Abstract

S. javanica K.&V. merupakan komoditi kehutanan penting penghasil damar yang berasal dari Krui, Lampung Barat. Sampai saat ini diketahui bahwa tegakan tanaman ini yang terbesar dan terluas terdapat di daerah tersebut. Namun, penggembangan lebih lanjut tanaman ini tidaklah mudah karena musim berbuahnya yang tidak teratur dan sifat bijinya yang rekalsitran. Biji rekalsitran bersifat mudah rusak dan tidak tahan lama bila disimpan. Oleh sebab itu dibutuhkan suatu usaha agar umur benih tanaman S. javanica dapat diperpanjang. Penggunaan media simpan merupakan salah satu cara untuk memperpanjang umur benih. Serbuk gergaji dan abu gosok merupakanjenis media simpan yang telah cukup banyak diujicobakan pada beberapa jenis Dipterocarpaceae. Penelitian ini menggunakan rancangan acak lengkap (RAL) yang disusun secara faktorial dengan tiga jenis media simpan (tanpa media simpan, serbuk gergaji dan abu gosok) dengan tiga waktu simpan (4 minggu, 6 minggu dan 8 minggu). Hasil pengamatan menunjukkan bahwa abu gosok merupakan media simpan yang paling mampu menjaga kadar air benih, dan lama penyimpanan yang terbaik adalah tidak lebih dari empat minggu.

Abstract

Agarwood has so high value that can trigger an excessive agarwood encroachment in nature; it threatened the agarwood availability. Agarwood cultivation was the right solution to overcome the Agarwood insufficiency. Currently, bioserum has been found to form Agarwood rapidly. It was found by Kusnadi and introduced to the public by BPDASHLWSS (The watershed management and protection forest inquiry). The formation and effectiveness process of bioserum has not been researched yet scientifically. Therefore, this study aimed to determine the success rate of Agarwood formation and the quality of Agarwood with combined injections treatments on tree branches of Aquilariamalaccensis. This research used a complete randomized design with 3 treatments. Each treatment consisted of several vertical injection hole spaces: 5 cm, 10 cm, and 15 cm. The horizontal space for these three treatments was the same, 5 cm.  The result showed that the best vertical range of injection was 10 cm. Therefore, each injection hole would produce separate agarwood chips. A 10-cm vertical range injection also made the rest wood between the injection holes not too wide. This Agarwood was classified into kamedangan class with the average weight of 2 g/chips.

Abstract

Shorea javanica was a high dependent plant to ectomycorrhizal symbiosis, dealing with its growth. In Lampung Province, S.javanica standing stock have been hundreds of years, known as repong damar.  Its threatened by some deforestation, such as forest fire.  This study aimed to analyze the impact of heating on the ability of ectomycorrhizal colonization and analyze the effect of ectomycorrhizal inoculation on the growth of S. javanica.  The experiment arranged by randomized complete design with 5 treatments, which were without inoculum, unheated inoculum, soil inoculums heat to 40oC, 70oC and 100°C for 24 hours. Soil inoculums are taken under S. javanica standing, at Krui, Pesisir Barat District, Lampung Province. The result analyzed by ANOVA and continued with LSD test.  The experiment was conducted for four months.  The results show that colonization ectomycorrhiza still existed up to 100oC and ectomycorrhiza could enhance growth variables, including height, leaves number, leaf area, root length and root dry weight. The best colonization and growth were on 100oC heating. The heat treatments seem killed some fungus.  Only a few fungi could resist and colonize S. javanica roots.  Without any competitors, the resist ectomycorrhizal could develop broadly.

Abstract

Encroachment on forest areas in Indonesia occurs due to various factors mainly related to tenure issues and economic interests. That encroachment occurred in all regions of Indonesia with vary in intensity and amount. Register 47 Way Terusan which has been designated as a KPHP model Way Terusan also being occupied by squatters since the 1990s. The communities within and around the KPHP Way Terusan area has highly dependency on forest resources. The data collection is done in several ways, namely: interviews, literature searches, downloads Landsat satellite imagery and field verification activities. Landsat images Scene: Path 123 and Row 063 for the year 1994, 1999, 2004, 2009 and 2014. Data analysis was conducted using NDVI (Normalized Difference Vegetation Index) and supervised classification. The results of the analysis of land cover in 1994 until 2014 shows the intensity of dynamics of land cover change in the region KPHP Way Terusan. Land cover changes caused as a result of choice of the type of vegetation that has higher economic value. In 2014, the use of cassava cultivation was the highest (55.24%) because of its high economic value, convenient cultivation and market demand. Partnership with agroforestry pattern most likely applied as management strategy policies to accommodate the interests of various stakeholders in KPHP Way Terusan.

Abstract

This research was conducted to study about abundance and diversity of soil and litter mesofauna to the effect of forest cover change that occurred in the Pemerihan Resort, Bukit Barisan Selatan National Park. This research was compiled in a completely randomized design (CRD) and there were four different lands, which were: (1) primary forest, (2) coffee plantation, (3) corn field, and (4) grassland. The observation of mesofauna was taken in soil and litter from four different lands cover. The variable of observation were mesofauna abundance and diversity index, soil chemical properties (pH, organic carbon, total nitrogen, P available, and exchanged potassium), and soil physics properties (bulk density, soil temperature, humidity, and porosity). Data were analyzed using F test and further test using least significant differences (LSD) at 5%. The results showed that the different of lands cover affect the diversity index of litter mesofauna, the abundance of litter and soil mesofauna, yet did not affect the diversity index of mesofauna underground. However, the abundance and diversity index of soil and litter mesofauna in the primary forest was higher than the other lands.
