Efforts to increase soybean production can be done by using new varieties and meeting the needs of the nutrient is also one attempt to do. One of fulfillment nutrients by fertilization. The purpose of this study is to examine the effect of banana hump MOL and cow dung manure on the growth and yield of soybean. Research was did in the experimental garden of Polytechnic Banjarnegara. The method was completely randomized design factorial pattern (Split plot). The first factor consisted of three levels of treatment that M0 = without MOL banana hump, M1 = concentration of 2,5 l/ha, M2 = concentration of 5 l/ha. The second factor consists of three levels of treatment that is P0 = without cow manure, P1 = dose of 5 tonnes /ha, P2 = dose of 10 tonnes /ha. Each treatment was repeated three times in order to get 27 experimental plots. Giving MOL banana hump and cow dung manure has not been able to increase the yield and growth of soybean plants. The yield on the dry weight of the plant, number of pods per plant and number of seeds is highest at a concentration of banana hump MOL 5 L ha-1. Cow dung manure dose of 10 tons ha-1 showed the highest yield on plant dry weight, seed number and weight of 100 seeds.

The aims of this study is to know the fruitfly and parasitoid populations in chili cropping in Banjarnegara. The study was conducted on April to October 2014. The fruitflies sampling was conducted by using fruitflies host maintenance. It means that collect the chilies wich has indicated attaced by fruitflies. One experimental unit was 10 pieces of chilies placed in a plastic jar filled with steril sand and covered with guaze. Further more, chilies left until the imago appearance, so that the fruitflies and parasitoid could be identified and could be accounted. The research was held in laboratory using a completely randomized block design with three experimens and nine repetitions, so there were 27 experimental units. Experimen consist of three sampling location wich attacked by chili fruitflies (Purwanegara, Karangkobar and Pagentan). The decision of certain location research used purposive sampling technique. Data analysis used F test, if there was significant different followed by Duncan’s Multiple Range Test at 5% level. The highest population of Bactrocera spp. in Pagentan is 20.78 individuals, while in district Purwanegara and Karangkobar are 2.11 and 1.67 individuals. Family Braconidae parasitoid population have not been able to reduce fruitfly population. Parasitoid population in distric Purwanegara, Karangkobar and Pagentan are 0.44, 0.22, and 1.22 individuals.

Study the importance of the effect of the addition of dolomite and potash fertilizer in an advanced stage based on the research that has been done and their interactions to increase the production of sweet potato. Research should be conducted during the months of September to December 2014 at the Polytechnic Experiment Land Banjarnegara. Materials used include : sweet potato seedlings, dolomite, KCl. Tools used include : a hoe, scales. The observed variables include : K is available, exchangeable Aluminium, tubers volume (cm3), weight of tuber per plant (kg), weight of tuber per hectare (kg), sugar content in the tubers. The experimental design used was a draft Plots Divided (split plot design) where there are two factors and each factor there are 2 treatment, namely : factor dolomite (D) include treatment : without the addition of dolomite (D0) and the addition of dolomite 5 ton/ha (D1). Factor the addition of potassium (K) include treatment : without the addition of potassium (K1), the addition of potassium up to 225 kg/ha (K2), the addition of potassium up to 300 kg/ha (K2), the addition of potassium up to 375 kg/ha (K3). Analysis of data using ANOVA test with a confidence level of 95%, followed by a further test DMRT. The results showed award specifies the treatment of dolomite no significant increase the weight of tubers per plant, weight of tuber per hectare and the volume of tubers per plant. Giving potassium treatment gives a noticeable difference to the volume parameter of tubers per plant. Interaction dolomite and potassium provide real difference in carbohydrate content in the delivery of 5 tons per hectare dolomite and potassium of 300 kg/hectare.

Longsor lahan merupakan bencana alam geologi yang diakibatkan oleh gejala alami geologi maupun tindakan manusia dalam mengelola lahan atau ruang hidupnya. Analisis kerawanan bencana dapat dilakukan dengan berbagai metode salah satunya adalah metode pemetaan berbasis Sistem Informasi Geografis (SIG). Metode yang digunakan pada penelitian ini adalah dengan menggunakan analisis spasial. Data yang telah diperoleh berupa Peta Sebaran Curah Hujan, Peta Kemiringan, Peta Tata Guna Lahan dan Peta Jenis Tanah diberi skor sesuai dengan parameter dan kriterianya kemudian dilakukan tumpang susun (overlay). Penentuan daerah rawan longsor menggunakan SIG dengan metode Indeks Storie yaitu perkalian setiap parameter-parameter. Hasil analisis itu nantinya akan menghasilkan nilai kisaran indeks storie. Selanjutnya nilai kisaran ini dikonversi pada beberapa tingkatan rawan longsor. Wilayah Kecamatan Pegentan dipengaruhi oleh 4 Stasiun Hujan terdekat, yaitu Stasiun Hujan Karangkobar, Stasiun Hujan Limbangan, Stasiun Hujan Pejawaran dan Stasiun Hujan Pagentan. Dari ke 4 Stasiun Curah Hujan tersebut diketahui bahwa wilayah yang mempunyai nilai curah hujan paling besar adalah wilayah yang dipengaruhi oleh Stasiun Hujan Pagentan yaitu sebesar 3.703 mm/tahun. Sedangkan curah hujan terkecil adalah wilayah stasiun Curah Hujan Karangkobar sebesar 1.583 mm/tahun. Kemiringan di Kecamatan Pagentan didominasi oleh kemiringan berbukit, curam, sangat curam dan terjal. Sehingga wilayah Kecamatan Pagentan berdasarkan kemiringannya sebagian besar merupakan wilayah yang rawan terhadap terjadinya longsor. Berdasarkan hasil analisa maka didapatkan Peta Kawasan Longsor Kecamatan Pagentan. Kecamatan Pagentan terdapat wilayah yang mempunyai kerawanan sangat rawan, sehingga perlu mendapatkan perhatian khusus berkaitan dengan mitigasi bencana.

Azolla is an organic material wealthy in nutrients, particularly nitrogen, required for lowland rice. The employment of Azolla as fertiliser for rice doesn’t ought to be costly and might even suppress weed growth. This study aimed to see the most effective application of Azolla to rice growth. The analysis technique used was a Randomized Block Style Design (RAKL) with a pair of treatments being tried. The treatment of 1 dose of Azolla consisted of a dose of Azolla 0 (A1), Azolla 30 g/bucket (A2) and a dose of Azolla 45 g/bucket. (A3). Treatment 2 was immersion consisting of immersion (B1) and no immersion (B2). Azolla was applied 2 times, half the dose 1 week before planting and 10 days after planting. Every treatment was recurrent 5 times thus there were 30 experimental treatments. The data were analyzed using the F test, if it was significantly different, it was followed by Duncan's test (DMRT) at a 5% level. The result of this research is that Azolla dose treatment and immersion have not been able to increase plant height and the number of tillers

Eggplant pest attack, does not only decrease quantity of the yields, but also the quality. Because of this, it needs effort to use resistant eggplant againt the pests. The purpose of this research was to evaluate the intensity of pest attack on several types of eggplant and their effect on the yield. The design used in the study was a completely randomized block design (RCBD). The research was consisted of 4 treatments with 3 replications. The treatments were 4 types of eggplant that were purple , white eggplant, green eggplant, and green streak white. Data were analyzedby F Test, if it was significantly different, by then it was continued with DMRT (Duncan’s Multiple Range Test) at the level of 5%. Pest attack intensity of grasshopper (Orthroptera: Acrididae), caterpillars (Lepidoptera: Pyralidae), ladybird Epilachna sp. (Coleoptera: Coccinellidae), leafhopper Amrasca sp. (Hemiptera: Cicadellidae), and Aphis sp. (Hemiptera: Aphididae) on the eggplant types showed there was no significantly difference. The intensity of pest attacks which were not significantly different in all types of eggplant along with the results of analysis of plant height and number of fruits which also showed there was no significantly difference in all type eggplants.
