Abstract

The purpose of this research was to know existence and diversity index of Arbuskular Mycorrhiza  Fungi at rhizosfer of kalapi. This research has been done on two growing environment in the Kolaka regency, ie. Pomalaa district and Anaiwoi district, Extraction and spore identification at forestry Laboratory, Faculty of Forestry and Environmental Science., and Soil analyzes at Analytical Chemistry Laboratory, Faculty of Mathematics and Natural Science, Halu Oleo university.  This research was using soil separating method to isolate spore and staining root method to find out root colonization. The observed parameters were type and AMF diversity index.The results showed that (1) the spores of fungi Mycorrhizal Fungi (AMF) associated with the rhizosphere of plants kalapi, where its existence on two different growing environments between natural forests and forest folk Pomalaa Subdistrict Anaiwoi in Kolaka; (2) the main difference of the growing environment kalapi plant area in District Pomalaa and Anaiwoi, namely the condition of vegetation on Pomalaa (Natural Forest) and in Anaiwoi (community forest), altitude Pomalaa (100,97 m dpl) and Anaiwoi (20.25 m dpl ), Pomalaa temperature (27oC) and Anaiwoi (30 °C), humidity Pomalaa 69% and Anaiwoi 64%, the pH of the soil in Pomalaa  6.5 and Anaiwoi 5.4, as well as P-provided Pomalaa 4.45 ppm and Anaiwoi 7, 84 ppm; (3)  The existence of growing FMA in Environmental Natural Forest in District Pomalaa, namely Glomus sp many as six species with 30 Spore, one species Acaulospora sp and one species Gigaspora sp. While in the growing environment of community forests in the district Anaiwoi, namely Glomus sp is nine species with 90 spores, with two spores Acaulospora sp and sp Gigaspora with the spores, each of the species; (4) FMA diversity index in the growing environment in the District Natural Forest Pomalaa lower the 1,547 with low category, compared with the index of diversity on these lands in the District Anaiwoi (1.967) with the medium category. Key word:  Mycorrhiza Fungi, Spore, Growing environment different, diversity index, Kalapi

Abstract

The research of seedling multiplication on local species through the use of shoot cuttings given by Rooton-F PGR in a properly concentration has been implemented as one of the efforts to increase the availability of seedling. This is needed in order to develop a teak forest in the dry areas. The main objective of this study was to determine the properly Rooton-F concentration which showed the best effect on the growth of local teak shoot cuttings in the nursery. The research carried out at the home community nursery and continued in laboratory of forestry, Faculty of Forestry and Environmental Sciences, University of Halu Oleo for three months, from May to July 2015. The research method used completely randomized design (CRD), consists of six concentrate treatments on PGR Rooton-F, namely:  0 ppm as the control (A), 100 ppm (B), 200 ppm (C), 300 ppm (D), 400 ppm (E), 500 ppm (F) and 600 ppm (G).  The each treatment was repeated three times so that there were 18 units of research experiments. Results of the study were measured at the end of the study (46 HST) including: (1) the percentage of cuttings of life, (2) the length of roots, (3) root dry weight, (4) stem dry weight, (5) dry weight of shoots, (6) plant height, (7) and number of leaves. Analysis of the research data to determine the effect of treatment using the F test, while to know the different effects of each treatment used HSD test at the level of 95%. The results showed that Rotoone-F PGR significantly affect the growth of local teak shoot cuttings. The best concentration which gave the best growth in all measured variables was 300 ppm Rooton-F. Thus, propagation techniques in order to increase local teak seedling availability in the dry areas are suggested using shoot cuttings with Rooton-F concentration of 300 ppm. Keywords: Vegetative propagation, shoots cuttings, Rootone-F, Local Teak, Dry Climate

Abstract

Penelitian ini bertujuan untuk mengetahui tingkat kerentanan penghidupan rumah tangga nelayan Bajau akibat variabilitas iklim di Pulau Saponda Kecamatan Soropia Kabupaten Konawe. Penelitian ini dilaksanakan pada April hingga Juni 2019 dengan pengambilan sampel menggunakan teknik simple random. Hasil penelitian menunjukan bahwa masyarakat pada level rumah tangga di kelurahan di Pulau Saponda meyakini bahwa variabilitas iklim telah terjadi, baik di tempat mereka bermukim maupun di wilayah di mana mereka biasanya mencari ikan. Selain itu, warga juga merasakan akibat dari variabilitas iklim dimaksud pada hasil tangkapan laut. Selain itu, masyarakat Bajau merasakan beberapa gejala perubahan suhu, kelembaban dan curah hujan yang tidak menentu maupun pada kejadian bencana gelombang tinggi dan angin kencang. Bencana seperti ini berimplikasi pada kerentanan penghidupan rumah tangga mereka. Berdasarkan penghitungan dengan menggunakan metode LVI-IPCC, skor tingkat kerentanan penghidupan nelayan Bajau di Pulau Saponda adalah 0,109 atau termasuk pada tingkat yang tinggi. Beberapa hal yang mempengaruhinya antara lain tingginya tingkat keterpaparan 0,711 dan sensitivitas 0,508 nelayan tersebut terhadap dampak variabilitas iklim yang tidak dibarengi dengan kapasitas adaptasi yang lebih baik 0,496.
