Abstract

Sowang (Xanthostemon novoguineense Valet.) diidentifikasi sebagai spesies endemik Papua. X. novaguineense merupakan jenis tumbuhan New Guinea bagian barat dengan data ilmiah yang sangat terbatas. Di alam, jumlah tegakan dan habitat sowang saat ini telah menyusut karena eksploitasi hasil hutan dan konversi lahan. Sementara eksploitasi kayu sowang dan konversi habitat sowang tetap berlangsung, usaha meregenerasi belum tampak di masyarakat, kemampuan regenerasi sowang secara alami juga sangat rendah. Hal ini merupakan ancaman kepunahan bagi populasi sowang. Penelitian ini dilakukan untuk mengidentifikasi media in-vitro yang sesuai bagi perkecambahan biji dan pertumbuhan tunas sowang. Percobaan dirancang dengan  memperlakukan dua jenis media perkecambahan yakni VW yang dimodifikasi dan MS dengan zpt, 20 ulangan, setiap satu unit percobaan berisi 30 benih sowang yang ditanam di media, dilakukan di laboratorium kultur jaringan FMIPA Universitas Cenderawasih Jayapura. Variabel penelitian adalah hari muncul tunas, persen perkecambahan, penampilan tunas dan tinggi tunas pada usia tunas 60 hari. Data dianalisis dengan independent sample t test. Hasil penelitian menunjukkan tidak terdapat signifikansi pada variabel-variabel hari muncul tunas, persen perkecambahan, penampilan tunas dan tinggi tunas antara perlakuan media VW yang dimodifikasi dan MS dengan zpt. Rata-rata hari muncul tunas adalah 5.50 hari dan 5.55 hari, rata-rata persen perkecambahan adalah 63.55% dan 61.40%, rata-rata skor penampilan tunas adalah 2.85 dan 2.75 serta rata-rata panjang tunas adalah 2.84 cm dan 2.67 cm.

Abstract

This study aims to assess visitors’ perceptions of the potential and feasibility of Taman Hutan Raya (Tahura) Gunung Kunci in Sumedang Regency as a forest healing destination. The research employed a descriptive quantitative approach through a visitor perception survey focusing on facilities, services, and environmental comfort. Data were collected from three main sites amphitheater, viewing post, and bunker with 40 respondents selected using accidental sampling. The results revealed that most visitors rated the area as “Excellent” (60%) and “Good” (40%) in terms of facilities, services, and comfort. Overall, the facilities in Tahura Gunung Kunci are adequate and safe, although some areas, such as shelters and walkways around the bunker, require maintenance. The visitors’ positive perception indicates that Tahura Gunung Kunci has strong potential to be developed as a forest healing-based ecotourism destination that promotes health, education, and community well-being.

Abstract

Kerusakan lahan merupakan permasalahan serius akibat ketidakseimbangan pengelolaan hutan antar aspek ekologi dan sosial – ekonomi. Lahan yang teridentifikasi sebagai lahan rusak dikenal dengan lahan kritis. Upaya pengendalian lahan kritis dapat dilakukan melalui kegiatan Rehabilitasi Hutan dan Lahan (RHL) dengan penanaman jenis Multi Purpose Tree Species (MPTS) yang memiliki nilai ekologis dan ekonomis, seperti alpukat (Persea americana) dan petai (Parkia speciosa). Penelitian ini bertujuan untuk mengevaluasi kesesuaian lahan bagi pengembangan alpukat dan petai di Desa Cipicung, Kecamatan Jatigede, Kabupaten Sumedang, Jawa Barat. Metode penelitian menggunakan purposive sampling dengan intensitas sampling 5% pada lima plot untuk masing-masing jenis tanaman. Analisis kesesuaian lahan dilakukan menggunakan metode matching dan scoring terhadap delapan parameter, yaitu temperatur, curah hujan, kelembapan, tekstur tanah, permeabilitas tanah, pH tanah, kemiringan lereng, dan bahaya erosi. Hasil penelitian menunjukkan bahwa kelas kesesuaian lahan aktual untuk tanaman alpukat dan petai pada lahan RHL Desa Cipicung termasuk dalam kategori cukup sesuai (S2) dengan nilai rata-rata skor masing-masing 21,8 dan 24,2. Faktor pembatas utama meliputi temperatur, curah hujan, permeabilitas tanah, kemiringan lereng, dan bahaya erosi. Upaya peningkatan kesesuaian lahan secara potensial dapat dilakukan melalui penerapan teknik konservasi tanah dan air secara mekanik dan vegetatif yang tepat untuk mendukung keberhasilan rehabilitasi hutan secara berkelanjutan.

Abstract

The forest area that plays a role in conservation efforts in Sumedang is the Gunung Palasari Grand Forest Park (TAHURA). These efforts can fail with various threats such as deforestation, exploitation and even economic pressure on the community that puts the condition of the area in a critical situation. The stages of prevention of this threat involve collaboration from various parties, such as academics, the community, and various other stakeholders. The purpose of this study is to invite the community and its surroundings to know the role of trees and want to play a role in planting trees for environmental conservation and developing the community's economy. The academics who contributed were the Faculty of Forestry, Winaya Mukti University, who took an approach through the seminar lecture method. The seminar was held on November 29, 2024 from 08.00 - 16.00 at TAHURA Gunung Palasari which was divided into three sessions, namely material presentation, discussion and tree planting. The material presented was targeted to gain community knowledge about plants, especially trees and their benefits, as well as public awareness to understand the importance of planting trees. This activity was declared successful in achieving its target based on the N-gain test, which obtained 60% from the difference in each pre-test to post-test parameter. The suggestion from this research is that routine planting activities should continue to be carried out.
