PRARANCANGAN PABRIK ASAM FENIL ASETAT DARI BENZIL SIANIDA DAN ASAM SULFAT DENGAN PROSES HIDROLISIS KAPASITAS 4.500 TON/TAHUN

Asam fenil asetat adalah salah satu senyawa organik yang utamanya digunakan sebagai bahan baku pembuatan obat-obatan farmasi atau bahan campuran untuk pembuatan produk kimia atau farmasi lain. Asam fenil asetat sering digunakan sebagai bahan pembuatan phenylaceton dan penicillin yang diperlukan untuk produksi amphetamine. Asam fenil asetat juga sering dipakai untuk bahan campuran dalam industri parfum, misal methyl phenylacetic madu dan beraroma mawar, ethyl phenylacetic acid beraroma madu, amylphenylacetic acid beraroma coklat. Pembuatan asam fenil asetat dapat dilakukan dengan beberapa proses, salah satunya adalah dengan proses hidrolisis benzil sianida dan asam sulfat.    Pembuatan asam fenil asetat dengan proses hidrolisis diawali dengan mempersiapkan bahan baku yaitu mengencerkan asam sulfat dengan air memanaskannya  sebelum dimasukkan ke dalam reaktor dengan tekanan operasi 1 atm dan suhu 90°C. Proses hidrolisis terjadi di dalam reaktor, kemudian hasil keluaran reaktor diteruskan ke rdvf untuk memisahkan filtrat dan cake yang terbentuk. Filrat yang dihasilkan akan dimasukkan ke dekanter untuk memisahkan komponen berdasarkan massa jenisnya, sedangkan cake berupa amonium bisulfat dialirkan menuju gudang penyimpanan menggunakan cooling conveyor. Hasil pada atas dekanter akan diteruskan ke menara distilasi untuk memisahkan asam fenil asetat dari reaktan yang tersisa, sedangkan hasil pada bawah dekanter akan di-recycle kembali ke dalam reaktor. Hasil atas menara distilasi didinginkan terlebih dahulu di  heat exchanger lalu di-recycle kembali ke reaktor. Hasil bawah menara distilasi didinginkan di heat exchanger menjadi 100oC, kemudian diumpankan ke prilling tower untuk dikristalkan. Kemudian padatan kristal yang keluar dari prilling tower di perkecil ukurannya di ball mill dan dilakukan pengayakan pada screening untuk mendapatkan produk yang seragam.

Unconfined Compressive Strength Of Sedimentary Soil Stabilized With Portland Cement With Varying Curing Time

Soil improvement is commonly carried out in construction work with the aim of increasing the bearing capacity / strength of the soil so that it can carry the construction load that will stand on it. The method that is often used is soil stabilization with the addition of stabilization materials. In this study, soil stabilization was carried out with the addition of Portland Cement. This research begins with soil sampling and laboratory testing to determine the physical and mechanical properties of the soil, followed by making soil samples for Unconfined compressive strength testing with 3 variations of cement, namely 5%, 10%, and 20%. From the results of this study, it is known that the soil sample has a moisture content of 97.13%, specific gravity of 2.51, liquid limit of 33.80% and plasticity limit of 22.52% with plastic index value = 11.28%. Based on the soil classification system with the USCS (Unified Soil Classification System) method, sedimentary soil types include CL (Clay-Low) soil types, clays with low plasticity values. Unconfined compressive strength testing on sedimentary soil samples without portland cement obtained a compressive strength value of 0.352 kg/cm2. And the soil stabilized with various variations of Portland Cement obtained the highest compressive strength value of 14.45 kg/cm2, namely in the soil sample + 20% cement with 28 days curing time. The results showed that the value of Unconfined compressive strength for sedimentary soil dredging dam bili-bili stabilized with Portland cement tends to increase its bearing capacity / strength with the addition of the percentage of Portland cement and curing time, with this value the category of hard soil consistency obtained can be used for building structures and road base soils

Evolusi Perundang-Undangan di Era Konstitusi Hukum: Tantangan dan Peluang

The life of the legal constitution has undergone significant developments since the past to the current modern era. The legal constitution era marked a paradigm shift from absolute authority to government based on the rule of law and recognition of human rights. These changes have influenced the formation and interpretation of legislation governing the social, political and economic order in various countries. This article examines the evolution of legislation in the legal constitutional era by highlighting the challenges and opportunities faced. The main challenges stem from the complexity of the problems faced by modern society, including globalization, technology, environment and social dynamics. Rapid social change often requires a comparable legislative response to maintain justice and balance in society. In addition to challenges, the era of legal constitutions also brings opportunities for more inclusive and progressive legal innovations. By giving power to constitutional institutions such as the Constitutional Court, legislation can accommodate the aspirations and needs of diverse communities. Increasing public participation in the legislative process is also one of the great potentials for creating more representative and responsive laws. This study uses a descriptive analysis method by reviewing the latest literature on changes to the legal constitution and their impact on legislation. The main findings show that the evolution of legislation in the era of legal constitutions provides complex consequences and challenges, but at the same time presents opportunities to create a legal system that is more just and relevant to the time
