Prediksi tingkat kenyamanan termal Kota Pontianak berdasarkan nilai Temperature Humidity Index (THI) telah dilakukan menggunakan jaringan syaraf tiruan propagasi balik (JSTPB). Data bulanan kelembapan dan suhu udara pada tahun 2009 hingga 2018 digunakan sebagai masukan bagi proses pelatihan jaringan, sementara proses validasi menggunakan data bulanan unsur udara yang sama pada tahun 2019. Arsitektur jaringan yang digunakan untuk unsur kelembapan udara adalah 12 lapisan masukan, 40 lapisan tersembunyi, dan 1 (satu) lapisan keluaran, sementara untuk suhu udara terdiri dari 12 lapisan masukan, 30 lapisan tersembunyi dan 1 (satu) lapisan keluaran. Jaringan yang dibentuk menghasilkan koefisien korelasi kelembapan udara dan suhu udara masing-masing sebesar 0,90 dan 0,91 dan diklasifikasikan sebagai berkorelasi sangat kuat. Nilai THI rata – rata tahunan yang dihitung menggunakan data-data unsur udara tersebut adalah 24,83℃. Hasil tersebut menunjukkan bahwa secara rata-rata 50% populasi warga di Kota Pontianak merasakan kondisi termal yang nyaman. Terdapat beberapa bulan yang menunjukkan sebanyak 100% populasi merasakan hal yang sama, yaitu pada bulan Juni, Agustus, Oktober, dan Desember.

A large-scale field experiment tested psychological interventions to reduce engine idling at long-wait stops. Messages based on theories of normative influence, outcome efficacy, and self-regulation were displayed approaching railway crossing on street poles. Observers coded whether drivers (N = 6,049) turned off their engine while waiting at the railway crossings (only 27.2% did so at baseline). Automatic air quality monitors recorded levels of pollutants during barrier down times. To different degrees, the social norm and outcome efficacy messages successfully increased the proportion of drivers who turned off their engines (by 42% and 25%, respectively) and significantly reduced concentrations of atmospheric particulate matter (PM2.5) two meters above ground level. Thus, the environment was improved through behavior change. Moreover, of both theoretical and practical significance there was an 'accelerator effect', in line with theories of normative influence whereby the social norm message was increasingly effective as the volume of traffic increased.

This study aimed to determine the procedures and quality of developing test instruments to measure student mathematical communication skills of SMP Negeri 17 Makassar. The research type used research and development with the Plomp model through 4 stages: preliminary investigation, design, realization/construction, test, evaluation, and revision. The results showed that the developed test instrument was valid with a high interpretation from the value of CVR and CVI is 1. The instrument test was reliable on 0.71 with a very high interpretation while in terms of the level there was 1 item in the difficult category, 7 items in the medium category and 1 item in the easy category. In terms of distinguishing power, there were 2 items at sufficient categories, 3 items in the good category, 2 items in very good categories and 2 items in the poor category. Therefore, the test instruments that met the quality of the criteria from the good test instruments consists of 5 items of description questions. Moreover, based on the results of the trial, it is known that from 32 students there were 4 students categorized who had a very good level of mathematical communication skills, 9 students included in the good level of mathematical communication skills, 17 students under sufficient level of mathematical communication skills, and 2 students in the less level of mathematical communication skills.
