Ph Level

One parameter of air quality is the level of turbidity and acidity. For most people, air quality is considered insignificant because it is inappropriate for aesthetics. Good water to be issued according to regulations issued by the government through the Minister of Health of the Republic of Indonesia has a pH value of 6.5 - 8.5 and the maximum turbidity level is 5 NTU (Nephelometric Turbidity Unit). Therefore the author makes a measuring device for acidity in water to facilitate the use of water that will be used by the community. Processing the measurement results is carried out by a pH sensor which will be processed by the Arduino Uno Microcontroller and produced with output via LCD (Liquid Crystal Display). In this test, the author uses several air samples that have been determined by the government, namely pH 4, pH 7 and pH 10. And from several other samples using water that is reasonably suitable for consumption with a pH level of 6.5 and above and can be used as Neutral.

Output Information

Tofu has the best quality vegetable protein because it has the most complete amino acid composition and is believed to have high digestibility (85% -98%). According to SNI 01-3142-1998 and SII No. 0270-1990 testing criteria for soy tofu based on smell, taste, color, appearance, or texture. Tofu soybeans are prone to physical or texture damage due to factors such as inappropriate pH levels and insufficient storage which results in damaged tofu. Therefore in this study, it is proposed to determine the elasticity of soy tofu with the parameters tested are the pH level in the manufacture of soy tofu, the storage temperature, and the capacitance value to see how thick the tofu is with a capacitive sensor using the capacitor principle. Where the parallel plate capacitor is a capacitor consisting of two parallel metal plates. The test results of all sensors are sent to the database and will be displayed on the page on the Android application which will provide real-time sensor output information to the user. Based on the results of testing on this system using a pH sensor, the pH value is around 3-4 which indicates that the pH level used is very good for use in tofu processing, at pH 4.56 with storage at 29 ° C the highest elastic capacitance value is 3.58.  In testing data delivery, the throughput value is 4336,217 b / s and the smallest delay value is 0.017ms because the smaller the delay value, the better the quality of data transmission because there will be no delay in sending data.

Ph Level

Shrimp culture is the fastest growing sector of the aquaculture industry in Malaysia. In culturing tiger prawn, the pH level needed for water is around 7.0-8.5. Currently, prawn farmer in Malaysia still using a manual method to control the water pH level by adding chemical (Lime), in which, the process required constant monitoring and control by labor. Since the prawns are so sensitive on pH level, an automatic pH control system is required to maintain the water pH automatically and precisely. This research was conducted to design a system that can control and provide feedback on the changes of pH level and been implemented at the reservoir tank that can act as water storage tank and prawn pond. Control system and pH sensor are the important components in controlling the pH level. Input from pH sensor was processed by controller. Moreover, after an error is detected by controller, the correction will be delivered to the system as a feedback process. Nitric acid with concentration of 0.001M was added to 25 liter water in tank 1 so that the pH level is decreased to pH 3.00. Different concentrations were used for slaked lime; 0.5M, 0.4M. 0.3M, 0.2M and 0.1M, to increase the pH from acid to slightly alkaline in the range of pH value 7.00-8.50. Slaked lime was pumped to Tank by water pump and it will stop if the pH level reaches the setting level. The time for the system to recover from pH 3.00 to 7.00-8.50 was recorded. The results shows that slaked lime with the concentration 0.5M has the fastest recover time which was 29s follow by 0.4M in 69s, 0.3M in 92s, 0.2M in 151s and 0.1M in 252s, respectively.

<span>A hydroponics plant can grow healthily with sufficient nutrient, temperature, light, humidity as well as pH level that is indeed vital in ensuring the plants will absorb maximum nutrient elements required. This paper presents automated monitoring and controlling pH levels for the hydroponic cultivation technique. In this study, automated monitoring and controlling of pH levels are developed specifically for the hydroponic cultivation technique. There are three main methods that involved in the development of the system namely hardware, programming and functionality test. Firstly, users need to set the maximum and minimum pH levels as required by the plant. Then, the pH sensor will monitor the real-time pH level of the water. A syringe pump that contains a pH up solution (alkaline) and a pH down solution (acid) will drip the solutions to neutralize the water content if the water pH level is not within the stated ranges as set by the user. Results showed that the automated monitoring and controlling pH levels were successfully developed and functionality was tested and confirmed as desired. The syringe pumps responded perfectly upon changes of the water pH value based on the validation done that showed 100% accuracy of the syringe pump responds. </span>

<p align="justify"><strong><em>Alcohol and pH levels in hand sanitizer are two things that need to be considered. The amount of alcohol content affects the level of effectiveness in killing germs, while the pH level is a factor that indicates whether the liquid is safe for human skin or not. HANDSIOT is a device to measure alcohol levels and pH in hand sanitizers. HANDSIOT is operated by testing the hand sanitizer liquid in the liquid container at the bottom. This device is made to be able to take measurements effectively and can monitor the measurement results in real-time using a smartphone. Gas chromatography and electrolysis methods were implemented using the MQ-3 gas sensor and the SEN0161 pH sensor. The gas chromatography method is used as a method of measuring alcohol content based on the evaporation of the alcohol. While the electrolysis method is used to measure the pH degree by measuring the amount of current flowing using two electrodes. In testing the accuracy of this tool by comparing the readings on the tool with an alcohol meter and also a pH sensor that is already available on the market</em></strong><strong></strong></p>

Oversight Body

The Ombudsman as an external oversight body for official performance, in Fikih Siyasah (constitutionality in Islam) is included in the supervision stipulated in legislation (al-musahabah al-qomariyah). Supervision is done so that public service delivery to the community is in accordance with the rights of the community. This is done because in carrying out its duties, officials are very likely to conduct mal administration, which is bad public services that cause harm to the community. The Ombudsman is an institution authorized to resolve the mal administration issue, in which one of its products is by issuing a recommendation. Although Law No. 37 of 2018 on the Ombudsman of the Republic of Indonesia states that the recommendation is mandatory, theombudsman's recommendations have not been implemented. This is due to differences in point of view, ie on the one hand in the context of law enforcement, but on the other hand the implementation of the recommendation is considered as a means of opening the disgrace of officials. Recommendations are the last alternative of Ombudsman's efforts to resolve the mal administration case, given that a win-win solution is the goal, then mediation becomes the main effort. This is in accordance with the condition of the Muslim majority of Indonesian nation and prioritizes deliberation in resolving dispute. Therefore, it is necessary to educate the community and officials related to the implementation of the Ombudsman's recommendations in order to provide good public services for the community, which is the obligation of the government.
