Abstract

Briquettes represent environmentally sustainable solid fuels that utilize renewable resources. This study aimed to assess the quality of bagasse waste briquettes as an alternative in eco-friendly technology. The experimental method was conducted internally at the PT SUCOFINDO Bengkulu laboratory. Briquettes were produced using varying compositions of bagasse waste: A1 (80 grams charcoal flour and 12 grams tapioca flour), A2 (30 grams charcoal flour and 6 grams tapioca flour), and A3 (20 grams charcoal flour and 5 grams tapioca flour). The production process involved preparation, drying, monitoring, grinding, adhesive mixing, molding, and final drying. Quantitative data analysis focused on key parameters including water content, ash content, and calorific value. Results indicated that the briquettes with 80% charcoal flour and 20% tapioca flour exhibited the highest calorific value at 6155 kcal/kg. It was concluded that all types of bagasse waste briquettes met Indonesian National Standards, demonstrating their potential as an alternative energy source through environmentally friendly briquette technology.

Abstract

This research was conducted because of the difficulties experienced by students in learning, especially in the use of learning resources which still use printed books and worksheets in less interesting classroom learning. The gap that occurs between expectations and reality is that students expect learning to be more interactive, interesting and practical. This research aims to produce Android-based learning media products using integrated additives as smoked fish in the city of Bengkulu. The method applied is research and development (RND). This research uses a 4D development model (Define, Design, Development, and Disseminate). Development carried out is limited to the Development stage. The subjects of this research were 31 students in class VIII 2 of SMPN 3 Bengkulu City. Research instruments include observation, teacher interview sheets, student readability test sheets and expert validation sheets. The results of the research show that Android-based learning media on integrated smoked fish additive material is very suitable for use based on validation results from two validators, namely two material experts, two media experts, and practitioners. The learning media validation score by material experts was 88 in the "very feasible" category, the validation result by media experts was 87 in the "very feasible" category. And the practitioner validation results were 91 which were in the "very feasible" category. And the results of student responses to the media were 92 in the "very good" category. It can be concluded that Android-based learning media is very feasible and very good for use in junior high school science learning on additive material. For further training, it is possible to carry out secondary school education learning activities aimed at by the next training.

Abstract

Makroinvertebrata merupakan organisme tidak bertulang belakang yang memiliki ukuran kasat mata, memiliki habitat di darat, dalam  tanah, perairan meliputi air laut dan tawar. Kelompok makroinvertebrata di perairan bisa dijadikan bioindikator suatu perairan. Makroinvertebrata di perairan air tawar contohnya kelompok keong air tawar, serangga air, udang dan Clitellata seperti lintah. Penelitian dilakukan pada bulan Oktober 2023 sampai Januari 2024 menggunakan teknik purposive sampling. Pengambilan sampel menggunakan leaf litter bags, jaring seser, dan mengambil sedimen dasar perairan menggunakan ember. Pengukuran parameter lingkungan dilakukan meliputi pengukuran intensitas cahaya, suhu air, tingkat keasaman (pH), oksigen terlarut (DO), kedalaman lumpur, dan kedalaman air. Analisis data menggunakan indeks Shannon-Wiener, indeks Eveness dan indeks Simpson. Hasil identifikasi makroinvertebrata menunjukkan terdapat 16 spesies terdiri atas 13 famili dan 4 kelas. Indeks keanekaragaman makroinvertebrata di area kolam konservasi ex-situ kura-kura Siebenrockiella crassicollis Universitas Bengkulu secara umum tekanan ekologis berada pada kondisi tekanan rendah hingga sedang, dapat dilihat pada nilai H’ berkisar antara 0,981 sampai 1,577, indeks keseragaman berkisar antara 0,354 sampai 0,569 dan indeks dominansi berkisar antara 0,342 sampai 0,506. Kelimpahan, keanekaragaman, keseragaman dan dominansi makroinvertebrata dipengaruhi oleh parameter fisika kimia dan kondisi lingkungan.
