Abstract

The increasing demand for pesticides in agriculture has led to a rise in the production of methyl isocyanate, a key intermediate in carbamate pesticide manufacturing. However, this process generates sodium sulfate as a by-product, dissolved in an aromatic solvent, which, if not adequately managed, contributes to environmental pollution and resource inefficiency. Chemical and environmental engineering are crucial in addressing this issue by developing effective separation and recovery methods. One potential solution is the distillation process, which separates sodium sulfate based on boiling point differences with water. However, the effectiveness of this method depends on operational conditions, particularly pressure and sulfuric acid concentration. This research focuses on optimising the recovery of sodium sulfate from methyl isocyanate production waste by investigating different operating pressures (atmospheric, vacuum, and combined) and sulfuric acid concentrations (0 M, 0.07 M, 0.15 M, 0.22 M, and 0.30 M). A recovery efficiency of sodium sulfate as high as 92.5% using vacuum distillation at a 0.22 M sulfuric acid concentration. Additionally, the condensate water contained 98.7% purity, making it suitable as a precursor for struvite fertiliser. Sodium sulfate is used as a raw material in producing insecticidal pesticides, with a purity level of 97.3%. This study demonstrates that an optimised distillation process can enhance the efficiency of pesticide production by minimising waste and maximising resource utilisation, contributing to cost efficiency and environmental in industrial pesticides.

Abstract

Islamic boarding school-based economic development leverages these schools to drive an independent economy through business units. This research aims to assess economic growth in West Javas Islamic boarding schools using qualitative descriptive methods, which outline factual situations and problems. The study found several Islamic boarding schools in West Java operate business units, including cooperatives, building rentals, and Santri Marts. However, economic development is slow due to limited business expertise among staff and the reliance on profit-sharing for business management, reducing the need for extensive control. Historically, Islamic boarding schools have focused primarily on education and religion, but since the 1970s, some have started to address social issues, including economic and political challenges. With 4,328 Islamic boarding schools and over 5 million students in West Java, there is significant economic potential. To harness this, the West Java Islamic Boarding School Cooperative Center (Kopontren) and the West Java Regional Office of the Ministry of Religion (Kemenag) organize business internships for 204 students. Empowering these schools through economic development can create greater independence and effectively leverage the vast student population.

Abstract

Penelitian ini bertujuan untuk mengetahui penerapan Strategi Bisnis Serta Dampak Pandemi COVID-19 pada PT. BPR Mitra Kopjaya Mandiri. Objek penelitian ini adalah Divisi Bisnis dan Operasional. Penelitian ini dilakukan dengan metode penelitian kualitatif studi kasus. Teknik Pengumpulan data dalam penelitian ini menggunakan wawancara dan dokumen. Pemilihan narasumber dipilih sesuai dengan kriteria tertentu. Hasil penelitian ini menunjukan bahwa pandemi COVID-19 memberikan dampak yaitu liquiditas sedikit terganggu, penurunan aset, adanya risiko kesehatan dan keselamatan karyawan serta nasabah, nasabah atau calon nasabah menolak ditemui, sulit berinteraksi dengan nasabah atau calon nasabah, angsuran bermasalah, penurunan minat pada beberapa produk, risiko pembiayaan meningkat, minat menabung dan deposito turun, dan nasabah banyak yang mengambil dananya. Untuk menanggulangi dampak pandemi COVID-19 PT. BPR Mitra Kopjaya Mandiri melakukan strategi khusus diantaranya penerapan protokol kesehatan, relaksasi angsuran, restrukturisasi angsuran, fokus pada segmen yang memiliki pendapatan stabil, memperluas jaringan, pengendalian biaya, melihat profil risiko nasabah, dan penundaan pembiayaan. Penerapan strategi bisnis memiliki pengaruh dalam menanggulangi dampak pandemi COVID-19 dan merupakan cara untuk mencapai tujuan bisnis. Dalam mencapai tujuan bisnis PT. BPR Mitra Kopjaya Mandiri melakukan strategi pemasaran, pembiayaan, penghimpunan dana, pengawasan, pengembangan SDM, dan operasional. Dalam penerapan strategi bisnis masih terdapat kendala yang dihadapi di antaranya semangat karyawan tidak stabil, divisi SDM belum tertata rapi, banyak syarat untuk pengajuan pembiayaan, hanya ada dua personel pengawasan, dan masih ada SOP yang belum sesuai.
