Abstract

Jalan pada umumnya menggunakan perkerasan lentur yaitu aspal. Aspal digunakan sebagai perekat antar agregatnya. Kebutuhan aspal di kota-kota besar di Indonesia semakin lama semakin meningkat, untuk pembuatan jalan baru maupun perbaikan jalan. Konstruksi menggunakan aspal panas menyebabkan polusi udara sehingga dilakukan penelitian pengganti aspal panas tersebut agar mengurangi polusi dengan aspal dingin yaitu aspal emulsi. Penelitian ini bertujuan untuk mengetahui pengaruh nilai sifat-sifatmarshall dari aspal emulsi tipe CSS-1h, CMS-1, dan CRS-1 serta membandingkan stabilitasnya dengan laston. Penelitian ini menggunakan kadar aspal emulsi 7%, 7,5%, 8%, 8,5%, 9% dan aspal laston dengan kadar 5%, 5,5%, 6%, 6,5%, 7% sesuai dengan ketentuan Binamarga. Hasil penelitian menunjukan bahwa aspal emulsi CSS-1h dapat dipakai sebagai perkerasan jalan. KARO aspal emulsi CSS-1h adalah 7% dengan nilai stabilitas 1259 kg lebih tinggi dibanding laston dengan KAO 6% dengan stabilitas 1033,35kg. Penggunaan aspal emulsi bisa diterapkan untuk perkerasan dengan tujuan Go Green.

Abstract

The purpose of this research was to study the effect of drying time on the mechanical properties of natural rubber latex filled with cassava peel waste modified alkanolamide. Cassava peel is a waste, containing cellulose which is potential as fillers in natural rubber latex products. Cassava peel waste was dried and milled until the size of 100 mesh. Alkanolamide is one type of non-ionic surfactant which is synthesized from RBDPS (Refined Bleached Deodorized Palm Stearin) and diethanolamine. Alkanolamide has polar group which can modified cassava peel waste and make strong chemical bonding with natural rubber latex. The production of natural rubber latex products was started from pre-vulcanization at 70°C until the system was cured and the chloroform number has reached number 3. Natural rubber latex was formed into films by coagulant dipping and drying method at 120°C for 10 minutes and 20 minutes. Results show that longer drying time will improve the crosslink density and tensile strength of natural rubber latex products until the addition of 15 phr cassava peel waste powder. Keywords: drying time, alkanolamide, cassava peel, natural rubber latex.ABSTRAKPenelitian ini bertujuan untuk mempelajari pengaruh waktu vulkanisasi terhadap sifat mekanik produk lateks karet alam berpengisi kulit singkong termodifikasi alkanolamida. Kulit singkong merupakan limbah yang mengandung selulosa dan berpotensi untuk digunakan sebagai bahan pengisi dalam produk lateks karet alam. Kulit singkong dikeringkan dan dihaluskan hingga berukuran 100 mesh. Alkanolamida merupakan surfaktan non-ionik yang disintesis dari bahan baku RBDPS (Refined Bleached Deodorized Palm Stearin) dan dietanolamina. Alkanolamida mengandung gugus polar yang dapat memodifikasi tepung kulit singkong dan membentuk ikatan kimia yang kuat dengan lateks karet alam. Proses pembuatan produk lateks karet alam dimulai dengan proses pra-vulkanisasi pada suhu 70°C hingga lateks karet alam telah matang dan bilangan kloroform telah mencapai angka 3. Lateks karet alam dicetak dengan menggunakan teknik pencelupan berkoagulan dengan metode pengeringan pada suhu 120°C selama 10 menit dan 20 menit. Hasil penelitian menunjukkan waktu vulkanisasi yang lebih lama dapat meningkatkan nilai densitas sambung silang dan kekuatan tarik produk lateks karet alam hingga penambahan 15 phr tepung kulit singkong.     Kata kunci: waktu vulkanisasi, alkanolamida, kulit singkong, lateks karet alam.

Abstract

Proses grinding material halus dari HRC Product Bin secara berurutan melewati Air Slide, kemudian Ball Mill, lalu masuk ke Separator. Setelah itu material mengalami proses separasi (pemisahan antara material yang memiliki kehalusan sesuai target dengan material kasar), material hasil penggilingan HRC (HRC Product) memiliki nilai kehalusan yang cukup untuk langsung dijadikan produk semen, sehingga bila material yang sudah halus masuk ke Ball Mill menyebabkan terjadinya proses penggilingan ulang yang merugikan (kapasitas produksi bisa lebih banyak dengan penggunaan daya yang sama). Perancangan sistem transportasi bypass Air Slide dari HRC Product Bin ke Separator dibutuhkan sebagai solusi mencegah terjadinya penggilingan ulang, sehingga material yang memiliki kehalusan cukup, langsung diseparasi menjadi produk semen.

Abstract

Major Depressive Disorder (MDD) is a chronic disorder characterized by at least a two-week-long major depressive episode. Selective Serotonin Reuptake Inhibitors (SSRIs) remain the primary prescribed antidepressants to treat MDD. However, SSRIs themselves are found to be ineffective in some individuals or may even lead to adverse side effects. These variable responses have been linked to the drug being metabolized by CYP2C19, which exhibited various polymorphisms. Understanding how gene polymorphism affects drug metabolism is essential since these insights can revolutionize clinical practice, allowing for more precise and personalized treatment approaches that optimize efficacy while minimizing side effects. This issue is particularly pertinent in Indonesia, where research in this area lags behind the pressing need for such studies. In this review, the impact of CYP2C19 polymorphism on the effectiveness of SSRI class drugs, namely citalopram, escitalopram, and sertraline, are explored. Nine relevant articles related to the topic have been studied in Japan, China, Turkey, Russia, Scandinavia, and Australia. The results concluded that CYP2C19 polymorphism can influence the metabolism of SSRIs (citalopram, escitalopram, and sertraline) due to its variability in enzyme activities, which includes both loss-of-function (*2, *3) and gain-of-function (*17) polymorphisms. Consequently, these genetic variations can lead to significant changes in drug efficacy and safety changes within individual patients. This review sheds light on the importance of considering genetic factors when prescribing SSRIs for MDD in the future treatment strategies.

Abstract

This study explains the benefits obtained from the integration of Design for Assembly (DFA) and Value Engineering (VE) methods in the product design process. DFA is proven to provide benefits such as product simplification, reduced assembly costs, and improved quality by creating product structures that are simpler and easier to install. While VE adds value by taking into account the replacement of expensive or difficult-to-assemble components, speeding up overall assembly time. Although specific research on the integration of these two methods may be limited, studies show that the combination of DFA and VE produces design alternatives that consider various aspects of the product life cycle. The result is reduced costs, faster development times, and a reduced need for rework. The concepts and benefits of integrative DFA and VE approach can be an effective strategy for enhancing assembly efficiency and reducing production costs in product design.

Abstract

This research explores the optimization of mango yogurt production, leveraging mango as the primary fermentation ingredient and Lacticaseibacillus paracasei strain Shirota (LcS) as the probiotic inoculum. Traditional yogurt, typically derived from animal milk, faces competition from plant-based alternatives. The research objective is to investigate the impact of inoculum ratios and sucrose concentrations on LcS density and sensory attributes, with a focus on the Substrate to Inoculum Ratio (S/I) as a critical parameter influencing microbial metabolism and population dynamics. Various inoculum ratios (1:1, 1:2, 1:4, 1:8 v/v) and sucrose concentrations (0%, 2.5%, 5%, 7.5%) were applied in mango yogurt production. Results from ANOVA analysis indicated significant differences in LcS density among inoculum ratios (F3,16 = 37.01, P = 0.000) and sucrose concentrations (F3,16 = 19.07, P = 0.000). The 1:2 inoculum ratio and 7.5% sucrose concentration emerged as optimal, as evidenced by stable pH conditions and lactic acid profiles within recommended standards. Sensory analysis, employing a 5-point hedonic scale for color, odor, taste, and texture evaluation, revealed moderate acceptance. In conclusion, this study introduces an innovative approach to mango yogurt production, highlighting the potential of specific inoculum ratios and sucrose concentrations for optimal results. The findings contribute to the broader landscape of plant-based yogurt alternatives, underscoring the need for ongoing refinement to meet commercial standards and ensure consumer satisfaction.
