Abstract

Sales are the main part of a company's operations, but sales that occur can increase or decrease sales (fluctuation) and cause sales losses. Sales losses can be anticipated by conducting sales analysis using Least Square, an index number that describes the factors that influence sales. The results of this research aim to predict sales of all products sold in 2022 by calculating Least Square and calculating index numbers to determine the increase or decrease in the percentage of sales levels from January to March 2022. The research found that (1) the percentage of sales levels in January until March 2022 there was an increase in sales of 1,323,850 units compared to sales in 2021, namely 550,058 units; and (2) the percentage of sales in January experienced an increase in sales of 19%, in February there was an increase in sales of 49% and in March there was a decrease in sales of -1%.

Abstract

Pembangunan infrastruktur di Provinsi Kalimantan Selatan akan terus meningkat khususnya pada Kabupaten Tanah Laut. Hal ini terjadi mengingat Kabupaten Tanah Laut merupakan Kabupaten yang direncanakan memiliki Kawasan Industri Strategis Nasional yang terletak di Kecamatan Jorong. Maka diperlukannya bahan material untuk mendukung pelaksanaan pembangunan kawasan industri tersebut. Selain itu, Kabupaten Tanah Laut dikenal dengan daerah penjual kayu galam yang sebagian hanya dipergunakan berupa batangnya saja dan untuk kulit kayu galam tidak ada nilai ekonomisnya hanya menghasilkan sampah yang biasa ditumpuk atau dibakar. Di Kecamatan Jorong juga terdapat Pembangkit Listrik Tenaga Uap (PLTU) yang menghasilkan limbah B3 dalam jumlah cukup banyak sekitar 120 ton per hari setiap pengoperasian PLTU tersebut. Diharapkan dalam pemenuhan bahan material pembangunan kawasan industri tersebut dapat memanfaatkan limbah yang ada di sekitar seperti beton geopolimer. Dalam pembuatan beton geopolimer dilakukan penggantian bahan baku semen oleh Fly Ash yang dicampurkan dengan alkali aktivator dan penambahan campuran dengan serbuk kulit kayu galam dengan perbandingan 74:26 antara Fly Ash dan alkali aktivator dalam bahan pengganti semen. Dan perbandingan antara Fly Ash dan alkali aktivator dengan serbuk kulit kayu galam sebanyak 75:25. Hasil dari analisa kuat tekan beton umur 28 hari didapatkan hasil rata-rata paling tinggi adalah kuat tekan campuran beton normal tanpa ada pengganti semen dengan Fly Ash dan serbuk kulit kayu galam sebesar 21,153 MPa.Kata kunci: beton geopolimer, Fly Ash, kuat tekan, serbuk kulit kayu galam

Abstract

Office of Koperasi, UKM, and Trade of Tanah Laut Regency, South Kalimantan conducts the health of Koperasi by manually checking the financial report data of each Koperasi. This study aims to determine the best Koperasi performance using a decision-making system with the Simple Additive Weighting (SAW) method. Performance evaluation is based on the criteria in the Technical Instructions for the Deputy for Koperasi Number 15 of 2021 concerning Guidelines for Working Papers on Cooperative Health Examination. The criteria to determine the best Koperasi performance were based on the attributes of the governance, risk profile, financial performance, and capital of Koperasi. The SAW method was used to select the best Koperasi by adding up each attribute, then multiplying by the weight of the related attributes. Based on the calculations using the SAW method, Koperasi 33 was selected, with the highest Vector value (V(i)) of 0.944719. Koperasi 33 can be categorized as the best of 100 Koperasi in Tanah Laut Regency, South Kalimantan.

Abstract

Determining the priority of road damage in road construction typically relies on assessments based on the Pavement Condition Index (PCI) method. However, the PCI classification does not provide specific criteria to distinguish between road sections within the same classification, complicating the identification of sections in worse condition. To address this issue, mathematical analysis can employ multi-criteria decision-making (MCDM) methods to prioritize road sections for repair. One effective approach is the integration of the Rank Order Centroid (ROC) and Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS) methods. The analysis results indicate that the road sections prioritized for repair were located at Location III: Alternative 70, Alternative 80, and Alternative 42. Based on the Pearson correlation coefficient between the ranking orders of the pavement assessment using PCI and ROC-TOPSIS, there is a 65% similarity. Consequently, ROC-TOPSIS can serve as an alternative method for determining priority repairs, as it aligns with the results of the road pavement assessment.
