Abstract

Fulan Fehan Nature Tourism Area is managed by the Technical Implementation Unit of the Forest Management Unit of Belu Regency. The management of Fulan Fehan Nature Tourism has great functions and benefits for the people of Dirun Village so that it is hoped that the community will continue to maintain and preserve the Fulan Fehan Nature Tourism location. However, the problem is that there is no information and data regarding the community's perception of the management of the nature tourism area so that community perception is important to study because in the perception process, individuals are required to provide positive, negative, and so on. This study aims to determine the characteristics of the Dirun Village community and analyze the perceptions of the Dirun Village community in the management of the Fulan Fehan Nature Tourism area. The data collection technique was carried out using a questionnaire that had been prepared according to the objectives and the analysis used was percentage analysis and a Likert scale. The results of the study showedRespondent characteristics based on gender are dominated by menwhich is 62% or 54 respondents. Respondents based on age are dominated by people aged 17-40 years (early adulthood). The last education of respondents is dominated by high school education as much as 34% or 30 respondents. Based on their occupation, respondents are dominated by farmers, namely 24% or 21 respondents. The average recapitulation of community perceptions of natural tourism management in Fulan Fehan is 2.70, meaning that the people of Dirun Village consider the existence of the area to be good and have a positive impact on the community.

Abstract

The demand for commercial timber in Indonesian continue to increase, while the potential of production forests is decreasing. Therefore, an optimal forest management strategy is needed as a source of raw timber materials, including using quality plant types with fast-growing riaps. One of the potential species is (Cassia fistula L). or Trengguli which is widely found in the province of East Nusa Tenggara, especially Kupang City. However, information about the physical properties of Trengguli limited wood. The research purposes whose physical properties are determined and macroscopic characteristics of Trengguli wood at the base, middle, and end. Physical tested include moisture content, specific gravity, shrinkage, thickness expansion, and water absorption. Samples were taken from the field and tested in the laboratory using the Complete Random Design (RAL) method and analyzed using ANOVA. The results showed an average moisture content of 46%, specific gravity of 0.83, tangential shrinkage of 5.3-6.9%, radial 2.9-4.9%, and longitudinal 0.4-0,5%. Thick development after 2 hours ranges from 0.4-0.6% and after 24 hours 0.5-0.9%. Water absorption after 2 hours ranges from 0.7-1.6% and after 24 hours 1.4-2.7%. Based on ANOVA analysis, the position of the axial wood no real effect on physical properties. This study provides important information about the characteristics of Trengguli wood to support its use as a raw material for commercial wood. Keywords: Trengguli, macroscopic characteristics, physical properties, axial position, wood utilization.

Abstract

Cajuput oil plays a pivotal role in the production of various products, particularly essential oils. This growing demand has led to increased exploitation of woody plants, raising concerns about the sustainability of raw material supply. To support the cajuput oil industry, silvicultural interventions such as optimizing planting techniques are essential. The optimal growth of cajuput seedlings is a critical factor in ensuring successful cultivation and consistent production. One alternative to enhance seedling growth is the use of kasgot (maggot residue) as a weaning medium. Kasgot, a by-product of the black soldier fly (Hermetia illucens) larval digestion process, has been recognized for its potential to improve soil and growing media fertility. This study aimed to determine the most effective dosage of kasgot for promoting the growth of Melaleuca cajuputi seedlings. The research was conducted over a two month (January"“March 2025) at the Forestry Nursery of the Kupang State Agricultural Polytechnic. A completely randomized design (CRD) was employed, with five treatment compositions of weaning media: MK0 (soil:sand = 1:1), MK1 (soil:sand:kasgot = 1:1:1), MK2 (1:1:2), MK3 (1:1:3), and MK4 (1:1:4). Each treatment was replicated three times. The results demonstrated that the MK1 treatment (1:1:1 ratio of soil, sand, and kasgot) was the most effective in supporting the growth of cajuput seedlings. Keywords: cajuput, growth, seedling, weaning medium. Abstrak Minyak kayu putih memiliki peran penting untuk mendukung berbagai macam produk, terutama minyak atsiri. Hal ini berpengaruh terhadap lonjakan ekspoitasi tanaman kayu yang dikhawatirkan akan berdampak pada terbatasnya suplai produk. Upaya silvikultur yang dapat dilakukan untuk industri minyak kayu putih adalah optimalisasi kegiatan penanaman. Pertumbuhan yang optimal dari semai kayu putih sangat penting untuk memastikan keberhasilan budidaya dan produksi. Penggunaan kasgot sebagai media sapih merupakan salah satu alternatif yang dapat digunakan untuk memaksimalkan pertumbuhan tanaman kayu putih. Kasgot (bekas maggot) adalah sisa proses pencernaan makanan dari belatung maggot lalat tentara hitam (BSF) yang dapat meningkatkan kesuburan tanah dan media tanam. Riset ini bertujuan mengkaji dosis yang efektif dari pemberian kasgot terhadap pertumbuhan semai Melaleuca cajuputi. Riset ini dilakukan selama dua bulan (Januari-Maret 2025) di Persemaian Jurusan Kehutanan, Politeknik Pertanian Negeri Kupang. Riset ini menerapkan rancangan acak lengkap. Perlakuannya adalah media sapih yang terdiri dari komposisi tanah, pasir dan kasgot. MK0: (1:1), MK1: (1:1:1), MK2: (1:1:2), MK3: (1:1:3) dan MK4: (1:1:4), dan diulang sebanyak 3 kali. Hasilnya menginformasikan jika kombinasi media sapih paling efektif untuk pertumbuhan semai kayu putih adalah perlakuan MK1 (tanah + pasir + kasgot) (1:1:1). Kata kunci: kayu putih, pertumbuhan, semai, media sapih

Abstract

Kayu lontar (Borassus flabellifer L.) merupakan salah satu jenis palma yang potensial dimanfaatkan sebagai bahan konstruksi, kerajinan, maupun bioenergi, namun informasi mengenai karakteristik kimiawinya masih terbatas. Penelitian ini bertujuan untuk menganalisis komponen kimia kayu lontar asal Pulau Timor secara kuantitatif. Sampel berupa serbuk kayu ukuran 40–60 mesh dari tiga bagian batang (pangkal, tengah, ujung) kemudian dicampurkan agar mewakili variasi sifat kayu sepanjang batang, kemudian dicampurkan untuk mendapatkan hasil yang lebih merata dan representatif. Pengujian yang dianalisis meliputi kadar air, holoselulosa, alfa selulosa, lignin, zat ekstraktif (air dingin, air panas, etanol-toluena, NaOH 1%), serta pH. Hasil penelitian menunjukkan kandungan kadar air 9,35%, lignin 23,91%, holoselulosa 79%, alfa selulosa 43,57%, serta pH 3,53. Kandungan ekstraktif relatif tinggi, yaitu etanol-toluena 17,62%, larut air panas 8,33%, larut air dingin 6,57%, dan larut NaOH 25,19%. Komposisi ini menunjukkan bahwa kayu lontar memiliki kadar polisakarida struktural yang tinggi serta ekstraktif non-polar dan polar yang berperan dalam meningkatkan ketahanan alami terhadap jamur dan rayap, namun pH asam dapat memengaruhi kestabilan dimensi serta interaksi dengan bahan perekat dan logam. Secara keseluruhan, kayu lontar berpotensi digunakan sebagai bahan bangunan, kerajinan, dan sumber bioenergi, dengan perlakuan pengawetan tambahan untuk meningkatkan durabilitasnya baik di interior maupun eksterior.

Abstract

Teak (Tectona grandis L.f.) is a plant that produces raw materials for the wood industry, which is very popular due to its high quality and selling value. Procurement of teak seeds can be done in two ways: generatively and vegetatively. One problem in cultivating this plant is the inhibition of seed germination due to dormancy. Teak roots experience physical inactivity, namely tough skin. One technique that can be used to break seed dormancy is through chemical treatment. This study aims to determine the concentration of sulfuric acid (H2SO4) and the appropriate soaking time to break the teak seeds dormancy. This research was conducted for two months in the Permanent Nursery of the Department of Forestry, State Agricultural Polytechnic of Kupang, from 15 November 2022 until 15 January 2023. This study used a Completely Randomized Design (CRD) with two factors. The first factor was the concentration of a sulfuric acid solution (control: K0, 75% H2SO4: K1, 80% H2SO4: K2, and 85% H2SO4: K3). The second factor was the soaking time (T1: 45 minutes, T2: 50 minutes, and T3: 55 minutes). The two factors was combined to produce 12 treatment combinations as a whole. Each treatment was repeated three times and used ten seeds, so the total seeds used were 360 seeds. The results showed that there was an interaction between the concentration of sulfuric acid solution (H2SO4) with soaking time length, where the combination of 75% sulfuric acid (H2SO4) concentration and 45 minutes of soaking time gave higher results than other treatments, so it can be said that this combination is better at breaking teak seed dormancy.
