Abstract

Organic matter is important to soil aggregate stability. The research of effect dosage of goat manure tos oil aggregate in organic farming system was do neon Andisols soil in Permata Hati Farm, CiburialHamlet, North Tugu village, Cisarua sub-district, Bogor district, West Java province. The research was conducted on October 2012 until the end of February 2013. The research purposes are: a) Know the goat manure’s dosage influence on soil aggregate in organik farming system, b) Determine the dos age of goat manure that can provide the best Mean Weight Diameter (MWD) and Aggregate Stability Index (ASI)in organik farming system. The research used randomized completely block design (RCBD) with 6 treatments and 3 replications. Goat manure dosage were used as treatments are 0 ton ha-1, 5 ton ha-1, 10 ton ha-1, 15 ton ha-1, 20 ton ha-1, and 25 ton ha-1. Data was analyzed by ANOVA and Duncan’sMultiple Range Test (DMRT) at 5% level. The research results are showed, with initial number of C-organic >4.5%, goat manure application was significant to change soil aggregate. Goat Manure 5 ton ha-1was enough to increasing Mean Weight Diameter (MWD) and ASI (Aggregate Stability Index).

Abstract

Intercropping cultivation model is commonly used in organic farming system. The system is aimed to save land and fertilizer aside from creating biodiversity in a portion of a planting. The research was conducted in Permata Hati Farm, Ciburial Village, Cisarua Sub district, Bogor Regency, West Java from October 2012 to January 2013. The purposes of the research are: a) to know the effect of goat dung application toward the growth and yield of organically managed carrot and scallion intercropping, and b) to determine the best quantity of goat dung to promote growth and yield of carrot and scallion intercropping. Randomized Completely Block Design (RCBD) with 6 treatments and 3 replications was used in this experiment. The treatments applied were 0 ton ha- 1, 5 ton ha-1, 10 ton ha-1, 15 ton ha-1, 20 ton ha-1, and 25 ton ha-1 of goat dung. Duncan’s Multiple Range Test (DMRT) at the confidence level of 95% was used to analyze the result. The application of 15 ton ha-1 goat dung affected scallion’s height and number of seedlings as well as carrot’s biomass and height. This dosage resulted in the best yield of scallion and carrot intercropping.

Abstract

Tape yeast in certain dose is required in making tape. Addition of 5% sugar could increase the sweetness as well as energy for the microorganissm. The experiment about the effect of yeast dosage and sugar addition on the quality of wheat grain tape in the Laboratory of Faculty of Science and Mathematics Satya Wacana Christian University started from 29th February until 23rd April 2012. This research used Randomized Block Design (RBD) with six treatments as follows: 1% yeast; 2% yeast; 3% yeast; 1% yeast with sugar; 2% yeast with sugar; 3% yeast with sugar. Finally, data of the result were analyzed using analysis of variance (ANOVA) and honestly significant difference (HSD) at 5% level. The research showed that: 1) 1% yeast dose had the highest quality of wheat tape compared to 2% and 3% yeast dose, 2) 1% yeast dose with sugar gave the best taste from organoleptic test.

Abstract

ABSTRACTRainfed ricefield, planted at least for one cropping season in a year, depends heavily on rainfall for its water supply. This land generally is low in fertility as indicated by the limited availability of essential plant nutrients in particular nitrogen (N), phosphorus (P), and potassium (K) as well as organic matter. Its productivity is relatively low with a rather erratic precipitation distribution. In order to overcome fertility issue in rainfed land, it is necessary to conduct an integrated nutrient management; one of which is by implementing location specific nutrient management. This study aims to seek the appropriate nutrient management in rainfed paddy field of Semawung village in the sub-district of Andong of Boyolali regency to be provisioned as a technological tool of location specific nutrient management. Research on nutrient management of gogo rancah system-based paddy production was carried out from October 2014 to January 2015. The field experiment was arranged in a Randomized Block Design involving eight treatments and three replications for each treatment. Treatments were combinations of NPK fertilizer, Organofosfat, and straw-based organic fertilizer. Nutrient management using NPK fertilizer and its combination with Organofosfat or organic fertilizer had very significant effect on plant height and number of stem per hill, significantly affected number of panicle per hill, panicle length, and number of fully-filled grain but did not result in difference of fully filled grain percentage and weight of 1000 grains. There was no significant difference between the treatment of 100% of NPK fertilizer and the combination of 75% of NPK fertilizer with straw-based fertilizer regarding these variables: number of stem per hill, number of panicle per hill, panicle length, number of grain per hill, number and percentage of fully-filled grain, weight of 1000 grains, and weight of fresh grain and milled grain yield. Therefore, the latter treatment is feasible as an option of location-specific nutrient management Semawung village.

Abstract

The availability of nutrients from the soil is very influential on the growth of a plant. Nitrogen and or potassium nutrients are the limiting factors in the productivity for flowering of viola (Viola tricolor L.) at andosol kopeng. The purpose of this study was to determine the effect of limiting nutrients at adosol kopeng on flower productivity of viola plants.Research was carried out in May to September 2022 in Experimental Garden Salaran, Faculty Of Agriculture and Business, Satya Wacana Christian University, Salatiga. This research was approach using Minus One Elements Technique with 8 treatments, that is NPK, PK, NK, NP, N, P, K and Without NPK repeated 4 times therefore 32 units of experiment were tested. The results were analyzed by (ANOVA). DMRT at 5% level of probability was used to know the difference between treatments plant high, number of leaves, plant weight, plant dry weight, number of flowers, flower diameter and length of flowering time. Without N and K nutrients, plants only produce treatments plant high, number of leaves, plant weight, plant dry weight, number of flowers, flower diameter and length of flowering time respectively 79.43%, 50.24%, 63.89%, 50%, 71.95%, and 100% compared to NPK treatments.

Abstract

Hara fosfat dan atau kalium menjadi faktor pembatas pada pembentukan bunga dan produksi benih tanaman viola (Viola cornuta L). Penelitian ini bertujuan untuk mengetahui pengaruh hara pembatas terhadap jumlah bunga dan komponen hasil benih tanaman tetua betina viola. Penelitian dilaksanakan pada Juni sampai Agustus 2018 di kebun PT. Selektani Horticulture, Magelang. Penelitian ini dilakukan dengan pendekatan Minus One Element Technique dengan 5 perlakuan yaitu Standar Sub Tropis, modifikasi tropis, P, K, PK yang diulang sebanyak 5 kali sehingga didapatkan 25 satuan percobaan. Hasil pengamatan dianalisis dengan metode sidik ragam dengan akurasi 95%. Untuk mengetahui perbedaan antar perlakuan digunakan Uji DMRT dengan tingkat probabiltas 5%. peubah pengamatan meliputi jumlah bunga, jumlah polong, bobot basah polong, bobot kering polong, bobot kering benih, jumlah biji per polong. Dari sisi mutu meliputi daya berkcambah benih (DB), kecepatan perkecambahan (KCT) dan keserempakan perkecambahan (KST). Tanpa pemupukan P dan K, tanaman hanya menghasilkan jumlah bunga, jumlah polong, benih bersih per tanaman dan daya berkecambah berturut-turut 76.62%, 73%, 57.95% dan 53% dibandingkan perlakuan Standar Sub Tropis. Kata kunci: minus one element technique, produksi benih, tanaman hias, unsur P dan K.
