Abstract

Regulasi mengenai komoditas beras yang ditetapkan oleh Pemerintah, yaitu Peraturan Menteri Perdagangan No:57/M-DAG/ PER/8/2017 tentang penetapan harga eceran tertinggi (HET) beras dan Peraturan Menteri Pertanian No.:31/Permentan/PP.130/8/2017 tentang standar mutu beras menjadi dasar pelaksanaaan kegiatan identifikasi mutu beras terhadap beras produksi gabungan kelompok tani (Gapoktan) dan kelompok tani (Poktan) selaku Lembaga Usaha Pangan Masyarakat (LUPM) dalam kegiatan Pengembangan Usaha Pangan Masyarakat (PUPM). Kegiatan PUPM tersebut diselenggarakan pemerintah untuk stabilisasi harga dan pasokan beras melalui peran serta Toko Tani Indonesia Center (TTIC) sebagai lembaga distribusi beras kepada masyarakat. Penelitian ini bertujuan mengidentifikasi kelas mutu beras yang dihasilkan LUPM dan mengevaluasi penanganan pascapanen padi di tingkat LUPM. Survey dilakukan terhadap enam responden dari populasi 80 LUPM pemasok beras ke TTIC. Pengumpulan data dilakukan melalui wawancara, observasi di lapangan, dan pengambilan contoh gabah dan beras berdasarkan metode SNI 19-0428-1998. Analisis mutu berdasarkan metode SNI 01-0224-1987 untuk gabah dan SNI 6128:2015 untuk beras giling. Hasil penelitian menunjukkan bahwa dari enam beras yang diproduksi responden, tidak ada yang memenuhi persyaratan kelas mutu sesuai Peraturan Menteri Pertanian No.:31/Permentan/ PP.130/8/2017 karena kadar air yang tinggi, jumlah butir patah dan butir menir yang lebih tinggi, serta persentase beras kepala dan derajat sosoh yang lebih rendah dari persyaratan. Faktor-faktor kritis yang berpengaruh terhadap rendahnya mutu beras LUPM adalah penggunaan varietas padi jenis panjang dan ramping, metode perontokan cara gebot, kadar air gabah kering giling terlalu rendah (11.5-13.0%), ruang penyimpanan gabah lembab (RH udara 79-87%), penyimpanan gabah tanpa menggunakan alas, pengendalian mutu pengeringan dan penggilingan secara subyektif, dan teknologi mesin penggilingan padi yang masih sederhana.  Analysis of rice quality and assurance system implementations in Society of Agrifood Bussiness Development ProgramRegulations on rice applied by the government, namely the Regulation of Minister of Trade No:57/M-DAG/PER/8/2017 about the highest selling price for milled rice, and the Regulation of Minister of Agriculture No:31/Permentan/PP.130/8/2017 about milled rice quality standard, has becoming legal aspects to identification of milled rice quality parameters to the rice produced by farmers group as a Society of Agrifood Bussiness Institution (LUPM) in a Society of Agrifood Bussiness Development (PUPM) program. This program held by the government for stabilization of price and supply of milled rice supported by Center of Indonesian Farmer Store (TTIC) as a distribution institution of milled rice to consumers. Te objectives of this study are to identify the quality of milled rice produced by LUPM and to evaluate the paddy postharvest handling in the LUPM. Survey was conducted on six respondents from total of 80 LUPMs rice supplier population. Data collecting was conducted through interviews, field observations, and sampling of rice and milled rice based on SNI 19-0428-1998 for solid sampling instructions. Laboratory quality analysis was conducted based on the method in SNI 01-0224-1987 for rice and SNI 6128:2015 for milled rice.It was oberved that the six milled rice samples produced by the respondents were not qualified to the quality standard in the Regulation of the Minister of Agriculture No.:31/Permentan/PP.130/8/2017 because of higher moisture content, higher broken rice and small broken rice, and lower head rice, and lower milling degree compared to the requirements. Critical factors influenced to the milled rice quality were the used of long grain paddy variety, manual threshing, too low moisture content of rice (11.5-13.0% MC), high relative humidity of rice storage facility (air RH 79-87%), lack of pallets in rice bags storage system, subjectivity of operators to control the rice quality during drying and milling process, and the use of milling machines with old technology.

Abstract

Ozone can be used as an alternative to control mold and aflatoxins in grains that is more eco-friendly because it does not leave residues that are harmful for humans, animals and environment. The use of ozone was quite effective in reducing mold and aflatoxin in grains such as barley, whole wheat, corn and rice. In Indonesia, ozone was limited used for sterilization of fruit and vegetable. Therefore, the comprehensive review on the potential of ozone in grains is needed, especially on the priority commodities of agricultural development in Indonesia, such as rice and corn. The objective of this review was to examine the opportunities of ozone to reduce Aspergillus flavus and aflatoxin in grains, so that it can improve its quality and shelf life. Many studies showed that the use of ozone reduced Aspergillus flavus and aflatoxin in grains by 50-90%.Keywords: Grains, Aspergillus flavus, aflatoxin, ozone AbstrakOzon dapat digunakan sebagai salah satu alternatif pengendalian cendawan dan aflatoksin pada biji-bijian yang lebih ramah lingkungan karena tidak meninggalkan residu yang berbahaya bagi manusia, hewan, maupun lingkungan. Penggunaan ozon cukup efektif mengurangi kontaminasi cendawan dan aflatoksin pada bijibijian seperti barley, biji gandum, jagung, dan beras. Di Indonesia, ozon digunakan secara terbatas untuk proses pencucian beberapa jenis buah dan sayuran. Oleh karena itu diperlukan telaah lebih lanjut mengenai potensi penggunaan ozon pada biji-bijian terutama komoditas strategis yang menjadi prioritas dalam pembangunan pertanian di Indonesia seperti padi dan jagung. Tujuan dari tulisan ini adalah untuk menelaah peluang penggunaan ozon dalam mengurangi kontaminasi Aspergillus flavus dan cemaran aflatoksin pada produk biji-bijian, sehingga diharapkan dapat memperbaiki kualitas dan meningkatkan umur simpan produk. Hasil penelitian menunjukkan penggunaan ozon dapat menurunkan cemaran A. flavus dan aflatoksin pada biji-bijian sampai 50-90%.Kata kunci: Biji-bijian, Aspergillus flavus, aflatoksin, ozon

Abstract

Pulping and fermentation of coffee cherry determine the quality of green beans and coffee flavors. Delay in pulping will cause the slime stick to the hull skin hence decreasing the bean quality and flavor. The objective of this study was to examine the effect of soaking before pulping and fermentation time to the color of coffee hull skin and the cup quality. The research was carried out at the experimental station of Indonesian Coffee and Cocoa Research Institute in Malang Regency (ICCRI) and ICCRI laboratory in Jember Regency from July 2018 to January 2019. Experiments used factorial completely randomized design. The first factor was cherry soaking duration (0, 24, 48, and 72 hours) and the second factor was fermentation duration (0, 24, and 48 hours) and then combined into 12 treatments, with three replications. Ten kilograms of coffee cherries were soaked prior to pulping then fermented in a plastic bag and added with Lactobacillus casei 2,5 x 107 cfu/ml as starter.  Parameters observed were color of hull skin (L value, a*, dan b*) and the cup quality.  The results showed that soaking the cherry decreased the green beans quality which is indicated by less brightness (L), high a* value, and decreasing b* value of hull skin color. While the fermentation treatment can increase the value of L, decrease the a* value, and increase the b* value. The interaction of treatment of soaking and fermentation time significantly affected the lightnessl a* and b* value. Soaking and fermentation treatments did not significantly affect to the flavor, salt/acid, balance, and total score of coffee flavor. Soaking is not recommended for more than 48 hours and fermentation should be carried out 48 hours.

Abstract

The processing of coffee can be classified into 3 types namely: dry, semi-wet and wet processing. And then, roasting is the process of forming the taste and aroma of coffee. The study was conducted at Pakuwon Experimental Station, Coffee and Cacao Processing Units, and Integrated Laboratory of Balittri, and TTPHP Laboratory of IPB Bogor, from July until October 2019. The study aimed to investigate (1) the effect of processing methods on physical quality characters of green beans, and (2) the effect of processing methods and roasting temperatures on chemical characters of coffee roasted and organoleptic characters of coffee brewed. The completely randomized design in factorial 2 factors and 3 replications was used in this study. The first factor were 3 type of processing methods (dry, semi-wet, and wet), and the second factor were 2 level of roasting temperatures (180oC and 210oC). The variables observed in the green beans were physical quality characters, while in roasted coffee were water content, caffeine content, and antioxidant activity, and in brewed coffee were organoleptic characters. Result showed that the best green beans was produced from a wet processing method with a minimum total defect value of 21.33 (quality 2). Roasting temperature has a very significant effect (p<0.01) on water content and antioxidant activity, while caffeine content is not significantly affected. Based on the results of cupping test, the best brewed coffee (final score >80.00) was obtained from the treatments of a dry, semi-wet and wet processing method with a roasting temperature of 210°C.

Abstract

Yeasts and bacteria are two of common biocontrol agents to control mycotoxigenic fungi, meanwhile the mangosteen rind exract has xanthone and gartanin compounds for antioxidant, antiproliferation, antiinflammation, antimicrobial, and anticancer. The objectives of this research are to test the effects of yeasts, acetic acid bacteria (AAB), and mangosteen rind extract on the aflatoxigenic Aspergillus flavus growth and aflatoxin production in unfermented cocoa beans. Four yeast isolates, i.e. Issatchenkia orientalis (Io) BIO 211291, 286 and 288, and Endomyces fibuliger (Ef) BIO 132219; one bacteria isolate of Acetobacter aceti (Aa) FNCC0016; and mangosteen rind extract (MRE) were tested for their capabilities in inhibiting an aflatoxigenic A. flavus (Af) BIO 3361/747 growth using the well method (in vitro). Two yeast (Io BIO 211291 and 288) were combined with Aa and MRE in cocoa beans (in vivo). Aflatoxin production was analyzed using Thin Layer Chromathography (TLC). The result showed that interaction of Io BIO 211291 and 288, and Ef BIO 132219 on aflatoxigenic Af were interaction with inhibition zone ≥ 2 mm (type D), while the interaction type of Io BIO 211286 on Af were mutual intermingling growth, where both fungi grew into each other without any macroscopic sign of interaction (type A). The best treatment in agar media (in vitro) was Io BIO 211288 + Aa on Potato Dextrose Agar + 12 g/l MRE. The highest Io population was 5.88 log cfu/g on cocoa beans inoculated by Io BIO 211291 + MRE in 1 day after inoculation, while the highest A. aceti population was 4.74 log cfu/g on cocoa beans with Io BIO 211291 + BIO 211288 + Aa  in 3 days after inoculation. Two best treatments were Io BIO 211288 + Aa + MRE and Io BIO 211291 + BIO 211288 + Aa + MRE, because there were no A. flavus population since 3 until 11 days after inoculation. Aflatoxin in all samples treatment was lower than limit detection B1 (< 2.20 ppb),  B2 (< 3.50 ppb), (G1 < 0.54 ppb), dan (G2 < 1.00 ppb).

Abstract

Abstrak Biji ginkgo harus dibuka untuk diambil dan dimanfaatkan isinya yang lunak. Untuk membuka pelindung daging biji yang keras, orientasi biji harus diketahui, karena biji lebih mudah terbuka pada ujungnya, sedangkan bagian pangkalnya cenderung tetap menyatu. Bila orientasi tidak tepat, maka akan dibutuhkan gaya tekan yang jauh lebih besar untuk membukanya, sehingga seringkali daging biji ikut rusak terkena gaya tekan yang berlebihan. Program pengolahan citra dibuat dan digunakan untuk melakukan deteksi bagian ujung dari biji ginkgo. Hasil deteksi bagian ujung biji menggunakan algoritma berdasarkan analisis morfologi masing-masing 100% untuk Kinbei, 85% untuk Kyujyu, dan 65% untuk Tokuro. Operasi morfologi dilakukan untuk memperbaiki bentuk biji pada citra biner sehingga kemampuan deteksi ujung biji dapat ditingkatkan. Hasil deteksi bagian ujung biji setelah operasi perbaikan bentuk dilakukan masing-masing meningkat menjadi 100% untuk Kyujyu dan 85% untuk Tokuro, sedangkan Kinbei tidak terpengaruh, tetap 100%. Kata Kunci: biji ginkgo, deteksi ujung biji, pengolahan citra, morfologi analisis Abstract Ginkgo nut has to be cracked to obtain its soft and usefull meat for utilization.
