Hydrocyclone is a tool used for the separation of solid materials in the carrier medium by utilizing the generated vortex effect of centrifugal force. Hydrocyclone consists of a vertical cylindrical portion with a funnel-shaped bottom part, inlet doors on the upper side, the door at the bottom of the underflow and overflow at the top of the door. In this study will be known how widespread the effect of head and underflow of the water in the sediment separation efficiency hydrocyclone apparatus. Variations on hydrocyclone efficiency of 94.1% due to the broad head and underflow and the remaining 5.9% is influenced by other things that can not be explained by existing variables. Between the head and sediment hydrocyclone separation efficiency are unidirectional relationship but weak. Wide underflow with sediment hydrocyclone separation efficiency occurs negative correlation is very strong and has a closeness, while the head and broad underflow there is no relationship. The best analysis model in predicting the dependent variable (sediment hydrocyclone separation efficiency) with the influence of the independent variables (head and broad underflow) is a multiple linear regression model with a predictive equation Y = 0612 + 0915 head - spacious 0646 underflow. Prediction efficiency hydrocyclone separation highest sediment that occurs at 98 746% with the results of laboratory studies of 99 781%, which is at the head of 50% and 13% of the underflow broad inlet door. Key words: hydrocyclone, head, broad underflow, the separation efficiency of the sediment, and water

As already known, one alternative to solve run-off problem is by recharging the water into soil by mean of adiffusion system. This way can be expected to be able to conserve ground water. This research was aimed to model a diffusion system conserving rainfall runoff and ablution waste from the mosque of Al-Wasi'i of Lampung University. This research was conducted from July to September 2011. Experiment data used in the modeling consisted of a week daily ablution waste discharged from the mosque, percolation rate, surface evaporation. The ablution waste data was collected both on and off semesters. Percolation rates of three location sites aroung the mosque were measured by using double ring infiltrometer. Surface evaporations were measured by contructing a 30x30x45 cm glass container simulating a runoff collector. The actual evaporation was then used to calibrate the constant (K) by comparing with the Penmann reference evapotranspiration (ETo). The contant was then validated by another group of actual evaporation data. In addition to the experimental data, a 10 year daily climotological data was also used and collected from the nearest weather station. The model consisted of input conponents: praying ablution wsate, runoff from the mosqueâ€™s roof, direct rainfall, and output components: overflow, evaporation, and percolation. The model simulated daily up and down water surface of the diffusion system. The result showed that there were three different percolation rates from three diferent locations, but the stable rate of 1666.12 mm/day was more likely representative and used in this model. Based on the simulation, diffusion system of 3 m depth and 8 m2 area could conserve the water by 70%.

Stunting is one of the nutritional problems that has not been resolved and the incidence rate is still quite high in Magetan Regency, especially in the Panekan Community Health Center working area, namely 49.1%. Toddlers with stunting have an impact on growth and development that is not optimal physically and psychomotorically. This research aimed to analyze the factors that cause stunting. This research was an analytical survey study with a cross-sectional design. The population was 251 toddlers in 17 villages in Panekan District. The sample size was 163 toddlers taken using proportional random sampling and simple random sampling techniques. Independent variables were gender, exclusive breastfeeding, history of LBW and parity; while the dependent variable was the incidence of stunting. Data collection was carried out using children's cohort book documentation and recapitulation data from the Panekan Community Health Center. The collected data was analyzed using a logistic regression test. The research results showed that the majority of toddlers with stunting were male, born LBW, not given exclusive breast milk, and born to mothers with grandemultiparous parity. The results of statistical analysis showed that factors that were significantly related to the incidence of stunting were gender (p = 0.033, OR = 1.84), history of low birth weight (p = 0.000, OR = 28.3), exclusive breastfeeding (p = 0.000, OR = 58.8) and parity (p = 0.002, OR = 6.49). It was concluded that the factors that contributed to the occurrence of stunting at the Panekan Community Health Center included gender, low birth weight, exclusive breastfeeding, and parity. The dominant factor causing stunting is breastfeeding.Keywords: exclusive breastfeeding; low birth weight; gender; parity; stuntingABSTRAK Stunting merupakan salah satu masalah gizi yang belum terselesaikan dan masih cukup tinggi angka kejadiannya di Kabupaten Magetan, khususnya di wilayah kerja Puskesmas Panekan yaitu sebesar 49,1%.
