Rice is one of the staple food in Indonesia which is easy to serve and contain high level carbohydrate, thus influenced the daily activities and human health. The aim of this research is producing low glucose healthy parboiled rice and obtaining the chemical content of Mekongga parboiled rice. This research was held Chemistry Laboratory of Mathematics and Natural Science Faculty, Tadulako University. This research used Mekongga parboiled rice which used completely randomized design with one factor, i.e. kind of treatments, P1 (water soaking with 300 C + steaming for 20 min), P2 (water soaking with 400 C + steaming for 20 min), P3 (water soaking with 500 C + steaming for 20 min), P4 (without water soaking + steaming for 20 min), P5 (without treatment (Control)). Water content, ash content, starch content and sugar reduction were observed in this research. Water soaking with 300 C + steaming for 20 min treatment showed the best result if compared with other treatments in water content level (9.28%), ash content (0.798%), starch content (65.71%), sugar reduction (0.71%), and amylose (23.75%).

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).
