Judul: Analysis of Rice Supply Chain  Performance at PB Sumber Tani
Abstrak: Penelitian ini bertujuan untuk menguraikan kinerja rantai pasok di PB Sumber Tani. Metode yang digunakan adalah metodologi yang jelas subjektif dengan prosedur pengumpulan informasi melalui observasi, wawancara, dan kuesioner. Data dianalisis menggunakan metode Supply chain operations reference (SCOR) untuk mengevaluasi efisiensi dan efektivitas rantai pasok. Hasil perhitungan AHP cost menjadi prioritas utama dengan indikator biaya SCM. Hasil penelitian menunjukkan bahwa rantai pasok PB Sumber Tani memiliki beberapa kelemahan seperti ketergantungan pada cuaca, fluktuasi harga, dan kesulitan mendapatkan bahan baku berkualitas. Namun, dengan perbaikan manajemen rantai pasok, efisiensi dapat ditingkatkan yang berdampak positif pada kinerja keseluruhan. Temuan ini memberikan implikasi penting bagi pelaku usaha dan pemerintah dalam pengambilan kebijakan terkait manajemen rantai pasok beras., This study aims to analyze the performance of the rice supply chain at rice mills with a case study of PB Sumber Tani. The method used is a descriptive quantitative approach with data collection techniques including observation, interviews, and questionnaires. Data were analyzed using the Supply chain operations reference (SCOR) method to evaluate the efficiency and effectiveness of the supply chain. The results of the AHP calculation is cost become top priority with the indicator of SCM cost. The research indicate that the PB Sumber Tani supply chain has several weaknesses, such as dependence on weather conditions, price fluctuations, and difficulties in obtaining quality raw materials. However, with improvements in supply chain management, efficiency can be enhanced, leading to positive impacts on overall performance. These findings provide important implications for business practitioners and policyMakers in making decisions related to rice supply chain management.

Judul: Design for Performance Improvement and Value Addition in Rice Supply Chain at Modern Rice Milling Plant Perum BULOG Subang
Abstrak: Modern Rice Milling Plant (MRMP) Subang merupakan perusahaan penggilingan padi yang mulai beroperasi pada bulan Oktober tahun 2022 sehingga belum pernah melakukan identifikasi terhadap kondisi rantai pasoknya. Proyek desain utama ini bertujuan mengidentifikasi situasional, kinerja, dan nilai tambah rantai pasok beras, merumuskan strategi peningkatan kinerja dan nilai tambah rantai pasok beras dan merancang ulang model rantai pasok baru. Analisis situasional rantai pasok menggunakan pendekatan Food Supply Chain Management (FSCM). Analisis kinerja rantai pasok menggunakan metode Supply Chain Operations Reference Digital Standard (SCOR DS). Nilai kinerja rantai pasok pada MRMP Subang dan mitra penyalur berturut-turut adalah 76,85% dan 68,54%. Nilai tambah dianalisis menggunakan metode hayami dan didapatkan nilai tambah sebesar Rp843.000/ton Gabah Kering Panen (GKP) atau sebesar 12,41%. Kinerja dan nilai tambah rantai pasok beras dapat ditingkatkan menggunakan model Analytical Network Process (ANP).Strategi peningkatan kinerja dan nilai tambah terpilih adalah penerapan sistem perencanaan produksi dan penerapan sistem jaminan mutu yang dimasukkan pada rancangan model rantai pasok yang baru., Modern Rice Milling Plant (MRMP) Subang is a rice milling company that started operations in October 2022 and has never identified its supply chain conditions. This major design project aims to identify the rice supply chain's situational, performance, and added value, formulate strategies to improve the performance and added value of the rice supply chain, and redesign a new supply chain model. The situational analysis of the supply chain used the Food Supply Chain Management (FSCM) approach. Supply chain performance analysis using the Supply Chain Operations Reference Digital Standard (SCOR DS) method. The supply chain performance scores for Subang MRMP and supply partners were 76.85% and 68.54%, respectively. The added value was analyzed using the Hayami method and obtained an added value of IDR 843,000/ton of Harvested Dry Grain (GKP) or 12.41%. The performance and value-added of the rice supply chain can be improved using the Analytical Network Process (ANP) model. The selected performance improvement and value-added strategies are the implementation of a production planning system and a quality assurance system incorporated in the design of the new supply chain model.

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.
