This study aims to determine the levels of alkaloids compound in the extract of Akar Bulu(Merremia vitifolia) leaves. The leaves of M.vitofilia are widely used by the people of Luwu (South Sulawesi) to treat wounds in diabetics. Stages in this work include sample preparation (collection, drying and sieving); ethanol maceration, evaporation and UV-Vis Spectrofotmetry analyzing. Extraction of the chemical content of the leaves of M.vitifolia was carried out by maceration method using 96% ethanol 1600 mL. Determination of alkaloid levels in the ethanol extract of M.vitifolia leaves using the UV-Vis spectrophotometer method at a maximum wavelength of 345 nm. The results showed that the alkaloid content of M.vitifolia leaves was 9.51 mg/g.

Identification of mineral and element of Slag Nickel from PT. Vale Sorowako

2021-11-03T09:52:53+07:00

We report the mineral and element analysis of Slag Nickel that produced from nickel smelter at the PT. Vale Sorowako. The sample were directly collected from the mining site and crushed until it become powder. The element analysis performed by X-Ray Fluorescence (XRF) and the mineral identification made by X-ray diffraction (XRD). The XRF data showed that the Slag Nickel contains Fe (79.72 %), Si (10.8 %), Mn (2.23%), and Ni (2.04%). The semiquantitative analysis of XRD pattern indicated that the main minerals in the slag nickel are hematite (Fe3O4) and silica (SiO2). There are Those data reveal that slag nickel still contains many valuable elements which have potential application for advanced technology. Further research is needed to extract those element or mineral from slag nickel.

Selection and Correlations of Character Agronomy of Onion (Allium cepa L.) Var. Bima in Salinity and Drought Condition In Vivo

2021-11-03T12:07:29+07:00

Onion exports need to be increased through increased production. However, the area of land for the cultivation of this commodity has diminished due to the conversion of land to settlements and industry so that only marginal land is not productive for onion cultivation. This study aims to estimate the agronomic characters capable of being used as an indirect selection on the character of salinity and drought conditions and to obtain genotypes of onion are able to adapt to the artificial conditions of salinity and drought in vivo. Genetic material used is Bima onion bulbs with augmented design with a spaced planting system, with a spacing of 20 cm x 20 cm, and each hole contains 1 shallot bulb using a head-to-row system. This study uses a combination of NaCl and PEG 6000 as a salinity and drought selection agent. The results of this study indicate that agronomic characters that have a strong and positive correlation value and can be used as a direct selection character for the vegetative phase, namely root volume and root length, generative phase, namely age of harvest and yield components, namely the weight of parent plant tubers, the weight of saplings and tuber weights per plant. There are nine genotypes suspected to be able to adapt to artificial conditions of salinity and drought in vivo, namely S3-1, S3-2, S3-3, S4-1, S4-2, S4-3, S5-1, S5-2, and S5-3 resulted from Scatterplot analysis for two variables and from a comparison of five parameters to tuber weights per plant.

2021-11-03T11:43:47+07:00

Research has been conducted to find out the amount of liquid fractions resulting from polypropylene plastic pyrolysis (PP) and the selectivity of Mesoporous Silica (MS), Ni/SM, and NiMo/SM against the fraction of gasoline and diesel pyrolysis results of polypropylene plastic (PP). The method in this study is pyrolysis method (heating in the absence of oxygen) and analysis of liquid fraction of pyrolysis result using GCMS (Gas Chromatrography Mass Spectrometry). In this study, the largest number of liquid fractions produced on pyrolysis with Ni-MS catalyst was 71.68 wt.%. GCMS analysis showed all selective catalysts for gasoline for mesoporous silica (MS), Ni/MS, and NiMo/MS by 73.75%, 57.21%, and 80.08%.

Effectiveness of MKM Fertilizer and Bean Sprouts Extract on the Growth and Production of Tomato (Lycopersicum Esculentum Mill.)

2021-11-03T10:46:02+07:00

he tomato plant is a multipurpose commodity, apart from being used vegetables,tomatoes are also used as raw materials for cosmetics, medicines as well as raw materials for the food processing industry. This study aims (1) to determine the effect of using MKM fertilizer and bean sprouts extract on growth and production of tomato plants (2) know the dosage of MKM fertilizer and bean sprouts extract which are effective in supporting growth and production of the tomato plant. This research was conducted in the land Experiment II, Faculty of Agriculture, Cokroaminoto Palopo University on the month January to March 2020. This study used a randomized design method Groups (RBD) were carried out with 6 treatments with 4 replications. So that there are 24 experimental units. P0 = without treatment, P1 = MKM fertilizer 100 grams / plant and 75 ml bean sprouts extract / plant, P2 = MKM 150 fertilizer gram / plant and 100 ml bean sprouts extract / plant, P3 = MKM 200 fertilizer gram / plant and 125 ml of bean sprouts extract / plant, P4 = MKM 250 fertilizer gram / plant and 150 ml bean sprouts extract / plant, P5 = MKM 300 fertilizer gram / plant and 175 ml of bean sprouts extract / plant.The results of this study indicate that the provision of MKM fertilizer 250 grams / plant and 150 bean sprouts extract ml / plant (P4) can significantly effect the number of leaves, flowering age, and fruit weight. Other parameters such as plant height and number of fruits shows results that have no real effect, but it appears that P4 has an average value of plant height and number of fruit higher than other treatment. This is thought to have occurred due to the influence of the nutrients N, P and K in natural MKM and ZPT fertilizers such as auxins, cytokinins and gibberellins in bean sprouts extract that can meet the needs of plants so shows a good response in plant growth and production tomato.

Designing a monitoring application for the informatics study program of the engineering faculty of Cokroaminoto University Palopo

2021-11-03T12:16:12+07:00

Monitoring is carried out at a university to improve the quality of the teaching and learning process. Starting from the initial lecture process to the end of one semester of lecture, lecturers are required to fill in the activity monitoring sheet used to determine the subject matter of a course to be delivered to students. The monitoring sheet is also used as evaluation material for course lecturers if there is a material that has not been delivered. The process of filling in monitoring in the informatics study program so far is still manual using paper. It is not inconvenient to monitor, but with the current conditions, the manual process is transferred online by utilizing a google service known as google form. The purpose of this research is to design a recovery monitoring application that is used by lecturers when they finish teaching. The method used in this research is a research method that uses system analysis and design, system requirements analysis, system design, including the making of stage diagrams. Meanwhile, data collection using observation methods, interview methods, and literature study. The research results were in the form of material reports, teaching methods, and the number of student attendance at each meeting. The report is adjusted to the reporting format used by the head of the study program. Each lecturer will be able to fill in lecture monitoring through a website-based application. The head of the study program can directly monitor lecturer activities without having to ask or directly monitor lecturers when teaching

The Use of Edmodo as a Virtual Teaching Media of Listening

2021-11-03T09:12:50+07:00

This study aims at finding out whether Edmodo is effective in teaching listening
virtually at the sixth semester of Cokroaminoto Palopo University. This study is preexperimental
design which consists of pre-test, treatment and post-test. The population of this study
is the sixth semester of Cokroaminoto Palopo University. The technique used to select
the sample is simple random sampling. The data is analyzed using significant t-test (paired
sample t-test). The result of the study shows that the value of mean score of pre-test (61.50) is
lower than the mean score of post-test (68.67). It means that the use of Edmodo is effective in
teaching listening. The result of paired sample t-test shows that the value of sig. (2-tailed) is
lower than alpha (α) (0.000<0.05), It means that Null Hypothesis (H0) is rejected and
Alternative Hypothesis (H1) is accepted. Therefore Edmodo is significantly effective in
teaching listening virtually at the sixth semester of Cokroaminoto Palopo University.
