Abstract

Plants have an important role in the development of human civilization. Human civilization progresses along with the development of the agricultural system and vice versa. Therefore humans have been trying to improve cultivated plants for thousands of years by trial and error. Traditionally, mankind have improved plants through repeated selection. However, the human population is increasing so rapidly that it necessitates a doubling of the increase in world food production. The program is constrained by the fact that we cannot increase arable land. So one solution is through biotechnology which is expected to produce more food without demanding an increase in agricultural land. At present, the application of biotechnology in agriculture can be done by genetic engineering such as genetic transformation and gene editing which are almost entirely aimed at forming transgenic plants. One of the developments in biotechnology that has been widely used is GMO (Genetically Modified Organism) or plants that have been genetically modified or are popularly known as transgenic plants. Genetic modification of plants has become the most promising approach for increasing crop yields, providing nutrients, exploiting stressed land, overcoming the energy crisis, and for producing cost-effective biopharmaceuticals.

Abstract

Selada merupakan sayuran semusim yang dapat tumbuh dengan baik pada musim hujan maupun musin kemarau. Tanaman ini termasuk sayuran daun yang berumur pendek dan dapat ditanam di dataran tinggi atau dataran rendah. Penelitian ini dilaksanakan pada bulan Maret sampai April 2023 di Dusun Jaro, Desa Rejomulyo, Kecamatan Kras, Kabupaten Kediri, Propinsi Jawa Timur. Beriklim tropis pada ketinggian ±75 m diatas permukaan laut, dengan rata-rata suhu udara 280 C. Ditanam pada tanah tegal dengan jenis tanah aluvial. Penelitian ini menggunakan Rancangan Acak Lengkap ( RAL ) Faktorial dengan dua faktor. Faktor pertama adalah macam varietas dengan 2 level, dilambangkan dengan (V). Faktor kedua adalah dosis pupuk bokashi dengan 5 level, dilambangkan dengan (D). Perlakuan diulang sebanyak 3 kali dengan 30 satuan percobaan. Setiap plot terdapat 10 tanaman dengan 5 tanaman sampel. Data yang diperoleh diuji dengan sidik ragam ANOVA. Jika terjadi interaksi antar perlakuan akan diuji lanjut menggunakan DMRT 5%. Jika tidak terjadi interaksi, maka perlakuan tunggal akan diuji lanjut menggunakan BNT 5%. Hasil kombinasi perlakuan macam varietas dengan perlakuan dosis pupuk bokashi menunjukkan hasil interaksi yang nyata pada variabel pengamatan volume akar dengan kombinasi perlakuan V2D4 (Varietas Red rapid + dosis pupuk bokashi 20 ton/ha) merupakan perlakuan yang paling efektif meningkatkan volume akar. Perlakuan tunggal macam varietas menunjukkan pengaruh sangat nyata pada variabel pengamatan tinggi tanaman, jumlah daun, dan panjang akar. Hasil penelitian menunjukkan bahwa perlakuan D4 (dosis 20 ton/ha) merupakan perlakuan dosis pupuk bokashi yang efektif dan efisien dalam meningkat pertumbuhan dan hasil tanaman selada merah.

Abstract

his observation aims to determine the level of effectiveness of the organic pesticide garlic and tobacco against the control of whitefly pests (Bemisia tabaci) and production of tomato (Lycopersicum esculentum) which was conducted from 3rd October until 20th December 2022 at UNISKA Kediri field laboratory. The study was conducted at the UNISKA Kediri field laboratory with a known pH of 5 with sandy loam soil type was conducted from October 03, 2022 to December 20, 2022. The research method used a non-factorial Randomized Group Design. The factors is type of vegetable pesticides (garlic and tobacco) with each consisting of four concentration levels of 0%, 20%, 40% and 60% so that there are 8 kinds of combination, carried out as many as 4 replicates and 3 samples of tomato plants were taken and used 96 sample of plants and about 1000 whitefly. After data was obtained, a varians analysis was carried out if there was continued with BNT 5% test. From the observation, it is known that the types of pesticides have a significant effect on the mortality rate of whitefly pests, while the concentration have a very significant effect on the mortality rate of whitefly with abest dose is 60% , but there is no interaction between the two single factors. In addition, the application of the organic pesticides does not have an effect on the growth and production of tomato, this is because organic pesticide isn’t type of nutrients that can help the growth and production on tomatoes

Abstract

The research was conducted from May to December 2023 at the UNISKA Kediri Field Laboratory. The aim of the research was to determine the interaction of giving organic fertilizer from rabbit droppings and inorganic fertilizer on tomato growth and production. The materials used are two types of rabbit manure, namely solid and liquid, inorganic fertilizer NPK 16:16:16 and tomato plant seeds. RAKF research method (Randomized Group Factorial Design). The first factor is rabbit manure fertilizer, consisting of two levels, the second factor is inorganic fertilizer consisting of 4 levels, so that 8 treatment combinations are obtained. After the data is obtained, an analysis of variance is carried out and continued with BNT 5% if there is a real influence on a single factor and a DMRT test is carried out if an interaction occurs. It was found that solid rabbit manure had a very significant effect on the number of leaves, plant height, stem diameter, number of fruit and fruit weight. Inorganic fertilizers have a significant effect on the number of leaves, plant height, stem diameter, number of fruit and fruit weight. The best rabbit manure treatment is solid rabbit manure (K1) and the best inorganic fertilizer treatment is NPK 16:16:16 fertilizer treatment with doses of 5 grams and 7.5 grams.

Abstract

Kacang hijau (Vigna radiata L.) menempati posisi ketiga sebagai sumber pangan kacang-kacangan terpenting di Indonesia dan berpotensi dikembangkan pada berbagai agroekosistem. Produktivitas kacang hijau di tingkat petani masih tergolong rendah, salah satunya disebabkan oleh pengelolaan hara yang belum optimal, khususnya penggunaan pupuk organik dan pupuk fosfat. Penelitian ini bertujuan untuk mengetahui respon pertumbuhan dan produksi tanaman kacang hijau (Vigna radiata L.) terhadap pemberian macam pupuk kandang dan dosis pupuk fosfat. Penelitian dilaksanakan di Desa Punjul, Kabupaten Kediri, pada bulan Desember 2024 sampai Maret 2025, dengan menggunakan rancangan acak kelompok (RAK) dua faktor, faktor pertama adalah macam pupuk kandang (K1: pupuk kandang sapi, K2: pupuk kandang kambing, K3: pupuk kandang ayam) dan faktor kedua adalah dosis pupuk fosfat SP-36 (P1: 100 kg/ha, P2: 200 kg/ha, P3: 300 kg/ha). Hasil penelitian ini menunjukkan adanya interaksi aritara macam pupuk kandang dan dosis pupuk fosfat pada tinggi tanaman, jumlah daun, dan jumlah cabang produktif. Perlakuan pupuk kandang berpengaruh nyata pada jumlah polong, bobot polong basah, dan bobot biji kering per tanaman. Sementara itu, perlakuan dosis pupuk fosfat SP-36 berpengaruh nyata pada bobot biji kering per tanaman, dan bobot 100 biji per petak.
