The purpose of this study was to analyze the relationship between bird and tree diversity. Data was collected using plot and point count methods, then analyzed descriptively quantitatively using diversity index, significant value index and correlation analysis. The results showed that the index value of bird and tree diversity was classified into the medium category, namely H'=2.06 and H'=1.02. Correlation analysis shows that there is no significant relationship between the two variables. The absence of a relationship between the two variables occurs due to the lack of availability of bird feed on agroforestry land so that the birds only use trees to play, stop or perch. A more diverse variety of plants can increase bird diversity, but in this study this was not found. Based on the research results, it is hoped that the government and the community will increase bird diversity t...

This research was conducted to determine the role of variables of demographic, asset ownership, and encroached land accessibility on the ancroacher's acceptance. It carried out at KPH Selagai Lingga Register 39 Central Lampung Regency. Semistructured interviews were conducted on 96 randomly selected squatters. The Ordinal Loglinear Postulate Model is applied at an accuracy rate of 95%. The response variables were scored 1, 2, 3, and 4 which indicated the responses were disagree, hesitate, agree and strongly agree. There are 13 predictor variables: age (years), number of dependents (live), education (junior high school graduation versus not), income (Rp million/year), type of crop (coffee versus others), side business (have versus not), residence (inside versus outside the area), ethnicity (Javanese versus others), area of cultivation (ha), HP ownership (owned versus not), motorized vehicle (owned versus not), distance of land to nearest settlement and main access to land. Optimization parameters using Minitab 16. The results of this study indicate that the level of agreement: [a] will increase significantly if, (i) the age of 1 year is 1.07 times older than the original; (ii) revenue of IDR 1 million to be 1.09 times higher; (iii) living in the area 6.94 higher than outside the area; and (iv) having HP becomes 4.91 times compared to those who don't and significantly reduced if the number of dependents is more than 1 person, which is only 0.32 times the original.

So, ensuring the sustainability of existing mangroves is the need of the hour. In view of above, this study aims to analyze the sustainability index of mangrove ecosystem management and the sustainability status of the mangrove ecosystem from the ecological, economic, social, and institutional dimensions using the Multidimensional Scaling (MDS) method through the Rapid Appraisal for Fisheries (RAPFISH) approach in East Rawajitu Sub-district, Tulang Bawang District, Lampung Province, Indonesia. The analysis revealed that mangrove ecosystem management's sustainability index was categorized as 'less sustainable' (index 43.01 out of 100). Meanwhile, the social dimension (51.65) was categorized as 'quite sustainable', and other dimensions (ecological, economic, and institutional) were 'less sustainable.' Therefore, it is proposed that further development of the social dimension is a strategic way to develop the other three sustainability dimensions to achieve ecosystem sustainability as a whole in the study area. Alternati ve strategies that can be applied for sustainable management of mangrove ecosystems in East Rawajitu Sub-district, Tulang Bawang District are increasing coordination between stakeholders, creating formal regulations, increasing the productivity and creativity of Ikatan Istri-istri Petambak Dipasena (ISTANA), formulating an integrated mangrove ecosystem management plan program, undertaking rehabilitation efforts, increasing the role of mangrove groups, and increase the attention of researchers.

Indonesia is a country with a high burden of the disease and is ranked second as a contributor to tuberculosis in the world after India, China, the Philippines, and Pakistan [1] along with the phenomenon of deforestation [2] and global warming [3]. Forest restoration and reforestation are considered costeffective nature-based solutions for climate change adaptation and mitigation to remove carbon dioxide from the atmosphere, provide habitat for species and balance temperatures. Methods: There is no research data on the contribution of the economic value of reforestation to reduce the incidence rate of infectious diseases especially for TB, which is very important for mitigating against the global warming. This research was conducted to determine the economic value of ecosystem services as compensation for the reforestation program. This research was carried out in Lampung

However, its quality deteriorates continuously due to land use change accompanied by housing expansion and open areas. This study aims at analyzing its water quality and pollution level based on the present land-use zoning. Three zones are determined based on the dominant land use covering the riverbank sides. Water sampling was carried out at nine settling points (3 samples per zone) to measure the level of BOD 5 , COD, TSS, Escherichia coli contends, and also Pollution Index (PI), as well as the Biodegradable Index (BI). The results showed that the water has been experiencing pollution for grade-C river overall data. However, based on the zoning, all of the parameters of the upstream sides are below quality standard (QS), while at the middle stream, the BOD 5 has exceeded QS (21.9-26.4 mg/L), whereas at the downstream, the parameters of BOD 5 , COD, and Escherichia coli have exceeded from the QS. The PI and BI values indicated moderately polluted downstream, with the average biodegradable. For this reason, paying attention to land use change is important to assess the level of river pollution. The study results also found that organic matter from domestic is the primary pollutant of the river. Therefore controlling the upstream in accordance with regional spatial planning regulations and followed by a conservation movement as well as change people's behavior to be more caring about environmental management for catchment areas are the urgent actions for restoring and improving the river water quality.

Penelitian ini bertujuan untuk mengetahui bentuk kelembagaan yang berjalan terkait dengan aktivitas PETI batubara. Penelitian ini menggunakan pendekatan kualitatif yang menggambarkan bagaimana PETI tetap beroperasi meskipun ilegal. Hasil penelitian menunjukkan bahwa kelembagaan formal yang ada tidak berjalan dengan baik sehingga tercipta kelembagaan non formal yang memungkinkan PETI bisa berjalan. Beberapa persyaratan teknis yang dimuat dalam peraturan perundang-undangan tidak dapat dipenuhi oleh PETI jika dilegalkan menjadi pertambangan rakyat. Koordinasi dan kerjasama yang baik antara pemerintah termasuk aparat penegak hukum dengan perusahaan pertambangan sangat diharapkan untuk mengendalikan perkembangan PETI serta dampak yang ditimbulkan, khususnya di hutan rakyat. Kata kunci : hutan rakyat, kelembagaan, kerusakan lingkungan, pertambangan tanpa izin, tambang batubara ABSTRACT Unlicensed Mining (PETI) conducted by community groups in private forest area is rife in Muara Enim district which causing environmental degradation. The purpose of this study is to find out the institutional forms associated with illegal coal mining activities. The study used a qualitative approach that illustrated how unlicensed mining (PETI) still able to operate despite violating the law. The result of this study indicates the existing formal institutions did not run so well which lead to the creation of non-formal institutions who permits illegal activities. There are few technical requirements that PETI could not provide if they were legalized to be public mining. Good coordination and teamwork between government and law enforcers along with mining corporation are desirable to control the development of PETI and the impact it brings, especially in private forest.

Considering this, the present study aimed to assess the mangrove cover and density change in mangrove forest of Tulang Bawang District, Lampung Province, Indonesia. Data was collected by remote sensing techniques using satellite imagery viz., Landsat 5 in 2000 and 2010 and Landsat 8 in 2020. It was then analyzed using remote sensing method, namely Object-Based Image Analysis techniques using the unguided classification method to obtain mangrove cover data; while mangrove density information was obtained using the Normalized Difference Vegetation Index algorithm. The results revealed the decrease in mangrove cover and density between 2000 and 2020. The mangrove cover decreased from 7529 ha in 2000 to 5551 ha in 2020. Furthermore, density of mangrove forest has also witnessed change from dense density class in 2000 to medium density class in 2020. From this result, it is evident that mangroves of East Rawajitu Sub-district are degrading and require focused efforts to prevent the degradation. Communities, entrepreneurs, and governments have different motives for utilizing mangrove forests that result in damage, so reasonable efforts are needed to manage mangrove forests sustainably.

Economic growth in both national and local level is closely related to the performance of the productions of goods and services, which measured by massive increase in the amount of the Gross Domestic Product (GDP) and Regional Gross Domestic Product (RGDP) for the region. Lampung province's economic growth performance is high enough but on the other hand had to be paid by land conversion. This study aims to determine changes in forest cover and land as well as its influence on the RGDP in agriculture, forestry and industry. Data collected consist of satelitte image of lampung province RGDP in agricultural sector, RGDP in foresty sector, RGDP in industrial sector and population density data. The research method is to perform modeling of multiple linear regression Ummi Dienelly using Minitab version 16, with the response variable Y 1 is the RGDP in the agricultural sector, Y 2 is RGDP in the forestry sector, Y 3 is RGDP in the industrial sector and the explanatory variables (X) used include the proportion of forest area of the country , privat forests, agricultural land, rice fields, and undeveloped land, plantations, other areas, and the data density of population per km 2. The result showed that there was a significant relationship beetwen changes in private forest cover by 11.055 (p= 0.062), rice field by 7.982 (p= 0.082), and population density by-8.676 (p= 0.000) to the RGDP in agricultural sector. RGDP in the forestry sector is affected significantly by the national forest cover by 1.160 (p= 0.00) and other land use by-0.803 (p= 0.061). RGDP in the industrial sector is influenced significantly by private forest-7.434 (p= 0.077), and plantation by 5.471 (p= 0.00).

Considering this, the present study aimed to assess the mangrove cover and density change in mangrove forest of Tulang Bawang District, Lampung Province, Indonesia. Data was collected by remote sensing techniques using satellite imagery viz., Landsat 5 in 2000 and 2010 and Landsat 8 in 2020. It was then analyzed using remote sensing method, namely Object-Based Image Analysis techniques using the unguided classification method to obtain mangrove cover data; while mangrove density information was obtained using the Normalized Difference Vegetation Index algorithm. The results revealed the decrease in mangrove cover and density between 2000 and 2020. The mangrove cover decreased from 7529 ha in 2000 to 5551 ha in 2020. Furthermore, density of mangrove forest has also witnessed change from dense density class in 2000 to medium density class in 2020. From this result, it is evident that mangroves of East Rawajitu Sub-district are degrading and require focused efforts to prevent the degradation. Communities, entrepreneurs, and governments have different motives for utilizing mangrove forests that result in damage, so reasonable efforts are needed to manage mangrove forests sustainably.

Economic growth in both national and local level is closely related to the performance of the productions of goods and services, which measured by massive increase in the amount of the Gross Domestic Product (GDP) and Regional Gross Domestic Product (RGDP) for the region. Lampung province's economic growth performance is high enough but on the other hand had to be paid by land conversion. This study aims to determine changes in forest cover and land as well as its influence on the RGDP in agriculture, forestry and industry. Data collected consist of satelitte image of lampung province RGDP in agricultural sector, RGDP in foresty sector, RGDP in industrial sector and population density data. The research method is to perform modeling of multiple linear regression Ummi Dienelly using Minitab version 16, with the response variable Y 1 is the RGDP in the agricultural sector, Y 2 is RGDP in the forestry sector, Y 3 is RGDP in the industrial sector and the explanatory variables (X) used include the proportion of forest area of the country , privat forests, agricultural land, rice fields, and undeveloped land, plantations, other areas, and the data density of population per km 2. The result showed that there was a significant relationship beetwen changes in private forest cover by 11.055 (p= 0.062), rice field by 7.982 (p= 0.082), and population density by-8.676 (p= 0.000) to the RGDP in agricultural sector. RGDP in the forestry sector is affected significantly by the national forest cover by 1.160 (p= 0.00) and other land use by-0.803 (p= 0.061). RGDP in the industrial sector is influenced significantly by private forest-7.434 (p= 0.077), and plantation by 5.471 (p= 0.00).
