Open Dumping

The Benowo Landfill (TPA) in Surabaya applies the Open Dumping method so that it has the potential to produce leachate which can pollute the surrounding environment. The leachate storage system in TPA Benowo also plays a role in the possibility of leachate leaking into groundwater and polluting the quality of freshwater aquaculture pond water around Benowo TPA. The method used is the purposive sampling method, which is by taking several samples scattered around the center of the Benowo landfill waste dump, then testing the COD concentration, which is then the results of the COD measurement, plotted on a map to analyze the distribution pattern. The results showed that there was an indication that pond water around the Benowo landfill had been contaminated with leachate which was shown by the COD concentration in 14 test samples, only 3 according to the quality standard of PP RI No.82 of 2001.

The Community Partnership Program (PKM) activity has been carried out in Nagari Sunua, Padang Pariaman District, West Sumatra. As for Sunua's diversity, many young people drop out of school and do not have permanent jobs. This activity aims to provide training in the manufacture of aquaponic systems that combine freshwater fish cultivation with vegetable cultivation simultaneously. Partners will be given training on how to use freshwater aquaculture pond water to grow vegetables. Pool water will be flowed in the pipes where the vegetable seeds are grown. Pond water becomes fertilizer and nutrition for vegetables. Water that has passed through vegetables in the next pipe will be flowed back into the pond. This aquaponic cultivation pattern is very beneficial because it can produce vegetables and fish simultaneously in one activity. This can be a new type of business for partner groups that have not. In general, these activities can be carried out well and increase the knowledge and skills of the members of the partners involved.

Penelitian ini merupakan penelitian deskriptif kuantitatif dengan mengkaji kondisi kualitas air perairan danau Paniai, Papua. Pengambilan dan pengukuran sampel air pada setiap lokasi sampling dilakukan dengan metode composite sampling (gabungan tempat). Contoh air danau diambil pada permukaan dan pertengahan. Pengukuran dan pengumpulan data dilakukan sebanyak 2 kali dengan interval waktu antar pengukuran selama 1 bulan. Hasil penelitian didapatkan parameter fisika masih memenuhi syarat baku mutu, parameter kimia, dari delapan parameter yang diukur terdapat 3 parameter yang tidak memenuhi baku mutu yaitu, H2S, Nitrat dan Posfat. Hal ini menunjjukan bahwa tingginya buangan limbah dari sektor pertanian dan rumah tangga yang masuk ke dalam danau dan berpontesi terjadinya eutrofikasi dan peledakan pertumbuhan tanaman air. This study aims to analyze the feasibility of the waters based on the physical, chemical and biological parameters of the waters of Paniai lake for fish farming activities. This research is a quantitative descriptive study by examining the condition of the water quality of the waters of Lake Paniai, Papua. Water samples were taken and measured at each sampling location using the composite sampling method (combined places). Lake water samples were taken at the surface and in the middle. Measurement and data collection were carried out 2 times with an interval of 1 month between measurements. The results showed that the physical parameters still show the quality standard requirements, chemical parameters, from the eight parameters measured there were 3 parameters that did not show the quality standards, namely, H2S, Nitrate and Phosphate. This shows that the high discharge of waste from the agricultural and household sectors that enters the lake has the potential for eutrophication and explosive growth of aquatic plants.

Software systems are any software product or applications that support business domains such as Manufacturing,Aviation, Health care, insurance and so on.Software quality is a means of measuring how software is designed and how well the software conforms to that design. Some of the variables that we are looking for software quality are Correctness, Product quality, Scalability, Completeness and Absence of bugs, However the quality standard that was used from one organization is different from other for this reason it is better to apply the software metrics to measure the quality of software. Attributes that we gathered from source code through software metrics can be an input for software defect predictor. Software defect are an error that are introduced by software developer and stakeholders. Finally, in this study we discovered the application of machine learning on software defect that we gathered from the previous research works.

AbstractBackgroundEarly career doctors (ECDs) are faced with many challenges due to their transition from undergraduate medical/dental studentship to being postgraduate doctors and being in an early phase of their career. The specific factors that affect ECDs in their careers and endeavors at the workplace range from poor remuneration, particularly in developing countries, to psychosocial problems (such as burnout [BO] syndrome). There is a dearth of information on BO among ECDs in Nigeria. This qualitative study aims to explore the opinions of ECDs in Nigeria on the causal/predisposing factors of BO, effects of BO, and strategies for mitigating BO among ECDs in Nigeria.MethodUsing purposive sampling method, two sessions of focus group discussions (FGDs) involving 14 ECDs (key informants) holding key leadership positions and who were delegates of other ECDs in Nigeria were conducted to explore their experiences on psychological issues among ECDs. Data collected were transcribed and analyzed thematically.ResultsBO is an issue of serious concern among ECDs in Nigeria. The causes of BO are diverse, some of which include low staff strength, prolonged work hours, wrong counseling, lack of job description and specification, and abuse of powers by trainers. In order to mitigate the issue of BO among ECDs, the respondents recommended that work policy review, medical workforce strengthening, stakeholder dialog on ECDs’ welfare, regular psychological review of ECDs, and provision of free yearly medicals need to be looked into. Conclusion: Our findings revealed that the participants considered BO issues among ECDs to be common, and it affected their performance and the overall quality of care in Nigeria health system. Based on our findings, there is an urgent need to mitigate the problem of emotional exhaustion among ECDs in Nigeria.
