Increasing the number of laundry industry influences on the increasing of detergent utilizzation. Thedominant substance contained in the detergent is Natrium Tripolyphosphat, a builder and surfactant.Therefore the waste contains Phosphate. Most of the laundry industry throw their waste without treatmentfirst. The waste would cause Eutrofication where the water body became rich of dissolved nutrient,descending of the dissolved oxygen and capability of water body assist power to water biota. Lumintu isone of the laundry industries which located in Tembalang district. According to the result of preexperiment,industrial waste water containes 10,21 mg/l phosphate. This value exceeds standard quality ofPerda Prov. Jateng no. 10 year 2004 about maximum value for total of phosphate is 2 mg/l. One ofwastewater treatment method is adsorption using the active carbon from plastic rubbish kind ofPolyethylene. This reseach purposes to know the capability of active carbon from plastic rubbish inreducing phosphate content with batch and column operation. The batch operation use 1,2 and 3 gramvariation weight active carbon from plastic rubbish for 30 - 60 mesh and 100 - 200 mesh variation mediasize. The batch operation has 45,45 % from the highest phosphate efficiency lowering on the 3 gram.Otherwise, column operation need 1 inch column diameter with 50 ml/minute and 100 ml/minute debitvariation. Continue trial had 54,75 % from the highest phosphate efficiency lowering on the 50 ml/minute.Constant value speed (k1) is 0,0108 ml/mg.s with capacity of adsorption (qo) 0,677 mg/g.

Diabetes Melitus (DM) merupakan penyakit kronik, oleh karena itu peran self-managementsangat penting dalam perawatan maupun pencegahan komplikasi akibat DM. Penelitian ini bertujuan untuk mengetahui gambaran perilaku self- management.pasien DM dari aspek diet, medikasi, olahraga, pemantauan kadar gula darah dan perawatan kaki. Sebanyak 94 responsden diambil secara acak. Perilaku self-managementdiukur menggunakan kuesioner yang dikembangkan oleh penulis, dengan skor Alpha Chronbach 0,930 dan korelasi inter-item 0,385–0,797 dimana nilai tersebut valid dan reliabel untuk uji instrumen. Hasil penelitian menunjukkan lebih dari setengah responsden (64,9%) melakukan lima aspek self-managementdengan baik. Hampir semua responsden (94,7%) melakukan medikasi dengan baik, lebih dari setengah responsden melakukan diet (69,1%), olahraga (61,7%) dan perawatan kaki (77,7%) dengan baik. Namun hanya 25,5% responsden yang melakukan pemantauan gula darah dengan baik. Hasil penelitian ini dapat menjadi acuan bagi perawat untuk memberikan penyuluhan mengenai pentingnya pemantauan pada gula darah.Kata kunci: Diabetes Melitus, perilaku, self-management AbstractDiabetes Mellitus (DM) is one of the serious health problems in Indonesia. Since DM is a chronic disease, patients’ role (self-management) is very important either for treatment or DM-related complications prevention. This study was purposed to determine the level of patients’ diabetes self-management behavior, including diet, medication, exercise, blood glucose monitoring and foot care. Ninety-four responsdents were recruited randomly by gave the informed consent to diabetes patients. The questionnaire was developed by the researcher, with Chronbach Alpha 0,930 and inter-item correlation 0,385 to 0,797, which mean the instrument was valid and reliable. The results showed that in five aspects, more than half of responsdents (64,9%) reported that they performed good self-management. Almost all responsdents (94,7%) reported good medication, more than half of responsdents did well in diet, exercise (61.7%) and foot care (77.7%). However, only 25.5% responsdents who performed monitoring blood glucose levels properly. It called be good level when it fill the score criteria of the answer.Therefore, it was recommended for nurses and the hospital to develop any program to improve patients’ diabetes self-management behaviors, especially in the monitoring blood glucose.Key words: Behavior, diabetes mellitus, self-management

Electrocoagulation is selected method to decrease concentration of heavy metal Cr and Zn, because it is easy in operation without using chemical addition that harmful for human. The purpose of this research studied the influence of efficiency toward the loading of concentration and the performance of electrode during electrocoagulation process used on continuous system. This experiment used three types of artificial wastewater, they were waste 1 contained 30.11 mg/L of Cr, 50.61 mg/L of Zn, 50.14 mg/L of Cu, waste 2 contained 41.08 mg/L Cr, 105.30 mg/L Zn, 103.25 mg/L Cu, and waste 3 contained 50.07 mg/L of Cr, 202.58 mg/L of Zn, 208.61 mg/L of Cu. This experiment used aluminum electrode with dimension of 10 cm x 15 cm, voltage of 12 volt, current strength of 5 ampere, and the operating time was 360 minutes by taking sample every 30 minutes. There was the washing of electrode every 120 minutes to increase the performance of electrode. Based on the research had been obtained the optimum time at each sample was 120 minutes which research up to 97% of efficiency and the optimum time of using electrode was 240 minutes. The best reduction of Zn reached 97.68% with the initial concentration of 50.61mg/L.

Electroplating industries produce wastewater containing heavy metals such as copper and chromium that can pollute the environment because they are toxic and harmful to human health despite a small quantity. However, they require a wastewater treatment that could decrease heavy metal waste. Electrocoagulation is the selected method because it has high ability to treat heavy metals wastewater and the equipment is simply enough. The experiments were conducted with artificial wastewater with varying concentrations of Cr 30, 40 and 50 mg/ l and Cu respectively 50, 100 and 200 mg/l. This study used an electrode type Aluminum (Al) that had distance 1.5 cm each electrode, 5 ampere current strength, sampling time every 30 minutes, time operation 360 minutes with an electrode washing every 120 minutes. From the experimental result had been obtained the best efficiency to reduce Cr and Cu occurred in minute 120 which up to 97 %. Aluminum electrode having saturation began at minute 270.

Banger River is the river with a length of 6.5 km and coverage area of 524,46 ha.The determination status of water quality in Banger River necessary to know how the water pollution in Banger River and recommendations related to the control of pollution river.This research aims to analyze the causes factors changes concentrations of TSS, BOD, COD, DO, pH, Amonia, and Nitrate; calculate the pollution indexon all sampling point inBanger River, and analyze the influence of concentrations of TSS, BOD, COD, DO, pH, Amonia, and Nitrateto water quality status of Banger River.Pollution index were analyzed based on KepMen LH No. 115 in 2003 about the determination the Status of Water Quality Guidelines by taking 5-point sampling and dividing the region segmentation into 4 segments. From this research, a pollution index values are calculated at the BGR point 1 is 8,17; BGRpoint 2 of the resettlement 9,17; BGRpoint 3 of the resettlement 5,17; BGRpoint 4 of the resettlement 7,03 ; and at that BGRpoint5 is 7,48. Based on KepMen LH No. 115 in 2003 about the determination of the Status of Water Quality Guidelines, the value of the IP is at 5,0 < PIj ≤ 10 categorized into polluted medium. So the water quality status at all Banger River the segmentation categorized polluted medium.
