A good logistics service performance in the dairy feed mill increases farmer benefits and reduces negative environmental effect. Therefore, this study aims to measure the effectiveness of logistics services quality in dairy cooperative feed mill using the customer satisfaction index (CSI) method and important performance analysis (IPA) to enhance performance quality in achieving sustainable business processes. This was conducted in Lembang Districts, West Java, Indonesia, with 150 farmer members of the cooperative as respondents. Then, a total of 100 questionnaires that is suitable with the analysis criteria were used. The CSI method was used to determine farmers’ perception of the logistics service performance and the IPA was adopted for selecting the attributes that need improvement. The result showed a CSI value of 71.05%, which falls under the satisfied category and the IPA diagram showed that the responding rate toward farmers’ demand and employees’ willingness to help was in quadrant II. Conclusively, the logistics service in the cooperative is effective to fulfil farmer needs. Furthermore, some attributes in quadrant II are useful recommendations for improving the logistics service quality.

Types of forage and the altitude it grows affect the quality of milk’s fatty acids (FA) profile. Thus, this study aimed to analyze the chemical and FA quality of elephant grass (EG) and king grass (KG) growth from different altitudes. The grass samples were collected from Pangalengan District, the highland, and Dramaga District, the lowland. Grass lipid extraction and FA methylation were done according to the AOAC method. FA was quantified using gas chromatography (GC-7820A), CP-Sil 88 fused-silica capillary column, and authentic standard (Supelco 37 Component FAME-Mix). The nutrient content was analyzed using FT-NIR Spectrometer Solids Cell, except for EE used the AOAC method. This study showed EE content was significantly different between species, with the higher content found in EG. The C17:0 was significantly different between altitudes. The SFA, UFA, and PUFA were significantly different between species. The EG had higher UFA and PUFA and lower SFA. It showed that the higher EE content was related to the higher FAs yield, followed by higher UFA and PUFA in EG than in KG. It was concluded that the grass species had a more significant effect on chemical and FAs profiles than the altitude.

Environmental and land pressure from horticultural and tourism reduces the availability of forage for sustainable dairy production, specifically in Lembang. Subsequently, only limited commercialization of forage exists in the area. This study aims to explore the perception and selections of dairy farmers in Lembang District based on their interest in purchasing forage and its varieties. The purposive sampling technique was used to select hundreds farmers and they were interviewed for their perception. These perceptions were grouped into (1) not very interested, (2) not interested, (3) interested and (4) very interested. The data were analyzed using scale range analysis. However, the ones concerning the selection of forage types and the willingness of farmers to purchase this plant material were analyzed using qualitative analysis and descriptive statistics. The results showed that 96% were willing to purchase forage (interested and very interested) with elephant grass being the most favourable type (62%). It was found that quality is the critical determinant in farmers decision to purchase forage (33%). Therefore, it was concluded that sustainable dairy farming in the district can be improved by purchasing high-quality elephant grass forage from outside this region.
