Abstract

Essential oil is a non-timber forest product commodity that has a high selling value. PT. Wirakarya Sakti (PT. WKS) is one of the owners of an industrial plantation forest (HTI) that plants Eucalyptus pellita F. Muell. The utilization of this tree is only focused on wood for pulp production, so it produces leaf and bark waste. The E. pellita leaves are very potential to produce essential oils that have high selling value. However, the characteristics of essential oil from this E. pellita clones are still unknown. Therefore, it is necessary to analyze the quality of eucalyptus essential oils from these clones. The leaves of E. pellita from clone tree 77, 361, and 364 in PT. WKS was harvested and distilled using the water and steam distillation method to produce the essential oil. After that, the yield of essential, physical and chemical characteristics was analyzed following the Indonesian national standards (SNI 06-3954-2006). The results showed the yield percentage of eucalyptus oil from 3 clone trees are 0.080–0.130%. The results of physical and chemical characteristics of essential oil showed: (1) eucalyptus oil color is yellowish-green, (2) it has a distinctive smell of eucalyptus oil, (3) the specific gravity between 0.900–0.907, (4) 80% solubility in ethanol shows 1:10 turbid, (5) cineole percentage between 39.65–41.13%, and (6) refractive index between 1.462–1.463. The data analysis showed that clone 77 has a higher quality compared to the others.

Abstract

Preserving wood using chemical preservatives has a negative effect on the environment, so preservatives are needed that are more environmentally friendly. Wood vinegar from sawn waste contains potential acid and phenol compounds as natural preservatives. This study aims to assess the effectiveness of tembesu wood vinegar (Fagraea fragrans) and rengas (Gluta renghas) as natural preservatives and analyze the durability of pulai wood (Alstonia scholaris) against Schizophyllum commune Fires. The preservation method is carried out by cold-soaking for 48 hours then proceed with the feeding process with the fungus Schizophyllum commune Fires for 8 weeks. The variables observed were retention value, absorption and penetration of preservatives. The results showed that the retention and absorption value of pulai wood that was soaked with wood vinegar decreased based on the position of the wood part, starting at the base, middle and tip. The value and absorption of tembesu wood vinegar has a greater value than renghas wood vinegar. The results of wood vinegar penetration showed increased values starting from the base, middle, and top of the wood. Renghas wood vinegar is not visible from the penetration result while tembesu wood vinegar is visible from the penetration. The visual checking on the wood samples shows that the both of Renghas and Tembesu wood vinegar can be inhibited the Schizophyllum commune Fires growth.

Abstract

Bungur wood (Lagerstroemia speciosa Pers.) is often used as a construction over ocean waters and is still widely available. Based on (SNI) 01-7210-2006 concerning types of wood for shipbuilding, bungur wood is included in the construction materials for traditional wooden ships, such as: frames, ivory, titles, leather and gladak boards. Bungur wood has low resistance to wood destroying organisms (III-IV), but has a fairly strong resistance to waves and strong winds (I-II). Application of fumigation on wood has long been done to preserve wood. The purpose of the research was to analyze the interaction between smoking duration and the depth of treated wood feed to the marine borer attack. The treatment factors used were the length of smoking time (control (without smoking) 6 hours, 12 hours and 24 hours) and the depth of feeding (two meters and four meters. The tests observed were weight gain after smoking, intensity of marine borer attack and identification of marine borer. After feeding for 6 months the results showed the interaction of smoking duration and feeding depth of bungur (Lagerstroemia speciosa Pers.) significantly affected in reducing the intensity of marine borer attack. The best thing is that smoking for 12 hours at two meters of feed can increase the durability of bungur wood to Durability class II from the intensity of marine borer attack

Abstract

ABSTRACT Wood densification is a wood compaction process that aims to increase the density and strength of wood. The application of the densification method to low-quality wood is expected to provide added value to the wood so that it is used by the community. For example, in the type of pulai wood which is included in the IV–V strong class with an average specific gravity of 0.38 g/cm3. Wood densification is affected by wood plasticity, wood plasticization can be done with a softening technique before the wood is processed through pre-treatment such as steaming. The purpose of this study is to analyze the effect of steaming time on the physical and mechanical properties of densified pulai wood (A. scholaris). This study used a Complete Random Design of one factor of steaming time treatment with 5 levels of experiments, namely no treatment/control, steaming time of 30 minutes, 45 minutes, 60 minutes and 75 minutes. Physical and mechanical properties testing is carried out on test samples that have been densified. Physical property testing including moisture content and density refers to the standards JIS Z 2102 (1957) and JIS Z 2103 (1957). The mechanical properties tested are MOR and MOE referring to the JIS Z 2113 (1963) standard. The results showed that the steaming time had an effect on the value of moisture content, density, modulus of elasticity and modulus of rupture. The steaming 30-minute, 45-minute and 60-minute times provide results that are not noticeably different, but are markedly different from the 75-minute and control steaming times (without steaming).   Keywords: densification, pulai wood, steaming   ABSTRAK Densifikasi kayu merupakan suatu proses pemadatan kayu yang bertujuan untuk meningkatkan kerapatan dan kekuatan kayu. Penerapan metode densifikasi terhadap kayu-kayu berkualitas rendah diharapkan dapat memberikan nilai tambah pada kayu tersebut sehingga ragam penggunaannya oleh masyarakat. Misalnya pada jenis kayu pulai yang termasuk dalam kelas kuat IV–V dengan berat jenis rata-rata 0,38 g/cm3. Densifikasi kayu dipengaruhi oleh plastisitas kayu, plastisisasi kayu dapat dilakukan dengan teknik pelunakan sebelum kayu dikempa melalui perlakuan pendahuluan (pre-treatment) seperti pengukusan. Tujuan penelitian ini adalah menganalisis pengaruh waktu pengukusan terhadap sifat fisis dan mekanis kayu pulai (A. scholaris) yang didensifikasi. Penelitian ini menggunakan Rancangan Acak Lengkap satu faktor perlakuan waktu pengukusan dengan 5 taraf percobaan yaitu tanpa perlakuan/kontrol, waktu pengukusan 30 menit, 45 menit, 60 menit dan 75 menit. Pengujian sifat fisis dan mekanis dilakukan terhadap contoh uji yang telah didensifikasi. Pengujian sifat fisis meliputi kadar air dan kerapatan mengacu pada standar JIS Z 2102 (1957) dan JIS Z 2103 (1957). Sifat mekanis yang diuji adalah MOR dan MOE mengacu pada standar JIS Z 2113 (1963). Hasil penelitian menunjukkan waktu pengukusan memberikan pengaruh pada nilai kadar air, kerapatan, modulus of elasticity dan modulus of rupture. Waktu pengukusan 30, 45 dan 60 menit memberikan hasil yang tidak berbeda nyata, namun berbeda nyata dengan waktu pengukusan 75 menit dan kontrol (tanpa pengukusan).

Abstract

Hasil hutan bukan kayu (HHBK) adalah hasil hutan kecuali kayu seperti produk turunan dari tumbuhan dan hewan beserta budidayanya. Beberapa jenis produk HHBK mempunyai nilai ekonomi yang tinggi di Provinsi Jambi antara lain: rotan, bambu, aren, madu, jernang, gaharu, minyak tengkawang, minyak atsiri, gondorukem, buah-buahan tropis dan lain-lain. Salah satu pemanfaatan HHBK di Kawasan KPHP Unit XIII Muaro Jambi di Desa Jambi Tulo, Kecamatan Maro Sebo, yaitu masyarakatnya memanfaatkan pohon aren yang banyak tumbuh alami, dengan mengolah nira dari pohon aren menjadi gula merah cetak dan dengan pengolahan yang sederhana. Hasil olahan gula merah cetak pada industri rumah tangga masyarakat umumnya masih bermutu rendah karena pengolahan belum dilakukan secara baik, sehingga produk yang dihasilkan cepat meleleh, karena masih mengandung kadar air cukup tinggi 15-17%. Upaya meningkatkan nilai jual gula aren cetak dengan cara mengolah menjadi gula aren granular (gula semut), solusi yang ditawarkan terhadap permasalahan tersebut, diantaranya: diberikannya penyuluhan dan pelatihan kepada masyarakat mengenai pembuatan gula semut dari gula merah cetak secara tradisional dengan menyediakan alat pembuatan gula semut dari gula cetak menjadi bentuk granular (gula semut).

Abstract

Indonesia is one of the countries that has a large enough forest in the world. However, the size of the forest area is not in line with the concept of sustainable forest management. The rate of deforestation in Indonesia inside and outside forest areas from 2015 to 2019 reached 56,865.3 ha/year. This condition results in erratic climate change. One of the forest areas in Indonesia that contributes to these conditions is the Sultan Thaha Syaifuddin Forest Park. The condition of this area experienced a decline in both quality and quantity, especially in 2015. This conservation area had experienced a forest fire disaster that year. Therefore, at this time the condition of burned area is in a period of succession. However, this succession process does not appear to be managed properly. This can be monitored from the emergence of acacia (Acacia mangium) which is quite a lot in the burned area. Even though this location is endemic to iron wood tree (Eusideroxylon zwgeri). One very important way to improve this condition is to emphasize community participation around the forest park itself. This participation can be in the context of safeguarding, securing, preserving, and developing a long-term management plan for the forest park. One of the community participatory concepts that can be applied in conservation forest areas, is edu-ecotourism nature-based tourism. The community services activity has been carried out well for outreach activities as well as focused group discussions/FGDs. For outreach activities, the results showed that there was an increase in public understanding and knowledge about edu-ecotourism-based nature tourism. Then for the FGD activities, it was found that the community supports ecotourism activities that will be carried out, with the hope that the community can be directly involved in the ecotourism activities. The community also expects direct guidance and direction from the Batanghari Regency Environmental Service.
