Peran Pertanian Organik Berbasis Ternak dalam Mendukung Ketersediaan Pangan Sehat dan Aman dn Mencapai Kelestarian Pertanian-Lingkungan
No full textPracticing intensive agriculture by implementing chemical substances in agriculture systems have been suspected cause problem on environment. Increase content of nitrate in drinking water and aquatic systems and greenhouse gases status of atmosphere may be due to the miss-practice of agricultural activity. Organic farming (OF) is one of techniques that may be implemented in order to solve this problem. Besides, its benefit in maintaining agro-environmental sustainability, practicing OF has weakness in the field. Therefore, to achieve its goal suitable strategy is needed. In the OF based on livestock, integration of crop-livestock-soil may occur, where among those three interact one each other and therefore ideal system (Zero wastes) may be established. Improvement of pasture increase, highly forage crop productivity and availability is expected influence on the performance of livestock. On the other hand, the return of animal wastes into pasture may tend to decrase the risk of environmental pollution
Ketersediaan Kalium dan Hasil Kedelai (Glycine max L. Merril) pada Tanah Vertisol yang Diberi Mulsa dan Pupuk Kandang
No full textThe aim of the research was to study the effect of kind of mulches, farmyard manure dosages (FYM), and their interaction on available potassium and yield of soybean on Vertisol. The experiment was conducted at green house on July to December 2002. Soil analysis was done at Soil Science Laboratory, Agriculture Faculty, Sebelas Maret University, Surakarta. It was arranged in Completely Randomized Design (CDR) with two factor and each treatment combination replicated three times. The first factor was kinds of mulch i.e. without mulch, rice straw at 5 ton/ha, and rice hull at 5 ton/ha. The second one was farmyard manure (FYM) dosage, i.e. 0,6 and 12 ton FYM/ha. Data analyzed for F Test and DMRT at 5% significancy and Stepwise Regresion to predict the optimum of soybean yield. The result showed that both kind of mulch and FYM influence available potassium at maximum vegetative phase of soybean, while their interaction significant on available K at harvested time, seed weight/plant and weight of 100 seeds. Available K increase coinside with FYM dosage. Stepwise Regression Analysis showed that treatment combination for the optimum of available-K at maximum vegetative phase, available-K at harvest time, seed weight/plant, and weight of 100 seeds were rice straw mulch and 2,76 ton FYM/ha, rice straw mulch and 0,035 ton FYM/ha, rice full mulch and 2,57 ton FYM/ha, and rice straw mulch and 1,1017 ton FYM/ha respectivel
Pengaruh Tingkat Adopsi Budidaya Padi Organik terhadap Keberlanjutan Budidaya Padi Organik di Kabupaten Boyolali
Get PDFBoyolali Regency of Central Java, Indonesia is an area that has developed organic rice cultivation. The development of the adoption rate organic rice cultivation has been conducted since 2009 and still sustainability until today. In fact, not all regions can accept and apply organic rice cultivation. This research was conducted from December 2016 to February 2017 in Boyolali Regency. This research aimed to analyze : (1) the adoption of organic rice cultivation in Boyolali Regency (2) the sustainability of organic rice cultivation in Boyolali Regency (3) the factors affecting the sustainability of organic rice cultivation in Boyolali Regency. This study was quantitative research with explanatory type. The analysis technique employed in this study was a Linear Regression; the sample consisted of 86 farmers living in the Sub Districts having widest organic rice farmland: Sambi, Mojosongo, and Andong. The result of research done by linear regression analysis using SPSS 23,0 program showed that the adoption rate of organic rice cultivation affected directly the sustainability of organic rice significantly with t-test probability (Sign) value of 0,017 less than specified α of 0,05. It indicated that seed preparation, land preparation, seeding, planting, fertilizing and maintenance affected the sustainability of organic rice cultivation in terms of economic and social
Potensi Penetralisir Radikal Bebas Rimpang Temu Lawak (Curcuma xanthoriza Roxb.) dan Temu Ireng (Curcuma Aerugonosa Roxb.)
No full textSolvent with different polarity used used in extraction of antioxidant compound from temu Lawak (Curcuma xanthoriza Roxb.) and Temu Ireng (Curcuma Aerugonosa Roxb.) spices. The solvent are Enthanol and acetone. Antioxidant extracts were analyzed in “neutralizer free radical” activity with DPPH Radical Scavenging Method. The activity compared with synthetic antioxidant BHA.Result of the research perform that Temu Lawak and Temu Ireng spices were potential as neutralizer free radical. Antioxidant extract of Temu Lawak spices have higher activity than Temu Ireng spices extract. The “neutralizer free radical” activity of 1% Temu Lawak extract is 1,9 times 300 ppm BHA activity, and 1% Temu Ireng extract is 1,24 times 300 ppm BHA activity. Solvent influential at “neutralizer free radical” activity of Temu Ireng spices extract, but it doesn’t influential at Temu lawak spices extract
Analisis Keterkaitan Produksi Kunyit di Indonesia dan Faktor-Faktor yang Mempengaruhinya
Get PDFThis study aims to analyze the relationship between turmeric production and the factors that influence it. The variables used in this study include production, export, import, inflation, land area, and exchange rate. This research is a descriptive research. The data in this study are data obtained from the Central Bureau of Statistics, Ministry of Agriculture, Ministry of Trade and Bank Indonesia. Research data were analyzed using regression analysis. The data used are secondary data for a period of 15 years namely 2002-2016. The results showed that the variables of export, import, inflation, land area and exchange rate together significantly influence the production of turmeric. Partially, the export, inflation and land area variables significantly influence the production of turmeric. While the import and exchange rate variables have no significant effect on turmeric production
Kajian Tingkat Penerimaan Panelis pada Dark Chocolate Bar dengan Penambahan Bubuk Kayu Manis (Cinnamomum burmannii)
Get PDFIndonesia is an agricultural country that is recognized as the third-biggest of cocoa producer in the world, after Cote d’Ivoire and Ghana. Widely cultivated in Indonesia, cinnamon is potential to be developed, since it has an excessive potency as an antioxidant and flavoring agents. The panelists’ acceptance of dark chocolate bars with cinnamon powder addition based on sensory tests was evaluated in this study. A completely randomized design (CRD) with one factorial was used. Variation of addition in cinnamon powder used in this study was 10% (F1), 15% (F2) and 20% (F3). Based on the result of scoring tests on colour, aroma, taste, appearance, and overall attributes of the sensory analysis, dark chocolate bar with 10% addition of cinnamon powder was chosen as the best formula. Thus, it may conclude that the highest level of panelists’ acceptance and preferences for some of the sensory attributes evaluated in this study is the dark chocolate bar with 10% addition of cinnamon powder. However, physical and chemical characterizations of the dark chocolate bars with cinnamon powder are still needed for further evaluation to gain a more comprehensive understanding about their quality attributes
Kualitas Serbuk Gergaji yang Difermentasi menggunakan Jamur Trichoderma viride
No full textAmount of 18 bag sacks of sawdust have been used to know the influence of sawdust fermentation with Trichoderma viride on nutrition quality. Randomized complete block design of factorial 2x3 used as the experiment design in this research. First factor consist of 2 old level of ferment (10 and 20 day) and second factor consisting of 3 inoculums dose level (2, 3 and 4%). Variable observed are dry matter degradation, change of protein and fiber contains.The result showed that dry matter degradation increased when inoculums dose and ferment time increased too. The most loss of dry matter got at 4% of inoculums dose (5,65%) and at 20 days ferment time (4,77%). The effect of inoculums dose is significant increasing protein containt. Highest increase got at 4% inoculums dose (169,12%) and the lowest at 2% (49,56%).There are interaction influence from both factor to the degradation of fibre contains on sawdust fermentation. At all of used inoculums dose fibre contains downhill in line with the increasing of ferment time and inoculums dose. The lowest degradation obtained at 2% treatment combination.Conclusion from this research is that more and more inoculums dose and time ferment hence more and more dry matter degradation, increasing protein and downhill fibre contains
