Ecotourism is an alternative to conventional tourism where tourists can enjoy natural scenery by prioritizing conservation aspects as a form of expressing responsibility to the environment. There are several popular ecotourism sites in Indonesia, one of which is Banyuwangi Regency, which was the world winner of the 12th United Nations World Tourism Organization (UNWTO) awards. This study was conducted to analyze the factors that influence the behavioral intention of tourists to ecotourism at Banyuwangi Regency. By knowing the factors influencing behavioral intention, tourism managers and local governments can gain better insight into strategies that can be adopted to increase consumers’ positive intention toward ecotourism. This research was conducted with multivariate structural equation modeling (SEM), and twelve hypotheses were tested. A total of 344 respondents participated. Six accepted hypotheses were revealed. A positive and significant influence was found on the subjective norm and destination image variables on ecotourism behavioral intention. The analysis found a positive and significant effect between ecotourism self-identity and subjective norm variables. Other results found that the biosphere value had a positive and significant effect on the environmental attitude, and the future time perspective and destination image variables were found to have a positive and significant effect on the environmental concern variable. Most respondents in this study admitted that they are individuals who have a love for nature and are willing to dispose of their garbage in its proper place. Further theoretical and practical implications were described.

According to PP 101 Year 2014, aluminum slag is classified as BTS waste in code B313-2 and thus, will bring chronicle effects. This research aimed at investigating the potentials of aluminum slag by analyzing the waste characteristics, solidification process, compressive strength, and TCLP of BTS waste solidification product. The results of research demonstrated that the slag contained BTS elements and based on PP 101 Year 2014, they must be managed, one of which is through stabilization/solidification. The process of using aluminium slag waste solidification in this research was conducted by crushing, grinding, sorting from aluminium dross and recovering metal via smelting. Slag has potentials for construction materials such as geopolymer concrete, concrete brick, pressed brick, and paving block. The best composition for using aluminium slag with solidification is less than 20% because the product will get leaching. The highest compressive strength of slag by 36.8 Mpa at X Ltd in Jombang was for paving block of parking area. In addition, TCLP test toward aluminium slag has fulfilled USEPA standard and it is safe for the environment in the long period.  Keywords: aluminium slag aluminium, solidification, compressive strength, TCLP

Humans need water for survive, one of which is for drinking. Before used for drinking purposes, it is require treatment first. In Surabaya, there is a Drinking Water Processing Installation that serves drinking water for the people of the city of Surabaya. This research aimed at predicting the quality status and water quality of Surabaya River by employing dynamic system and pollution index. The research used the water quality of the Surabaya river (Gunung Sari monitoring station) in 2014-2016, and prediction of water quality using the dynamic system method (stella) for 2017-2021. Based on the prediction results, it is known that the predicted values ​​of BOD, TSS, DO, PO₄ and COD do not exceed the standard except for NO₃. Based on the Pollution Index, the water quality of Surabaya River from 2017-2021: TSS is in the heavily polluted category; BOD, DO, and PO₄ in the lightly polluted category; COD and NO₃ in the safe category.

This research was conducted in automotive workshop of VEDC Malang and the samples were taken at the automotive machine and automotive electric workshops. The parameters which examined were the Pb concentration in the mouse blood (Mus musculus) in 2 and 3 months years old. The measurement was run for 5 times every 10 days, and the result was mean value of the increasing rate of Pb concentration in the mouse blood. The aim of this research was to determine the increasing rate of Pb concentration in the mouse blood which has the relation with different working area, different age, and also duration of exposure. Based on the data of laboratory test, research continued by T-test analysis, Simple regression test, and correlation, and also General Linear Model. By doing statistic analysis with the different working area, duration of explanation, and different age. Result of this research showed that there were the differences of rapid increasing of Pb concentration in both workshop. Generally the age which influence so much for that (in the mouse body) and have the relation with the body stamina. If the mouse body absorb amount of Pb constantly, so the Pb concentration in it will increase more and more and it cause the decreasing of the body height.
