Abstract

Sungai Sekonyer village is a village that bordered by Tanjung Puting National Park (TNTP). Agroforest system is one of the land uses that considering ecology, socio-economy aspects in supporting buffer zone TNTP. The objectives of this research were to analyze the structure and composition of agroforest system, as well as to analyze biodiversity vegetation of the agroforestry system in Sungai Sekonyer Village, West Kotawaringin Regency, Central Kalimantan. This research used purposive sampling and vegetation analysis methods. The results showed that the dominant species at sapling level in agroforest system-1 was oil palm (Elaeis guineensis) with IVI 121.54%, while in agroforest system-2 there was no sapling. The dominant species at pole level both in agroforest systems 1 & 2 was rubber (H. brasiliensis) with IVI respectively 184.88% and 187.08%. The dominant species at tree level in agroforest system-1 was sengon (F. moluccana) with IVI=128.47%, while in agroforestry system-2 was jengkol (A. pauciflorum) with IVI=121.32%. The diversity indices (H’) and species richness indices (Dmg) for both agroforestry systems were categorized as low. Agroforest management, socio-economic aspect, ecological site, and market are the main factor for species selection that indirectly affecting biodiversity status in agroforest system. Enrichment planting using high economic value species that is suitable to the ecological site is necessary to increase community income as well as biodiversity status. Key words: agroforest, Sungai Sekonyer Village, vegetation biodiversity

Abstract

Pemanasan global memberikan banyak dampak negatif bagi kehidupan, gagal panen dalam pertanian merupakan salah satu dampak akibat pemanasan global yang terjadi. Hutan mangrove merupakan salah satu vegetasi khas daerah pesisir pantai yang tumbuh di daerah pasang surut air laut. Mangrove memiliki banyak manfaat bagi kehidupan, baik langsung maupun tidak langsung. Saat ini hutan mangrove terancam keberadaanya akibat aktivitas manusia seperti alih fungsi hutan mangrove menjadi pemukiman dan pertambakan. peristiwa perubahan iklim yang terjadi menarik perhatian dari semua kalangan lapisan masyarakat mulai dari akademisi, aktivis lingkungan hingga perusahaan-perusahaan besar. Program penanaman mangrove merupakan upaya yang dapat dilakukan dalam aksi menyelamatkan bumi. Perusahaan besar memiliki tanggung jawaban sosial dan lingkungan sekitar. Melalui program CSR penanaman 1000 batang mangrove merupakan salah upaya PT. Pertamina Patra Niaga dalam upaya menjaga lingkungan. Kegiatan penanaman mangrove ini dilaksanakan pada tanggal 31 Juli 2024 di kawasan Mangrove Park Lampulo, Kecamatan Kuta Alam, Kota Banda Aceh yang dihadiri oleh pihak PT. Pertamina Patra Niaga Fuel Terminal Krueng Raya, Human Initiative Cabang Aceh, Dinas Kelautan dan Perikanan provinsi Aceh, pemerintahan kecamatan Kuta Alam, Polsek Kuta Alam, Koramil Kuta Alam, Pemuda Peduli Mangrove Kuta Alam (Pemangku), Program Studi Kehutanan USK, BEM FKP USK, HIMASYLVA USK dan Pesantren Baitul Qur’an.

Abstract

Urban environmental comfort increasingly challenged by rapid population growth and development. Green Open Spaces (GOS) are crucial in enhancing community also life quality. This study assess the comfort value of GOS in Medan City by examining physical, biotic, and social factors. The research employed a combination of vegetation inventory to evaluate biodiversity, environmental measurements to assess air quality and noise levels, and public perception surveys to understand social comfort. The findings reveal that Cadika Park possesses the highest vegetation diversity with 31 tree species, dominated by Terminalia mantaly, which also recorded the highest Leaf Area Index (LAI) of 1.78. Physically, air quality within GOS areas is better than outside, although noise levels still exceed environmental quality standards. Socially, the community perceives GOS as comfortable and beneficial for daily activities. In conclusion, despite certain physical limitations, GOS in Medan City contributes positively to environmental comfort, underscoring the need for continuous management and sustainable development of urban green spaces.

Abstract

The response of composting microbes to fly ash can show an increase or decrease in population depending on the type and concentration of fly ash used. This study aims to identify the effect of fly ash addition on the composting of citronella (Cymbopogon nardus (L.) Rendl.) leaf waste, specifically in relation to changes in the C/N ratio and the number of composting microbes, and the identification of fungal species that developed during the process. The composting treatments included citronella leaf waste without alkali (K), also with the addition of alkali in the form of 2% dolomite (D), fly ash of 2% (FA1), 5% (FA2), 10% (FA3) and 15% (FA4). The analysis used in this study was a quantitative descriptive analysis related to the analysis of C-organic and total N, as well as composting microbes. Quantitative descriptive analysis was employed to assess C-organic content, total nitrogen, and microbial populations. The results demonstrated that the incorporation of fly ash influenced both the C/N ratio and microbial abundance. The addition of 10% fly ash proved to be the most effective treatment, increasing nitrogen content and reducing the C/N ratio to 26, while supporting bacterial growth up to 3.0 × 10¹¹ CFU/g. Fungal identification revealed the presence of Rhizopus sp., Trichoderma sp., and Aspergillus sp., which contribute to the degradation of organic matter in citronella leaf waste.
