilizing the existing land, choosing suitable plants, and providing utmost care. This activity aimed to increase public understanding and knowledge regarding narrow land for reforestation in urban areas. The method used was a direct approach, namely, conducting interviews with the community and holding outreach and direct demonstrations in the field. The result of this empowerment activity was that the communities, especially the residents of Palimo Indah, are very enthusiastic about participating in the greening of the environment. The selected plants consider their multifunctionality for the environment's good, such as the absorption of air pollution and family medicinal plants. The three tree seedlings are useful for reforestation and have economic value, namely the Sungkai plant, Petai tree, and Agarwood sap-producing plant. Planting has been carried out at several location points by collaboration as a form of community empowerment, namely on the park's outskirts and on the riverbanks in the Palimo Indah, Pauh District, Padang.
