In 2018, diarrhea in Indonesia was classified as a potential endemic disease of Extraordinary Events which was often accompanied by death. Well water can be a medium for transmitting diarrhea in the community, this transmission can occur because well water is contaminated with E. coli. In addition, population density can be a factor in the occurrence diarrhea. This study aims to determine the spatial analysis of the distribution diarrhea cases with the overlay method, which was carried out by analyzing the distribution pattern using Average Nearest Neighbor and Spatial Autocorrelation Report. Of the 26 scattered cases, the results of spatial analysis related to the presence of E. coli showed that there was a relationship between the incidence of diarrhea cases and the presence of E. coli, whose distribution pattern was clustered. The level of risk the presence of E. coli in well water with other environmental risk factors (wastewater disposal facilities, latrines and garbage disposal) showed that the most points found were those with moderate risk. In addition, the results of spatial analysis distribution diarrhea cases with population density showed that there was no significant relationship between the distribution diarrhea cases and population density, the distribution pattern was random.
Lahan terbuka yang berkurang di daerah perkotaan memberi dampak terhadap sirkulasi udara. Keberadaan ruko-ruko yang berjajar di pinggir jalan tanpa memberikan ruang untuk tanaman dapat berdampak bagi kesehatan lingkungan. Observasi pada 4 Juni 2015 di salah satu rumah toko di Jalan Godean km 6,5, Sleman, memperoleh hasil pengukuran suhu, kelembaban dan kebisingan sebesar 40,2 °C, 35,7 % dan 86,2 dB(A), yang sudah melewati syarat yang ditetap-kan. Vertical garden adalah salah satu cara menanam tanaman yang tidak memerlukan banyak lahan. Penelitian ini bertujuan ini mengetahui pengaruh penerapan vertical garden tersebut ter-hadap perubahan suhu, kelembaban dan kebisingan pada halaman rumah toko di jalan Gode-an. Jenis penelitian yang dilakukan adalah eksperimen dengan rancangan post-test only con-trol group. Tanaman yang digunakan terdiri dari palem kuning, bambu kuning dan lidah mertua. Data dianalisis dengan uji t-test bebas pada α = 0,05. Hasil penelitian menunjukan bahwa dari sepuluh ruko sampel, suhu rata-rata turun sebesar 0,6 °C (1,97 %), kelembaban rata-rata me-ningkat sebesar 0,25 % (0,57 %), dan kebisingan rata-rata turun sebesar 0,959 dB(A) (1,297 %). Untuk parameter suhu dan kelembaban, tidak dijumpai adanya perbedaan yang bermakna antara kelompok perlakuan dan kontrol (nilai p masing-masing: 0,153 dan 0,873). Sementara untuk parameter kebisingan, ditemukan adanya perbedaan yang bermakna (nilai p = 0,048). Oleh karena itu, kepada pemilik rumah toko disarankan untuk menggunakan vertical garden sebagai pagar hidup dan sebagai salah satu upaya untuk menurunkan kebisingan.
