Published: February 2021

Abstract
The location of the experiment was in the agro-ecosystem rainfed ricefield, Nogosari, Boyolali from June 2017 to September 2017. The research consisted of a survey of technology components commonly applied at the farmer level as well as demonstration plots of technology components in accordance with the integrated crop management of palawija (composite corn and local peanuts). Farmers’ understanding of the cultivation technology of peanuts and corn were very high. The yield of ubinan of Boyolali local peanut monoculture was still higher in farmer dosage (7.5 tons / ha) compared to the recommendation from Center for Agricultural Technology Studies (CATS) of Central Java. The yield of local peanut intercropping composite corn was higher (6.1 ton / ha) compared to the recommendation of CATS (5.0 ton / ha). The yield of monoculture corn cropping is 3.6 tones / ha at recommended dosage treatment and Provit A variety is 4 tons / ha. Meanwhile, the yield of corn in intercropping was experiencing crop failure. Thus, the intercropping pattern of peanuts and composite corn can be accepted by farmers and can develop in this area if assisted by dissemination in the form of demonstration plots in rainfed agro-ecosystems ricefield.

Abstract
Drying and storage of agricultural products are often related to heat transfer processes, both within the material and between the material and its environment. Thermal diffusivity is one of the thermo-physical properties related to the heat transfer processes in the material. This study aims to measure the thermal diffusivity of shelled corn, milled corn passed mesh 6, milled corn passed mesh 8, and milled corn passed mesh 16 (corn flour) fed by an axial heat source of 50 °C and 70 °C. The temperature sensors LM35 were used to gauge temperature history and were placed at 9 points in the test cylinder. The thermal diffusivity is then estimated from the temperature distribution data using numerical method. We found that the thermal diffusivity of shelled corn, milled corn passed mesh 6, milled corn passed mesh 8, and milled corn passed mesh 16 (corn flour) are (1.35, 1.38, 1, 69, and 2.30) x10−7 m2/s, respectively, at axial heat source of 50 °C and (1.39, 1.42, 1.72, and 2.36) x10−7 m2/s, respectively, at axial heat source of 70 °C. The smaller the bulk density and the larger the heat source provided, the higher the thermal diffusivity.

Abstract
Crop production and environmental sustainability were threatened by environmental issues such as global warming, climate change and land degradation. Rice is a staple food of more than half of the world’s population and the most important source of greenhouse gas (GHG) emissions. Rice production accounted for 36% of total emissions from agriculture. The use of organic material management in paddy fields is a potential to support sustainable agriculture. Biochar is reported to enhance soil carbon sequestration and soil productivity. This study aimed to know the effect of combined compost with biochar application on rice yields and greenhouse gas emissions in rainfed rice fields. The research was conducted for 3 years at research station of Indonesian Agricultural Environment Research Institute, Pati-Central Java. CH4 and N2O emissions were measured using close chamber method. We used combined compost with rice husk biochar for organic fertilizer, namely Biocompost. The results of this study indicated that the application of combined compost with biochar in each planting season improved the grain yield by 17% and reduced global warming potential (GWP) by 5% compared to conventional practice. The combined compost with biochar application in paddy fields has the opportunity as GHG mitigation efforts on rice production.

Abstract
Jakarta as a metropolitan area has rice fields spread across three urban areas. The rice marketing was usually conducted directly over harvest time, either to collectors who come to the harvest location or sell them to Subang or Indramayu. The aim of the study was to examine rice profitability and marketing in Jakarta. The study was carried out in three regions of Jakarta, namely North, West and East of Jakarta, through survey method. The respondents were 46 farmers with direct interview techniques. The profitability of rice farming was analyzed by using cost and revenue analysis, while rice marketing was analyzed by using qualitative descriptive. The results showed that rice farming in Jakarta was still profitable with the R/C ratio greater than one. The marketing chain of rice in Jakarta was generally very short. The farmers mostly sold the rice directly to large traders (Jakarta-Outside Trader; 85%), only a small proportion (15%) sold to regional collectors. As much as 90% of the grain was sold to the traders and 10% was used as seed or consumption. The selling price of rice was determined by traders based on quality of grain. The non-hulled rice price ranged Rp 4200-4500 per kg.

Abstract
Climate risk in agriculture indicates the potential of climate-related hazards to impact coffee production and quality negatively. Coffee production has decreased due to changes in temperature, more extended droughts, and increased pests’ invasion. Coffee agribusiness is demanded to respond to the increasing need for Climate-Smart Agriculture (CSA). As a CSA model, coffee cattle integration offers farmers risk management strategies and options to adapt to climate change. However, the effectiveness of its implementation is still low due to technical and institutional constraints. The study’s objectives are to analyze constraints to implement coffee cattle integration as a CSA model and formulate strategies to implement it. The analysis method used Interpretive Structural Modelling. CSA implementation constraints include input, labor, knowledge, technology, capital, and farmer institutions in crop and livestock production. Strategies for implementing coffee cattle integration, as CSA practice, is carried out in a hierarchical stage. It starts with developing a support system to improve agricultural support policies, promote public-private partnerships, and support community assistance and facilitation center, followed by the increasing availability of capital through credit farm.

Abstract
The aim of this research was to detect adulteration in palm sugar by coconut sugar using FT-NIR spectroscopy with two chemometric methods namely partial least squares regression (PLSR) and principal component analysis (PCA). The absorbance spectra were taken using the FT-NIRFlex-500 Solid. Several spectral pre-processing methods used were the 1st Savitzky-Golay Derivative, Normalization, Standard Normal Variate (SNV), Multiplicative Scatter Correction (MSC), and Baseline. Coconut sugar as adulterant with various concentration ranging from 0 to 100% were added to the palm sugar. A total of 77 spectra of pure and adulterated palm sugar samples were divided into two groups in which 51 samples used for developing calibration model and 26 samples used for developing prediction model. The spectral obtained were pre-processed and analyzed using The Unscrambler X version 10.4. The best transformation of PLSR was MSC with coefficient of determination (Rc2) of 0.93 and the root mean square error (RMSE) of 0.07 for calibration. By using prediction data sets, the model resulted in coefficient of determination of prediction (Rp2) of 0.91 and a root mean square error of prediction (RMSEP) of 0.09. Based on this result, FT-NIR spectroscopy combined with chemometrics is a promising method in food authentication.
