Abstract

Budidaya kakao diindonesia umumnya petani masih menggunakan teknik tradisional,  Hal tersebut juga diiringi minimnya inovasi dan teknologi pada budidaya kakao sehingga banyak sekali pohon kakao kurang terawat dengan baik. Permasalahan budidaya kakao biasanya karena kurangnya pemanfaatan teknologi produksi kakao tidak optimal dan penggunaan bahan tanam yang tidak jelas asalnya, Petani juga kurang melakukan pemupukan yang sesuai aturan, dan kurang dalam perawatan, sehingga serangan organisme pengganggu tanaman meningkat Penggunaan pupuk kimia tidak sesuai dengan anjuran, mengakibatkan kualitas dan kesuburan tanah menurun. Solusi untuk mengurangi pemakaian pupuk anorganik adalah memanfaatkan bahan organik yang berasal dari tanah akar bambu dan mikroorganisme sebagai pupuk hayati. Bakteri akan meningkatkan mekanisme pertumbuhan biomassa akar. Isolat bakteri rizosfer diperoleh dari sekitar akar tanaman bambu. Tujuan dari penelitian ini adalah Untuk mengetahui respon pertumbuhan tanaman kakao (Theobroma cacao L.), pada perendaman dan pemeberian microkapsul bakteri rizosfer dengan taraf perlakuan yang bervariasi. Desain penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL), 16 perlakuan dan 2 ulangan. Faktor pertama adalah perendaman biji kakao menggunakan suspensi bakteri rhizosfer yang terdiri dari A0=0 jam; A1= 8 jam; A2=16jam dan A3= 32 jam dan faktor kedua adalah penambahan mikrokapsul yang terdiri dari C0= 0 gr; C1=10 gram; C2= 20 gr; C3= 30 gram.

Abstract

Cocoa (Theobroma cacao L) is an annual plant that can bear fruit at the age of 4 years and if managed properly, it’s production can last more than 25 years. Seeding is a technique for multiplying plants by vegetative and generative methods. The purpose of this research is to determine the effect of application of cow urine POC and cocopeat on the growth of cocoa plant seeds and the effect of their interaction. This study used a factorial randomized block design (RAK) consisting of 2 treatment factors, namely the application of cow urine POC (S) consisting of 4 levels, namely S0 (0 ml/polybag), S1 (150 ml/polybag), S2 300 ml/polybag. ) and S3 (450 ml/polybag) and the application of cocopeat (C) consisted of 4 levels, namely C0 (0 g/polybag), C1 (100 g/plobag), C2 (200 g/polybag) and C3 (300 g/polybag).. Parameters observed were plant height (cm), number of leaves (strands), stem diameter (mm), wet weight (g), dry weight (g). The results showed that the application of cow urine POC had no significant effect on stem diameter, but had a significant effect on plant height, number of leaves and plant dry weight, and had a very significant effect on wet weight of cocoa seedlings. The application of cocopeat had no significant effect on plant height and stem diameter, but it had a very significant effect on the parameters of the number of leaves, plant wet weight and plant dry weight. The interaction between the application of cow urine POC and cocopeat had no significant effect on plant height, number of leaves, stem diameter, wet weight and dry weight of plants.

Abstract

Cocoa (Theobroma cacao L.) is one of the main plantation commodities which plays an important role in the Indonesian economy, and 3rd ranked in the world for cocoa producers. One effort to increase cocoa productivity was the use of biological fertilizer. The aim of this research was to determine the effect of using rhizosphere bacterial microcapsules as biofertilizer on the vegetative growth of cocoa leaves. The research design used was a Completely Randomized Design, with two factors, the first was immersion the cocoa beans using a rhizosphere bacterial suspension consisting of A0=0 hours; A1= 8 hours; A2=16 hours and A3=32 hours and the second factor is the addition of microcapsules consisting of C0=0 gram( g ); C1=10gr, C2=20gr, C3=30gr. Combination The treatment was repeated twice so that 32 plants were obtained. For the parameter of observing the number of leaves, the best results were shown in the 8 hour immersion treatment with an average number of leaves of 12.63, followed by the treatment of giving 20 grams of capsules with an average number of leaves of 11.75. The lowest number of leaves was shown in the 16-hour and 32-hour immersion treatments at 10.75. Meanwhile, for the observation parameters of leaf area, the best results were shown in the 32 hour immersion treatment with an average leaf area of 73.49 cm 2 and the lowest results were shown in the non-immersion treatment with an average leaf area of 59.88 cm 2 . The results of the analysis of variance showed that all treatments had no significant effect

Abstract

Eggplant production in Indonesia is still low and only accounts for 1% of the world's needs, this is because the cultivation culture is still not intensive. Infertile soil is also a factor in low eggplant production. In order for growth to be good, it must look at the ideal growing conditions and nutrients in the soil. This study aims to determine the optimal concentration of liquid organic fertilizer in increasing the growth and production of purple eggplant plants. The research design applied is a non-factorial Randomized Group Design (RGD) consisting of 1 factor, namely Liquid Organic Fertilizer, with 4 experimental levels, namely P0 (0 ml /l water), P1 (50 ml /l water), P2 (100 ml /l water), P3 (150 ml /l water). The results showed that the concentration of liquid organic fertilizer had a very significant effect on all variables observed, except the number of fruits, fruit weight and production weight were not significantly different. LOF treatment with a concentration of 150 ml/l water gave the best results on the parameters of plant height, stem diameter, number of flowers, number of fruits, fruit length, fruit weight, production weight and production ha/ton

Abstract

Shallots (Allium ascalonicum. L) have long been cultivated by farmers in Indonesia as commercial farming. In increasing the production of shallots, maximum nutrients are needed, with the use of mixed compost and mixed POC root nodules. This research method used a factorial Randomized Block Design (RAK) consisting of 2 factors with 16 treatment combinations and 2 replications. The factors that must be studied are the main factors in the treatment of mixed compost (JC) consisting of 4 levels, JC0 = Control, JC1 = 1 Kg/plot, JC2 = 2 Kg/plot, and J3 = 3 Kg/plot. The second factor was mixed root nodule POC (BA) consisting of 4 levels, namely BA0 = Control, BA1 = 100 ml/liter water/plot, BA2 = 200 ml/liter water/plot, BA3 = 300 ml/liter water/plot. The parameters of this study were the number of leaves per sample aged 2,3,4 and 5 WAP (strands), wet tubers per sample (g), dry tubers per plot (g), production conversion per Ha (kg). The results showed that the mixed mixture treatment had a very significant effect on the parameters of the number of leaves per sample (strands), dry tubers per plot (g), and production conversion per hectare (kg), but had a significant effect on the parameters of wet tubers per hectare (g). The use of mixed root nodule POC had a very significant effect on the number of leaves per sample (strands), dry tubers per plot (g), and production conversion per Ha (kg), but had a significant effect on wet tuber parameters per sample (g). The interaction of mixed utilization and POC of mixed root nodules did not have a significant effect on all parameters.

Abstract

The purpose of this study was to determine how several varieties of soybean (Glycine max (L.) Merrill) responded to the provision of composted rice straw waste to enrich goat manure in terms of growth and production. This study used a factorial randomized group design, a method with two factors and three replications. In this study, the first factor was soybean variety (V) divided into four parts, such as V1=Grobogan Soybean Variety, V2=Anjasmoro Soybean Variety, V3=Devon Soybean Variety, and V4=Wilis Soybean Variety. The second factor is grouped from K0 = 0 kg/plot, K1 = 1 kg/plot, K2 = 2 kg/plot, and K3 = 3 kg/plot as four components of rice straw waste compost enriched with goat manure. Meanwhile, the parameters that became the object of research were plant height (cm), number of productive branches, stem diameter (mm), number of pods, number of filled pods, number of empty pods, and weight of 100 seeds. The results explained that the growth response of soybean varieties influenced plant height, number of pods, number of filled pods, number of empty pods, seed production, and 100-seed weight. In contrast, the number of productive branches and stem diameter had no effect. Giving rice straw compost enriched with goat manure affects the number of productive branches and the number of filled pods, while plant height, stem diameter, number of pods, number of empty pods, seed production, and 100 seed weight do not have an effect. The interaction between the application of several varieties of soybean plants and composted rice straw waste enriched with goat manure did not show a significant effect on all parameters of the growth and production of soybean plants.

Abstract

The excessive use of pesticides and synthetic fertilizers will result in a decrease in nutrients resulting in an impact on shallot productivity, so that shallot production in Indonesia still does not meet consumer demand. This study aims to determine the effect of dosing of vegetable pesticides and POC of goat urine on shallots. This study used a factorial Group Random Design (RAK), with 3 replicates. The first factor is the use of vegetable pesticides from mahogany seeds with 3 concentration levels, namely M0 = 0 ml/100 ml of water/plot, M1 = 30 ml/100 ml of water/plot, and M2 = 60 ml/100 ml of water/plot. The second factor is liquid organic fertilizer from goat urine with 3 concentration levels, namely K0 = 0 ml/liter of water/plot, K1 = 200 ml/liter of water/plot, and K2 = 400 ml/liter of water/plot. The variables observed were plant height, wet weight, dry weight, attack intensity, and arthropod diversity. The results of the study were taken at the age of 2,3,4,5, and 6 weeks after planting (MST). The treatment of vegetable pesticides and POC of goat urine did not produce an interaction on the observed variables of plant height, wet weight, and dry weight. The results showed that the treatment of vegetable pesticides with the highest concentration at M2 resulted in a plant height of 32.60 cm, a wet weight of 35.14 grams and a dry weight of 27.11 grams. Meanwhile, the treatment of goat urine liquid organic fertilizer was the highest, resulting in a plant height of 32.73 cm in the K2 treatment. For wet weight, and dry weight, the highest treatment was in K1 with a wet weight yield of 36.92 grams, and dry weight of 29.14 grams. Regarding the intensity of pest attacks, the results of the study showed that in the first week no attacks were found. However, in weeks 2 to 6 attacks began to appear, with the highest intensity of 0.19 in the M0 treatment. The analysis of Arthropod diversity showed an index of 1.8. which indicates the level of species diversity that is currently in the research field. Overall, this study shows an increase in the growth and production of shallot plants.
