Abstract

Karbon monoksida (CO) merupakan racun yang cukup lama dalam sejarah manusia. Sumber utama dari CO adalah asap knalpot kendaraan terutama mesin berbahan bakar bensin yang tidak bisa dihindari bagi masyarakat yang berada di terminal maupun sekitarnya. Jenis penelitian ini adalah deskriptif yang bertujuan untuk mengetahui kadar karbon monoksida (CO) di terminal Karombasan Kota Manado. Pengukuran dan pengumpulan data dilakukan secara langsung dilapangan dengan menggunakan alat Gas Sampler Ambient. Hasil penelitian membuktikan bahwa kadar karbon monoksida di 3 titik pengukuran pada pengukuran I yaitu titik 1 = 0,237µg/Nm3, titik 2 = 0,184µg/Nm3, titik 3 = 0,152µg/Nm3, dan pada pengukuran II yaitu = titik 1 = 0,148µg/Nm3, titik 2 = 0,241µg/Nm3, titik 3 = 0,271µg/Nm3. Kesimpulan : Kadar karbon monoksida (CO) di terminal Karombasan tidak melebihi baku mutu udara ambien yaitu 30.000µg/Nm3 yang mengacu pada Peraturan Pemerintah No. 41 Tahun 1999 tentang baku mutu udara ambien nasional.

Abstract

Lighting is one of the important factors in the design of a space. A good school should be designed so as to improve the effectiveness of the teaching and learning process. Indonesia National Standard in 2000 classroom lighting is 250-300 lux. Measurement of Learning Fatigue was performed in 79 students of Class XI IPA using Reaction Timer tool and measurement of lighting intensity in 6 Classroom XI IPA by using Lux meter tool. The purpose of this study to determine whether there is a correlation of the intensity of lighting to the exhaustion of students studying Class XI IPA in SMA Negeri 1 Airmadidi. This research is analytic by using Cross Sectional approach that is researcher looking for correlation between independent variable (risk factor) with dependent variable (effect) by doing momentary measurement. The Intensity of Eligible Lighting is in class XI IPA VI with result 251 Lux and Student who is not tired there are 28 student and less tired as much as 51 student. To test the significance of the results obtained p value = 0,000 <value of α (0.05), thus Ha accepted and Ho rejected means there is a relationship between lighting intensity with Fatigue Student Learning Class XI IPA in SMA Negeri 1 Airmadidi Regency North Minahasa Year 2018. For further researchers measurement of lighting in the classroom is more appropriate to use local lighting that is measured directly on the table of each student's learning.

Abstract

Disposing of detergent waste into water bodies, both rivers and sea will affect biota in water, as the results of stated that the effect of laundry waste on nila mortality has a significant influence and differences in each concentration. A research on the design of appropriate technology for processing laundry waste (detergent) is required by using a combination of limestone and coconut shell filter media. The purpose of this study was to determine the ability of limestone and coconut shell filter media to reduce detergent content, pH and TSS in wastewater. Quasi-experimental research methods with pre-test and post test design. Population and research samples are waste taken from laundry waste. The research data will be analyzed univariately in a descriptive and bivariate form with statistical analysis using the T-test. The results of the study laundry processing (detergent) using limestone and coconut shell media can reduce the content of detergents (39.75% - 67.14%), pH (0.89% - 4.68%) and TSS (0.00% - 96.72%). T test results show that there are very significant differences before and after treatment, meaning that waste treatment can reduce the content of detergents in laundry wastewater.
