The analysis of the ratio normative consumption per capita to cereal production shows that 39.66% of districts in Indonesia experience a deficit in food availability, partly due to population growth which an increase has not matched in cereal production. The purpose of this research is to perform forecasting on the amount of grain production as a reference in formulating a strategy for supplying grain to the population to fulfil the staple food consumption needs of the Indonesian population. This research method uses secondary data on grain production in Indonesia with a range of 2000-2021, and forecasting is carried out until 2024. The data source comes from the Central Statistics Agency (BPS), and data processing uses SPSS (Statistical Package for Social Science). Forecasting techniques use four methods: simple moving average, weight moving average, exponential smoothing and double exponential smoothing. Forecasting results for grain production in 2000-2024 were below actual production, and the peak of production increase occurred in 2017 and then decreased production until forecasting in 2024. The lowest values for MAD, MSE and MAPE were for forecasting results using the WMA method.","PeriodicalId":397828,"journal":{"name":"AGRITROPICA : Journal of Agricultural Sciences","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121976589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research used 123 blood samples of male and female Sikumbang Jonti ducks. The ducks were eight weeks old and kept intensively at the UPT Fakultas Peternakan Universitas Andalas. Blood samples of Sikumbang Jonti ducks were taken through the brachial vein as much as ± 2 mL. The Genomic DNA Purification Kit (Promega) protocol isolated DNA from blood samples. A pair of primers F amplified the total DNA: 5'-GGA CAG CCT GAG GAA AGA GT-3 'and R: 5'-GTG GAA GGT GGG GAG ACT TC-3', which produced a fragment region of the GH gene exon 3 with a cut region of part intron two and part intron 3 with a primary length of 833 bp. The amplified product was restricted by the enzyme TasI which recognizes the cutting site (↓AATT). Based on the restriction results, two (2) genotypes were obtained, namely homozygous (-/-) as many as four (4) and homozygous (+/+) as many as 119. The analysis of restriction products included the allele frequency, namely the allele (+) of 0.98 and the allele (-) of 0.02, and genotypes frequency of homozygous (-/-) of 0.03 and homozygous genotypes (+/+) of 0.97. The diversity of the GH gene is in the Hardy-Weinberg equilibrium. Based on the research results, it can be concluded that there is diversity in the GH gene of the Sikumbang Jonti duck, and it is in the Hardy-Weinberg equilibrium, so it can be used as a candidate for the genetic marker of ducks.","PeriodicalId":397828,"journal":{"name":"AGRITROPICA : Journal of Agricultural Sciences","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116350569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to determine the optimal combination of Pakchong and Indigofera to increase body weight in Bali cattle. The research was conducted in UPTD. BPTHTM Serading, Sumbawa , NTB Province. This study used 28 male Bali Cattle aged 2-3 years. Livestock were randomly divided into four feed groups, namely seven cattle-fed elephant grass 70% and lamtoro 30% (P0), 70% pakchong grass and 30% indigofera (P1), 60% pakchong grass and 40% Indigofera (P2), 50% pakchong grass and 50% Indigofera (P3).

One alternative that can be done is substituting wheat flour with other flour, for example, banana flour. In their manufacture, cookies substituted for banana flour produce a brown color that is not preferred. Therefore, to fix this, in making cookies, the addition of green moringa leaf flour is carried out. Besides being expected to improve the cookies' color, Moringa leaf flour also contains good nutrients. Moringa leaf flour contains protein, minerals, vitamins, essential amino acids, and antioxidants. The nutrients contained in moringa leaf flour have the potential to be nutritious food additives and beneficial to health. The purpose of this study was to determine the effect of the addition of moringa leaf flour on wheat flour cookies and banana flour on physical characteristics (moisture content, color, and texture), chemical characteristics (protein content and ash content), and organoleptic (color, aroma, taste, texture, and overalls). This study used a complete randomized design (CRD) with 1 factor: the percentage of addition of Moringa leaf flour, 0%, 2.5%, 5%, 7.5%, and 10%. Adding Moringa leaves to manufacture cookies from wheat flour and banana flour significantly affects the moisture content, texture, color, protein content, and ash content of the cookies produced. The most preferred cookies are cookies with the addition of 5% moringa leaf flour.","PeriodicalId":397828,"journal":{"name":"AGRITROPICA : Journal of Agricultural Sciences","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121173317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, catfish meat is believed to be capable of preventing heart and cardiovascular disease because its unsaturated fats. Catfish skin can be used as a source of collagen in the culinary, cosmetic, and health fields. Catfish spawn all year round because of the abundance of food. The environment can help stimulate the synthesis of reproductive hormones in the reproductive activity of catfish. Environmental manipulations such as temperature, pH and salinity have different effects on the hatchability of catfish (Pangasius sp.) eggs. High temperatures can speed up the hatching time of the eggs but drop the hatching percentage and survival rate because high temperature activates the chorionase enzyme containing pseudokeratin which softens fish egg shells. In contrast to the pH treatment, a pH that is too acidic will deactivate the work of the chorionase enzyme so that the shells of fish eggs are difficult to break, resulting in a low percentage of hatching and survival rate with the longest hatching time. Salinity works by balancing the osmoregulatory pressure in the shell with the environment. A high salinity concentration can damage the egg by breaking into and swelling the eggshell, causing a low survival rate. On the other hand, eggs not treated with salinity were reported to have the lowest hatching percentage due to fungi attacking the eggs causing embryos to die. Salinity does not affect egg hatching time.","PeriodicalId":397828,"journal":{"name":"AGRITROPICA : Journal of Agricultural Sciences","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117021572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
