Abstract

Diversity of biological resources in primary forest is not only limited to the woody plant species, but also covered by underground plant which has diverse species high diversity. This underground plant as one part of the forest ecosystem is a plant that has potential as a medicine. The study aims to conduct an inventory of underground plant species in Gunung Gede Pangrango National Park West Java Province. The method for inventory used spasial analysis with land management unit and multi stage sampling. The spasial analysis used three categories, first the zonation map, second the soil characterization map and the third altitude map. The LMU consist of 6 areas with total plot number 60. The results showed there are 83 species underground plant consist of 45 family. The family consist of Acanthaceae, Annonaceae, Apiaceae, Apocynaceae, Araceae, Araliaceae, Aspleniaceae, Asteraceae, Balsaminaceae, Begoniaceae, Compositae, Convolvulaceae, Cucurbitaceae, Cyperaceae, Elaeagnaceae, Equisetaceae, Fabaceae, Gesneriaceae, Gramineae, Hypoxidaceae, Lamiaceae, Malvaceae, Marattiaceae, Melastomataceae, Menispermaceae, Moraceae, Musaceae, Myrsinaceae, Oxalidaceae, Passifloraceae, Piperaceae, Plantaginaceae, Polygalaceae, Primulaceae, Rosaceae, Rubiaceae, Sellagineaeeae, Smilaceae, Solanaceae, Symplocaceae, Urticaceae, Verbenaceae, Woodsiaceae, Zingiberaceae.

Abstract

The aim of the study was to obtain a comparison of the durability of sengon (Falcataria moluccana) and sugi wood (Cryptomeria japonica) after preservation with Jati (Tectona grandis) tree bark waste to subterranean termites Coptotermes curvignathus Holmgren attack and to determine the best concentration of wood preservation from Jati extract. Evaluation the durability of wood used the JIS K 1571 2004 standar method. Test parameters in the study were preservative retention, termite mortality and weight loss of the wood test sample. The results showed the highest retention was achieved in Sengon wood of 0.466 kg /m3 and the followed by Sugi wood which was 0.740 kg /m3. The lowest termites mortality value was in non-teated wood of Sengon wood with value 13.091%, and in other sengon wood which treated by extract of Jati bark with concentration of 2%, 4%, 5%, the termites mortality was 100%. Meanwhile in Sugi wood the termites mortality in non-treated wood was 12.576% and other Sugi wood which treated by extract of Jati bark with concentration of 1%, 2%, 3%, 4%, 5% the mortality value reached 100%. The average percentage values of the highest weight loss was 15.483% in non-treated sugi wood, while the lowest weight loss was in sengon wood which was given 5% extract of teak bark with a concentration of only 2.099%. The optimal concentration of Jati tree bark for wood preservation to Sengon wood was on concentration 25, meanwhile in Sugi wood was on concentration 1%.Keywords: Cryptomeria japonica, ekstrak kulit kayu, Falcataria moluccana, preservation, Tectona grandis

Abstract

One of the many traditional medicinial plant species found in West Kalimantan is Laban wood (Vitex pubescens Vahl) which extracts are used to treat diseases. Therefore it is expected that exist in the plant of bioactive compounds. This study aims to determine the bioactive compounds in root extracts of Laban from the ethyl acetate fraction to characterize the single compounds. The methods used was the isolation by chromatography column and identification by Liquid Chromatography Mass Spectroscopy (LCMS), Ultra Violet (UV), Infra Red (IR), Nuclear Magneitc Resonance (NMR) and Heteronuclear Multiple Bond Correlation (HMBC). The results obtained from spectrum data Mass Spectroscopy (MS), UV, IR, HMBC and NMR indicated presence of cicerfuran which is a stilbene derivative compound.

Abstract

Keruing tree (Dipterocarpus spp) produced sap which is used for caulking boats; varnish and paint cure for a particular wound. The research aims to determine the sap production keruing intercepted on several different tree diameter classes. Research carried out in the area of ​​Village Forest at Benua Village Sungai Ambawang Kubu Raya District West Kalimantan Province. Keruing tree is tapped is a type of Keruing Kipas (Dipterocarpus spp) with a diameter of 30-39 cm and a diameter of 40-49 cm. Time of tapping carried out in three times, i.e. morning, noon and evening. Tapping stream forms a V-shaped with a height of 130 cm from the ground with a length of 20 cm, a width of 3 cm with an inclination of 45o flat surface. The results of research show the average amount of sap production of Keruing according to grade level diameter tree is a tree with a diameter of 30-39 cm class produce sap Keruing of 73.1 grams and a tree with a diameter of 40-49 cm class produce sap Keruing of 112.18 grams. The study concluded that the larger the diameter of the Keruing tree will produce the higher sap production. This is due to the greater diameter of the tree, the heartwood of the tree will be greater, and the higher content of Keruing sap contained in the sapwood of trees. Keywords: Dipterocarpus spp, Keruing Kipas, sap, times of tapping, tree diameter

Abstract

 Pikul customary forest has the potential of tengkawang that was abundant and utilized by the community around the forest to fulfill their daily needs. This study aimed to determine community social capital consists of cognitive and structural social capital and the relationship of social capital how to use tengkawang fruit in the Pikul indigenous forest. This study used the concept survey methods, with data collection techniques with interviews used questionnaires and in-depth interviews with key respondents. Respondents in this study were Melayang Hamlet community who used tengkawang fruit intentionally. The magnitude level of social capital used the value interval equation and the relationship of social capital was analyzed of Sperman rating coefficient test. The results showed the cognitive social capital and the structural social capital were both classified as "high". The relationship of social capital which used of tengkawang has a direct and strong relationship, the two elements of Cognitive and structural social capital were very significant and relate with the way how to use tengkawang. The real correlation occurred in the form of a positive correlation that showed the higher level of structural social capital and cognitive social capital formed, which better used of tengkawang fruit in the Pikul customary forest.Keywords: social capital, tengkawang fruit, Pikul costomary forestAbstrakHutan Adat Pikul memiliki potensi tengkawang yang sangat melimpah. Jenis ini dimanfaatkan masyarakat sekitar hutan untuk memenuhi kebutuhan hidup. Penelitian ini bertujuan mengetahui modal sosial masyarakat yang terdiri atas modal sosial kognitif dan struktural dan hubungan modal sosial terhadap pemanfaatan buah tengkawang di hutan Adat Pikul. Penelitian ini menggunakan metode survei, melalui teknik wawancara menggunakan kuesioner dan wawancara mendalam kepada responden kunci. Responden dalam penelitian ini adalah masyarakat Dusun Melayang yang memanfaatkan buah tengkawang. Tingkat modal sosial masyarakat dianalisis menggunakan persamaan selang nilai. Sementara itu hubungan modal sosial dianalisis menggunakan uji koefisien Peringkat Sperman. Hasil penelitian menunjukan bahwa modal sosial kognitif serta modal sosial struktural tergolong “tinggi”. Hubungan modal sosial terhadap pemanfaatan tengkawang memiliki hubungan yang searah dan kuat. Kedua unsur modal sosial Kognitif dan struktural berhubungan sangat nyata terhadap pemanfaatan tengkawang. Korelasi nyata yang terjadi berupa korelasi positif yang menunjukkan semakin tinggi tingkat modal sosial struktural dan modal sosial kognitif yang terbentuk, semakin baik pula pemanfaatan buah tengkawang di hutan Adat Pikul.

Abstract

As a part of biodiversity, insects should be conserved. Some insects are beneficial for human life. Ecologically, insects maintain the ecosystem balance and enrich natural resources. Tinjomoyo Forest in Semarang Municipality plays a role as the ecotourism area. The aim of the study was to understand the diversity of the insects of Tinjomoyo Forest, Semarang. A transect method has been employed with the transect dimensions of 20 x 20 m, 10 x 10 m, and 5 x 5 m, with three replicates. The insect identification was carried out in the Biology Laboratory, UNNES. Result showed that 19 insects live in Tinjomoyo Forest with the diversity index of 0.04 to 1.20, and this is considered low. Oechopylla smaragdina has the highest Importance Value Index of 11.89%, whereas Tincola bisselliella has the lowest Importance Value Index of 3.18%. Several factors influence the insect diversity, such as the distribution, the habitat selection, the environmental condition, the vegetation, and the food availability. Keywords: Diversity, insect, species, Tinjomoyo
