Abstract

Pagaruyung Village is the largest pineapple producer in Kampar Regency with sales of 10.330 tons per year. The main problem faced by Pagaruyung Village as a pineapple producing center is that most of the pineapples produced are sold fresh at low prices, around Rp. 3,000-5,000 per fruit, so that there are often several obstacles in the distribution of fresh pineapples related to quality, storage, and transportation. Pineapples can be processed into other processed products such as syrup. Syrup is a processed food product that has a long shelf life and a simple production stage. Pineapple syrup can be an effective solution as well as a characteristic of the village to attract local and international tourists, as well as support independent food security efforts.The aim of the community service program through mentoring activities is that Pagaruyung Village, Tapung District, can become an entrepreneurial village in order to create an independent village and improve the economy of village communities through synergy between Riau University as a university and assisted villages within the scope of Riau Province. In this activity, an approach was taken through socialization regarding various processed products made from pineapple, direct practice in making pineapple syrup using simple technology, as well as evaluating activities using a questionnaire. The results of this training reveal the community's innovation and enthusiasm in processing pineapple into pineapple syrup. To achieve the main goal, namely improving the local economy and making Pagaruyung Village a tourist destination, ongoing coaching and training efforts are needed.

Abstract

One efficient method to prevent infections spread by mosquitoes is to use repellent. However, when used regularly over an extended period, insect repellents containing DEET commonly available on the market may induce adverse effects such as hypersensitivity, irritation, and hives. Pineapple and sweet orange peels can be utilized as natural ingredients in mosquito-repelling lotions because they contain various secondary metabolites, including tannins, saponins, flavonoids, alkaloids, steroids, and essential oils. This study aimed to find the optimal concentration of pineapple peel extract based on the characteristics of the produced mosquito repellent lotion. The experiment used a completely randomized design (CRD), producing 15 experimental units with five treatments—pineapple peel extract concentrations—each with three replications: 2%, 3%, 4%, 5%, and 6%. The lotion with a 6% concentration of pineapple peel extract (LNJ5) was selected due to its homogenous physical characteristics, pH of 7.89, spreadability of 6.98 cm, viscosity of 2131.02 cP, and mosquito protection rate of 88.64%. The lotion had a yellowish-brown color, a faint pineapple and orange scent, and a descriptive organoleptic evaluation that panelists found pleasing

Abstract

Populasi dunia yang terus bertambah pesat, ketersediaan bahan bakar fosil semakin menurun, sehingga diperlukan alternatif energi lainnya yang berasal dari energi terbarukan yang ramah lingkungan seperti pemanfaatan bioetanol. Bioetanol dapat berasal dari tumbuhan, yang mengandung gula seperti pati atau selulosa. Pati yang terkandung pada bahan akan dikonversi menjadi gula dan selanjutnya diubah menjadi bioetanol. Buah mangrove api-api berpotensi sebagai bahan baku dalam pembuatan bioetanol. Kandungan karbohidrat yang terdapat di buah mangrove api-api ini bisa dimanfaatkan menjadi bahan baku pembuatan bioetanol. Penelitian bertujuan untuk mendapatkan lama fermentasi terbaik terhadap kualitas bioetanol buah mangrove api-api. Penelitian menggunakan metode Rancangan Acak Lengkap (RAL) yang terdiri dari lima perlakuan lama fermentasi (4, 5, 6, 7, dan 8 hari) dan tiga kali pengulangan. Parameter yang diuji meliputi kadar bioetanol, rendemen bioetanol, derajat keasaman bioetanol, dan uji warna bioetanol. Data dianalisis secara statistik menggunakan analysis of variance (ANOVA) dilanjutkan dengan Duncan’s  Multiple Range Test (DMRT) pada taraf 5%. Hasil analisis menunjukkan bahwa lama fermentasi pada pembuatan bioetanol berpengaruh signifikan terhadap kadar bioetanol, rendemen bioetanol dan derajat keasaman bioetanol, namun tidak berpengaruh secara signifikan terhadap uji warna bioetanol. Perlakuan P4 (7 hari lama fermentasi) dipilih sebagai perlakuan terbaik, dengan kadar bioetanol 12,24%, rendemen bioetanol 28,89%, tingkat keasaman 5,46, dan indeks warna L* 32,32%, a* 3,17, b* 2,10.

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.
