Abstract

Land use change is the cause of carbon loss from land. The loss of this carbon becomes a source of carbon dioxide (CO2) in the atmosphere that can cause global warming. Intensive land use and land cover occurred in Kabupaten Banyuasin from 2004-2014. The purpose of this study. to create carbon balance, emissions and sequestration of CO2 during the period of 2004 - 2014 in Banyuasin Regency caused by land use change and land cover change. The method used to create carbon balance using land use change matrix, carbon calculation of each carbon pool by allometric method, destructive sample and organic C by Walkley and Black method. Stock diference method for analysis of changes in carbon storage, CO2 emissions and CO2 sequestration. The results of this study indicate that the 2004-2014 carbon balance in Banyuasin Regency is negative, with a carbon loss of 22,033,277 tons with an average annual carbon loss of 2,203,327 tons. CO2 sequestration of 29,298,966 tons and CO2 emissions 118,044,141 tons, while net emissions 88,745,175 tons. Average net CO2 emissions from above ground carbon pools, carbon necromassa pools, litter carbon pools and underground carbon pools are 7 tonnes ha-1 year-1, whereas CO2 emissions from organic soil C 0.61 tonnes ha- 1 year-1. The largest contributor of CO2 emissions in Banyuasin Regency are sequentially caused by changes in peat swamp forests, secondary mangrove forests, primary mangrove forests and secondary swamp forests. While the source of sequestration is the change of monoculture rubber peat, oil palm, rubber monoculture and shrubs.

Abstract

Peat nutrient dynamics research was intended to study the characteristics and distribution of macro nutrients in peat water and peat in secondary forests, shrubs and oil palm plantations. This research was conducted with purposive sampling method. Observations on oil palm plantations were carried out at three ages of oil palm (5, 12, and 16 years). Secondary forest and shrub peatlands were used as a comparison. Sampling of peat water and peat was carried out during the rainy and dry season, at four distances from the collection drain (25, 50, 75, and 150 m). The results showed that nutrient levels in peat water during the dry season were greater than the wet season. The status of peat water and peat nutrients in secondary forests and shrubs is relatively the same as that of oil palm plantations that were fertilized. Seasonal, land use and distance from the collection channel differences did not have a major influence on the distribution and characteristics of macro nutrients on peat. The macro nutrients content of peat water and peat, however, showed an increase with the distance from the collection channel.

Abstract

Rice Field agriculture in Jember district is a main sector due to its contribution to rice production in this region. The objective of this study is to determine the rice field sustainability index based on agro-ecosystem zone and to formulate policy alternatives for supporting the spatial planning in achieving sustainable rice field agriculture. The study used the primary andsecondary data which include biophysical environment, economy, social and culture. The data analysis used GIS (Geographic Information System) modelbase, factor analysis, and AHP (Analytical Hierarchy Process). The results showed that the sustainability index of the rice field agro-ecosystem zones were different. The threats of the rice field sustainability were causedby the main indicators of the biophysical environment, economy, social, and culture such as water availability, soil nutrients of Carbon organic content, Nitrogen, and Phosphor-available, profit, fertilizer access, land conversion, land ownership and fragmentation, farmer education, and age of farmer. To overcome those threats, the policy consideration was more dominantly determined by the biophysical factor rather than that of theeconomy, social, and culture. The implementation of the policy tohandle the threats needs to be coordinated among the stakeholders, considering that the rice field resource can be categorized into a common pool resource.

Abstract

Abstrak. Sifat biofisik lahan berperan penting dalam perencanaan penggunaan lahan maupun perencanaan teknis pengelolaan lahan. Oleh sebab itu identifikasi secara cepat dan akurat sifat biofisik lahan menjadi penting. Citra radar resolusi tinggi sudah banyak digunakan untuk berbagai tujuan, antara lain untuk identifikasi tutupan lahan, analysis geologi dan analisis cuaca. Penelitian bertujuan untuk mengevaluasi penggunaaan citra RADAR resolusi tinggi untuk mengevaluasi sifat-sifat biofisik lahan sawah. Penelitian dilakukan pada areal pesawahan di Kabupaten Indramayu menggunakan citra Radarsat 2 resolusi tinggi (quad polarization) dengan empat polarisasi (HH, HV, VH, VV). Sifat-sifat biofisik lahan yang dianalisis meliputi: salinitas tanah, bobot aktual tanaman, bobot kering tanaman, tinggi tanaman, kekasaran permukaan tanah, dan kelembaban tanah. Data yang dikumpulkan dibedakan atas kelompok lahan sawah yang ditanami padi dan lahan sawah bera. Data yang digunakan terdiri dari 27 set data biofisik lahan sawah yang ditanami padi, dan 49 set data lahan sawah bera. Hasil menunjukkan bahwa dari keenam sifat biofisik lahan yang dianalisis, kelembaban tanah merupakan sifat biofisik lahan yang dideteksi lebih baik dibandingkan sifat-sifat biofisik lahan lainnya, baik dalam kondisi lahan ditanami padi maupun lahan bera. Tetapi model-model persamaan antara sifat-sifat biofisik lahan dan koefisien hamburan balik dari citra Radar resolusi tinggi ini memiliki nilai R2 yang rendah. Hal ini mengindikasikan bahwa pendugaan sifat biofisik lahan dengan nilai koefisien hamburan balik secara langsung tidak dapat digunakan pada lahan sawah.Abstract. The land biophysical properties are important in land use and technical planning in the field. Therefore, rapid and accurate identification of the land biophysical properties is an important step. In the past, the high resolution RADAR images have been used for land cover identification, weather analysis, and geological analysis. This study aims to evaluate the use RADAR images to detect biophysical properties of paddy fields. This research was carried out on paddy fields in Indramayu Regency using high resolution (quad polarization) Radarsat 2 imagery with four polarizations (HH, HV, VH, VV). The analyzed land biophysical properties included soil salinity, actual plant biomass, plant biomass (dry weight), plant height, soil surface roughness and soil moisture. The data were collected from 27 data sets of land planted with rice and 49 data sets from bare lands. The result show that of the six biophysical properties, soil moisture was the biophysical property which was detected better than the others, both on land planted with rice and bare land. But the equation models between biophysical properties and backscattering coefficient had a low R2 value. This indicates that the method to estimate soil biophysical properties using backcsaccter coefficient directly can not be applied for paddy soil.

Abstract

The area of irrigated rice fields during 2017-2018 has decreased by 19.84% in Indonesia and 30.10% in Bogor Regency. Wetland agricultural area of Bogor Regency Spatial Plan (RTRW) is intended for wetland food crops (lowland rice) which are cultivated intensively because their potential to provide an irrigation system thus urge to be protected. In certain conditions, land registration has impact on the conversion of agricultural land. This study aims to examine the relationship between land administration and the conversion of agricultural land. Interpretation of Google Earth imagery and field checks are methods for inventories of constructed land. The relationship between the variable y (built-up area) and the variable x (land administration) is modeled by Geographically Weighted Regression (GWR). Literature study of land administration regulations was carried out to understand the modeling results with the realities that occur in the field. The dynamics of land administration are greatest in the northern part of Central WP Bogor Regency, in the suburbs of South Tangerang City, and Depok City. The modeling produces a global value of R2 0.72 and local R2 0.44 to 0.86, meaning that land administration has the opportunity to become an instrument of control, by tightening the service requirements specified in the Regulation of the Head of the National Land Agency RI No. 1 Tahun 2010.

Abstract

South Tangerang City is experiencing a process of suburbanization, where the increase in population causes an increase in the need for space for development. If development activities are not controlled, it will reduce the quality of the environment and people's lives. Land management is an activity that aims to support development programs by utilizing the capacity of land resources. This study aims to analyze the level of regional development and analyze the influence of land administration in supporting regional development in South Tangerang City in 2016 and 2019. The level of regional development is analyzed weighted scalogram with modification of physical, social and economic variables. The relationship between the Y variable (Urban village development index-IPWK) and the X variable (Land administration) was modeled using Geographically Weighted Regression (GWR). The results of the regional hierarchy analysis show that the urban village in South Tangerang City are dominant in Hierarchy 3 with an average IPWK value result 46.25 (2016) and 45.38 (2019), as a hinterland for DKI Jakarta. Land administration activities can have different positive and negative effects locally on the level of development of the urban village area.

Abstract

Penelitian ini menganalisis kondisi struktur agraria dan sistem penghidupan masyarakat di Desa Sumberklampok pasca-reforma agraria serta implikasinya terhadap kebijakan pembangunan berkelanjutan. Penelitian ini menggunakan pendekatan metode campuran (mixed-method) dengan teknik analisis deskriptif dan indeks skoring berdasarkan lima modal penghidupan: modal manusia, sosial, finansial, alam, dan fisik. Hasil penelitian menunjukkan bahwa reforma agraria telah meningkatkan kepastian hukum atas tanah dengan sertifikasi redistribusi tanah sebanyak 62,71% dari total luas tanah di Kawasan Kampung Reforma Agraria Desa Sumberklampok. Stabilitas sosial juga meningkat melalui penyelesaian konflik agraria, yang berdampak pada restrukturisasi penguasaan lahan antara masyarakat dan Pemerintah Provinsi Bali. Namun, tantangan signifikan masih dihadapi, terutama dalam aspek rendahnya tingkat pendidikan dan keterampilan masyarakat, keterbatasan akses terhadap sumber daya air, serta kesulitan memperoleh permodalan dan akses pasar. Untuk mengatasi kendala tersebut, diperlukan integrasi kebijakan reforma agraria dengan program pembangunan kapasitas masyarakat, investasi infrastruktur berkelanjutan, serta penguatan kelembagaan berbasis komunitas guna menjamin keberlanjutan sosial dan ekonomi. Selain itu, peningkatan akses terhadap kredit inklusif serta diversifikasi ekonomi berbasis potensi lokal yang dilakukan secara partisipatif menjadi faktor kunci dalam mengoptimalkan manfaat jangka panjang reforma agraria. Pendekatan kebijakan yang integratif dan berbasis kebutuhan lokal ini diharapkan dapat memperkuat hasil reforma agraria serta mendorong pembangunan inklusif yang berkelanjutan bagi masyarakat Desa Sumberklampok.

Abstract

Land cover changes resulting from mining activities in Central Bangka District have often led to environmental degradation, significant challenges for local communities, and disruptions to spatial utilization. This study aims to identify land cover change patterns within the tin mining business license (IUP) area from 2014 to 2022 and evaluate their impacts on ecosystems and land use. The study employed the Maximum Likelihood Classification (MLC) method for satellite image analysis to detect land cover changes. The results indicated that mining land expanded by 2,117.29 ha between 2018 and 2022, primarily due to the conversion of secondary and natural vegetation. Meanwhile, secondary vegetation declined significantly, with 4,187.46 ha reduction from 2014 to 2022, highlighting the extensive exploitation of land for mining activities. Additionally, an increase in water bodies was observed due to the formation of water-filled mine voids, locally known as "kolong". The classification accuracy assessment demonstrated high reliability, with Kappa coefficients of 93.7% in 2014, 92.73% in 2018, and 94.5% in 2022, confirming the effectiveness of the MLC method in detecting land cover changes. The findings of this study provide critical insights for post-mining land management, emphasizing the need for enhanced reclamation and revegetation strategies. A more comprehensive understanding of land change dynamics is expected to support sustainable spatial planning and inform environmental impact mitigation policies in Central Bangka District.

Abstract

Studies have shown that coal fly ash (CFA) can improve soil physical properties (such as bulk density) and increase available water content. However, its pozzolanic properties may also contribute to soil compaction. The overall impact of these contrasting effects on soil behavior remains insufficiently understood. This study investigated the effects of CFA amendment on soil resistance, water retention, and corn root growth in sandy soil. Using a completely randomized design, the research was conducted at the Taman Bogo Agricultural Station in East Lampung for two planting seasons (October 2022 - June 2023). Four CFA rates (0%, 3%, 6%, and 12% w/w) were applied in lysimeter plots with five replications. The results demonstrated that CFA application reduced soil bulk density (BD) at 6% and 12% rates due to CFA’s lower BD than the soil. However, higher CFA doses increased soil penetration resistance (PR), likely due to surface crust formation rather than pozzolanic reactions. Plant available water capacity (PAWC) significantly increased by 6% and 12% CFA, thus improving soil water retention. Improving physical properties in the second season promoted root growth at the 12% CFA rate. The use of CFA in sandy soils leads to improvement in selected physical properties and enhances water retention. Therefore, while CFA enhances water retention, its effects on soil compaction and root growth must be carefully managed to ensure optimal results.
