Judul: Measurement and Improvement of Fresh Milk Supply Chain Performance (Case Study of Mandiri Sejahtera Group, Bogor Regency)
Abstrak: Tantangan industri susu skala kecil berasal dari praktik manajemen bisnis yang masih tradisional dan kurangnya evaluasi kinerja yang komprehensif. Studi ini mengadopsi pendekatan struktural dengan menganalisis kinerja rantai pasokan susu segar di Kelompok Ternak Mandiri Sejahtera, Desa Tajurhalang, Kecamatan Cijeruk, Kabupaten Bogor. Penelitian ini menggunakan metode Supply Chain Operation Research (SCOR) dan Analytical Hierarkhi Process (AHP) untuk analisis kinerja. Data dikumpulkan melalui kuesioner, wawancara, dan observasi. Temuan menunjukkan bahwa kinerja rantai pasok susu segar secara keseluruhan tergolong sedang, dengan skor kinerja 84,25% untuk pemasok pakan, 77,47% untuk Kelompok Mandiri Sejahtera, dan 82,05% untuk konsumen. Secara khusus, area yang perlu ditingkatkan meliputi keandalan, daya tanggap, dan efisiensi biaya. Oleh karena itu, kami telah mengembangkan rekomendasi strategis yang bertujuan untuk meningkatkan efektivitas rantai pasokan, termasuk peningkatan sisim transportasi, pengurangan waktu pemenuhan pesanan dan optimalisasi logistik serta penyimpanan. Implementasi strategi-strategi ini berpotensi memperkuat kolaborasi dan memperkuat hubungan di antara para pemasok, produsen, dan konsumen, sehingga diharapkan berkontribusi pada industri susu yang lebih kuat.

Judul: Analisis Kinerja dan Risiko Rantai Pasok Susu Formula (Studi Kasus: PT Tigaraksa Satria)
Abstrak: Industri produk olahan susu memiliki potensi besar untuk dikembangkan di Indonesia. Namun demikian, baik industri pengolahan maupun distributor masih menghadapi berbagai permasalahan terkait kinerja dan risiko. Penelitian ini bertujuan untuk menganalisis kinerja, risiko, serta menentukan strategi peningkatan kinerja rantai pasok susu formula di PT Tigaraksa Satria. Penelitian ini menggunakan metode supply chain operation reference (SCOR) yang diintegrasi dengan analytical hierarchy process (AHP) untuk analisis kinerja dan metode house of risk (HOR) untuk analisis risiko. Strategi peningkatan kinerja rantai pasok dirumuskan menggunakan metode analytical networking process (ANP) berdasarkan analisis benefit, opportunity, cost, dan risk (BOCR). Hasil pengukuran kinerja menunjukkan bahwa kinerja PT Tigaraksa Satria sudah sangat baik (97,61%). Hasil analisis risiko menunjukkan terdapat 13 risk agent pada tingkat prinsipal dan 18 risk agent pada tingkat distributor. Delapan risk agent ditetapkan sebagai prioritas untuk diberikan aksi mitigasi. Terdapat 8 aksi mitigasi yang dapat diterapkan pada tingkat prinsipal dan 11 aksi pada tingkat distributor. Aksi mitigasi diurutkan berdasarkan tingkat efektivitas dan kesulitan penerapannya. Berdasarkan penilaian pakar, peningkatan koordinasi dan kerja sama antar stakeholder merupakan strategi yang memiliki pengaruh besar terhadap peningkatan kinerja rantai pasok susu formula., The dairy product industry has excellent potential to be developed in Indonesia. However, both the processing industry and distributors still face various problems related to performance and risk. This study aims to analyze the performance, risks and determine strategies for improving the performance of the infant milk formula supply chain at PT Tigaraksa Satria. This study uses the supply chain operation reference (SCOR), which is integrated with the analytical hierarchy process (AHP) for performance analysis and the house of risk (HOR) method for risk analysis. The performance improvement strategy of a supply chain is formulated using the analytical networking process (ANP) based on benefit, opportunity, cost, and risk (BOCR) analysis. The performance measurement results show that the performance of PT Tigaraksa Satria is excellent (97.61%). The results of the risk analysis identified 13 risk agents at the producer level and 18 risk agents at the distributor level. Eight risk agents are set as priorities to be given mitigation actions. Eight mitigations at the producer and 11 acts at the distributor level were proposed to reduce the risk. Mitigation actions are ranked according to the effectiveness and difficulty of implementation. Based on expert judgment, improving coordination and cooperation between stakeholders is a strategy that significantly influences the performance of the infant milk formula supply chain.

Judul: Synthesis of Apatite - Chitosan Composite Using Duck Eggshell and Chitosan with Temperature and pH Control
Abstrak: Composite of apatite-chitosan was prepared by using chitosan as polymer matrix. Calcium phosphate was prepared from CaO and (NH4)2HPO4, which the ratio Ca : P had to be 1.67. Chitosan is produced by deacetilase from biopolymer chitin. Duck eggshell (95% CaCO3) as starting material was converted to be calcium oxide (CaO) through calcinations with temperature 1000oC for 5 hours. In-situ and ex-situ methods were prepared from apatite and chitosan (dissolved with acetate acid 2%). Calcium phosphate prepared for bone implantation, but it is too fragile and brittle to be implant into the body. So addition of chitosan can decrease crystalinity and increase mechanic characteristic (tougher). Composite apatite-chitosan was resulted by fast precipitation. Fast precipitation was held in a breaker glass with nitrogen atmosphere, under controlled temperature at 37oC and pH 7, in order to increase amount of hydroxyapatite. Precipitation with CaO which was dropped by (NH4)2HPO4. Hydroxyapatite and chitosan were appearing at samples with in-situ and ex-situ methods which indicating by peak matching of XRD (closed lattice parameter, crystal size), overlapping at FTIR spectra and supporting by SEM picture (homogenous and agglomerated particle). However, it still needs further research to examine biocompatibility osteoconductive degree of sample by in-vivo and in-vitro test.
