Abstract

This study aims to develop sago starch-based bioplastics with the addition of modifying agents such as acetic acid, chitosan, and glycerin to improve mechanical properties, elongation, and biodegradability. The results showed that the optimal combination was reached at 4% acetic acid and 2% chitosan concentration, resulting in the highest tensile strength of 8 MPa, elongation at break of 26%, and degradation rate of 70%. At this condition, the bioplastic matrix has an optimal balance between strength, flexibility, and degradability. Increasing the acetic acid concentration to 6% caused a decrease in tensile strength to 4.2 MPa and elongation at break to 14%, indicating degradation of the matrix structure due to excess acid. Chitosan also affected the mechanical properties, where increasing its concentration from 2% to 4% tended to decrease the elongation at break. The degradation rate tended to increase with higher concentrations of acetic acid, reaching 82% at 6% acetic acid concentration with 2% chitosan, while higher concentrations of chitosan (4%) slowed down the degradation due to a denser and stronger matrix structure. Overall, the combination of sago starch, acetic acid, chitosan, and glycerin produced bioplastics that have improved mechanical properties, water resistance, and environmental friendliness, making them a potential alternative to replace conventional plastics in various industrial applications. These findings support the development of environmentally friendly materials that can reduce the negative impacts to the environment in general and in Papua as the local producer of Sago.

Abstract

Difficulties with foundational arithmetic operations remain a persistent impediment to mathematical progression among primary and lower secondary school students in Indonesia, and are frequently compounded by pedagogical approaches that prioritise rote memorisation over conceptual understanding. This paper presents findings from two successive structured intervention studies examining the short-term efficacy of the Matematika GASING (Gampang, Asyik, Menyenangkan—Easy, Fun, Enjoyable) method across all four basic arithmetic operations: addition, multiplication, subtraction, and division. Study 1 (n = 24) was conducted at GGP Jemaat Ayalon Church, Argapura Resimen, Jayapura, and focused on addition and multiplication. Study 2 (n = 30) was conducted at GKPMI Jemaat Ekklesia Church, Ardipura II, Jayapura, and focused on subtraction and division. Both studies employed a one-group pre-test/post-test design. In Study 1, all five arithmetic sub-items showed positive gains, with multi-digit addition recording the highest absolute gain (+37 percentage points (pp)) and multiplication sub-items yielding a consistent +20 pp gain each. In Study 2, all seven sub-items improved, with two-digit division recording the largest relative gain (+38 pp). Across both studies and all twelve assessed sub-items, the Matematika GASING method produced consistent and educationally meaningful short-term arithmetic gains. The intervention incorporated concrete–pictorial–abstract (CPA) sequencing, mnemonic songs with movement, manipulative place-value cards, and prize-incentivised oral drills. The findings extend the GASING evidence base to non-formal community settings in Papua, and to all four basic operations within a unified research programme.

Abstract

Penelitian ini bertujuan untuk mengeksplorasi secara mendalam integrasi etnosains Papua dalam pembelajaran IPA di sekolah dasar, khususnya memetakan hambatan praktis yang dihadapi guru, kebingungan konseptual peserta didik, dan potensi budaya di sekitar lingkungan sekolah. Menggunakan desain studi kasus kualitatif, data dikumpulkan melalui observasi awal, dokumentasi, dan wawancara mendalam dengan dua guru kelas V, tiga peserta didik kelas V, dan dua tokoh masyarakat sebagai informan kunci di SD Negeri Inpres 1 Koya Timur, Kota Jayapura, Papua. Hasil penelitian menunjukkan adanya kesenjangan (missing link) yang signifikan antara kesadaran konseptual dan eksekusi praktis di kelas. Meskipun guru memiliki persepsi yang sangat positif terhadap etnosains, implementasi nyata sangat terhambat oleh keterbatasan alokasi waktu kurikulum dan kurangnya fasilitas pendukung sehingga guru menyederhanakan integrasi sebatas pada praktik tarian adat. Dampaknya, peserta didik kelas V mengalami disorientasi konseptual dan merasa bingung ketika mencoba mengorelasikan istilah ilmiah abstrak dalam buku teks seperti komponen biotik, keanekaragaman hayati, dan teknologi kuliner dengan budaya asli mereka. Sebaliknya, wawancara dengan tokoh masyarakat mengungkap melimpahnya materi budaya dan alam yang belum dimanfaatkan di sekitar sekolah seperti pohon sagu, pohon pinang, papeda, serta alat musik tradisional tifa. Objek-objek tersebut memiliki potensi besar untuk bertindak sebagai alat peraga alternatif dan laboratorium alam yang efisien guna mengatasi keterbatasan fasilitas sekolah. Penelitian ini merekomendasikan perlunya pengembangan modul dan lembar kerja peserta didik (LKPD) berbasis etnosains Papua yang terstruktur untuk menjembatani sains formal dengan budaya sehari-hari peserta didik.

Abstract

Coconut shell waste has become an environmental challenge in rural areas of Indonesia due to limited waste management practices. However, this waste has the potential to be utilized as a renewable energy source, prompting the community service program to increase community awareness and skills in Skouw Mabo Village through the revitalization of coconut shell waste into charcoal as a value-added product. The activities included coordination with village stakeholders, field surveys, educational sessions, and Focus Group Discussions (FGDs) to explore community perceptions and identify opportunities for sustainable waste management. The results demonstrated that the community welcomed the program and implied the importance of strengthening waste management infrastructure and environmental education. Participants recognized the potential of composting and anaerobic digesters for organic waste management and identified coconut shell waste as a promising resource for charcoal and briquette production to support the transition from preexisting liquefied petroleum gas (LPG) to renewable energy. The practical demonstration encouraged active community participation in converting coconut shell waste into charcoal, reducing unmanaged waste while creating opportunities for local renewable energy utilization. Overall, the program strengthened community awareness, promoted sustainable solid waste management, and supported renewable energy development in Skouw Mabo Village.
