Deteksi Daging Babi Pada Produk Bakso di Pusat Kota Salatiga Menggunakan Teknik Polymerase Chain Reaction

Abstract: Teknik PCR mempunyai kemampuan yang sensitif untuk deteksi keberadaan daging babi di dalam daging segar maupun produk olahan yang dicampur dengan bahan lain. Tujuan penelitian ini untuk mengetahui apakah produk bakso yang dijajakan di pusat kota Salatiga mengandung daging babi. Teknik stratified random sampling digunakan untuk mengambil sampel bakso yang dijajakan 13 warung bakso dari 25 warung bakso yang tersebar di pusat Kota Salatiga. Isolasi dan purifikasi DNA sampel bakso, daging sapi, dan daging babi menggunakan metode isolasi DNA jaringan hewan. DNA hasil isolasi dilanjutkan proses PCR menggunakan primer p14 untuk mengamplifikasi lokus PRE-1 pada genom babi. Proses amplifikasi DNA dengan program denaturasi awal pada suhu 93 °C selama 2 menit, diikuti 45 siklus terdiri atas denaturasi 93 °C selama 1 menit, annealing 62 °C selama 30 detik, ekstensi 72 °C selama 1 menit, kemudian diakhiri ekstensi 72 °C selama 2 menit. Produk PCR yang diharapkan muncul berukuran 481bp. Hasil elektroforesis gel agarose 1,2% pada produk PCR menunjukkan adanya pita DNA spesifik berukuran 481 bp pada daging babi dan sampel bakso nomor tiga belas, sehingga disimpulkan warung bakso nomor tiga belas produk baksonya mengandung daging babi. PCR technique has the ability to be sensitive to the detection of the presence of pork in fresh meat and processed products are mixed with other materials. The aim of this research to determine whether the product meatballs are sold in downtown Salatiga containing pork. Stratified random sampling technique is used to take samples of meatballs stall which sold 13 of the 25 meatballs stalls in the Salatiga City centre. Isolation and purification of DNA samples of meatballs, beef, and pork using DNA isolation method of animal tissue. DNA isolation results continue the process of PCR using primers to amplify p14 locus PRE-1 in the pig genome. DNA amplification process with initial denaturation program at a temperature of 93 °C for 2 min, followed by 45 cycles consisting of denaturation 93 °C for 1 min, annealing 62 °C for 30 seconds, extension 72 °C for 1 minute, then topped extension 72 °C for 2 minutes. PCR products were expected to appear sized 481bp. Results of a 1.2% agarose gel electrophoresis of PCR products indicate a specific DNA band sized 481 bp on pork and meatball sample number thirteen, so it concluded meatball stall number thirteen baksonya products containing pork.

Pengembangan perangkat pembelajaran fisika berbasis life skill untuk meningkatkan minat kewirausahaan siswa

Abstract: Penelitian ini bertujuan mengembangkan perangkat pembelajaran berbasis life skill untuk meningkatkan minat kewirausahaansiswa. Penelitian dilatarbelakangi oleh tingginya jumlah lulusan SLTA yang tidak melanjutkan studi ke Pendidikan Tinggi sertaterbatasnya perangkat pembelajaran berbasis life skill. Hasil penelitian menunjukan ada perbedaan minat kewirausahaan. kelaseksperimen memiliki minat yang lebih tinggi (85,61) dibanding kelas kontrol (62,19). Hasil lain menunjukan adanya hubunganyang kuat antara kecapakan hidup dengan minat kewirausahaan siswa.Hasil penelitian menunjukkan bahwa penggunaanperangkat pembelajaran fisika berbasis life skill dapat meningkatkan minat kewirausahaan siswa. Perangkat pembelajaran selainmampu meningkatkan minat kewirausahaan juga tidak menurunkan rata-rata nilai siswa, karena rata-rata nilai masih di atasstandar ketuntasan yaitu 76. Â This study is performed with the background of the lack of life skill based learning equipments and the huge number of SHSgraduate student who do not apply to the higher level of education and the aim of developing life skill based learning equipments toincrease entrepreneurship interest of the student. The result of the study shows that there is a different interest of entrepreneurshipbetween experiment and control group. It also shows that there is a close relationship between life skill and entrepreneurshipinterest of the student. This interest can be increased through the use of the developed life skill based learning equipments. Keywords : Lifeskill; entrepreneurship, learning equipments

Preliminary Analysis of Assessment Instrument Design to Reveal Science Generic Skill and Chemistry Literacy

Abstract: The purpose of this research is to design assessment instrument to evaluate science generic skill (SGS) achievement and chemistry literacy in ethnoscience-integrated chemistry learning. The steps of tool designing refers to Plomp models including 1) Investigation Phase (Prelimenary Investigation); 2) Designing Phase (Design); 3) Construction/Realization Phase (Realization/Construction) ; 4) Test, Evaluation and Revision Phase. (Test, Evaluation and Revision). To test the validity of assessment instrument, it was used content validity by three experts as validators, while to test the practical, it was used questionnaire which were given to 22 college students of food ingredients chemistry that is integrated of ethno-science and two supporting lecturers. The result of content validity showed that assessment tool which was developed was valid stated by experts with the reliability coefficient was 0,72. Every lecturers and 21 students gave positive response, so it can be concluded that developed assessment instrument was practice to use.

Decision Model for Saving Stocks Based on TPB and Financial Literacy

Abstract: This study investigated the behavior of investment decisions that were not only assumed on rationality but were also affected by other factors, such as psychological factors, one of which was financial literacy. There were so many causal studies of financial literacy and investment intentions. However, there were still issues of inclusion between studies. Therefore, this study adopted a theory of planned behavior, proposed as an explanatory model for investment intentions associated with financial literacy. By proposing attitude, subjective norms, and perceived behavioral control related to investment as a mediator of investment intention, the unit of analysis was students who were members of the capital market study group spreading across universities in Semarang. The sample used was 170 students conducted through a questionnaire survey, then analyzed descriptive statistics and SEM with the PLST Warp. The results showed that all variables, both attitudes, subjective norms, perceptions of behavioral control, significantly mediated the effect of financial literacy on investment intention in partial mediation. For future research, you can explore the variables of financial education as early predictors associated with this research model to get a holistic picture related to the effectiveness of student financial education.
