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: Sistem penunjang keputusan manajemen Rantai Pasok Karet Alam dengan pendekatan Sustainable Balanced Scorecard di PT. X
Abstrak: Sistem penunjang keputusan (SPK) dapat digunakan untuk melakukan evaluasi kinerja dan pengambilan keputusan di dalam manajemen rantai pasok dengan lebih efisien sehingga dapat meningkatan produktivitas dari agroindustri karet alam. Penelitian ini bertujuan untuk mengidentifikasi rantai pasok karet alam serta merancang model pengambilan keputusan dan model pengukuran kinerja rantai pasok dengan menggunakan pendekatan sustainable balanced scorecard dan selanjutnya menggunakan model tersebut untuk mengembangkan SPK. Penelitian ini dilakukan dengan menggunakan pendekatan sistem. Dalam penelitian ini juga dilakukan analisis seven green waste untuk penggambaran green value stream map (GVSM) yang menunjukan bahwa terdapat potensi penghematan air sebesar 1 877 364 liter dan energi sebesar 761 kWh perbulan dalam proses produksi ribbed smoked sheet (RSS) di salah satu kebun karet milik PT. X. Hasil penilaian pakar pada model pemilihan strategi peningkatan mutu lateks dengan metode fuzzy AHP merekomendasikan adanya perbaikan perilaku sadap. Hasil penilaian pakar pada model pemilihan strategi peningkatan kinerja rantai pasok dengan metode analisis SWOT merekomendasikan strategi penekanan biaya produksi dengan melakukan berbagai efisiensi dan pengutamaan kualitas produk sebagai nilai saing utama dengan perusahaan lain. Pembobotan indikator kinerja utama (IKU) dengan metode fuzzy AHP di dalam model pengukuran kinerja menunjukan bahwa perspektif pelanggan memiliki bobot kepentingan yang paling besar sebesar 0.318 sedangkan IKU dengan bobot yang paling besar adalah net profit margin yang dipicu oleh penurunan biaya operasional rantai pasok karet alam. Model-model ini diterjemahkan dalam pemodelan berorientasi obyek yang kemudian diimplementasikan dalam sebuah paket program komputer yang akan membantu pengguna SPK dalam menentukan keputusan dan melakukan pengukuran kinerja., Decision support system (DSS) can be used for performance evaluation and decision making in supply chain management to increase the productivity of natural rubber agroindustry. This research objectives were to identify the natural rubber supply chain decision-making models and to formulate its performance measurement model by using sustainable balanced scorecard approach and then to develop a decision support system prototype. This study was conducted by using a systems approach. This study also analyzed seven green waste to describe the green value stream map (GVSM), the result shown that there is a potential savings of 1 877 364 liters of water and an energy of 761 kWh per month in the ribbed smoked sheet (RSS) production process in one of the gardens owned by PT. X. The results of expert judgment by using fuzzy AHP method in latex quality improvement strategy selection model shown that there are some needs of tapping behavior improvement. The results of expert judgment in supply chain performance improvement strategies selection model of by SWOT analysis method recommended cost reduction strategy by perform several production efficiency and using product quality as the key value to compete with other companies. Weighting of key performance indicators (KPI) with fuzzy AHP method in performance measurement model shown that the customer perspective has the greatest importance weight of 0.318 while the KPI with the greatest weight is net profit margin which is triggered by a decrease in operating costs of natural rubber supply chain. These models were translated into an object-oriented modeling and implemented in a package of computer programs that could assist users in decision

Judul: Biology and ecology of the buffalo fly, haematobia exigua de meijere (diptera:muscidae)
Abstrak: The life history of the buffalo fly was observed at room temperature of 27°-29.5°C and at a relative humidity of 48-68 percent. The eggs hatched after 17-22 hours, with an average of 18 hours. First instar larvae measured 1.25 + 0.16 mm long and 0.27 + 0.037 mm wide. reach the second larval stage. It took 6-12 hours to the second instar larvae measured 2.676 +0.187 mm long and 0.353 +0.028 mm wide. The second instar took about 12-24 hours to reach the third larval stage. The third instar measured 6.833 + 0.189 mm long and 0.919 + 0.051 mm wide. It took about 2-3 days for the third instar to become pupae. Duration of the pupal stage was about 5-7 days before the adults emerged. Under laboratory condition, the buffalo fly completed its life cycle in 9.5 to 10.5 days, whereas under field condition it took 9-14 days with an average of 10.5 days. The growth ratio which was based on the measurements of the cephalo-pharyngeal skeleton of each instar was 1.797. The preoviposition period was 8-12 days and mating usually occurred on the 6th or 7th day. The longevity of the male was 29 days, whereas it was 32 days in the female. The range of egg production under laboratory condition was between 20-139 per female fly. The belly and hind legs of the carabao were the most preferred habitat either during cloudy and cool dry or shiny and warm day. When the weather was clear and the carabao was in the shade, the flies tended to be more distributed particularly on the shoulder, dewlap, back and horns. The carabaos had relatively fewer Musca sp. and Stomoxys calcitrans than cattle; never the less carabaos had a higher infestation of buffalo fly than cattle. Oviposition occured either during the day or night but the buffalo flies were more active during the night than in the day time. The effect of various lengths of exposure time of manure in relation to the oviposition was profound. observed, the maximum number of the buffalo flies was occurred when the dung was exposed for 30 minutes. With increasing time of exposure the number and variety of insects also increase. It was evident that Sepsidae and psychodidae were the most dominant insects emerging from the dung. The number of buffalo flies also increased with increasing
