Problem-Based Learning as a Learning Innovation Strategy To Improve the Motivation and Learning Outcomes of Distance Learning

Distance learning, which lasted long during the COVID-19 emergency, has led to student boredom in participating in the learning process. The impact is a decrease in learning outcomes, so innovative learning methods are needed to minimize this. This study will analyze the application of problem-based learning by considering learning outcomes and student motivation. The subjects of this study were 5th-semester Mechanical Engineering students. The design of this study used classroom action using the Kemmis and McTaggart models, which consisted of three steps: planning, acting and observing, reflecting, and carried out in two cycles. The research data was then analyzed quantitatively based on predetermined indicators. Based on this research study, it was found that learning outcomes data increased by 36% from cycle I to cycle II. The results of student learning motivation in Process I were 27.3% had high learning cycles, 63.7% had moderate learning cycles, and 9.9%. In cycle II, students' learning motivation increased from high, medium, and low, respectively, by 45%, 52%, and 3%. Based on the results of the analysis, this means that problem-based learning strategies improve learning outcomes and student learning motivation.Pembelajaran jarak jauh merupakan salah satu kebijakan pendidikan selama masa darurat COVID-19. Hal ini dilakukan sebagai upaya untuk menjaga proses pendidikan agar tidak berhenti meski dalam suasana pandemi. Namun, pembelajaran jarak jauh yang telah berlangsung cukup lama juga menimbulkan masalah. Kejenuhan peserta didik dalam mengikuti proses pembelajaran akan berdampak pada penurunan hasil belajar, sehingga diperlukan metode pembelajaran yang inovatif untuk meminimalisir hal tersebut. salah satunya dengan menerapkan problem based learning. Penelitian ini akan menganalisis bagaimana menerapkan pembelajaran berbasis masalah dengan mempertimbangkan hasil dan motivasi belajar siswa. Desain penelitian ini menggunakan tindakan kelas menggunakan model Kemmis dan McTaggart yang terdiri dari tiga langkah, yaitu: merencanakan, bertindak dan mengamati, merefleksikan yang dilakukan dalam dua siklus. Data penelitian kemudian dianalisis secara kuantitatif berdasarkan indikator yang telah ditentukan. Berdasarkan penelitian ini, ditemukan bahwa penerapan pembelajaran jarak jauh dengan metode pembelajaran berbasis masalah dapat meningkatkan hasil belajar siswa di masa pandemi COVID-19 dan meminimalisir kebosanan siswa yang menyebabkan rendahnya motivasi peserta didik. Data hasil belajar meningkat sebesar 36% dari siklus I ke siklus II. Hasil motivasi belajar siswa pada siklus I adalah 27,3% siswa yang memiliki siklus belajar tinggi, 63,7% memiliki siklus belajar sedang dan 9,9%. Pada siklus II, motivasi belajar siswa meningkat dari tinggi, sedang dan rendah masing-masing sebesar 45%, 52%, dan 3%

Perempuan Bima dan Strategi Adaptasi Pasca Bencana Banjir Bandang (Studi Kasus Peran Perempuan di Kabupaten Bima, NTB)

The research titled “Bima\u27s Women and Post Disaster Mitigation Adaption Strategy for flash floods (Case Study of Women in Maintaining family Economics After The Flash Floods Disaster in Bima)” Takes place in Nisa Village, Woha Subdistrict, Bima District. By doing this research, the researcher are expected to be able to: (1) knowing in depth the adaptive strategy done by women in reconstructing their social life after flash floods disaster, (2) knowing the change of life after flash floods, (3) knowing the obstacles faced by women in the implementation post flash floods adaptive strategy. This research uses explorative qualitative research method. The research location is located in Nisa Village, Woha District, Bima District, West Nusa Tenggara Province. The subjects of this study were women housewives and Nisa village apparatus. Data were collected through interviews and observations to collect information on adavtive strategies, changes in post-flash floods life, and the constraints faced by women in implementing adaptive strategies after the flash floods disaster. Further data analysis by performing several stages that include data collection, data classification, interpretation to the writing of research reports. The results of this research show that (i) Nisa village women experiencing changes in economic, social and cultural life after the disaster flash floods. (ii) adaptive strategies implemented by Nisa village women in sustaining their household economies, among others, by active strategies in the form of exploiting natural resources and human resources from close relatives, extending working hours, and working to reduce family economic expenditure. The network strategy undertaken by Nisa village women is by owing the banks and neighbors. (iii) the constraints faced by women in Nisa village in carrying out an effective strategy are the loss of some natural resources that can support economic recovery , large losses due to flood disaster become an obstacle in economic recovery, and lack of acces to village economic institutions

Keberhasilan Inseminasi Buatan Menggunakan Semen Beku Dan Semen Cair Pada Sapi Peranakan Ongole

The purpose of this research was to know about the successfully artificial insemination (AI) using frozen and liquid semen of Ongole cross (PO) cattle indicated by Service per Conception (S/C), Days Open (DO) dan Conception Rate (CR). The materials used were 60 heads of Ongole crossbred cattle which were selected purposively using some criteria, such as having calving experience, healthy, and free from any reproduction disorder. This field experiment consisted of direct observation and interview to acquire primary and secondary data. Datas were analyzed descriptively and continued by a paired t-test. The results showed that the value of (S/C) was very significantly different (P<0.01), DO was not significantly different (P>0.05). CR for P1, P2, P3, and P4 was found 63.33% , 86.67%, 16.33%, 83.33% respectively. The conclusion of this research was AI using frozen and liquid semen with only 5 days preservation had a difference on the value of service per conception. The most successfull AI was found higher in the liquid semen which was stored for 1 and 5 days than that of frozen semen

Analisa Proses Perpindahan Panas Konveksi Pada Mesin Pengering Rempah-Rempah Otomatis

Perkembangan ilmu pengetahuan dan teknologi saat ini dibutuhkan untuk memberikan solusi yang tepat dari permasalahan yang ada, terutama dalam bidang industri. Saat ini penggunaan teknologi pada industri makanan dan minuman telah berkembang begitu pesat. Inovasi mesin-mesin produksi mulai bermunculan dengan tujuan agar proses produksi lebih efektif dan efisien. Bahan dari mesin produksi berbasis foodgrade menjadi suatu hal penting jika dikaitkan dengan proses produksi makanan dan minuman, salah satunya adalah stainless steel, selain telah memenuhi standart foodgrade, stailess steel juga merupakan bahan dengan penghantar kalor yang baik. Fokus pada penelitian ini adalah  menganalisa perpindahan panas konveksi pada mesin pengering rempah-rempah otomatis, mesin ini digunakan dalam proses produksi jamu. Uji coba mesin pengering otomatis menggunakan beban yang berupa rempah- rempah seberat 10 kg. Pengambilan data pada proses uji coba dilakukan selama 2 jam. Dimulai saat pertama kali mesin dinyalakan dan kontrol suhu diaktifkan dengan batasan suhu maksimal 70℃. Berdasarkan hasil eksperimen diperoleh bahwa energi yang dibutuhkan mesin agar bisa mencapai suhu 68°C adalah 2.428,2 KJ
