Published: January 2022

The highlands in Central Java have a major contribution to meet the national demand for vegetables. However, competition for these lands by non-agricultural sectors or for the production of other agricultural commodities could lead to a decline in vegetable production. The research aimed to spatially analyze the land suitability and availability for highland vegetable commodities. It also aimed to analyze the land potential for the development of vegetable commodity areas. The research was carried out in Banjarnegara and Wonosobo Regencies, at an altitude of more than 700 meters above sea level, from July to December 2020. The methodology used was Multi-Criteria Decision Making with Analytical Hierarchy Process structure and map overlay, using ArcGIS ver. 10.5. The results showed that land which is suitable for the highland vegetable commodities was at 33.52%, it was dominated by a class of moderately suitable (S2). Furthermore, the suitable and available land for vegetable cultivation covers an area of 16.03 %. Finally, there were 9,911.2 hectares of land that had not been optimally used and had the potential to become a development area for highland vegetable commodities in the future.

Authors: Rohmah R S , Widiatmaka  , Lubis I
Published: January 2022

Pandeglang Regency is designated as the agricultural center of Banten Province. Dedicating a specific area to a protected agricultural area often faces problems of not considering the population growth and food needs. Therefore, this research aims to evaluate the spatial pattern and allocation of the agricultural area based on the comparison between spatial planning policy and land-use model on the current trend in 2031 using CA-Markov model. This research uses remotely sensed data from SPOT satellites in 2006, 2012, and 2018 as the base for the 2031 model. The result shows that the number of paddy fields in Pandeglang fluctuated from 2006 until 2031. In 2031, the paddy field is predicted to increase by around 5%. This increase hasn’t been able to keep up with the population growth, as the increase of settlement area exceeds the paddy field at 27%, so that the ratio is around 1:5. The protected agricultural area policy hasn’t been implemented thoroughly, leaving most of it at the risk of conversion. Recommendation towards this challenge and the planning policy is headed towards preserving environment and agricultural area by properly allocating and considering the pattern and rate of urban growth to achieve better food security and sustainability.
Recent Development in Spatial Planning after the Omnibuslaw Job Creation
Authors: Amhar F. , Darmawan M.
Published: January 2022

The Omnibus Law on Job Creation has been ratified. This law is expected to increase investment in Indonesia. The question is, to what extent will this law impact spatial planning and ultimately on environmental management. For this reason, the texts of the old law and the new law are juxtaposed. The research method used is a comparison of legal texts, which is complemented by analysis of samples of various spatial maps and field visits. The findings of this study are as follows. The detailed spatial planning plan is now sufficiently regulated by a regent/mayor regulation. Approval from Regional Parliament (DPRD) is no longer required. The existence of a large-scale map of 1: 5000 is also no longer necessary. If Detailed Spatial Plan (RDTR) 1: 5000 is not yet available, the General Regional Spatial Plan (RTRW) 1: 50,000 map can also be used as a basis for licensing. Unfortunately, to shorten the process of determining the Spatial Plan, now the supervision of the Geospatial Information Agency is only voluntary, no longer mandatory. The sampling test on map samples and field visits showed that this change could result in space utilization errors and spatial violations due to map accuracy issues.

Published: January 2022

The availability of water in the reservoirs in the Central Citarum sub-watershed must be sustainable because it is the mainstay of irrigation water, electricity, and drinking water in parts of West Java and DKI Jakarta. This study aims to determine the effect of land cover change on hydrological parameters by simulating the SWAT (Soil and Water Assessment Tool) model. The research area covering an area of 273,240.85 ha, based on observations of Spot imagery in 2019, has a forest cover of 20.16%. The surface runoff calculation shows that the Flow Regime Coefficient (KRA) is very high (128). Based on the simulation with SWAT, the KRA value will be better (79) if the 2019 RTRW is fulfilled. The results of several land cover scenarios show that an increase in the forest area of 10 – 12% will increase infiltration by about 8-9% and reduce surface runoff by about 8%, and groundwater recharge will be better. The flow of the Citarum river fluctuates and fills the Jatiluhur Cirata Reservoir with an average of 800,081,212.0 m3/year. One way to improve the hydrological function is to convert some dryland agriculture, streamlining urban forest plants to obtain a forest area of 37%.
The application of satellite derived bathymetry for coastline mapping
Authors: Dewi R S , Sofian I , Suprajaka
Published: January 2022

There is a gap in bathymetry data in shallow water due to the difficulty in measuring the depth. Meanwhile, to obtain an accurate datum-based coastline, sufficient depth and topography data are required. In the situation in which bathymetry data from the conventional method (sounding measurement) is limited, the bathymetry data resulted from Satellite Derived Bathymetry (SDB) algorithm can be an alternative solution. The SDB is estimated by correlating water depth and the spectral band of images. This research is conducted to develop a method that can be applied for coastline mapping by assessing the capability of SDB. For the integration of all input data, including land elevation and bathymetry data, a gridding method called stacked continuous curvature splines with tension is adopted. Coastline generated from the proposed method was relatively smooth and it was close to the shape of the land feature compared to coastline developed from other data sources such as the national bathymetry data and echo sounding data. From the results, we conclude that the SDB is promising in filling the gap of depth information in shallow water areas. A feasible coastline can be produced since depth information from the SDB model can increase the density of depth information required for generating a coastline model.

Published: January 2022

Water in coastal and estuary areas needs to be investigated as human activities is allegedly decrease their quality. This has led to optical remote sensing for mapping optical water quality using empirical and semi-analytical approaches. Therefore, this study aims to estimate the Total Suspended Matter (TSM) concentration from Medium Resolution Imaging Spectrometer (MERIS) data using a spectral unmixing approach combined with a radiative transfer model. This approach was implemented in the equatorial tropical coastal water, the Berau estuary, Indonesia, by generating a look-up table (LUT) of top-of-atmosphere radiance spectra through the coupled forward models, and the endmembers were selected from the LUT. The spectral unmixing algorithm was employed to the MERIS data for decomposing the image into haze and sediment components. The data were then transformed into images of a constant haze level corresponding to 50 km visibility, and the atmospheric correction was applied. Furthermore, the TMS concentration was retrieved using the inverse semi-analytical Kubelka-Munk model. The result gave overestimated TSM concentration values on clear waters. However, in turbid waters, a lower RMSE was obtained, and the coefficient of determination was higher than in clear waters.

Paddy fields are the most crucial agricultural land-use in Indonesia that supporting national food security. Such lands have been experienced a massive change in their dynamics, specifically in rice production home, West Java. Karawang paddy fields notably become the major victim of land-use change along with rapid economic growth, development, and population pressure. This study aimed to assess paddy fields’ conversion dynamic and how land-use change contributes to this issue in Karawang. Remote sensing techniques and satellite images were used for investigation across the Karawang Regency. Three kinds of satellite image datasets of Landsat 5 TM, Landsat 8 OLI, and Sentinel 2 during the periods of 2009, 2014, and 2019 were analyzed. The results revealed that land-use change impacted paddy fields conversion significantly. Karawang regency lost 16346.77 ha or 8.54 % of its paddy fields throughout the study period. Such farmlands declined by 8639.84 ha (4.51%) and 7706.93 ha (4.02%) between 2009 -2014 and 2014 to 2019, respectively. The conversion of paddy fields to build areas, including road infrastructures, is approximately 14536.21 ha, representing 57.98% of the total paddy fields converted. It concluded that paddy fields had faced massive conversion over the last ten years driven by conversion into buildup areas due to the increased land demand, i.e., residential, commercial, and industrial activities.

Indonesia is located in three collision zones of the world’s three major plates, namely the Eurasian Plate, the Indo-Australian Plate, and the Pacific Plate. As a result of the plate collision, there were many earthquakes in Indonesia. One of the characteristics of the earthquake in this study is an active fault. Active faults are things that can cause earthquakes. The purpose of this literature review is to determine the differences in the accuracy of the Synthetic Aperture Radar (SAR) method with various types of satellites to identify earthquake characteristics. This literature review is limited by analysis of active faults on land using SAR imagery in the territory of Indonesia. Indonesia is located in the equator causes high cloud coverage throughout the year in Indonesian region. The advantages of this SAR image are that it can monitor the earth’s surface without weather disturbances, can penetrate clouds, and can be used during the day or night. The results of this literature review show that to identify the impact of earthquakes with high slip fault sources, medium resolution SAR images can be used (such as using Sentinel-1 imagery), and to identify the effect of earthquakes with low slip faults, high resolution can be used (such as using ALOS-2/PALSAR imagery). Knowing the impact of deformation due to earthquakes can be used to improve disaster preparedness, particularly those caused by earthquakes.

One of the problems in Tesso Nilo National Park is deforestation through the opening of oil palm plantations. This can affect the ecosystem services of Tesso Nilo National Park, one of which is as a producer of water. Water yield is a key component of the attributes and processes that produce water-related ecosystem services. The importance of Tesso Nilo National Park ecosystem services as water producers needs to be assessed quantitatively and visualized to explain changes in land cover to changes in these services. The purpose of this study was to analyze the annual water yield in Tesso Nilo National Park. The model used is the Integrated Valuation of Environmental Services and Tradeoffs (InVEST) water yield model. InVEST is a spatially explicit tool for exploring how changes in ecosystems tend to lead to changes in benefits flowing to people. The annual water yield in Tesso Nilo National Park in 2018 was 5731528155.86 m3 or 2729.52 mm. Water yield is strongly influenced by actual evapotranspiration (AET), mean annual rainfall (MAP), and land cover (LC). The land cover that produced the lowest to the highest water yield was mixed acacia, forest, oil palm plantations, bare land and shrubs.

Published: January 2022

Built-up is artificial land use representing urban-oriented activities according to the sector developed in the aerotropolis, the development concept of city activity centered on the globally networked economy’s airport. The growth of unplanned built-up often caused environmental deterioration. Therefore, the impact of the emerging of a new growth center to the growth characteristic of the built-up requires to be analyzed. This research aimed to examine the growth and spatial distribution characteristics of built-up to mitigate the undesirable impact on the environment in the early phase of aerotropolis in Kulon Progo. The growth was analyzed using the spatial intersection of land use/land cover. The distribution orientation growth was carried out by weighted mean center and spatial standard deviational ellipse. The results demonstrate that annual growth of built-up increased from 55.35 ha per year in 2010-2015 to 69.83 ha per year in 2015-2020. Dryland agriculture was the most land use converted to built-up after aerotropolis era. The direction of built-up growth also shifted from northwest to southwest, and the distance between the airport and the mean center was getting closer. Therefore, land use planning policy need to refer to this pattern changing to preserve environmental sustainability while achieving economic growth.

Published: January 2022

The assessment of tree damage aims to measure the level of tree damage so that the tree damage assessment can measure the level of disturbance to trees so that they can know the condition of the forest and know what happens in the future. This study aims to determine the landscape characteristics in the cluster of health measurement plots in three forest functions (production forest, conservation forest, and protection forest). The stand damage index for the cluster plots was collected, and perform spatial analysis, which included stand damage in the cluster plots based on landscape characteristics (road distance, slope, and elevation). The tendency of damage due to reach from the road tends to damage other stands. Significant damage occurred in conservation forest rather than protection forest and production forest with a percentage value of 98%. Slopes have a reasonably substantial damage effect-the higher the hill, the more damage to the stand. The gradient of 25-40% (steep) has a significant impact on protected forests with a percentage of 85%. Altitude does not matter much where low height causes considerable damage-substantial damage to production forests <500 masl.

Published: January 2022

Climate is the crucial determining component in defining the land suitability class for paddy. The paddy suitability class is expected to decrease as a result of global climate change. This study analyzed land suitability for paddy based on the Representative Concentration Pathways (RCP) 4.5 climate projection scenario of Sukabumi Regency in 2020 and 2032 using the Model for Interdisciplinary Research on Climate (MIROC) 5. The parameters analyzed were precipitation (pr), and near-surface air temperature (tas). The global data was adjusted to local conditions using a bias factor calculated using observed climate data from the Meteorological, Climatological, and Geophysical Agency Station in Bandung. Based on the results of this study, climate (precipitation and temperature) projections for Sukabumi Regency in 2020 and 2032 are classified as highly suitable (S1) for paddy cultivation. The result of this study indicates that there would be no change in the climate suitability class for paddy cultivation in Sukabumi Regency between 2020 to 2032. However, the results of this study also identified a significant numerical decline in precipitation. Therefore, we recommend necessary climate change mitigation and adaptation programs to reduce the future risk of decreasing rice production due to crop failure.

Published: January 2022

Runoff, soil erosion, and sedimentation can be used to assess the watershed condition. GeoWEPP is one of the erosions predictions models that can be used to predict those parameters and also can be used as a tool to arrange watershed management. Cimanuk Hulu sub-watershed is one of the important watersheds in West Java Province, Indonesia, as its function for water resources for Jatigede reservoir. The condition of this sub-watershed is in poor condition because of the high rate of sedimentation in water body. Therefore, we use the GeoWEPP model to assess runoff, erosion, and sedimentation in the Cimanuk Hulu sub-watershed. The model is also used to arrange the watershed management scenario. The input data are climate data, soil characteristics, land cover management, channel characteristics, digital elevation model, soil and land cover map. Land cover types were classified using Google Earth Engine (GEE) with SmileCART algorithm. Soil samples, land cover management, and channel characteristics were collected from the field survey. The result showed that runoff value in the existing condition is classified as a high class that affected higher soil erosion and sediment yield compared to tolerable soil loss in the Cimanuk Hulu sub-watershed. Simulation of watershed management showed that scenario 3 is the best in reducing the runoff, erosion, and sedimentation in the Cimanuk Hulu sub-watershed.

Authors: Abeuov S K , Shoykin O D , Kamkin V A
Published: January 2022

The authors of the article presented a visual technique for programming the yield of potato tubers by using mathematical models of the relationship with the chemical composition of the soil. The content of N-NO3 and P2O5 varied in the range of 14.7-35.0 mg/kg and 37.1-39.0 mg/kg of soil. The increase in the content of these nutrients was accompanied by an increase in the productivity of potato tubers from 1 ha. The results of the study showed that the yield value is closely related to the content of N-NO3 and P2O5 in the soil in the initial phase of crop growth. The verification of the calculation methods showed a forecast error by comparing the actual yield data with the predicted results. The established quantitative indicators with the help of mathematical communication models make it possible to diagnose the value of potato yield and normalize the effect of fertilizers.

The manure contained 0.59% of N, 1.13% of P2O5, 0.14% of K2O, 82.1% of organic matter at pH = 7.4. In field experiments carried out at the experimental field of the Omsk State Agrarian University (Omsk), the cellulose-destroying capacity of the soil and the activity of the enzymes catalase, urease and invertase were studied. The soil of the control variant had a weak cellulose-degrading capacity and was poor in the content of the studied enzymes. The results of the experiments indicate a positive effect of pig manure on the activity of biological processes in the soil. The cellulose-degrading capacity of agrochernozem depended on the dose of manure and the hydrothermal conditions of the growing season. In the period from the first to the third years of manure aftereffect, the intensity of cellulose destruction increased in comparison with the control by 20-90% at a dose of 20 t/ha and by 70-230% at a dose of 60 t/ha. Organic fertilization increased the activity of urease by 34.6-68.0%, by 10.7-14.6% that of catalase and by 5.8-12.2% that of invertase.

Published: January 2022

Drying (dewatering) of plant products is widely used in various technologies of their processing, transportation and storage. Existing dewatering processes and equipment are very diverse in design and application; their technical and economic performance also varies significantly. The effectiveness of the dewatering process of vegetable raw materials depends on the range of initial and final humidity and a number of physical, mechanical, chemical and other properties of the product, the drying method, technology and technical characteristics of the equipment. characteristics of the equipment. It is particularly difficult to ensure efficient, relatively low-energy drying of grain products, the seeds of which contain moisture in a bound form and are separated from the external environment by a dense seed shell. Currently, the volume of drying and processing of such seeds is increasing and amounts to millions of tons per season. Dried seeds are used to make flour, food additives, spices, medicinal oils and other natural products. The article studies the ways to reduce energy consumption in the main drying method-convective dewatering of commercial grain with low initial humidity. It is shown that the injection of small doses of microwave energy into the drying process - 1-5% of the total convective heating power - can reduce the overall energy intensity of the process by 25-27%.

In the context of the country’s growing self-sufficiency in foodstuffs, including potatoes, commodity producers need to purchase potato harvesters and devices. The choice of potato harvesting equipment should meet the needs of agricultural producers (potatoes) while contributing to the improvement of agricultural performance. In this situation, enterprises are faced with the problem of choosing potato-harvesting equipment: cheap but low in productivity, or expensive but high-tech. To substantiate the choice of using machines for harvesting potatoes, it is possible to use the method of expert assessment, which allows choosing among a variety of alternatives, based on the preferences and justifications of experts. The use of the mathematical apparatus makes it possible to compare various physical characteristics by reducing them to a dimensionless scale. As a result of studying the most common trailed potato harvesters, the KKP-2M trailed harvester possesses the optimal ratios of the cost of the machine, productivity and quality of the resulting product. Trailed potato harvesters at a lower price have technical parameters that are not much inferior to self-propelled machines. This conclusion is confirmed by such methods as “Score table” and “Polygon for alternatives”. The first method provides a mathematical justification and the second one allows visualizing the resulting solution.

The BioStreamer 165HD is equipped with such feature as flexible incubation environment tuning according to its technology of embryo feedback. The sensors control the temperature inside machine by using the temperature of egg shells. Also there are sensors which can monitor the humidity level by controlling and predicting the humidity loss of each egg lot and using the narrow-hatching window technology. The incubators are managed by controller and connected to one computer network. The eggs are set to cellular structure incubation tray. The pulsators are equipped with five wide blades to ensure the required air flow rate. In addition, the roof vents have been improved. The power of the heating elements has been increased, which provides a quick heating time for all eggs at the beginning of the incubation cycle. The larger diameter of the cooling coil creates a wider overall cooling surface. As a result of the research, it was found that the use of the BioStreamer incubator made it possible to increase the hatchability of eggs, to carry out the simultaneous hatching of young brood, reducing the hatching by 5.5 hours, to increase the yield of conditioned young chickens by 0.9% and its quality, to obtain a greater amount of meat products from broilers: the average weight of chickens increased by 2.7 per cent, the safety of brood - by 3.6 per cent.

The release of good-quality and safe poultry products depends on the sanitary condition, compliance with preventive measures and the development of technologies aimed at improving the safety of the products. Microbiological studies and meat quality indicators were determined using standard methods. A method of cooling in 0.01% solutions of HIT AseptoDes has been developed to control the contamination of the cooling medium and prevent microbial contamination of the surface of poultry carcasses. It has been shown that to reduce microbial contamination and decontamination of the surface of carcasses from Salmonella, 0.02% solutions of the agent can be used with a cooling time of 25 minutes and 0.01% solutions with a cooling time of 35–40 minutes. The quality indicators of meat of carcasses chilled with solutions of the studied product, in comparison with carcasses chilled in ice water, do not differ significantly, with the exception of the acquisition of the surface of the carcasses of a paler color. It was found that after 6 hours of storage, the presence of a residual amount of peracetic acid in washes from carcasses was not detected.

The studies on the comparative assessment of soybean varieties of Siberian breeding performed in 2017-2019 in the sub-taiga zone of the West Siberian region showed that the duration of the growing season of soybeans depended on the biological characteristics of the variety and weather conditions. SibNIIK 315 variety was characterized by the shortest growing season – 96 days, while Cheremshanka variety had the longest – 108 days. Sibiryachka and Eldorado soybean varieties were the second in terms of early ripening (102-103 days). In wet 2017 and 2018, the growing season of the studied varieties was delayed by 9-15 days compared to warm and drier 2019. The yield of soybean grain was influenced by the characteristics of the variety and weather. On average, for three years of study, the highest grain yield – 2.65 tons/ha was obtained from Sibiryachka variety. SibNIIK 315 took the second place in terms of yield. In terms of grain quality, Zolotistaya and SibNIIK 315 with protein content of 32.6 and 32.2%, respectively, were the best. The protein content of Sibiryachka variety was less – 31.5%, but higher compared to Eldorado and Cheremshanka varieties.

The article proposes recipes for baking a bakery product with the introduction of new food additives: iodized salt, iodo-casein, amiton. The influence of iodine-containing additives on the nutritional and biological value of bread, as well as on their quality, has also been studied. It was found that the introduction of iodine-containing additives caused an increase in the volume yield of bread. So, namely, the introduction of iodized salt increased the volume yield by 12.6 %, iodo-casein caused the increase by 17.6 % and when introducing of the parameter was 12.5 % higher than the control. Bread with iodine-containing additives is a complete food product with a high nutritional value: 100 g of bread satisfy a person’s need for proteins by 8.9 %, for fat by 2.3 %, for carbohydrates by 14.4 %, and the person’s need for iodine. When daily consumption of 200-250 g of bread with iodo-casein, the iodine content will be 78-97.5 μg, or 52-65 % of the recommended physiological norm. Bakery products with iodine-containing additives are a complete food product with a high nutritional value. Therefore, to enrich bakery products with iodine, then iodo-casein, iodized salt, amiton, which contain the amount of iodine necessary for a person, can be recommended as iodine-containing additives.
