Abstract

This study aims to determine the characteristics of soil pores and therelationship of pore characteristics with soil permeability. Soil samples were collected from Punagaya Village, Bangkala District, Jeneponto Regency, South Sulawesi. Soil samples were taken from 20 observation points representing two types of land use ie cultivated land and fallow field at a depth of 0-60 cm. Soil analysis (pH, organic material, C-organic, cation exchange capacity, bulk density and soil texture), Pore characteristics(porosity, pore distribution and pore stability), and permeability. Analysis of soil properties and pore characteristics was descriptive, while the relationship between pore characteristics and permeability was analyzed by single or multiple regression and correlation analysis. The results showed that the permeability of soil vertisol 0.29 cm/h (slow) and the average value of soil pore characteristics of vertisol as follows: porosity ranged 56.49%, fast drainage pore 4.35%, water pore available 17.8% And 32.5% micro pores, and 36.46% pore stability. Based on the regression and correlation test, it is known that Porosity and porosity and pore stability index have the greatest influence on permeability.

Abstract

Ketersediaan fasilitas kesehatan di Kabupaten Mamuju bisa dikatakan cukup baik. Namun banyaknya jumlah fasilitas kesehatan di Kabupaten Mamuju tidak menjamin akan kualitas pelayanannya. Lokasi sangat erat kaitannya dengan pelayanan publik. Rumah sakit yang baik adalah rumah sakit yang aman dari kawasan bencana alam. Terdapat empat variabel dalam penelitian ini yaitu : potensi rawan banjir, potensi rawan bencana longsor, potensi rawan gempa dan potensi rawan tsunami. Adapun Analisis yang digunakan dalam penelitian ini adalah overlay analysis.  Berdasarkan hasil analisis yang dilakukan didapatkan bahwa ke-4 lokasi rumah sakit berada di kawasan rawan bencana dengan potensi bencana tinggi terutama untuk bencana gempa, bencana longsor dan bencana tsunami. Olehnya itu lokasi rumah sakit yang berada di Kabupaten Mamuju perlu ditinjau ulang kembali.

Abstract

Mangrove ecosystem is a habitat of various fauna, especially macrozoobenthos. The changing vegetation of the mangrove ecosystem will influence the abundance of macrozoobenthos. This study was conducted in April-August 2019 and aims to analyze the dominance and density relations of mangrove vegetation against the abundance of Macrozoobenthos on the Pagkajene coast. The research location is conducted on three stations, each station is divided into two sampling areas, and on each sampling area is placed six sampling points. Data collection of mangrove vegetation is used with a multilevel plot method and Macrozoobenthos using a plot 50x50 cm. correlation the dominance and density of mangrove vegetation towards the abundance of macrozoobenthos used linear regression analysis. The results of the study gained that the mangrove vegetation dominancy positively affects to the abundance of macrozoobenthos but insignificant. Meanwhile, the density of mangrove vegetation significantly negatively affects to the abundance of macrozoobenthos.

Abstract

RTH in urban areas has undergone many changes into built-up land so that it has changed its function into settlements, hotels, restaurants and others due to the very high growth of urban activities in Makassar City. Cemeteries have the main function as a place of public service for the burial of bodies. Cemeteries can also function as green open spaces to add to the beauty of the city and can function as water catchment areas, protectors, ecosystem supporters, and unifying urban spaces. The research aims to determine the design of the appropriate burial area model that functions as green open space and determine the potential of green open space that can be maximized from the Makassar City cemetery area. Research using survey techniques and descriptive analysis of 7 TPUs in Makassar City, was carried out from July to August 2021. The results show that dense cemeteries with high land cover have reduced the function of TPU as City Green Open Space. The design of the TPU in the context of optimizing the green open space increases the capacity of the tomb and improves environmental functions and religious norms, through the addition of facilities and diversity of vegetation.
