Moisture content is one of important soil characteristics in agricultural systems and is often needed to determine other soil characteristics. Gravimetric method is widely used to measure soil moisture content. Although the result is quite accurate, however it is very time consuming. In this research, soil moisture content of arid field has been analyzed by image processing method using webcam and infrared webcam as the image-captured devices. This research aimed to estimate soil moisture content from images captured by webcam and infrared webcam and to define the most appropriate visual properties as the soil moisture content prediction parameter. Soil samples used in this research was from arid field of Gunung Tugel Village Banyumas Regency. Thirty samples of arid field soils were collected using soil ring samplers in 5 cm of soil depth. All samples were wetted until they reached a saturated condition. After that, the samples were stored for 30 days under room temperature condition until the soils became dry. Everyday the weight of each soil was measured and the images were captured by using webcam and infrared webcam. The images were then extracted by using image processing to obtain visual parameters such as RGB index as well as HSI colour and texture feature. Each of the visual parameters was then determined its correlation with soil moisture content and the R2 of the correlations. The final step of the analysis was calculating the mean percentage error (MPE) of the moisture content estimation. A visual parameter which has the least MPE would be used as the prediction parameter. The results of this research showed that soil moisture content of arid field could be predicted by using visual parameters from images captured by webcam and infrared webcam. Intensity of the soil images captured by infrared webcam resulted prediction error lower than that by webcam.

Rice-field rat (Rattus argentiventer) is a rodent that has a high level of productivity. These animals attack rice plants from the vegetative to the generative phase. This research aimed to analyze and to predict the accuracy of the use of owls with mathematical equations model in Kebokura and Lebeng villages, Sumpiuh district. Lotka - Volterra and Competitive Lotka-Volterra models were used to predict the population dynamics of Owl (predator) and rice-field rats (prey), then Runge - Kutta numerical method was applied to analyze the population dynamics of predator and prey at a certain time. The results of the analyses using the Lotka – Volterra, Competitive Lotka - Volterra equations and simulation data, each graph data showed that the rats’ population was able to be maximally suppressed. Based on the analysis result, started with 24 owls and 1,689 rats, the rats’ population could be suppressed to 104 using Lotka – Volterra, and to 176 using the Competitive Lotka – Volterra model. Then in the first and second simulation, started with 50 and 100 owls and 1,689 rats, analysis using Lotka – Volterra and Competitive Lotka – Volterra showed that the rat population could be suppressed to as much as 126, 188 and 145, 189, respectively. Based on the analysis, it could be concluded that use of Serak Jawa owl strategy was able to reduce and stabilize the rat populations. Furthermore, the higher population of owls can prevent the population explosion of rats and can suppress the rat population to a lower number.

Penurunan luas lahan terbuka akibat permukiman berdampak pada penurunan pengisian air tanah dan meningkatnya laju aliran permukaan. Teknologi Pemanen Air Hujan (PAH) dan Drainase Vertikal (DV) menjadi alternatif solusi. Selain aspek lingkungan, air hujanmemenuhi syarat kualitas air minum. Tujuan pengabdian masyarakat ini adalah meningkatkan pengetahuan mitra perihal konservasi dan teknologi sumber daya air serta replikasi dalam skala rumah tangga. Implementasi program pengabdian masyarakat dilaksanakan di Desa Kaliori, Kabupaten Banyumas, Jawa Tengah. Metode pelaksanaan meliputi pengumpulan data dasar kondisi masyarakat, penyuluhan, diseminasi teknologi, dan evaluasi program. Diseminasi teknologi dilakukan di rumah salah satu mitra yang berada di kawasan Tempat Pembuangan Akhir (TPA) Kaliori. Setelah implementasi program, pengetahuan mitra tentang teknologi yang didesiminasikan meningkat. Pada saat program dijalankan, kinerja teknologi PAH dan DV belum bisa diaplikasikan karena kemarau panjang. Hal ini menjadi salah satu faktor yang menyebabkan mitra belum memiliki keinginan kuat untuk mereplikasi teknologi yang diperkenalkan. Peningkatan pengetahuan mitra tentang pentingnya air hujan bagi pemenuhankebutuhan rumah tangga dan pengisian air tanah diharapkan menjadi budaya baru bagi mitra dalam konservasi sumber daya air.

AbstractArtificial lighting given in plant-factory planting system is inseparable from uniformity problem. Spatial variation in the catch of light (radiation) will occur due to the position of the plant against the lamp. The purpose of this research was; a) to determine the relationship between biomass growth and the intensity of artificial irradiation in plant-factory systems, and b) to apply the mechanical model of plant growth basedon radiation interception and temperature. Six boxes containing red spinach plants were placed on plant factory system in the form of two racks (each rack is placed 3 boxes). In each box, intercepted light was measured and then converted to radiation value. The air temperature in plant-factory space was measured during growth to harvest. Observations showed that there was a difference in light interception in plantfactorygrowing spaces that caused variations in plant biomass growth. Mathematical models were used to predict the relationship between light interception and biomass growth. This research concludes that the variation of light occurring in plant-factory planting cannot be ignored, as this leads to markedly different plant-end biomass differences. Modeling can be applied to design optimal lighting to improve plant biomass.AbstrakPencahayaan buatan yang diberikan dalam sistem penanaman dalam ruang (plant factory) tidak terlepas dari masalah keseragaman. Variasi spasial dalam tangkapan cahaya (radiasi) akan terjadi karena posisi tanaman terhadap lampu. Tujuan dari penelitian ini adalah; a) untuk mengetahui hubungan antara pertumbuhan biomassa dan intensitas penyinaran buatan dalam sistem plant-factory, dan b) menerapkanmodel mekanik pertumbuhan tanaman berdasarkan intersepsi radiasi dan temperatur. Enam buah kotak berisi tanaman bayam merah diletakkan pada sistem plant factory berupa dua buah rak (masing-masing rak ditempatkan 3 buah kotak). Pada masing-masing kotak diukur cahaya terintersepsi yang kemudiandikonversi menjadi nilai radiasi. Suhu udara dalam ruang plant-factory diukur selama pertumbuhan hingga panen. Pengamatan menunjukkan bahwa dalam ruang tumbuh plant-factory terdapat perbedaan intersepsi cahaya yang menyebabkan adanya variasi pada pertumbuhan biomassa tanaman. Model matematikadigunakan untuk memprediksi hubungan antara intersepsi cahaya dan pertumbuhan biomassa. Kesimpulan menunjukkan bahwa variasi cahaya yang terjadi dalam penanaman sistem plant-factory tidak dapat diabaikan, karena menyebabkan terjadinya perbedaan biomassa akhir tanaman yang cukup tajam. Permodelan dapat diterapkan untuk merancang pemberian cahaya yang optimal untuk meningkatkanbiomassa tanaman.

This study aimed to determine the land suitability for paddy plantation in Semangga subdistrict, Merauke Regency, Papua Province and to identify any treatments that needs to be taken to promote the land suitability classes. The information on land suitability is important to determine the treatment required in land preparation in order to achieve optimal production. Survey was conducted to collect necessary data which includes climate data, nutrient content (N, P, K available), Cation Exchange Capacity (CEC), pH, and toxicity. These data are interpolated within the area of Semangga subdistrict and classified based on the criteria developed by Indonesian Soil Research Institute - Ministry of Agriculture and FAO. Overlay analysis is performed in order to determine land suitability classes and the dominant limiting factor. Criteria for determining the suitability classes was taken from the lowest class of land unit. The results showed that the area of 1% (360.09 hectare) is classified as class of S2wfn, 55.8% (19,495.83 hectare) as class of S3n, 7% (2,431.83 hectare) as class of S3np, 35.3% (12,349.74 hectare) as class N1n, and 0.9% (306.6 hectare) as class of N2f. The finding of land suitability classes and its dominant inhibitory factor can be used then to determine the proper land treatment planning such as fertilization, liming, and drainage system design.

Increased awareness of precision agriculture in water management, requires various ideas and methods for its application in the fields. One idea that can be categorized into precision farming as well as appropriate technology, is evaporative irrigation. Evaporative irrigation is an idea to control the provision of irrigation water based on the direct response of plant water needs, namely evapotranspiration. The objectives of this study were to: (1) examine the theoretical aspects of the evaporative irrigation to be applied to plots of rice fields in a plot of plots with irrigation units, (2) laying out design principles for evaporative irrigation valve closures. The results showed that, theoretically, a controller pipe was needed which would be an indicator for thick water in the plot of rice fields. The pipe controller regulates the opening of the irrigation lid to the plot based on the float-ballast principle. The design principle is carried out by simulating the reduction in the controller water level of the controller which illustrates the decrease in thick water plots. Water depth that is still tolerated for rice growth will be the limit for the provision of irrigation water to the plots. Amount of irrigation water provided is equal to the value of plant water needs in the ongoing rice growth phase. One example of the design of the controller pipe water level to start and stop irrigation is at 117.8 mm water level and 300 mm respectively. The total water needs of one crop-season is calculated to be 625 mm. With the application of evaporative irrigation, the initial conditions of sufficient water do not require the provision of irrigation water until the 31st day. Irrigation water application after that, until harvesting, requires only 477 mm. Giving this water follows the plant water requirements calculated on a day-to-day basis.

System of Rice Intensification (SRI) is known as alternative rice farming for the mitigation of greenhouse gas (GHG) emissions. There are two main gasses emitted from paddy fields, i.e., methane (CH4) and nitrous oxide (N2O). Both of these gases have different characteristics as response on water availability in the fields which is represented by groundwater levels. Global Warming Potential (GWP) is used as an index that allowed comparisons of the global warming impacts of different gases at specific time period to warm the earth and it is equivalent to the value of the potential of CO2. This study aimed to analysis the global warming potential from different water regimes with SRI practices. Achieving the objective, rice cultivation with three water regimes was carried out during one planting season (14 April until 5 August 2016) in experimental plots of Department of Civil and Environmental Engineering IPB, Bogor, Java West. The regimes were continous flooding, moderate and dry regimes, respectively. The results showed that dry regime has the lowest global warming potential than those others regimes. Its potential was 34% and 41% lower than those for flooding and moderate regimes, respectively. In addition, dry regime produced more grain yield. Its productivity was 21% greater than that flooding regime. These results were obtained from specific climate and location. To corroborate the results, further research is needed under different weather conditions and multi-locations.

Groundwater is an important process in the watershed hydrological system. Serayu watershed, the largest in Central Java Province, has bio-physic spatial variability that influences groundwater recharging. The aim is to derive the groundwater potential zone of the Serayu watershed. Five thematic maps used and applied for groundwater potential analysis, were lithology, land use land cover, lineament density, drainage density, and slope gradient. Distribution of Lithology data, Digital Elevation Model (DEM), and Landsat 8 image were analyzed to thematic raster with 1 x 1 km resolution. Weighted index was calculated regarding the relation of five influence parameters then were overlaid and calculated by using QGIS-calculator. Groundwater classified into five categories, namely poor, low, moderate, good, and very good. Based on the final groundwater potential map, 0.02% of 3,727 km2 is poor category, however most of Serayu watershed have moderate to good (48.77 and 29.77 %, respectively). The percentage of very good (10.57%) and low (10.87%) classes were rather similar. Spatial variability of groundwater distribution indicates the complex characteristics of the Serayu watershed, so more serious attention from the perspective of research and management of water resources in the future, is needed. Keywords: Groundwater, Multi-criteria, QGIS, Recharging, Serayu watershed.
