Abstract

Mangrove degradation in Bandar Lampung, specifically Kota Karang, Teluk Betung Timur, has left only 9,86% or 6 hectares, causing habitat loss and increased greenhouse gas emissions. This study identifies deficiencies in the government-led mangrove management system, emphasizing individual management leading to overlapping responsibilities and a lack of coordination. The research method employed is descriptive qualitative, incorporating primary data from observations, interviews, and documentation, alongside secondary data and literature studies. Observations encompass the assessment of biophysical elements, ecological indicators, and mangrove reduction due to land conversion. Literature studies focus on identifying soil types, water pH, dissolved oxygen levels, mangrove vegetation types, and principles of integrated landscape management. SWOT (Strength, Weakness, Opportunity, Threats) analysis considers stakeholders roles, disaster risks, land conversion, pollution, over-exploitation, and community participation. Findings prompt five strategies: community empowerment, eco-friendly tourism, cross-sector cooperation, enhanced monitoring, and mangrove rehabilitation. Recommendations, rooted in integrated landscape management, target all stakeholders, with a focus on government involvement. This holistic approach addresses identified issues, striving for enhanced mangrove ecosystem sustainability through collaborative efforts and strategic planning, emphasizing the need for coordinated stakeholders action in mangrove conservation. Keywords:  degradation, land conversion, stakeholders, SWOT analysis.

Abstract

Background: Pekon Biha Pesisir Barat is one of the villages directly adjacent to a body of sea water. This is a concern if it is not balanced with supporting information about the importance of mangrove habitat for rehabilitation. There is very little understanding of mangroves in this area. It can be seen from the people who carry out large-scale land conversion. This PKM aims to introduce the benefits of mangroves in a module with the BIOMA (Basic Information of Mangrove) concept as an effort to prevent disaster risk at SDN 1 Biha, Pekon Biha, Pesisir Barat Lampung. Methods: BIOMA is arranged based on tiered material that stimulates the sense of sight. The Village Partner is Pekon Biha, West Coast of Lampung. The method is carried out by teaching mangrove modules and interactive videos and evaluation through pre and post-test. Result: BIOMA mangrove education media received very high attention from elementary students, there was an increase in knowledge of 36% (very good). The pre-test showed that knowledge about mangroves in the good category was only 13%, after the provision of educational media, there were 76% of students who had very good knowledge about mangroves. The novelty of this PKM is creating interactive modules with live demonstrations with storylines that are close to the community. Conclusion: This media is effective in providing information related to mangroves.

Abstract

Pantai Pasir Putih di Lampung membutuhkan evaluasi terhadap nilai keindahan lanskap untuk melihat preferensi pengunjung wisata. Hal ini dapat menjadi masukan penting dalam pengelolaan dan pengembangan lanskap objek wisata. Dalam suatu perjalanan ke objek wisata, pengunjung memerlukan kepuasan secara psikologis terhadap lanskap pesisir yang dijadikan objek wisata. Preferensi masyarakat terhadap wisata pantai pesisir dapat bervariasi berdasarkan faktor-faktor yang melibatkan kebutuhan dan minat pengunjung, salah satunya adalah karakter visual lanskap. Metode Scenic Beauty Estimation (SBE) dapat digunakan untuk menilai secara kuantitatif preferensi masyarakat terhadap suatu lanskap. Berdasarkan analisis yang dilakukan terhadap hasil kuesioner tentang lima foto lanskap, SBE menunjukkan bahwa foto lanskap gerbang masuk memiliki nilai tertinggi (24,08; Tinggi). Sementara empat lanskap lain memiliki nilai sedang dan rendah. Lanskap dengan nilai rendah dapat dijadikan prioritas rekomendasi desain melalui preseden yang dipilih agar nilai estetika dapat meningkat. Hasil dari penelitian ini diharapkan dapat memberikan dampak peningkatan ketertarikan pengunjung untuk melakukan perjalanan wisata ke Pasir Putih.

Abstract

Urban parks serve as areas that support social interaction and enhance the quality of life for the community. These parks feature vegetation that enhances their aesthetic and provides ecological benefits. Vegetation contributes to visitor comfort and improves park accessibility. However, suboptimal vegetation planning can hinger accessibility for certain groups, such as disabilities, elderly, and children. This study aims to analyze the role and impact of vegetation on accessibility in Vatulemo Park. The research begins with observations, spatial analysis using GIS to examine the distribution of vegetation and circulation patterns park. Additionally, a landscape design evaluation is conducted based on Universal Design principles and accessibility standards for green open spaces. The findings indicate that the distribution of vegetation in Vatulemo Park does not fully support accessibility. Shaded areas along circulation paths and jogging tracks are still insufficient, making the park less comfortable for visitors, especially between 10:00 AM and 4:00 PM WITA. Moreover, the lack of vegetation around seating areas and gathering spaces reduces the park's ecological function and user comfort. Therefore, recommendations for improving vegetation placement within the park are necessary to increase greenery along circulation paths and jogging tracks. The selection of plant species should also be adjusted to avoid obstructing visitor activities and comfort. Furthermore, chosen vegetation should not hinder accessibility, and user-friendly pathways should be provided for individuals with special needs. By implementing these strategies, Vatulemo Park is expected to become a more inclusive, comfortable, and ecologically sustainable public space for the residents of Palu City.

Abstract

Rapid population growth in Bandar Lampung, especially in coastal areas, has impacted the environment. Pasaran Island is a small inhabited island that originally only had an area of 2 ha but has now grown to 12.02 ha due to sedimentation and reclamation carried out by the island's residents. Pasaran Island faces great challenges, especially related to carrying capacity and capacity to maintain environmental sustainability and the quality of life of its residents. This study aimed to analyze the carrying capacity and capacity of Pasaran Island. A spatial analysis approach was used to evaluate land requirements and the limits of the island's ability to support its population optimally. Spatial calculations used were according to the Regulation of the Minister of Public Works No.20/PRT/M/2007 on techniques for analyzing physical, environmental, economic, and socio-cultural aspects in preparing spatial plans. The results showed that the carrying capacity on the Pasaran Island is 0.601, which means that the carrying capacity of the settlement is low and unable to accommodate the population in the area. Based on the analysis of the carrying capacity of people, when viewed specifically on Pasaran Island, it can only accommodate 827 people, even though there are currently 1,500 residents. Thus, the results show that there is an overpopulation of 673 people.

Abstract

One of the concentration processes in processing sulfide gold ore is the flotation technique which takes advantage of differences in mineral surface properties by adding chemical reagents. The addition of chemical reagents to the flotation process can cause environmental problems. Therefore, efforts are needed to replace chemical reagents with more environmentally friendly materials. In this research, an attempt was made to replace chemical reagents with a commonly found plant extract, namely aloe vera, as a bioreagent. Bioflotation experiments on a laboratory scale were carried out using a Denver flotation cell with an aloe vera reagent as a frother. This gold mineral bioflotation experiment was carried out on a 150 mesh size fraction. The results of increasing concentrate levels by flotation indicate that the aloe vera reagent as a frother is able to produce biosurfactants which replace chemical reagents as a more environmentally friendly biofrother and biocollector. This can be concluded based on flotation experiment data with bioreagent which has been tested showing an Au content value of 10.09 and a recovery of 96.15%, while flotation using chemical reagents shows an Au content value of 10.50 and a recovery of 95.96%. So the use of aloe vera as an environmentally friendly bioreagent in the flotation process releasing low sulfidation gold is more effective than the use of chemical reagents because it is indicated that there is a biosurfactant content in aloe vera.
