Abstract

Land evaluation is a process of assessing land resources to determine their suitability for specific purposes. This study aimed to evaluate the land suitability for maize (Zea mays L.) in Sipahutar District, North Tapanuli Regency, using a semi-detailed level analysis (1:50,000). The physical and environmental characteristics of the land were obtained from secondary data and analyzed using the matching method, which compared land characteristics with the optimal requirements for maize cultivation. The research area consisted of four land units (I-IV). The results indicated that land unit I fell within the N (unsuitable) class due to the limiting factor of sandy soil texture, that is difficult to overcome. Meanwhile, land units II-IV were classified as S3 (marginally suitable) due to limiting factors such as shallow rooting depth, which significantly affected productivity. These limitations are challenging to address without significant intervention, such as government support or investments from large-scale enterprises. The study highlights the need for targeted land management strategies to optimize maize production in the region.

Abstract

Soil types such as Entisol have low nutrient availability and water-holding capacity. Shrimp waste organic fertilizer and coconut shell biochar can be used to improve the physical and chemical properties of Entisol soil. The purpose of this research was to determine the effect of shrimp waste liquid organic fertilizer and coconut shell biochar on the availability of N, P, and K in the soil for the growth of Pakcoy. The research used a Completely Randomized Design (CRD) with two factors. The first factor was the concentration of shrimp waste liquid organic fertilizer consisting of P0 = 0 mL/L, P1 = 25 mL/L, P2 = 50 mL/L and P3 = 75 mL/L. The second factor was the dosage of coconut shell biochar consisting of B0 = 0 ton/ha, B1 = 10 ton/ha, B2 = 15 ton/ha and B3 = 20 ton/ha. The preliminary analysis parameters consisted of pH H2O, C-organic, N-available, P-available, K-available, N-total, P-total, K-total, and CEC. The research results were analyzed by using Analysis of Variance (ANOVA), and to determine the differences between treatments, a 5% DMRT (Duncan Multiple Range Test) was conducted. The research results indicate that the use of liquid organic fertilizer from shrimp waste with a concentration of 50 mL/L and a dose of coconut shell biochar at 20 tons/ha can increase the organic carbon content in the soil from 0.03% to 0.05%. A concentration of 75 mL/L for liquid organic fertilizer from shrimp waste and a dose of 20 tons/ha for coconut shell biochar can increase the available nitrogen content in the soil from 16.24 ppm to 40.67 ppm. There is no interaction with the height, number of leaves, anda root length of Pakcoy plants.

Abstract

The increasing demand for land has resulted in the reduction of potential agricultural land. Land suitability evaluation is an effort that can be made to determine the capacity of land for a particular commodity or crop development through various standardized land use requirements. East Java as a region that supplies vegetable commodities on a national scale still requires various efforts to optimize land use. This research aimed to identify areas that have potential land for cultivating potatoes. This identification was carried out using remote sensing which was then cross-checked with actual potato production data from each region in East Java Province. Based on data processing that had been carried out, in general, East Java is dominated by areas with land suitability classes in class N (not suitable), S3 (marginally suitable), and S2 (quite suitable). Lowland areas are dominated by class N (not suitable) because the land characteristics do not meet the requirements for growing potato plants. Meanwhile, the S3 and S2 classes are spread across the highlands with land units that meet the requirements and characteristics of land for cultivating potatoes. Efforts for classification, conservation, and so on become a unity to optimize and increase potato production in each region.

Abstract

The decreasing land area for coffee cultivation in Indonesia has led to a reduction in coffee production. The availability of land with potential for coffee plantation is also decreasing. As a consequence, coffee is cultivated on less fertile lands, such as lands dominated by clay fraction. This land generally has a low pH so that the nutrient content is more absorbed in Al and Fe which react in an acidic environment. Furthermore, heavy texture of soil also inhibits root growth, making it difficult for plants to absorb nutrients. In this study, biopore infiltration holes were used as a solution to improve acidic soil with a dominant clay fraction. The research was conducted at Agrotechnopark Jatikerto, Malang Regency and the soil analysis was conducted at the Soil Chemistry Laboratory, Faculty of Agriculture, University of Brawijaya during 2020-2022. This research was conducted experimentally with a group randomized design. There were four treatments in this study, namely 1) control/no biopore, 2) 30 cm empty biopore, 3) 30 cm biopore + 2.12 kg compost fertilizer, and 4) 30 cm biopore + 1.05 kg goat manure fertilizer.  The results showed that biopore infiltration holes added with compost or goat manure fertilizer were able to increase pH, soil organic C, CEC, BS, and total N-P-K nutrients. Furthermore, the increase in organic C and total N-P-K nutrients in the study area was also directly proportional to the increase in chlorophyll content and coffee production. The increase in chlorophyll content and coffee production is a result of the increase in chlorophyll content and coffee yield.

Abstract

Soil serves as a medium for the absorption of greenhouse gases due to its organic carbon content; however, its capacity to absorb greenhouse gases has been declining. One of the contributors to carbon dioxide (CO2) emissions in agriculture is soil microorganism respiration, while high nitrogen (N) loss is attributed to its mobility. The application of biochar has the potential to reduce greenhouse gas emissions and improve soil quality. This study aimed to analyze the effects of different types and doses of biochar on reducing CO2 emissions, increasing nitrate levels, and enhancing microorganism populations. The research was conducted in the Soil Laboratory of Agroecotechnology, Malikussaleh University, using a completely randomized factorial design (CRD) with two treatment factors. Factor 1 was the type of biochar: (J1) rice husk biochar, (J2) giant bamboo biochar, and (J3) sweet corn cob biochar. Factor 2 was the biochar dosage: (D0) 0 tons ha⁻¹, (D1) 10 tons ha⁻¹, (D2) 20 tons ha⁻¹, (D3) 30 tons ha⁻¹, and (D4) 40 tons ha⁻¹. Parameters analyzed included CO2 emissions, soil nitrate levels, and microorganism populations. The results showed that rice husk biochar effectively reduced CO2 emissions from soil microorganism respiration to 4.08 kg CO2 ha⁻¹ hour⁻¹, increased soil nitrate levels to 8.14 ppm, and enhanced microorganism populations. The optimal biochar dosage was 30 tons ha⁻¹.

Abstract

Climate is an important factor which influences the growth and productivity of oil palm. The current oil palm cultivation system is vulnerable to climate change. For example, there was a decline in global oil palm production in 2015 due to ENSO, particularly affecting Southeast Asia. Extreme drought causes oil palm plants to experience water stress, while forest fires due to drought inhibit the photosynthesis process. A comprehensive study of the Systematic Literature Review was carried out using bibliometric analysis, systematic review and Meta-Analysis (PRISMA) methods, using the search engines Scopus and ScienceDirect with the keywords “palm AND oil AND production AND climate AND change”, “impact AND climate AND change AND coconut palm AND oil”, “palm AND oil AND adaptation AND climate AND change”, “palm AND oil AND mitigation AND climate AND change”. A thorough scientific literature review obtained 1331 papers from Scopus and ScienceDirect. Out of these, only 26 articles were selected for further examination. Based on the literature, there are several strategies for increasing oil palm productivity in the era of climate change. These strategies can be done through agronomic management, providing fertilizer from oil palm biomass, and maintaining irrigation for water availability. This literature study provides recommendations for strategies for increasing oil palm productivity in the face of climate change.

Abstract

The oil palm land donated to Universitas Samudra is planned for the development of the campus area, including the construction of a number of buildings and supporting facilities. However, the process of identifying and mapping oil palm plants has been done manually, which is time-consuming, inefficient, and prone to errors. This problem underscores the need for faster and more accurate methods to support spatial data-based planning. This study aimed to calculate the number of oil palm plants in 2022 and 2023 at the University of Samudra using the template matching method with eCognition Developer software, as well as evaluate the accuracy of automatic detection results based on aerial images obtained using drones. The research was carried out using survey methods and descriptive analysis, involving primary data in the form of aerial imagery and field validation, as well as secondary data from the map of the oil palm plantation area of Samudra University. The results of the study show that the number of oil palm plants in 2022 based on automatic calculations was 2,060 trees, while the results of manual validation showed the actual number of 2,169 trees with a difference of 109 trees. In 2023, the automatic calculation detected 1,932 trees, while the actual number was 2,030 trees, with a difference of 98 trees. The accuracy level of automatic calculations in 2022 had an average accuracy of 98.56%, recall of 94.05%, and F1-score of 95.63%, higher than in 2023 with precision of 97.41%, recall of 92.73%, and F1-score of 94.98%. Then the template matching method is effectively used for oil palm tree detection and can support the planning of campus area development efficiently. The use of this technology is expected to be a model that can be implemented in various other educational institutions.

Abstract

One of the impacts of the rampant urbanization is the rising phenomenon of Urban Heat Island (UHI). This phenomenon occurs when the temperature in urban areas is higher than in the surrounding areas that are less developed (rural). The research was conducted in DKJ Jakarta Province, namely East Jakarta City, South Jakarta City, North Jakarta City, Central Jakarta City, and West Jakarta City. This study aimed to analyze the highest and lowest distribution of UHI based on the Land Surface Temperature (LST) algorithm and using the overlay method. Data were collected through literature study and analysis of Landsat 8 level 2 satellite imagery collection 2 Tier 1 OLI 2. The results of the study showed that high urbanization (population density) affected the average value of CSI to increase so that it was directly proportional to UHI. The non-UHI intensity range ranged from -4 oC to 0 oC, while the areas experiencing UHI had an intensity range ranging from ±0oC to 8.6oC. The city with the highest intensity was estimated to be in the East Jakarta City area while the lowest was in the Central Jakarta area.

Abstract

The purpose of this study was to find out and describe the use of GIS in mapping the level of landslide vulnerability in Sibolangit District, Deli Serdang Regency, North Sumatra. The model used referred to the estimation of the 2004 Puslittanak, as it utilizes parameters that are easy to measure, widely available, and in accordance with the territory of Indonesia. These parameters include rainfall, rock type, soil type, slope gradient, and land cover.  The research methods used were overlay, scoring, and weighting. In the mapping process, each parameter had a score of classification multiplied by the weight of each parameter, then the results of the multiplication of the scores and weights were summed based on the suitability of their geographical location. The results of the study showed that the Sibolangit District area had the potential for landslides from low, medium to high levels. Based on the landslide disaster prediction model, the study area predominantly fell under the moderate susceptibility class, covering 15 villages. Additionally, 10 villages were identified with low vulnerability level and 5 villages with high vulnerability level. The use of GIS was also used to see the size of each area in Sibolangit District based on the level of vulnerability to landslide disasters. The level of validity of this map is quite good because it uses official data and methods suitable for the territory of Indonesia. Thus, it is accurate enough for the purpose of vulnerability identification and landslide disaster mitigation planning.
