Abstract

The increase in the use of chemical fertilizers on agricultural land has occurred more rapidly since the green revolution era. The use of chemical fertilizers is increasingly worrying because it has a huge impact on the survival of living things. The use of organic fertilizers such as compost is an alternative that can be selected to reduce the use of chemical fertilizers. Compost is produced from a mixture of organic materials, both organic matter derived from livestock and organic matter from plants. The compost process technology needs to be disseminated to the community, especially farmers. This activity aims to increase the technological knowledge capacity of members of farmer/livestock groups in utilizing cattle feces waste. Technology dissemination activities were carried out at the “Balumbungan” Farmer/Livestock Group in Bontonompo Village, Bontonompo District, Gowa Regency. The application of local microorganisms (LoM) from natural materials (rice waste) as a decomposer has been applied in the process of making compost made from cow feces combined with laying hen feces. Rice waste contains carbohydrates which are a good source of energy for the survival of microorganisms. Utilization of LoM as a decomposer in the fermentation process of organic materials is an attempt to utilize natural materials that have been wasted so far. Rice waste is a good growth medium for bacteria and fungi that are important for plants. The final result of the activity is increasing partner capacity in utilizing fecal waste into compost. Keywords: compost, dissemination, feces, decomposer, organic fertilizer

Abstract

Sipatuo Farmers Group is the Dairy Cow Farmer Group in Enrekang Regency, South Sulawesi. Their main income is Dangke, which is a local cheese. Dangke production is highly dependent on milk production and quality. The farmer's problems are low production and quality of Holstein Friesian milk, high production costs, expensive concentrate, and the farmers holding limited arable pastures that are not high enough to provide feed for cows. Chemical fertilizer input is one way to increase the dry matter (DM) yield of forage. However, the prices are increasing by more than 100%. Thus, the objective of this program is to implement the alley cropping system to increase DM yield and pasture quality. The program begins with socialization, sharing knowledge, and discussion with the farmers, and the next day continues with transplanting Indigofera zollingeriana to Pennisetum purpureum pasture for arranging the alley cropping system. Implementing this system not only increases the DM yield and forage quality but also reduces fertilizer costs. High DM yield and pasture quality will provide pasture to meet the target of increasing milk production and quality. The increase in milk production and quality will increase Dangke production, it leads increasing the farmers' life. Keywords: alley cropping system, dangke, Indigofera

Abstract

The lactation phase of dairy cows is very important in determining the quality of milk produced. The lactation phase is divided into three phases: early, mid, and late lactation. The objective of this study was to determine the milk quality and percentage of curd and whey of Holstein Friesian dairy cows at different lactation phases. This study was conducted using a completely randomized design (CRD) with 3 treatments and 5 replicates of each treatment. The treatments in this study were P1 = early lactation, P2 = middle lactation, and P3 = late lactation. The research data were processed through the SPSS application using the ANOVA test, and if there was a difference between treatments, it would be further tested using the Duncan test. The lactation phase significantly affected (P < 0.05) the fat content and curd production of Holstein Friesian cow milk, but did not significantly affect the protein content, pH, specific gravity (SG), and viscosity of Holstein Friesian cow milk. The lactation phase has a significant impact on the milk quality and percentage of curd and whey in Holstein Friesian dairy cows. It has been observed that during the late lactation phase, the milk quality tends to be higher, which is a noteworthy finding for dairy farmers. Keywords: Phase of lactation, physical quality, chemical quality, curd, and whey
