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: 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: 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.
