Abstract

Makroalga merupakan komponen penting di dalam ekosistem perairan karena berfungsi sebagai produsen yang menentukan kelangsungan hidup dari berbagai organisme perairan. Dengan kata lain, makroalga juga turut berperan dalam produktivitas perairan. Desa Hatu merupakan salah satu Desa yang terletak di Kabupaten Maluku Tengah dengan perairan yang memiliki berbagai sumberdaya perikanan ekonomis. Penelitian ini bertujuan untuk menginventarisir spesies makroalga di perairan pantai Desa Hatu, Kabupaten Maluku Tengah. Metode yang digunakan adalah survey. Hasil penelitian menunjukkan adanya 10 spesies makroalga yang ditemukan di perairan pantai Desa Hatu, Kabupaten Maluku Tengah yang terdiri dari 6 spesies Chlorophyta, 1 spesies Rhodophyta, dan 3 spesies Phaeophyta. Spesies-spesies makroalga yang ditemukan di perairan pantai Desa Hatu, Kabupaten Maluku Tengah, yaitu Cladophora vagabunda, Codium arabicum, C. hubbsii, C. vermilara, Dictyosphaeria cavernosa, Neomeris annulata, Padina australis, Turbinaria conoides, T. ornata, dan Gracillaria gracilis.

Abstract

Penelitian ini bertujuan untuk menentukan hubungan dari Protoreaster nodosus dengan padang lamun di perairan pesisir Tanjung Metiella Pantai Liang, Kabupaten Salahutu Provinsi Maluku Tengah. Layout garis transek diletakkan berdasarkan kehadiran padang lamun. Pada setiap transek, parameter yang diukur meliputi suhu air, ph air, salinitas, dan oksigen terlarut. Pengambilan sampel Protoreaster nodosus dan lamun dilakukan pada transek yang sama , menggunakan metode transek kuadran 1 × 1 m . Dalam studi tersebut ditemukan 5 spesies yaitu Cymodocea rotundata, Cymodocea serrulata , Halodule uninervis, Enhalus acoroides dan Halophila minor. Hasil analisis asosiasi, jenis asosiasi dan derajat asosiasi menunjukkan bahwa Protoreaster nodosus berhubungan secara positif minimum dengan Halodule uninervis dan Enhalus acoroides.This study aimed to determine the association of Protoreaster nodosus with seagrass in the coastal waters of Metiella Cape Beach of Liang Village, districts of Salahutu Central Maluku Province. Layout of the transect line was put based on the presence of seagrass beds in each transect measured parameters include temperature, water ph, salinity, and DO. Protoreaster nodosus and seagrass sampling performed on the same transects, using transect quadrant method 1 × 1 m. In the study found 5 species which is Cymodocea rotundata, Cymodocea serrulata, Halodule uninervis, Enhalus acoroides, and Halophila minor. Results of analysis of an association, the association type, and degree of association showed that Protoreaster nodosus positively minimum associated with Halodule uninervis and Enhalus acoroides.

Abstract

ABSTRACTMelon (Cucumis melo L.) is a high economic value horticultural crop that is cultivated in some regions of Indonesia under fertilization management. Application of inorganic fertilizer continuously can reduce soil microbial abundance. One of the soil microbial that promote plant growth is arbuscular mycorrhizal fungi (AMF) and Azospirillum sp. The aim of this study was to analysed the effect of AMF and Azospirillum sp. in promoting growth and production of melon. The experiment was carried out in a greenhouse and was arranged in a completely randomized design with five replicates. Five treatments tested were: control, fertilized with NPK, inoculated with AMF, inoculated with Azospirillum sp., inoculated with AMF + Azospirillum sp. The results showed that the effect of AMF on root growth and shoot growth were similar to NPK fertilizer. Azospirillum sp. increased root growth. On the other side, the effect of Azospirillum sp. on shoot growth was similar to NPK fertilizer. However, AMF and Azospirillum sp. inoculation solely increased plant height, fruit weight, fruit diameter, flavor and length of fruit storage. Meanwhile, combination of AMF and Azospirillum sp. increased plant height, root growth, shoot growth, fruit weight, fruit diameter, flavor and length of fruit storage. This study revealed that application of AMF and Azospirillum sp. in melon cultivation was more effective and efficient than NPK fertilizer.Keywords: arbuscular mycorrhizal fungi, Azospirillum sp., Cucumis melo L.
