Abstract

Desa Eyat Mayang memiliki potensi ekosistem mangrove dan merupakan bagian dari Kawasan Ekosistem Esensial (KEE) Koridor Mangrove Teluk Lembar. Tujuan dari penelitian ini yaitu untuk menganalisis struktur dan komposisi vegetasi mangrove di Desa Eyat Mayang. Pengumpulan data dilakukan melalui plot contoh dengan metode jalur berpetak. Jumlah petak contoh ditentukan menggunakan intensitas sampling (IS) 5,5% dengan total plot contoh 84. Analisis komposisi vegetasi mangrove meliputi indeks nilai penting, indeks keanekaragaman, indeks kekayaan jenis, indeks kemerataan. Hasil penelitian menunjukkan bahwa komposisi vegetasi mangrove di Desa Eyat Mayang terdiri dari lima spesies mangrove mayor yang termasuk ke dalam tiga famili. Spesies Rhizophora apiculata memiliki nilai INP paling tinggi dan menjadi spesies dominan pada seluruh tingkat pertumbuhan. Indeks keanekaragaman pada tingkatan pertumbuhan pohon dan tiang termasuk kategori sedang, sedangkan semai memiliki keanekaragaman rendah serta  indeks kekayaan jenis pada seluruh tingkatan masuk kategori rendah. Indeks kemerataan pohon termasuk ke dalam kategori hampir merata sedangkan pada tiang dan semai termasuk ke dalam kategori cukup merata. Struktur vegetasi mangrove secara horizontal menunjukkan bahwa kerapatan pada tingkatan semai paling tinggi dan kerapatan pohon paling rendah.  Hubungan antara kelas diameter dengan kerapatan menunjukkan kurva huruf “J” terbaik yang menunjukkan bahwa semakin besar diameter semakin rendah kerapatannya dan hal tersebut merupakan kondisi alamiah pada kawasan hutan yang alami. Struktur vertikal menunjukkan bahwa vegetasi mangrove di Desa Eyat Mayang termasuk ke dalam stratum C (4 – 20 m) dan stratum D (1 – 4 m). Analysis of Mangrove Vegetation in Eyat Mayang Village, Lembar Sub District, Lombok Barat Regency Abstract Eyat Mayang Village has the potential for a mangrove ecosystem and is part of the Essential Ecosystem Area (KEE) of the Lembar Bay Mangrove Corridor. The purpose of this research is to analyze the structure and composition of mangrove vegetation in Eyat Mayang Village. Data collection was carried out through sample plots using the grid path method. The number of sample plots was determined using a sampling intensity (IS) of 5.5% with a total of 84 sample plots. Analysis of the composition of the mangrove vegetation included the importance value index, diversity index, species richness index, evenness index. The results showed that the composition of the mangrove vegetation in Eyat Mayang Village consisted of five major mangrove species belonging to three families. Rhizophora apiculata species had the highest IVI value and became the dominant species at all growth stages. The diversity index at the tree and pole growth stages is in the medium category, while the seedlings have low diversity and the species richness index at all stages is in the low category. The evenness index of trees is in the almost even category, while the poles and seedlings are in the fairly even category. The horizontal structure of the mangrove vegetation shows that the density at the seedling level is the highest and the density of trees is the lowest. The relationship between diameter classes and density shows the best "J" curve which indicates that the larger the diameter the lower the density and this is a natural condition in natural forest areas. The vertical structure shows that the mangrove vegetation in Eyat Mayang Village belongs to stratum C (4 – 20 m) and stratum D (1 – 4 m).

Abstract

Mataram City, the capital city of West Nusa Tenggara Province, is experiencing rapid development which has an impact on increasing noise in urban areas. This study aims to analyze the ability of vegetation to reduce noise in the Udayana Urban Forest. This study uses a quantitative descriptive method, with location selection using purposive sampling. Noise reduction measurements using a Sound Level Meter at four observation points with variations in canopy cover and the distance variable of vegetation from the noise source. This study shows that vegetation has an essential role in reducing noise, with a noise level reduction value in the open dominance area of ​​the eastern area of ​​8.2 dBA and the western area of ​​8.7 dBA. At a sparse vegetation density level, a decrease of 6 dBA in the western and eastern areas is constant. At a moderate vegetation density level, a decrease of 4.5 dBA in the western and eastern areas, the noise value is constant. In vegetation with high/dense density, there was a decrease of 5.9 dBA in the eastern and western areas of ​​7.1 dBA. Based on the distance variable, noise reduction in the open dominance area decreased by 6.1 dBA in the eastern area and 6.7 dBA in the western area. In areas with sparse vegetation density, there was a decrease of 6.8 dBA in the East and 6 6.0 dBA in the West. For moderate vegetation density, there was a decrease of 6.4 dBA in the East and 6.1 dBA in the West. In areas with high/dense vegetation density, there was a decrease of 3.6 dBA in the East and 4.4 dBA in the West. The regression analysis results showed that canopy cover and distance significantly affected noise levels with a strong relationship, where the denser the canopy cover and the farther the distance, the noise level would decrease.

Abstract

Asian palmyra palm (lontar) fronds are a byproduct generated from the asian palmyra palm plant. To add value to these fronds, they can be converted into activated charcoal. This study aims to determine the properties of activated charcoal derived from asian palmyra palm fronds and the effects of activation temperature and chemical concentration on these properties. The activation process was conducted using H3PO4 solution with two concentration variations, 10% and 20%, for 24 hours, and three temperature variations, 600°C, 700°C, and 800°C, each for 60 minutes. The data obtained were analyzed using R software version 4.3.1. The effects of the variation factors in H3PO4 concentration and activation temperature on the yield and characteristics of the activated charcoal were calculated using two-way ANOVA with a 95% confidence level. The properties of the activated charcoal produced met the SNI 06-3730-1995 standard for technical activated charcoal, with yield, moisture content, ash content, volatile matter content, fixed carbon content, and iodine adsorption values of 80.41%, 0.42%, 9.35%, 8.28%, 82.38%, and 668.13 mg/g, respectively. The best properties of activated charcoal were obtained from the activation treatment at 600°C and 20% H3PO4 concentration

Abstract

In Bayan Village, West Nusa Tenggara, there are four customary forest areas that have the potential to be developed through the Customary Forest scheme. This scheme is part of the Social Forestry Program which provides access and forest management rights to indigenous communities. The four forests are currently being managed by the indigenous peoples but have not yet been granted the status of customary forest. The aim of this study is to evaluate the potential of the Bayan indigenous community to acquire forest management rights under the Customary Forest scheme. The research employed a normative-empirical approach. The results indicate that the Bayan indigenous peoples meets all the criteria in the Government Regulation No. 23 of 2021 on the Implementation of Forestry and the Ministry of Environment and Forestry Regulation No. 9 of 2021 on Social Forestry Management. The Bayan indigenous peoples is eligible to be designated as a Customary Law Community by the Regent of North Lombok and to obtain Customary Forest management rights from the Ministry of Environment and Forestry. This potential is supported by two factors: (1) the potential for forest and tourism development; and (2) the potential for well-maintained local wisdom.
