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: Performance Analysis of Fresh Milk Outbound Logistics at North Bandung Cattle Farmer Cooperative, Lembang
Abstrak: Koperasi Peternak Sapi Bandung Utara (KPSBU) merupakan koperasi primer tunggal usaha di Lembang berperan sebagai wadah bagi peternak sapi perah di kawasan tersebut dalam memproduksi susu segar berkualitas untuk disalurkan menuju ke pelanggan yaitu PT X, PT Y dan konsumen langsung. Penyaluran susu segar ke pelanggan merupakan pergerakan produk keluar dari pabrik menuju konsumen atau disebut outbound logistik. Aktivitas selama proses outbound logistik merupakan aktivitas primer yang perlu diperhatikan kinerjanya dan kualitas produk yang dihasilkan. Penelitian ini bertujuan untuk mengukur kinerja outbound logistik susu segar di KPSBU Lembang dan kualitas susu segar selama proses outbound logistik. Metode analisis yang digunakan untuk mengukur kinerja outbound logistik susu segar adalah supply chain operation reference-analytical hierarchy process (SCOR-AHP). Pengujian kualitas susu segar meliputi kandungan total bahan kering, protein, lemak, pH, berat jenis dan total jumlah bakteri. Data dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa nilai kinerja outbond logistik susu segar di KPSBU Lembang yaitu 90,20% (good). Kualitas susu segar selama proses outbound logistik telah memenuhi standar mutu yang diminta pelanggan dan SNI 3141.1.2011., North Bandung Cattle Farmer Cooperative (KPSBU) is the single primary cooperative business in Lembang which acts as a forum for dairy farmers in that area to produce quality fresh milk to be distributed to customers. The fresh milk was sold to PT X, PT Y and direct selling to consumers. Distribution of fresh milk to customers is the movement of products out of the factory to consumers, it is called as outbound logistics. The activities during the outbound logistics process mentioned as primary activities that needs attention to their performance and quality of the product. This study was aimed to analyze the performance of the outbound logistics of fresh milk at KPSBU Lembang and quality of fresh milk during the outbound logistics process. The supply chain operation reference-analytical hierarchy process (SCOR-AHP) method was used to analyze the logistics performance. The quality of fresh milk observed included total solid, protein, fat, pH, specific gravity and total plate count. The obtained data were analyzed descriptively. The results showed that the performance of outbound logistics of fresh milk at KPSBU Lembang fell into the good category (90,20%). The quality of fresh milk during the outbound logistics process from cooperative to the dairy industry and direct consumers was met the quality standards of customer demand and SNI 3141.1.2011.

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.
