PT. Astra International Tbk recorded the demand for the use of lubricants as one of the spare parts components sought by Honda motorcycle consumers to continue to increase where at the end of 2015 lubricant parts sales were recorded at 18,596,521 lubricants and each month on average they needed around 1,149,125 lubricant (Gani, 2016). In the case of waste producers, B3 waste management can be transferred to other parties accompanied by documents showing evidence of delivery of B3 waste, in accordance with the contents of Article 32 Paragraph (2) Government Regulation Number 101 of 2014. The meaning transferred here can be interpreted as being sold to another party, because the waste of used lubricating oil still has economic value. This study aims to determine the process of managing lubricating oil waste at Astra Motor Balikpapan. This study was designed as a descriptive observational evaluation study conducted cross sectionally by observing, analyzing, observing and processing data and information that has been systematically collected. The results showed that the management of used lubricant waste at Astra Motor Balikpapan was quite good, but there were some things that needed to be improved including control from Balikpapan BLHD supervision, workshops and continuous counseling and the absence of strict administrative sanctions.

Joint waste management between regions that bordered each other can be one alternative solution of the problem of trash in Indonesia. Some areas have conducted cooperation in waste management, such as Sarbagita and Kartamantul. Dynamic game can be an alternative method in joint waste management between the regions. The purpose of this article is to design joint waste management between regions using the dynamic game theory framework approach. A dynamic game is a mathematical model that represents the conflict situation between the interested parties who want to make the best decision (in this case it is the city/district government) of a series of strategies that are possible by considering the existence of the various uncertainties at such situation. The discussion is done by assuming there are three areas of the bordering regoins and making some waste disposal regulations. Furthermore, the mathematical operations and simplification of the form of equation are executed to adapt to the design objectives. The results of the design in this approach are the invention of two mathematical equations describing the characteristics of dynamics waste stock in the adjoining regoins, and the cost to be incurred by each regions in managing its waste stock.

Mothers who exclusively breastfed their babies from 2011-2015 tended to increase. However, in breastfeeding there are still many maternal understandings that are lacking about foremilk and hindmilk. Foremilk and hindmilk are related to the duration of the baby breastfeeding, if the baby has not been obtained in a balanced manner can cause problems in the pattern of defecation of infants especially those aged 1-6 months. The purpose of study was to determine the effect of foremilk and hindmilk balance with defecation patterns of infants who received exclusive. The study design was cross sectional, with total sample 30 mothers who had infants aged 1-6 months and exclusively. The results showed the majority (96.7%) frequency of defecation of infants 1-8 times, consistency of soft stool (96.7%) and yellow stool (93.3%). Out of 30 respondents 53.33% of mothers had a balance of foremilk and hindmilk while breastfeeding and 86.66% of infants had normal defecation patterns. Chi-square test results did not influence the balance of foremilk and hindmilk with the pattern of defecation with 30 respondents surveyed. This shows that the balance of foremilk and hindmilk has not affected the pattern of infant defecation including frequency, consistency and color of feces.

Copper pollution in the East Coast of Surabaya is one of the serious cases of heavy metal pollution in Indonesia. Pollution at this location has been proven to result in fish deaths and brain damage of local residents because they consume too much copper-contaminated fish. Copper bioremediation using indigen bacteria isolated from polluted environments is a promising solution to overcome copper pollution problems. Bacteria that commonly live in polluted environments can be isolated and used as copper bioremediation agents. This study aims to do: 1) isolation and characterization of copper resistant bacteria from the East Coast of Surabaya, 2) resistance testing of bacterial isolates, and 3) copper accumulation and biosorbtion tests of bacterial isolates. The bacterial isolates were characterized by the morphology of the colonies and their cells based on Gram staining. Resistance testing is done by determining Minimum Inhibitory Concentration/MIC. The accumulation test is carried out by separating the cell and growth medium, then each of them is distructed using HNO3. The results of isolation and characterization obtained six isolates of copper-resistant bacteria, namely PmbC1, PmbC2, PmbC3, PmbC4, PmbC5, and PmbC6 with MIC = 3 mM - 5mM CuSO4. PmbC4 isolate is the most resistant bacteria with the MIC of 5 mM and is capable of accumulating copper of 6.25 mg per gram of cell dry weight and biosorbtion of 92.17%.
