Abstract

Conversion of natural forest into plantation forest at Gunung Ciremai which managed by Perum Perhutani for three decades, gaves significant destructive impacts to sulrili’s habitat and triggering surili to disperse to the more secure habitat.  After the change of forest function to conservation forest in 2004, preference habitat surili is unknowing. Therefore, the initial step of the conservation efforts to restore population were by analyzing the habitat preferences surili. Chi-square analysis and Neu analysis was used to analyze the habitat preferences surili. Research carried out from September to November 2016 in Gunung Ciremai National Park. Preferential habitats characteristic of surili on Gunung Ciremai National Park are such as elevation from 1.500 to 2.400 m above sea level, densely forest stand >50%, distance to the edge of the forest (0-665meter), distance to the settlement (0-806 meters), distance to the hiking trail (0- 1572 meters), surface temperature 16,3-18,5°C, steep slope (25-40%), preference for habitats that is secondary forest cover. Keywords: Gunung Ciremai  National Park, preferential habitat, surili

Abstract

Pertambangan batubara berperan penting dalam pertumbuhan perekonomian Indonesia, meskipun aktivitas tersebut berdampak negatif bagi lingkungan. Meminimalisir hal tersebut, pemerintah Indonesia mewajibkan reklamasi di lahan bekas tambang dengan salah satu indikator nya adalah keberhasilan tutupan tajuk. Saat ini belum ada metode terukur yang dapat menentukan tingkat keberhasilan tutupan tajuk pada lahan reklamasi. Penelitian ini dilakukan untuk mengembangkan metode pengukuran berbasis data remote sensing dengan pendekatan Forest Canopy Density (FCD) yang dilakukan di wilayah izin pertambangan PT. Multi Harapan Utama, Kutai Kertanegara. Pemodelan FCD dilakukan dengan mengintegrasikan 4 indeks biofisik dari pengolahan citra Landsat 8 OLI TIRS selama 2013–2021. Hubungan antara nilai FCD terhadap tutupan tajuk di lapangan menggunakan regresi linier untuk memperoleh nilai keberhasilan tutupan tajuk berdasarkan nilai FCD. Hasil pemodelan FCD menunjukan tren kenaikan setiap tahunnya, khususnya pada 2 tahun pertama setelah penanaman. Analisis regresi menunjukan hubungan kuat antara nilai FCD dengan nilai tutupan tajuk dengan R2=0,775 dan mendapatkan nilai FCD 75,35 merupakan batas keberhasilan tutupan tajuk di lahan reklamasi. Penelitian ini menunjukkan bahwa pendekatan FCD dapat diterapkan untuk menentukan tingkat keberhasilan reklamasi lahan bekas tambang

Abstract

Rhinoceros hornbills (Buceros rhinoceros) are a bird species belonging to the Bucerotidae family, which is vulnerable based on the IUCN red list of species. This is due to habitat fragmentation, which reduced the Rhinoceros hornbill habitat on Java. Efforts and strategies are needed to maintain Rhinoceros hornbill habitats. Information on the suitability of the Rhinoceros hornbill habitat on Java Island is required to develop a Rhinoceros hornbill conservation strategy. This study aimed to determine a habitat suitability model that produces the highest accuracy, analyze hornbill habitat suitability, and identify environmental variables that affect the existence of rhinoceros hornbills. Habitat suitability models were processed using three algorithms: random forest, support vector regression, and MaxEnt. The data used to model habitat suitability were presence and environmental variables. The model was evaluated using various accuracy measures, namely overall accuracy, sensitivity (sn), specificity (sp), Area Under Curve (AUC), and kappa coefficient. The resultsof model processing showed that the random forest algorithm produced the highest average accuracy of 0.74. The most important environmental variables for the habitat suitability model were the distance from the road (16.62%), distance from the forest (12.73%), and land cover (12.47%). The habitat suitability model was divided into three classes: low suitability, covering 75,048 km2 (55.94%); medium suitability, covering 52,911 km2 (39.44%); and high suitability, covering 6,213 km2 (4.63%). The results of the habitat suitability model showed that the habitat suitability class was the smallest in the area.

Abstract

Indonesia is one of the largest countries globally with an area for planting sugarcane. The current problem is that determining the planting area of sugarcane is still done conventionally; this is very limited and wastes time. Thus, knowing the sugarcane planting area becomes essential for policymaking through Remote Sensing technology. However, the challenge of Remote Sensing is the limited data due to weather and the spectral variability of other plants. So, it is necessary to classify based on phenological knowledge. The study aims to classify sugarcane areas based on phenological knowledge using Remote Sensing and Machine Learning. This application finished on the cloud platform Google Earth Engine (GEE) through Landsat 8 satellite imagery data. The knowledge of sugarcane phenology was built based on the Normalized Difference Vegetation Index (NDVI) spectral value and built with the harmonic model. In addition, classification is accomplished by object-oriented (OO) methods for segmentation classification. Object-oriented is solved by the Simple Non-Iterative Clustering (SNIC) algorithm for spatial cluster identification, the Gray-Level Co-occurrence Matrix (GLCM) for texture extraction, and the Random Forest algorithm for Land Use-Land Cover (LULC) classification. The results of the accuracy analysis using the confusion matrix and the classification of sugar cane areas based on phenological knowledge obtained the best results with an overall accuracy of 95.9% with a Kappa coefficient of 0.92. It can be concluded that a classification approach with knowledge of plant phenology can help better classify the availability of land for plantations in the future.

Abstract

Improving rice productivity and efficiency is the main goal of cultivation techniques to meet the demand for rice production. The aim of this research was to evaluate the suitability of rice varieties in cultivation systems, namely: organic cultivation + biological pest management (BPM), inorganic cultivation + BPM, and conventional cultivation. Different types of rice varieties, namely New Superior Varieties (NSV: INPARI-30, INPARI-32), New Plant Type (NPT: IPB-3S), and Superior Varieties from West Sumatra (Batang Piaman, Anak Daro), may exhibit differences in agronomic performance across various cultivation systems. This research was conducted at the Sawah Baru Babakan Experimental Farm, IPB University, Dramaga Bogor, using a factorial nested design with 4 replications. The results based on yield per hill and plot showed that Batang Piaman and INPARI-30 varieties were suitable for all organic + BPM, inorganic + BPM, and conventional cultivational systems. The INPARI-32 and IPB-3S varieties were more suitable for conventional cultivation and inorganic + BPM; while the Anak Daro variety was better in organic cultivation + BPM. Utilizing varieties with different characteristics for better yield performance could be considered with obtaining the suitability of the cultivation system, whether organic + BPM, inorganic + BPM, or conventional. Keywords: Chemical pest control; conventional cultivation; organic cultivation; integrated pest management

Abstract

Bali starling (Leucopsar rothschildi) is categorized as an endangered species based on IUCN, Appendix I based on CITES, and protected animals by the goverment of Indonesia. Bali Barat National Park (BBNP) has a breeding center for the recovery of species population in their natural habitat. The BBNP promoted soft release method for the introducing species in the wild habitat. This method consists of some treatments for supporting bali starling life and as consequently the distribution of species was concentrated in small area and the species can be monitored easily. This method has an effect the natural behaviour of bali starling is difficult to be formed and makes dependence on humans, and an effect on the shift of habitat choise by bali starling in BBNP. The problem is when the bali starling has been released to the wild. The number of individuals who have been released shows decrease fluctuation. This study was aimed to analyze potential of natural habitat. This study method using a vegetation analysis. The result found that the potential habitat with an importance value index is kemloko in the pole classification with a value 230.37% in the savanna ecosystem and talok with a value 86.27% in the monsoon forest ecosystem. The potential habitat in BBNP can still support the survival of bali straling.

Abstract

Open mining activities result in decreased microbial biomass and negatively impact soil fertility. Soil microbes play a key role in the decomposition of soil organic matter and in nutrient cycling through mineralization mediated by the enzymes they produce. The purpose of this study was to analyze soil fertility levels at PT Bukit Asam’s various reclaimed land sites in Muara Enim Regency, South Sumatra, Indonesia, as determined by microbial populations and soil enzyme activity. The research was conducted using an explorative method across PT Bukit Asam’s reclaimed land sites. Soil samples from seven reclamation areas of different ages were analyzed. Our results showed that soil conditions and enzyme activity vary with reclamation age. At KTU, a 12-year-old reclaimed site, urease enzyme activity was 68.83 mg NH₄⁺·g⁻¹ dm·h⁻¹, with a microbial population of 82.64 × 10⁴ CFU·g⁻¹ soil. The highest phosphatase activity, 95.66 mg pNP·g⁻¹ dm·h⁻¹, was observed at the 9-year-old SP702 reclaimed site, with a soil pH of 5.23. Cellulase activity at the 21-year-old Udongan site was 21.51 mg GE·g⁻¹ dm·h⁻¹, with a cellulolytic microbial population of 1.9 × 10⁴ CFU·g⁻¹ soil, higher than at other reclamation sites. Invertase activity at the 15-year-old Tupak site was 24.37 mg GE·g⁻¹ dm·h⁻¹. Soil enzyme activity can serve as an indicator of soil quality and microbial activity, reflecting biochemical transformations in the soil and exhibiting high sensitivity to environmental changes.

Abstract. Remote sensing is composed of many interrelated processes to be able to consider physical objects such as buildings, land, and plants which are objects that can be discussed by applications discussed in various disciplines that discuss geology, forestry, soil science, and geography. The use of GIS and remote sensing for fire monitoring has been widely used. However, this study is the first study conducted in the TNBS area after the Berbak National Park (TNB) in Jambi to join the Sembilang National Park (TNS) in South Sumatra. Hotspot distribution in this study was obtained using Getis-Ord-Gi * statistics, hotspot data collected from 2000-2018 in the TNBS area. The results of the hotspot distribution during the 2000-2018 recorded by MODIS satellites with time acquisition and statistical analysis using Gi* show the results that the hotspots gathered (80% confidence level) outside the TNBS area, which is a mixed fields area. Further studies on causes of fire in terms of socio-economic and cultural needs to be done to get the right advice in reducing the risk of loss of forest cover and diversity in TNBS.
