Abstract

Limbah kulit kopi hasil produksi Gapoktan belum dimanfaatkan secara optimal, hanya digunakan sebagai pupuk padat tanpa dilakukan pengolahan atau hanya dibuang ke lahan kopi. Limbah kulit kopi  memiliki kandungan nutrisi yang cukup baik untuk diproses menjadi produk yang memiliki nilai tambah tinggi jika dilakukan dengan fermentasi. Tujuan kegiatan adalah memberdayakan gabungan kelompok tani untuk: meningkatkan pengetahuan dan keterampilan pengolahan limbah kulit kopi dengan bahan baku lain menjadi pupuk cair organic.  Metode pelaksanaan kegiatan dengan teknik penyuluhan dan demontrasi cara pengolahan limbah kulit kopi menjadi pupuk organic cair. Hasil kegiatan adalah anggota kelompok tani memahami pentingnya melakukan pengolahan limbah kulit kopi dengan bahan baku yang tersedia menghasilkan pupuk cair dan maggot.  Kedua produk tersebut dapat mengefisienkan pengeluaran pupuk untuk budidaya kopi dan pakan ikan.

Abstract

Post-harvest Robusta coffee conducted by local farmers in West Lampung consisted of two post-harvest processes: dry processing (natural, honey) and wet processing (full wash). The study aimed to identify the post-harvest process stages, the value of quality defects and to characterize the chemical composition (chlorogenic acid, caffeine) of coffee beans from different post-harvest processes produced by Gapoktan Triguna Tribudi Syukur, West Lampung. The research used survey and interview methods equipped with laboratory analysis. The research sample was determined by purposive sampling, a coffee producer (Gapoktan Triguna) who have been fostering coffee in West Lampung for 35 years. Coffee quality analysis refered to SNI 01-2907-2020. The results showed that the post-harvest process carried out by Gapoktan Triguna on honey, natural and full wash processing produced premium quality of of coffee beans (1-2 quality) with the highest number of quality defects produced were broken beans. The roasting process with semi-mechanical and mechanical machines with natural processing produced high chlorogenic acid content (>3%) and the caffeine content according to the SNI caffeine content (2%). Keywords: caffeine, chlorogenic acid, defects, post-harvest, Robusta

Abstract

Tungkal Composite Jambi Liberika Coffee is one of the top qualities of Indonesian coffees that has received a geographic indication certificate (IGs). With its limited production and high prices, currently Tungkal Jambi Liberika coffee is one of the coffees that is prone to being counterfeited. The counterfeiting of Tungkal Jambi Liberika coffee is increasingly difficult to identify, especially in the form of ground roasted coffee. This study evaluated the potential application of UV spectroscopy technology to classify Tungkal Jambi Liberika coffee (with geographic indications) and normal Probolinggo Liberika coffee (non- geographic indications). A total of 120 samples for each Liberika coffee were prepared weighing 1 gram for each sample. Spectra measurements were carried out in the form of a coffee solution. Spectral data were taken using a UV-visible spectrometer with a wavelength interval of 200-400 nm (Genesys™ 10S UV-Vis, Thermo Scientific, USA). By using the average transformed spectra in the 250-350 nm interval, the differences between the two types of Liberika coffee can be clearly seen, especially at some wavelength peaks, namely 270 nm, 300 nm, 315 nm and 346 nm. The classification accuracy obtained for the SIMCA classification is 100% for both Tungkal Jambi Liberika and Probolinggo Liberika coffee. Keywords:   authentication, classification accuracy, Tungkal Jambi Liberika coffee, SIMCA, UV Spectroscopy

Abstract

In this research, the feasibility of using NIR spectroscopy coupled with forward interval partial least squares (FiPLS) regression for nondestructive soluble solids content (SSC) determination in Pondoh snake fruit was investigated. Spectra of snake fruit were acquired using a VIS-NIR USB4000 portable spectrometer in absorbance mode. The SSC was measured using a digital refractometer.  The calibration and validation models were developed using the FiPLS regression using original spectra. The result showed that the optimal combinations of 7 spectral intervals among 11 intervals which selected by FiPLS yielded good results (RMSEC = 0.854783%, rc= 0.96, RMSECV = 0.899828%, rv = 0.95).  Keywords: soluble solids content, absorbance mode, nondestructive method, snake fruit, FiPLS regression, NIR spectroscopy

Abstract

The objectives of this research was to evaluate the feasibility of using NIR spectroscopy and interval partial least squares (iPLS) regression for nondestructive soluble solids content (SSC) determination in snake fruit. Spectra of snake fruit were acquired using a VIS-NIR USB4000 portable spectrometer in absorbance mode. The SSC was measured using a digital refractometer.  The calibration and validation models were developed using the iPLS regression using original spectra. The calibration results showed that the root mean square of cross-validation (RMSECV) of first six subintervals from 582-831 nm was lower than that of the average of RMSECV and these subintervals were selected for developing final iPLS regression. Using the selected subintervals the calibration has high quality of prediction with RPD = 3,35. Keywords: NIR spectroscopy, soluble solids content, absorbance mode, nondestructive   method, snake fruit, iPLS regression

Abstract

Mushrooms are plants that have a nucleus, spores, no chlorophyll and are heterotrophic. Mushrooms can not produce their own food, they get nutrition by way of absorption. Nutrients are absorbed from the mushrooms existing in the organic material in which they live (Alexopoulos and Mims, 1996). Baglog is a media into the growth of mushrooms which comprises a mixture of basic materials such as wood sawdust, rice bran, limestone and so on. The mixture will be allowed to stand for 2-3 days so that all the materials decompose properly. All the material that has decomposed properly inserted into the plastic which will then be compacted. This media must be completely solid to support the growth of mushrooms. Compaction is done by using a press baglog mushrooms (Sunarmi and Saparinto, 2010). Keywords: mushroom baglog, two cylinder, electric motor

Abstract

Klasifikasi madu blossom dan madu honeydew menggunakan data spektra di panjang gelombang 190-400 nm belum dilakukan. Penelitian ini bertujuan untuk mengevaluasi penggunaan UV spektroskopi untuk klasifikasi madu flora yaitu madu Durian (Durio zibethinus) dan madu honeydew dari jenis ekstraflora yaitu madu Akasia (Acacia crassicarpa) dan madu Karet (Hevea brasiliensis) dari Indonesia. Sampel madu diencerkan dengan air distilasi dengan perbandingan 1:20 dan 1:30 (volume/volume) dan diteteskan sebanyak 3 mL ke dalam kuvet kuarsa. Spektra UV diukur menggunakan UV-visible spectrometer di rentang panjang gelombang 190-400 nm dengan interval 1 nm menghasilkan 211 variabel spektra. Model klasifikasi linear dibangun menggunakan metode linear discrimination analysis dan non-linear menggunakan metode support vector machine. Hasil penelitian menunjukkan kedua metode tersebut dapat digunakan untuk klasifikasi madu flora dan ekstraflora dengan nilai akurasi, sensitivitas, spesifisitas, presisi, dan koefisien korelasi Matthews sebesar 1 atau 100%. Hal ini menunjukkan aplikasi metode UV spektroskopi sebagai metode analisis yang cepat, ramah lingkungan dan harga relatif terjangkau untuk diskriminasi madu flora dan ekstraflora di Indonesia.
