Abstract
In this paper the author will try to review whether the development process of a video game relates to its quality. The worldwide video game industry had its ups and downs from their beginning in the 1950s until the present, with many video games released to success, but there are many which fails. To find the relationship between the development process of a video game and its quality, the author tries to study the development of 20 video games from a multitude of genres by AAA developers and publishers in the last 10 years and comparing their respective critical reception and sales. This paper tries to answer the question on whether a video game will be successful or failed in the commercial market based on its development process, marketing and life cycle. From the recent trends, the result is most likely inconclusive or varied depending on the video game in question. The author expects that this paper will give an insight about the development of video games to the readers and act as a basis to decide whether a video game can be considered a success or a failure in the market.

Abstract
Measurement of growth and development in children is the most important thing related to early and appropriate management that can be done if deviations are found. Growth measurements are measurements of the childs weight, height and head circumference. Some previous studies have shown that there are many delays in child development. There are several ways that can be used to screen development, one of them is by using a developmental pre-screening questionnaire that requires special officers trained in its implementation. The results of measurements of growth are often associated with development in children. Based on this, further research is needed regarding the relationship between screening for development and growth in children. The purpose of this study was to analyze the relationship between the results of screening on development using the KPSP method and the results of measuring growth parameters in children aged 0-6 years in Denpasar. The study was conducted using cross sectional analytic. Based on the Pearson correlation test (α = 0.05), it shows that there is a significant negative correlation (r = -0.218; p <0.05) between weight and development. This shows that the higher body weight will further reduce the level of child development.

Abstract
In Indonesia, especially in urban area such as Jakarta, it is very common that greywater generated from households run off into drainage system. The greywater that mixed together with rain water will flow onto river. Increasing population means increasing in households as well as greywater generated, that become serious problem when greywater becomes dominant in drainage system. To minimize the pollution from greywater in river stream, it was used the constructed wetland with subsurface system in riverbanks of Ciliwung river. The research was conducted using the vetiver (Vetiveria zizanioides) planted in the subsurface-constructed wetland to decrease the parameter of ammonia and phosphate from greywater. The aim of the research is to determine the removal efficiency of the parameters from greywater using the wetland located in Srengseng Sawah subdistrict, South Jakarta City. With the residence time of 2 days, the parameter of ammonia could removed 70% while for phosphate parameter is 65%. To reach the quality standards, it is suggested to add the pre-treatment of aeration for the wetland.

Abstract
This research purpose to remove copper heavy metal (Cu2+) with a biotechnological approach using mixed microalgae Chlorella sorokiniana, Monoraphidium sp. and Scenedesmus obliquus which is bound in Na-Alginate polymer. The effect of contact time and temperature on the biosorption rate was examined to achieve the greatest efficiency in the Cu2+ metal removal process. Bonded biosorbents are made by drying in an oven, grinding, and trapping into polymer alginate to form immobilized microalgae or called beads. The decrease in Cu concentration was analyzed using Atomic Absorption Spectroscopy (AAS). The absorption properties of biosorbents were characterized using Fourrier Transform Infrared (FTIR) and Scaning Electron Microscopy (SEM). Optimization of absorption parameters was carried out in a batch system using a concentration of 20 mg/L Cu wastewater, biosorbent concentration 0.5 g/g, pH 4 with contact time setting (60, 120, 180) minutes and temperature regulation (25, 30, 35)oC. The results showed that maximum biosorption occurred at pH 4, temperature 30oC and contact time 120 minutes with removal efficiency 82%.

Abstract
Ferrous is one of the groundwater contaminants that negatively impacts health and the environment. The allowed ferrous content is < 1 ppm in water for daily use. Removal of Fe in groundwater by adsorption using low-cost bio-sorbent from rice husk has been conducted. The process was carried out in continuous mode using two types of rice husk-sourced adsorbents, one was only carbonated at 400 C and another was followed by a physical activation at 650 C. To study the effects of physical activation on the surface characteristics, both types of bio-sorbents were characterized by Scanning Electron Microscope and Fourier-transform infrared spectroscopy. The concentration of artificial sample before and after adsorption was evaluated using the Atomic Absorption Spectroscopy. From the results, the adsorption using physically activated sorbent had greater removal efficiency of 74.02% compared to that of without activation treatment, which was only 65.70%. In addition, the concentration of ferrous was successfully reduced to 1,029 and 0.779 ppm from the initial concentration of 3 ppm for the process using the adsorbent without and with activation, respectively. It can be concluded that the physically activated rice husk has the potential to be used for adsorption of Ferrous in continuous reactor.

Abstract
Stunting is a growth disorder based on measurement of PB / U or TB / U characterized by a short body state. Toddlers were categorized short if the z-score of the scores is less than -2SD. In Indonesia 29% of children are short category. There are several risk factors that influence stunting including short-term pregnancy, mother-s height, LBW, number of children, age of MP-ASI, exclusive breastfeeding and frequency of infection history with stunting in toddlers. The purpose of this study was to determine the risk factor of stunting in toddlers at Puskesmas Klungkung I. This research is a case-control research with retrospective approach. The sample size used in this study were 35 case samples and 70 control samples, through purposive sampling technique. The data collected in the form of primary data and secondary data. Data were analyzed by bivariate analysis with chi square test and multivariate analysis with multiple logistic regression. Chi square test showed that the risk factors for stunting were LBW, exclusive breastfeeding, age of MP-ASI, frequency of infection history and mothers height. Gestational distance and the number of children were not risk factor for stunting in this study. Multiple logistic regression test showed LBW (OR = 21,98; 95% CI: 2.04-237,69) and mother height (OR = 7,37; 95% CI: 1,94-28,02) became dominant risk factor of stunting incidents in toddlers at Puskesmas Klungkung I. These results indicate that mother-s height and LBW are the risk factors for stunting. Therefore, they need more attention to reduce the incidence of stunting.

Abstract
Green Chemistry principal was introduced in an academic environment in the 1980s as guidelines for sustainable development focused on chemistry. Efforts to realize these expectations can be applied through education by developing learning process based on environmental. This study aims to apply the concept of Green Chemistry in education, especially chemistry learning by producing natural acid-base indicators from the extract of roses (Rosa sp) and Rosella (Hibiscus sabdariffa L). These indicators are produced by the method of extraction using 96% ethanol solvent in an acidic atmosphere at pH 3-4. The results of maceration then extracted in three different solvents (ethanol, n-hexane, and chloroform). The extract was tested in solution with pH 1-12 and used as an indicator to identify the solutions and titration in acid-base topic.

Abstract
In this field, which has used this waterflooding technique as it goes through, there is a solid production which causes sand problems. Sand problems that occur result in increased production loss and cost lost. The purpose of this research is to find the right solution in overcoming sand problem, by studying the characteristics of the rock. Laboratory experiments were carried out using a mechanical method approach which was then used to determine the appropriate gravelpack design. The steps taken include testing the strength of the core of the three zones, The decrease of strength can conclude that the core of the three zones has begun to weaken. The results of the analysis of the grain size of the D50 then used to determine the appropriate gravelpack design in each zone. Zone A, using gravelpack 60/80, zone B using gravelpack 16/20, and zone C using gravelpack 30/50. From the gravelpack design obtained then a sand retention test is performed to determine the gravelpacks performance. With the results of the sand retention test showing good gravelpack performance for each zone, where the permeability value is good and the solid produced is not too much.

Abstract
Scaffolding is a technique that can be used to make learning more meaningful. It is designed to help students realize their goals and provide support for students in need in the learning process. It is important to understand that students have their own development tempo, or better known as Zone Proximal Development (ZPD). Therefore, the teacher can conduct the learning process in accordance with the ZPD of each student. This individual difference will affect the students learning process and outcome. This study, which was conducted using descriptive qualitative design, was aimed at describing the application of scaffolding in each stage of Situation-Based Learning (SBL) in the topic of Force. Respondents in this study include fifth-grade primary school students aged 10 to 12 years old. The study found that optimal scaffolding could maximize students learning processes in understanding the concept of Force. This maximum learning process could later affect the quality of the students learning outcomes.

Abstract
This study aims at presenting school management model based on character building in teaching learning process. This survey research was conducted at 450 elementary schools in Jakarta in Indonesia. Structural Equation Modeling (SEM) was used in analyzing data. Study result found that model hypothesized was a good fit for the data shown by RMR reaching 0.039, GFI reaching 0.919, and AGFI reaching 0.848. Other findings confirmed that teaching learning process preparation, teaching learning process, and teaching learning process closing are positively correlated with character building in teaching learning process. The three dimensions consisting of praying, connecting teaching material with good attitude development, and supervising the student uniform cleanliness have positive correlation with preparation of teaching learning process. Teaching learning process can be predicted by teaching cooperation in teamwork, encouraging student to ask questions, and paying attention to student attitude. The three dimensions determining closing of teaching learning process are praying, greeting, and reflecting by integrating with character values. It can be concluded that the model of school management focusing on character building in teaching learning process proposed can be used by elementary schools in Jakarta to improve student character building.

Abstract
Biosurfactants are surface-active molecule produced by microorganisms and have several advantages over the chemical surfactants. The objective of this research was to obtain biosurfactant-producing bacteria from hydrocarbon contaminated soils in Jakarta Bay and to observe their biosurfactant activity through emulsification capacity and surface tension reduction capability. Overall, 19 isolates were screened for biosurfactant production by hemolysis assay, drop collapse assay and oil spreading assay. The result showed that 12 strains gave positive results on the screening tests and were determined as biosurfactant-producing bacteria. Three strains (TKY 3, TKY 14 and TKY 19) had the best biosurfactant activity. Isolate TKY 3 has the best emulsification index (E24) with a value 57±0,57%, while the lowest surface tension value was achieved by two strains ( TKY 19 and TKY 14 ) with the same value of 37,84±1,45 mN/m.

Abstract
Lignin is an essential bio-polymer which is required in the formation of plant cell wall. The degradation of lignin in the nature is a major challenge due to the complexity of its structure. It has been long known that white rot fungi produce ligninolytic enzyme that can degrade lignin efficiently. To identify white rot fungi, screening test was carried out by testing different strains of Basidiomycota using czapek dox agar supplemented with Guaiacol (0,02%). The results showed that two out of thirteen strains of Basidiomycota have ligninolytic activity. In this study, we successfully obtained two strains that have ligninolytic activity. This study sheds light on further observation of these strains which potentially can be used for lignocellulose waste treatment especially oil palm empty fruit bunch (OPEFB).
