Mempelajari Aktifitas Lumpur Aktif Pada Limbah Cair Industri Pangan Sebagai Sumber Mikroba Dalam Pengolahan Limbah Cair Industri Pangan Eko Susanto; Eddy Sapto Hartanto
Warta Industri Hasil Pertanian Vol 29, No 01 (2012)
Publisher : Balai Besar Industri Agro

Dalam kegiatan produksi, industri pangan selalu menghasilkan limbah, baik berupa limbah padat, limbah cair maupun gas. Salah satu cara pengolahan limbah cair indutri pangan adalah dengan cara biologi, menggunakan mikroorganisme selektif sesuai dengan karakteristik limbah industri pangan yang diolah. Pada kegiatan ini telah dilakukan penelitian penggunaan beberapa jenis starter yang berasal dari lumpur limbah cair yang bersala dari industri tahu, bihun dan roti. Penelitian ini bertujuan untuk mendapatkan produk starter mikroorganisme siap pakai dengan biaya murah. Penelitian dilakukan dengan menggunakan 3 faktor yakni A,B dan C dimana faktor A adalah jenis limbah cair, yaitu limbah cair industri tahu, limbah cair industri bihun dan limbah cair industri roti. Faktor B adalah jenis starter yang digunakan yakni lumpur aktif/sludge, phenobac dan kontrol. SEdangkan faktor C adalah waktu inkubasi, 0,2m4 dan 6 hari. Hasil penelitian menunjukkan bahwa lumpur aktif dari industri bihun dapat digunakan untuk mengolah limbah industri pangan lainnya. Tingkat penurunan BOD tertinggi adalah perlakuan limbah cair industri tahu dengan menggunakan lumpur aktif industri bihun selama 6 hari dapat menurunkan BOD dari 2667,4 mg/l menjadi 941,2 mg/l (64,71%). Untuk TSS tingkat penurunan tertinggi adalah air limbah bihun penuruan TSS sebesar 83,23%.

(The Prospect of The Use of Activated Carbon in Industry) HG Pohan

Publisher : Balai Besar Industri Agro

Actived carbon is an amorphous or microcrystalline from carbon which have very large surface area,ranging from 300-2000 meter/gr.There are two process of activation,chemical and physical process.The quality of activated carbon depend on their raw material and activation method.Activated carbon are laregely used in multivarious industry i.e.food and beverage,pharmaceutical,waste treatment and chemical industries.

(Catechin and Epicatechin Analysis in Cacao Bean and Cacao products Using Liquid Chromatography Mass Spectrometry) Subagja -; Harmita -; Herman Suryadi; Lukman Junaidi
Warta Industri Hasil Pertanian Vol 26, No 02 (2009)
Publisher : Balai Besar Industri Agro

Cacao beans processing into product may affect active compound contents in the final products, especially catechin and epicatechin. Temperature treatments during cacao processing can induce epimerization reaction of (-)-epicatechin to be (-)-catechin. Therefore, catechin and epicatechin ratio in the samples would be change. The aim of the was to know imfluence during cacao beans processing, especially cathechin and epicatechin concentration. Samples taken during the process were cacao nib, cacao mass, cacao powder, and butter. Analysis of catechin and epicatechin in samples was carried out by liquid chromatography mass spectrometry. Analytical for catechin were using mobile phase A (0.1 %formic acid in deionized water) and mobile phase B (acetonitril-methanol = 50:50) at flow rate of 0.5 ml/min. gradient elution were set at 0 minutes (10%B), 15 minutes (35%B), 20 minutes (40%B), 30 minutes (50% B), 35 minutes (60% B), and 35.1 minutes (105 B). Mass sprectrometer was set at ESI voltage (-) 3500 volt, desolvation temperature 300 oC, nubelizer pressure 50 psi, desolvation gas 10L/min, and fragmentor voltage (-) 160 volt. Results of the research showed that of catechin and cacao nib, cacao mass and cacao powder were 1:21,7; 1:20,0; and respectively. Heat treatments during cacao mass processing sowed a decrease tendency of catechin and epicatechin concentrations.

(Substitution of defatted Soybean Meal For Soybean in Tofu Production) Sri Wuri Handono Wuri Handono; Atih Suryati Herman; Aan Yulistia
Warta Industri Hasil Pertanian Vol 4, No 02 (1987)
Publisher : Balai Besar Industri Agro

Techno-economic study on using deffated soybean meal as a substitute for soybean in tofu production has been conducted. Eight degree of substitution (5, 10, 15, 20, 25, 30, 35 and 40%) were used in making tofu. Substitution of deffated soybean meal for soybean decreased the yield as well as the oraganoleptic properties of tofu. The substitution was acceptable up to the amount of 20%. The study showed that 20% substitution will be profitable if the price of the meal is less than 47% of the soybean price.

(The Use of Organic Acid and Thermal Adequacy on the Canned String Beans) Ngakan Timur Antara; H G. Pohan; Subagja -
Warta Industri Hasil Pertanian Vol 18, No 1-2 (2001)
Publisher : Balai Besar Industri Agro

Research on the canned string beans has been conducted .the formulation used was 1% salt,the organic acid (0.27% citric acid and 0.22% lastic acid ) and types of packaging (timplate and retort pouch) the product were stored for 0,2,4 and weeks the results showed that the result showed that the effect of storage gave the decrease of PH ,protein ,vitamin c and hardness.the microbial contents were relatively unchanged during storage .the process time required for tinplate retort pouch were 0.057 minutes respectively ,which adequate to render to canned string beans (pH< 4.5) microbiologically safe .

(Chemical Handling of Tapioca Waste Water) Endah Djubaedah; Mochamad Noerdin N.k; Sri Harjanto
Warta Industri Hasil Pertanian Vol 11, No 1-2 (1994)
Publisher : Balai Besar Industri Agro

Chemical handling of tapioca waste water using coagulans (Alum and poly ammonium chloride), flocculan (polymer code 161),and areation had been done. The treatment in laboratory scale descreased BOD value from 148.59 mg/1 to 54.315 mg/1;COD value from 251.540 mg/1 to 138.875 mg/1; suspended solid from 31.8 mg/1 to 1.719 mg/1; and soluble solid from 2.87 mg/1 to 0.01 mg/1.these result were in accord with the local standard for waste water.

Ketertelusuran adalah kemampuan dari suatu sistem untuk menelusuri produk dan riwayatnya melalui seluruh atau bagian dari rantai produksi, mulai dari saat pemanenan terhadap ketertelusuran pada produk pangan dan hasil pertanian dalam 10 tahun terakhir ini cenderung meningkat secara signifikan seiring dengan meningkatnya kasus yang berhubungan dengan keamanan pangan dan penyakit langka (seperti penyakit kuku dan mulut, penyakit sapi gila, kontaminasi mikrobiologi pada produk segar, senyawa dioksin pada produk peternakan) serta meningkatnya perhatian dampak pangan hasil rekayasa genetika (GMO) pada rantai pangan manusia dan lingkungan. Implemnebtasi sistem ketertelusuran mempunyai aspek-aspek penying yang berhubungan dengan keamanan pangan, mutu dan labeling produk pangan. Cepatnya perkembangan pada teknologi informasi telah menyebabkan kemungkinan untuk menerapkan sistem ketertelusuran dalam industri pangan. Bagi produsen pangan skala kecil, pengembangan sistem secara kelompok dan sertifikasinya memudahkan dalam mengatasi kendala yang dihadapi pada penerapan sistem ketertelusuran, dengan penguatan kapasitas dalam pemilihan jenis teknologi tepat guna untuk ketertelusuran. Dalam tulisan ini akan dibahas mengenai konsep dan definisi ketertelusuran, keuntungan sistem ketertelusuran bagi industri pangan, pemerintah dan konsumen, implementasi sistem ketertelusuran pada produk pangan dan produk hasil pertanian, serta kendala dan peluang penerapan sistem ketertelusuran.
