Judul: Evaluasi Kinerja, Nilai Tambah, Mitigasi Risiko, dan Peningkatan Kinerja Rantai Pasok Kelapa Sawit: Studi Kasus di PT X
Abstrak: Dalam rantai pasok kelapa sawit, produktivitas dan pasar ekspor kelapa sawit cenderung meningkat dan berimbas negatif pada isu keberlanjutan yang meliputi aspek ekonomi, aspek sosial, dan aspek lingkungan serta terkait langsung dengan rantai pasok. Penelitian ini dilakukan secara terintegrasi untuk mengevaluasi kinerja, nilai tambah, risiko, dan strategi perbaikan kinerja secara berkelanjutan dalam rantai pasok kelapa sawit di PT X. Penilaian kinerja rantai pasok dengan metode SCOR-AHP menunjukkan bahwa tingkat kinerja untuk bagian perkebunan baik (91.24%) dan bagian pengolahan sedang (86.19%). Rasio nilai tambah dilakukan dengan metode Hayami termodifikasi menunjukkan hasil berturut-turut pada perkebunan dan pengolahan adalah 21.86% dan 37.55%. Evaluasi dan mitigasi risiko dengan metode FMEA-HOR, dari 31 kejadian risiko dan 20 sumber risiko, dipilih 8 prioritas sumber risiko yang diberikan aksi penanganan dan diurutkan berdasarkan efektivitas biaya. Untuk mengurangi dampak secara keseluruhan, dilakukan pemilihan strategi peningkatan kinerja rantai pasok kelapa sawit secara berkelanjutan menggunakan metode ANP dengan analisis BOCR (benefit, opportunity, cost, and risk), hasil pembobotan menunjukkan prioritas alternatif strategi perbaikan rancangan produksi.

Judul: Peningkatan Kinerja dan Mitigasi Risiko Rantai Pasok Cangkang Kelapa Sawit (Studi Kasus: Industri Keramik PT X)
Abstrak: Cangkang kelapa sawit (CKS) memiliki potensi sebagai sumber energi alternatif. Hal ini perlu didukung dengan manajemen rantai pasok yang optimal. Penelitian ini bertujuan menganalisis keadaan situasional, keuntungan, kinerja, risiko, dan menentukan strategi peningkatan kinerja. Analisis situasional menggunakan kerangka dari Vorst. Analisis keuntungan dilakukan berdasarkan biaya dan penerimaan. Kinerja dianalisis berdasarkan model supply chain operation reference (SCOR) yang diintegrasikan dengan analytical hierarchy process (AHP). Analisis risiko menggunakan metode house of risk (HOR). Strategi peningkatan kinerja menggunakan metode analytical networking process (ANP) berdasarkan indikator benefit, opportunity, cost, dan risk (BOCR). Terdapat tiga stakeholder utama, yaitu pabrik kelapa sawit sebagai produsen, agen sebagai distributor, dan PT X sebagai konsumen. Analisis keuntungan menunjukan hasil berturut-turut pada pabrik kelapa sawit, agen, dan PT X adalah 77%, 24%, dan 33,6%. Perhitungan kinerja menunjukan bahwa kinerja rantai pasok CKS pada PT X kurang (67,45%). Hasil dari analisis risiko menunjukan terdapat 18 kejadian risiko, 11 sumber risiko prioritas, dan 9 mitigasi risiko prioritas. Alternatif paling potensial dalam peningkatan kinerja rantai pasok adalah pengembangan alternatif sumber pemasok CKS., Palm kernel shell (PKS) have potential as an alternative energy source. This needs to be supported by optimal supply chain management. This study aims to analyze situational conditions, profits, performance, risks and determine performance improvement strategies. Situational analysis using the framework from Vorst. Profit analysis is carried out based on costs and revenues. Performance is analyzed based on the supply chain operation reference (SCOR) model, integrated with the analytical hierarchy process (AHP). Risk analysis uses the house of risk (HOR) method. The performance improvement strategy uses the analytical networking process (ANP) method based on benefit, opportunity, cost, and risk (BOCR). There are three main stakeholders, palm oil mills as producers, agents as distributors, and PT X as consumers. Profit analysis shows that the palm oil mill, agent, and PT X results are 77%, 24%, and 33.6%, respectively. Performance calculations show that the performance of the PKS supply chain at PT X is less (67.45%). The risk analysis results show that there are 18 risk events, 11 priority risk sources, and 9 priority risk mitigations. The most potential alternative in improving supply chain performance is the development of alternative sources of PKS suppliers.

Judul: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
