Sistem propulsi kapal adalah suatu mekanisme yang akan memutar baling-baling. Pada perkembangan saat ini motor induksi 3 fasa banyak digunakan untuk kendaraan elektrik baik untuk mobil listrik maupun propulsi pada kapal. Disamping keunggulannya motor induksi memiliki kelemahan yaitu sulitnya mengatur kecepatan motor induksi dikarenakan sifatnya yang tidak linier. Pada prinsipnya motor induksi dioperasikan pada kecepatan yang konstan, bila beban berubah kecepatan motor juga berubah. Dari permasalahan tersebut dalam penelitian ini dirancang alat kendali kecepatan motor berbasisi logika fuzzy untuk sistem propulsi elektrik pada kapal menggunakan pulse width modulation. Untuk mengetahui kinerja alat maka dilakukan beberapa pengujian, pengujian pertama dengan membandingkan respon kecepatan motor mengguakan logika fuzzy dan tanpa logika fuzzy dimana hasilnya adalah untuk respon kecepatan motor tanpa menggunakan kontrol logika fuzzy rata-rata dapat menempuh 23 detik untuk stady state, sedangkan untuk penggunaan kontrol logika fuzzy rata-rata mampu mencapai stady state dengan waktu 17 detik. Untuk nilai rata-rata error stady state tanpa penggunaan kontrol logika fuzzy yaitu sebanyak 97 rpm, sedangkan untuk penggunaan kontrol logika fuzzy rata-rata nilai error stady state adalah 78 rpm. Dimana untuk rise time sendiri tanpa menggunakan logika fuzzy rata-rata adalah 4 detik dan untuk penggunaan kontrol logika fuzzy memerlukan waktu rata-rata 2 detik.

The newest component of the independent curriculum is the Pancasila student profile. In terms of character education and increasing student competence, the Pancasila student profile is a reference for educational policy guidelines. One of the problems with literacy skills at Al-Muawanah Islamic Elementary School in Surabaya is that the majority of grade 1 students' literacy skills are still below standard. Some children still have difficulty distinguishing letters; when reading, there are words that are missing or even incomplete, and students' understanding of reading material is also below standard. Research and development use a model adapted by Borg and Gall. Of the ten development steps, researchers only implemented seven. The results of this development show: 1) The module specifications consist of a cover, introductory remarks, table of contents, materials, evaluation questions, and author biodata. The results of the research were 90.6% content experts with good qualifications, 89.3% learning media experts with good qualifications, and 94.6% learning experts with good qualifications. 2) To determine the attractiveness of the module, the researcher conducted a post-test in class on 10 students with an achievement percentage of 91.8% and very good qualifications. This shows that the use of the big book has met the criteria of being attractive and valid. Data analysis used the Paired Samples T Test with SPSS 16 tools, and the results were Sig 0.000 < 0.02, so Ho was rejected, meaning that there were differences in learning outcomes between students who had used the big book. So it can be concluded that the use of big books is able to improve literacy skills based on the Pancasila student profile..

Background: The waste problem is increasingly complicated in various cities, including Makassar City which is the tenth largest city in Indonesia according to its population, which is 1,449,401 people. Makassar City only has one final disposal site, namely TPA Tamangapa. The percentage of waste volume at TPA Tamangapa which is managed using the Open Dumping method is dominated by organic food waste, which is 38.82%, so the smell and ammonia gas evaporates in the air. Acute effects due to exposure to ammonia at a concentration of 400-700 ppm can cause irritation to the respiratory tract, nose, throat and eyes. Aim: The purpose of this study was to determine the concentration of NH3 in ambient air and the health problems of scavengers at TPA Tamangapa. Method: This type of research is quantitative research with a descriptive approach. Data collection was carried out using a questionnaire of 177 respondents and direct measurement of ambient air using an impinger at TPA Tamangapa in 5 zones. Methods of data analysis using univariate test. . Results: The results showed that the highest ambient air NH3 concentration occurred at night, which was 7.22 mg3/m3, in zone 4, where scavengers live, and the lowest during the day, which was 0.01 mg3/m3, was in zone 5, where the pemlung weighed the waste that had been sorted beforehand. The most health problems were first coughing around 134 people, second was skin irritation around 86 people and third was eye irritation as many as 70 people but there were around 7 people who experienced coughing up blood, these seven people had been scavengers for years. This research requires special attention from the puskesmas in their working area to provide free health services to scavengers because most do not have BPJS cards so if they are sick they do not go for treatment. Conclusion: The concentration NH3 become pollution in the zona 1, 3 and 5, and and the highest disease suffered by scavengers is coughing, skin irritation and also eye irritation.

Nyeri punggung bawah adalah rasa tidak nyaman atau rasa sakit yang terjadi di daerah punggung bagian bawah tubuh. Nyeri punggung bawah seringkali terkait dengan gangguan pada jaringan lunak seperti otot, tendon, ligamen, serta sendi, dan juga dapat mempengaruhi sistem saraf. Tujuan dari penelitian ini adalah untuk mengevaluasi hubungan antara faktor usia, indeks massa tubuh, masa kerja, dan beban kerja dengan keluhan Low Back Pain pada Tenaga Kerja Bongkar Muat di PT. Pelindo IV (Persero) Cabang Ambon. Penelitian ini menggunakan pendekatan kuantitatif dan desain penelitian cross sectional. Populasi yang terdiri dari 400 tenaga kerja bongkar muat dipilih secara acak menggunakan metode simple random sampling, dengan sampel sebanyak 197 orang. Analisis data meliputi analisis univariat dan analisis bivariat dengan menggunakan uji chi-square. Hasil penelitian akan disajikan dalam bentuk tabel distribusi frekuensi dan narasi interpretasi. Hasil penelitian menunjukkan adanya hubungan yang signifikan antara usia (p=0,00<0,05), indeks massa tubuh (p=0,008<0,05), dan masa kerja (p=0,00<0,05) dengan keluhan LBP pada TKMB. Namun, tidak ditemukan hubungan yang signifikan antara beban kerja (p=0,284>0,05) dengan keluhan LBP. Selain itu, faktor lain yang mungkin berkontribusi terhadap keluhan LBP adalah beratnya beban atau barang yang diangkat oleh para pekerja. Temuan ini memiliki implikasi penting dalam pengembangan strategi pencegahan dan peningkatan kesejahteraan TKMB di industri tersebut. Diharapkan agar penelitian selanjutnya untuk beberapa referensi dengan memiliki kaitan erat dengan kecelakaan kerja.
