"Karies gigi merupakan penyakit gigi dengan prevalensi tertinggi di dunia. Saliva memiliki peran penting dalam melawan karies gigi dengan memproduksi nitrogen monoksida (NO) yang memiliki sifat antibakterial. Studi ini bertujuan untuk mengevaluasi kadar NO pada sampel saliva kelompok anak dan dewasa muda, hubungan antara kadar NO sampel saliva dengan karies gigi (DMF-T), hubungan antara pH dan kadar NO, serta membandingkan nilai rata-rata kadar NO pada sampel saliva dewasa muda dan anak-anak. Dalam studi cross-sectional, analisis dilakukan pada 20 sampel saliva anak dan dewasa muda dengan kaitannya pada indeks karies gigi (DMF-T) menggunakan uji Griess Reagent. Hasil uji menunjukkan bahwa tidak ada perbedaan signifikan dalam rata-rata kadar NO pada sampel saliva dewasa muda pada berbagai kategori DMF-T (p = 0,14). Korelasi antara kadar NO dewasa muda dengan DMF-T tidak signifikan (p = 0,797), begitu juga pada kelompok anak (p = 0,429). Uji korelasi antara pH dan kadar NO juga tidak menunjukkan hubungan yang signifikan (p = 0,629). Perbandingan rata-rata kadar NO antara sampel dewasa dan anak-anak tidak menunjukkan perbedaan yang signifikan (p = 0,794).

Dental caries is the most prevalent tooth disease globally. Saliva plays a crucial role in combating dental caries by producing nitric oxide (NO), known for its antibacterial properties. This study aims to assess NO levels in saliva samples from both children and young adults, examine the relationship between NO levels in saliva samples and dental caries (DMF-T), explore the correlation between pH and NO levels, and compare the average NO levels in saliva samples between young adults and children. In this cross-sectional study, the analysis involved 20 saliva samples from children and young adults, correlating them with the dental caries index (DMF-T) using the Griess Reagent test. The test results indicated no significant differences in the average NO levels in saliva samples from young adults across various DMF-T categories (p = 0.14). The correlation between NO levels in young adults and DMF-T was not significant (p = 0.797), and the same was observed in the children's group (p = 0.429). The correlation test between pH and NO levels also showed no significant relationship (p = 0.629). Furthermore, the comparison of average NO levels between adult and children's saliva samples revealed no significant differences (p = 0.794)."

"Seiring dengan meningkatnya populasi, maka kebutuhan akan sarana transportasi juga semakin meningkat. Untuk mengatasi hal tersebut diperlukan pengembangan kendaraan yang lebih efisien yaitu bisa bergerak cepat dan ramah lingkungan. Kendaraan surya merupakan alternatif sarana transportasi yang cukup popular saat ini. Berangkat dari permasalahan yang ada dan keinginan untuk mengikuti World Solar Challenge, maka penelitian ini bertujuan melakukan perancangan dan pengembangan sistem penggerak yang cocok untuk kendaraan surya, khususnya Brushless DC Permanent Magnet (BLDC PM) Motor, yang merupakan bagian dari keseluruhan kendaraan surya. Dimana motor listrik merubah energi listrik yang di dapat dari sumber tenaga menjadi energi mekanik yang dionkan untuk menggerakan kendaraan. Pengembangan yang dilakukan meliputi desain konsep, analisa teknik, pembuatan prototype, dan pengujian. Sehingga bisa dihasilkan suatu penggerak yang efisien, ringan, cukup handal, dan dapat berfungsi dengan baik.

The transport needs is becoming increasingly and more demanding in accordance with the population growth. In order to combat this, more efficient transportation vehicles need to be developed which are faster and cleaner. Solar electric vehicles are a popular transport alternative. Starts from the problem currently and the desire World Solar Challenge participating, this research aim to design and develop power train which is suitable for solar electric vehicles, especially a new hub mounted Brushless DC Permanent Magnet (BLDC PM) Motor, as part of solar electric vehicles. The electric motor converts the electrical energy from power supply to mechanical energy used to propel the vehicles. Development covered conceptual design, engineering analysis, making of prototype and testing. With the result that could produce a power train which efficient, lightweight, reliability and works properly."

"The following independent study paper will present an overview of the car industry in France(Europe) and South Korea (Asia) for the United States of America car industry. It will focusupon the historical background, and facts regarding several macroeconomic conditions, marketconditions and socio-cultural conditions. The author chose France and South Korea, becauseboth of them have appeared to have a good surface level for doing a foreign business for the UScar Industry to open up their new production there. This paper used a literature review based ongoogle scholars and the government's website. According to the Korea AutomobileManufacturers Association (KAMA) automobile output from Korea totaled 3,506.848 units in2020, down 11.2 percent from 2020. Despite the fall in production, the country's overall autooutput ranking moved up two notes from 2020. Car Production in France decreased to 1316371Units (1316,371 K Units) in 2020. The maximum volume was 3701870 Units and minimum was1316371 Units. Based upon the information gathered in this paper, South Korea has overallbetter conditions for US production and market seeking firms, compared to France, due to thehistorical background within the automotive industry, as well as the historical relations with theUnited States could support the choice for South Korea for investment opportunities, and so doesthe potential for future innovation capabilities of the region

"ABSTRAKDewasa ini perkembangan teknologi semakin pesat, orang lebih menuju padaotomatisasi sistem. Pada sistem perparkiran hanya baru dapat memberikan jumlahmobil didalam suatu lahan parkir, tetapi untuk menunjukan lahan parkir mana yangkosong belum tahu. Maka disini kami melakukan suatu percobaan sistem perparkiran,dimana alat ini memberikan informasi tentang jumlah dan lahan mana yang kosong .pada percobaan ini kami hanya membuat dalam sekala laboratorium agar kita tahudahulu bagaimana cara komunikasi dan memproses sensor tersebut yang nantinyadapat diterapkan dalam dunia nyata."
