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 Mataram University campus has shade trees in almost all area units, some of which are still quite ideal and some of which show problems with tree architecture deviations, such as trunk declivity and canopy inclination, which can cause the risk of tree fall. This study was conducted to analyze the distribution of tree fall risk based on tall, trunk declivity and canopy inclination on the Mataram University campus. The sample area was taken using the purposive sampling method and then sampling trees in each sample area unit using the quarter method. Tree variables observed were tall, trunk declivity and canopy inclination. The data were processed respectively to produce tree tall, trunk declivity, and canopy inclination classes. These data were then further analysed in an integrated manner to produce a value of tree-fall hazard risk. These tree-fall hazard values were interpreted into 5 categories, namely not hazardous, somewhat hazardous, quite hazardus, hazardous, and very hazardous. The results show that of the 108 shade trees on the Mataram University campus, 38.01% of the trees were in categories requiring immediate attention or action (moderately hazardous to very hazardous). Zone 1 was the only zone with the highest risk (0.93% very hazardous).

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.
