Abstract

Pests, pathogens and weeds are enemies of plants that cause a decrease in crop productivity to a decrease in production which leads to a decrease in farmers' income. So far, farmers have controlled the population of these plant pests using chemical pesticides because they are effective, cheap and fast. However, the use of these chemical pesticides has a negative impact on the environment because the chemical residues will settle in the soil and can contaminate agricultural produce, water and air, which can have an impact on human health. exDNA technology can be an alternative to biopesticides and plant vaccines to control pests, weeds and pathogens. Extracellular DNA referred to in this context is DNA outside the function of genetic inheritance. Recently it was discovered that the functional role of new DNA is that it can produce growth inhibitory effects in specific organisms (organisms within one species) and acts as an elicitor, inducing a defense system in organisms outside the species of origin exDNA (non-self). Here, the authors provide an overview of plant responses to extracellular DNA to its application in agriculture as a technology for plant protection. Keywords: biopesticide; extracellular DNA; non-self exDNA; self-exDNA; plant vaccines

Abstract

ABSTRACT Sweet corn is a horticultural commodity that has a high carbohydrate source. The need for this commodity continues to increase every year. But, on the other hand production is still low. Therefore, efforts are needed to increase sweet corn production. One effort that can be done is to utilize nuclear technology. Utilization of nuclear techniques in maize plants, among others, is to improve the genetic traits of varieties through mutations with radiation. The aim of this study was to obtain sweet corn liness that have the character of the yield of sweet corn plants irradiated by gamma rays. The study was conducted on land owned by PT. Pertani from May to September 2019. The research method used was an experimental method with factorial randomized block design. The first factor is sweet corn line consisting of 5 levels, namely G1 (MS-02), G2 (MS-04), G3 (MS-06), G4 (MS-07), G5 (MS-08). The second factor is the dose of gamma ray radiation which consists of 4 levels, namely M0 (0 gray), M1 (100 gray), M2 (200 gray), M3 (300 gray), so there are 20 treatments. Each treatment was repeated 2 times. The results showed that sweet corn lines with gamma ray irradiation had a significant effect on all parameters observed. In general, the treatment of G1M1 (MS-02 lines + 100 gray gamma ray dose) gave the best effect on the yield parameters 3.49 kg / plot, the weight of the cob with a cobe of 214.25 grams, the weight of the cob without a kelobot of 154.70 grams , the diameter of the cob without the kelobot is 4.43 cm, and the length of the cob without the kelobot is 16.88 cm. Whereas the treatment of G5M0 (lines MS-08 + dose of gamma rays without radiation (0 gray)) gave the best effect on the diameter of the cob with a 4.98 cm cobe and the length of the cob with a 27.73 cm cobe And the treatment of G5M3 (lines MS-08 + gamma ray dose of 300 gray) gave the best effect on the sugar content parameter, 18,500Brix. Keywords: MS-Unsika lines, sweet corn, irradiation, yield test.

Abstract

Bibit unggul berkualitas merupakan faktor yang mempengaruhi produksi dan hasil jamur merang. Penelitian ini bertujuan untuk mendapatkan jenis bibit yang memberikan pertumbuhan dan hasil jamur optimum pada media proporsi substitusi serbuk sabut kelapa. Penelitian dilaksanakan di Laboratorium Fakultas Pertanian Universitas Singaperbangsa Karawang dan di uji pada kumbung yang berlokasi di Desa Muktijaya  Kecamatan Cilamaya Kulon Kabupaten Karawang. Pada bulan Oktober 2021-Januari 2022. Metode penelitian yang digunakan adalah Rancangan Acak Kelompok (RAK) faktor  tunggal dengan 3  ulangan. Terdapat 10 perlakuan, yaitu A (F4 FP Putih), B (F4 FP Semi), C (F4 FP005), D (F4 FP006), E (F4 FP017), F (Maja Putih), G (Maja Semi), H (Wiji Putih), I (Wiji Semi) dan J (Merdeka Putih). Pengaruh perlakuan dianalisis dengan analisis ragam dan apabila uji F taraf 5% signifikan, untuk mengetahui perlakuan yang terbaik dilanjutkan dengan uji lanjut DMRT (Duncan Multiple Range Test). Pada taraf 5%. Hasil penelitian menunjukkan bahwa terdapat pengaruh nyata perbedaan bibit genotipe harapan F4 Faperta Unsika dan bibit Komersil terhadap pertumbuhan dan hasil jamur merang (Volvariella volvacea). Perlakuan A (F4 FP Putih) memberikan hasil tertinggi bobot konversi satu kumbung  yaitu 108.80 kg, jumlah tubuh buah 8,94 buah, bobot tubuh buah 9,09 g dan bobot  total perpetak 86,35 g dan isolat hibrida F4 FP005 memiliki nilai tertinggi pada bobot konversi satu kumbung yaitu 80,38 kg, jumlah tubuh buah 6,78 buah, bobot tubuh buah 12,81 g dan bobot total perpetak 63,79 g

Abstract

Shallots (Allium ascalonicum L.) is a crucial vegetable commodity because it has a high nutritional content and the demand for shallots in Indonesia is increasing. Efforts to meet the demand for shallots in Indonesia are the use of high yielding varieties in order to spur increased productivity of shallots in the lowlands. This study aims to obtain the best results from the analysis of the morphological character of eight red onion accessions in rice fields in Karawang district. The research was carried out in the experimental field of the Faculty of Agriculture, Singaperbangsa Karawang University, which is located in Pasirjengkol Village, Majalaya District, Karawang Regency. The research method used a single factor Randomized Block Design (RAK). There were 8 treatments and repeated 4 times, so there were 32 experimental plots. Data were analyzed using analysis of variance and further test with DMRT (Duncan Multiple Range Test) at 5% level. The results of this experiment showed that there was a significant effect of the appearance of the morphological characters of shallot accessions on the growth components (plant height, number of leaves, and number of bulbs). The BM5 (Bima) treatment gave the best results on plant height of 33.25/cm, and BR6 (Berlind) treatment gave the best results on the number of leaves of 42.40/strand, and the number of tubers of 16.50/ clove.

Abstract

One type of land found in the swamp ecosystem is acid sulfate land. This land has the potential to be developed into agricultural land, especially rice plants. However, it is classified as problematic land because it has negative characteristics and is less fertile. Sulphidic materials are characteristic of acid sulfate soils where pyrite is abundant. The unique properties of pyrite are highly dependent on water conditions and come from marine deposits, namely mineral or organic soils that contain a lot of S which is easily oxidized and have soil acidity that tends to be very low. This research was carried out from June to October 2021 at Sungai Rangas, West Martapura District, Banjar Regency, and the Laboratory of the Department of Soil, Lambung Mangkurat University, Banjarbaru, South Kalimantan. The method used in this study is the design in this study was compiled using a randomized block design (RBD) with a split-plot design. The first factor studied was the type of compost (A) as the main plot consisting of three treatment levels: a1 = rice straw compost, a2 = coffee grounds compost, a3 = oyster mushroom baglog waste compost while the second factor was the dose of compost (B) as a child. The plot consisted of two treatment levels: b1= 0 t ha-1, b2= 20 t ha-1 divided into four experimental blocks so that 24 experimental units were obtained. The results showed that the application of compost waste rice straw, coffee grounds, and baglog of oyster mushrooms at a dose of 20 t ha-1 can increase soil pH and reduce soil soluble Fe and Al-soluble in acid sulfate soils.
