Abstract

Naturally hydrophobic films is currently receiving a lot of attention and has inspired efforts to create biomimetic surfaces. Application technology can be used as a water repellent coatings, for glass at a solar cell that can clean independently, so the use of outdoor solar cell can be used in a relative long period of time. In this study, the silica sol is made by making a solution of Na Silicate at 7%. and for the stabilization solution is used 1 M citric acid solution until a pH of about 2. Glass hydrophobic obtained by film coating on the glass test by means of dip coating, silica sol used is stabilized silica sol, glass coated silica sol are soaked in a surface-modifying agent that is TEOS, methanol, and n hexane in the ratio 1: 1: 1 volume ratio. The goal of treatment is to form silanol groups on the silica surface. The best hydrophobicity properties obtained on condition of Na silicate 7%, the modification time 2 hours at a temperature of 300C, the contact angle (Ө) of 128.40. The results of the study when compared to heating without microwave which takes 7 hours at 500C in terms of aspects of energy consumption, the use of the microwave can save energy by almost 85% to earn hydrophobic movie characters.

Abstract

The domestic Final Disposal Site (FDS) in Probolinggo City with 2 landfill areas is almost full, so it is necessary to develop a new landfill area as soon as possible. In the domestic FDS Bestari, there is still a large area for development, but some parts have been utilized by the management and the community. The aim of the study is to calculate the landfill area requirement over the next 10 years and development plan on limited land. The estimation of the amount of domestic solid waste in this study is based on a linear regression of the increasing of population, which is corrected by the amount of waste that can be transported to the FDS.  However, the activities in Probolinggo City are still dominated by settlements. With a reduction rate of 4 to 8%, the amount of waste that can be transported to the FDS in 2029 will reach 90 tons per day. With a heap height of up to 20 meters, the required land area for the new landfill area is ± 45000 m2. Taking into account the used area, 3 new small landfill areas and an extension of one existing landfill area proposed. This development area of landfill will be followed by new installation for leachate treatment.

Abstract

Cleaner Production (CP) practices comprised environmental strategy perpetually applied in the production, processes, and services to bolster efficiency, safety, and environmental friendliness. Some factors are to be considered to achieve a cleaner production strategy: stakeholders establishment, surveys, utilization, and impact, as well as how the top management devote their practices towards cleaner production. Combining with the mindset of sustainable stocks and resources, this exercise of cleaner production provides advantages of minimum toxic wastes and residues. In this study, we prioritize this practice to be applied in the aluminum industry, of which cleaner production action has not yet been employed. Small and medium businesses now no longer have enough monetary assets to put money into cleaner production practices because they require high-cost investment. This study aimed to determine the factors that have an impact on the application of cleaner production. The method used is regression analysis. The regression analysis results showed that three variables were tested to be significant and had a Root Mean Square Error (RMSE) value of 3.05 which means good. Three variables that affected the implementation of cleaner production include measurement of fuel usage, efforts to improve production process efficiency, and waste reuse by product. From the calculation results, the coefficient of determination (R2) was 0.550 (the influence was quite strong). The results of this study can be used as a recommendation for the government to increase the implementation cleaner production in Jombang Regency.

Abstract

The success of waste management cannot be separated from the community's participation. The community's involvement in waste management is still not significantly apparent. Community participation in rural waste management program was investigated in this study since the waste reduction activities still involve waste open burning and burying in the yard which is harmful for the environment. A research model was designed, and a questionnaire was distributed among 112 households (HHs) to analyze their participation in rural waste management programs. A semi-structured questionnaire survey, focus group discussions, and key informant interviews were adopted to acquire qualitative information. The analytical framework includes mass balance analysis (MBA) and Arnstein’s participation (APL) ladder. MBA was applied to measure the current waste reduction rate of each HH, while APL was used to evaluate community participation level in this program. The findings reveal that the average waste reduction is 0.48 kg/HH/day, contributing to a total waste reduction of 17.94 kg/day in the village (24.39% of total waste generation). Measurement using APL unfolds that the extant community participation in Mojosari Village, Bojonegoro Regency, corresponds to a non-participation continuum where villagers are misled by pseudo and tokenistic participation leading to unequal benefit-sharing. Based on these findings, the researchers challenge that communities’ engagement in rural waste management mainly relies on community cadres concerning environmental subjects as well as communities’ economic background. It is concluded where economically weak communities and manipulative figures exist, ensuring a higher community participation level is more challenging
