Abstract

Pengelolaan sumberdaya alam dalam kawasan taman nasional tidak hanya cukup menyandarkan pada pendekatan teknis, tetapi bagaimana merumuskan dan menyusun kebijakan yang lebih terpadu (komprehensif), interdisiplin, dan berbasiskan kemampuan sumberdaya lokal dengan melibatkan semua stakeholder yang berkepentingan atas sumberdaya alam tersebut. Penelitian ini bertujuan untuk mendapatkan data dan penjelasan peluang diakomodasinya kepentingan masyarakat untuk meremajakan tanaman kemiri dalam kawasan Taman Nasional Bantimurung Bulusaraung (TN Babul) sesuai dengan peraturan yang berlaku. Penelitian ini dilaksanakan di Kabupaten Maros pada Kawasan TN Babul, Provinsi Sulawesi Selatan. Pengumpulan data dilakukan melalui studi dokumentasi dan wawancara kepada sejumlah informan kunci. Data dianalisis dengan teknik analisis isi (content analysis ) dan analisis deskriptif kualitatif. Hasil penelitian menunjukkan bahwa keinginan masyarakat untuk meremajakan tanaman kemiri dalam kawasan TN Babul sulit diakomodasi. Hal ini disebabkan oleh ketidak-konsistenan diantara kebijakan pemerintah yang ada (UU No. 5/1990, PP No. 28/2011 dan Permenhut No. P.56/2006). Untuk itu diperlukan revisi-revisi sehingga dapat diimplementasikan pada berbagai kondisi yang berbeda-beda.

Abstract

Sungai Kapuran merupakan salah satu sungai di Kabupaten Pacitan yang memiliki hulu berupa hutan seluas 96,62 Ha. Sepanjang sempadan Sungai Kapuran terdapat berbagai penggunaan lahan, salah satunya adalah sebagai industri tambang tembaga. Keberadaan industri tambang tembaga ini disinyalir turut berperan dalam penurunan kualitas perairan di Sungai Kapuran. Hal ini disebabkan karena industri ini membuang hasil limbah tambangnya langsung ke badan Sungai Kapuran, meskipun industri ini sudah tidak beroperasi lagi. Penelitian ini bertujuan untuk mengetahui perbedaan kualitas fisis dan kemis perairan dan indeks pencemaran pada bagian hulu, tengah dan hilir Sungai Kapuran. Pengambilan sampel pada penelitian ini dilakukan secara sistematik. Terdapat empat titik pengambilan data dalam satu lokasi pengamatan dengan jarak antar titik 100 meter. Data variabel kualitas fisis perairan yang diambil meliputi suhu, kecerahan, kecepatan arus, dan TSS, sedangkan variabel kemis meliputi pH, DO, BOD, COD, dan kadar tembaga. Hasil analisis menggunakan Kruskal Wallis menunjukkan bahwa bagian hulu, tengah dan hilir Sungai Kapuran memiliki perbedaan signifikan pada variabel kualitas perairan, yaitu suhu, pH, TSS, dan kadar tembaga, sedangkan untuk variabel kecerahan, kecepatan arus, DO, COD, dan BOD tidak memiliki perbedaan signifikan. Hasil perhitungan indeks pencemaran menggunakan metode Indeks Pencemaran (PIj) menunjukkan bahwa bagian hulu, tengah dan hilir Sungai Kapuran masuk ke dalam kategori tercemar ringan dengan kisaran PIj 1,47-2,29.Kata kunci : Kualitas perairan, tambang tembaga, Indeks Pencemaran

Abstract

Penyebab gagalnya rehabilitasi mangrove di Pantai Utara Jawa Tengah adalah faktor habitat. Oleh karena itu perlu kajian yang lebih mendalam terhadap habitat mangrove, antara lain upaya menyederhanakan komponen habitat yang rumit dengan cara membuat klasifikasi. Klasifikasi habitat mendasarkan pada delineasi tiga peta, yaitu peta kemiringan pantai, ketebalan Lumpur dan salinitas. Peta-peta tersebut difokuskan pada tiga tahun tanam (1997, 1999 dan 2000). Delineasi peta menghasilkan 32 unit ekologis. Tiap-tiap unit ekologis diukur kerapatan dan tinggi vegetasi, kepadatan plankton, hara pada lumpur dan oksigen terlarut. Klasifikasi menggunakan analisis tandan dengan koefisien jarak Mean Euclidean Distance (MED). Hasil penelitian menunjukkan bahwa klasifikasi 32 unit ekologis menghasilkan 4 kelompok habitat berdasarkan komponen habitat yang dikaji. Pertama, pada jarak tandan 15 terdapat 2 kelompok besar, yaitu A (ada 13 unit ekologis) dan B (ada 19 unit ekologis). Kedua, pada jarak 10 kelompok A terbagi menjadi terdapat 2 kelompok, yaitu C (ada 15 unit ekologis) dan D (ada 4 unit ekologis). Ketiga, pada jarak 5, kelompok B terbagi menjadi 2, yaitu E (ada 6 unit ekologis) dan F (ada 7 unit ekologis). Keempat, pada jarak 4, kelompok C terbagi menjadi 2 kelompok, yaitu G (ada 7 unit ekologis) dan H (ada 8 unit ekologis). Kelompok yang paling baik sebagai habitat mangrove adalah kelompok D yang meliputi daerah Pantai Utara Brebes dan Kendal. Secara umum faktor pembeda terbentuknya klas-klas tersebut adalah plankton. Pola pengelompokan ini dapat dijadikan acuan dalam menentukan lokasi yang baik untuk p enanaman khususnya di Pantai Utara Jawa Tengah.

Abstract

Surakarta City's population is growing every year, putting pressure on the land and vegetation. Surakarta City has a population of 500,173 people in 2010. The population of this city is growing every year, driving an increase in the demand for land and living facilities. This study aims to analyze the availability of vegetated land as urban green space, and calculate the 5-year (2010–2015) vegetation cover changes. The methods used visual interpretation and on-screen digitization of the image Landsat 7 ETM+ satellite in 2010 and Landsat 8 OLI satellite image in 2015. The results show that the availability of vegetated land as urban green space in Surakarta City is lower than that mandated in Law Number 26 of 2007 concerning Spatial Planning. Vegetation cover decreased from 2010 to 2015 in Surakarta City, covering an area of 117.7 ha (2.6% of the city area) or an average of 23.5 ha (0.5%) per year. Research on the availability of green open spaces on a regular basis is expected to be part of the process of monitoring and evaluating urban development and as input for local governments in the decision-making process.

Abstract

Social capital has an important role in mangrove management on conservation areas. Utilization of mangrove forest with silvofishery system can be an alternative developed for the community around the conservation areas. The purpose of this research is to know the strength of social capital in supporting the utilization of mangrove for silvofishery. This research adopted Social Capital Assessment Tool method and data analysis with Partial Least Square-Structural Equation Modeling. The results of the study found that there were several elements of social capital in five study villages that have not supported silvofishery in Kutai National Park (KNP), East Kalimantan, Indonesia. The overall analysis of the respondents showed that there were five elements of social capital have significant effect on silvofishery. The other two elements were insignificant and should be of particular concern to be improved, i.e. social networks and social norms. Indicators to be aware of were the increased knowledge of communities on park-related regulations, increased involvement of individuals in the community, and the strengthening of public figures who can be role models for the community. Mangrove forest of KNP should be kept as conservation area, but it should still pay attention to the socio-economic conditions of the surrounding community. The strength of social capital is expected to realize conservation-based economic development.

Abstract

Various rehabilitation and restoration of mangrove forests have been done, but there have not been any significant results. The main reason for the various failures in this activity is that the effort is not based on scientific data such as the suitability of the physicochemical conditions of mangrove habitats along the beach coast of  Sulamo District. The purpose of this research is to analyze the condition of salinity, the thickness of mud, and the beach slope of the selected mangrove locations Oeteta, Pariti, Beringin, and Pitai beaches.  The salinity conditions show variations, ranging from 19 ppm to 42.33 ppm. The thickness of the mud shows the highest value at 79.11 cm and the slope of mangrove coastal 1–4%. This research shows that the condition of the mangrove ecosystem in the coastal district of Sulamo is still suitable for mangrove growth. This research provides a basic overview of mangrove ecosystem conditions located on the beach coast of the Sulamo district as the basis for planning rehabilitation programs and mangrove restorations in the research area.

Abstract

The Kutai National Park (KNP) which is located in East Kutai Regency on East Kalimantan Province is endowed with numerous pristine of mangrove forest. However, related information to the species composition and diversity of KNP mangrove is still scanty. Twenty-one of mangrove species were recorded using the quadratic transects survey method (total plot area of 1.7 ha). Main species of mangrove communities were Avicennia lanata, A. marina, Bruguiera gymnorrhysa, B sexangular, Ceriops tagal, Rhizophora apiculata, R. mucronata and Sonneratia Alba. Mangrove density was recorded reached as 1,699 trees ha-1, saplings of 4,395 ha-1 and seedlings 25,348 ha-1. Significant tree density was found in Pandan Bay Estuary. While in the Lombok Bay and the Kaba Bay significant for sapling and seedling categories. Importance value index of mangrove species in the three study locations for three growth categories (tree, sapling and seedling) showed significant differences (p-value> α0.05). Mangrove stand at three study locations has almost the same characteristics. The species diversity and evenness index has shown the same distribution pattern. The findings of this study suggest that KNP mangrove forest stand is not heavily damaged even though there is a lot of human activity. This mangrove could be managed and conserved for multi-sectoral purposes such as ecotourism, research, biodiversity and education rather than solely as a Nature Conservation Area.
