Abstract

The sustainable management of forest resources has become increasingly important, particularly in community-managed forests where non-timber forest products (NTFPs) play a crucial role in local livelihoods and biodiversity conservation. This study aims to identify the types of NTFPs, the density and diversity of vegetation, and the average growth of NTFPs in the Community Forest (HKm) of Aik Bual. The research utilized a descriptive method and was conducted from August to September 2022 on HKm land in Aik Bual Village, Central Lombok, which received enrichment assistance for NTFP plants. The study population consisted of 164 HKm farmers, with an average land ownership of 50-60 ares. The sample used in this study comprised 20 plots managed by farmers. On these plots, a main plot of 25 m x 40 m and subplots of 20 m x 20 m and 10 m x 10 m were established. In the 25 m x 40 m plots, all NTFPs were surveyed, while other vegetation at tree and pole levels was measured in the 20 m x 20 m and 10 m x 10 m subplots. Parameters measured included diameter, height, and vegetation type. The analysis included vegetation diversity, density, dominance index, and NTFP growth. The results showed that there are nine types of NTFPs in the Community Forest of Aik Bual, namely avocado, durian, guava, mango, jackfruit, cocoa, silk cotton tree, melinjo tree, and sapodilla. Additionally, five types of non-wood forest products were identified. The vegetation density at the tree level in HKm Aik Bual was 515 individuals/ha, while at the pole level it was 545 individuals/ha. The highest importance value index (IVI) at the tree level was recorded for rajumas and mahogany, with values of 82% and 78,70%, respectively. At the pole level, durian and avocado had the highest IVI, with values of 123,69% and 70,08%, respectively. The dominance index at the tree level was dominated by rajumas and mahogany with a value of 0,07, while at the pole level, durian dominated with a value of 0,17. The average diameter growth for avocado at ages 1, 4, 5, 10, and 20 years was 1,49 cm/year, 2,42 cm/year, 2,55 cm/year, 1,98 cm/year, and 1,64 cm/year, respectively. For durian, the average diameter growth at these ages was 1,43 cm/year, 2,76 cm/year, 2,35 cm/year, 1,68 cm/year, and 1,71 cm/year. The average height growth for avocado at ages 1, 4, 5, 10, and 20 years was 1,33 m/year, 1,42 m/year, 1,62 m/year, 1 m/year, and 0,60 m/year, respectively. For durian, the average height growth at these ages was 1,24 m/year, 1,39 m/year, 1,50 m/year, 1,07 m/year, and 0,71 m/year. Keywords: NTFS, Growth, Dominance Index, Vegetation Density

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

Patchouli (Pogostemon cablin Benth.) plant is one of the essential oil producing plants, that is useful in the chemical industry as a raw material for fragrance products and in the pharmaceutical field. The success rate of patchouli early growth, is largely determined by the cultivation techniques used, including the use of growth regulators, and growing media. This study aims to determine the effect of IBA growth regulators and the composition of plant media on the growth of patchouli plants. This research is carried out in the Greenhouse of the Forestry Study Program of the University of Mataram, using a Factorial Completely Randomized Design (RALF), the first factor is IBA growth regulator with 3 levels, namely 0, 20, 25 ppm and the second factor is composition of plant media with 3 levels, namely forest soil media, soil media:sand:compost (1:1:1), and soil media:sand:compost (2:1:3). The results show that the effect of IBA significantly affect the success percentage of cuttings and the number of roots of patchouli plants. The effect of plant media composition and the interaction between treatment of IBA with plant media composition did not have a significant effect on the growth parameters of patchouli plants.

Abstract

Forests have the ability to reduce carbon dioxide (CO2) and store it in the form of biomass. This study aims to determine the dynamics of carbon stocks in the Senaru Special Purpose Forest Area (KHDTK) with a spatial and time approach. Data collection was carried out in July-August 2024. Located in Senaru KHDTK. Vegetation data collection was carried out by systematic sampling with random start, vegetation data taken in the form of species, diameter and height were carried out on 43 sample plots measuring 20x20m with sub plots of 10x10m, 5x5m and 2x2m.  Standing carbon stocks were determined using the allometric equation. Carbon stock dynamics were analyzed by comparing the results of the study with stock data from previous studies. Spatial analysis was conducted using ArcGis application with Inverse Distance Weight (IDW), Kriging and Spline spatial interpolation methods. The results showed that the average surface carbon stock was 66.35 tons/ha. It decreased by 13.48 tons/ha in 5 years, and decreased by 17.36 tons/ha in 10 years. The spatial interpolation method that has the least error rate is the Kriging method. To increase the carbon stock of Senaru KHDTK, it is necessary to increase the population of forestry plants including large-trunked multipurpose plants such as durian, dao, jackfruit and others.

Abstract

Forest areas enrichment with multipurpose plants could increase the success of forest area management by the community. This study describes the performance of multipurpose trees as plant enrichment in community managed forest in Karang Sidemen Village, Central Lombok, and to analyze the factors that influence it. Data were collected in August 2023. Respondents were farmers who received plant enrichment assistance in 2017 sponsored by the Millennium Challenge Account Indonesia (MCAI). Vegetation data were collected from 36 sample plots of 20x20m with subplots of 10x10m and 5x5m. The results showed that the enrichment plants found were avocado, durian, mangosteen and langsat, with the population of 157 individuals/ha (5% of stem diameters (f) 10-<20cm and 96% of f 2-<10cm), which was less than that of banana population of 466 individuals/ha. The population without banana was 1383 individuals/ha with 5.93%, 45.86% and 89.66% belong to f >=20cm, 10-<20cm and 2-<10cm, respectively. The average f at 120cm height for enrichment plants of avocado, durian, mangosteen and langsat were 6.16cm, 5.48cm, 4.26cm and 3.77cm respectively, while the average plant height was 5.26m, 4.07m, 2.39m and 4.86 m respectively. Low soil organic content and dense plant populations tend to result in smaller diameters of multipurpose plants.
