Institutional Innovation of Integrated Cropping Calendar Information System to Support Climate Change Adaptation for National Food Security
Government of Indonesia has set the rice surplus target of 10 million tons in 2014. This program requires integrated and comprehensive efforts of all stakeholders in central and local levels. The policy was set forth in form of Permentan No. 45/2011 and then implemented by the Director General of Indonesian Agency for Agricultural Research and Development (IAARD) through a decree No. 178.1/Kpts/OT.160/I/7/2012 about For- mation of Integrated Cropping Calendar and Climate Change Task Force in each Assessment Institute for Agricultural Technology (AIAT) for whole Indonesia. Additionally, IAARD has developed an Integrated Cropping Calendar Information System as a reference for policy makers in planning food crop management. The information system contains the next planting season estimation at sub-district level, which includes the initial time of planting, disaster-prone areas (flood, drought, and pests/diseases), as well as technology recommendation (varieties, seed, and fertilizer). In order to make an operational standard for AIAT Task Force, the Technical Guideline of Integrated Cropping Calendar and Climate Change is imperative. This article contains the summary of the technical guideline for AIAT Task Force in support of Permentan No. 45/2011 and climate change adaptation for food security. An implication of implementation of the AIAT Task Force is an important part in improving the content of Integrated Cropping Calendar Information System that fits the needs of farmers and extension workers in the field in order to achieve the rice surplus target
Sistem Informasi Kalender Tanam Terpadu: Status Terkini Dan Tantangan Kedepan
. The accuracy in determining time of planting is one of determining factors in securing good harvest and increasing yield of food crop. Local wisdom and other conventional ways applied previously in determining cropping pattern are no longer appropriate because of shifting seasons. As a guideline for extension workers in determining cropping pattern and time of planting, Indonesian Agency for Agricultural Research and Development has published information system of integrated cropping calendar to secure national rice production in coping with climate variability and climate change. This paper aims to describe the development of web-based Information System of Integrated Cropping Calendar at a sub-district level. The system is constructed by integrating three sub-systems, namely sub-system data, model and query and can be accessed through the website address at www.litbang.deptan.go.id. The main information that can be obtained from this system is initial estimate of paddy planting time for the upcoming planting season. In addition, the users can obtain information on disaster prone areas such as droughts, floods and pests attack. Other informations are recommended technology for varieties, seed requirement and fertilizers, that be prepared by users prior to growing season period. Therefore, this system needs to be improved for all sub-districts in Indonesia at least three times a year of the beginning of each growing season. The challenges of developing integrated cropping calendar system for the future are: (1) global warming increases unpredictable weather that impacts on the accuracy of planting time estimate, (2) decreases in productivity and yield production which would require an increasingly technological innovation informations, and (3)land conversion and fragmentation of agricultural land resulting in reduction of paddy field area. Maintenance and development of this system are still needed, to improve the quality of data and information in order to meet the user needs
Innovative Methylcellulose-Polyvinyl Pyrrolidone-Based Solid Polymer Electrolytes Impregnated with Potassium Salt: Ion Conduction and Thermal Properties
In this research, innovative green and sustainable solid polymer electrolytes (SPEs) based on plasticized methylcellulose/polyvinyl pyrrolidone/potassium carbonate (MC/PVP/K2CO3) were examined. The MC/PVP/K2CO3 SPE system with five distinct ethylene carbonate (EC) concentrations as a plasticizer was successfully designed. Frequency-dependent conductivity plots were used to investigate the conduction mechanism of the SPEs. Electrochemical potential window stability and the cation transfer number of the SPEs were studied via linear sweep voltammetry (LSV) and transference number measurement (TNM), respectively. Additionally, the structural behavior of the SPEs was analyzed using Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), X-ray diffractometry (XRD), and differential scanning calorimetry (DSC) techniques. The SPE film complexed with 15 wt.% EC measured a maximum conductivity of 3.88 × 10−4 Scm−1. According to the results of the transference number examination, cations that record a transference number of 0.949 are the primary charge carriers. An EDLC was fabricated based on the highest conducting sample that recorded a specific capacitance of 54.936 Fg−1 at 5 mVs−1
