Abstract

Sisa material pada pekerjaan konstruksi merupakan suatu kelebihan material konstruksi dalam jumlah tertentu yang tidak menambah nilai apapun terhadap suatu pekerjaan konstruksi tetapi berdampak pada biaya pekerjaan konstruksi. Pada pelaksanaan pekerjaan Proyek Pembangunan PLTU Sul-Sel Barru-2, terdapat kegiatan pembangunan gedung PLTU dengan salah satu kegiatan utama adalah pekerjaan arsitektural yang menghasilkan sisa material yang merugikan proyek. Tujuan dari penelitian ini adalah untuk mengetahui jenis material yang memiliki volume dan biaya sisa material terbesar pada pekerjaan arsitektural, serta untuk mengetahui faktor-faktor timbulnya sisa material pada pekerjaan arsitektural.. Metode analisis yang digunakan adalah analisis statistik berupa analisis regresi linier. Hasil penelitian menunjukkan bahwa material yang menjadi sisa dalam proyek adalah material sisa pemasangan bata ringan, sisa pengerjaan plester serta sisa pemasangan keramik. Faktor-faktor timbulnya sisa material pada pekerjaan arsitektural yaitu pengawasan, keterampilan pekerja dan material yang digunakan tidak berpengaruh terhadap jumlah waste yang dihasilkan pada proyek, sedangkan faktor perencanaan merupakan satu-satunya faktor yang berpengaruh terhadap jumlah waste yang dihasilkan pada proyek pembangunan PLTU Sul-Sel Barru-2.

Abstract

The aim of the research is to obtain an overview of the condition of the Saddang River in order to manage the sand mining area, taking into account environmental, economic and socio-social aspects. Various studies show that river sand mining can provide direct and indirect economic benefits to local communities, as well as environmental damage to rivers. However, research on Saddang River sand mining is still very minimal. The data collection methods used consist of literature studies to collect various reading materials that support and support research, field surveys to obtain data directly from the field, presentation of question sheets (questionnaires) and interviews on issues that are in accordance with the research theme. Focus Group Discussion (FGD) to examine stakeholders and local communities. Physical condition of the river body and replenishment rate using UPTD data for the Saddang Watershed. Management with an integrated approach includes economic, environmental and social-social aspects, by combining two different paradigm approaches, namely positivistic and constructivist, which is believed to be able to produce a sustainable management strategy for sand mining activities in the Saddang River, Pinrang Regency.

Abstract

Freshwater mussels are not just another aquatic organism, they have a significant impact in the context of fisheries and freshwater ecosystems. As natural biofilters, freshwater mussels play a crucial role in maintaining water quality by absorbing and removing harmful substances, while providing an optimal environment for the growth of fish and other aquatic organisms. Although mussels have great potential as a diverse natural resource, currently their utilization is still limited to the use of mussel meat as food and mussel shells as decoration. Clam shells contain lime (Calcium carbonate CaO) so it is good to use in concrete mixing. The purpose of this study was to determine how the addition of clam shells affects the level of change in the quality and tensile strength of concrete. The method used is testing the tensile strength of concrete in the laboratory (experimental). The samples tested were samples with three variations of clam shell mixture, namely 0% shell (4 samples), 10% shell (4 samples) and 25% shell (4 samples). The stages of implementation include; making test samples in the form of concrete cylinders, treating test samples and testing tensile strength. The results showed an increase in concrete tensile strength at the addition of 10% clam shells with a tensile strength value of 2.03 Mpa and a decrease in concrete tensile strength at the addition of 25% clam shells with a tensile strength value of 1.24 Mpa. The ideal proportion of clam shell addition for concrete mixing in this study is 10% because it can increase the tensile strength of concrete.

Abstract

This research aimed to determine the social, economic, and environmental impact of Saddang River sand mining on local communities and the Pinrang district government. Primary data collection used field surveys to obtain supporting data on economic aspects consisting of production capacity, costs, selling price of sand at the miner level and market price at the consumer level, number of grains, and various other economic values such as indirect value and indirect use value. The primary data collection method uses a total sampling of 80 miners operating in the research area. Consumer data uses a field survey method with 8 hours of observation per day. Saddang River sand mining provides great socio-economic value and environmental impact, directly or indirectly. This significant socio-economic value and impact, if not accompanied by good management, can result in over-exploitation, which impacts the physical and ecological damage of the Saddang River. On the other hand, the high rate of sedimentation from upstream of the Saddang River results in shallowing, so sand mining activities help normalize the Saddang River. Therefore, to continue providing economic benefits and the Saddang River to avoid physical and ecological damage due to mining activities, sustainable management of Saddang River sand mining is needed.

Abstract

Beton merupakan bahan yang penting dan banyak digunakan dalam dunia konstruksi. Salah satu penggunaan beton yaitu perkerasan kaku (Rigid Pavement) yang terdiri dari plat beton semen portland dan lapis pondasi diatas tanah dasar. Dalam penelitian ini digunakan salah satu bahan pengganti agregat halus pasir sungai dengan menggunakan pasir laut.Penelitian ini bertujuan untuk (1) menganalisis besarnya kuat tekan beton yang menggunakan pasir laut sebagai agregat halus pada umur 7, 21 dan 28 hari, (2) mengetahui pasir laut layak digunakan sebagai agregat halus pada perkerasan kaku (Rigit Pavement) jalan pantai. Penelitian ini menggunakan metode eksperimental dengan total benda uji sebanyak 30 buah untuk benda uji kuat tekan berbentuk silinder dengan diameter 150 mm dan tinggi 300 mm dengan variasi pasir laut 0% (beton normal), 25%, 50%, 75% dan 100% pada umur 7, 21, dan 28 hari dengan fas sebesar 0,60. Masing-masing variasi berjumlah 6 benda uji. Berdasarkan hasil pengujian kuat tekan beton, terjadi penambahan kekuatan pada beton yang memakai pasir laut (variasi 25%, 50%, 75% dan 100%) pada saat umur 7, 21 dan 28 hari, tetapi selalu masih dibawah daripada kuat tekan beton normal (variasi 0% pasir laut). Kuat tekan terbesar terjadi pada beton dengan beton normal (variasi 0% pasir laut), yaitu sebesar 25,61 MPa pada umur 28 hari, sedangakn kuat tekan terendah terjadi pada beton dengan variasi 100% pasir laut, yaitu sebesar 16,98 MPa pada umur 7 hari

Abstract

The research aims to determine the characteristics of sand grain gradation, mud content and specific gravity of Saddang River sand. Saddang river sand is the main source of sand used in construction activities in South Sulawesi and West Sulawesi. In order to ensure that Saddang river sand meets the quality standards used in the construction world, it is necessary to conduct research related to Gradation of grains, mud content and specific gravity of sand. These three factors are part of the factors that determine the quality of concrete and cement mixtures. The research was located at the Saddang River sand mine in Pincara Village, Patampanua subdistrict, Pinrang Regency, South Sulawesi, Indonesia. The research method uses field surveys and laboratory analysis to analyze the gradation of sand grains, mud content and specific gravity. The results of the sieve analysis show that the Saddang River sand is classified as gradation zone no. 4 or classified as fine sand based on the fine aggregate gradation table SNI 03-2834-2000 and ASTM C-33. The results of the analysis of the Saddang River sand mud content ranged from 2.233% to 2.250%, fulfilling SNI 03-4804-1998 which has been determined at a maximum of 5%. The specific gravity analysis show the average value of bulk specific gravity (2,489 gr/m3), dry specific gravity (2,524 gr/m3), and visible specific gravity (2,600 gr/m3). meets SNI 03-1970-2008 standards ranging from < 1.6 gr/m3 to 3.2 gr/m3. The ater absorption in fine aggregate ranged from 1.5% to 3.8%, meeting SNI 03-1970-2008 with a maximum of 5%.
