Design of Paddy Field Water Level Multi Censor
Abstract. Water conservation for field irrigation is an important key to reducing environmental effects from paddy cultivation. In the AWD (Alternate Wet Drying) method, the rice field is alternately flooded and non-flooded, water height is always measured to adjust with AWD recommendation. This method proved for reducing water usage without decreasing yield. With recent development from IoT Cloud platform, sensors can interface directly to cloud systems and store much data so it can be downloaded and processed later. In this study, electronic water height multiple sensors based on infrared technology is equipped with solar panel and Li-Ion battery storage designed with a compact form. Communication from sensors to master done by radio wave. Power saving method which turnoff sensors and radio power in the standby condition can conserve battery to stand the power without sunlight 11.6 days compared to 3.2 days in non-power-saving design. Battery voltage and water level reading from each sensor is uploaded to Think Speaks cloud IoT dashboard, this data can be analyzed later for other purposes
ANALISIS DAMPAK PENGGUNAAN PUPUK NPK LODRIN TERHADAP PRODUKSI DAN EFISIENSI USAHATANI KAKAO
No full textCocoa has been developed in various regions in Indonesia. In developing cocoa farming, farmers still face the problem of low productivity, efficiency and quality of seeds. This is partly due to not using the right fertilizer. This study aims to analyze the effect of NPK Lodrin fertilizer use on the efficiency and income of cocoa farming in Gorontalo. The study was conducted in several Gorontalo cocoa production centers, namely in Gorontalo District and Pohuwato District in 2016. Data collection was conducted by survey method with questionnaires or structured questionnaires for 59 cocoa farmers. Respondents were farmers who used Lodrin NPK fertilizer and farmers who did not use Lodrin NPK fertilizer. The selection of respondents was carried out by stratified random sampling technique. The farming efficiency analysis method uses the Cobb-Douglas stochastic frontier production function model. Financial farming analysis was carried out to determine the level of cocoa farming income with the use of Lodrin NPK fertilizer. The results showed that the use of Lodrin NPK fertilizer significantly affected the increase in production, efficiency and income of cocoa farming in Gorontalo. The average level of farm efficiency both technical, allocative and economic efficiency of cocoa farmers using Lodrin NPK fertilizer is higher when compared to farmers who do not use Lodrin NPK fertilizer. The factors that influence the inefficiency of cocoa farming are farmer education and institutional factors, namely the frequency of counseling, participation in farmer groups, access to credit and technology assistance. The use of Lodrin NPK fertilizer increases the income of cocoa farming, as evidenced by the value of the R / C ratio and the value of return for higher production factors of farmers who use Lodrin NPK fertilizer

A farmer data-driven approach for prioritization of agricultural research and development: A case study for intensive crop systems in the humid tropics
No full textContext: Intensive rice-maize sequences in Southeast Asia can include up to three crop cycles per year. Indonesia is the third and fifth largest rice and maize producing country worldwide, and domestic demand for both crops will increase in the future. Novel, cost-effective and less time-consuming approaches are needed to identify causes of yield gap at national level. Objectives: Here, we propose a farmer data-driven approach to prioritize investment in agricultural research and development (AR&D) programs. Methods: We collected data on yield, management practices, and socioeconomic variables from 1,147 smallholders’ fields in intensive rice and maize cropping systems, from 2017 to 2018, across ten provinces in Indonesia, which include a wide range of landscape positions (upland, lowland, tidal), water regimes (irrigated and rainfed), and cropping intensities (from single to three cycles per year on the same piece of land). Separate data were available for each rice and maize cycle included in the annual crop sequence. We used conditional inference trees, random forest regression, and comparisons among high- versus low-yield fields to identify key agronomic and socioeconomic factors explaining yield variation. Results: For a given field and crop species, there was a significant positive correlation between yield in one season and that in subsequent seasons. In contrast, there was poor correlation between rice and maize yields in cropping systems including both crops. Socio-economic factors such as years of farming experience and access to extension services and inputs explain variation in average yield gap across provinces. In turn, agronomic factors such as nutrient input rates, splits and timing, establishment date, and pest control, explained yield gaps in farmer fields. Overall, these findings were not consistent with expectations from local researchers about on-farm yield constraints. Conclusions: Our study shows that a modest investment to gather farmer survey data, together with robust spatial frameworks to guide data collection, proper statistical methods to analyze the data, and crop modeling to estimate yield potential, can help identify yield constraints for areas representing millions of hectares of rice and maize. Significance: Our study provides useful information for guiding investments in AR&D programs at national and sub-national level for improving crop production by closing current yield gaps.Fil: Rizzo, Gonzalo.
