Abstract

Land use patterns are strongly influenced by human requirements; among the most important problems is deforestation. Particularly with deforestation, central Halmahera Regency has seen significant changes in land usage. We use Qgis software and remote sensing data, to seeks and identify the rate of deforestation in Central Halmahera Regency. from Global Forest Change, that satellite pictures data. According to this studies, Weda and Maba were the most impacted areas in Central Halmahera experiencing the worst deforestation between 2014 and 2017. The conversion of forest land into nickel mining sites caused notable destruction in several places. With an average annual loss of 1,435.43 hectares between 2001 and 2013, data showing varying rates of deforestation between 2001 and 2022 shows Rising during 2014 and 2015, the pace of deforestation peaked at 8,852.506 hectares but started to fall in 2016 and 2017.

Abstract

Indonesia has excellent land potential for the development of the agricultural sector with various levels of topography that are different for each region. Every slope of the land varies, there are nutrients that are a source of food for plant growth. This research aims to determine the effectiveness of land cover in Borisallo Village, Parangloe District, Gowa Regency. This research will be carried out from October 2023 to April 2024. Analysis of the physical properties of the soil will be carried out at the Soil Physics and Conservation Laboratory, and analysis of the chemical properties of the soil will be carried out at the Soil Chemistry and Fertility Laboratory, Department of Soil Science, Faculty of Agriculture, Hasanuddin University. In the preparation stage, literature study and data collection were carried out, then primary data and secondary data were collected. After that, the data is processed into a land unit map. Then soil samples are taken according to the points determined based on the land unit map. After taking soil samples, laboratory analysis is then carried out to analyze soil permeability, organic C, bulk density and porosity. Even though there is land cover, several areas in Borisallo village still require conservation measures to prevent landslides and erosion, especially on land that has a slope. This can be seen from the permeability value which is included in the slow category.

Abstract

Forestry Extension Workers, as one of the important parties in maintaining and preserving forest resources in Indonesia, are expected to have an understanding of good extension methods and techniques so that farmers around the forest can improve their knowledge and skills in managing and utilising forest products. This study aimed to assess the performance of forestry extension workers in Tompobulu District. And also evaluate their role in enhancing the knowledge and skills of forest farmer groups in Maros Regency. It was located in six villages, namely Bonto Somba Village, Bonto Manurung, Bonto Matinggi, Bonto Manai, Tompubulu, and Pucak Maros Regency with the number of samples in the study was 57. The study employed qualitative descriptive analysis using a Likert scale, and quantitative analysis using the t-test. The performance of forestry extension workers that significantly influences increasing the knowledge and skills of forest farmer groups consists of six indicator components, namely: facilitating forest farmer groups to prepare forest product utilisation maps; facilitating forest farmer groups to prepare annual work programs and plans; facilitating forest farmer group members to improve human resource quality; facilitating forest farmer groups to disseminate or spread information on forest product technology; facilitating forest farmer groups to grow their empowerment and independence; and facilitating forest farmer groups to increase production results of superior forest product commodities. Meanwhile, the performance of forestry extension workers that does not significantly influence increasing the knowledge and skills of forest farmer groups is Facilitating Business Partnerships Between Forest Farmer Groups, Entrepreneurs, and the Government, Facilitating Forest Farmer Groups to Access Business Capital with Financial Institutions, Banks, and the Government; and Facilitating Increasing the Income and Welfare of Forest Farmer Groups.

Abstract

The growth of Nyatoh (Palaquim sp) seedlings is very slow so they need to be given treatment to speed up their growth in the field. Nyatoh (Palaquim sp) seeds are endemic to South Sulawesi and make good quality wood for house building materials. This research aims to determine and analyze the interaction of giving compost fertilizer on the growth of Nyatoh (Palaquium sp) seedlings in the nursery, as well as knowing and analyzing the appropriate dosage according to the growth needs of Nyatoh (Palaquium spp) seedlings in the nursery. The research method used was an experimental method with 3 repetitions. Nyatoh seeds which are available in the form of polybags are approximately 2 months old in the nursery, then seeds with a uniform height of around 15 cm are selected for a total of 90 seedlings. Next, compost fertilizer is prepared from fermented cow dung, then weighed at a dose of 30 gr/seed coded (P1), 40 gr/seed (P2), and 50 gr/seed (P3). Initial growth measurements (first week) were carried out when the seeds were mixed with compost for each Nyatoh seedling. Then the next measurement was carried out in the 4th week (final measurement) on 90 Nyatoh seedlings in the nursery.The results of the research showed that the interaction of giving compost fertilizer to Nyatoh seedlings had a very significant effect on the increase in height and number of leaves of Nyatoh seedlings in the nursery, with a calculated F value of 14,955 > F table value of 4,459 and F calculated 12,043 > 4,459. The treatment of providing compost fertilizer at a dose of 40 gr/seed (P2) had a very significant effect on the increase in height and increase in the number of leaves of Nyatoh seedlings in the nursery.

Abstract

The world is experiencing a food crisis due to climate change, and mangroves as a blue ecosystem have a significant potential to mitigate this crisis. This research seeks to record the ethnobotanical practices of utilising mangroves, as a food source in East Lampung. We employed the snowball sampling method in Margasari village, Purwerejo village, and Karya Makmur village. In addition, we gathered data on mangrove species, parts of used, processing methods, products, and their properties, through interviews and observations. Also, we analysed the data using descriptive analysis to provide a comprehensive overview of the varieties of mangroves, their processing, and the resulting products. This research revealed that the communities employs five distinct varieties of mangroves as sustenance sources. Mangroves produce various food products from their four components: fruit, juvenile leaves, old leaves, and propagules. Notably, processed products, including pidada fruit (Sonneratia caseolaris), are anti-hypertensive, canker sores, and heartburn treatments. Jeruju leaves (Acanthus ilicifolius) are known to improve stamina, and seeds without the root of Rhizophora mucronata propagules act as anti-gastritis agents, improve blood circulation, and prevent anaemia. Although there are ten processed mangrove products, they are still considered traditional and are not as popular among the newer generation.
