Penelitian ini dilakukan dengan tujuan untuk mengetahui pengaruh variasi waktu pencelupan terhadap ketebalan dan kekerasan lapisan serta kekasaran permukaan pada proses pelapisan krom pada pelat titanium. Proses pelapisan dilakukan menggunakan larutan elektrolit dengan kandungan bahan krom 500 gr/ltr. Selama proses pelapisan, substrat titanium berperan sebagai katoda sedangkan timbal (Pb) berfungsi sebagai anoda. Parameter yang digunakan adalah waktu pencelupan yang terdiri dari 30, 45, 60 dan 75 menit. Pengukuran ketebalan lapisan dilakukan dengan menggunakan foto mikro sehingga ketebalannya dapat terlihat dengan jelas. Pengujian kekasaran permukaan dilakukan dengan pengujian SEM. Pengujian kekerasaan dilakukan dengan menggunakan uji kekerasan Vickers. Hasil uji SEM menunjukkan sebaran dan komposisi unsur pada permukaan dan substrat. Hasil uji foto mikro menunjukkan bahwa semakin lama waktu pencelupan maka lapisan krom yang terbentuk semakin tebal yaitu 18,532 Âµm setelah 75 menit. Hasil uji kekerasan pada substrat logam titanium sebesar 173,88 VHN, dengan bertambahnya waktu pencelupan maka kekerasan tertinggi pada waktu 75 menit sebesar 226,26 VHN. Hasil pengukuran kekasaran permukaan pada substrat titanium sebesar 0,251 Âµm. Berdasarkan hasil pengukuran, semakin lama waktu pencelupan maka tingkat kekerasan semakin menurun sebesar 0,221 Âµm setelah waktu 75 menit.Â

CCTV (Closed Circuit Television) adalah alat perekaman yang menggunakan satu atau lebih kamera video dan menghasilkan data video atau audio. CCTV adalah penggunaan video kamera yang mentransmisikan sinyal atau penyiaran tertuju kepada lingkup perangkat tertentu, yakni seperangkat monitor “spesifik terbatas”. CCTV (Closed Circuit Television) sudah menjadi alat pengawasan yang umum dipakai pada era sekarang ini, namun pengawasannya harus dilakukan dengan menggunakan perangkat yang bisa dipantau dengan komputer. Hal ini akan mengurangi tingkat pengawasan dikarenakan personal komputer membatasi ruang lingkup pengawas, sedangkan kebutuhan pengawas untuk melakukan mobilitas terkadang sulit dihindari. maka aplikasi untuk memantau CCTV akan sangat berguna untuk pemantauan situasi. Selain itu dengan CCTV kita hanya bisa memantau tanpa memberikan tindakan. Dalam mengatasi masalah tersebut maka dibutuhkanlah sebuah alat teknologi yang menggunakan sistem kendali Iot untuk menghasilkan sebuah pencegahan dalam hal ini dilakukan dengan menyalakan sebuah speaker. Alat yang ini dihubungkan koneksi internet ke CCTV dan CCTV dapat dilihat dari berbagai macam smartphon dan dari smartphone dapat menyalakan alaram pada daerah yang diberikan alaram.

This study aims to analyze the mechanical strength of composites with bamboo fiber and glass powder reinforcement using an epoxy matrix. The study used a hand lay-up method with three variations of volume fraction composition, namely (1) 15% bamboo fiber, 15% glass powder, 70% resin, (2) 20% bamboo fiber, 10% glass powder, 70% resin, and (3) 25% bamboo fiber, 5% glass powder, 70% resin. The bamboo fiber used was the result of alkali treatment using 15% NaOH solution to remove lignin and cellulose, while the glass powder was obtained from household glass waste with a particle size of 60 mesh. Mechanical property testing included tensile testing (ASTM D638 Type 1), compression testing (ASTM D695-96), and impact testing (ASTM D256), while morphological structure analysis was carried out using Scanning Electron Microscope (SEM) testing. The results showed that the volume fraction composition of 25:5:70 produced the highest tensile strength with an average value of 95.69 N/mm² and the highest impact strength of 29.91 J/mm. Meanwhile, the composition of 15:15:70 obtained the highest compressive strength of 57.13 MPa. SEM analysis of the composite fracture showed the occurrence of full out fiber, debonding, and void phenomena in the matrix, which affected the decrease in the material strength value. This indicates that variations in the composition of bamboo fiber and glass powder can optimize the mechanical properties of composites, while supporting the utilization of natural materials and waste as environmentally friendly innovation materials for automotive applications, especially Yamaha Vixion motorcycle visor products.

Rapid advancements in science and technology have increased the demand for renewable and high-performance composite materials. Sugarcane bagasse, an agricultural waste, has potential as a natural fiber reinforcement in composite materials. This study investigates the use of sugarcane bagasse fibers with epoxy and polyester resin matrices for manufacturing the handle reclining component of the Toyota Kijang Kapsul. Molds were successfully fabricated using Silicon Rubber RTV-52 with a catalyst ratio of 1:25, producing precise molds suitable for composite fabrication. Compression testing revealed that epoxy-based composites achieved an average maximum compressive load of 10,673.49 N, approximately 28% higher than polyester-based composites, which averaged 8,332.83 N. Epoxy composites also showed more consistent performance across specimens. Structural analysis using ANSYS indicated that composite handles exhibited lower deformation, higher equivalent stress, and greater safety factors d to plastic counterparts. The handle reclining parts produced from epoxy resin and sugarcane bagasse fibers with a 25:75 fiber-to-resin ratio successfully replicated the original part's appearance and demonstrated superior mechanical performance. This study contributes to the development of cost-effective, environmentally friendly composite materials with practical applications in the automotive industry.

Bioethanol as an alternative energy source for fossil energy conversion. A potential source of bioethanol is Ciu Gumayun, a liquor with 25% alcohol content, which can be purified through adsorptive distillation using natural zeolite and silica gel as water adsorbents. The study aimed to determine the effects of adsorbent variations on the alcohol, water, and calorific value of bioethanol using a multistage adsorptive distillation process at 78°C with 2 liters of Ciu and 70 grams of adsorbent in each distillate. The results of the natural zeolite adsorption distillate: alcohol content of 67%, 79%, 88%, and 92%, with a final volume of 162 ml. In the silica gel adsorption distillate, alcohol content: 68%, 79%, 86% and 92%, with a final volume of 170 ml. The water content of both natural zeolite and silica gel distillates was 8%, with water volumes of 12.96 ml for natural zeolite distillate and 13.6 ml for silica gel distillate. The calorific value was 24,147 J/g for natural zeolite distillate and 24,704 J/g for silica gel distillate. From the alcohol content, water content, and calorific value, silica gel proved to be more effective in the adsorptive distillation process.
