Abstract

The mining industry in Watusampu Subdistrict boosts local incomes but also brings socio-economic and environmental challenges. Mining provides jobs and higher wages but causes environmental degradation and air pollution leading to health issues. This study aims to analyze the influence of income on consumption patterns of workers in the mining sector in Watusampu Subdistrict. This sector has unique characteristics, especially regarding worker income levels, which can influence spending patterns. The method used in this research is quantitative with a survey approach, involving a sample of workers from various job levels in a mining company. Using simple linear regression analysis tools, this study explains the influence of income on consumption, both for food and non-food goods, among mining sector workers in Watusampu Subdistrict. The research results show that income has a positive and significant influence on expenditures for food and non-food items. Based on the research results, the regression equations obtained are: Y = 230,543.653 + 0.258X, Y = 170,503.477 + 0.361X, Y = 922,634.574 + 0.329X, Y = 212,953.571 + 0.557X. The regression coefficients indicate that income increases will increase expenditures, with a larger proportion directed toward non-food goods.

Abstract

ABSTRAKKenaikan karbon menyebabkan terjadinya pemanasan global yang berakibat perubahan iklim berupa fluktuasi curah hujan yang tinggi dan kenaikan muka laut. Lamun menjadi salah satu tumbuhan laut berkemampuan menyerap dan memindahkan jumlah besar karbon dari atmosfir setiap harinya, dan mengendapkannya dalam jaringan atau sedimen untuk waktu yang lama, sehingga keberadaan lamun di bumi sangat diperlukan sebagai jasa dalam penyerapan karbon. Penelitian ini bertujuan mengetahui kerapatan lamun, frekuensi kehadiran, biomasa lamun, cadangan karbon dan parameter lingkungan. Pengambilan sampel menggunakan metode line transek kuadrat. Lamun sebanyak 8 spesies ditemukan pada perairan Rumaat. Kerapatan lamun tertinggi berasal dari spesies Thalassia hemprichii sebanyak 5974 ind/m2. Frekuensi kehadiran Enhalus acoroides sebanyak 93,53% lebih tinggi dibandingkan spesies lainnya. Enhalus acoroides memiliki biomassa tertinggi sebesar 75.871,2 (g/m2) dan didominasi pada bagian bawah substrat. Lamun Enhalus acoroides memiliki total kadar abu 92,38% dan total kandungan organik 220,96% lebih dibanding spesies lainnya serta cenderung tinggi pada bagian bawah substrat. Cadangan karbon lamun di lokasi penelitian cukup tinggi terutama dari spesies Enhalus acoroides sebesar 1,04 ton. Paramater lingkungan di lokasi penelitian diperoleh suhu 32°C, salinitas 30 ‰, pH 8 dan DO 8 mg/l dan dapat dikategorikan cocok bagi pertumbuhan lamun.Kata kunci:  karbon, lamun, rumaatABSTRACTThe increase in carbon causes global warming which results in climate change in the form of high rainfall fluctuations and sea level rise. Seagrass is one of the marine plants that can absorb and transfer large amounts of carbon from the atmosphere every day, and deposit it in tissues or sediments for a long time, so that the existence of seagrass on earth is very necessary as a service in carbon absorption. This research aims to determine seagrass density, frequency of presence, seagrass biomass, carbon reserves and environmental parameters. Sampling used the quadratic line transect method. As many as 8 species of seagrass are found in Rumaat waters. The highest seagrass density came from the Thalassia hemprichii species at 5974 ind/m2. The frequency of presence of Enhalus acoroides was 93.53% higher than other species. Enhalus acoroides had the highest biomass of 75,871.2 (g/m2) and was dominated at the bottom of the substrate. The seagrass Enhalus acoroides has a total ash content of 92.38% and a total organic content of 220.96% more than other species and tends to be high at the bottom of the substrate. Seagrass carbon reserves at the research location are quite high, especially from the Enhalus acoroides species, amounting to 1.04 tonnes. The environmental parameters at the research location were temperature 32°C, salinity 30‰, pH 8 and DO 8 mg/l and could be categorized as suitable for seagrass growth.Keywords: carbon, seagrass, rumaat

Abstract

The number of activities affected by the current pandemic has disrupted community activities, one of which is in the world of education. Several factors have been affected by this pandemic, especially the online learning system and attendance system. Student attendance is one of the important factors in the world of education for the formation of quality and student discipline. In-depth and detailed information about student attendance can determine the quality of student learning. Currently, students at SMK Negeri 2 Balikpapan are still doing attendance manually via google form which is where the google form itself is universal that can be accessed by many people, therefore to maintain attendance data so that it can only be accessed by certain people, an application is made to perform attendance where this application can detect the location of students when doing attendance. The student's location can be obtained by creating a specified location point and adding a distance radius that will serve to validate student attendance information. Making this web application begins with analyzing the needs of the web application to be made, then designing the web display using whimsical, creating a database design, creating PHP program code, and finally implementation. The result of the implementation of the web application that has been made is that this web can run well according to the design that has been made
