Abstract

Penelitian ini bertujuan untuk menganalisis perilaku masyarakat terhadap pengelolaan sampah impor dengan melihat secara keseluruhan dari faktor-faktor yang mempengaruhi perilaku masyarakat, dampaknya terhadap aspek sosial ekonomi dan lingkungan serta respon yang ditimbulkan. Metode yang digunakan adalah studi kasus dengan analisis deskriptif yang menggunakan berbagai sumber data sekunder. Data utama penelitian ini berdasarkan dari “Report: Sampah Plastik Meracuni Rantai Makanan Indonesia” oleh Arisandi et al. (2019). Fenomena sampah impor plastik ini telah mengubah pola perilaku masyarakat setempat, yang awalnya memiliki mata pencaharian sebagai petani tanaman musiman menjadi ‘petani sampah’ karena memberikan keuntungan yang jauh lebih besar. Hasil studi yang dilakukan oleh Arisandi et al. (2019) menemukan bahwa kadar dioksin 70 kali pada telur ayam di atas batas toleransi asupan harian yang ditetapkan oleh BPOM. Selain itu, penelitian lainnya juga menunjukkan bahwa terdapat pencemaran lingkungan pada kontaminasi tanah, pencemaran air tanah dan pencemaran Sungai Brantas. Tujuan dari studi kasus ini adalah untuk menganalisis faktor penyebab fenomena perilaku dan dampak sosial ekonomi dan lingkungan, sehingga hasilnya dapat diambil sebagai pembelajaran agar tidak ada kasus yang sama terjadi. Mengacu isu yang terjadi di Desa Bangun dan Desa Tropodo, mahasiswa dan pemerintah setempat telah memberikan respon berupa advokasi dari mahasiswa untuk penggantian bahan bakar dan menyumbang kayu bakar. Advokasi tersebut direspon oleh pemerintah setempat dan menghasilkan deklarasi bersama 47 pengusaha, deklarasi tersebut berisi komitmen untuk penggantian bahan bakar dan pengajuan kerja sama dengan Pertamina dan PGN. Oleh karena itu, diperlukan adanya peninjauan ulang terkait komitmen yang dibuat oleh 47 pengusaha tahu dengan Bupati Kabupaten Sidoarjo yaitu apakah komitmen yang dibuat benar-benar telah dijalankan dan kerja sama yang diajukan oleh Walikota Sidoarjo dengan PGN telah berjalan.

Abstract

The Mandalika Special Economic Zone (KEK) is a super priority destination in NTB with an increasing number of tourists visits every year. The increasing number of tourist visits affects the sanitation of the area. Sanitation conditions are influenced by tourist behavior. This study aims to analyze the sanitation behavior of tourists, especially in the use of clean water and toilets. The research method uses a questionnaire distribution to 96 tourists taken by simple random sampling. Determination of the number of respondents using the Slovin formula. The validity and reliability test of the questionnaire instrument was carried out first before the data was analyzed descriptively. The results of the study showed that 61% of respondents who had clean water use behavior in the Mandalika KEK had water use behavior in the "Good" category, while 39% had "Less Good" behavior. Toilet use behavior showed that 67% of respondents who had toilet use behavior in the Mandalika KEK had water use behavior in the "Good" category, while 33% had "Less Good" behavior.

Abstract

The dr. R. Soedjono Regional General Hospital Selong East Lombok is a government-owned health service facility that has experienced an increase in accreditation status to a class B hospital. The calculation of waste generation and waste sorting at the hospital has never been carried out so that the waste management team cannot determine a waste management strategy. Therefore, it is necessary to conduct research to analyze waste generation at the dr. R. Soedjono Regional General Hospital, East Lombok. A preliminary survey was conducted to determine the techniques and schedule for collecting waste data and waste producers. Waste data collection was carried out using the load count method every day for eight days. Data collection on the daily number of people producing waste was carried out through document searches. The waste producers in question include employees, medical personnel, patients and visitors. Data were analyzed descriptively to describe waste generation and its composition. The results show that the generation of domestic solid waste at the dr. R. Soedjono Regional General Hospital, East Lombok, which was observed every day for eight days was 0.3705 kg/person/day. Waste generation fluctuates every day of the week and the highest waste generation occurred on Sundays (holidays), where the number of people producing waste was dominated by patient visitors. Domestic solid waste in the hospital is dominated by plastic waste (36%), leftover food and leaves (31%), paper (15%) and other (11%). Others include diapers, sanitary napkins and bandages. Other waste components that were also found but with a much smaller weight percentage were wood, fabric or textile, metal and glass.

Abstract

The development of shade trees on the Mataram University campus is intended to maintain environmental comfort, as well as add beauty. The microclimate softening function of trees is largely determined by the density of their canopies, known as the leaf area index (LAI). Various LAI measurement methods have been developed, which are generally more suitable for assessing tree productivity but less valid for assessing the ability to soften the microclimate or decrease the discomfort index (DI). This study was conducted to analyze the distribution of LAI of shade trees and their relationship with the DI on the Mataram University campus. To obtain a more valid LAI value, the leaf area variable measured was the leaf area forming the canopy, replacing the leaf area on the canopy surface, as was done in previous studies. Microclimate variables measured to determine the discomfort index (DI) were air temperature and relative humidity. The results showed that the LAI of 108 trees (33 species) spread across 9 zones within the Mataram University campus ranges from 1.2630 (very small category) to 9.6735 (very large category). The DI values under the canopy of trees ranged from 23.225 (quite comfortable category) to 26.869 (somewhat comfortable category). The relationship between LAI of shade trees and DI on the campus of Mataram University was linear and negative, with the resulting regression equation being y = 28.1204-0.4749x. If LAI increased, then DI tended to decrease; conversely, if DI increased, then LAI tended to decrease. The function of campus trees in softening the microclimate can be enhanced by improving their LAI.

Abstract

This study aims to analyze the waste disposal behavior of visitors to Loang Baloq Beach, Mataram City, and the factors influencing it. This study used a quantitative descriptive approach involving 35 respondents selected through accidental sampling in December 2025. Data were collected through a closed-ended questionnaire using a Likert scale, field observations, and documentation, then analyzed descriptively through frequency calculations, percentages, and average values. The results showed that most respondents had a very good level of hygiene knowledge, but proactive behavior in maintaining cleanliness was still low. Basic behavior of disposing of waste in the proper place was high, while advanced behaviors such as picking up trash, bringing home recyclable waste, and reprimanding violators were still rare. This condition was supported by limited trash bin facilities, a lack of warning signs, and a lack of supervision at the study site. These findings indicate a gap between knowledge and practice of hygiene behavior in the Loang Baloq Beach area.

Abstract

The micro-scale tofu-tempeh industry in Abian Tubuh Baru Village has a strategic economic role, but its production activities produce liquid waste with a high organic load that risks degrading the aquatic ecosystem. This study aims to analyze in depth the behavior of micro-business actors in liquid waste management, as well as the community's social response to waste disposal in the Abian Tubuh Baru Village Watershed. The research method used is descriptive qualitative with a case study approach. Data were collected through field observations and in-depth interviews with business actors and the surrounding community who were selected purposively until data saturation was achieved. Data analysis was carried out thematically using the Miles & Huberman interactive model. The results showed that liquid waste is still discharged directly into water bodies without treatment due to the persistence of habitual factors, limited environmental literacy, and the absence of waste processing infrastructure facilities. This condition causes a significant decline in river water quality, characterized by changes in physical parameters (color and turbidity), and the emergence of a pungent odor due to organic decomposition. The community shows a tendency to act passively through environmental normalization by choosing to stop using river water rather than carrying out social control. These findings imply the urgency of community-based environmental awareness-building interventions for sustainable river pollution mitigation.

Abstract

Single-use plastic remains a major pollution problem in the campus environment. This study aims to analyze the single-use plastic consumption behavior of students in the Faculty of Mathematics and Natural Sciences (FMIPA) at the University of Mataram based on the Theory of Planned Behavior (TPB), including attitudes, subjective norms, perceived behavioral control, intentions, and actual behavior. This study used a descriptive quantitative approach, with 94 students selected through stratified random sampling from six study programs as respondents. Data were collected using a 1–5 Likert scale questionnaire and analyzed descriptively. The results showed that all TPB constructs tended to be in the moderate category, indicating that environmental awareness has been established but has not yet developed into consistent behavioral habits. A similar trend was seen across attitudes, subjective norms, perceived behavioral control, and actual behavior. The Environmental Science Study Program consistently scored higher than other study programs, indicating that an ecologically based academic culture plays a crucial role in establishing stronger social norms, thus enabling environmentally conscious behavior to be realized.
