Abstract

Kulit buah salak dapat menjadi bahan dasar pembuatan arang aktif karena mengandung senyawa selulosa, hemiselulosa, dan lignin yang berpotensi tinggi sebagai sumber karbon. Pemanfaatan limbah kulit buah salak sebagai bahan baku arang aktif juga merupakan upaya dalam mengurangi limbah agroindustri sekaligus meningkatkan nilai tambahnya. Pembuatan arang aktif dari kulit buah salak dilakukan melalui dua tahap utama, yaitu proses karbonisasi dan aktivasi. Aktivasi kimia menggunakan bahan kimia ZnCl2 sebagai aktivator diketahui dapat menghasilkan mutu arang aktif yang lebih baik dibandingkan aktivasi fisika. Penelitian ini bertujuan untuk menentukan konsentrasi aktivator seng klorida (ZnCl2) terbaik dalam pembuatan arang aktif kulit buah salak asal Padangsidimpuan. Penelitian dilaksanakan secara eksperimental menggunakan rancangan acak lengkap (RAL) dengan enam perlakuan konsentrasi ZnCl2 (5%, 10%, 15%, 20%, 25%, dan 30%) dan tiga ulangan. Data hasil penelitian dianalisis menggunakan Analysis of Variance (ANOVA) dan dilanjutkan dengan uji Duncan’s Multiple Range Test (DMRT) pada taraf signifikansi 5%. Hasil menunjukkan bahwa variasi konsentrasi aktivator berpengaruh nyata terhadap rendemen, kadar air, kadar abu, kadar zat volatil, kadar karbon terikat, dan daya serap iodium. Aktivasi dengan ZnCl2 30% memberikan hasil terbaik dengan rendemen 62,29% dan serapan iodium 960,25 mg/g, serta kadar air, abu, zat volatil, dan karbon terikat masing-masing 7,15%, 8,32%, 3,96%, dan 80,56%.

Abstract

Pagaruyung Village in Kampar Regency is one of the largest pineapple-producing centers in Riau Province and is being developed as a pineapple-based food processing center. However, the increase in the number of foodMSMEs in this village has not been accompanied by adequate understanding regarding the application of food labels according to BPOM regulations and the fulfillment of halal business legality required by BPJPH. This community service activity aimed to increase the knowledge of MSME actors regarding proper and correct food labeling, as well as the application of MSME halal business legality. This training was held on October 11, 2025, and was attended by 17 participants. The implementation methods used for this service activity include a pretest, material presentation, mentoring, discussion, and a final evaluation in the form of a posttest. The evaluation results showed a significant improvement in participants' understanding, with a 98% presentation rate regarding the proper and correct application of food labels and halal certification for MSMEs. This activity makes an important contribution to increasing the readiness of Pagaruyung Village MSMEs to produce pineapple products that are safe, of high quality, and meet food legality standards.

Abstract

Herbal tea is a beverage prepared from plant materials other than Camellia sinensis and has gained attention due to its functional properties. Avocado (Persea americana) leaves are a potential raw material for herbal tea because they contain bioactive compounds with antioxidant activity. This study evaluated the effect of blanching time on the quality of avocado (Persea americana) leaf herbal tea and determined the optimal treatment. A randomized controlled experiment was conducted using four blanching durations (0, 5, 10, and 15 min) with 16 experimental units. Moisture content, ash content, antioxidant activity, tannin content, and sensory acceptance were analyzed. Statistical analysis was performed using ANOVA followed by Duncan’s Multiple Range Test at a 5% significance level. Blanching time significantly affected the physicochemical and sensory properties of the herbal tea. The 15-minute blanching treatment produced the best quality, with moisture content of 4.11%, ash content of 6.46%, antioxidant activity of 41.66 ppm (very strong), and tannin content of 0.0121%. Sensory evaluation showed a yellow color, a slightly stale aroma, a non-bitter taste, and moderate overall acceptance. These results indicate that 15-minute blanching is optimal for producing high-quality avocado leaf herbal tea.

Abstract

Sago tempe chips are snacks made from soybeans and sago flour. The packaging of sago tempe chips uses transparent plastic with label stickers, making it appear simple and less attractive to consumers. One strategy to attract consumers is redesigning the packaging using the kansei engineering approach. This study aims to produce a packaging design for sago tempe chips that suits consumer preferences using a kansei engineering approach. This study helps produce packaging designs that suit consumer desires and needs so that they can attract consumers. The method used is a survey with a kansei engineering approach. Based on this study, eight kansei words were identified, namely informative, unique, artistic, attractive, quality, easy to use, innovative, and colorful. The packaging design concepts extracted from the kansei words using principal component analysis (PCA) were identified as “informative,” “colorful,” and “quality.” The design elements identified from the 10 packaging samples included shape, supporting images, materials, color, and size. Based on the R-squared value of quantification theory type 1 (QTT1), the concept of “quality” was selected because it had a higher value. Tempe sagu chip packaging is considered quality if it has a pillow-shaped bag design, features product images, uses aluminum foil material, employs multiple colors (>3 colors), and has a medium-sized package.

Abstract

Sago starch and sweet potato starch are promising alternatives for wet noodle production due to their high amylose and amylopectin content, which contribute to desirable quality characteristics. This study was conducted to determine the effect of the ratio of starch (sago and sweet potato respectively) to mung bean flour on the physicochemical properties of wet noodles, as well as to obtain the best wet noodle formulation. The research was conducted experimentally using a completely randomized design with ten treatments and four replicates. The treatments involved varying ratios of starch to mung bean flour for sago starch-based noodles (SP1: 100:0, SP2: 80:20, SP3: 70:30, SP4: 60:40, SP5: 50:50) and sweet potato starch-based noodles (JP1: 100:0, JP2: 80:20, JP3: 70:30, JP4: 60:40, JP5: 50:50). Parameters measured for the starches included water holding capacity (WHC), swelling power, and solubility. Wet noodle parameters included moisture, ash, and protein content, elongation, water absorption, and sensory characteristics (color, aroma, taste, chewiness, and overall preference). Data were analyzed statistically using ANOVA and further evaluated with DMRT at a 5% significance level. Results showed that different ratios of sago or sweet potato starch and mung bean flour significantly affected all observed parameters. Among the treatments, JP4 (60:40) received the highest hedonic scores, indicating panelists’ preference for all sensory attributes, including color, aroma, taste, chewiness, and overall acceptability. This study demonstrates the potential of using sago starch and sweet potato starch with mung bean flour substitution to develop wet noodles that meet both sensory and nutritional quality standards.

Abstract

Pirolisis tempurung kelapa menggunakan tungku terbuka atau kiln sederhana masih menghadapi kendala berupa suplai oksigen yang tidak terkendali, suhu karbonisasi yang kurang stabil, rendemen arang yang rendah, serta proses pembongkaran produk yang kurang ergonomis. Penelitian ini bertujuan merancang dan memfabrikasi kiln pirolisis tempurung kelapa tipe batch dengan mekanisme poros pemutar dan ventilasi udara terbatas untuk mendukung proses karbonisasi yang lebih terkendali dan mudah dioperasikan. Perancangan dilakukan melalui pendekatan rekayasa yang mencakup penentuan kapasitas bahan 20 kg, volume ruang pengarangan, kebutuhan energi pemanasan awal, debit udara pembakaran parsial sebesar 0,00456 m³/s, konfigurasi lubang udara, serta sistem cerobong natural draft berdiameter 3 inci yang direduksi menjadi 1 inci. Hasil fabrikasi menghasilkan prototipe kiln berbentuk silinder vertikal berdiameter 37 cm yang dipasang pada rangka penyangga berbentuk A dengan poros horizontal, sehingga badan kiln dapat dimiringkan secara manual untuk memudahkan pengeluaran arang tanpa pintu samping. Inspeksi dimensional dan fungsional menunjukkan bahwa ruang pengarangan, ventilasi, cerobong, rangka penyangga, dan mekanisme pemutar telah terpasang sesuai rancangan. Prototipe ini menjadi dasar untuk pengujian kinerja termal, distribusi suhu, rendemen arang, dan kualitas produk pada tahap berikutnya. Rancangan ini berpotensi diterapkan pada skala UMKM sebagai kiln pirolisis yang lebih operasional, terkendali, dan mudah direplikasi.
