Antraknosa merupakan salah satu penyakit utama yang menyerang tanaman cabai merah (Capsicum annuum L.) sehingga dapat menurunkan produktivitas. Penggunaan fungisida nabati dan mikroorganisme dapat mengurangi persentase serangan antraknosa pada cabai merah tanpa menimbulkan dampak negatif terhadap lingkungan. Penelitian ini bertujuan yaitu untuk mengetahui potensi larutan daun mimba dan MOL bonggol pisang dengan dosis yang tepat dalam mengendalikan penyakit antraknosa serta meningkatkan pertumbuhan dan hasil pada tanaman cabai merah. Model penelitian yang digunakan yaitu Rancangan Acak Kelompok Faktorial yang terdiri atas dua faktor yaitu konsentrasi larutan daun mimba (0%, 15%, 30%, 45%) dan konsentrasi MOL bonggol pisang (0%, 15%, 30%, 45%). Hasil penelitian menunjukkan bahwa konsentrasi larutan daun mimba tidak memberikan pengaruh yang nyata terhadap semua peubah yang diamati. Konsentrasi larutan MOL bonggol pisang 45% berpengaruh nyata dalam meningkatkan tinggi tanaman, jumlah daun, jumlah cabang produktif dan bobot buah per tanaman dibandingkan dengan perlakuan kontrol, namun tidak berbeda nyata dibandingkan dengan konsentrasi 30%. Pada penelitian ini tidak terjadi serangan antraknosa terhadap semua tanaman yang diamati pada semua perlakuan, artinya persentase kejadian penyakit dan tingkat keparahan penyakit adalah 0%. Hal tersebut terjadi diduga karena faktor lingkungan yang tidak mendukung untuk perkembangan jamur Colletotrichum sp.Kata kunci: Capsicum annuum, Colletotrichum, mimba, bonggol pisang

This study was conducted at the experiment garden of Agrotechnology Department, DjuandaUniversity, Bogor, from July to September 2018. The study was aimed at assessing the effects ofthe application of nitrogen fertilizer and mung bean sprout extract on the growth and productionof edamame (Glycine max L. Merril) plants. The experimental design used was a factorialcompletely randomized design. The first factor is the dose of N fertilizer with four levels, namelywithout N (0 kg N / ha), a half recommendation of N fertilizer (34.5 kg N / ha), one recommendationof N fertilizer (69 kg N / ha), and one and a half recommendation of N fertilizer (103.5 kg N / ha).The second factor is the concentration of mung bean sprout extract with four levels, namely withoutmung bean sprout extract (0g tauge extract / l water), a half recommendation of mung bean sproutextract (75g tauge extract/ l water), one recommendation of mung bean sprout extract (150g taugeextract / l water) and one and a half recommendation of mung bean sprout extract (225g taugeextract/ l water). The results showed that the dose of N fertilizer significantly affected the widestleaf area. The concentration of mung bean sprout extract significantly affected the number of shootsat 6 and 7 weeks after planting (MST).Keywords: edamame soybean, N fertilizer, mung bean sprout

AbstrakSelada (Lactuca sativa) termasuk kelompok tanaman sayuran daun yang dikenal dimasyarakat. Jenis sayuran ini mengandung zat-zat gizi khususnya vitamin dan mineral yang lengkap untuk memenuhi kebutuhan gizi masyarakat. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk organik rumput laut terhadap pertumbuhan dan produksi Selada (Lactuca sativa L.). Penelitian ini dilakukan pada bulan April -Maret 2014 dan bertempat di lahan penelitian dan laboratorium Budidaya Pertanian, Jurusan Agroteknologi, Fakultas Pertanian, Universitas Djuanda Bogor. Penelitian ini disusun menggunakan rancangan acak lengkap (RAL), dua faktor yaitu dua varietas selada (V) dengan menggunakan pupuk organik rumput laut (R). Pupuk organik rumput laut (R) terdiri dari lima taraf, yaitu R0 tanpa pupuk, R1 500 kg/ha (0,5 rekomendasi), R2 1000 kg/ha (1 rekomendasi), R3 1500 kg/ha (1,5 rekomendasi), R4 2000 kg/ha (2 rekomendasi). Varietas selada terdiri dari dua varietas, yaitu yang pertama selada kriting V1 (Lactuca sativa var. New grand rapid.), kedua selada merah V2 (Lactuca sativa var. new red fire). Kata kunci : Varietas selada, pupuk organik rumput laut, pertumbuhan dan Produksi. AbstractLettuce (Lactuca sativa L.) is a widely known leave vegetable. This vegetable is so rich in nutrient contents particularly vitamins and minerals that people can consume it to meet their nutrient requirements. This study was aimed at assessing the effects of sea grass organic fertilizer administration on the growth and production of lettuce. The study was conducted at the trial farm of Department of Agrotechnology, Faculty of Agriculture, Djuanda University, Bogor from March to April 2014. A completely randomized design with two factors consisting of lettuce variety (V) and sea grass organic fertilizer (R) was used. The varieties of lettuce consisted of curly lettuce (Lactuca sativa var. New grand rapid) (V1) and red lettuce (Lactuca sativa var. new red fire) (V2). Sea grass organic fertilizer (R) was given in three levels, namely no fertilizer (R0), 500 kg/ha (0.5 recommended rate) (R1), 1000 kg/ha (1.0 recommended rate) (R2), 1500 kg/ha (1.5 recommended rate) (R3), and 2000 kg/ha (2.0 recommended rate) (R4).

The purpose of the study is to determine the effect of concentration and frequency of application of banana weevil solution kepok against red chili plants is roofed with translucent ultraviolet plastic 70% which acts as a natural growth regulator.  Research on the provision of banana weevil solution covered in 70% translucent ultraviolet plastic in open land has not been found before.    The growing regulators from the gibberellin and cytokinin groups were able to boost the growth and yield of chili peppers. The method of using a random design of factorial groups, as the first factor is age consists of 9 levels, namely T1: age (14) HSPT, T2: age (14.21) HSPT, T3: age (14,21,28) HSPT, T4: age (14,21,28, 35) HSPT, T5 : age (14,21,28,35, 42) HSPT, T6: age (14,21,28,35,42,49) HSPT, T7: age (14,21,28,35,42,49,56) HSPT, T8: age (14,21,28,35,42,49,56,63) HSPT, and control (T0). The second factor is concentration consists of 3 levels, namely K1 (30%), K2 (45%), and K0 (0%). The results of the study obtained concentration of K1 (30%) with the amount of T6 administration is the best result in vegetative growth of the plant height change, the number of branches, and the width of the header, while the concentration of K1 (30%) give the best results on the length of the fruit, the dry weight of the fruit, and the diameter of the fruit from other treatments. Conclusion of the application of concentration and frequency of the sea of banana weevil kepok containing regulatory substances growing on red chili plants in the field covered with ultraviolet plastic roof significantly increases the growth and yield of red chili peppers.

The growth regulators of gibberellin and cytokinins are found in banana hump extract, while natural pesticides are found in the neem leaf extract. These two active ingredients can condition the growth and yield of chilies. There have not been any publications on the use of banana hump extracts and neem leaves to increase the growth and production of chili plants. The writing of this research article aims to explore the diversity of Indonesia's biological resources, among others, sword stalk banana hump extract and neem leaves which can stimulate the growth and yield of red chilies. Data analysis used a randomized block design with two variables and 3 repetitions. The first treatment used banana hump extract which consisted of four percentage levels, namely zero, fifteen, thirty, and forty-five percent, and the second treatment used neem leaf extract which consisted of four percentage levels, namely zero, fifteen, thirty, and forty-five, percent. A total of 600 grams of banana hump granules and neem leaves plus 1 liter of methanol, concentrated to a volume of 250 ml were used in this study. The results of the research showed that giving banana hump extract and neem leaves was able to stimulate the growth of leaf area so that it had an impact on increasing photosynthesis and plant metabolism. Fruit weight cannot be stimulated because, during the study, there was a long dry season, so there was a water deficit which was a limiting factor in the production of fruit formation.
