Bamboo Straw Business Development Strategy In The West Manggarai KPH

Loretha Sanda — 2025-05-15

Plastic straws are one of ten types of waste that dominate coastal areas. Reducing plastic straws can be done by using environmentally friendly straws such as bamboo straws. The Forest Management Unit of West Manggarai Regency is trying to develop a business of making bamboo straws using Buluh Lengis bamboo (Schizostachum lima (Blanco(Merr)) or known by the people of Manggarai as Helang through the Forest Farmers Group (KTH) in Kuwus District. This research was conducted to find out and analyze internal factors and externally the development of a bamboo straw business by KTH in Kuwus District and reviewing its development strategy.Primary data was collected from key respondents, namely the Head of the West Manggarai KPH, Field Forestry Extension, KPH staff who are responsible for the finishing process of bamboo straws and KTH members who produce bamboo straws.Data Secondary factors were obtained from various previous reports.The results showed that internal factors that had an influence on the development of a bamboo straw business were management, marketing, finance and production, while external factors that had an influence were economic, social, government and technology. Business development strategies that can be carried out are increasing the quantity and quality of production, expanding markets outside the West Manggarai region by utilizing the internet network, overcoming the problem of limited human resource capacity through training, and working with the government to overcome limited capital and provide better production facilities

Yudhistira A.N.R. Ora — 2025-05-15

The presence of vegetation in an area will have a positive impact on the balance of the ecosystem. However, the effect will vary depending on the structure and composition of the grows vegetation. To obtain quantitative information about the structure and composition of a plant community, vegetation analysis is carried out. The purpose of this activity is to study the composition of the plant community (vegetation) in the Grid 11R Detusoko Jungle Forest, Kelimutu National Park. The observation method used was a systematic double plot method. The results showed that the population density of all species for each vegetation level was 336 individuals/hectare; 854.84 individuals/hectare; 2,971 individuals/hectare; 21,400 individuals/ha. The dominance of all species in the area in the grid 11 R of Detusoko Jungle Forest for the tree level is 43.61 m²/hectare; and for the pole level of 18 m²/hectare. Species that can adapt well to their environment in the 11R grid area of Detusoko Jungle Forest for the levels of trees, poles, saplings, seedlings, are Eucalyptus urophylla (Ampupu) (INP = 94.62%); Calliandra ( Kaliandra ) (INP = 62.38 %) Calliandra ( Kaliandra ) (INP = 51.20 %); and Calliandra ( Kaliandra) (INP = 34.99 %). Furthermore, the vegetation associations that make up the Detusoko jungle are Eucalyptus urophylla (Ampupu), Casuarina junghuhniana (Mountain cypress), Calliandra ( Kaliandra), Melastoma malabathricum (Mboa) and Saurauia schmutzii (Singgih).

Identification of Natural Food for Bees (Apis dorsata) in Oebola Dalam Village Forest, Kupang Regency

Sandra Silla — 2025-05-15

Apis dorsata is a honey bee living in the forest, making nests into single units hanging from tree branches and rock cliffs. The survival of A. dorsata colonies in the forest is closely related to the availability of plants that produce nectar and pollen as their natural food. The study aimed to determine the types of vegetation that serve as raw food around A. dorsata nests in the Oebola Dalam Village Forest, a honey-producing area. The research was carried out in May 2021. Data was collected using the Vegetation Analysis method line plot sampling with beehives as tie points and circular observation areas with a radius of 1000 m on a site of 314 Ha and a sampling intensity of 0.5%. The distance traveled by A. dorsata to find food is 1-2 km, so an area of 1.57 ha is obtained with 39 square plots divided into six lanes, each lane consisting of 6-7 square plots with a distance between lanes 60 degrees, and the distance between measuring plots is 25 m with a length of observation path of 300 m. The results of observations of the vegetation composition that became A. dorsata's natural food from tree species, poles, saplings, and seedlings found 12 plant species. They were dominated by Jambu Air INP 76% and Johar INP 64%. The results of identifying plants that produce nectar and pollen are Taduk (Alstonia scholaris), Tamarind (Tamarindus indica), Kusambi (Shleichera oleosa), Kapok Forest (Bombax malabarica), Guava (Syzygium aqueum), Lamtoro (Leucaena leucocephala), Johar (Senna siamea), White Teak (Gmelina arborea), Mahogany (Swietenia mahagoni), Anonak (Annona squamosa), Teak (Tectona grandis) and Eucalyptus (Eucaliptus alba).

Factors of Kondo Forest Encroachment on Environmental Damage in Kondo Village, Mehalaan District, Mamasa Regency

Abd Rajab — 2025-05-17

Forest encroachment is a serious issue that threatens the ecosystems and welfare of communities around forest areas. This phenomenon also occurs in Kondo Village, where most people depend on agriculture for their livelihoods. This study aims to identify community activities, causal factors, and impacts of forest changes that occur. A qualitative approach was used through in-depth interviews. The results show that the impacts are triggered by economic needs, soil fertility, low education, open access, and weak supervision. The impacts that have emerged are floods and landslides during the rainy season, while long-term ecological impacts such as land degradation and loss of biodiversity have the potential to occur. Socio-economically, there is a dependence on subsistence farming, land conflicts, and limited alternative livelihoods.

Identification of Plant Types and Patterns in Agroforestry Systems in West Golewa District, Ngada Regency

Maria Wea — 2025-05-26

The study was conducted to identify the types of plants or vegetation and planting patterns in agroforestry land owned by the community of Golewa Barat District, Ngada Regency, NTT Province. The research method was carried out descriptively qualitatively with direct observation in the field, interviews, documentation and providing descriptions of the results of observations in the field.

The results of the study showed that the Agroforestry System in Golewa Barat District was carried out with the Agrosilvopastura Pattern, namely planting that combines agricultural crops, forestry plants and green fodder. Agricultural and plantation crops such as cloves (Syzygium aromaticum), candlenuts (Aleurites mollucanus), coconut (Cocos nucifera), rice (Oryza sativa), ginger (Zingiber officinale), corn (Zea mays), coffee (Coffea), taro (Colosasia esculante), and vegetables. Tree plants include ampupu (Ecalyptus urophylla), albasia (Paraseriaanthes falctaria) mahogany (Swietenia mahagoni), white teak (Gmelina arborea) and surem (Toona ciliata). The animal feed plants found are king grass (Pennisetum purpuphoides). The agroforestry pattern applied by the community is a square and rectangular pattern. Forestry plants are planted at a certain distance that provides space for planting agricultural crops and animal feed in the gaps.

Mapping of Vegetation Density Changes In Special Purpose Forest Area In Sisimeni Sanam Using Sentinel-2a Imagery Data

Francisca Bianco — 2025-05-22

Sisimeni Sanam Training KHDTK in Kupang Regency, with an area of 3,109.89 hectares, this area is divided into conservation, protection, and production zones, but faces various problems such as fire, encroachment, timber theft, and land degradation. To determine changes in vegetation in the last 7 years (2017 to 2024), a significant method in monitoring changes in vegetation density is by utilizing remote sensing technology with Sentinel-2A imagery. This study aims to determine the accuracy of Sentinel-2A image data and map changes in vegetation density in the last 7 years in the Sisimeni Sanam Training KHDTK. Based on the results of calculations using the confusion matrix table, the accuracy value of the ground check results is 87.8% (OA) and 81% (KA). This shows that the spatial information of density distribution using NDVI obtained has good accuracy and can be trusted. The results also show that within 7 years the KHDTK has experienced changes in vegetation density, namely 0.33 Ha/year for the sparse density class, 1,932.16 Ha/year for the medium density class and 731.85 Ha/year for the medium density class. These changes were identified based on seasonal and climatic dynamics that took place over a period of 7 years.
