Indonesia mempunyai potensi rata-rata energi radiasi matahari global mencapai 4,5 hingga 5,5 kWh/m2/hari. Sehingga pemanfaat energi matahari dengan teknologi panel surya menjadi salah satu alternatif untuk mengatasi krisis energi. Penelitian ini bertujuan menganalisa pengaruh radiasi matahari dan temperatur panel terhadap performansi tipe panel surya mono dan polikristal kapasitas 100 Wp. Pengujian dilakukan selama dua hari di atas gedung Jurusan Teknik Mesin Politeknik Negeri Malang (7,944oLS ; 112,613oBT). Pengukuran data radiasi matahari, temperatur lingkungan, temperatur panel, tegangan dan arus keluaran panel dilakukan untuk mengetahui daya keluaran, efisiensi daya konversi panel dan Performance Ratio (PR) dari kedua panel tersebut. Hasilnya diketahui bahwa kenaikan temperatur permukaan panel surya berdampak pada penurunan daya keluaran panel. Untuk rata-rata radiasi matahari diatas 1000 W/m2 dengan rata-rata temperatur lingkungan 33 oC, maka untuk permukaan panel surya monokristal temperaturnya sekitar 30,6 oC terjadi kehilangan daya sebesar 2,3 %. Sedangkan pada panel polikristal, ketika temperatur permukaannya 47,5 oC terjadi kehilangan daya sekitar 10,12 %. Efisiensi konversi daya dari tipe monokristal adalah 11,90 %, dan tipe polikristal adalah 9,18 %. Sedangkan PR monokristal dan polikristal masing-masing adalah 0,63 dan 0,61. Sehingga untuk instalasi panel surya dalam penelitian ini performansi tipe monokristal lebih bagus daripada polikristal.

Pewarnaan pada permukaan aluminium oksida melalui proses anodisasi coloring diperlukan untuk memperbaiki estetika. Proses anodisasi coloring meliputi pembersihan, pembentukan pori-pori, pewarnaan dan penutupan pori-pori aluminium oksida. Proses pembersihan terdiri dari 8 langkah yang semuanya merupakan pembersihan kimiawi. Aluminium AA1100 dianodisasi dalam larutan asam sulfat kemudian diwarnai. Sebagai pewarna digunakan tinta printer (merk Exxxx) yang tersedia secara komersial. Hasil penelitian menunjukkan bahwa pada waktu anodisasi 30 menit, warna yang dihasilkan mempunyai kelekatan yang baik namun kurang merata dan cenderung tipis. Sedangkan pada waktu 45 menit, warna yang dihasilkan mempunyai kelekatan yang baik, dan merata yang cukup memadai. Karenanya waktu proses anodisasi harus lebih lama atau sama dengan 45 menit. Pengaruh kondisi anodisasi lainnya seperti konsentrasi asam sulfat dan rapat arus juga telah diteliti. Warna yang dihasilkan tinta printer pada oksida aluminium yang telah digunakan berulangkali dan mengalami pemanasan dan pendinginan menunjukkan warna yang setara dengan warna pada kondisi awal. Kondisi ini memunculkan dugaan bahwa tinta printer tersebut dapat dimanfaatkan sebagai pewarna aluminium oksida pada proses anodisasi coloring dan mempunyai stabilitas warna yang baik.

Pewarnaan secara anodisasi memberikan hasil yang menjanjikan pada permukaan aluminium. Cara ini mampu meningkatkan estetika dan mampu mengubah sifat permukaan. Proses anodisasi ini diselenggarakan melalui pembersihan, anodisasi, pewarnaan, dan penyegelan. Proses pembersihan permukaan menggunakan larutan NaOH, HCl, campuran larutan HNO3 dan H3PO4, dan air. Proses anodisasi dilangsungkan dalam larutan asam sulfat, dan proses pewarnaan menggunakan tinta printer komersial seperti biru, cyan, magenta, dan hitam, dan proses penyegelan menggunakan air panas. Hasil penelitian menunjukkan bahwa permukaan aluminium dapat diwarnai dengan baik oleh pewarna biru dan magenta pada rapat arus 0,01 A/cm2. Kemudian dipelajari pengaruh densitas arus yang meningkat dari 0,01 menjadi 0,03 A/cm2. Pada penggunaan pewarna biru dan cyan, pada rapat arus yang lebih tinggi diperoleh kualitas dan distribusi warna yang lebih baik. Pada pewarna magenta dan hitam, kualitas warna dan distribusi yang baik diperoleh pada kerapatan arus yang rendah. Hal ini menunjukkan dengan jelas bahwa kemampuan permukaan aluminium untuk diwarnai oleh tinta komersial berbeda-beda antar jenis warna dan bergantung pada rapat arus yang digunakan. Lebih lanjut dipelajari pengaruh rapat arus terhadap konduktivitas permukaan aluminium.

Bioethanol is an alternative fuel to substitute fossil oil. Bioethanol has several advantages in its use as a fuel in addition to its renewable nature, and bioethanol is also believed to reduce some motor vehicle emissions. The purpose and objective of this study were to determine the effect of a mixture of Bioethanol and Pertamax on gas emissions in a 4-stroke motor with variations in the fuel mixture and engine cycle. This test method is carried out with the measurement parameters of CO, HC, CO2, and O2. Tests on motor vehicles were carried out with variations of BP0 (0% Bioethanol) to BP100 (100% Bioethanol). The test results using a gas analyzer and analyzed using excel show that bioethanol cannot reduce exhaust gas emissions. Adding bioethanol fuel to Pertamax can also increase the fuel's octane number (RON) and specific gravity. From the available data, adding bioethanol can reduce HC emission levels by up to 4ppm at BP50 at 6000 rpm, increasing CO2 emissions by 13.4% at BP50 at 7000 rpm with a compression ratio of 13:1. For the lowest O2 emission level, it reaches 0.13%. at BP40 at 5000 rpm. CO emission levels are still relatively small in various mixtures with a yield of 0.01%, but at BP0 and BP80 at 13:1 compression, emissions tend to increase every rpm.

This research used the Peltier element as a car cabin cooler. This research aimed to compare the results of the lowest temperature produced by the Peltier element on the hot side. The design of this monitoring tool consists of LM35 as a temperature sensor and an electric velocity sensor to measure the velocity of the cooling fluid. Arduino Uno Microcontroller to control the system before being displayed to the LCD. The type of research used in this research is experimental research. In this study, variations in fluid flow velocity and type of cooling fluid were carried out. The fluid used is a mixture of water and water coolant with a ratio of 50%:50%. The results showed that the circulation of fluid cooling influences the temperature on the hot side of the Peltier. In cooling using water fluid, when the water pump rotates 4.5 liters/second, the temperature on the hot side of the Peltier is 36ᵒC. At the time of rotation of 13 liters/second, the temperature on the hot side of the Peltier is 32ᵒC. The difference between cooling using water fluid, water coolant, or a mixture of water and water coolant greatly affects the temperature produced on the cold side of the Peltier. In cooling using water, the lowest temperature produced reaches 8ᵒC. When the cooling using a fluid coolant, the lowest temperature reaches 6ᵒC. While cooling using a mixture of water and coolant, the lowest temperature reaches 3ᵒC. So it can be concluded that cooling using a mixture of water and water coolant is very effective compared to other fluid coolers.
