Abstract

This study aims to determine the phylogenetic position of rotifer Brachionus sp. sample originated from Tumpaan coastal water, North Sulawesi in the phylogenetic tree of Brachionus spp. from 27 samples of rotifer selected from 100 samples available in NCBI Genbank. The phylogeny tree was constructed on the basis of COI (Cytochrome Oxidase I) gene sequences using MEGA7 software and the neighbor-joining method. Results show that the phylogeny tree was divided into 2 clades, the group (closely related group) and out-group (distantly related group). It is confirmed that the position of the rotifer originating from Tumpaan Coastal Water is within in group, which has closely related to the B. plicatilis complex BUS06 indicated by a bootstrap value of 80%. The group belongs to SS-type rotifers with an average body size of 149±1.3 μm. This rotifer group has been known as live prey for fish larvae with a mouth-opening size of 150 μm.

Abstract

Taman Kota merupakan bagian dari ruang terbuka hijau publik. Saat ini ketersediaan taman di Kota Manado telah memenuhi proporsi penyediaan taman kota sebagaimana standar yang berlaku. Namun kenyataannya pemanfataan taman kota masih sepi dari pengunjung dan sepertinya belum memenuhi harapan masyarakat. Tujuan penelitian adalah menganalisis preferensi masyarakat terhadap pemanfaatan taman kota sebagai ruang terbuka hijau publik di Kota Manado. Penelitian menggunakan metode analisis kualitatif deskriptif. Hasil penelitian berdasarkan preferensi masyarakat terhadap pemanfaatan taman kota menunjukkan bahwa taman kota yang paling diminati adalah Manado Godbless Park. Alasannya karena ketersediaan fasilitasnya dan keberagaman aktivitas yang ada lebih representatif jika dibandingkan dengan lapangan Sparta Tikala dan lapangan Sario serta taman kota lainnya di Kota Manado. Preferensi masyarakat terhadap pendukung kualitas fasilitas taman kota, seperti kenyamanan, kebersihan, keindahan, keamanan dan kemudahan akses merupakan hal penting yang perlu mendapat perhatian dari semua pihak.

Abstract

Certain soil-borne diseases can have a detrimental effect on the quality and quantity of peanut production. One of the soil-borne diseases is Sclerotium rolfsii, a fungus that is the primary limiting factor in peanut plants. An alternative to controlling this fungus is to use saprophytic and endophytic fungi. The purpose of this study was to evaluate several saprophytic and endophytic fungi isolated from peanut plants in vitro as antagonistic agents against S. rolfsii. Isolation of saprophytic and endophytic fungi was carried out using the stratified dilution method. The fungal antagonism test was carried out using a non-factorial completely randomized design with 3 replications. The parameters observed in this study included the inhibiting zone, the diameter of the isolate colonies, the growth area, and the interaction of saprophytic and endophytic fungi with S. rolfsii. Five families and eight species of soil fungi were identified using macroscopic and microscopic identification techniques. The type of soil fungus has a large impact on the growth rate and inhibition area. Mucor hiemalis grew at the fastest rate, while Rhizopus oryzae had the largest inhibition zone.

Abstract

This study aims: (1) to determine the effect of crude extract of durian seeds on weed control in oil palm plantations, (2) to determine the effect of the herbicide oxyfluogen 240 g/L which is effective on weed control in oil palm plantations, (3) to determine the effect of interaction of crude extract of durian seeds and oxyfluogen herbicide on weeds in oil palm plantations. The method used in this study was a randomized block design with a factorial pattern. The first factor was durian seed extract (D) with a concentration consisting of 4 levels, namely: control (D0), 100 ml/L (D1), 200 ml/L (D2), 400 ml/L (D3). The second factor is the herbicide oxyfluogen (O) with a concentration consisting of 4 levels, namely: control (o0), 1 ml/L (O1), 2 ml/L (O2), 3 ml/L (O3). From these 2 factors, 16 treatments were obtained with 2 replications, and the number of samples was 32 sample plots, plot area 1 m2, distance between replicates 1 m from 2 factors. The results of data analysis showed that administration of durian seed extract and administration of oxyfluogen had a very significant effect on the percentage of weed mortality in oil palm plantations, but the interaction had no significant effect on the first week and second week after application. The best treatment was the application of a combination of 400 ml/L of durian seed extract with 3 ml/L of oxyfluogen which killed the highest weeds around 81% after two weeks of application. Durian seed extract has potential as a bioherbicide, which can be used as an alternative technique in weed control systems in oil palm plantations.

Abstract

Dengue fever is transmitted through the bite of a female mosquito that stores the dengue virus in its eggs, then the virus will be transmitted to humans through bites. The right way to control the spread of Dengue Fever is to control the vector population through the use of bioinsecticides whose basic ingredients come from plants containing chemicals that are toxic to insects. This study aims to determine the effectiveness of aromatherapy candle media made from nutmeg leaf (Myristica fragrans houtt) in killing the Aedes aegypti mosquito. This research uses experimental research with post test only group control design method. The number of samples used in one experiment was 50 Aedes aegypti mosquitoes. This research process uses palm wax wax media, and the composition of nutmeg leaf powder is 50 grams and wax is 100 grams. The results showed that for 12 hours every 2 hours the number of dead mosquitoes was monitored, the average number of mosquitoes that died with 3 trials was 60% experiment, while external factors, namely temperature and humidity measurements in both rooms did not affect the mortality of mosquitoes.

Abstract

Pteraeolidia is a member of Cladobranchia that can be found in Indonesia. This study aims to investigate the phylogenetic and geographyc relationship within Pteraeolidia species not only in Indonesia. Sequences of Pteraeolidia COXI gene, were extracted from the GenBank and were analysed using K3Pu+F+I+G4 model. Haplotypenetwork analyses was used for the specific investigation. The likelihood phylogenetic tree of Pteraeolidia reveals monophyletic of P. ianthina. However, it splits into two branches with high distance matrix. P. semperi joins into one branch, despite, five sequences of P. ianthina which joined in the brach cause the clade become nonmonophyly. P. semperi not only found in East Australia but also in Sulawesi and Pacific.
