Abstract

Giant swamp taro (GST/Cyrtosperma merkusii), a local North Sulawesi coastal plant, is underutilized but has high po-tential for cultivation as a paludiculture plant on rewetted peatland restorations. GST has high starch content and is currently being explored for potential use. This study explored the potential of using the biomass pulp yielded as resi-dues of the starch extraction process. Endolichenic fungi (Trichoderma reesei and Aspergillus aculeatus) isolated from local lichens, were inoculated on the GST biomass in a solid state fermentation (SSF). Findings of this study indicate that both isolates were effective in degrading the lignocellulosic biomass of GST over an incubation period of 28 days, focusing on cellulose as the targeted polysaccharide. Although T. reesei requires a more adjusted carbon source than A. aculeatus to effectively process the biomass, the effectiveness of the bioprocess after adjustment matched that of A. aculeatus. When hemicellulose is targeted, other strategies must be used to prevent destruction of hemicellulose during the process. This phenomenon should be explored in further studies. These findings indicate the potential of industrial-izing cellulose-based products from GST using local North Sulawesi fungal species abundantly occurring in local eco-systems.

Abstract

Beras, umbi-umbian, dan pangan olahan dari tepung-tepungan dan pati seperti mie, pasta dan bakery merupakan bahan pangan utama bagi masyarakat Indonesia. Tanaman daluga berpotensi sebagai sumber pangan yang baik, mempunyai komposisi karbohidrat dengan kompisis amilosa dan amilopektin yang baik sehingga memberikan karakter pencernaan yang lebih sehat di pangan olahannya dengan mengurangi percepatan pembongkaran karbohidrat menjadi gula. Tujuan penelitian ini untuk mengetahui pengaruh pemberian komposit pati daluga, tepung jagung dan tepung beras terhadap kadar glukosa darah Rattus novergicus yang diinduksi high fat diet. Pengujian in vivo menggunakan 18 ekor Rattus novergicus jantan dengan modelling syndrom metabolic. Darah tikus dikoleksi melalui vena orbitalis mata pada hari ke-0, 7 dan 14 untuk pengujian kadar glukosa darah. Metode pengujian ex vivo dilakukan nekropsi setelah perlakuan 14 hari dengan pengambilan sampel usus bagian jejunum untuk pengamatan laju absorbsi glukosa pada usus. Data dianalisa menggunakan perangkat lunak R-Software. Hasil penelitian menunjukkan bahwa data yang diperoleh pada hari ke-14 terdapat perbedaan signifikan antara kelompok (p<0,05) sedangkan, pada hari ke-7 tidak adanya perbedaan yang signifikan antar kelompok (p>0,05). Pemberian komposit pati daluga, tepung beras dan tepung jagung memiliki potensi yang dapat meningkatkan kadar glukosa darah tikus putih yang diinduksi high fat diet.

Abstract

This study used catfish Clarias gariepinus as an experimental animal, which given supplementation of curcumin and thyroxine hormone. The results showed that during the reproductive period there was an increase in body weight of female catfish in line with the development of the gonads. Through the histology of the gonads, it appeared that oocyte development occurs over time.  The results of liver histology showed a high activity of hepatocyte cells as indicated by the formation of vacuoles, as the storage site for vitellogenin, in their cytoplasm. Supplementation of curcumin and thyroxine was able to increase the specific growth rate of catfish, and the catfish group that given the combination treatment of curcumin supplementation (5 g.kg-1 of feed) with thyroxine hormone (0.1 mg.kg-1 of feed) showed the more optimal results.

Abstract

The Pancasila Student Profile Strengthening Project or often referred to as the P5 Project is an effort to support the realization of student figures based on the Pancasila foundation through the process of reviewing student learning materials based on projects. One of the topics of the P5 activities carried out at SMA N 2 Ratahan is entrepreneurship, and coconut oil processing is the theme raised. The implementation method of community service activities consists of dissemination, training/technology transfer, as well as monitoring and evaluation at the final stage. Through this community service activity, there is an increase in the level of community empowerment in this case students and teachers, namely increasing student knowledge and skills about processing coconuts into coconut oil and blondo using more modern tools. The activities include production and packaging. This activity has also been able to improve students' life skills to be able to become entrepreneurs later.

Abstract

This study aims to determine the effect of clove oil concentration and time of immersion in clove oil on the anesthesia, recovery time, and physiological responses in the payangka fish (Ophieleotris aporos). The experimental design was completely randomized with a 6 x 3 factorial arrangement. The first factor was a concentration of clove oil consisting of six levels i.e., 0.02; 0.03; 0.04; 0.05; 0.1, and 0.2 ml/L of water. The second factor was a time of immersion consisting of three levels i.e., 1; 3; and 6.5 hours. Results showed that the concentration of clove oil significantly (p<0.05) affected the anesthesia time and the recovery time after immersing. The length of immersing and concentration of clove oil also significantly (p<0.05) affected the concentration of glucose, but not significantly (p>0.05) affected the concentration of cholesterol. It showed that clove oil can be used as anesthetization for payangka fish in the appropriate dose. The optimal concentration of clove oil that can be used as anesthesia for the transportation of live payangka fish is 0.02 ml/L of water. Meanwhile, for handling activities on payangka fish, a clove oil concentration of 0.03 ml/L of water is recommended

Abstract

Schools largely contributes to community wastes. Waste management movements are required to reduce impacts of community wastes. Tombatu 1 State Highschool, Southwestern Minahasa is a well recognized school in the vicinity. Their large studentbody are the biggest contributors to community local wastes. Losida (biopore) is a simple solution for managing organic waste by convertion to beneficial compost soil restoration on school grounds. The purpose of this activity was simple biopore application and management by teachers and students as a manifestation of the P5 program. Through this activity knowledge and skills of the students as a steward of the environment were honed. This activity serves a media for disemination and training inspiring students to grow for their love of the environment. Also, a media for science application of involved lecturers, impacting the society outside of campus grounds in the efforts of achieving on of the institution’s performance indicators (IKU Perguruan Tinggi).

Abstract

The snake-head gudgeon or payangka fish (Ophieleotris aporos), tilapia fish or mujair (Oreochromis mossambicus), and marble goby or betutu fish (Oxyeleotris marmorata) are economically important fish in Lake Tondano. However, numerous community activities can disrupt aquatic biodiversity, declining Lake Tondano environmental conditions, and other factors. This study aimed to determine the relationship between length and weight and the habitat conditions of Ophieleotris aporos, Oreochromis mossambicus, and Oxyeleotris marmorata. The method used in this study was purposive sampling with research stations located at Remboken (station 1), Kakas (station 2), and Tondano Estuary (station 3). Sampling was carried out 5 times in every 10 days. The weight and length of the fishes caught in Lake Tondano were 2-60 g and 1-8 cm (Ophieleotris aporos); 9-180 g and 6-25.5 cm (Oreochromis mossambicus); and 16-30 g and 2.6-26.5 cm (Oxyeletotris marmorata), all of them have an allometric growth pattern. Oreochromis mossambicus is the most commonly caught fish in all research stations. The research station with the best level of water fertility is Remboken Station. The habitat characteristic of Lake Tondano was 25-290C of water temperature; brightness of 1.34-2.66 m; depth of 4.23-11.8 m; pH of 6.7-7.8; and dissolved oxygen of 2.27-6.31 mg/L, which still supports the well-being of the fish.
