Abstract

Abstract: Study of the success of producing coconut oil processed by acidification method based on analysis of amino acids in fatty cream using HPLC has been carried out. Purpose of this study was to determine the quality of coconut oil that is made by acidification methods to fit the SNI and APCC standard. Successful method of acidification can be seen from the types of amino acids were analyzed using HPLC instrument. Whereas, the protein content of fatty cream were analyzed by Kjeldahl method and type of amino acid that is formed using HPLC. Research results showed that the samples made of coconut oil has a FFA content of 0,36%, protein content of 21,81%, color and smell are normally. This results in accordance with the SNI standard, but still below the standard of APCC. HPLC analysis showed that the profile of amino acids formed from the sample failed and successful is different from the non-lysine and leucine in the sample that caused the high failure rate of rancidity. Abstrak: Telah dilakukan pembuatan minyak kelapa yang diproses dengan metode pengasaman melalui analisis asam amino dengan menggunakan High Performance Liquid Chromatography (HPLC). Tujuan penelitian ini adalah untuk mengetahui kualitas minyak kelapa yang dibuat dengan metode pengasaman agar sesuai dengan standar SNI dan APCC. Keberhasilan metode pengasaman dapat dilihat dari jenis asam amino yang dianalisis menggunakan HPLC dari sampel minyak yang diperoleh. Sedangkan residu dianalisis kadar proteinnya dengan metode Kjeldahl dan jenis asam amino yang terbentuk dengan menggunakan HPLC. Penelitian menunjukkan bahwa sampel minyak kelapa yang dibuat memiliki kadar FFA sebesar 0,36%, kadar protein sebesar 21,81%, warna dan bau yang normal. Hasil ini sesuai dengan standar SNI, namun masih di bawah standar APCC. Analisis HPLC menunjukkan bahwa profil asam-asam amino yang terbentuk dari sampel gagal dan berhasil adalah berbeda yaitu ketidakberadaan lisin dan leusin pada sampel gagal yang menyebabkan tingginya tingkat ketengikan.

Abstract

 Abstract: The process of learning colligative properties have tend to learn chemistry as a product so that students have difficulty understanding this topic. Guided inquiry-based learning laboratory is a learning strategy that can accommodate chemistry learning as product and process. This research aims to know the effect of practice learning strategy based on guided inquiry to the instructional result of year 12 of science of MA Ma’arif 7 Lamongan on the topic of colligative properties of solution. The instructional result is the score from a report of practice result and written test. The subject of this research is 34 students of 12-E IPA class of MA Ma’arif 7 Lamongan in the academic year 2015-2016. The research design that used is the one group pretest-posttest. The research instruments used written test and observation checklist. The written test measured the result of validated instrcution before it is used and has reliability 0,802. The obtained data then was analysed with a descriptive analysis and different test. The different test used t-paired test. Paired t-test results obtained sig 0,000 which is smaller than 0.05 so H0 is rejected by 95% reliability. Based on these results it can be concluded that there was significant improvement of learning outcomes using laboratory procedures of colligative properties. The average value of student learning outcomes was increased from 61.05 into 81.44. This increase showed that the practice learning based on guided inquiry had a good level of effectiveness.Abstrak: Proses pembelajaran materi sifat koligatif cenderung hanya mempelajari kimia sebagai produk sehingga siswa mengalami kesulitan dalam memahami topik ini. Pembelajaran praktikum berbasis inkuiri terbimbing merupakan strategi pembelajaran yang dapat mengakomodasi pembelajaran kimia sebagai produk dan proses. Penelitian ini bertujuan untuk mengetahui pengaruh strategi pembelajaran praktikum berbasis inkuiri terbimbing terhadap hasil belajar siswa kelas XII IPA Madrasah Aliyah Ma’arif 7 Lamongan pada materi sifat koligatif larutan. Hasil belajar berupa nilai yang berasal laporan hasil praktikum dan tes tulis. Subyek penelitian ini adalah 34 siswa kelas XII-E IPA Madrasah Aliyah Ma’arif 7 Lamongan tahun pelajaran 2015-2016. Rancangan penelitian yang digunakan adalah the one group pretest-posttest. Instrumen penelitian menggunakan tes tulis dan lembar observasi. Tes tulis untuk mengukur hasil belajar divalidasi sebelum digunakan dan memiliki reliabilitas 0,802. Data yang diperoleh selanjutnya dianalisis dengan analisis deskriptif dan uji beda. Uji beda menggunakan uji t-paired. Hasil uji-t berpasangan diperoleh sig 0,000 yang berarti lebih kecil dari 0,05 sehingga H0 ditolak dengan reliabilitas 95%. Berdasarkan hasil tersebut dapat disimpulkan bahwa terdapat peningkatan hasil belajar yang signifikan pada pembelajaran praktikum dengan menggunakan prosedur praktikum sifat koligatif larutan. Nilai rata-rata hasil belajar siswa meningkat dari 61,05 menjadi 81,44. Peningkatan ini menunjukkan pembelajaran praktikum berbasis inkuiri terbimbing memiliki tingkat efektivitas yang baik.

Abstract

Abstract: The increasing of antimicrobial resistance in medical field has become a serious problem which is have to be solved by exploring raw material on natural product. Seaweed or macroalgae is one of marine natural wealth of Indonesia’s sea. In this research, lipid extraction of seaweed (macroalgae) Ulva fasciata has been done according to Folch method by using sochlet and mixure of solvent namely chloroform:methanol (2:1/ (v/v)). The result gave two phase namely chloroform phase (0,6% (v/b)) and methanol phase (7,79% (v/b)). Furthermore, both of phase of crude extract lipid Ulva fasciata were tested their antibacterial activities against Bacillus cereus bacterial which is three times. Tetracyclin is used as positive control and the solvent (methanol-chloroform) is used as negative control. The results were both of phase gave antibacterial activity namely 0,02 mm/ μg extract for chloroform phase and 0,02 mm/ μg extract for methanol phase.Abstrak: Peningkatan kasus resistensi antimikroba pada dunia medis telah menjadi masalah yang serius sehingga perlu dilakukan pengeksplorasian bahan baku untuk antibiotik khususnya dari bahan alam. Rumput laut (makroalga) merupakan salah satu kekayaan alam hayati laut Indonesia yang memiliki kandungan lipid. Pada penelitian ini dilakukan ekstraksi lipid rumput laut (makroalga) Ulva fasciata berdasarkan metode Folch dengan menggunakan sokhlet dan campuran pelarut yang digunakan yaitu kloroform:metanol (2:1/ (v/v)). Hasil ekstraksi lipid Ulva fasciata menghasilkan dua fasa yaitu fasa kloroform sebanyak 0,6 % (v/b) dan fasa metanol sebanyak 7,79 % (v/b). Selanjutnya kedua fasa ekstrak kasar lipid Ulva fasciata tersebut diuji aktivitas antibakterinya terhadap bakteri Bacillus cereus sebanyak tiga kali pengulangan. Kontrol positif yang digunakan adalah tetrasiklin dan kontrol negatifnya adalah pelarut yaitu kloroform dan metanol. Hasil penelitian menunjukkan bahwa kedua fasa tersebut memberikan aktivitas antibakteri sebesar 0,02 mm/ μg ekstrak untuk fasa klorofrom dan 0,08 mm/ μg ekstrak untuk fasa metanol.
