Judul: Analysis and Mitigation of Durian Monthong Supply Chain Risks in Palu at XYZ Co
Abstrak: Durian monthong merupakan buah musiman yang memiliki karakteristik dagingnya yang tebal, berwarna kuning terang, sangat manis, tekstur nya halus dan aromanya tajam. Salah satu penghasil durian monthong terbesar di Indonesia adalah Kota Palu, Sulawesi Tengah. Rantai pasok suatu perusahaan harus optimal karena memiliki peran penting dalam kesuksesan suatu perusahaan yang ditandai dengan beberapa karakteristik utama seperti responsif terhadap permintaan, biaya rendah, kolaborasi yang baik antar aktor rantai pasok, dan manajemen risiko yang efektif. Analisis ini dilakukan untuk mengetahui risiko yang terjadi atau memungkinkan terjadi sehingga perusahaan dapat melakukan aksi mitigasi dalam rangka mengurangi risiko tersebut. Penelitian ini dilakukan dengan menganalisis kondisi situasional rantai pasok menggunakan pendekatan Food Supply Chain Management (FSCM), mengidentifikasi kejadian risiko dan sumber risiko serta menentukan aksi mitigasinya menggunakan metode House of Risk (HOR) pada tiga titik yaitu supplier, packing house, dan distributor. Dari analisis tersebut didapatkan pada titik supplier, packing house, dan distributor memiliki sebanyak 7, 8, 7 prioritas sumber risiko dan 8, 8, 9 prioritas mitigasi risiko. Dengan teridentifikasinya prioritas sumber risiko diharapkan mampu membantu perusahaan sebagai salah satu alat penunjang keputusan untuk melakukan mitigasi risiko sesuai yang disarankan., Monthong durian is a seasonal fruit that is characterized by thick flesh, bright yellow color, very sweet, smooth texture and strong aroma. One of the largest producers of Monthong durian in Indonesia is Palu City, Central Sulawesi The supply chain of a company must be optimized, as it plays a crucial role in the success of a business, marked by several key characteristics such as responsiveness to demand, low costs, good collaboration among supply chain actors, and effective risk management. This analysis aims to identify current or potential risks so that companies can take mitigation actions to reduce these risks. This research was carried out by analyzing the situational conditions of the supply chain using the Food Supply Chain Management (FSCM) approach, identifying risk events and sources of risk and determining mitigation actions using the House of Risk (HOR) method at three points, namely suppliers, packing houses and distributors. The analysis results indicate that at the supplier, packing house, and distributor, there are 7, 8, and 7 priority risk sources and 8, 8, and 9 priority risk mitigations. By identifying priority sources of risk, it is anticipated that this will assist companies by serving as a decision support tool for implementing recommended risk mitigation strategies.

Judul: Inventory Management Analysis of Durian Monthong Palu at XYZ Co.
Abstrak: PT XYZ merupakan perusahaan distributor buah impor dan lokal salah satunya durian monthong palu. Sistem pengiriman durian menggunakan pendekatan push, dimana pengiriman dilakukan saat stok cukup untuk mengisi satu kontainer, ditambah ketidakpastian dalam jadwal dan jumlah pengiriman dari Palu. Diperlukan identifikasi dalam mengatasi masalah manajemen persediaan dan analisis yang akan membantu dalam mengembangkan strategi untuk mengelola persediaan durian monthong palu. Dalam penelitian ini menggunakan model economic order quantity (EOQ) dan perhitungan safety stock untuk menentukan jumlah pemesanan dan cadangan optimal. Menggunakan data historis yang kemudian dianalisis untuk mendapatkan pemahaman yang mendalam tentang pola permintaan dan variabilitasnya. Hasil penelitian menunjukkan bahwa idealnya perusahaan melakukan pemesanan sebanyak satu kontainer dalam sekali pemesanan atau pengiriman dengan frekuensi delapan kali pengiriman dalam setahun dan PT XYZ perlu mempersiapkan safety stock atau stok pengaman sebesar 12.262 unit. Dengan implementasi strategi yang tepat perusahaan dapat mengelola persediaan lebih baik dan mengurangi biaya operasioanl secara kesuluruhan., XYZ Co. is a distributor of imported and local fruits, including durian monthong palu. The durian delivery system uses a push approach, where shipments are made when there is enough stock to fill one container. Given the uncertainty in the schedule and quantity of shipments from Palu, it is necessary to identify and address inventory management issues and develop strategies to manage durian monthong inventory effectively. This research uses the economic order quantity (EOQ) model and safety stock calculations to determine the optimal order quantity and reserve levels. Historical data is analyzed to gain a deep understanding of demand patterns and variability. The results indicate that the ideal order quantity is one container per shipment, with a frequency of eight shipments per year. XYZ Co. also needs to prepare a safety stock of 12.262 units. By implementing the right strategies, the company can manage its inventory more effectively and reduce overall operational costs.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
