ABSTRACT<br /><br />Sago palm is a carbohydrate source which has the highest carbohydrate content compared to the other crops. It can produce about 200-400 kg per trunk of sago dry starch. More than 50% sago palm population in the world are grown in Indonesia and 90% sago palm in Indonesia is found in Papua. This research was aimed to characterize several sago palm accessions in South Sorong District, West Papua. There were 12 accessions observed, i.e. Fasai, Fasampe, Falia, Fanomik, Fasongka, Fafion, Fakattao, Fanke, Fablen, Failik, Fakreit and Fasinan. Among these accessions, there were many differences based on morphological characteristics such as shoots color, crown shape, trunk height, number of leaf, existence of spine, starch content, also pith and starch color. Fablen was the only non-spiny type. Most of sago accessions were high yielding accessions with the potential yield more than 200 kg per trunk of sago dry starch. Fanomik had the highest potential yield. Sago palm productivity in the natural forest of Saifi Subdistrict, South Sorong District, West Papua was estimated to reach approximately 34.59 ton ha-1 per year of sago dry starch.   <br /><br />Keywords: accessions, starch, yield, food

Papua and West Papua Province have the large potential of sago palm (Metroxylon sagu), however, until now the production and utilization is very low compared with its potential. This is because of most farmers in this area still use traditional method in processing sago.  The traditional method is labour intensive and time consuming process.  Sago farmers in this area still apply traditional ways to process sago starch due to the lack of processing machines. The objective of this research was to conduct field testing of sago processing  machine produced by Agroindustry Machinery Workshop of Papua University. The machines that have been tested consist of cylinder type sago rasping machine and stirrer rotary blade sago starch extraction machine. The machine’s performance under field condition was evaluated by measuring parameters (a) rasping capacity, (b) extraction capacity, (c) starch percentage, (d) starch yield and (e) starch loss in waste. Results showed that all parts of the machine are functioning properly and farmers can easily operate the machine.  The performances of the machines under field condition were (a) rasping capacity 1,159. 8 kg/hour, (b) extraction capacity 243.8 kg/hour, (c) starch percentage 38.26 %, (d) starch yield 93 kg/hour   and (e) starch loss in waste 1.03 %.   Keywords: cylinder type, field test, rasping machine, sago processing, starch percentage

As an important carbohydrate-source food crop and raw materials of starch-based industries,  accelerated cassava breeding has been extensively pursued through various procedures, among others, is mutant induction using gamma irradiation combined with molecular marker. Iding, a local genotype cassava has been compared with a national variety Adira 4 for its yield attributes following gamma irradiation at various dose levels ( 2, 20, 30, and 50 krad). The mutation rate was conducted based on morphological characteristics and identification using RAPD by employing random primer OPB-10. Evaluation was conducted on mutant lines producing high potential yield,  high starch and amylose contents. The fourth generation of irradiated Adira 4 (2 and 30 krad) and Iding (2 krad) exhibited higher yield and amylose content as compared to their representative controls. The yield of 30 krad irradiated Adira 4 indicated by mean tuber weight per individual could reach more than twice of that of control and almost 1.5 times of that irradiated with 2 krad. The levels of amylose content of all irradiated ones, regardless of genotypes and gamma irradiation doses  (2 and 30 krad) were higher than that of control. In most parameters, irradiated Adira 4 was superior to irradiated Iding.

Modern sweet corn is distinguished from other vegetable corns by the presence of one or more recessive alleles within the maize endosperm starch synthesis pathway. This results in reduced starch content and increased sugar concentration when consumed fresh. Fresh sweet corn originated in the USA and has since been introduced in countries around the World with increasing popularity as a favored vegetable choice. Several reviews have been published recently on endosperm genetics, breeding, and physiology that focus on the basic biology and uses in the US. However, new questions concerning sustainability, environmental care, and climate change, along with the introduction of sweet corn in other countries have produced a variety of new uses and research activities. This review is a summary of the sweet corn research published during the five years preceding 2021.

Abstract Introduction Colorectal carcinoma (CRC) is the most common gastrointestinal neoplasm in the world, accounting for 15% of cancer-related deaths. This condition is related to different molecular pathways, among them the recently described serrated pathway, whose characteristic entities, serrated lesions, have undergone important changes in their names and diagnostic criteria in the past thirty years. The multiplicity of denominations and criteria over the last years may be responsible for the low interobserver concordance (IOC) described in the literature. Objectives The present study aims to describe the evolution in classification of serrated lesions, based on the last three publications of the World Health Organization (WHO) and the reproducibility of these criteria by pathologists, based on the evaluation of the IOC. Methods A search was conducted in the PubMed, ResearchGate and Portal Capes databases, with the following terms: sessile serrated lesion; serrated lesions; serrated adenoma; interobserver concordance; and reproducibility. Articles published since 1990 were researched. Results and Discussion The classification of serrated lesions in the past thirty years showed different denominations and diagnostic criteria. The reproducibility and IOC of these criteria in the literature, based on the kappa coefficient, varied in most studies, from very poor to moderate. Conclusions Interobserver concordance and the reproducibility of microscopic criteria may represent a limitation for the diagnosis and appropriate management of these lesions. It is necessary to investigate diagnostic tools to improve the performance of the pathologist's evaluation, for better concordance, and, consequently, adequate diagnosis and treatment.
