Abstract

Natural resources utilized in unsustainably management, lead to the extinction of biodiversity. The objectives of the research was to figure out the factors related to human activity in natural resources management at sub-sub watershed of khilau influenced to the change of biodiversity in the area. An historical analysis continued with the agrarian diagnosis was emploed as the research method. The result of the study showed that there ware four factors influenced to the biodiversity in sub sub watershed of khilau such as economic factor which is the increasing of commodities price; politic factor which is the occur of reformation lead to forest land occupation by the people; social factor which is the change of agricultur practice from subsistence to commercial products; and cultural factor which is influenced of ethnic in natural resources management. Before the exsisting of community, the area was covered by virgin forest with more than 32 species of flora and 25 species of fauna with the domination of endemic species, the exsistance of human activities lead to increasing of flora to 33 species with the dominance of commercial plants, but in other hand dicreasing fauna to 8 species.

Abstract

One of the local souvenirs from Jambi is accessories made from the seed bark of the sebalik sumpah tree. The sebalik sumpah tree is currently quite rare. Through DNA isolation, sebalik sumpah is one of the efforts of genetic conservation and as a first step in cultivating sebalik sumpah trees. DNA isolation is the initial stage in molecular analysis. The purpose of DNA isolation is to obtain genomic DNA from a sample. Plant DNA isolation generally uses fresh plant samples, with young and soft plant parts. This is recommended to obtain good quality genomic DNA. However, with the limitations of fresh samples, a method is needed that is able to extract DNA from plants that have changed shape and have undergone processing. Each plant requires a different method to obtain DNA. The CTAB (Cethyl Trimethyl Ammonium Bromide) buffer method is a method commonly used in plants because it is able to extract DNA with high polysaccharide and phenol content, so many have modified the method. This study aims to determine the success of the CTAB method without nitrogen in extracting processed materials and the length of incubation time at the precipitation stage. Extraction was carried out by liquid nitrogenless CTAB method with the addition of PVP (Polyvinylpolypyrrolidone). The results show that the CTAB method without liquid nitrogen is able to extract plant samples that have undergone processing and the length of incubation time at the precipitation stage affects the DNA produced.

Abstract

Hutan rakyat merupakan salah satu sumber daya hutan yang potensial. Hutan rakyat dikelola oleh rakyat pada lahan yang berada di atas tanah milik. Status kondisi kesehatan hutan rakyat jati di Desa Rulung Helok dengan rata-rata kondisi adalah sedang pada tahun 2020. Bagaimana nilai perubahan kondisi kesehatan hutan rakyat jati pada saat ini? (2022) Tujuan penelitian ini adalah untuk mengetahui nilai perubahan kesehatan hutan rakyat jati di Desa Rulung Helok Kecamatan Natar, Kabupaten Lampung Selatan, Provinsi Lampung. Metode penelitian antara lain: observasi lokasi, klaster plot Forest Health Monitoring (FHM), pengukuran perubahan kesehatan hutan rakyat jati dan penilaian indikator kesehatan hutan. Hasil penelitian ini menunjukkan nilai perubahan kesehatan hutan rakyat jati yang berkategori baik (klaster plot 1, 2, dan 4), sedang (klaster plot 3, 5 dan 6), dan buruk (klaster plot 7). Dengan demikian nilai perubahan kesehatan hutan rakyat jati di Desa Rulung Helok memiliki rata-rata 4,49 dengan kategori baik dari setiap klaster plot. Oleh karena itu, pertumbuhan pohon jati dapat dipengaruhi pada perubahan kategori status kondisi kesehatan hutan rakyat jati yang dipelihara oleh petani terhadap penurunan hasil panen kayu jati. Hal ini menjadi dasar untuk membuat keputusan yang sangat penting dalam peningkatan kesehatan hutan rakyat jati yang dikelola oleh petani secara keseluruhan.

Abstract

Bamboo is a sustainable alternative to wood and is classified as a non-timber forest product. The primary raw material for this research is andong bamboo (Gigantochloa pseudoarundinacea). which exhibits vivid physical coloration that may reduce its aesthetic appeal. Additionally, it is susceptible to fungal and insect infestations. Heat treatment has been identified as an effective method for modifying the color properties of bamboo, with oil heat treatment offering potential advantages. This study investigated the impact of oil heat treatment on the color properties of andong bamboo and evaluates consumer preferences regarding its modified appearance. Andong bamboo specimens were subjected to oil bath at temperatures of 180°C, 200°C, 220°C, and 240°C for three hours. Colorimetric analysis was conducted using the CIE-Lab system, measuring parameters such as lightness (L*), red-green chromaticity (a*), yellow-blue chromaticity (b*), and overall color change (ΔE*). The results indicate a significant reduction in L* values with increasing treatment temperature, leading to a darker appearance. Similarly, a* and b* values decreased, indicating a shift in chromatic characteristics. A value of ΔE* above 12 suggests a total color change. Consumer preference analysis revealed that respondents favored andong bamboo heat-treated at 180°C and 200°C, perceiving these treatments as producing a more exotic and visually appealing. These findings suggest that oil heat treatment not only enhances the aesthetic value of andong bamboo but also increases its potential for high-value applications in furniture and interior design.

Abstract

Deforestasi meupakan masalah lingkungan utama di negara tropis yang juga terkait dengan peningkatan emisi gas rumah kaca (GRK). Salah satu penyebab terjadinya deforestasi adalah konversi hutan menjadi perkebunan kelapa sawit. Teknologi penginderaan jauh semakin banyak digunakan untuk mengevaluasi dan memantau sumber daya tersebut. Berbagai teknik untuk meningkatkan akurasi dalam analisis citra penginderaan jauh diperlukan untuk memantau perkembangan perkebunan kelapa sawit. Penelitian ini bertujuan untuk membandingkan dua teknik pendeteksian perkebunan kelapa sawit dengan menggunakan citra satelit. Penelitian ini dilakukan pada Bulan November 2020 di Kabupaten Way Kanan, Provinsi Lampung. Penelitian ini menggunakan citra satelit Sentinel-2 Kabupaten Way Kanan Tahun 2019. Citra satelit Sentinel-2 memiliki resolusi spasial yang cukup baik (medium to high), hemat biaya dan proses pengolahannya cukup mudah. Pengolahan data menggunakan algoritma Maximum-Likelihood Classification (MLC) dan algoritma Object-Oriented Classification (OOC). Hasil penelitian menunjukkan bahwa teknik terbaik untuk mendeteksi perkebunan kelapa sawit menggunakan algoritma OOC.
