Skripsi ini membahas analisis performa dari pengembangan prototipe kendaraan bawah air berbasis Low Cost Remotely Operated Vehicle (LCROV) yang diberi nama Makara-06. Pembuatan prototipe dilatar belakangi kebutuhan kendaraan tanpa awak yang besar untuk kegiatan maritim Indonesia, namun masih sedikit pengembangan yang dilakukan di dalam negeri. Makara-06 dirancang dengan tipe lambung closed-frame, memiliki 3 derajat kebebasan dan memiliki titik berat yang rendah untuk dapat melakukan manuver dengan stabil sehingga pengambilan gambar dapat dilakukan dengan akurat. Hasil analisis memperlihatkan Makara-06 memiliki manuver yang baik dengan kecepatan rata-rata maksimum 2 knot secara horizontal dan 0.2 knot secara vertikal. Pengembangan ke depan diharapkan desain yang dihasilkan lebih hidrodinamis pada beberapa bagian dan sistem elektrik yang lebih ringkas serta mampu beroperasi secara autonomous sehingga performa dan fungsi Makara-06 lebih baik dari prototipe pertama.

This essay shows the analysis of the performance of underwater prototype based on LCROV (Low Cost Remotely Operated Vehicle) named Makara-06. This prototype is designed because the minimum number of ROV development compared to the needs of unmanned maritime vehicle for Indonesian maritime. Makara-06 is designed with closed-frame type hull, have 3 Degree of Freedom and a low Center of Gravity to be able to maneuver in a stable condition to get accurate live streaming feedback. Analysis shows Makara-06 have good maneuverability with average maximum speed is 2 knot horizontally and 0.2 knot vertically. The next development is hoped to have more hydrodynamic feature in some part of the hull, have a more compact and rigid electrical system and can function autonomously so that the next Makara-06 can have a better performance and functions than the first prototype.

Abstrak :
The study was a double-blind, controlled, randomized by episode in two sub-district rural areas ± 200 km from Jakarta, in which 1,185 children under three years of age were assigned to receive 4-5 mg element zinc/kg bw/day as a daily dose in two divided doses for the consecutive days during diarrhea Children were visited at their home every week for 12 months and they also underwent oral rehydration therapy. After 12 months observation there were 2, 410 episodes, 131 were excluded due to lack of information.
Among children of zinc supplementation group there was 11% reduction (95% confidence interval, 3 to 18%) in the risk of continued diarrhea. In children with watery diarrhea there was a decreased of 12% (95% confidence interval, 3 to 21%) in the number of days in the zinc supplementation group. The reduction in the likelihood of diarrheal duration was 18% (95% confidence interval, 4 to 43%) in children who were given antibiotics before enrollment. Among children who had 3 episodes during 12 months observations there was a greater reduction in diarrheal duration (RR. in the zinc supplementation group = 0.79; 95% confidence interval, 0.64 - 0.97). Zinc supplementation in children with stunted growth was associated with 8% reduction of the risk of continued diarrhea, but statistically not significant (95% confidence interval, -9 to 21%). Children in zinc group had a lower proportion of persistent diarrhea (z 14 days) than control group zinc supplementation resulted in a 44% (95% confidence interval, 2 - 70%) reduction in the incidence of persistent diarrhea.
These findings suggest that zinc supplementation in children with acute diarrhea significantly reduced the duration of diarrhea and the risk of persistent diarrhea. Zinc supplementation may have a significant effect on childhood diarrhea-related mortality.
