Abstract

Rice is the staple food of the majority of Indonesian people, including people in the Yogyakarta area, but until now the government still relies on massive, amounts of rice imports from abroad, so that it makes researchers interested in conducting research on Indonesian agricultural productivity which was sampled from the Yogyakarta area as a test material through Central Bureau of Statistics. This study aims to examine whether the harvested area, production level and productivity have a mutually influencing relationship. Researchers used Vector Auto Regression analysis. The results of the study found that the harvested area had an effect on the increase in production value, on the contrary it decreased in productivity, another effect was also found that production on land area and little effect on productivity.TRANSLATE with x EnglishArabicHebrewPolishBulgarianHindiPortugueseCatalanHmong DawRomanianChinese SimplifiedHungarianRussianChinese TraditionalIndonesianSlovakCzechItalianSlovenianDanishJapaneseSpanishDutchKlingonSwedishEnglishKoreanThaiEstonianLatvianTurkishFinnishLithuanianUkrainianFrenchMalayUrduGermanMalteseVietnameseGreekNorwegianWelshHaitian CreolePersian //  TRANSLATE with COPY THE URL BELOW Back EMBED THE SNIPPET BELOW IN YOUR SITE Enable collaborative features and customize widget: Bing Webmaster PortalBack//

Abstract

High demand for curly red chilies will cause prices to rise while production cannot fulfill consumer desires. This situation was caused by an imbalance of supply-demand, where the supply-demand imbalance can be caused by several changes such as changes in production technology, population growth or number of consumers, changes in income levels per capita and season (., Asriani, and Rasyid 2012). Research data as research subjects were 1) Price time series data, curly red chili production at production centers 2) Supply data of curly red chilies from Cikajang Garut Regency, Caringin Central Market, Gedebage Main Market and Kramat Jati Central Market, 3) Time series data price, production, supply, government policies and supporting data from the West Java Food Crops Agriculture Office, and related agencies. The data used were time series data and supporting data from: Price information centers in production centers, main markets and price information at the West Java Food Crops Agricultural Service, for each marketing agency data was carried out by tracing the marketing chain. The research analysis was carried out in several ways, namely theoretically and empirically at the production center and the wholesale market described descriptively. Theoretical price formation can be explained that prices was formed based on supply and demand. Prices derived from price formation can come from the District or Provincial Agriculture Office and be informed from the Commodity Price Information Center in production centers and forwarded to farmers, dealers, traders and wholesale markets. Price information can be conveyed to between market players, so that farmers and market players know your margin and profit. Empirically, it can be seen that price formation in production centers was not seen to be formed from supply and demand. The price in the wholesale market is the price determined by market players in the wholesale market based on the amount of supply entering the main market and price information between the parent markets. The information center at PIKJ does not have production data from production centers so that when the price hike occurs, the version of the Ministry of Agriculture is imports of chilies ("specifically for curly red chilies, there are no imports"). Imports indicate that the production / supply decreases without knowing the actual amount of production, in this case the price information speed was faster than the production data that was informed per year so that prices in farmers still do not increase, meaning that farmers do not enjoy price increases, in this case it can be said that market mechanism was not working well.

Abstract

Riparian ecosystems have a protective function of watersheds from pollution. One important component in riparian ecosystem is the presence of phytoremediation plants, which can degrade contamination content. This research is intended to identify the presence of undergrowth that functions as phytoremediation in Bojongsoang District which is one of the areas around the heavily polluted Citarum watershed zone[1]. The method used in this research is vegetation analysis using the quadrant method with 1x1 m2 plot size. Determination of sampling points used purposive sampling method. The results of the study found that the undergrowth as a potential phytoremediation included rumput teki (Cyperus rotundus), Beluntas (Pluchea indica), Alang-alang (Imperata cylindrica), Jejarongan (Chloris barbata), rumput gajah (Cyperus rotundus), and bayam duri (Amaranthus spinosus). Rumput teki (Cyperus rotundus) is phyto-extractions in mercury-contaminated soils and accumulators of Sn, Zn, As, Cu, and Pb. Alang-alang (Imperata cylindrical) is a cyanide phytoremediator which is able to extract Zn from contaminated soil, and absorb Pb from contaminated soil. Beluntas is able to accumulate Cu, Fe, Al, Pb and Zn in their roots, leaves and stems, and the leaves that can absorb Cr. Rumput gajah (Cyperus rotundus) are a Cd accumulator. Bayam duri (Amaranthus spinosus) hyperaccumulator against mercury. Studies on the presence of phytoremediation plants can provide preliminary information on the condition of riparian ecosystems in the Citarum watershed.

Abstract

The wick system is a hydroponic by utilizing the principle of capillarity of nutrient solutions that are absorbed by plant roots through the wick. Flannelette is a material that has the best water absorption and can be used as a wick, another alternative is stove wick. The concentration of nutrients given to plants must also be in needs. Samhong mustard is a type of mustard in the same class as pakcoy. This study aims to determine the effect of the type of wick and nutrient concentration on plant height, number of leaves, and plant weight using hydroponic wick system. The research method was carried out using two independent variables, namely the type of wick consisting of flannelette (S1) and stove wick (S2), and the nutrients concentration consisting of N1 (1,000 ppm), N2 (1,200 ppm), and N3 (1,400 ppm). The measurements results were compared using the Anova two-factorial design test with a level of 5%, and if the results were significantly different, then continued with the BNJ test at a significant level of 5%. The results showed that there was an effect of using different types of wicks and nutrient concentrations on the measurement results of samhong mustard. Flannel wick (S1) has better effect than the stove wick (S2), and the concentration of N1 nutrients has better effect than the concentrations of N2 and N3, with average plant height is 27.9 cm, average number of leaves are 18.8 strands, and the average plant weight is 128.6 g.

Abstract

Peanut production has decreased, among others, due to cultivation techniques, varieties, diseases and increasingly narrow planting areas. One of the cultivation techniques to increase crop yields is the use of liquid organic fertilizer (POC) and spacing. The research method used was Randomized Block Design, factorial pattern. Consisting of two treatment factors, namely POC concentration (0, 5, 10, and 15 ml L-1 water) and spacing (30 cm x 10 cm, 30 cm x 15 cm and 30 cm x 20 cm), repeated three times. .. The results showed that: (1) there was an interaction between POC treatment and plant spacing on the number of pithy seeds and dry seed weight per plot. Independently, liquid organic fertilizer and plant spacing had an effect on plant height, number of leaves, dry weight of stover, number of filled pods, number of empty pods, percentage of filled pods and weight of 100 seeds, and (2) At a spacing of 30 cm x 15 cm, The optimum POC concentration was 13.24 ml L-1 of water, with a maximum dry seed weight of 1.436 kg plot-1 or equivalent to 2.66 tons ha-1.

Abstract

The growth of wheat plants can be determined by measuring leaf area index and net assimilation rate. Both measurements require leaf area data. Measurement of leaf area of wheat in Indonesia requires a method that is not only accurate, but also easier and cheaper. One of them is the regression method. The purpose of this study was to determine an accurate regression equation model in predicting wheat leaf area. This research was conducted from March to June 2021 at the Experimental Station and Plant Production Technology Laboratory, Faculty of Agriculture, UNPAD, Jatinangor, Sumedang. The materials used in this study were various leaf area printing papers from wheat plants aged 14 days after planting (DAP), 28 DAP, and 42 DAP. The regression equation was assembled from the relationship between leaf area with leaf width and length, then compared with the actual leaf area that measured by scanning. The results showed that the linear, quadratic, cubic, and logarithmic regression equations had a coefficient of determination of more than 90% to predict leaf area, at the age of 14, 28, and 42 DAP, as well as all plant ages. Quadratic regression had a limit of data that can be entered, so it needed circumspection in using the formula. Cubic regression tended to have better accuracy in predicting leaf area at 14, 28, and 42 DAP, but the accuracy was the same as other regression equations at all plant ages.

Abstract

The demand for lettuce in Indonesia still cannot be fulfilled because lettuce production in Indonesia is still very low according to data from the Indonesian Central Statistics Agency in 2019. To meet the needs of lettuce at the request of the community and the market, an intensive cultivation technique is needed, namely the aeroponic system. The purpose of this study was to get the right timing of nutrition to produce the highest production of green lettuce plants in an aeroponic system. The research method used is an experimental method with the environmental design used is a Single Factor Randomized Block Design (RBD), which consists of 6 treatments repeated 4 times. The treatments consisted of t1 (5 minutes off, 30 seconds on), t2 (10 minutes off, 30 seconds on), t3 (15 minutes off, 30 seconds on), t4 (20 minutes off, 30 seconds on), t5 (25 minutes off, 30 seconds on), t6 (non-stop). Analysis of the data used is the F test at 5% level and to find out which treatment is the best, DMRT further test is carried out at the 5% level. The results showed that the t6 treatment gave better growth and yields than other treatments. At the age of 42 days after observation, the average plant height was 29.4 cm; the average number of leaves 15.22; the average diameter of the rods is 14.11 mm; mean root length 10.34 cm; 2003 mean leaf area, 59 cm2 ; and the average fresh weight was 670.1 g.
