Telah dilakukan penelitian mengenai kandungan total fenolik, flavonoid dan tanin terkondensasi dari hasil pemisahan kromatografi kolom dan uji aktivitas antibakteri fraksi daun sesewanua terhadap bakteri Streptococcus mutans dan escherecia coli. Pemisahan kromatografi kolom dimulai dengan proses ekstraksi maserasi menggunakan pelarut metanol. Hasil penelitian menunjukkan bahwa kandungan total fenolik tertinggi pada fraksi metanol yaitu 135,497 mg/g, kandungan total flavonoid tertinggi pada fraksi etil asetat yaitu 102,647 mg/g dan kandungan total tanin terkondensasi tertinggi pada fraksi metanol yaitu 53,543 mg/g. Uji aktivitas antibakteri menggunakan konsentrasi fraksi 40%, 60% dan 80% dilakukan sebanyak tiga kali pengulangan. Larutan DMSO 10% digunakan sebagai kontrol negatif dan kloramfenikol sebagai kontrol positif. Hasil menunjukkan bahwa fraksi n-heksana tidak memiliki zona hambat sedangkan fraksi etil asetat dan fraksi metanol daun sesewanua dapat menghambat bakteri Streptococcus mutans dan Escherecia coli. Konsentrasi fraksi 80% menunjukkan zona hambat yang paling besarResearch has been conducted on the total content of phenolics, flavonoids and condensed tannins from the results of column chromatography separation. Antibacterial activity test of leaf fractions was also performed against Streptococcus mutans and Escherecia coli. The separation of column chromatography was initialized with the process of maceration using methanol as solvents. The highest total phenolic content obtained in the methanol fraction was 135.497 mg/g, the highest total flavonoid content obtained in the ethyl acetate fraction was 102.647 mg/g and the highest total condensed tannin content in the methanol fraction was 53.543 mg/g. Antibacterial activity test was done triplicates using the 40%, 60% and 80% fraction. DMSO 10% was apllied as the negative control and chloramphenicol as the positive control. The results showed that the n-hexane fraction did not have an inhibition zone while the ethyl acetate fraction and the methanol fraction of the leaves can inhibit Streptococcus mutans and Escherecia coli. Moreover, 80% fraction showed the largest inhibition zone.

Tuff ring Geoelectric Resistivity Dipole-dipole The research has been done to identify the subsurface structure of the tuff ring in plantation area Mahawu using geoelectric method of dipole-dipole configuration.It has been divided into two lines measuring with the length of 480 m for each lines, one space 10 m between the electrodes and the line 2 has 240 m length with spaces 5 m between electrodes. The data was obtained and processed using software RES2DINV to get an image of the structure below the tuff ring into two dimensions. The results of data processing shown an image of resistivitas beneath the surface on the line 1. In general, it can be seen that the resistivitas beneath the surface line 1 is dominated by resistivitas more than 300 Ωm (purple colour image). Especially in meter 250-260 and meter 280-290, there are two zones with resistivitas value that is relatively small at less than 50 m. While on the line two, the resistivitas value is less than 60 Ωm (blue and green coloured zone ) that form patterns extend from the maximum depth to the surface, visible form a funnel/the cust from a depth of about 40 m (under electrodes to 18 or in meters to 90) To the surface (under electrodes 25 – 33 or in meters 125 -165) is directed to the northwest-southeast with the angle of inclination of about 40°42°and the resistivitas pattern elongated funnelshaped by contrast it also limited by the high resistivitas (> 300 Ωm) which is a structure with high density and less conductive.

Lampu adalah sumber cahaya buatan yang digunakan untuk membantu aktivitas manusia dan merupakan salah satu alat yang mengkonsumsi daya listrik terbanyak. Pencahayaan lampu pada saat ini hanya dikontrol secara manual dengan dua keadaan yang tentunya kurang efisien. Pengontrolan intensitas cahaya secara otomatis mampu meningkatkan efisiensi penggunaan lampu dari segi energi maupun pada pencahayaan agar mengikuti standar. Penelitian ini menggunakan sensor LDR sebagai pendeteksi cahaya, sensor ultrasonik (HC-SR04) sebagai pendeteksi jarak dan IC LM317 untuk mengatur tegangan. Logika fuzzy digunakan sebagai pengontrol intensitas cahaya yang diprogram ke modul Arduino Uno R3. Komponen ini disatukan dalam ruangan kecil yang berukuran 30 x 30 x 30 cm sebagai prototipe. Hasil penelitian menunjukkan bahwa sistem mampu mengatur pencahayaan ruangan sesuai SNI 03-6575-2001 dan dapat mendeteksi keluar-masuknya orang di ruangan. Perbandingan konsumsi daya selama 4 jam antara lampu dengan sistem dan yang tidak adalah sebesar 0.008027 kWH atau sekitar 57.21% dari daya yang dikonsumsi secara keseluruhan.Lamp is an light source that is used to assist humans and its one of the device that consumes a lot of electric power. Lighting lamps at this time only controlled manually with two conditions which is certainly less efficient. Controlling the intensity of the light automatically can increase the efficiency of used energy and lighting to follow the standards. This research uses the LDR sensor as a light detector, ultrasonic sensor (HC-SR04) as a proximity sensor and LM317 IC to regulate the voltage. Fuzzy logic is used to control the light intensity which programmed into the Arduino Uno R3 module. These components are put together in a small room with a length = 30, width = 30 and height = 30 cm as a prototype. The results show that the system is able to regulate room lighting according to SNI 03-6575-2001 and can detect if people moving in and out of the room. The comparison of power consumption for 4 hours between lights that are connected with the system and without connection is equal to 0.008027 kWH or about 57.21% of the total power consuming.

Transesterification Fatty acids Tuna (Thunnus albacares) Research on the effect of the transesterification method of tuna fish head oil (Thunnus albacares) using methanol and ethanol reagent has been carried out. The purpose of this study was to determine the effect of methanol and ethanol reagents on the transesterification process. The research methodology used in the transesterification of tuna fish oil (Thunnus albacares) is by using two alkyl source reactants, namely methanol and ethanol where the fatty acid alkyl esters were analyzed by gas chromatography. Transesterification using methanol reagent was carried out with BF3 acid catalyst and ethanol reagent was carried out with alkaline NaOH and KOH catalysts. The results showed that the main fatty acid content in fish oil in tuna's head was DHA, palmitate and linoleic. Transesterification of fish oil using acid (BF3 and methanol) and alkaline (NaOH and ethanol) methods resulted in the slightly different of fatty acid composition. DHA fatty acid has the highest content in ethanol reagent with KOH catalyst, namely (33.55%). Palmitic fatty acid (23.09%) was higher in the ethanol reagent with NaOH catalyst. And linolelaidic fatty acid was higher in transesterification using methanol reagent with BF3 catalyst, namely (20.98%).

The research methodology used in the transesterification of tuna fish oil (Thunnus albacares) is by using two alkyl source reactants, namely methanol and ethanol where the fatty acid alkyl esters were analyzed by gas chromatography. Transesterification using methanol reagent was carried out with BF3 acid catalyst and ethanol reagent was carried out with alkaline NaOH and KOH catalysts. The results showed that the main fatty acid content in fish oil in tuna's head was DHA, palmitate and linoleic. Transesterification of fish oil using acid (BF3 and methanol) and alkaline (NaOH and ethanol) methods resulted in the slightly different of fatty acid composition. DHA fatty acid has the highest content in ethanol reagent with KOH catalyst, namely (33.55%). Palmitic fatty acid (23.09%) was higher in the ethanol reagent with NaOH catalyst. And linolelaidic fatty acid was higher in transesterification using methanol reagent with BF3 catalyst, namely (20.98%).","PeriodicalId":53333,"journal":{"name":"Jurnal MIPA","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89028160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Garcinia mangostana Penetration enhancer Antioxidant cream Sun exposure with UV radiation is one of the triggers for free radicals that cause premature aging (photoaging), characterized by hyperpigmentation, wrinkles, and decreased skin elasticity. The solution to this problem is the use of antioxidants that can prevent the formation of free radicals. The purpose of this study was to formulate an antioxidant cream dosage form from pericarpium extract of mangosteen pericarpium with different penetration enhancers to obtain the best percentage of penetration and retention in the skin. Pericarpium extract of mangosteen fruit was prepared by maceration method using 70% ethanol, then the antioxidant activity and the phenolic content were measured and were used as an active ingredient in the cream formula. Formula F1-F3 were made, their physical characteristics were evaluated, and in vitro penetration testing was carried out. In vitro penetration testing was carried out on F2 and F3 containing extracts. The IC50 value of the extract against DPPH was found to be 7.514 μg/mL and the phenolic content was found to be 112,70 ± 0,80 mgGAE/g. The percentage of penetration, retention percentage, and flux value were 9.96% ± 0.075%, 37.951% ± 0.103%, 3.037 ± 0.023 μg/cm2.hour respectively for F2 and 7.872% ± 0.078% , 33.874% ± 0.259%, 2.400 ± 0.024 μg/cm2.hour, respectively for F3. From the results of statistical analysis, it was concluded that F2 was the best formula with homogeneous physical characteristics, had a yellowish color, emulsion type w/o, pH value of 6, adhesion of 11.05 ± 0.87 seconds, and diameter of spreadability of 6.20 ± 0.10 cm.

Pendidikan merupakan komponen yang penting dalam pembangunan suatu negara. Dalam upaya pembangunan pendidikan diperlukan kebijakan yang disesuaikan dengan karakteristik suatu wilayah. Tujuan penelitian ini adalah memetakan Kabupaten/Kota yang memiliki kemiripan berdasarkan beberapa variabel pendidikan juga mengetahui korelasi antar variabel pendidikan dengan menggunakan analisis biplot. Data yang digunakan adalah data sekunder tahun 2018 yang diperoleh dari Badan Pusat Statistik (BPS) Provinsi Sulawesi Utara dan Kementerian Pendidikan dan Kebudayaan. Hasil dari analisis biplot penelitian ini menunjukkan bahwa Kabupaten/Kota yang memiliki karakteristik pendidikan yang relatif sama yaitu Kepulauan Sangihe, Kabupaten Minahasa Tenggara, dan Kabupaten Siau Tagulandang Biaro. Dimana keragaman yang terbesar terjadi pada jumlah SMP/sederajat, dan keunggulan dari suatu objek terdapat pada Kabupaten Bolaang Mongondow Utara memiliki nilai tertinggi pada variabel Angka Partisipasi Kasar (APK) SMP/sederajat. Kemudian variabel - variabel yang memiliki korelasi positif yaitu Angka Partisipasi Kasar (APK) SD/sederajat dan Angka Partisipasi Murni (APM) SD/sederajat yang artinya jika nilai Angka Partisipasi Kasar (APK) SD/sederajat bertambah, maka bertambah pula nilai Angka Partisipasi Murni (APM) SD/sederajat begitu juga sebaliknyaMathematics is one of the subjects that is taught in every educational stage, yet the fact shows that mathematics remains the one subject feared by students, and this condition can affect the students’ learning outcome. One of the factors which affects the learning outcome is the teacher’s teaching skill, which does not only involve their skill in a particular field, but also their creativity in developing that occupied field as well as their readiness to learn, where this will form the first step in initiating the teaching and learning activity. So this study was conducted to find out the relationship of the teacher’s teaching skill and readiness to learn with the mathematics learning outcome in class X IPS SMAN 7 Manado, using the Chi-Square test. The Chi-Square test is used to determine the relationship of a dependent variable with an independent variable, depending on a nominal or ordinal scale. This research has shown that there is no significant relationship between the teacher’s teaching skill and readiness to learn with the students’ learning outcome (p < 0,05)
