Abstract

Food coloring and flavoring from pandan leaves (Pandanus amaryllifolius) are natural dyes that can be used as an alternate to synthetic dyes. Meanwhile there is a potential to establish factory to support it as well as raw material availability. The purpose of this study was to conduct a pre-feasibility study of establishing a natural pandan preparations industry. The scope of this study includes market and marketing analysis, technical and technological analysis, management and organizational analysis, and financial analysis. The target market is the cake and bread industry, hotels, restaurants, and cafes in West Java. This industry is planned to be established in Tasikmalaya City, West Java with a production capacity around 44 ton/year. The results of the pre-feasibility study are that the industry is feasible with a Net Present Value of Rp 3.358.666.480; an Internal Rate of Return of 27.408%, a Net Benefit Cost Ratio 2.652; and 4.05 years payback period. Furthermore, based in the sensitivity analysis indicated that the decrease in selling price is more sensitive compared to the increase in operating costs and decrease in production capacity, and the increase in operating costs is more sensitive when compared to a decrease in production capacity. A decrease in selling price of 15% or an increase in operating costs of 20% has made the pandan preparation industry not feasible. Keywords: coloring, flavoring, pandan leave, pre-feasibility study

Abstract

Bambu muda atau rebung memiliki sumber selulosa dan berpotensi untuk produksi bioetanol. Rebung juga memiliki kandungan lignin yang rendah yaitu 0,89%, sehingga memungkinkan untuk tidak dilakukan proses pre-treatment. Rebung bambu merupakan salah satu bahan yang berpotensi untuk produksi bioetanol mengingat laju produktivitas yang tinggi yaitu 8.124 kg/ha/tahun. Tujuan dari penelitian ini adalah menganalisis data produksi bioetanol dari rebung dengan teknik SSF menggunakan konsorsium mikroba Trichoderma reesei dan Saccharomyces cerevisiae. Mikroba T. reesei digunakan untuk menghasilkan enzim selulase yang menghidrolisis selulosa menjadi gula sederhana, sedangkan S. cerevisiae digunakan untuk memproduksi bioetanol dari gula yang dihasilkan sebelumnya. Sintesis bioetanol terdiri dari dua tahap utama yaitu hidrolisis dan fermentasi. Pada penelitian sebelumnya, proses hidrolisis dan fermentasi dilakukan secara terpisah menggunakan metode SHF (Separated Hydrolysis Fermentation), sedangkan pada penelitian ini dilakukan dengan menggunakan metode SSF (Simultaneous Saccharification and Fermentation) yang diharapkan menghasilkan efisiensi substrat, Yp/s, dan laju produktivitas bioetanol yang lebih tinggi dibandingkan metode SHF. Penelitian ini dilakukan menggunakan aerasi 1 vvm dan agitasi 125 rpm selama 72 jam.  Hasil penelitian menunjukkan bahwa produksi  bioetanol tertinggi di waktu 72  jam sebesar 6,94 g/L dengan laju produktivitas bioetanol  0,08 g/L/h dan  rendemen produk (Yp/s) 0,19 g bioetanol/g substrat. Hasil penelitian ini menunjukkan bahwa rebung merupakan media yang layak untuk produksi bioetanol. Rebung memiliki kandungan selulosa yang potensial sebagai substrat untuk T. reesei dan terbukti menghasilkan bioetanol yang lebih tinggi dibandingkan teknik SHF dengan bambu pada penelitian sebelumnya.

Abstract

Abstract The initial step in planning an agro-industry establishment is determining the type of superior commodities and the right industrial location. Identification of superior commodities and determination of location in coastal areas are still limited, even though the area has complex environmental conditions. This study aimed to identify superior commodities and determine potential locations for agro-industry. The research was conducted in Bekasi Regency, West Java, Indonesia. The methods used to identify advantages were Location Quotient and Shift Share. Determining industrial locations used the Geographic Information System (GIS) with the pairwise comparison method. The study results showed that the three main superior commodities in Bekasi Regency were seaweed, milkfish, and shellfish. The agro-industry potential location based on the analysis of industrial requirement parameters and by the Bekasi Regency Spatial Plan (SP) for the development of industrial areas was Cabangbungin District. The location meets the requirements in terms of proximity to energy sources, water sources, business centers/markets, accessibility to main roads, and the place's elevation and slope. The use of land cover with a potential land area by the location is 985.97 Ha. This study result can be used as a reference for policy considerations of decision-making systems for other coastal areas.Keywords: agro-industry, Bekasi Regency, GIS, leading commodities, potential location AbstrakPenentuan jenis bahan baku unggulan dan lokasi industri yang tepat merupakan langkah awal dalam perencanaan pendirian agroindustri.

Abstract

AbstractCultivation of Spirulina platensis in an abundant available and inexpensive medium such as palm oil mill effluent (POME) will produce biomass and valuable active materials at competitive price.  Utilization of POME  will also reduce pollution level and support cleaned production.  The objectives of this research were to determine the dilution rate of  S. platensis and the reduction rate of pollution level of POME on continuous photobioreactor. Preliminary research was conducted by growing S. platensis on POME medium with various concentration, namely 25%, 50%, 75%, and 90% POME on batch system. The experiment was conducted in 1.2 L capacity continous photobioreactor using medium containing a mixture of POME and synthetic medium. Feeding rate was set up at 0.05 mL/5 sec. (dilution rate of  0.03 hr -1), 0,05 mL/10 sec. (dilution rate of  0.015 hr -1), and 0.05 mL/15 sec. (dilution rate of 0.01 hr -1). For optimum dilution rate, the experiment was scaled up eight times using 10 L capacity continous photobioreactor. The results showed that optimum growth rate of S. platensis (µmax) = 0.233, was achieved using medium consisting of 90% POME and 10% synthetic medium after two weeks. Dilution rate of 0.015 hr -1 on photobioreactor was the optimum dilution rate for growth of S. platensis as well as for decreasing polution level of POME. The result of the eight-times scale up photobioreactor using flow rate of 0.4 mL/10 sec and dilution rate of 0.015 hr -1 showed that the growth of S. platensis was relatively constant as reflected by the OD value of the suspension culture and the concentration of cellular biomass. At the optimum condition, production of S. platensis biomass was 0.267g/L and pollution level was decrease 24%. The rate of outflow also resulted the constant decrease of polution level based on total carbon (TC), total dissolve solid (TDS), dissolve oxygen (DO), BOD, and COD parameters indicating that  continuous photobioreactor was running at steady state.Abstrak Kultivasi S. platensis dalam media yang tersedia me-limpah dan murah seperti limbah cair pabrik kelapa sawit (LC-PKS) akan menghasilkan biomassa dan bahan aktif bernilai ekonomi tinggi dengan harga kompetitif. Pemanfaatan  LC-PKS  juga  akan  mengurangi  dampak pen-cemaran lingkungan dan membantu menciptakan sistem produksi bersih. Penelitian ini bertujuan menetapkan laju dilusi optimum per-tumbuhan S. platensis dan laju penurunan tingkat cemaran LC-PKS pada fotobioreaktor sistem kontinyu. Untuk mengukur laju alir sistem kontinyu, pertama S. platensis ditumbuhkan pada media LC-PKS 25%, 50%, 75%, dan 90% dengan sistem batch.  Pertum-buhan S. platensis  pada fotobioreaktor sistem kontinyu kapasitas 1,2 L dirancang dengan variasi laju alir umpan berupa LC-PKS yang dicampur media sintetik pada konsentrasi optimum. Variasi laju alir pengumpanan diatur pada variasi 0.05 mL/5 detik (laju dilusi 0,03 jam-1), 0,05 mL /10 detik (laju dilusi 0,015 jam -1), dan 0,05 mL/15 detik (laju dilusi 0,01 jam-1). Pada laju alir optimum, skala percobaan diperbesar delapan kali menggunakan foto-bioreaktor berkapasitas 10 L. Hasil penelitian menunjukkan bahwa laju pertumbuhan maksimum (µ maks) adalah 0,233 jam-1 yang diperoleh dengan campuran media LC-PKS 90% dan media sintetik 10%  selama dua minggu. Fotobioreaktor dengan laju dilusi 0,015 jam-1 merupakan laju alir umpan yang optimum untuk pertumbuhan S. platensis serta menghasilkan penurunan tingkat cemaran LC-PKS yang optimum.  Hasil penelitian dengan perbesaran skala delapan kali menggunakan laju alir pengumpan 0,4 mL/10 detik  (laju dilusi 0,015 jam-1)  menunjukkan bahwa pertumbuhan S. platensis relatif konstan. Produksi biomassa sel rata-rata sebesar 0,267g/L dan kadar cemaran limbah rata-rata menurun sebesar 24%. Laju alir keluar (outflow) juga menghasilkan kadar cemaran limbah yang konstan ber-dasarkan parameter total karbon (TC), total dissolve solid (TDS), dissolve oxygen (DO), BOD, dan COD yang menunjukkan bahwa sistem fotobioreaktor kontinyu ini berjalan dengan baik.

Abstract

Summary Gamma linolenic acid (GLA) is a polyunsaturated fatty acid having high economic value as healthy oil. Research at laboratory scale showed that Absidia corymbifera and Rhizopus sp. fungi have the ability to increase unsaturation level of crude palm oil (CPO) and GLA formation through enzymatic bioconversion.  Stability of desatu-rase enzyme, especially ∆6 and ∆12 having significant role in this process could be enhanced by applying immobilization technique. The current research objective was to determine optimum process of CPO bio-conversion using immobilized desaturase enzyme using continuous system at semipilot scale to produce CPO containing GLA.  Crude  desaturase enzyme of A. corymbifera biomass was immobilized with zeolite particles and used for optimization of CPO bioconversion in continuous system at semipilot scale (15,000 mL per day). Optimization of bio-conversion conditions included flow rate of substrate, size of zeolite for immobilization, and enzyme stability during process.  The result showed that desaturase immobilized in small size particles of zeolite (1-3 mm) gave higher increase unsaturation level with average desaturase activity of 7.84 U, compared to that immobilized in larger zeolite  particles (8-10 mm), which reached average desaturase activity of 4.67 U.  However, the use of small zeolite particles often caused plugging substrate flow. The activity of immobilized desaturase in continuous  system was stable for 9-18 hours. Optimum flow rate of substrate using small zeolite particles (1-3 mm) was  850 mL/min, while that of using larger zeolite particles (8-10 mm) was 875 mL/min.  The bioconversion of CPO at optimum condition yielding 1.58% (w/w) GLA from initial concentration of linolenic acid 0.29%. RingkasanAsam γ-linolenat (GLA) merupakan asam lemak takjenuh majemuk yang memiliki nilai ekonomi tinggi sebagai minyak kesehatan. Penelitian pada skala laboratorium me-nunjukkan bahwa Absidia corymbifera dan Rhizopus sp. memiliki kemampuan untuk me-ningkatkan ketidak-jenuhan minyak sawit mentah (CPO) dan menghasilkan GLA melalui biokonversi enzimatis. Stabilitas enzim desaturase, khususnya ∆6 dan ∆12yang berperan pada proses ini dapat ditingkatkan antara lain melalui teknik amobilisasi. Penelitian lanjutan ini bertujuan menetapkan kondisi optimum biokonversi CPO untuk menghasilkan minyak yang kaya akan asam lemak takjenuh majemuk, khususnya GLA menggunakan enzim desaturase amobil sistem kontinu pada skala semipilot.  Ekstrak kasar enzim desaturase asal biomassa fungi             A. corymbifera diamobilisasi dengan butiran zeolit dan selanjutnya digunakan untuk optimasi proses biokonversi secara kontinu pada skala semipilot (15.000 mL per hari). Optimasi proses kontinu meliputi laju alir substrat, ukuran butiran zeolit, dan stabilitas enzim selama proses. Hasil penelitian menun-jukkan bahwa desaturase yang diamobilisasi pada zeolit berukuran kecil (1-3 mm) memberikan peningkatan ketidakjenuhan yang lebih tinggi dengan aktivitas rata-rata 7,84 U, dibandingkan dengan yang diamobilisasi pada zeolit berukuran besar (8-10 mm) dengan aktivitas rata-rata 4,67 U. Namun, penggunaan zeolit berukuran kecil sering menimbulkan sumbatan aliran substrat. Aktivitas desaturase amobil pada proses kontinu dapat bertahan selama 9-18 jam. Laju alir optimum substrat pada penggunaan zeolit berukuran kecil (1-3 mm) adalah 850 mL/menit, sedangkan pada penggunaan zeolit besar (8-10 mm) adalah 875 mL/menit. Biokonversi CPO pada kondisi optimum menghasilkan GLA 1,58% (b/b) dari kandungan asam linolenat awal 0,29%tration of linolenic acid 0.29%.

Abstract

North Sumatra is the largest producer of incense (benzoin) in Indonesia and the world. There are 3 varieties of incense that have the potential to be developed. Indonesia has exported incense to Singapore, Malaysia, and China. Incense is exported in the form of raw materials, so the added value is minimal. In order to increase the added value of incense, it can be produced into incense extract. So far, extraction methods have been carried out using conventional methods, including maceration, boiling with water, and distillation with water vapor. The potential of incense has not been fully utilized, especially from its extraction method, so it still needs to be developed. This article aims to review and identify the chemical components of frankincense (Styrax benzoin) and its extraction methods. In addition, the prospects for product development from frankincense are also discussed. Incense extraction with Ultrasonification Assistant Extraction (UAE) is expected to increase the efficiency of the extraction process. The use of solvents and low temperatures, as well as a short extraction time, can maintain the quality of the incense extract. Incense extract can be applied as raw material for perfumes, pharmaceuticals, medicines, and nano applications such as anticancer and antibiofilm. The incense consists of some active ingredients such as cinnamic acid, benzoic acid esters (such as coniferyl cinnamate and cinnamyl), pinoresinol, -caumary benzoate, benzoic acid esters, and triterpenes. These active ingredients are applied as antibacterial and antioxidants. This literature review provides an overview of the characteristics of active ingredients in incense to expand its applications. Incense extract can be applied as a food additive, pharmaceutical, and health ingredient.

Abstract

Carrageenan, a natural sulfated polysaccharide extracted from red seaweed, has gained significant attention in the development of drug delivery systems, particularly as a capsule-forming material. With its biodegradable, biocompatible, and gel-forming properties, carrageenan offers great potential as a plant-based alternative to animal-derived gelatin. This review evaluates the potential of carrageenan, especially iota-carrageenan, in the production of soft capsules as a gelatin substitute, and compares the characteristics of carrageenan-based hard and soft capsules. Soft capsules are generally formulated with iota-carrageenan and plasticizers such as glycerol to achieve optimal flexibility, while hard capsules utilize kappa-carrageenan due to its stronger gel texture. Structural modifications, including depolymerization and polymer blending, have been reported to improve viscosity, elasticity, and disintegration time of carrageenan capsules. Nevertheless, limitations remain, such as high viscosity and slower disintegration compared to gelatin-based capsules. Therefore, formulation optimization and advanced extraction techniques are essential to enhance carrageenan capsule performance. Future research should emphasize cost-effective and high-purity extraction methods, engineered depolymerization processes, and the modification of kappa-carrageenan to exhibit iota-like flexibility. These strategies are expected to advance the feasibility of tropical seaweed-derived carrageenan as a sustainable and halal-compliant material for pharmaceutical capsule applications.

Abstract

The demand for halal products in the Islamic context continues to be high, requiring adherence to halal and haram laws in consuming food and beverages. However, individuals face the challenge of distinguishing between haram meat and permissible halal meat. This study aims to answer these challenges by designing an expert system application within the ERP framework to increase the usability functionality of the system that can differentiate between beef, pork, or a mixture of both based on the physical characteristics of the meat. The aim is to determine halal products permissible for consumption by Muslims. The research methodology includes a data collection process that involves taking 30 meat samples from various sources, and the criteria used to classify the meat will be determined based on an analysis of the physical characteristics of the meat. System administrators use expert systems to ensure proper treatment of meat during administration processes, including separating halal beef from pork and implementing different inventory procedures. The Certainty Factor (CF) inference engine deals with uncertainty even though the expert system's accuracy level is relatively good with several rules. However, these results must be studied further because the plan relies on expert opinion. Therefore, it is necessary to set the correct CF value for accurate height classification. The CF inference engine facilitates reasoned conclusions in meat classification. Functional testing confirms the smooth running of the system, validating its reliability and performance. In addition, the expert system accuracy assessment produces a commendable accuracy rate of 90%. In addition, the expert system works powerfully on various meat samples, accurately classifying meat types with high precision. This study explicitly highlights the expert system's design for meat classification in determining halal products by using the Expert System Certainty Factor. In conclusion, this expert system provides an efficient and reliable approach to classifying meat and supports the production and consumption of Halal products according to Islamic principles.
