Abstract

Bawang putih (Allium sativum L.) adalah sayuran yang banyak memberikan keuntungan dan manfaat karena mempunyai nilai ekonomi yang tinggi. Kebutuhan konsumsi bawang putih semakin meningkat sejalan dengan pertambahan jumlah penduduk, namun peningkatan ini belum diimbangi oleh peningkatan produksi karena banyak kendala antara lain serangan organisme pengganggu tanaman. Penggunaan entomopatogen sebagai agens pengendali hayati merupakan salah satu cara yang dapat dilakukan untuk menghindari dampak negatif bahan kimia terhadap lingkungan. Agens hayati tersebut meliputi organisme yang bersifat predator, parasit, parasitoid, dan patogen. Beberapa organisme yang dapat bertindak sebagai agens hayati meliputi hewan vertebrata, nematoda, serangga, virus, bakteri, dan jamur. Metode yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok Non Faktorial dengan masing-masing perlakuan B0 (0 gr Beauveria bassiana), B1 (3 gr Beauveria bassiana /L air), B2 (6 gr Beauveria bassiana /L air), B3 (9 gr Beauveria bassiana /L air), dan B4 (12 gr Beauveria bassiana /L air). Hasil penelitian menunjukkan bahwa perlakuan Beauveria bassiana menunjukkan pengaruh yang nyata terhadap persentase serangan seranga yaitu 0,06% dan intensitas serangan yaitu 0,03%. Perlakuan terbaik terdapat pada B4 (12 gr B.bassiana/L air). Kata Kunci: Bawang putih, Beuveria bassiana, Spodoptera litura

Abstract

The use of a mixture of rhizome extracts of red ginger, turmeric, and kencur to control armyworms (Spodoptera litura F.) is an important prospect in increasing the yield of sweet potato crops, because plant-based pesticides can be used in single or mixed forms. The study aimed to determine the influence of various mixed effects of different concentrations of extracts of several rhizomes on the mortality of Grayak caterpillar pest (Spodoptera litura F.) on sweet potato plants (Ipomoea batatas L.). As well as determining the concentration of rhizome extract mixture that is more effective in controlling Grayak caterpillar pests (Spodoptera sp.) on sweet potato plants (Ipomoea batatas L.). This study used a method with a Group Random Design (RAK) consisting of 5 treatments and 5 replicates. The treatment is: 1. Control (sterile water application), 2. A mixture of red ginger, turmeric, and kencur rhizome extracts 40%, 50%, 60%, 70%, 80%, 90% through food (Stomach poison). The experiment was arranged in a complete randomized design of four replicates each using instar 2 larvae of Spodoptera sp. as many as 280 heads. Research Results The observation results showed that there was an influence of each concentration tested on the pest Spodoptera sp. through food (Stomach poison) against the larvae of the second instar where the level of attack caused in the instar is very high, so the concentration used is 40%-90%. All concentrations showed a real effect on the larvae of the two instars, at a concentration of 40% a mortality rate of 11.50%, and the highest concentration was 90% with a mortality rate of 80%..

Abstract

This study aims to determine the effect of pruning on the growth and yield of cucumber variety Mercy. This research was organized using a Randomized Group Design (RAK) with treatments, namely: No pruning (P0), pruning shoots on the main stem (P1), pruning shoots of all lateral branches after the third internode (P2) and pruning 2 lateral branches that appear first after the 3rd internode (P3) with 5 replications. The variables observed in this study consisted of; plant length, number of leaves, total number of fruits, number of harvestable fruits, harvestable fruit length, harvestable fruit diameter, and harvestable fruit weight. Data were analyzed using the F test and if there were significant differences followed by the 5% BNT test. The results showed that the treatment without pruning (P0) was able to produce a better number of fruits than the pruning treatment, but the number of fruits produced was of poor quality. The best plant results were found in the shoot pruning treatment on the main stem (P1) because it was able to increase the number of leaves 24.19% compared to no pruning treatment (P0).

Abstract

Cucumber (Cucumis sativus L.) is one of the vegetable plants that has many benefits, namely besides being able to be used as vegetables, fresh vegetables, salads or pickles, cucumbers are also beneficial for health because the nutritional value of cucumbers is quite good as a source of minerals and vitamins. Efforts to increase cucumber plant production can be influenced by many factors, one of which is fertilization. Fertilization is a determining factor in efforts to increase the availability of nutrients for plants, thus the expected impact of fertilization is not only to increase the yield per unit area but also to be efficient in the use of fertilizers. The method in this research is Non Factorial Randomized Group Design with four treatments and six replications, namely A0 (Control), A1 (Cow dung manure dose of 3 kg / polybag), A2 (Cow dung manure dose of 5 kg / polybag) and A3 (Cow dung manure dose of 7 kg / polybag). The results showed that the treatment of cow dung manure gave a significant effect on the parameters of plant height and fruit weight. The best treatment is found in A3, which is the application of cow dung manure at 7 kg/polybag.
