Salah satu pesaing utama komoditi bawang merah Kintamani adalah bawang merah Brebes. Pangsa pasar bawang merah Brebes lebih besar di bandingkan Kintamani baik pada level lokal Bali maupun nasional. Peningatan mutu komoditi bawah merah Kintamani perlu dilakukan melalui serangkaian perbaikan teknis budidaya agar lebih sesuai dengan kebutuhan dan keinginan konsumen. Tujuan penelitian ini adalah untuk mengetahui kriteria atribut produk bawang merah yang dibutuhkan dan diinginkan oleh konsumen, pembobotan mutu komoditi bawang merah Kintamani dibandingkan bawang merah Brebes, dan aktivitas perbaikan yang harus dilakukan petani Kintamani. Penelitian ini menggunakan metode Quality Fuction Deployment (QFD) dengan alat analisis yaitu matriks House of Quality. Kualitas bawang merah dievaluasi berdasarkan 6 jenis atribut mutu, yaitu kebersihan umbi, warna umbi, ukuran umbi, kesegaran umbi, tidak ada kebusukan pada umbi, dan aroma sedap dengan sekala rating kepentingan 1-5. Responden penelitian adalah 20 orang pedagang sayur di Pasar Kreneng dan Pasar Badung di Kota Denpasar. Hasil penelitian menunjukkan bahwa dari ke-6 atribut mutu bawang merah yang dievaluasi, ukuran umbi memperoleh skor tertinggi dengan rata-rata 4,7 (sangat penting), skor tingkat kepuasan konsumen terhadap kualitas bawang merah Kintamai rata-rata 2,85 (kurang puas), lebih rendah dibandingkan bawang merah Brebes dengan skor 4,55 (sangat puas). Hasil analisis matriks House of Quality menunjukkan bahwa upaya perbaikan yang harus dilakukan oleh petani Kintamani adalah pengendalian hama dan organisme penggangu tanaman (OPT) pada tahapan budidaya bawang merah dengan bobot kepentingan tertingi yaitu sebesar 26%, dibandingkan aktivitas lainnya yang disarankan untuk memperbaiki mutu sesuai dengan kebutuhan dan keinginan konsumen.

The rapid development of internet technology in the modern era has not been fully utilized by farmers resulting in economic disparities among farmers due to product sales through extended supply chains so that there are significant differences in prices for agro-industrial commodities at the farmer and market levels. Meanwhile, farmers are still less interested in reading, resulting in limited knowledge of processing agricultural products to increase economic value. The research aims to design a sales and education system and produce a website for marketing agro-industry products based on an educational website that is good enough. The study was carried out in several stages, namely problem identification, website design using the waterfall method, website testing using the black box method, making questionnaires based on the user acceptance test (UAT), validity and reliability tests, distributing website acceptance questionnaires by users based on the user acceptance test (UAT) and data processing. The research results are to get a website design that combines sales and education systems in one website that is already running well by getting a 100 percent score when tested internally using the black box method. Website acceptance test by users using the user acceptance test (UAT) method results in a design factor of 77.86%, a content factor of 78.75%, and a usability factor of 78.24%. The real test for the entire website scores 78.2% and is included in the good category to be accepted in society.

The transportation of oil palm fresh fruit bunches (FFB) is a crucial stage in the palm oil production system. Productivity and efficiency due to the movement of haul trucks also affect the smooth supply chain of FFB as a material for palm oil mills (PMKS). This paper presents the results of a study that aims to compare the productivity and efficiency of truck movement in the process of evacuating fruit from the yield collection point (TPH) to the PMKS, between direct and transit systems. The efficiency or level of truck utility will affect the supply of FFB for PMKS. In trucks and systems that are less efficient, the FFB supply chain for mills stagnates, which can result in reduced volume and quality of CPO output. The research method is to measure the time of each stage of the FFB evacuation, record the data on the weight of the load, measure the distance traveled, calculate the truck cycle time, productivity level, and the efficiency of the truck movement, then analyze the statistics with the T test. The results showed that there was a difference in performance between transit evacuation system with direct evacuation system to PMKS. In the transit system, truck cycle time = 3.5 hours, truck work efficiency = 44.3%, and truck productivity = 15.4 tons/day. While in direct system, the cycle time = 5.07 hours, work efficiency = 63.3%, and productivity = 12.07 tons/day. Recommendations from the research for improving the FFB supply chain are 1) doubling the supply of FFB from small transport in the transit system, 2) optimizing truck mobility by setting work locations
