“…This is because organic-based inhibitors have atomic compounds (N, P, O, S) in the DZP extract which are useful as ligan and can combine with metal surface and maintain the adsorption process in the ideal concentration. Thus, corrosive reaction can be minimized [26], [27]. However, the ASTM A36 carbon steel surface with inhibitor has a spot that can absorb the compounds, so it is possible to decrease the reaction rate.…”

Many natural resources from agricultural waste are used as inhibitors, one of which is Durio zibethinus. The systematization of the electrochemical experiment and morphology characterization were performed to analyse the corrosion inhibitor characteristics. The adsorption was calculated to help further understand the inhibition mechanism. The electrochemical results showed that the inhibitor extract acted as a cathodic type, with inhibition efficiency up to 75.05% using the method of PDP and 64.69% using the method of EIS. Based on the investigation of corrosion inhibitors, the adsorption isotherm agreed with the experimental results. The EIS data confirmed the chemical reaction and physical adsorption processes of the multi-component corrosion of DZE inhibitor. The results revealed the potential use of DZE inhibitors in applications such as desalination plants. Further, the improvement in performance was conducted through the use of synergy effects.

“…Berpikir positif menghadirkan sikap optimis dan harapan yang akan memberikan pengaruh terhadap perilaku individu untuk menjadi lebih baik (Karimi et al, 2019). Berpikir positif akan mengahadirkan keinginan yang positif juga, dengan senantiasa melakukan pembiasaan berpikir positif maka individu akan mendapatkan mana yang paing baik dan mana yang paling buruk dalam hidup ini (Haryono, 2000).…”

The purpose of this study is to evaluate the impact of students' positive and creative thinking abilities on their learning outcomes. This research uses a quantitative approach with an ex post facto research design. The sample consists of 54 students selected from a population of 117 students at SMP Negeri 3 Camba using purposive random sampling technique. Data collection is conducted using a questionnaire to assess positive thinking ability, a test to assess creative thinking ability, and documentation of student learning outcomes. The data obtained is analyzed using multiple regression tests after fulfilling the prerequisite tests. The results of the study indicate that the students' positive and creative thinking abilities are in the moderate category with an average of 73.59 and 77.78, respectively. In addition, the students' mathematics learning outcomes are in the moderate category with an average of 73.93. Based on the hypothesis testing results, students' positive and creative thinking abilities have a significant effect on mathematics learning outcomes for eighth grade students at SMPN 3 Camba, both partially and simultaneously

“…The majority of residents in the Pacitan regency rely on PDAM to meet their daily needs, however as the dry season approaches, the PDAM water supply is insufficient to be supplied to all areas, so the community receives water allocations in turn [8]. At this time, the existence of springs is urgently required to increase the availability of clean water for communities [9], [10].…”

The Pacitan Karst region is well known to be one of drought area in the Pacitan Regency during the dry season. Consequently, during the dry season, springs from karst system are required as a water source for the daily life. The appearance of these springs are a result and advantage of the karst terrain, which contains potential groundwater resources. The purpose of this study was to investigate the origin and characteristics of spring’s water in the Pacitan karst region based on its isotope concentrations. This research was conducted by collecting groundwater samples from springs, dug wells, bore wells, and rivers in Pacitan Regency and analyzing their 18O and 2H concentrations. Information on the source of groundwater is thought to be necessary for sustainable groundwater protection planning (conservation). According to the results of the investigation, there are four categories of isotope ratio distribution. The pattern of 18O and 2H concentrations in the samples around the Local Meteoric Water Line (LMWL) shows that groundwater originates from the same elevation of the catchment area from where rainwater falls and has the same characteristics as rainwater or meteoric water.
