High fiber consumption has been linked to diabetes prevention. The production of flakes derived from KBB has the potential to facilitate individuals in incorporating high-fiber food items into their daily diets. Nevertheless, the utilization of just Yellow KBB flour yields flakes that are deemed undesirable by consumers due to their firm consistency and deep hue. The substitution of Yellow KBB flour with a combination of wheat flour and mocaf has the potential to enhance the physical characteristics of the resulting flakes. The objective of this study is to assess the physical attributes of flakes derived from KBB. This particular flake was produced using a series of five distinct formulations. The present study employed a completely randomized design (CRD) with three replications. The formulas consist the proportions of wheat flour (WF), mocaf flour (MF), and Yellow Kepok banana bud (KBB). The following are the five ratios: (100%:0%:0%), (50%:50%:0%), (50%:37.5%:12.5%), (50%:25%:25%), and (50%:37.5%:12.5%). The water absorption, swelling ability, texture, and color of flakes produced from wheat, mocaf, and KBB flour were examined. The F2 sample, consisting of a composition of 50% wheat flour, 37.5% mocaf flour, and 12.5% yellow KBB flour, exhibited the highest water absorption value (63.19%) among all the samples. In addition to this, F2 can be characterized as a specimen exhibiting a relatively low level of hardness (1.63 N) and a correspondingly low fracture value (2.08 N). The F2 flakes had a much higher brightness value (37.06) in comparison to the other samples used yellow KBB flour.","PeriodicalId":509812,"journal":{"name":"Jurnal Keteknikan Pertanian","volume":"38 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140743136","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}

Various nutrient dosing control systems, such as on/off, fuzzy logic, and K-NN, have been widely discussed by many researchers. Nevertheless, there has been limited discourse regarding the employed dosing methods, namely sensor-based nutrient dosing and nutrient dosing based on the nutritional dilution equation. The objective of this study was to assess the effectiveness and efficiency of three nutrient dosing methods that can be used in control systems: nutrient dosing based on nutrient dilution equations (method α), sensor-based (method β), and a mixed nutrient dosing method combining the two previous methods (method γ). This research begins by identifying several nutrient dosing methods that can be used in control systems. After that, the dosing methods were tested, and data analysis was carried out. Based on the three methods proposed in this study, method γ has the best results with a mean absolute percentage error (MAPE) of 0.77% and a root mean square error (RMSE) of 4.3, respectively, in relation to the targeted concentration of the nutrient solution. Method β has slightly higher results, with a MAPE of 0.82% and an RMSE of 4.62. Method α has the worst results, with a MAPE of 13.42% and a RMSE of 74.98. However, if the desired target nutrient concentration is less than 300 ppm, method β is the most suitable option compared to the other methods.","PeriodicalId":509812,"journal":{"name":"Jurnal Keteknikan Pertanian","volume":"50 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139166506","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}

Teknologi iradiasi dapat diterapkan untuk mereduksi mikrob pada vanili tujuan ekspor. Tujuan penelitian adalah menguji efektivitas iradiasi gamma terhadap mutu vanili hasil curing serta menentukan dosis iradiasi terbaik dengan mutu masih diterima oleh konsumen. Rancangan percobaan adalah rancangan acak lengkap faktorial dengan tiga ulangan. Faktor pertama dosis iradiasi sebanyak tiga taraf yaitu 10, 15 dan 30 kGy serta tanpa iradiasi (0 kGy) sebagai kontrol. Faktor kedua adalah bahan baku vanili hasil curing sebanyak tiga taraf yaitu vanili curing dengan pengering efek rumah kaca (ERK) tanpa peram lanjut, vanili curing dengan pengering ERK dan peram lanjut empat malam serta vanili curing hasil penjemuran petani. Pemberian iradiasi dilakukan pada vanili setelah penyimpanan selama dua bulan. Pengujian parameter mutu dilakukan sebelum dan sesudah iradiasi pada sampel yang dikemas, meliputi, fisik, kimia, mikrobiologi, dan uji organoleptik. Dosis iradiasi 10 kGy ditemukan efektif untuk mengurangi cemaran mikrobiologi pada vanili tanpa peram dan dengan peram lanjut sesuai batas cemaran SNI, namun pada vanili penjemuran petani dibutuhkan dosis 15 kGy. Dosis iradiasi tidak memberi efek terhadap susut bobot, kadar air dan kadar vanilin sehingga mutu dan aroma masih baik. Iradiasi meningkatkan nilai L* dan chroma namun kesukaan panelis terhadap warna vanili masih bernilai 4 (agak suka) hingga 30 kGy. Pemberian iradiasi meningkatkan kesukaan panelis terhadap aroma dari agak tidak suka (3) sebelum diiradiasi menjadi agak suka (4) setelah diiradiasi.","PeriodicalId":509812,"journal":{"name":"Jurnal Keteknikan Pertanian","volume":"20 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139171299","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}

Penelitian ini bertujuan untuk menguji pengaruh kombinasi pasir dan zeolit (sebagai media evaporasi) terhadap suhu dan RH yang terbentuk pada sistem penyimpanan ZECC dan menentukan kombinasi pasir dan zeolit yang terbaik untuk penyimpanan sayuran segar. ZECC yang dibangun berukuran 100 (P) x 100 (L) x 50 (T) cm. Perlakuan bahan dinding ZECC yang dikaji adalah 100% pasir (Z1), 75% zeolit dan 25% pasir (Z2), 50% zeolit dan 50% pasir (Z3). Jenis komoditas yang digunakan untuk menguji kinerja ZECC adalah tomat dan selada. Parameter mutu yang diukur selama penyimpanan adalah kadar air, tekstur, warna, TPC dan organoleptik. Hasil penelitian didapatkan suhu yang terbentuk di dalam ZECC setelah diberi beban berupa tomat dan selada lebih rendah dan konstan dibandingkan dengan suhu luar sepanjang penyimpanan, demikian juga dengan RH di dalam lebih besar dibandingkan dengan RH luar. Rata-rata suhu didalam dan diluar ZECC masing-masing adalah 23.47°C dan 29.53°C, sedangkan Rata-rata RH ZECC didalam dan diluar masing-masing adalah 98.53% dan 69.04%.
