Abstract

Water balance modeling is one approach that can be used to predict the dynamics of soil water content for plant growth, so it can calculate the amount of crop water requirements, particularly at critical periods during which the soil moisture content is very low and in normal circumstan ces. The experiment wasconducted April-November 2010 in Merauke district of Papua provi nce. The collect ion of clim ate data (rainfall, temperature, humidity), land information(based on soil type and land use map, primarily to det ermine water holding ca pacit y and root z one depthof the soils). Land water balance analysis was con ducted for each a nalysi s of distri cts using Thornthwaite and Mather (1957). Furthermore, the results of water balance of land was mapping used the geographic information system (GIS) method for knowing the districts that have the periods of water deficit or water surplus. The results showed that the dom inant patterns of rai nfall in t he district of Merauke is pattern A is a pattern that suggests that there is a clear di fferen ce between the a mount of rai nfall duri ng th e rain y sea son t o dry season. Merauke district experienced a period of water deficit of about 4-7 months for a year. Sub districts that have a period and a high amount of water deficit isKuprik for 7 consecutive months. Sub districts that have a short period of deficit 4 months is Jagebob, Kimaan and Muting. The potential for planting food crops in Merauke district ranges from 5-7 months. The surplus per iod i s about 3-6 mont hs of November to May/June. Sub districts that have a longer period surplus isJagebob and Kimaant is 6 months. The most of the sub districts (6 sub districts) in the Merauke districthas a surplus of water> 1000 mm / year. There are only two sub districts that have surplus water <1000 mm / year is Kupri k and Sota. Sub distri cts t hatobtain high water surplus for the year is Semangga. Pot ential of th e short growing season found in Kuprik (3 months) while the potential of the growingseason is long (6 months) in almost every sub district (Semangga, Okaba, Muting Kimaan, and Sota). Water bal ance model is developed en ough valid forpredicting soil water availability and timing of food crop planting in Merauke district of Papua province

Abstract

Early detection and identification of soybean diseases is important to support better productivity of soybean. The demand for the availability of an expert on soybean disease is very high, especially for the beginners in the field of agriculture. However, the number and time allocation of the experts are not adequate to serve farmers located in different geographical areas. Therefore, an expert system is proposed as a solution to use as a diagnostic tool for soybean diseases just like a human expert. It will be even easier when the system is implemented into an Android-based application to be used anywhere and anytime. The objective of this study was to analyze and design an expert system for early identification of soybean diseases. This study was adopting the Expert System Development Life Cycle (ESDLC) approach. The stages were project initialization, knowledge engineering process, and implementation. The study was started with the project initialization phase that conducted in September 2014 and the completion of the implementationphase in August 2015. The results of research were in the form of document analysis and prototype system.

Abstract

INDONESIA Provinsi Papua memiliki potensi lahan pertanian cukup luas yang tersebar di 20 kabupaten. Sentra pengembangan pertanian khususnya komoditi jagung banyak dibudidayakan di lahan dataran rendah beriklim kering di kabupaten Keerom, Jayapura dan Merauke. Komoditi jagung hibrida banyak diusahakan pada agroekosistem yang beragam sehingga diperlukan varietas yang dapat beradaptasi luas pada berbagai lingkungan. Penelitian bertujuan untuk menilai stabilitas hasil dan adaptabilitas 9 galur harapan jagung hibrida dan 3 varietas pembanding di 3 lokasi di Papua. Penelitian dilaksanakan mulai April - September 2010 di 3 sentra produksi jagung yaitu Kabupaten Jayapura (Nimbokrang), Kabupaten Keerom (Arso) dan Kota Jayapura (Koya Barat). Penelitian menggunakan Rancangan Acak Kelompok disetiap lokasi percobaan dengan 12 perlakuan, dan setiap perlakuan diulang 3 kali. Selanjutnya dianalisis menggunakanadditive main effects and multiplicative interaction (AMMI) untuk mengetahui stabilitas hasil dan adaptabilitas setiap galur. Bahan penelitian terdiri atas 9 galur harapan jagung hibrida yaitu G1001, G1002, G1003, G1004, G1005, G1006, G1007, G1008, G1009, dan 3 varietas pembanding yaitu Makmur 4, AS1, dan Bima 4. Setiap galur ditanam pada petak berukuran 3,75 m x 4 m, dengan jarak tanam 75 cm x 45 cm dan 1 tanaman perumpun. Stabilitas dan adaptabilitas galur-galur yang diuji dihitung dengan metode analisis AMMI. Hasil penelitian menunjukkan bahwa, kisaran hasil 9 galur yang diuji adalah 4.00 – 7.44 t/ha dengan rataan 5.86 t/ha. Hasil tertinggi dimiliki galur G1006 (7.44 t/ha). Hasil analisis gabungan memperlihatkan bahwa, lokasi, galur dan interaksinya sangat nyata untuk hasil biji. Penggunaan model AMMI menunjukan bahwa Galur G1002, G1003, G1008 dan Galur G1009 teridentifikasi sebagai galur stabil pada tiga lokasi uji (beradaptasi luas). Galur G1006 beradaptasi spesifik untuk lokasi Arso, G1005 spesifik untuk lokasi Nimbokrang dan galur G1007 untuk spesifik lokasi Koya Barat, dan Galur G1009 berpeluang diusulkan sebagai varietas unggul jagung hibrida berdaya hasil tinggi.INGGRIS

Abstract

The statistical method for measuring rice productivity by the CBS is based on sample frame of households. At the implementation of this method, problems were encountered in terms of accuracy in the spread of the sample, the result is often debatable in applying the method in the field survey. To answer these problems, a survey of rice productivity has been developed through land survey framework approach or the method known as Area Frame Method. The purpose of this survey was to test the frame methodology for measuring frame rice productivity, and compare the results of the survey area rice productivity using area frames with the household listing conducted regularly by the CBS. The development of this method was expected to be used for problems that arise in the current method by considering the geographical conditions, the type of irrigation and government policies in order to increase production. Frame Area method has been tested in Cianjur (in 2012) and Garut (in 2013) in the province of West Java. Number of Mesh (land area 1,000 m x 1,000 m on the map ) in Garut was 120 Mesh. Each mesh was divided into five plots, so that the number of plots in Garut were 600 plots. Selection of sample plots was done by combining Systematic Random Sampling and Simple Random Sampling. The results of the trial method in the area of Garut showed that the productivity of upland and lowland rice were statistically significantly different as well as there were differences in the productivity of irrigated and non-irrigated lands, and there was no difference in the productivity of paddy land as recommended by the government with the conventional. However, the results of statistical tests on rice productivity of Area Method with the official method of CBS in Garut were not significantly different. This may imply that the sample selection method for measuring current productivity (CBS Method) can still be used, but it needs refinement to make the distribution of the samples stratified by altitude, stratification by type of irrigation and by the involvement of farmers who joined a government program

Abstract

Integrated Crop Management (ICM) of maize has been disseminated since long time in all production centers in Indonesia, including Gorontalo. However, the application at the farmer level has not been optimal so that it has not yet expanded. This study aims to measure the  adoption rate of the components of maize ICM technology, and to identify socio-economic factors that affect the application of maize by farmers in Gorontalo District. The study was conducted on lowland dryland agro ecosystem in Tibawa Subdistrict and highland dryland agro ecosystem in Bongomeme Subdistrict, Gorontalo District. Site selection was done purposively with the consideration that the district  and sub-district were maize production centers, and had implemented various programs to increase maize production with the application of ICM from various government agencies. The survey was carried out in February-May 2015. The adoption rate of maize ICM component by respondents farmers used the weighting (score). Socio-economic factor analysis methods that influence the application of maize ICM using logistic regression model. The results showed that the accessibility of farmers to the supporting sources of farming such as capital (credit), market, and technology sources significantly affected the adoption of ICM technology. Steps that can be taken to improve farmers access to credit in formal financial institutions (banks) include providing flexible credit scheme, easy, not procedural, and not burdensome. Increased access of farmers to the source of technology can be done through increased frequency of extension, the implementation of technology dissemination that reaches more farmer groups and farmers.

Abstract

Information on characteristics related to drought tolerance is particularly important for improving hybrid maize yield. The present study was conducted with 62 genotypes involving tolerant, moderate, susceptible and very susceptible, for post flowering drought tolerance of hybrid maize. An experiment was conducted to determine the characteristics association between grain yield and its components and their direct and indirect effects to the yield. The research was arranged in a randomized completed block design with three replications. Drought stress treatment was started from flowering (50 days after planting, dap) until milk-dough stage (80 dap). The result indicated significant and positive association of grain yield with plant height, ear position height, stalk diameter, leaf area, leaf angle, the percentage of leaf senescence, leaves rolling score, ear length, ear diameter, number of grain/ear and shelling percentage were correlated with the yield under drought stress. Grain yield was strongly correlated with plant height, leaf area, ear length, ear diameter, and shelling percentage. Indirect effect on grain yield under drought conditions were found for the following parameters: stalk diameter, leaf angle, percentage of leaf senescence, leaf rolling scores and number of seeds/ear.

Abstract

Efforts to increase the amount of livestock-crop integration adopter needs agricultural extension support and powerful institutional support through technology transfer to farmers. This research was aimed to determine causal correlation between technology level, institutional support and agricultural extension’s role against the adoption level of livestock-crop integration. This research was conducted from 15th February - 31th March 2013 in Sadangkulon, Kebumen Regency. The used method in this study was structured survey method. Respondents were taken as much as 31 people using sample random sampling, as much as 50% from each farmer group. Variables which measured in this study were integration technology level, agricultural extension role, and adoption level of livestock-crop integration. Data were analyzed using path analysis to estimate the coefficient of linear structural equation which has a causal correlation by SPSS tools. The research result showed that the contribution of exogenous variables (technology level, institutional support, and agricultural extension role) simultaneously affecting the adoption level of livestock-crop integration of 72,5% (P < 0,05). Partially, the adoption level of livestock-crop integration was directly affected by the mastery level of technology (16,4%), institutional support (4,7%), and agricultural extension role (13,4%). Based correlation analysis showed that the correlation between exogenous variable have a positive and significant correlation (r12 = 0,580; r13 = 0,703; and r23 = 0,427). Based on the research result, that mastery level of technology, institutional support, and agricultural extension role had a causal correlation against the adoption level of livestock-crop integration.

Abstract

Major constraints and problems associated with postharvest handling of fresh banana are short shelf life and lack of proper postharvest handling. The purpose of this study was to evaluate fruit quality and shelf life under MAP packaging, with or without KMnO4. This research was conducted between May-August 2013 at the laboratory of food processing and agricultural product, Bogor Agricultural Institute. The data obtained were analyzed with analysis of variance (ANOVA), if the results were significant at 5%, then further test was carried out with Duncan test. The results indicated that the shelf life of bananas packaged in White Stretch Film (WSF) with KMnO4 (MAP active) at 28°C could be stored for 10 days and comparable to 6 days without KMnO4 (MAP passive), and the shelf life of fruit packed in MAP active at 15°C could be stored for 24 days and comparable to 16 days for MAP passive. The 3 factors interaction were significant at different levels of starch content at 6th day, whereas total soluble solids (TSS) was significantly different at 2nd day of storage. MAP active treatment could delay starch content degradation and TSS when compared to passive MAP.
