Canal transportation becomes one of the solutions to reduce traffic problem in Makassar. ABSTRAKTransportasi kanal menjadi salah satu solusi untuk mengurangi permasalahan kemacetan di kota Makassar. Oleh karena itu, untuk mengetahui seberapa besar potensi demand dari moda angkutan berbasis waterway di Kanal Panampu dan Jongaya, faktor-faktor yang mempengaruhi kesediaan menggunakan kanal sebagai media transportasi, serta mengidentifikasi preferensi user terkait perencanaan kanal sebagai media transportasi, dan sejauh mana peran kanal menjadi alternatif media transportasi. Dengan pendekatan kuantitatif deskriptif untuk mencapai tujuan tersebut, maka digunakan metode crosstab analysis, multinomial logistic regression dan stated preference. Dengan demikian, ditemukan empat variabel yang secara signifikan mempengaruhi kesediaan responden untuk menggunakan jasa angkutan berbasis kanal/waterway, yaitu income per bulan, waktu tempuh, alasan memilih moda, dan toleransi tarif. Sementara itu, analisis stated preference, menemukan jika transportasi waterway akan menyebabkan beralihnya pengguna moda berbasis jalan raya, kenaikan tersebut sebesar 31,10% untuk skenario 1 dan 37,26% untuk skenario 2.

The stipulation of the Palopo City Regional Tourism Development Master Plan 2021 – 2025 makes the Palopo City tourism sector quite optimistic after the beginning of the pandemic. Until 2030, Palopo City targets 250,000 domestic tourists and 1800 foreign tourists. The tourism potential of Palopo City, especially in urban areas is quite promising with the construction of a culinary center and souvenirs, public space activities, and the development of culinary businesses. These potentials must be supported by adequate facilities and infrastructure, including accessibility. Meanwhile, public transportation in Palopo City is considered inadequate and not integrated with each other. The concept of Palopo City Tourism offers the integration of tourism activities in the urban areas of the city of Palopo by providing integrated tourism transportation modes, equipped with supporting infrastructure such as bus stops. However, the implementation of the concept will be constrained by funding problems given the limited regional finances and the demand to prioritize sectors that are more strategic than tourism. This paper will see how the implementation of the PPP scheme in the tourism sector, especially in the transportation aspect, namely in the concept of Palopo City Tourism, both in development, operation and potential benefits. From the results of the analysis of movement patterns and the location of tourist objects, 3 optimal routes were chosen that could accommodate the movement of tourists, namely the southern route, western route and northern route. From the results of the analysis of infrastructure needs, it is necessary to develop infrastructure in the form of shelters and pedestrian paths and their accessories at tourist attraction points and several commercial areas. In addition, several PPP financing schemes are also proposed which are considered suitable for the City Tour Palopo concept, including Concessions and Affermage/Lease schemes, such as Service Contracts and Management Contracts, Design-Build-Finance-Operate/Maintain (DBFO, DBFM or DBFO). /M), Build-Own-Lease-Transfer (BOLT).

High consumption of freshwater and natural aggregate in concrete production becomes a matter of some concern that has been discussed recent years. An alternative partially or totally replacement for both materials is significant issue to reduce the negative impacts on the environment. Therefore, the aim of this research is to observe explicitly the effect of using seawater as mixing combined with recycled coarse aggregate and other material to make new recycled aggregate concrete (RAC) under compressive load. The experimental laboratory test was conducted to total of thirty cylinders specimens of two to groups of mix design with w/c of 0.45. First was three types of percentage level of recycled coarse aggregate with targeted compressive strength of 25 MPa. The second was two types of mixtures and totally replaced by recycled coarse aggregate with targeted compressive strength of 30 MPa. Some specimens were mixed by seawater and all were placed in the freshwater-curing during some definite period of 7 and 28 days. The results show that the seawater and recycle aggregate were not significant influence to reduce the compression strength for first mix category, while the second mix category was having great influence up to 22% at 28 days. The reduction in compressive strength increases with an increase the targeted compressive load.

The safety aspect, especially the fire disaster, is essential for Makassar City because of its role as a metropolitan city and a center of activity in the Eastern Indonesia Region. The dense population and activities make Makassar City vulnerable to fires. A vulnerability assessment can assist in urban disaster management, especially in highlighting areas of fire disaster mitigation.Based on this urgency, this study aims to identify fire-prone areas in Makassar City. This study examines the fire vulnerability of Makassar City from population density, building density, frequency of previous fire events, fire fires, distance to the availability of clean water, and dangerous buildings. Fire susceptibility criteria are based on stakeholder assessments involving disaster experts, city planners, and firefighters through the Analytical Hierarchy Process. Spatial assessment using multi-criteria analysis through the Simple Additive Weighting method, which is integrated with the Geographic Information System to allow spatial weighting. The study results show that the western and northern parts of Makassar City are very prone to fires. This area is an early development area for Makassar City, characterized by a dense population and buildings with various activities.

One of the potential that can be used to solve the congestion problem that occurred in the city of Makassar is by utilizing channels as urban transport medium. Makassar City has three channels with an overall length of 15.11 km, which two of them can be used as a water transport medium. The channels consist of Jongayya Channel (7.83 km), and Panampu Channel (4.92 km). Channel transportation can be one solution to reduce the congestion problems that occurred in the city of Makassar. The purpose of this study is to determine demand potential of waterwa y-based transport modes on Channel Panampu and Jongaya, factors that affect the willingness to use channel as a transportation medium, to identify user preferences related to channel planning as a transportation medium, and to identify the extent to which the role of the channel to become alternative transportation medium. To achieve these objectives, this study used a descriptive-quantitative methods approach. And were subsequently used crosstab analysis method, multinomial logistic regression and approach with stated preference methods.
