Abstract

Masyarakat yang tinggal disekitar hutan memiliki potensi yang besar dalam memanfaatkan hutan, memaknai hutan beserta fungsinya untuk pemenuhan kebutuhan hidupnya. Dusun Promasan merupakan Dusun terakhir di Lereng Gunung Ungaran yang terletak di Desa Ngesrepbalong, Kecamatan Limbangan, Kabupaten Kendal, Jawa Tengah. Dusun Promasan dikelilingi oleh kebun teh dengan latar belakang Gunung Ungaran dan hamparan hutan. Penelitian ini bertujuan untuk mengetahui pemaknaan masyarakat Dusun Promasan tentang fungsi ekologis hutan dan untuk mengetahui cara masyarakat Dusun Promasan memaknai hutan menurut sudut pandang masyarakatnya. Metode penelitian yang digunakan adalah observasi, wawancara dan pengumpulan data sekunder. Analisis data dilakukan secara deskriptif kualitatif. Hasil penelitian ini menunjukkan bahwa masyarakat Dusun Promasan memaknai hutan berdasarkan fungsi ekologis namun tanpa adanya pengelolaan hutan. Berdasarkan hasil penelitian dapat disimpulkan bahwa masyarakat Dusun Promasan memiliki pengetahuan tentang sains yang masih rendah sehingga masyarakat dalam memaknai hutan hanya berlandaskan pada pengalaman masyarakat dalam memanfaatkan hutan untuk kebutuhan hidup sehari-sehari.

Abstract

Bioflocculation is a harvesting technique that employs flocculant agents such as bacteria and microalgae. The benefit is the absence of a chemical-added flocculant. Because bacteria need a particular medium, microalgae flocculant agents are more effective. This study used Anabaena sp. to collect fat, protein, and carbohydrates from the Glagah consortium. Three replications of those microalgae were grown in 300 ml of Bold Basal Medium culture for eight days. On the day of harvest, flocculant microalgae (Anabaena sp.) and non-flocculant microalgae (Glagah) were combined to accomplish flocculation. On the day of harvest, parameters were observed by combining Anabaena sp. with the Glagah consortium in the ratios 1: 1, 0.5: 1, and 0.25: 1. There were three times of each parameter test. Utilizing a wavelength of 750 nm, the proportion of precipitation was calculated spectrophotometrically. Bligh and Dyer were used to measure the lipids. The phenol sulfate technique was used to calculate the amount of carbohydrates. By employing the Bradford method, proteins were quantified. Biofocculation percentages and carbohydrate content were optimum on a ratio of 0.25:1. Lipid and protein content were optimum on a ratio of 1:1.
