Abstract

ABSTRACT Research on the introduction of medang wood is still limited, so it encourages to carry out research on types of medang wood such as the type of lemongrass medang wood which is a type of commercial wood from Jambi Province. One of the properties of wood that can be a reference in identifying lemongrass medang wood is the physical properties of wood based on the position of the trunk (base, middle and tip). This activity of identifying lemongrass medang wood will make it easier to identify the type of lemongrass medang wood with other types of medang wood. In addition, it will simplify the process of work and the purpose of using this type of wood. In connection with the above, this study was conducted which aimed to determine the physical properties of lemongrass medang wood in the position of the trunk (base, middle and end) and the heartwood and qubal. The physical properties of wood for fresh moisture content in heartwood at the base have the highest value of 84.43%, but have the lowest density and specific gravity values of 0.62 g / cm3 and 0.55. Based on the position of the wood in the trunk, the wood at the base has the lowest volume development and depreciation values of 9.75% and 10.50%. Timber at the end position has the highest development and depreciation values of 11.81% and 11.94%. The position of the wood on the trunk has an influence on fresh moisture content and volume development but does not affect the type of wood.   Keywords: heartwood, medang wood, physical properties, position of the trunk, sapwood   ABSTRAK Penelitian mengenai pengenalan kayu medang masih terbatas, sehingga mendorong untuk melaksanakan penelitian mengenai jenis kayu medang seperti jenis kayu medang sereh yang merupakan jenis kayu komersial dari Provinsi Jambi.

Abstract There is recently an issue; Batanghari watershed degradation and sustaining Batanghari watershed quality in Jambi Province, Indonesia. Watershed degradation and sustaining watershed quality as well as putting ecological point of view upon watershed management, which in turn emerge in term : integrated watershed management, is also a global issue. We aware of the interdependency between land and soil along with all inherent aspects in them and watershed quality and all inherent aspects in it. It has been proved that unwise measures upon land and soil gives undesired impacts on watershed quality. The first damages shall mostly be upon water quality. For the existence of human being and livelihood of most communities depend strongly on soil and water, at least true to happen in developing and under developed countries, it is true then that both soil and water should be regarded as very important natural resources. By this thought managing and sustaining watersheds need an integrated measures for both components: river, landuse-soil through an ecological approach, conditio sine qua none all efforts will end in failure. The main goal of watershed management are to integrate the use of water, soil, forest and other natural resources within watershed into a NOT CONFLICTING dynamic-ecological based management. This goal can be achieved through an implementation of interdependency concept to regional space planning.   Keywords: watershed, river and interdependency   Abstrak Baru-baru ini ada masalah; Degradasi DAS Batanghari dan  Menjaga Kualitas DAS Batanghari di Provinsi Jambi, Indonesia. Degradasi DAS dan mempertahankan kualitas DAS serta menempatkan sudut pandang ekologi pada pengelolaan DAS, yang pada gilirannya muncul dalam istilah: pengelolaan DAS terpadu, juga merupakan isu global. Kami menyadari adanya saling ketergantungan antara tanah dan tanah beserta segala aspek yang melekat di dalamnya dan kualitas DAS serta segala aspek yang melekat di dalamnya. Terbukti bahwa tindakan yang tidak bijaksana terhadap tanah dan tanah memberikan dampak yang tidak diinginkan pada kualitas DAS. Kerusakan pertama sebagian besar terjadi pada kualitas air. Karena keberadaan manusia dan mata pencaharian sebagian besar masyarakat sangat bergantung pada tanah dan air, setidaknya benar terjadi di negara berkembang dan terbelakang, maka benar bahwa tanah dan air harus dianggap sebagai sumber daya alam yang sangat penting. Dengan pemikiran tersebut pengelolaan dan pelestarian DAS memerlukan langkah-langkah yang terintegrasi dari kedua komponen: sungai, tata guna lahan-tanah melalui pendekatan ekologis, conditio sine qua none semua upaya akan berakhir dengan kegagalan. Tujuan utama pengelolaan DAS adalah mengintegrasikan pemanfaatan air, tanah, hutan dan sumber daya alam lainnya di dalam DAS ke dalam suatu pengelolaan berbasis ekologis dinamis yang TIDAK BERKONFLIK. Tujuan ini dapat dicapai melalui implementasi konsep interdependensi dalam perencanaan ruang wilayah.   Kata kunci: DAS, sungai dan interdependensi

Abstract

ABSTRACT Gunung Tujuh Lake is located in the Kerinci Sebelat National Park (TNKS) area and is a caldera lake formed by past volcanic eruptions with an altitude of ± 1,996 meters above sea level. The uniqueness of Lake Gunung Tujuh is that it is one of the highest lakes in Southeast Asia. According to Law Number 23 of 1997 concerning Environmental Management, the carrying capacity of a tourist area is a certain ability of an area to receive tourists. The capability of the area is the ability of the maximum number of tourists to utilize the area so as not to cause damage or decrease in the quality of the environment. To find out the maximum threshold for the number of visitors, that is by calculating the Real Carrying Capacity (RCC) as well as the Effective Carrying Capacity (ECC). The purpose of this study was to determine the carrying capacity of ecotourism hiking trails on the Gunung Tujuh lake by calculating the capacity of people who can visit a tourist area effectively. The analysis of the data used in the research on the carrying capacity of Gunung Tujuh tourism is a qualitative method. to determine the maximum number of visits to an area which is based on physical conditions and management conditions in the area, considering three main levels namely: physical carrying capacity (Physical Carrying Capacity/PCC), real carrying capacity (Real Carrying Capacity/RCC) and carrying capacity-effective support (Effective Carrying Capacity/ECC). The results of the research on the carrying capacity of the Gunung Tujuh hiking trails show that the carrying capacity of tourism for visitors who can travel while still obtaining satisfaction with a PCC value of 240 people/day. The RCC value is 233 people per day. The ECC value is 177 people/day. Where the real capacity value has not exceeded the carrying capacity, it is still a small scale for ecotourism carrying capacity. Keywords :  Capacity, Carrying,  Ecotourisme, Gunun, Tujuh    ABSTRAK Danau Gunung Tujuh terletak pada wilayah Taman Nasional Kerinci Sebelat (TNKS) dan merupakan danau kaldera yang terbentuk akibat letusan gunung berapi dimasa lampau dengan ketinggian ± 1.996 mdpl. Keunikan dari Danau Gunung Tujuh merupakan salah satu danau tertinggi di Asia Tenggara.  Menurut Undang-Undang Nomor 23 Tahun 1997 tentang Pengelolaan Lingkungan Hidup bahwa daya dukung kawasan wisata merupakan kemampuan tertentu suatu kawasan untuk menerima wisatawan. Kemampuan kawasan tersebut merupakan kemampuan jumlah maksimal wisatawan dalam memanfaatkan kawasan sehingga tidak menimbulkan kerusakan atau penurunan kualitas lingkungannya. Untuk mengetahui ambang batas maksimum jumlah pengunjung yaitu dengan menghitung Daya dukung Riil (Real Carrying Capacity/RCC) maupupun Daya Dukung Efektif (Effective Carrying Capacity/ECC). Tujuan dilakukan penelitian ini adalah untuk mengetahui daya dukung ekowisata jalur pendakian danau Gunung Tujuh dengan mengitung berapa kapasitas orang yang dapat mengunjungi suatu areal wisata tersebut secara efektif. Analisis data yang di gunakan dalam penelitian daya dukung wisata Gunung Tujuh adalah metode kualitatif. untuk menetapkan jumlah kunjungan maksimum suatu area dimana didasarkan pada kondisi fisik dan kondisi-kondisi manajemen pada area, mempertimbangkan tiga tingkatan utama yaitu: daya-dukung fisik (Physical Carrying Capacity/PCC), daya dukung riil (Real Carrying Capacity/RCC) dan daya-dukung efektif (Effevtive Carrying Capac-ity/ECC). Hasil penelitian daya dukung jalur pendakian Gunung Tujuh bahwa daya dukung wisata untuk pengunjung yang dapat melakukan wisata dengan tetap memperoleh kepuasan nilai PCC sebesar 240 orang /hari. Adapun nilai RCC sebesar 233 orang /hari. Untuk nilai ECC yaitu sebesar 177 orang/hari. Dimana nilai daya rill belum melampaui kapasitas dayadukung masih skala kecil untuk daya dukung ekowisata.

Abstract

ABSTRACT Bamboo can be used as an alternative raw material to replace wood. Bamboo is a fast-growing plant that requires quality improvement. One type of bamboo that has not been utilized optimally is sembilang bamboo. Quality improvement can be done through heat modification. Heat treatment can improve the mechanical properties of a material but can cause discoloration. This study aimed to determine the effect of heat treatment on the discoloration of sembilang bamboo. This research was conducted by giving sembilang bamboo heat treatment at 180°C for 3 hours and 6 hours. The results obtained were sembilang bamboo, after heat treatment for 3 hours and 6 hours became darker than the control. The longer the heating time, the greater the value of the color change.   Keywords: color change, heat treatment, sembilang bamboo   ABSTRAK Bambu dapat dijadikan sebagai bahan baku alternatif pengganti kayu. Bambu termasuk tanaman cepat tumbuh yang memerlukan peningkatan kualitas. Salah satu jenis bambu yang belum dimanfaatkan secara optimal adalah bambu sembilang. Peningkatan kualitas dapat dilakukan dengan cara modifikasi panas. Perlakuan panas dapat meningkatkan sifat mekanis suatu bahan namun dapat menyebabkan perubahan warna. Tujuan penelitian ini adalah mengetahui efek perlakuan panas terhadap perubahan warna bambu sembilang. Penelitian ini dilakukan dengan memberikan perlakuan panas pada bambu sembilang dengan suhu 180°C selama 3 jam dan 6 jam. Hasil yang didapatkan adalah bambu sembilang setelah perlakuan panas selama 3 jam dan 6 jam menjadi lebih gelap dibandingkan kontrolnya. Semakin lama waktu pemanasan maka nilai perubahan warnanya semakin besar.   Kata kunci: bambu sembilang, perlakuan panas, perubahan warna
