Abstract

The leaves and fruits of Indonesian Syzygium spp such as white pakoba, red pakoba and bombongan have been extracted by ethanol. The ethanolic extract was partitioned with polar solvent gradient using n-hexane, ethyl acetate and n-butanol repeatedly. Each fraction was tested for antidiabetic activity and exhibited varying degrees of antidiabetic activity when tested with α-glucosidase method. Antidiabetic test indicated that the ethyl acetate and butanol fractions of the leaves of pakoba white, red pakoba and bombongan has potential as a source of active compounds.

Abstract

Dalam penelitian ini, dilakukan analisis kadar Fe(III) pada sampel air sumur galian yang dikonsumsi masyarakat sebanyak 10 sampel yang tersebar dibeberapa wilayah Kota Gorontalo. Sampel diasamkan dengan 0.3 mL HNO3 4M dan 0.5 mL KSCN 2M dan absorbansi diukur dalam Spektrometer UV-Visible. Nilai absorbansi dari hasil pengukuran larutan standar dengan deret konsentrasi 0.1, 0.3, 0.5, 0.7 dan 1 ppm larutan induk Fe 100 ppm diperoleh persamaan regresi linier y = 0.000x + 0.016 dengan nilai regresi (R2) = 0.9860. (λMax) 490 nm dengan nilai absorbansi (A) tertinggi yakni 0.043. Data ini digunakan untuk pengukuran sampel di lokasi I. Untuk Lokasi II, Nilai absorbansi dari hasil pengukuran larutan standar dengan deret konsentrasi 0.1, 0.3, 0.5, 0.7 dan 1 diperoleh persamaan regresi linier y = 0.036x + 0.006 dengan nilai regresi (R2) 0.9800. (λMax) 510 nm dengan nilai absorbansi (A) tertinggi yakni 0.025. Hasil pengukuran sampel untuk Lokasi I yakni kode sampel A = -0.1060, B = -0.0303, C = 0.3780, D = 0.1667 dan E = 0.3636. Untuk Lokasi II yakni kode sampel A = 0.175, B = 0.050, C = 0.3780, D = 0.050 dan E = 0.675. Disimpulkan bahwa, kandungan konsentrasi Fe di 5 lokasi ini masih dibawah NAB yakni ˂ 1 mg/L karena konsentrasi Fe yang dianjurkan oleh WHO minimal adalah 1 mg/L. Pada air tanah bervariasi mulai dari 0,01 mg/l - 25 mg/l.

Abstract

The aim of this research is to remove Pb(II) from waste water of Tolangohula sugar factory, Gorontalo. In this study, coagulation technique was developed using chitosan as coagulant. Chitosan was obtained from Peneaus monodon shell. The effect of coagulant mass was studied by varying the mass of chitosan: 0, 2.5, 5, 7.5 and 10 g. In addition, effect of pH was also examined by varying the pH of solution: 2, 6, 7, 8, 9 and 10. The results showed that the utilization of 10 g chitosan gave the optimal Pb(II) removal of 72.36% or 22.28 x 10-6 mg/g. Additionally, Pb(II) removal was optimum (83%) or 25.44 x 10-6 mg/g at pH 9. It could be concluded that chitosan coagulant had the ability to adsorb the Pb(II) in the waste water from Tolangohula sugar factory Kabupaten Gorontalo.

Abstract

Pulut corn has various physicochemical characteristics compared to non-pulut corn. Adequate nutritional content makes pulut corn potentially capable of supporting the diversification of the food industry, one of which is used as fermented corn milk. The purpose of implementing this activity is for the community to gain knowledge about the processing of corn pulut as fermented milk. The activity was carried out in Bumi Bahari Village, Popayato District, Pohuwato Regency, Gorontalo Province in November 2022. The resulting data were analyzed descriptively which described the implementation of the activities, including preparation and implementation. Based on the results of observations, it was found that the people involved were very enthusiastic and showed a positive and independent attitude during the activity process. In addition, from the results of interviews with the training participants, it was found that they were greatly helped by this training activity. So far, the training participants only know that pulut corn is processed as boiled pulut corn, and Gorontalo's special food.

Abstract

Corn (Zea mays) is a widely cultivated crop in Gorontalo and has high economic value as well as an important role in food security. Fertilization is one of the key factors that influence the productivity of corn plants. This research aims to determine the combination of NPK fertilizer doses granulated with Biochar-Chitosan in enhancing the growth and productivity of corn plants, as well as its impact on the quality of total N soil content. The study was conducted by planting corn, applying fertilizer, and observing its growth through measurements of plant height, leaf length, stem diameter, cob weight with husk, and cob weight without husk. The observational data were then analyzed descriptively, summarizing or classifying the data set to provide an overview of the data. Additionally, the analysis of soil N-total content was conducted before and after the application of fertilizers. The research results show that the combination of NPK-Biochar fertilizer doses has a significant impact on the growth and productivity of corn plants. The 7.5-gram NPK-Biochar fertilizer dose yielded the best results in increasing plant height, number of leaves, stem diameter, and cob weight with and without husks compared to other doses. Soil chemical property analysis also indicates that the application of NPK-Biochar fertilizer has a positive impact on the quality of the soil's total nitrogen content.
