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: Analysis of the performance of the supply chain for cow's milk using the Supply Chain Operations Reference (Case Study at the Dairy Farm Cooperative in North Bandung)
Abstrak: Koperasi Peternakan Sapi Bandung Utara (KPSBU) merupakan salah satu koperasi yang menjual susu sapi perah. Koperasi tersebut perlu meningkatkan kinerja rantai pasok untuk meraih keunggulan bersaing. Tujuan penelitian adalah: (1) Menjelaskan rantai pasok susu sapi di KPSBU, (2) Membuat metriks pengukuran kinerja rantai pasok susu sapi di KPSBU berdasarkan pendekatan Supply Chain Operations Reference (SCOR), dan (3) Mengukur tingkat kepentingan (bobot) dari metriks kinerja rantai pasok susu sapi dengan Analytical Hierarchy Process (AHP). Metode kajian ini ialah analisis statistika deskriptif, perbandingan berpasangan, dan AHP. Metriks pengukuran kinerja rantai pasok susu sapi digunakan atas maksud menentukan bobot metriks kinerja rantai pasok, metriks yang diukur meliputi proses bisnis, parameter kinerja, atribut kerja, dan metriks pengukuran kinerja. Hasil identifikasi prioritas akhir tertinggi dengan menggunakan AHP adalah faktor terpenting pada proses bisnis yaitu source (pengadaan) dengan bobot sebesar 0.51007. Kualitas berperan terpenting bagi parameter kinerja dengan bobot 0.51391. Pada atribut kinerja, reliabilitas yaitu kepercayaan konsumen pada manajemen rantai pasok KPSBU menjadi faktor krusial berbobot 0.23654. Matriks pengukuran kinerja faktor yang paling penting yaitu kinerja pengiriman dengan bobot 0.15297, yang merupakan tujuan utama dari AHP., North Bandung Cattle Farm Cooperative (KPSBU) is a cooperative that sells dairy cow milk. The cooperative needs to improve supply chain performance to gain competitive advantage. The research objectives were: (1) Explaining the supply chain for cow's milk at KPSBU, (2) Creating a metric for measuring the performance of the supply chain for cow's milk at KPSBU based on the Supply Chain Operations Reference (SCOR) approach, and (3) Measuring the level of importance (weight) of the metric supply chain performance of cow's milk using Analytical Hierarchy Process (AHP). The method used is descriptive statistical analysis, pairwise comparison, and AHP. Metrics for measuring the performance of the supply chain for cow's milk are used to determine the weight of the supply chain performance metrics, the measured metrics include business processes, performance parameters, work attributes, and performance measurement metrics. The result of the identification of the highest final priority using AHP is the most important factor in the business process, namely the source (procurement) with a weight of 0.51007. Quality is the most important factor in the performance parameter with a weight of 0.51391. In the performance attribute, reliability, namely consumer confidence in KPSBU supply chain management, is the most important factor with a weight of 0.23654. Whereas in the performance measurement matrix the most important factor is delivery performance with a weight of 0.15297, which is the main objective of AHP.

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.
