Abstract

The purpose of this research were to determine the composition of sand fraction and chemical properties at revegetation area. The research was conducted from April to October 2019 . The mineralogical Compositions of sand fraction were analyzed using a Polarizing Microscope (PM) at the laboratory of Mineral BB Litbang SDLP, Bogor. The results showed that the composition of sand fractionof soil at revegetation area was dominatd by quartz,with small amounts of opaque, zircon,weathered mineral, rock fragment, and tourmaline.Chemical properties indicated that the soil at revegetation area showed pH from 6,05 to 6,49, had low content of cation exchange capacity in the whole layers, very high content of base saturation, very low to low organic carbon. Exchangeable K and Na are low in the whole layers, the moderate content of potential potassium. Both exchangeable Ca and Mg were lot to moderate. Potentioal P content in soil varies from moderate to high.Soil management in revegetation area should be focused on Maintaining soil fertility through application of liming, and fertilizers

Abstract

The Effect of Post-Mining Soil Planting Media and Book Lengths on the Growth of Pepper Cutters (Piper nigrum L.) Varieties of Malonan I, Under the guidance of Mahdalena and Iin Arsensi. The purpose of this study was to determine the response of the growth of pepper cuttings (Piper nigrum L.) Malonan I variety using post-mining soil planting media. This research was carried out in Sungai Mariam Village, Anggana Subdistrict for 6 weeks from September to November 2018. The research was arranged in a Randomized Block Design (RBD) with Factorial experiments consisting of 2 factors with 3 replications. The first factor is the length of the book consists of two levels, namely s1 (length 3 books) and s2 (length 5 books). The second factor of the growing media consists of 3 levels, namely t1 (mining land), t2 (mining land and manure), and t3 (mining land and compost). The results showed that the treatment of post-mining soil planting media and the length of cuttings did not have a significant effect on all parameters, when growing shoots, number of shoots, and shoot length were 2, 4, 6 weeks after planting.

Abstract

This study aims to determine the growth rate of patchouli (Pogostemon cablin, Benth) with f rotoone administration and coconut water. The research was conducted on land peraktek Polytechnic State Agricultural Samarinda time for 2 months starting from the month of June to August 2016. The research design used was completely randomized design (CRD) with 6 treatments and 6 replications. treatment is a0 = control, a1 = Immersion Coconut Water with a concentration of 50% pure coconut water, a2 = Immersion Coconut Water with a concentration of 100% pure coconut water, a3 = Immersion Rootone F with a concentration of 50 grams, a4 = basting mixture Coconut Water 50% with a mixture of 50 grams Rootone F, basting mixture a5 = 100% Coconut Water with a mixture Rootone F 50 grams. Results of analysis of variance showed that the Effects of Immersion Water Oil And Rootone F on Growth Cuttings Plant Patchouli (Pogostemon cablin, Benth) a very significant effect on the number of shoots 2 weeks after planting, plant height 2 WAP, 6 WAP, stem diameter 2 WAP, 4 WAP, 6 WAP and 8 WAP. real effect on the number of parameters shoots 4 WAP, 6 WAP, 8 WAP, plant height 4 and 8 WAP.

Abstract

The purpose of this study was to determine the effect and interaction of Giving Bokashi Organic Fertilizer and NPK Phonska Fertilizer on Growth and Production of Large White Ginger Plants. The study was conducted for 5 months, starting in January 2018 until June 2018 starting from the preparation of planting media, nurseries, planting, to data collection. The location of this study was carried out in the experimental garden Faculty of Agriculture, Widya Gama Mahakam University Samarinda at. K.H. Washid Hasyim. The study was arranged in a 4x3 factorial Randomized Block Design (RBD) and repeated 4 times. The first factor is the Bokashi organic fertilizer (B) consisting of 4 levels, namely: B0 (control), B1 (200 g / polybag), B2 (400 g / polybag), and B3 (600 g / polybag). The second factor is NPK Phonska (P) fertilizer consisting of 3 levels, namely: P0 (control), P1 (30 g / polybag), and P2 (40 g / polybag). The results showed that the treatment of Bokashi organic fertilizer and NPK Phonska fertilizer had a very significant effect on all parameters of observation, while the interaction of the two did not significantly affect all parameters of observation. In general, a dose of 400 g of Bokashi organic fertilizer for growth and production of large white ginger plants produces the best treatment, and a dose of 30 g of NPK Phonska fertilizer for growth and production of large white ginger plants produces the best treatment.

Abstract

Test of Corn Leaves (Zea mays) Compost and NPK Phonska Fertilizer on Plant Height and Peanut Yield (Arachis hypogaea L.). This study aims to determine the effect of giving corn leaf compost fertilizer and NPK phonska fertilizer and its interactions on the growth and yield of peanuts. The study used a Randomized Block Design with a 4x4 experiment with 2 factorial replications 3 times. The first factor is the dose of compost of corn leaf compost consisting of 4 levels, namely: o0 (control), o1 (100 g / plant), o2 (200 g / plant), o3 (300 g / plant). The second factor is the NPK fertilizer dosage consisting of 4 levels, namely: k0 (control), k1 (5 g / plant), k2 (10 g / plant), k3 (15 g / plant). The results showed that the treatment of corn leaf compost did not have a significant effect on plant height at 30.60, and 90 days after planting, pod weight and number of pods. Phonska NPK fertilizer does not have a significant effect on plant height at 30, 60, and 90 days after planting, but it has a significant effect on the number of pods and pod weight. The interaction between the compost dose of corn leaf compost and NPK phonska had no significant effect on plant height, pod weight and number of pods.

Abstract

The Malonan-1 variety is a pepper plant originating from East Kalimantan which has become a national superior pepper. This pepper contains around 2,35% essential oil, oleoserin 11,23% and piperine 3,82% and tolerance to stem rot disease. Preliminary survey results in the village of Batuah, Kutai Kartanegara District, East Kalimantan, it was found that the stem rot disease in Malonan-1 pepper, therefore it is necessary to conduct research to find out how much the intensity of the stem rot disease at this time and identify fungi that cause stem rot rot disease in pepper plants. This research was conducted for 5 months starting from January to May 2019. The research location was in Batuah Village, Loa Janan Subdistrict, Kutai Kartanegara District and in the Plant Disease Pest Laboratory, Faculty of Agriculture, Mulawarman University. Research includes activities in the field and in the laboratory. The activity in the field is a direct survey of eight pepper farmer groups and calculating the intensity of the disease. Also carried out samples of symptomatic stem rot disease to be brought to the laboratory. Activities in the laboratory are the preparation of tools and materials to isolate samples of pepper plants. The isolated fungal colonies were purified and then idenfied and continued with Koch's postulate. The average intensity of stem rot disease at the current Lada plant in Batuah village is 14,58% (mild), the highest intensity in the Young Lada farmer group is 26,52% and the lowest intensity in the Beringin Jaya Farmer group is 4.3%. Based on the results of isolation, the root disease of the pepper plant (Piper nigrum L) in Batuah Village, Loa Janan District, Kutai Kartanegara Regency is Phytophthora capsici L.
