Keanekaragaman dan distribusi spasial bambu menggunakan sistem informasi geografis di Ekowisata Boonpring Kabupaten Malang
No full textINDONESIA :
Keanekaragaman dan distribusi spasial memiliki nilai penting sebagai parameter stabilitas suatu ekosistem. Ekowisata Boonpring Kabupaten Malang dominan dengan tumbuhan bambu yang secara ekologi memiliki peran dalam konservasi terutama tanah dan air. Tujuan penelitian ini adalah untuk mengetahui keanekaragaman dan pola sebaran bambu di Ekowisata Boonpring Malang. Penelitian dilakukan di Ekowisata Boonpring Malang pada bulan September-November 2018. Jenis penelitian yang digunakan bersifat deskriptif kuantitatif. Pengamatan ini menggunakan metode petak 20m x 20m sebanyak 50 plot. Parameter yang diukur adalah keanekaragaman dan distribusi spasial yang meliputi indeks keanekaragaman, indeks nilai penting dan indeks morisita. Proses identifikasi dilakukan dengan pencandraan dan pencocokan dengan literatur. Proses pemetaan dan digitasi dilakukan dengan penandaan koordinat lalu diolah menggunakan aplikasi Quantum GIS. Hasil penelitian menemukan jenis bambu yang terdapat di Ekowisata Boonpring Malang terdiri dari 5 spesies antara lain Bambusa vulgaris, Bambusa blumeana, Gigantochloa atter, Gigantochloa apus dan Dendrocalamus asper. Indeks keanekaragaman (H’) didapatkan 0,886 menunjukkan bahwa keanekaragaman bambu di kawasan tersebut tergolong rendah. Indeks Nilai Penting (INP) bambu didapatkan nilai tertinggi pada spesies Gigantochloa atter sebesar 205,074%, sedangkan nilai INP terendah pada spesies Bambusa blumeana sebesar 1,517%. Berdasarkan Indeks Morisita bambu didapatkan bahwa spesies Bambusa vulgaris, Gigantochloa atter, Dendrocalamus asper, Gigantochloa apus mempunyai pola sebaran mengelompok, sedangkan Bambusa blumeana mempunyai pola sebaran acak. Didukung dari hasil peta yang menunjukkan bahwa spesies bambu yang banyak ditemukan adalah Gigantochloa atter dan pola persebarannya paling luas daripada spesies lain. Berdasarkan hasil penandaan koordinat menunjukkan bahwa beberapa jenis bambu terletak antara 112.46447 E, 8.09396 S sampai 112.45862 E, 8.09397 S. Faktor lingkungan di Ekowisata Boonpring Malang adalah suhu 27,5-30,1°C, intesitas cahaya 15.500-18.100 lux, pH 6,5-7, kecepatan angin 0,5-0,9m/s, ketinggian 596-628 mdpl.

Diversity and spatial distribution have important values as parameters for the stability of an ecosystem. Ecotourism Boonpring Malang Regency is dominant with bamboo plants which ecologically have a role in conservation especially soil and water. The purpose of this study was to determine the diversity and pattern of bamboo distribution in Ecotourism Boonpring Malang. The study was conducted at Boonpring Malang Ecotourism in September-November 2018. The type of research used was descriptive quantitative. This observation uses 20m x 20m pond method as much as 50 plots. The parameters measured are diversity and spatial distribution which includes diversity index, important value index and morisita index. The identification process is carried out by recording and matching with the literature. The mapping and digitizing process is carried out by tagging coordinates and then processed using the Quantum GIS application. The results of the study found that the types of bamboo found in Ecotourism Boonpring Malang consisted of 5 species including Bambusa vulgaris, Bambusa blumeana, Gigantochloa atter, Gigantochloa apus and Dendrocalamus asper. Diversity index (H ') was found to be 0.886 indicating that the diversity of bamboo in the area is relatively low. Bamboo's Important Value Index (INP) obtained the highest value in Gigantochloa atter species of 205.074%, while the lowest INP value in Bambusa blumeana species was 1.517%. Based on the Morisita bamboo index, it was found that the species Bambusa vulgaris, Gigantochloa atter, Dendrocalamus asper, Gigantochloa apus had a clustered distribution pattern, while Bambusa blumeana had a random distribution pattern. Supported from map results showing that the most common bamboo species is Gigantochloa atter and the most widespread pattern of distribution than other species. Based on the result of the coordinate tagging shows that some types of bamboo are between 112.46447 E, 8.09396 S to 112.45862 E, 8.09397 S. Environmental factors in Boonpring Malang Ecotourism are temperatures 27.5-30.1 ° C, light intensity 15,500-18,100 lux, pH 6.5-7, wind speed 0.5-0.9m / s, altitude 596-628 masl
Exploration of Local Durian (Durio zibethinus Murr.) from Semen Sub- District, Kediri, East Java Based on Morphological Character and Geograpical Factor
No full textThe purpose of this study is to identify morphological characters and determine the local durian distribution map in Semen District, Kediri Regency. This study uses a purposive sampling method to collect data. Local durian coordinates analyzed using QGIS version 3.6 software. Morphological character is examined by observing morphology. Micro climate factors measured are height, intensity, temperature and humidity of the soil and air, soil pH. The results show that local durin morphology in Semen District Kediri Regency has diversity. There are 10 local durian plants found based on their geographical character. The dendogram results show that local durian has similarities based on its morphological character. This morphological variation dependent to light intensity, altitudinal, the velocity of wind and soil nutrient factors
Spatial Distribution and Morphology Character of Podang Mangoes (Mangifera indica L.) from Five Sub-district in Kediri Regency, East Java, Indonesia
No full textThis study obejctives to determine the distribution maps and identify the morphological character of local Mangga Podang at five sub-districts in Kediri. This research used purposive sampling method for collecting data. Coordinate of local mango wasanalyzed using QGIS software version 3.6. Morphological characters are examined by observing the morphology. Microclimate factors that were measured are altitude, intensity, temperature and moisture of soil and air, soil pH, and soil nutrient. Morphological characterswere analyzed for homogenity by statistical test. The results showed that Mangga Podang distribution has spread in residential areas and has different altitude factors between 85-459 meters above sea level. The total population(individu/400m2) found in this study were Mojo10(11.2%), Banyakan 17 (19.1%), Grogol8 (9%), Semen 3 (3,4%)and Tarokan51 (57.3%). Mangga Podangof Kediri Regency generally have homogenous morphological characters, but there were the special character which differs each other, they are the number of flowers in 1 panicle, the weight of ripe fruit and exocarp color of ripe fruits. This morphological variation dependent to light intensity, altitudinal, the velocity of wind and soil nutrient factors
