Waste is the result of disposal from a production process, both from industry (factories) and domestic (households). One waste that is often encountered is orange peel, which is included in the organic waste category. Oranges are generally utilized as an ingredient in various food products, while the peel is often thrown away. Orange peels contain important nutrients that can be utilized in mak…
Lichen is a form of symbiosis between fungi and algae that is very widespread and can live on substrates that lack nutrients. Lichen has a high level of sensitivity to changes in environmental conditions such as changes in temperature, humidity, light intensity, and air quality that can affect its species diversity. Pekanbaru City, which experiences an increase in the number of motorized vehicl…
Many people pay little attention to their health and have poor daily habits that can lead to an imbalance of microorganisms in the digestive system. One way to maintain the balance of these microorganisms is by consuming probiotics. One well-known probiotic food is fermented dairy products using lactic acid bacteria, such as yogurt. Yogurt is a product of milk fermentation involving two types o…
Nanas (Ananas comosus (L.) Merr.) merupakan buah tropis yang banyak dihasilkan di Indonesia, termasuk di Provinsi Riau, khususnya Kabupaten Kampar yang dikenal sebagai daerah penghasil nanas. Dengan produksi nasional mencapai 3,2 juta ton pada 2022, potensi pengembangan olahan nanas sangat besar, namun pemanfaatannya sebagai minuman fungsional seperti water kefir masih terbatas. Water kefir mer…
e-Booklet adalah bentuk media pembelajaran elektronik yang disusun secara sistematis ke dalam satuan-satuan pembelajaran kecil dengan tujuan untuk menyampaikan informasi atau materi pelajaran secara lebih efektif dan menarik. Tidak seperti buku cetak atau booklet konvensional, e-Booklet memiliki keunggulan dalam hal penyajian visual. Media ini dapat memuat elemen-elemen seperti teks, gambar, fo…
This research is a development research (R&D) with the aim of producing a Problem Based Learning (PBL) based teaching module on the topic of social arithmetic to facilitate mathematical problem solving skills (KPMM) of phase D students that have met the valid and practical requirements. This development research uses a 4D development model with development stages, namely defining, designin…
Essentially, every worker will eventually reach a point where they have com- pleted their period of employment, but economic needs and protection are still required to ensure their well-being in the future. Therefore, one way to ensure future well-being is for each worker to participate in a program that can fulfill their needs during old age, namely the old-age benefit program, commonly kno- w…
Makeham’s law considers two mortality rates, namely a constant mortality rate representing deaths due to factors unrelated to age, such as accidents or conge- nital diseases, and a mortality rate that increases with age due to senescence. This renders Makeham’s law to provide a precise calculation of mortality proba- bilities, thereby a more accurate calculation of premium reserves and miti…
Life risks such as accidents, illness, and death can happen to anyone and anywhere. So one way to reduce the possibility of this happening is to take out insurance, especially dual-purpose life insurance that provides protection both when the insured lives until the end of the coverage period or dies in the insurance period. This final project discusses the calculation of premium rese- rves for…
This final project discusses the modular total vertex and edge irregularity stre- ngth of the generalized Petersen graph (GPn,2). The modular total vertex and edge irregularity strength of a graph G, denoted by mtvs(G) and mtes(G), is the minimum value of k such that the graph G has a modular total vertex and edge irregular k-labeling. A total k-labeling is called a modular total vertex irregul…
ABSTRACT ANDI RIO RAMADHAN. 2110246916, Construction and Analysis of Filters in BN-Algebra, supervised by Sri Gemawati and Kartini. BN-algebra (A; ∗, 0) is a non-empty set A equipped with a binary operation ∗ and a constant 0, which satisfies the following axioms: (B1) a ∗ a = 0, (B2) a ∗ 0 = a, and (BN) (a ∗ b) ∗ c = (0 ∗ c) ∗ (b ∗ a) for every a, b, c ∈ A. A subset I …
