The mortality table is statistical data from a population that states the probability that someone will die. With the modeling of the mortality table, the probability of someone dying can be known. The mortality table can be estimated by a method, one of which is the Cubic spline Interpolation method to estimate the probability of death for Indonesian people in general. The approximate value of the probability of death for a person at a certain age is obtained from the Cubic spline interpolation followed by the Spline smoothing process. Cubic interpolation is used to estimate the probability value between the values of a person's age at death. The Cubic spline interpolation solution uses a system of linear equations because the cubic function runs from  to 1, in this case according to the 2011 mortality table,  moves from 0 years old to 111 years old. The solution to a system of linear equations using Gaussian elimination produces a tridiagonal matrix to find out the points as unknown coefficients. The estimated value using the Cubic spline Interpolation method was tested using the MAPE method to determine the accuracy of the approximation value. \u0000Abstrak.

One of the economic conditions in society is poverty. Poverty is the inability of a person to meet his basic needs, namely clothing, food and shelter. Therefore, the government's role is needed to help people who are lacking so they can live their lives. The only assistance provided by the government is the Assistance Fund for the underprivileged. In practice, the distribution of aid funds in the community is not always on target. This also happened in one of the villages, namely Sindang village. The aim of the research is to assist in the selection stage of receiving aid funds with the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. The TOPSIS method is one of the methods in a decision support system. The use of the TOPSIS method is to obtain more objective and precise results. The calculation of the TOPSIS method at the stage of selecting grant recipients was carried out using Microsoft Excel software. The results obtained are in the form of a list of recipients of aid funds based on preference values. The order is based on the highest preference value. The top sequence is people who are entitled to receive aid funds, while those at the bottom do not or are less eligible to receive aid funds. \u0000Abstrak. Salah satu kondisi perekonomian di masyarakat adalah kemiskinan. Kemiskinan merupakan ketidakmampuan seseorang dalam memenuhi kebutuhan dasarnya, yaitu sandang, pangan, dan papan. Oleh karena itu, dibutuhkan peran pemerintah untuk membantu warga yang kekurangan agar dapat melangsungkan kehidupannya. Bantuan yang diberikan pemerintah salah-satunya adalah Dana Bantuan untuk masyarakat yang kurang mampu. Pada praktiknya penyaluran dana bantuan di masyarakat tidak selalu tepatan sasaran. Hal tersebut juga terjadi di salah satu desa, yaitu desa Sindang. Tujuan penelitian ialah membantu tahapan seleksi penerimaan dana bantuan dengan metode Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). Metode TOPSIS merupakan salah satu metode dalam sistem pendukung keputusan. Digunakannya metode TOPSIS ialah untuk mendapatkan hasil yang lebih objektif dan tepat.

Investors in investing will be faced with uncertainty. If an investor takes a risk, then he will also expect a return that is proportional to the risk he will take too. Efforts to reduce the risk that will be faced by investors is by diversifying to create a portfolio. Investors in investing expect high returns with small risks from the portfolio they form. Investors must find a way to get a return that is not far from the Expected Return with a small risk. Models that can be used to calculate the Expected Return include the Capital Asset Pricing Model (CAPM) and the Arbitrage Pricing Theory (APT). The CAPM model and the APT model have differences, namely in the CAPM model the risk factor considered is systematic market risk while the APT model includes several macroeconomic factor variables.

Many people were not aware that mathematics is often used to solve problems in their daily life. It can solve various problem which may connected to one's hobby, such as  music. Many did not realize that music is related to mathematics. One of the music theory that is closely related to mathematics is the use of numerical notation. One of the important aspect of music theory is chords, which is a group if notes that produce harmonious sound when played simultaneously. There are many variations of chords, especially in blues songs. To determine the composition of the chord itself, the major scale of the chord was used, and the scales of the 12 existing notes transformed into integer using Integer Model of Pitch. In this research, the modulo transposition function was used to find a scale with 12 different basic tones. Modulo arithmetic was also used in this study to transpose several notes in chord compositions. The scales that have been transposed then was used to translate chord compositions in blues songs. \u0000Abstrak.Pada kehidupan sehari – hari banyak yang tidak sadar bahwa ilmu matematika sering digunakan untuk menyelesaikan masalah.

Selain notasi angka adapun akor yang merupakan dari nada – nada yang apabila dimainkan secara bersamaan akan menghasilkan suara yang harmonis. Akor sendiri memiliki banyak variasi sehingga komposisi di dalam akor bisa dikatakan sangat bervariasi terutama dalam lagu beraliran blues. Musik beraliran blues menggunakan akor yang bervariasi dalam satu lagunya. Untuk menentukan komposisi akor sendiri digunakan tangga nada mayor dari nama akor tersbut sehingga harus dicari semua tangga nada dari 12 nada yang ada. Dalam penelitian ini fungsi transposisi modulo digunakan untuk mencari tangga nada dengan 12 nada dasar yang berbeda dengan menggunkan Integer Model of pitch. Aritmetika modulo pun digunakan dalam penelitian ini untuk mentrasposisi beberapa nada yang ada komposisi akor. Tangga nada sudah ditransposisi selanjutnya digunakan untuk menerjemahkan komposisi akor dalam lagu blues yang akan dijadikan sebagai objek penelitian.","PeriodicalId":31272,"journal":{"name":"Jurnal Riset Pendidikan Matematika","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78257799","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}

The entire population was divided into six compartments, mask wearing and non mask wearing susceptible compartments, exposed compartment, mask wearing and non mask wearing infected compartments, and recovered compartment. The model for the spread of Covid-19 was formed by compiling a compartment diagram for the spread of Covid-19 disease with the parameters of mask wearing and vaccination first. Then, disease-free equilibrium point, endemic equilibrium point, and Basic Reproduction Number are determined. After that, numerical simulation was carried out. The results of this study indicate that the disease-free equilibrium point is locally asymptotically stable when the Basic Reproduction Number is less than one.
