Abstract

This research is based on the background of the low mathematical problem solving abilities due to less effective learning, especially lack of lesson hours. Blended learning is a two-way learning model namely face-to-face learning and online learning, while E-learning is a face-to-face learning model. The blended learning and e-learning learning model requires online media such as Edmodo. Efforts to address these problems, researchers aim to determine the effect of these two learning on improving mathematical problem solving abilities. The research method used in this study uses quasi-experimental methods (Quasy experimental design) with the type of research used is the pretest-posttest control group design. The data collection technique uses a randomized class technique, where the population is all eighth grade students of SMP N 21 Bandar Lampung. The hypothesis test used is gain-test with analysis techniques using one way ANOVA. From the results of the study, blended learning and e-learning using edmodo there was an increase in mathematical problem solving skills with moderate levels of calcification.

Abstract

Utilization of agro-industrial waste such as corn stover can be a solution for farmers. Corn stover has good nutritional content and provides economic benefits to farmers in terms of easy and cost-effective corn cultivation. The aim of this research was to evaluate the quality of corn silage based on different fermentation times. This study employed an experimental approach using a Completely Randomized Design (CRD) with 4 treatments and 3 replications. The quality analysis was conducted through proximate analysis to measure the moisture and ash content of corn silage. The fermentation process was carried out on corn plants with different fermentation durations, namely 14, 21, 28, and 35 days. The quality data of silage, including proximate analysis, were analyzed using one-way ANOVA with SPSS 24 software. The research results indicate that the fermentation time using effective microorganisms-4 (EM-4) has an impact on the quality of corn silage as livestock feed, showing the highest improvement during a 14-day fermentation period in terms of protein, fiber, and fat content. However, this silage has a relatively lower carbohydrate content compared to other treatmentsAbstrakPemanfaatan limbah agroindustri seperti tebon jagung dapat menjadi solusi bagi peternak. Tebon jagung memiliki kandungan nutrisi yang baik dan memberikan manfaat ekonomis bagi peternak dalam hal pemeliharaan tanaman jagung yang mudah dan hemat. Tujuan dari penelitian ini adalah untuk mengevaluasi kualitas silase jagung berdasarkan variasi waktu fermentasi. Penelitian ini menggunakan pendekatan eksperimental dengan Rancangan Acak Lengkap (RAL) terdiri dari 4 perlakuan dan 3 pengulangan. Analisis kualitas dilakukan dengan uji proksimat untuk mengukur kandungan air dan kandungan abu dalam silase jagung. Proses fermentasi dilakukan pada tanaman jagung dengan durasi fermentasi yang berbeda, yaitu 14, 21, 28, dan 35 hari. Data kualitas silase berupa uji proximat dianalisis menggunakan uji one-way ANOVA dengan menggunakan perangkat lunak SPSS 24. Hasil penelitian memperlihatkan pengaruh waktu fermentasi dengan penggunaan effective microorganisms-4 (EM-4) terhadap kualitas silase jagung sebagai pakan ternak menunjukkan adanya peningkatan tertinggi pada waktu fermentasi selama 14 hari dalam hal kandungan protein, serat, dan lemak. Namun, silase tersebut memiliki kandungan karbohidrat yang cukup rendah dibandingkan dengan perlakuan lainnya

Abstract

Red dragon fruit peel waste is a potential source for making bioethanol because it contains carbohydrates in the form of cellulose. The bioethanol production process involves several stages, including pretreatment, delignification, hydrolysis, fermentation and distillation. The aim of this research is to analyze variations in the amount of bread yeast (Saccharomyces cerevisae) on the amount of bioethanol produced. This research used variations in the amount of bread yeast (Yeast Saccharomyces cerevisiae) of 10%, 15%, and 20%, as well as fermentation times of 1 day (24 hours), 2 days (48 hours), and 3 days (72 hours). Qualitative testing of hydrolysis results is carried out through phytochemical tests using the Benedict and Molish tests, while quantitative testing of distillation results uses an alcohol meter to determine the level of bioethanol produced from the fermentation process. Qualitative test results showed positive results in the hydrolysis of red dragon fruit skin, indicated by color changes in the Benedict and Molish tests. Quantitative tests using an alcohol meter produced the highest bioethanol content of 6% from a bread yeast volume of 20% in day two fermentation. These results indicate that the optimum fermentation time is on the second day, where bioethanol production reaches its peak.ABSTRAK  Limbah kulit buah naga merah merupakan salah satu sumber yang potensial untuk dijadikan bioetanol karena mengandung karbohidrat dalam bentuk selulosa. Proses pembuatan bioetanol melibatkan beberapa tahap, termasuk pretreatment, delignifikasi, hidrolisis, fermentasi, dan destilasi. Tujuan dari penelitian ini adalah untuk menganalisis variasi penambahan jumlah ragi roti (Yeast Saccharomyces cerevisae) terhadap jumlah bioetanol yang dihasilkan. Penelitian ini menggunakan variasi jumlah ragi roti (Saccharomyces cerevisiae) sebanyak 10%, 15%, dan 20%, serta lama waktu fermentasi selama 1 hari (24 jam), 2 hari (48 jam), dan 3 hari (72 jam). Uji kualitatif hasil hidrolisis dilakukan melalui uji fitokimia menggunakan uji benedict dan molish, sementara uji kuantitatif hasil destilasi menggunakan alkohol meter untuk menentukan kadar bioetanol yang dihasilkan dari proses fermentasi. Hasil uji kualitatif menunjukkan adanya hasil yang positif dalam hidrolisis kulit buah naga merah, ditunjukkan oleh perubahan warna pada uji benedict dan molish. Uji kuantitatif menggunakan alkohol meter menghasilkan kadar bioetanol tertinggi sebesar 6% dari volume ragi roti sebanyak 20%, dengan lama fermentasi 2 hari. Hasil ini menunjukkan bahwa waktu fermentasi optimum adalah pada hari kedua, di mana produksi biobioetanol mencapai puncaknya.

Penelitian ini bertujuan untuk mendeskripsikan kemampuan literasi matematis siswa dengan menggunakan model pembelajaran Direct Instruction, serta mengidentifikasi faktor-faktor yang memengaruhi kemampuan tersebut. Penelitian ini menggunakan pendekatan kualitatif dengan jenis studi kasus. Subjek dalam penelitian ini adalah siswa kelas XI TJKT 2 SMK Negeri 1 Bandar Lampung yang dipilih menggunakan teknik purposive sampling, yaitu 6 subjek penelitian dengan 2 siswa kategori tinggi, 2 siswa kategori sedang, dan 2 siswa kategori rendah. Teknik pengumpulan data yang digunakan meliputi, tes kemampuan literasi matematis, wawancara dan observasi. Triangulasi pada penelitian ini yaitu menggunakan triangulasi teknik. Hasil penelitian menunjukkan bahwa setelah penerapan model Direct Instruction, 87% siswa berada pada kategori literasi matematis sedang, 6,5% tinggi, dan 6,5% rendah. Siswa kategori tinggi menguasai aspek merumuskan, menggunakan, dan menafsirkan, sedangkan kategori sedang dan rendah masih lemah pada interpretasi hasil. Faktor pendukung meliputi pembelajaran terstruktur, umpan balik guru, dan contoh soal aplikatif, sedangkan hambatan mencakup partisipasi pasif, ketergantungan pada contoh, serta lemahnya komunikasi matematis.
