Abstract

Cookies are dry cakes made with flour as the primary baking ingredient. Spirulina platensis was rich in protein, amino acids, glycoproteins, essential fatty acids, polysaccharides, and beta-carotene. Therefore, using sago flour combined with spirulina and seaweed in cookies can increase the nutritional value and produce gluten-free cakes. This training aims to increase knowledge about spirulina, packaging, and product marketing strategies and the skills of Babakan village residents by providing training on making spirulina cookies. This community service activity was conducted by counseling and training on making spirulina cookies in Babakan Village, Dramaga. Counseling activities were carried out to increase knowledge about the potential of spirulina, good packaging, and product marketing strategies, as well as training on making spirulina cookies to improve the skills of Babakan village residents. There were 18 training participants: Family Welfare Empowerment administrators and members. Pre-tests and post-tests were carried out before and after the training activities regarding the topic provided by the speakers. The achievements of the training activities were seen from an increase in post-test results, which was 60% answered correctly compared to only 40% for the pre-test. The evaluation results of the participant's acceptance of training topics and training speakers had an average of 58 to 69%, respectively, perfect. While the participants's assessment of the training facilities and consumption had an average of 50%, they were good.

Abstract

The crab canning industry in Pemalang Regency has been built for over three decades and has become the largest in Indonesia, with 13 mini-plant units. Boiling and stripping are the main activities that produce a large amount of waste, causing pollution. The crab waste currently utilized by the local community as animal feed. Therefore, disseminating knowledge and skills regarding diversification and product development is necessary. The training aimed to deliver knowledge and skills concerning diversification and development of products for the mini-plant in Pemalang. Training consists of pre-activities, delivery of innovative content, development of various by-products, and evaluation. The innovative topic includes handling and potential use as instant food, snacks, seasoning, nova ingredients, and other non-food products. Diversification includes the innovation of traditional community-based products (tempe rajungan (teraja) and abon vegetable rajungan anaraja), innovation of regionally processed products ("cactus crab" similar to the typical snack of Pemalang "ogel ogel"), instant and seasoning as well (soup cream, petis, and souce). The response rate/change in knowledge and skill attitudes is classified as very high, ranging from 70% to 100%. The post-activity evaluation after three months, a processors and marketers group (Poklasar) of various processed products named "Gira Sari," with the primary production of snacks for souvenirs. Local extension workers accompany the Gira Sari Group in the activity. Challenges such as non-standard utensils, raw materials, packaging, lack of business strategy knowledge, and financial analysis require immediate solutions.

Abstract

AbstrakKemajuan teknologi di era digitalisasi telah mendorong kebutuhan baterai sebagai perangkat penyimpan energi. Baterai memiliki peran dalam menyediakan sumber daya untuk berbagai aplikasi pada perangkat elektronik yang semakin kompleks. Baterai konvensional cenderung memiliki dampak negatif bagi lingkungan karena menggunakan polimer sintesis yang tidak ramah lingkungan, seperti polietilen dan poliopropilen, serta menghasilkan limbah bahan, beracun, dan berbahaya (B3). Selain itu, baterai umumnya mengandung bahan kimia berbahaya seperti merkuri, mangan, timbel, nikel, litium, dan kadmium. Inovasi akan energi terbarukan dan teknologi terbarukan diperlukan untuk mengurangi kerusakan lingkungan. Penelitian ini bertujuan untuk menganalisis pengaruh penambahan silikon dioksida dengan menentukan rasio yang terbaik terhadap peningkatan elektrisitas serta kinerja baterai fleksibel berbasis karaginan-PVA. Metode yang digunakan meliputi persiapan membran dengan rasio yang bervariasi, karakteristik membran, analisis elektrisitas, analisis gugus fungsi FTIR, water uptake, konduktivitas proton, dan kuat tarik baterai fleksibel. Hasil analisis FTIR menunjukkan bahwa interaksi antar komponen bersifat fisik tanpa pembentukan gugus fungsi baru. Penambahan silikon dioksida tidak memberikan pengaruh signifikan pada seluruh parameter, akan tetapi dapat berperan dalam menjaga stabilitas mekanik dan konduktivitas ionik. Performa elektrik terbaik menghasilkan tegangan 0,25 V, arus 0,025 A, dan daya 5,7 mW. Karakteristik membran menunjukkan nilai water uptake tertinggi 56,8%, konduktivitas proton 8,81 x 10⁻⁶ S/cm, serta kuat tarik 5,39 MPa. Kombinasi rasio material yang seimbang menghasilkan membran baterai fleksibel dengan stabilitas struktural yang baik.AbstractTechnological progress in the digital era has increased the demand for batteries as energy-storage devices. Batteries play a key role in supplying power for increasingly complex electronic applications. Conventional batteries tend to have adverse environmental impacts because they rely on non-biodegradable synthetic polymers such as polyethylene and polypropylene and generate toxic and hazardous waste. They also commonly contain hazardous chemicals including mercury, manganese, lead, nickel, lithium, and cadmium. Innovation in renewable energy and sustainable technology is therefore needed to reduce environmental damage. This study analyses the effect of adding silicon dioxide and determines the optimum ratio for improving the electrical performance of carrageenan–PVA-based flexible batteries. The methods comprised membrane preparation at varying ratios, membrane characterisation, electrical analysis, FTIR functional-group analysis, water uptake, proton conductivity, and tensile strength testing. FTIR analysis showed that the interaction between components was physical, with no new functional groups formed. The addition of silicon dioxide did not significantly affect any parameter, but it contributed to maintaining mechanical stability and ionic conductivity. The best electrical performance produced a voltage of 0.25 V, a current of 0.025 A, and a power output of 5.7 mW. Membrane characterisation showed a maximum water uptake of 56.8%, a proton conductivity of 8.81 × 10⁻⁶ S/cm, and a tensile strength of 5.39 MPa. A balanced combination of material ratios produced a flexible battery membrane with good structural stability.
