The online trading system has become a common thing for today's society. Freight forwarding companies, whose job is to deliver goods from sellers to buyers, have an important role in online trading. One of the freight-forwarding companies is SiCepat Express Baleendah. The delivery route used by SiCepat Express Baleendah is not organized so it is often inefficient. This problem in Mathematics is known as the Traveling Salesman Problem and can be solved using the Cheapest Insertion Heuristic (CIH) Algorithm. Hence, it is necessary to know how to determine the route of delivery of goods using the CIH Algorithm, also, the comparison of results and efficiency between the routes obtained from the application of the CIH Algorithm and the routes used by SiCepat Express Baleendah. From the research, it was found that the total distance for shipping goods obtained using the CIH Algorithm with Python was 3,757 km, while the route from SiCepat Express Baleendah was 4.840 km. The application of the CIH Algorithm with Python is proven to provide a route with a total distance of 22.38% smaller than the total distance traveled by the route used by SiCepat Express Baleendah. \u0000Abstrak. Sistem jual beli secara online sudah menjadi hal yang umum bagi kalangan masyarakat saat ini. Perusahaan pengirim barang, yang bertugas untuk mengirimkan barang dari penjual ke pembeli, memiliki peran penting dalam jual-beli online. Salah satu perusahaan pengiriman barang adalah SiCepat Express Baleendah. Rute pengiriman barang yang digunakan oleh SiCepat Express Baleendah tidak terorganisir sehingga seringkali tidak efisien. Permasalahan tersebut dalam Ilmu Matematika dikenal sebagai Travelling Salesman Problem dan dapat diselesaikan dengan Algoritma Cheapest Insertion Heuristic (CIH). Berdasarkan hal tersebut perlu diketahui cara menentukan rute pengiriman barang menggunakan Algoritma CIH serta perbandingan hasil dan efisiensi antara rute yang diperoleh dari penerapan Algoritma CIH dengan rute yang digunakan SiCepat Express Baleendah. Dari penelitian didapatkan total jarak tempuh pengiriman barang yang diperoleh menggunakan Algoritma CIH dengan Python adalah sebesar 3,757 km, sedangkan hasil yang digunakan oleh SiCepat Express Baleendah adalah sebesar 4,840 km. Penerapan Algoritma CIH dengan Python terbukti memberikan rute dengan total jarak tempuh 22,38% lebih kecil dibandingkan total jarak tempuh rute yang digunakan oleh SiCepat Express Baleendah.","PeriodicalId":31272,"journal":{"name":"Jurnal Riset Pendidikan Matematika","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90096587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mangosteen fruit export is one of the fresh fruit export commodities from the agricultural sector which contributes to the country's foreign exchange. The increase in the country's foreign exchange is influenced by the increasing volume of mangosteen exports, so there needs to be special handling related to the quality of the mangosteen fruit to be exported. Analysis of the quality control of mangosteen exports can be done using Statistical Quality Control (SQC). Quality control analysis using SQC begins with forming a flowchart to review the flow and processes that will be carried out, then to make it easier to show and understand the data, check sheets and histograms are arranged. Based on the results of the analysis using the control chart p which shows that the damage that occurs is still outside the control limits at several intervals with an upper control limit of 0.068. The Pareto diagram shows that the most dominant damage was found in the size mismatch of the mangosteen fruit, which was 8197.5kg or 90.152% of the damage. Based on the scatter diagram, it is known that there is a very strong relationship, indicated by a correlation of 0.934 between the size discrepancy and the damage that occurs, while the discrepancy in the maturity level of the mangosteen shows a low correlation with a correlation of 0.305. This means that the size discrepancy has a very strong impact and the maturity level discrepancy has a low impact on the damage that occurs. In addition, by using a causal diagram, it is known that the factors that cause damage to the mangosteen fruit are caused by environmental factors and human factors. \u0000Abstrak.  Ekspor buah manggis menjadi salah satu komoditas ekspor buah segar dari sektor pertanian yang memiliki kontribusi terhadap devisa negara. Peningkatan devisa negara dipengaruhi oleh meningkatnya volume ekspor buah manggis, sehingga perlu adanya penanganan khusus terkait mutu buah manggis yang akan di ekspor. Analisis kendali mutu ekspor buah manggis dapat dilakukan dengan menggunakan Statistical Quality Control (SQC). Analisis kendali mutu dengan menggunakan SQC diawali dengan membentuk flowchart untuk meninjau alur dan proses yang akan dilakukan, selanjutnya untuk memudahkan dalam menunjukkan dan memahami data disusun check sheet dan histogram.

The economy of a region consists of various interrelated sectors. The linkages between sectors can be analyzed to determine which sectors have a high contribution rate to the economy of a region or are referred to as leading sectors. Determination of the leading sector for a particular year can be done through input-output analysis. The input-output tables used to analyze the leading sectors are not published every year, so the input-output tables for a particular year are sometimes obtained through the estimation method. There is technical coefficient matrix in the input-output table which states the total input ratio for a sector to the total output of other sectors. This study aims to estimate the technical coefficient matrix in Tegal Regency in 2020 using the RAS method. The estimation is based on the input-output table of Tegal Regency in 2016. The results of the technical coefficient matrix estimation are used to create a multiplier matrix which then analyzed to determine the leading sectors by calculating the dispersion power index and the sensitivity index of each sector. Based on analysis, it was found that the manufacturing sector and the construction sector are the leading sectors in the Tegal Regency area in 2020. \u0000Abstrak.

One way to minimize traffic queues is to use traffic lights with appropriate cycle time settings. The existence of traffic lights is very helpful to curb traffic, but there is still a less than optimal use of traffic lights. For example, in the traffic lane in the Pasteur area of ​​Bandung, determining which flow should be green or red first and how long it takes the lights to turn on in each color. One solution to solve this problem is through the point coloring approach of the Graph by implementing the Welch-Powell algorithm and support with Queuing Theory as a representation of the traffic light model. Using the information about the direction of the currents in the Pasteur junction, a graph can be formed and the point coloring is performed using the Welch-Powell algorithm. The results of the implementation of the Welch-Powell algorithm obtained the duration of one new cycle at traffic lights. Furthermore, the results obtained by testing with Queuing Theory where the results obtained that the duration of the new pasteur traffic light is more optimal than one traffic light cycle based on field data. \u0000Abstrak. Antrian lalu lintas menjadi permasalahan umum yang dihadapi berbagai kota di Indonesia. Salah satu cara meminimalisir antiran lalu lintas adalah melalui penggunaan lampu lalu lintas dengan pengaturan siklus waktu yang tepat. Keberadaan lampu lalu lintas sangat membantu untuk menertibkan lalu lintas, namun masih ada kasus penggunaan lampu lalu lintas yang kurang optimal. Sebagai contoh pada persimpangan lalu lintas di kawasan Pasteur Bandung, penentuan arus mana yang harus hijau atau merah terlebih dahulu dan berapa lama waktu lampu untuk menyala dalam masing-masing warna. Salah satu solusi untuk mengatasi masalah tersebut  adalah melalui pendekatan pewarnaan titik pada Graf dengan mengimplementasikan algoritma Welch-Powell serta dikaitkan dengan Teori Antrian sebagai representasi model lampu lalu lintas. Melalui  informasi tentang arah dari arus-arus yang berada dalam Persimpangan Pasteur, dapat dibentuk sebuah graf dan dilakukan pewarnaan titik dengan algoritma Welch-Powell.
