“…Pengukuran kualitas kesehatan mangrove dapat dilakukan dengan menggunakan analisis parameter struktur komunitas, pengindraan jauh dan kombinasi dari keduanya. Penelitian Prasetya et al (2017) menggunakan kerapatan pohon, indeks keanekaragaman, indeks keseragaman, dan jumlah spesies untuk menentukan nilai kesehatan mangrove. Namun, nilai ini akan tidak cukup stabil pada mangrove yang bersifat homogen seperti di pulau-pulau kecil.…”

Ekosistem mangrove memiliki peranan penting bagi eksistensi dan penyediaan jasa ekosistem kepada masyarakat di pulau kecil. Fungsionalitas mangrove sangat tergantung dari ukuran, struktur komunitas dan kualitas ekosistem. Penelitian tentang penilaian kualitas struktur komunitas mangrove pulau kecil telah dilakukan di Pulau Middleburg-Miossu sebagai rangkaian dari Ekspedisi Nusa Manggala 2018. Penelitian ini bertujuan untuk menganalisis struktur komunitas dan indeks kesehatan mangrove (MHI) mangrove di pulau tersebut yang dihubungkan dengan indeks-indeks vegetasi berbasis penginderaan jauh. Lokasi penelitian dibagi menjadi empat zona, dimana hasil penelitian menunjukkan bahwa zona terdepan didominasi oleh jenis Sonneratia alba (INP 263,32%) dengan persentase tutupan kanopi < 50%, ukuran diameter > 20 cm dan ketinggian tegakan yang lebih rendah. Sementara itu, tiga zona lainnya ke arah darat, didominasi oleh jenis Ceriops tagal dengan persentase tutupan kanopi >80%, serta kerapatan pancang yang cukup tinggi. Secara keseluruhan, kondisi kesehatan mangrove di lokasi penelitian termasuk dalam kategori sedang/cukup baik dengan rentang nilai MHI 38,7-60,7%. Kombinasi indeks vegetasi NBR, GCI, SIPI dan ARVI menunjukkan nilai koefisien regresi yang paling tinggi untuk memprediksi nilai MHI, yaitu 0,831, berdasarkan analisis AIC. Interpolasi nilai MHI berdasarkan model regresi linier terbaik menunjukkan bahwa 6,56 ha mangrove di lokasi penelitian atau 40.74% termasuk dalam kategori sehat.

“…Median of the two adjacent determinations After constructing the hierarchical model, a judgment matrix needs to be constructed. This is to compare all factors separately and to use relative scales to minimize the difficulty of comparing factors with different properties, thereby improving the accuracy [23,24]. The judgment matrix is a comparison of the relative importance of all factors in this layer against a certain factor in the previous layer.…”

The market competitiveness and sustainable operation of an enterprise are closely correlated with the support of high-tech core technologies in the enterprise. This study first discusses the basic knowledge of core competitiveness, introduces the components and evaluation methods of core competitiveness, and builds an evaluation index system for core competitiveness of high-tech enterprises. Then, the Analytic Hierarchy Process (AHP) is fully discussed, during which the steps, advantages, and disadvantages of the AHP evaluation method are introduced. Finally, the Fujian Province of China is taken as an example, the relevant data are collected and processed, the impact of indicators are analyzed, and a high-tech industry core technological capability analysis indicator system is built based on the AHP method. Thus, the influence of the core technological capabilities of the high-tech industry on the sustainable competitive advantage of the enterprise is obtained. This study puts forward suggestions for maintaining the competitiveness of high-tech industries, thereby improving the competitive advantage of enterprises and achieving the sustainable management of enterprises. The result finds that if the high-tech industries continue to carry out innovation and scientific research, enterprises will maintain their competitive advantages. In summary, exploring the impact of the core technological capabilities of high-tech industries on the sustainable competitive advantages of enterprises is greatly significant for improving their competitiveness and industrial status, which enables them to be invincible in a complex environment.

“…The diversity index value ranged between 2.89 to 3.2 indicating moderate to high diversity species richness (Figure 3) (Magurran 2004). According to Gu et al (2016); Prasetya et al (2017); Huang et al (2020), diversity of gastropods can describe the stability of the ecosystems. The high diversity index value makes ecosystem existence said well, conversely, the low diversity index causes unbalanced gastropods habitat.…”

Abstract. Imamsyah A, Arthana IW, Astarini IA. 2020. The influence of physicochemical environment on the distribution and abundance of mangrove gastropods in Ngurah Rai Forest Park Bali, Indonesia. Biodiversitas 21: 3178-3188. Ngurah Rai Forest Park is the widest mangrove ecosystem in Bali that close to the business center and tourism area. The strategic location of the Ngurah Rai Forest Park is estimated to produce anthropogenic waste that can disrupt the gastropod population and stability of the mangrove ecosystems. This study aims to analyze the mangrove density, distribution, and abundance of gastropods based on the quality of the biophysical environment. Mangrove data collection was carried out using a plot transect of 10 m x 10 m, 5 m x 5 m, and 1 m x 1 m. Meanwhile, samples gastropods were collected on a plot transect of 0.5 m x 0.5 m in plot transect of 5 m x 5 m. A total of 11 gastropods species and 6 mangrove species were recorded in this study. The dominant gastropods species found were Assiminea brevicula (28 ind/m2). Species mangrove of Sonneratia alba and Rhizophora apiculata found were in all study sites with tree density values of 1000 ind/ha. Subsequently, the ecological index calculation results show that the diversity index (H’) (2.89-3.2), evenness index (E) (0.87-0.93), and dominance index (C) (0.12-0.17). Based on the Principal Component Analysis (PCA) found was Assiminea brevicula spread on sand and silt substrates and adaptive to the temperature condition, salinity, pH, and dissolved oxygen. Furthermore, other analysis results showed that Cerithidea cingulata, Cerithidea quadrata, Littoraria articulata, and Littoraria scabra were found on clay substrate with high C-organic content. In conclusion, gastropods are evenly distributed and no species dominate the ecosystems.
