Higher-order thinking skills critical to being applied and developed in learning. Because the learning activity is focused on the higher-order thinking skills development, then learning activities will be more influential, effective, and efficient, so that the intellectual abilities of teachers and students become more skilled, it positively will affect the increase in the quality of education. There is a gap in students' critical thinking ability based on the pre-research survey results. The basic level of thinking is in the poor category, and self-efficacy is still lacking. This study aims to determine the extent to which the application of higher-order thinking skills learning through the problem-based learning (PBL) model improves student's critical thinking and self-efficacy. This study uses a quasi-experimental design and data collection techniques in tests, questionnaires, and observation sheets. This study's population was 123 students, sampling using a convenience sampling technique so that the sample used was 62 students. Based on the research results, there are differences. There is an increase between students' critical thinking skills and self-efficacy who use the PBL model rather than the conventional model. The research result implies that the PBL model is highly recommended for economics teachers. Still, it is necessary to provide innovation in the learning model so that in the learning process, it uses one model and innovates with other models.
Abstrak. Ketersediaan air bersih sangat penting dikarenakan hampir seluruh aktivitas manusia sangat bergantung terhadap ketersediaan air bersih. Hal ini membuat faktor produksi dan ketersediaan air bersih selalu menjadi prioritas dalam pelayanan penyaluran air bersih sehingga penulis tertarik untuk mengkaji tentang peramalan jumlah penggunaan air bersih di PDAM Kota Makassar. Salah satu metode yang cocok untuk menangani kasus tersebut adalah metode Time Series. Metode Triple Exponential Smoothing atau biasa disebut dengan Winter Exponential Smoothing merupakan salah satu metode Time Series yang cocok untuk menangani data yang bersifat musiman seperti jumlah penggunaan air bersih di Kota Makassar. Adapun Langkah analisis dari metode Triple Exponential Smoothing adalah identifikasi model, estimasi parameter dengan trial and error, selanjutnya adalah perhitungan nilai awal dari pemulusan data, trend, dan musiman dengan panjang satu musim L=12 dan yang terakhir adalah menghitung nilai error dengan menggunakan MAPE dan RMSE. Model terbaik diperoleh dari kombinasi parameter α = 0,1; β = 0,1; dan γ=0,6 yang menghasilkan kesalahan peramalan terkecil menggunakan RMSE dengan nilai sebesar 168,175 dan MAPE dengan nilai sebesar 4,736. Dengan meggunakan model maka diperoleh peramalan jumlah penggunaan air bersih di PDAM Kota Makassar dari bulan januari – desember 2019 sebagai berikut: 2779,10; 2788,94; 2728,61; 2797,48; 2787,97; 2752,66; 2742,18; 2708,50; 2644,55; 2521,50; 2537,74; 2732,55. Dari hasil peramalan tersebut terlihat mendekati dan tidak terlalu jauh menyimpang dari data tahun sebelumnya sehingga dapat dijadikan acuan produktivitas air bersih di PDAM Kota Makassar agar produktivitas air dapat mencukupi semua kebutuhan masyarakat di Kota Makassar.Kata kunci: air, triple exponential smoothing, time series, peramalan.

The use of pesticides that are not completely on target creates residues and has a negative impact on health and the environment. The lack of guidance from stakeholders and the lack of knowledge about the dangers of pesticides cause farmers to ignore the risks of excessive use of pesticides. Preventive efforts are needed to reduce the impact of pesticide use, so that the policy brief could be prepared as an effort to minimize the impact of pesticide use through more effective policy recommendations that is to be addressed to local governments and related agencies. This research used a qualitative approach. The sample in this study consisting of the community health centre officers, the Health Service and the Agriculture Service. Stakeholder perceptions in policy making were influenced by knowledge factors, family background factors and need factors. The policy brief was prepared based on the results of interviews and focus group discussions with informants relating to the impact of and the prevention of the use of pesticides excessive. The stages of preparing a policy brief start from determining the problem and audience, creating a policy framework, writing an executive summary and reviewing the results of the policy brief. Perception stakeholders for developing the use of pesticides to have not run optimally even though we already be a job and the program as a clear. The need for monitoring and evaluation counseling and flanking by stakeholders to farmers periodically 6 months.
Perekam medis dalam bekerja tidak hanya sekedar menjalankan tugas dan kewajibannya saja, namun mereka juga membutuhkan motivasi. Motivasi yang baik diharapkan mampu mendorong para perekam medis untuk menghasilkan kinerja yang baik pula dalam melaksanakan tugasnya. Survey awal di RSUD Ungaran menunujukkan bahwa penghargaan atau apresiasi terhadap prestasi pegawai masih kurang, sehingga hal ini menyebabkan para pegawai menjadi kurang termotivasi. Tujuan penelitian ini yaitu untuk mengetahui faktor motivasi kerja perekam medis dan informasi kesehatan di RSUD Ungaran, dilihat dari karakteristik, faktor ektrinsik dan instrinsik. Metode penelitian yang digunakan adalah metode deskriptif yaitu menggambarkan sebuah kejadian yang diteliti, dengan pendekatan kuantitatif yaitu yang diartikan sebagai metode penelitian yang bersifat positivisme. Populasi yang digunakan dalam penelitian ini adalah seluruh petugas rekam medis. Sebanyak 21 lembar kuesioner diberikan kepada seluruh responden dan tersisa satu karena responden sedang dalam masa cuti. Hasil yang didapat adalah rata-rata faktor intrinsik mencapai 76.25% dan faktor ekstrinsik sebanyak 78.13%, karakteristik umur petugas rata-rata 41-65 tahun, masa kerja 18-40 tahun, pendidikan terakhir DIII Rekam Medis sebanyak 7 orang. Indikator paling tinggi adalah Pekerjaan itu sendiri (87.5%) dan hubungan intrapersonal (97.5%). Saran dari kami agar diberikan apresiasi atau penghargaan kepada pegawai minimal dalam bentuk ucapan selamat. Dan sebaiknya dilakukan perbaikan fasilitas SIMRS dengan segera agar para petugas rekam medis menjadi lebih semangat dalam bekerja. Diperlukan juga pemberian pelatihan atau pendidikan lanjutan bagi pegawai rekam medis yang bukan merupakan lulusan dari DIII Rekam Medis.
