PT. Ima Montaz Sejahtera merupakan suatu Perusahaan Industri Air Minum Dalam Kemasan (AMDK) dengan merk “Mount Agua” dan perusahaan ini menghasilkan produk berupa produk gallon 19 liter, produk botol 1500 ml, produk botol 600 ml, dan produk gelas 240 ml. Pabrik PT. Ima Montaz Sejahtera memiliki dua buah gudang yaitu gudang material dan gudang produk jadi, didalam pengoperasian proses produksi banyak waktu yang terbuang untuk mengangkut material dari gudang ke mesin produksi dan ini disebabkan letak gudang material jauh dari mesin produksi dan juga dalam mengangkut material dari gudang ke mesin produksi harus melalui gudang produk jadi sehingga mengganggu aktifitas proses produksi. Metode yang digunakan pada penelitian ini menggunakan metode center of gravity yaitu menentukan titik pusat letak gudang baru berdasarkan tata letak mesin-mesin produksi.Dengan meningkatnya waktu produksi maka dengan sendirinya kapasitas produksi juga meningkat untuk produk gallon 19 liter sebesar 36 gallon per minggu (0,490 %), produk botol 1500 ml sebesar 211 karton per minggu (2,475 %), produk botol 600 ml sebesar 71 karton per minggu (1,172 %), dan produk gelas 240 ml sebesar 186 karton per minggu(0,731 %).Kata Kunci: Optimalisasi, Tata Letak Gudang, Centre of Gravity, Lay Out.

This paper describes the experimental estimation of the mini-helicopter inertia and center of gravity (CG) location. A three degree of freedom inertia test rig and an Inertia Measurement Unit (IMU) were used to measure the oscillation frequencies about three axes under different configurations. These frequency data are then manipulated to estimate the inertia tensor and CG location of the mini-helicopter model.

Backpack Weight

Increasing weight of backpacks of school going students and its adverse effect on children’s body is shown through survey of Indore city. Outcome of survey shows that the average of ratio of backpack weight to body weight of school children was 20.62% which is higher than acceptable limit. It gives a method to reduce the impact of schoolbag on spinal cord of children body. In this paper, the effect of center of gravity of schoolbag on human body is observed which is shifted in a position which lowers the effect of schoolbag stress by applying CGSHIFTER method.

Abstract:In this study we have attempted to classify the acceleration signal, while walking both at horizontal level, and upstairs and downstairs, using wavelet analysis. The acceleration signal close to the body’s center of gravity was measured while the subjects walked in a corridor and up and down a stairway. The data for four steps were analyzed and the Daubecies 3 wavelet transform was applied to the sequential data. The variables to be discriminated were the waveforms related to levels -4 and -5. The sum of the square values at each step was compared at levels -4 and -5. Downstairs walking could be discriminated from other types of walking, showing the largest value for level -5. Walking at horizontal level was compared with upstairs walking for level -4. It was possible to discriminate the continuous dynamic responses to walking by the wavelet transform.

This paper describes hydrodynamic model tests of Wing in Surface Effect (WiSE) Craft. These craft  was fitted with  stephull  form in different location on longitudinal flat bottom (stepedhull planning craft) to determine the influences of sticking and porpoising motion performances. These motions are usually occured when the craft start to take-off from water surfaces. The test models with scale of 1 : 7 were comprised of 4 (four) stephull models and 1 (one) non-stephull model  as a comparative study. The hydrodynamic  tests were performed with craft speed of 16 – 32 knots (prototype values) in Towing Tank at UPT. Balai Pengkajian dan Penelitian Hidrodinamika (BPPH), BPPT, Surabaya. The resistance (drag) was measured by dynamo meter and the trim of model (draft changing at fore and aft  of model due to model speed) was measured by trim meter. By knowing the value of model trim, the wetted surface area can be determined. Then, the lift forces were calculated based on these measured values. The model test results were presented on tables and curves.  Test results show that models  with step located far away from center of gravity of the WiSE craft tend to porpoising and sticking condition, except if the step location on the below of these center of gravity. While model without step tends to sticking conditions.
