The role of nutmeg in traditional and international trade is very significant because it is able to supply around 60-75 percent of the world's market share needs. The government as one of the market players has a role in creating strategic agricultural product price stabilization, and while there are still weaknesses of the agribusiness structure prevailing in Indonesia, integration analysis is very important given the benefits of knowledge about market integration. Market integration is useful to facilitate monitoring of price changes and support government policies on price stabilization and predict prices in the domestic market. Analysis of the market integration of this research uses the Vector Autoregression (VAR) model in difference determined through data stationarity test. Meanwhile, to determine the impact of the response of each variable due to shock (impulse response analysis) and Variance Decomposition. This research has three equations in the VAR analysis model and the results are all significant. The benefit of this research is to help determine the forecast of nutmeg prices in the domestic market and the impact of the response of each variable due to shocks.

This research aims to assess the NPK nutrient content of liquid organic fertilizers from various types of rice washing water. This research was conducted in September 2020 at Sidondo III Village, Sigi Biromaru District, Sigi Regency and the Soil Laboratory of the Faculty of Agriculture, Tadulako University. This study was designed using a completely randomized design (CRD) with 5 treatments, namely P0 (without rice water), P1 (white rice washing water), P2 (white glutinous rice washing water), P3 (black glutinous rice washing water), and P4 (red glutinous rice washing water), the treatment was repeated 4 times so that there were 20 experimental units. The observation parameters in this research were the observation of temperature, pH, POC color, and aroma of POC during the fermentation process as well as the N, P, and K content in the resulting POC. The results showed that the treatment with the addition of washing water for white glutinous rice (P2) produced the highest content compared to other treatments with an N content of 0.15%, but in the observation of P and K content, the addition of washing water for red glutinous rice (P4) gave the results. the highest with a P content of 0.09% and K of 0.14% but not different from the addition of washing water for white glutinous rice (P2).

Purple sweet potato is a source of anthocyanins that function as antioxidants, antimutagenic, and anti-carcinogenic so that it has the potential to be processed into various functional food products. The stability of anthocyanin levels in the product is greatly influenced by temperature during processing, where the use of high temperatures will damage and reduce anthocyanin levels. This research was conducted to determine the effect of processing and combination of raw materials on anthocyanin levels and antioxidant activity of tortilla products made from a combination of purple sweet potato (Ipomoea batatas L) and cassava. The research design used a completely randomized design, with the object of research being tortillas made from purple sweet potato obtained from Palolo District, Sigi Regency, Central Sulawesi Province, combined with cassava obtained from the local market in Palu City, Central Sulawesi Province. The results showed that the anthocyanin levels of tortilla products varied from 5% (P1) to 19.63% (P5). There was a very significant decrease in anthocyanin levels around 68.26 - 91.91%. The amount of antioxidant activity was measured by IC50, wherefrom the research it was known that the IC50 value of tortilla products ranged from 242.68 to 155.66 µg / ml which indicated that the antioxidant activity of tortilla products was weak and even almost inactive. Based on the results of the study, it is indicated that the processing of purple sweet potatoes into tortillas is not appropriate because the processing is predominantly using high temperatures so that it can damage the anthocyanin content and reduce antioxidant activity.
