A study was carried out to determine the physicochemical characteristics of sago hampas and sago wastewater from sago processing mill in Luwu Regency. The sago hampas was used is the residue of sago starch filtration of unrefined raw fiber. The sago wastewater was taken from processing mill are discharged into river. The points of sago wastewater sampling were undertaken in three different points, namely first wastewater (A1), the last wastewater (A2), and water that has been discharged into the river (A3). The sago hampas and sago wastewater processing mill was obtained by Spectrofotometric, Atomic Adsorption Spectroscopy, and analytical methods. The sago hampas content was found at C-Organic 33.01%; N-total 1.66%; C/N ratio 20; P2O5 0.04%, and minerals which are Calsium 27716 ppm, Magnesium 4247 ppm, and Sulfur 743 ppm. COD concentration sago from wastewater was found at A3 point which is 177.3985 mg/l; N-total 0.1%; Phospor 0.01 ppm; Kalium 10.46 ppm; Magnesium 5.84 ppm; and Calsium 0.62 ppm. The high content of organic materials and minerals in sago hampas and sago wastewater needs to be processed before discharging it into the river. The results of this study indicate that sago waste can be used as a feedstock biogas production.

PHYSICOCHEMICAL CHARACTERISTICS OF SAGO STARCH OBTAINED FROM FLUIDIZED BED DRYING USING SOLAR AND BIOMASS POWERED CROSS FLOW FLUIDIZED BED DRYER. The research aim is to study the comparative quality of sago starch drying results using cross flow fluidized bed dryer powered by solar and biomass in conventional drying, particularly the chemical composition and physicochemical characteristics. This research was conducted through a drying phase of wet sago starch using a cross flow fluidized bed dryer, and drying in conventional as well as dried sago starch quality testing results are drying. The results of this study indicate that dry sago starch which has been drained by means of cross flow fluidized bed dryer has a chemical composition that does not vary much with starch which is dried by conventional drying, so that the dried sago starch produced by the dryer is very good. On the other hand the use of dryers is the more correct because the physicochemical properties of sago starch using a low drying temperature and drying time is short. Tujuan penelitian ini adalah mempelajari perbandingan kualitas pati sagu hasil pengeringan menggunakan alat pengering cross flow fluidized bed bertenaga surya dan biomassa dengan pengeringan secara konvensional, khususnya komposisi kimia dan karakteristik fisikokimia. Penelitian ini dilakukan melalui beberapa tahapan yaitu pengeringan pati sagu basah menggunakan alat pengering cross flow fluidized bed, pengeringan secara konvensional serta pengujian kualitas pati sagu kering hasil pengeringan. Hasil dari penelitian ini menunjukkan bahwa pati sagu kering yang telah dikeringkan dengan alat pengering cross flow fluidized bed memiliki komposisi kimia yang tidak berbeda jauh dengan pati yang dikeringkan dengan cara pengeringan secara konvensional, sehingga pati sagu kering yang dihasilkan oleh alat pengering tersebut sangat baik. Di sisi lain penggunaan alat pengering ini semakin memperbaiki sifat fisikokimia pati sagu sebab menggunakan suhu pengeringan yang rendah dan waktu pengeringan yang singkat.   Kata Kunci: pengering unggun terfluidakan; fisikokimia; pati sagu

Up to now the Agriculture Ministry of Republic of Indonesia has released 19 varieties of hybrid rice. Hipa 6 Jete and Hipa 7 varieties are two of them. Hybrid rice is a group of rice plants formed from first generation individuals (F1) derivative of a combination of crossing between certain elders. Hybrid rice superior varieties has a higher yield potential than inbred superior varieties that dominate rice cultivation areas. Rice quality is one of the factors that determine the level of consumer acceptance of a variety. The rice quality is influenced by several factors such as physical quality, cooking quality and taste quality. This paper aims to review the physical quality, milling quality and physical properties of Hipa 6 Jete and Hipa 7. The length of Hipa 6 Jete and Hipa 7 are long and the shape are slender. Based on the head rice and broken rice percentage both Hipa 6 Jete and Hipa 7 are met the medium 2 and 3 quality class (SNI 6128:2015). Based on the physicochemical characteristics both Hipa 6 Jete and Hipa 7 are classified as intermediate amylose content with soft gel consistency and with high intermediate gelatinization temperature. In cooling condition the cooked rice of Hipa 6 Jete and Hipa 7 are soft texture.

Biogas has become one of the most attractive pathways among the renewable energy sources essential to address major modern challenges such as climate change and energy depletion in recent years. Biogas derives from the degradation of organic materials through anaerobic digestion by microorganisms. Such organic materials generally come from waste feedstocks. Therefore, besides being a sustainable replacement for fossil fuels, biogas helps control waste. Agricultural and industrial residues, municipal organic waste and sewage sludge are thus common feedstock sources, including seeds, grains and sugars, lignocellulosic biomass such as crop residues and woody crops, or high carbohydrate algae. Because of its versatility in usage and storage space, biogas plays an significant role in managing potential electricity grids. Through biogas production and utilisation, our society can go deeper into green energy applications. This Chapter will give an introduction the the current energy sector and where biogas can be used as a substitute for decarbonisation of the energy sector.

AbstractRenewable energy is collected through sustainable natural processes. One of the examples of renewable energy is a biofuel. A biofuel is produced from organic materials, such as plants with high sugar content. Sago starch extracted from sago pith contains starch and fiber that can be converted into glucose by hydrolysis. Sago starch and fiber can be processed into bioethanol as the main ingredient of renewable energy source. In this study, bioethanol production from sago waste fermented by baker’s yeast and tapai underwent the following stages: delignification, hydrolysis, fermentation, and distillation. The highest bioethanol content was obtained from the BRT treatment where wet solid sago waste was fermented by baker’s yeast (45.7021%), while the lowest was found in the BTP treatment (0.9504%). Two or more than two peaks were shown by the ART, ATP, BTP, and KTP treatments, whereas only one peak was indicated by the BRT and KRT treatments suggesting that there was only one compound that can be identified as ethanol.
