ANALISIS PERBANDINGAN EMISI DARI PERBEDAAN METODE PENGGORENGAN KERIPIK PISANG DI LAMPUNG DENGAN METODE LCA (LIFE CYCLE ASSESSMENT)
Get PDFBanana chip processing in Lampung province uses two different frying methods, namely conventional frying and vacuum frying. The objective of this study was to compare the number of impact emissions generated from the banana chip production process in banana chip agro-industries in Lampung. This research was conducted based on the Life Cycle Assessment (LCA) method to assess the environmental impact emissions from the banana chip industry in Lampung, focusing on the impacts of Global Warming Potential (GWP), Acidification Potential (AP) and Eutrophication Potential (EP) with a function unit of 250 g/pack. Analysis using SimaPro 9.4.2 software. Analysis using the CML-IA Baseline method shows that the banana chip industry has a significant environmental impact with the largest impact by the industry, where the conventional frying method produces a GWP impact of 1.16 kg CO2 eq/package, EP 2.08E-2 kg PO4 eq/package and AP 3.6E-3 kg SO2 eq/package, while in the vacuum frying method, the GWP is 6.3E-1 kg CO2 eq/package, AP 2.3E-3 kg SO2 eq/package and EP 6,1E-3 kg PO4 eq/package. The calculated normalization data shows that the total impact of producing banana chips per package in conventional frying is 1.9E-12 person equivalent/package with the frying stage contributing 85.45% and in vacuum frying is 6.7E-13 person equivalent/package with the frying stage contributing 77.70%. The resulting emission impact value shows that the emission impact of conventional frying is higher than the emission impact of vacuum frying. However, an economic and social assessment of both frying methods needs to be done to see the sustainability index of both.

PIROLISIS SABUN LOGAM DARI ASAM OLEAT UNTUK PRODUKSI BIOHIDROKARBON HIJAU
Get PDFMetal soap pyrolysis is an attractive route for green gasoline fuel production because it is a straightforward process with no hydrogen supply needed and is operated under a pressure atmosphere. Pyrolysis of soap made from oleic acid is carried out via the catalytic route in a Py-GC reactor. Bivalent metals such as Zn, are evaluated as catalysts in pyrolysis. The preparation of a mixture of oleic acid: NaOH: Zn metal was studied at a concentration of 1:1:1. Thermal stability analysis of pyrolysis was studied at a temperature of 250oC with a heating rate of 10, 20, 40oC/min. This research aimed to figure out the characteristics of the relationship between raw materials, metal soap, and the bio-hydrocarbon products produced. Experimental results show that Zn metal can supply good temperature stability during the pyrolysis heat degradation process. Zn metal also can act as a catalyst, helping the decarboxylation reaction of oleic acid to become short-chain bio-hydrocarbons. The yield of short-chain bio-hydrocarbons C9-C18 was 0.04-7.33%w/w, meanwhile, long-chain bio-hydrocarbons reached 48.07%w/w. The presence of oxygenate compounds is due to the low quality of the raw materials. A decrease in the quality of raw materials can be caused by poor handling and storage of oleic acid as evaluated by large saponification, acid, and peroxide numbers.

PEMETAAN JEJARING SOSIAL TECHNOPRENEUR AGROINDUSTRI DALAM TAHAP AWAL PROSES KEWIRAUSAHAAN
Get PDFA technopreneur\u27s social network is a key factor in the early stages of the entrepreneurial process which includes the stages of searching for ideas, acquiring resources, and gaining legitimacy for the development of his business. It is hoped that a technopreneur\u27s ability to create, manage and maintain social networks can improve the performance of the business he starts. This research aimed to map the social network of technopreneurs in the early stages of their entrepreneurial process and analyze their evolution in the three initial stages. The technopreneur social networks studied were betweenness, centrality, density and diversity. Networks are built using an ego network approach. The egos used were eight new businesses that are members of a business incubator with the criteria of food and non-food agro-industry, business unit age 2 – 5 years, in wall which means having an office in the incubator and out wall which means having an office outside the incubator. The network was analyzed using software. The results of the analysis show that technopreneurs who are on the in wall have a denser network than those on the out wall due to the large number of actors who come from the incubator network. The parameter values of betweenness, centrality, diversity and density change at each stage of the entrepreneurial process. Technopreneurs need diversity and betweenness in the idea search phase to increase the flow of information and ideas. Technopreneurs need centrality and density in the resource acquisition phase to increase resource access. Centrality and density are needed in the legitimacy phase to increase a technopreneur\u27s reputation.

EFFECT OF GINGER OLEORESIN CONCENTRATION ON THE ENCAPSULATION PROCESS USING IONIC GELATION
Get PDFThe primary active components in ginger oleoresin are gingerol and shogaol, with gingerol exhibiting significant pharmacological activities such as anti-inflammatory, antioxidant, and analgesic effects. However, gingerol is heat-sensitive and degrades at elevated temperatures, limiting its functional efficacy when consumed. To overcome this limitation, encapsulation of ginger oleoresin was performed to enhance its physical and functional properties and improve its bioavailability. This study utilized the ionotropic gelation method to encapsulate ginger oleoresin, resulting in the formation of beads. Alginate was employed as the encapsulation matrix. The dried beads were characterized using FTIR, SEM, disintegration tests, and encapsulation efficiency was assessed via UV-Vis spectrophotometry. Results demonstrated that alginate beads containing ginger oleoresin could be successfully synthesized using the ionotropic gelation technique, with alginate as the polymer and CaCl2 as the cross-linking agent. Ginger oleoresin concentrations of 0.9%, 0.7%, 0.5%, and 0.3% were tested. The highest encapsulation efficiency, 72.48%, was obtained with a ginger oleoresin concentration of 0.7%. Surface morphology analysis revealed that the alginate beads exhibited a rough, porous texture with visible folds. Furthermore, the dry beads disintegrated within 30 minutes.

PENGARUH PENGGUNAAN TEKNOLOGI CRF (Controlled Release Fertilizer) PADA UJI EFEKTIVITAS TANAMAN BAWANG MERAH
Get PDFShallot (Allium cepa L. var ascalonicum) is one of the leading vegetable commodities that is widely used and has high economic value. National shallot productivity continues to decline from year to year, so it is necessary to increase shallot production both in quantity and quality. One way that can be done is to apply effective efforts in the cultivation system such as the use of effective and efficient fertilizer technology. The purpose of this research was to determine the effect of using Controlled Release Fertilizer (CRF) technology on the effectiveness test of the shallot variety SS Sakato which was carried out on a 4200 m2 plot of land in Kuningan, West Java. The results show that the use of CRF technology can increase growth (plant height), and the number of tillers, and increase shallot productivity. The increase in plant height at 30 HST increased by an average of 50% for all treatments and then slowed down to 20% in the second month. Regarding the number of tillers, the use of CRF technology can increase by about 38% when compared to controlled plots. Against the weight of the harvest, it can increase by 7-22% higher than the use of NPK fertilizer (comparison). The quality of the shallots produced also shows better with larger tuber sizes and brighter colours.
