PENGARUH KOMPOSISI MEDIA TANAM DAN PEMBERIAN DOSIS PUPUK PGPR (Plant Growth Promoting Rhizobacteria) TERHADAP PERTUMBUHAN SEMAI KETIMUNAN (Gyrinops versteegii) CABUTAN
Full text linkTujuan penelitian ini adalah untuk mengetahui pengaruh media tanam dan dosis pupuk Plant Growth Promoting Rhizobacteria (PGPR) terhadap pertumbuhan semai gaharu, serta mengetahui interaksi antara media tanam dan dosis pupuk PGPR. Metode yang digunakan dalam penelitian ini adalah metode eksperimental menggunakan Rancang Acak Lengkap (RAL) yang terdiri dari 2 faktorial. Faktor pertama adalah media tanam yang terdiri dari 4 aras yaitu kompos (P0), kompos+cocopeat perbandingan 1:1 (P1), cocopeat (P2), dan kompos+cocopeat dengan perbandingan 1:2 (P3). Faktor kedua adalah tanpa penggunaan pupak PGPR (F0), dosis pupuk 100 ml (F1), dosis pupuk 200 ml (F2), dosis pupuk 300 ml (F3). Dari kombinasi kedua faktor tersebut dihasilkan 16 perlakuan, setiap kombinasi perlakuan terdiri dari 3 ulangan, dimana pada masing-masing ulangan terdapat 4 tanaman, sehingga mengasilkan 192 sampel penelitian. Parameter yang diamati pada penelitian ini adalah persentase hidup, tinggi tanaman, diameter batang tanaman, jumlah daun tanaman dan kekokohan tanaman. Hasil pengamatan diuji menggunakan analisis sidik ragam pada taraf nyata 1%. Dari hasil pengamatan menunjukkan bahwa media tanam dan pupuk PGPR tidak berpengaruh nyata terhadap parameter yang diamati
SIFAT FISIKA BAMBU PETUNG (Dendrocalamus asper (Schult. f.) Backer ex Heyne) dari KHDTK (Kawasan Hutan Dengan Tujuan Khusus) SENARU BERDASARKAN POSISI AKSIAL
Full text linkThe aims of this study are to determine the influence of bamboo culm section, axial position, and interaction between the culm section and the axial position on physical properties of bamboo petung derived from KHDTK SENARU, North Lombok. The method used in this study was the experimental method using a completely randomized factorial design (CRFD) with two factor. The first factor was the culm section (node and internode) and the second factor was the axial position (bottom, middle and top). Parameters that were observed in this study were green moisture content (MC), air dried MC, green specific gravity, longitudinal and thick shrinkage from green condition to oven dried condition. Data analysis used is the analysis of variance with a confidence level of 95%. The result shows that culm section, the interaction between culm section and axial position did not give significant influence on physical properties. While the axial position which included green MC and green specific gravity has a significant influence on physical properties. A further test was done on a significant result using Tukey's HSD test. Green MC decreases along the culm from base to top. In contrast, green specific gravity increases along the culm from base to top
PERSEPSI WISATAWAN TERHADAP FASILITAS WISATA DI PUSAT LATIHAN GAJAH TAMAN NASIONAL WAY KAMBAS
Full text linkThe growth of tourism is affected by the level of satisfication from the visitors towords the existence of tourism facilities. The aim of this research is to know the visitors perspective towards the tourism facilities at Elephant Training Center of Way Kambas National Park. The data taking can be done by doing interviews, observation and literatures. The collected data will be analyzed descriptively based on physics, cleaniness and comfort condition. The result of research shows that the visitors perception towards the tourism facilities is enough. This is not apart from the condition of facilities that are less well meintained and even damaged, such as toilets, bins, attractions arena and playground; although the qality and quntity is sufficient for the needs of tourist. The national park party needs to add the amount and improve the facilities so it can support the management of the area and improve the amoun of visitors
KEANEKARAGAMAN SPESIES DAN KONTRIBUSI HUTAN MANGROVE TERHADAP PENDAPATAN MASYARAKAT DI DESA EYAT MAYANG KECAMATAN LEMBAR KABUPATEN LOMBOK BARAT
Full text linkDesa Eyat Mayang khususnya Dusun Eyat Mayang Selatan Kecamatan Lembar merupakan salah satu wilayah yang memiliki potensi mangrove. Hal ini tentunya dapat memberikan peluang bagi masyarakat untuk dapat meningkatkan perekonomiannya, dengan cara memaksimalkan fungsi ekologi mangrove tersebut.  Penelitian ini bertujuan untuk mengetahui ragam spesies mangrove, serta ragam kegiatan masyarakat Desa Eyat Mayang Kecamatan Lembar untuk mendukung kelestarian Hutan Mangrove. Berdasarkan informasi pola pemanfaatan Mangrove maka dilakukan pengkajian pendapatan rumah tangga serta kontribusi pendapatan dari aktivitas di hutan mangrove masyarakat di Desa Eyat Mayang. Kecamatan Lembar Penentuan daerah penelitian dilakukan secara purposive sampling dengan dasar pertimbangan bahwa lokasi tersebut merupakan desa dan terdapat masyarakat petani mangrove. Pengumpulan data dilakukan dengan cara observasi di lapangan dan wawancara langsung pada responden yang kemudian dianalisa secara desktiptif. Hasil penelitian menunjukan bahwa terdapat 10 ragam spesies mangrove yaitu Rhizopora Stylosa, Rhizopora Apiculata, Rhizopora Mucronata, Lumnitzera Racemosa, Soneretia Alba, Xylocarpus Moluccensis, Xylocarpus Granatum, Bruguiera Gymnorrhiza, Sonneratia Caseolaris (Buah Pidada), Avicennia Marina (Api-api).  Ragam kegiatan masyarakat dapat digambarkan sebagai berikut pemanfaatan atau penangkapan biota laut di dalam dan di luar hutan mangrove, pembibitan dan penanaman mangrove, perlindungan dan pengamanan, dengan total pendapatan rumah tangga masyarakat dari luar hutan mangrove diperoleh total rata – rata sebesar Rp. 32.997.058,82/tahun/Keluarga, dan pendapatan dari dalam mangrove adalah sebesar Rp. 7.833.529,41/tahun/Keluarga. Berdasarkan hal tersebut diperoleh kontribusi pendapatan dari mangrove adalah sebesar 19.19%
KARAKTERISTIK PAPAN PARTIKEL DARI LIMBAH KULIT KACANG TANAH DENGAN PEREKAT ALAMI ASAM SITRAT DENGAN PELARUT ASAP CAIR
Full text linkBinderlessboard is one of the potential eco friendly products that can be developed. Utiliation of natural adhesives for non-wood composite is still very limited. Therefore, this research is focused on effects of citric acid content and pressing time on characteristics of particleboard made from peanut shell including its durability to dry wood termite attacks. Peanut shell particles were used as raw materials. Citric acid dissolved in liquid smoke which functioned as a water substitute solvent under a certain ratio and the concentration of the solution was adjusted to 60%. The use of liquid smoke is expected to increase the durability of the particleboard. Factors used in this research were citric acid content (10-30% based on dry weight particles) and pressing time (10 minutes and 15 minutes). Properties of particleboard were analyed based on Japanese Industrial Standard (JIS) A 5908 for particleboard. The dry wood termite resistance was then analyzed for its weight loss and mortality after 4 weeks. The results showed that the best particleboard was obtained from the treatment of 30% citric acid content with 15 minutes of pressing time where only the modulus of rupture and modulus of elasticity did not met the requirement of JIS A 5908 type 8 with the thickness swelling were 3.276%, water absorption were 44,991%, internal bonding were 4.679 kgf / cm², modulus of rupture were 26.822 kgf / cm², and modulus of elasticity were 8,986,058 kgf / cm². The best value of weight loss and mortality of dry wood termites on particleboard was obtained in a combination of 30% citric acid content with 10 minutes pressing time were 1.083% and 38.67% respectively
INVENTARISASI POTENSI SUMBER DAYA EKOWISATA DI DANAU WAY JEPARA LAMPUNG TIMUR
Full text linkLake Way Jepara is one of the tourist destinations in East Lampung district that has the potential to be developed. An inventory of potential resources of ecotourism at Lake Way Jepara is done by the method of a survey to analyze and document the ecotourism resources at the site. The result of this research shows that the potential of ecotourism resources reside on the Mainland and in the waters of the Lake, including the potential of the landscape, flora and fauna, amenities and services, accommodation and infrastructure. The Mainland covers landscape view of the street, hallway view arboretum, view of the dam and the beauty of the landscape of the Lake. Resources of flora and fauna include 29 species of trees, 26 wildlife species and 21 species of fish. The available infrastructure includes the main road, the alternative way, path tracking, bridges, parking and irrigation canals. Facilities and services include an Advisory Board, a gazebo, a symbolic monument, the Hall opens and seating. Accommodation available: hotel, camping ground, operational as well as homestay. The spread of ecotourism resources clumped in two zones, so that will make it easier in the planning and development of ecotourism
