It is a common practice for Airline Industries have bargaining discountprices of tickets are sold to seat in cabin on the same flight. That callsRevenue Management. The yield management has focused mainly on theairline industries. Bathia, Parekh and Richter have developed some simpledecision rules to determine optimal booking limits in nested fare inventorysystem. To maximize the expected revenue, management needs todetermine the optimal times to switch between prices based on theremaining season and inventory.Keyword: Mathematical modeling, Nonlinear programming, InventoryControl

Gender is still an issue that is always linked to students’ ability, including their learning outcomes. This research aims to examine the correlation between gender and students’ biology learning outcomes. The research involved 15 male and 15 female students from classes X, XI, and XII Science at MA Ghozaliyah in the 2022/2023 academic year. Students’ biology learning outcomes were obtained from odd semester final exam scores. Data analysis was carried out statistically using the Eta correlation formula. The research results show that there is a weak negative linear relationship between gender and students’ biology learning outcomes, because the eta value obtained was 2,94 and Fcount < Ftable at a significance level of 0,01.

Oriensubulitermes inanis (Haviland) is one of the endemic termites in the Oriental Region and plays a very important role in the decomposition process in tropical forests. This study aims to redescribe O. inanis from Indonesia. Termite were collected by adopting a Standized Sampling Protocol (Jones & Eggketon 2000) and final taxonomic confirmation were conducted at the Natural History Museum UK) and Florida University (USA). We found 21 colonies of O. inanis from various habitats and altitudes in Indonesia. Distribution of O. inanis is often correlated with biodiversity status in tropical forests. Worker caste mandible provides the most useful character for the description of O. inanis. In Southeast Asia, this rare species is restricted and can be found only in the Malay Peninsula, Borneo and Sumatra, and absence from Java. Decayed wood, base of tree trunks, and other termite nests (epigeal mounds) are selected media used to construct their nests. Limited population number in a colony, restricted alates flying ability, and secretive nest habitats are thought to influence the distribution of O. inanis in Indonesia.

Latar Belakang: Hidroksiapatit merupakan salah satu material biokeramik dengan rumus kimia Ca10(PO4)6(OH)2 yang termasuk dalam senyawa kelompok mineral apatit yang terdiri dari kalsium dan fosfor. Sintesis hidroksiapatit dapat menggunakan bahan alami yaitu sisik ikan gabus (Channa striata). Tujuan: Tujuan penelitian ini untuk mengetahui perbedaan karakteristik hidroksiapatit dari sisik ikan gabus dengan variasi suhu kalsinasi. Metode: Penelitian ini mensintesis sisik ikan gabus dengan menggunakan prekrusor kalsium hidroksida (Ca(OH)2) dan asam fosfat (H3PO4) serta penambahan larutan NaOH. Endapan hidroksiapatit sisik ikan gabus yang dihasilkan lalu dikalsinasi menggunakan berbagai variasi suhu yaitu 700⸰C, 800⸰C, dan 900⸰C. Karakterisasi struktur derajat kristalinitas hidroksiapatit ditentukan dengan menggunakan x-ray diffraction (XRD) Hasil: Analisa XRD menunjukkan derajat kristalinitas hidroksiapatit sisik ikan gabus pada suhu suhu 700⸰C dengan tingkat derajat kristalinitas 67.7%, 800⸰C dengan tingkat derajat kristalinitas 79.2%, dan pada suhu 900⸰C dengan tingkat derajat kristalinitas 58.5% Kesimpulan: Suhu 800⸰C merupakan suhu optimum dalam sintesis sisik ikan gabus dikarenakan memiliki derajat kristalinitas yang paling tinggi. Kata Kunci: Sisik ikan gabus, derajat kristalinitas, hidroksiapatit, suhu kalsinasi, x-ray diffraction

Operations research is widely applied by industrial and business companies to maximize profits or minimize potential losses. In practice, many operations research problems cannot be solved using linear models and require nonlinear models instead. This is the case for Lavera Konveksi, a company that produces long-sleeve t-shirts, collared t-shirts, plain t-shirts, and training pants each month. The company faces issues with fluctuating production quantities and costs. This research aims to develop a nonlinear objective function model to minimize production costs and determine the minimum production cost and the optimal number of items to be produced by Lavera Konveksi. The data used in this study includes production quantities and costs for the period from December 2019 to April 2020. The research employs the Quadratic Programming method, where the nonlinear problem is transformed into a linear case and then solved using the Wolfe Simplex Method. The results indicate that Lavera Konveksi should produce 530 long-sleeve t-shirts, 455 collared t-shirts, 425 plain t-shirts, and 180 training pants to achieve a minimum production cost of IDR 49,436,799.

Motor vehicle distribution companies which are the source of this research data are located in Banda Aceh and Medan. The vehicles will then be sent to several areas, namely Lhokseumawe, Panton Labu, Meulaboh, Takengon, Subulussalam, Kuta Binjei, Kutacane, Aceh Singkil, Rimo and North Aceh. The problem in the process of sending vehicles is that if the inventory of vehicles in one of the warehouses is empty, then the supply of vehicles is obtained from warehouses that are still available in the warehouse regardless of distance. This paper describes the optimization of transportation costs for Fleet product distribution. Products are distributed from two sources to ten destinations. The cost of sending the vehicle incurred by the company is Rp 152,994,625. By using the Vogel's Approximation Method (VAM) and Modified Distribution Method (MODI), the total cost generated is Rp 142.728.100. Solving transportation problems with the transportation method can minimize and optimize the cost of sending a vehicle of Rp 10.266.525 or 6.71% and it can increase company profits.
