Abstract

Dyes such as batik dyes and the textile industry can pollute the enviroment, especially receiving water bodies. The use of pineapple biomass waste as an adsorbent for removal of waste dyes (methylene blue). Adsorption experiment using pineapple biomass were varied in the adsorbent dose, contact time and stirring speed. In this study, the pineapple biomass adsorbent used consisted of pure and activated pineapple biomass. The experimental result showed that the adsorbent masses were varied into 0,5,1,2,5,3, dan 3,5 gr 250 mg/L glass, that the adsorbent mass does not affect color removal. Where the highest removal efficiency was 68%. The activated pineapple biomass adsorbent (AA) adsorbed more methylene blue waste than the unactivated pineapple biomass adsorbent (AM). While the contact time at the time of the trial consisted of 5 variations with a time span of 30,60,90,120 and 150 rpm, it was found that the higher the stirring speed the heigher the increase in efficiency of the experiment, the highest stirring was 72% at the stirring speed of 90 rpm. The isotherm suitable for the adsorption of methylene blue waste is the langmuir isotherm which allows the adsorbent to occur physically or chemically and is limited to the monolayer layer. The high ability of pineapple biomass as an adsorbent after being activated can reduse methylene blue waste by an average of 70% in terms of the adsorbent period, contact time and strring speed.

Abstract

PERUMDA Tirta Muaro Unit Teluk Singkawang in the dimension of assurance is still not good. As evidenced by the low scope of service in this unit. Marked by the number of customers in 2020 as many as 2035 people. While the population of Sumay Subdistrict in 2020 as many as 21,398 people (Tebo Regency in Numbers, 2021). This means that the service coverage is 9.5%. This has not met the government's target of drinking water services of 75% for rural areas (Permen PU No. 13, 2013).This type of research includes explorative descriptive research using qualitative statistical research techniques. This research method uses survey method with customer population of PERUMDA Tirta Muaro Unit Teluk Singkawang. Sampling techniques using slovin formula. The analysis technique uses multiple linear regression analysis, with F test and t test using SPSS software. The results of the study that the level of customer satisfaction based on respondents' responses to 5 (five) dimensions of service quality received a score of 3.54 in the category of satisfied.

Abstract

Organic waste as a medium for maggot breeding to produce maximum compost yields. The quality and quantity of fly larvae breeding media greatly affect the nutrient content of the body and the survival of the larvae at the metamorphosis stage. This research is an experimental research model with a completely randomized design (CRD) consisting of 1 treatment. The treatment is given using selected organic waste. Analysis of the data in this study in the form of a table of results of laboratory analysis of compost characteristics, namely pH, C-Organic, N-Total and C/N ratio and maggot weight. The results of the Soil Test Laboratory are seen in the pH with rice, fruit and vegetable media experiencing differences in pH with values of 5.15, 5.5, 5.95 and 6.4 (acidic) looks different from the initial pH, in this test the pH value shows the medium used is quite good for the composting process. Table 4.2 also shows the difference in values at the time of testing, it can be seen from the 4 variations in C-Organic that the highest value in vegetable and fruit waste media reached 13.05 %, but did not meet the quality standards for good C-Organic values. for composting. In the N-Total the highest value is in the 4th variation with a value of 26.3 with an N-Total quality standard of 30% so that from the 4 variations of the media it does not exceed the N-Total quality standard which will affect the maggot weight, in contrast to C/N which has the highest value is the 4th variation with a value of 20, with the quality standard the best value of the C/N ratio in the composting process is 25-40%, and it can be concluded that the value of the C/N ratio has not met the quality standard of the C/N ratio so that affect maggot breeding with a span of 20 days.
