Shallot is one of the kitchen spices that is often used by the community. Shallot contains several useful compounds and one of them is phytosterol. Along with the development of science and technology, phytosterol can be used to reduce blood cholesterol levels and prevent heart disease, so it is very beneficial for human health. In this study, phytosterol compounds were identified and isolated. The dried onion is then pureed and sifted to 100 mesh. The sieved powder is then extracted by reflux extraction method within 6 hours. The results of the extract were then isolated by column chromatography and identified by thin layer chromatography (TLC). The TLC test uses -sitosterol as a standard and anisaldehyde reagent as a stain appearance. The TLC plate which had stained appearance was then analyzed using the TLC Scanner method. The results of the TLC test showed that the extract of positive red onion was purple and contained fitosterol. The results of the TLC Scanner also show that the peak and spectrum of the samples are the same as the standard -sitosterol and positively contain fitosterol.

Poly(lactic acid) (PLA) is a promising candidate as a renewable resource for plastic production. The use of PLA as a plastic material helps alleviate issues associated with waste. In the production of Polylactic Acid (PLA), by-products such as water are generated, and the Lewis acid catalyst used in PLA production is susceptible to rapid decomposition and deactivation by water. This research aims to optimize PLA polymerization using a water-resistant catalyst, Al(DS)3, to achieve an optimum PLA molecular weight.The synthesized PLA is then analyzed using viscometry to determine its molecular weight. Optimization is carried out using the Response Surface Methodology (RSM) with a Central Composite Design (CCD) matrix. The molecular weight of the synthesized PLA is measured through viscometry, and the data is input into Minitab to obtain the optimum point. This optimum point is further validated by calculating the error value from the optimization results. The optimized PLA results in a molecular weight of 10.313 g/mol with an error value of 4.47% at a catalyst concentration of 0.15% and an operating temperature of 180 °C.

Lack of environmental cleanliness is one of the factors that can cause the growth of mosquito larvae. Therefore, educational efforts are needed about efforts to maintain environmental cleanliness as a solution to eradicate mosquito larvae. The purpose of this education is for students to know how to maintain environmental cleanliness and efforts to prevent the growth of mosquito larvae. This education is carried out through 4 stages, namely: 1) Introduction and Pretest 2) Material Explanation 3) Posttest and 4) Mutual Cooperation with the 3M movement (Draining, Covering, and Burying). The results of the education provided showed that 86,36% of students really understood the solution to eradicating mosquito larvae

Pegon script is one of the valuable legacies of the scholars who spread Islam in the archipelago, especially for Nahdlatul Ulama'. However, its existence has decreased until now except in the Salaf Islamic Boarding Schools. On the other hand, MI NU KH. Mukmin as a formal educational institution tries to help preserve Pegon script in schools. This study aims to describe the background, objectives, and elements of Pegon script learning, as well as its influence on formal educational institutions, especially MI NU KH. Mukmin. This study uses a phenomenological approach. Data collection techniques use in-depth interviews and literature studies. The results of the study show that Pegon script learning is one of the compulsory subjects at MI NU KH. Mukmin in a local content. There is also a Pegon script learning guidebook, learning evaluation, and supporting learning media like other subjects. In addition, after students have completed learning the Pegon script, learning continues with learning the Safinatun Najah book until grade 6. On the other hand, learning the Pegon script is to equip students, because most of the graduates of MI NU KH. Mukmin Sidoarjo continue their education to Islamic boarding schools. MI NU KH. Mukmin also received appreciation for the 1st Place PWNU East Java Award in 2023 through its superior programs, one of which is learning the Pegon script.

Biogas is a natural gas produced by anaerobic bacteria from processing organic matter and used in energy production. The use of biogas is a green technology that is beneficial to the environment. Biogas technology facilitates the use of animal and plant waste such as cow dung and water hyacinth plants. This study aims to optimize biogas production to achieve optimal biogas volume. Anaerobic Fermentation produces biogas for 21 days. Response Surface Methodology (RSM) with a Central Composite Design (CCD) matrix is used for this optimization. To find the ideal location, the biogas volume data is entered into Minitab. The error value from the optimization results is then computed to verify this optimum location. The optimized biogas produces a volume of 344 mL with an error value of 1.74% at a composition of 0.6089 kg of water hyacinth and 0.6860 kg of cow dung.

Berbagai keadaan operasi selama proses produksi di mana unit-unit proses sering kali saling memengaruhi atau berinteraksi satu sama lain. Variabel-variabel dalam setiap proses juga saling berinteraksi. Berdasarkan variabel masukan dan keluaran, sistem dapat dibagi menjadi dua kategori, yaitu Single Input Single Output (SISO) dan Multi Input Multi Output (MIMO). Secara umum, pengujian berbagai sistem kontrol untuk desain tiga tangki menggunakan sistem MIMO. Tujuan dari penelitian ini adalah melakukan simulasi loop terbuka pada sistem tiga tangki menggunakan perangkat lunak NI LabView. Tahapan penelitian yang dilakukan untuk menyelesaikan penelitian ini meliputi pembuatan model matematika dari sistem tiga tangki, kemudian menentukan spesifikasi proses tangki, selanjutnya melakukan simulasi loop terbuka, dan mengidentifikasi fungsi transfer menggunakan metode uji langkah (step test). Hasil yang diperoleh dari penelitian ini menunjukkan bahwa sistem tiga tangki dapat membentuk sistem MIMO 2x2 dengan dua variabel yang dikendalikan (h1 dan h3) serta dua variabel yang dimanipulasi (U1 dan U2). Fungsi transfer dapat diidentifikasi menggunakan metode uji langkah dengan pendekatan First Order Plus Time Delay (FOPTD).

Di era globalisasi, kewirausahaan menjadi kompetensi krusial bagi mahasiswa untuk berperan sebagai agen perubahan sosial dan ekonomi melalui pemanfaatan potensi lokal, salah satunya bunga telang (Clitoria ternatea). Bunga telang kaya akan antosianin dan memiliki khasiat antioksidan, pewarna alami, serta potensi anti diabetes. Kegiatan ini bertujuan menumbuhkan ide bisnis mahasiswa dengan memanfaatkan warna alami bunga telang sebagai dasar pengembangan produk wirausaha berbasis bahan alami. Metode yang digunakan adalah presentasi pembuatan olahan makanan berbasis bunga telang dan dilakukan pengetesan rasa dan visual warna. Hasilnya, ketiga produk inovasi tersebut berhasil dikembangkan dengan ciri khas warna biru keunguan alami yang menarik perhatian, dengan proses pembuatan yang relatif mudah diikuti. Pemanfaatan bunga telang terbukti efektif meningkatkan daya tarik visual produk sekaligus memberikan nilai tambah kesehatan. Disimpulkan bahwa pengembangan usaha berbasis bunga telang memiliki potensi besar sebagai ide bisnis mahasiswa yang kreatif, berkelanjutan, dan ramah Lingkungan.
