Agarwood (Aquilaria malaccensis Lamk.) are now popular to be exploited by farmers as a healthy drink. This research was done to study the effect of the shape and size of the tea from agarwood leaves on the consumers acceptance and antioxidant content. Agarwood leaves tea made in three forms: whole leave, cutted and fine particle size. Agarwood tea from these three size of shape and size then were evaluated of their hedonic level at 0 day and after 2 months of storaged in room temperatur by 50 panelists. The antioxidant activity was evaluated on methanol extracts from the three kinds ofagarwood leaves tea by using DPPH method after 2 month of storage. The result of the research shows that the froporcle of agarwood leave tea was more liked by panelists followed by the cutted leaves tea and the whole leaves tea had the lowest value of the hedonic score. The same result was found on the agarwood leaves tea that had been storage for 2 months, in the term of aroma, color for aswell as taste. The hedonic score of arom, color and taste of agarwood leaves tea after 2 months of storage till more than 3,00. It showed that the agarwood leaves tea still was accepted by panelists.

Abstract

The objectives of this research were to calculate the amount of retention and penetration scores and to examine the stability of dimension and strength of rubber wood after conserving with boric acid preservative (H3BO3). The method applied in this research was hot and cold soaking . After a test sample was preserved with boric acid, then its retention, penetration, and ASE scores were calculated, and the examination of MOE and MOR was conducted eventually. In this research, the best concentrate was gained at treated concentrate 3 % for the retention score, penetration and ASE scores are 1.39 kg/m2, 0.89 mm, and 2.65 %. While the highest MOE and MOR score was gained at 0% concentrate (controlled) with 17619 kg/m2 and 210 kg/m2. The retention and penetration scores increased as the concentrate increased. But the distribution the preservative was able to decrease the strength of wood. Keywords : preservation, rubber wood, boric Acid, MOE, MOR

Abstract

The communities who live around Sibolangit Tourism Park have developed nontimber forest products (NTFP) in their own agroforestry lands. This research evaluates the potential economic and development prospects from NTFP development in the Park by examining: (1) type of NTFP and economic value from community agrofrestry land, (2) contribution of NTFPs on household income, (3) development prospects of NTFP-based agroforestry around Sibolangit Tourism Park. The research was conducted in two selected villages around Sibolangit Tourism Park: Sembahe Village and Batu Mbelin Village. The research took place over a period between June and August 2016. Research data was obtained from in-depth interviews and observations. A descriptive method was used to analyze and describe facts related to the research aims. The type of NTFPs cultivated by communities at the research sites include mangosteen, durian, garcinia, candlenut, lanzones, lansium, bitter bean, and areca nut (as their forestry component) and ginger, turmeric, chili, papaya, etlingera, and banana (as the agriculture component). Most NTFPs are cultivated as a comercial product. The economic value of NTFPs in Batu Mbelin Village has reached Rp. 547,275,000/year or contribute 80.07% of total family income. Meanwhile, the economic value of NTFPs in Sembahe Village has reached Rp 682,100,000/year, contributing to 78.75% of total household income.  Therefore, the prospects for supporting and expanding NTFP in agroforestry plots in and around Sibolangit Tourism Park has high potential for supporting household income

Abstract

Hutan mangrove merupakan salah satu ekosistem pesisir yang paling penting dan bernilai, merupakan areal hutan yang berhubungan langsung dengan lautan yang mempunyai fungsi ekologi, sosial ekonomi, dan fisik. Menurunnya kualitas dan kuantitas hutan mangrove telah mengakibatkan kerusakan lingkungan. Kondisi hutan mangrove Desa Lubuk Kertang, Kecamatan Brandan Barat, Kabupaten Langkat, Sumatera Utara pada saat ini mengalami kerusakan akibat kegiatan illegal logging yang terjadi pada tahun 2023. Tujuan kegiatan PPM yang dilakukan adalah mengedukasi masyarakat tentang rehabilitasi hutan mangrove dan pemberdayaan Kelompok Tani Hutan (KTH). Metode kegiatan meliputi edukasi melalui pemaparan materi, tanya jawab dan diskusi serta pemberian kuisioner kepada peserta yang dihadiri oleh 18 orang.  Hasil kegiatan dari kuisionor menunjukkan bahwa anggota KTH merasa perlu dan butuh untuk merehabilitasi hutan mangrove pasca adanya kegiatan illegal logging. Anggota KTH juga bersedia untuk aktif kembali mengelola kawasan hutan yang rusak melalui kegiatan rehabilitasi.  Anggota KTH juga berharap bisa melakukan kegiatan yang dari kegiatan tersebut nantinya berdaya secara ekonomi, tentunya kegiatan tersebut membutuhkan pendampingan dan keterlibatan berbagai pihak. Pihak Universitas dalam hal ini Universitas Sumatera Utara mengambil peran turut serta dalam kegiatan pendampingan dan rehabilitasi tersebut. Kegiatan rehabilitasi yang dilakukan adalah melakukan penanaman pada areal hutang mangrove yang rusak, khususnya pada areal yang terbuka karena kayunya habis ditebang.
