Abstract

This study aims to analyze water quality and heavy metal lead (Pb) content in the waters of Class II Port of Jayapura, Papua. Increased port and industrial activities in coastal areas can contribute to environmental pollution, including heavy metal contamination that impacts marine ecosystems and the health of coastal communities. This research employed a descriptive method with water sampling at 2 stations, each consisting of 3 sub-stations using purposive sampling technique. Seawater samples were analyzed at the Chemistry Education Laboratory of Cenderawasih University using Atomic Absorption Spectrophotometry (AAS). Water quality parameters measured included temperature, pH, Dissolved Oxygen (DO), transparency, and salinity. The results showed that water quality parameters were within safe ranges according to quality standards, with temperature ranging from 30.2-32.5°C, pH 6.54-7.60, DO 5.45-8.55 mg/l, transparency 3.20-3.57 meters, and salinity 30-34. However, the heavy metal lead (Pb) content in seawater ranged from 0.115-0.141 mg/l, which exceeded the established quality standard limit of 0.05 mg/l based on Government Regulation Number 22 of 2021 and Minister of Environment Decree Number 51 of 2004. This research indicates that port activities such as loading and unloading of goods, ship washing, fuel usage, fuel spillage, and use of ship coating paint can affect the level of lead in the waters. Special attention and strict supervision of port activities are required to minimize heavy metal pollution in the waters of Jayapura Port.

Abstract

Louhan fish are predatory fish from Lake Sentani that can be processed into fishery products such as nuggets. Nuggets are created from a mixture of crushed fish meat, flour, and other ingredients, then coated with flour. This initiative aims to enhance the skills of partners in processing louhan fish into nugget products. The partners in this community service activity are mothers at the Al-Manshurin Islamic Boarding School in Waena, who lack creativity in processing louhan fish into various products. The challenge faced by the partners is a lack of knowledge regarding the louhan fish processing. Therefore, the solution provided is training in making louhan fish nuggets. The community service activity was conducted at the Al-Manshurin Islamic Boarding School, located in Waena, Jayapura City. The methods employed were socialization, practice, and evaluation. Twenty participants attended this community service activity. The participatory role of partners in this activity is to be actively involved in all stages, from socialization and practice to evaluation. The community service activities conducted by the team demonstrated a 100% increase in the skills of all mothers at the Al-Manshurin Waena Islamic Boarding School in making louhan fish nuggets after the processing practice.

Abstract

Penelitian ini bertujuan untuk menganalisis hubungan dan pengaruh keterlibatan siswa melalui penerapan model Guided Discovery Learning terhadap hasil belajar materi fenomena pemanasan global di kelas X-B SMA Negeri 7 Jayapura tahun ajaran 2025/2026. Penelitian menggunakan pendekatan kuantitatif dengan desain deskriptif korelasional. Populasi sekaligus sampel penelitian berjumlah 33 siswa kelas X-B IPA yang dipilih menggunakan teknik sampling jenuh. Data keterlibatan siswa dikumpulkan melalui angket skala Likert, sedangkan hasil belajar diukur menggunakan tes pilihan ganda. Analisis data dilakukan melalui uji normalitas, uji korelasi, dan uji pengaruh. Hasil penelitian menunjukkan adanya hubungan positif dan signifikan antara keterlibatan siswa dalam pembelajaran Guided Discovery Learning dengan hasil belajar siswa. Keterlibatan siswa memberikan pengaruh sebesar 15,29% terhadap hasil belajar, sementara sisanya dipengaruhi oleh faktor lain seperti kemampuan awal siswa, motivasi belajar, dan lingkungan belajar. Temuan ini menunjukkan bahwa semakin tinggi keterlibatan siswa, maka semakin baik hasil belajar yang dicapai. Oleh karena itu, model Guided Discovery Learning direkomendasikan sebagai alternatif pembelajaran untuk meningkatkan keterlibatan siswa dan hasil belajar kimia pada materi berbasis isu lingkungan

Abstract

Keterlibatan siswa merupakan faktor penting dalam pembelajaran kimia karena berperan dalam meningkatkan aktivitas belajar, motivasi, dan pemahaman konsep. Namun, pembelajaran kimia pada materi reaksi kimia dan penyetaraan reaksi masih menunjukkan tingkat keterlibatan siswa yang belum optimal akibat pendekatan pembelajaran yang berpusat pada guru. Penelitian ini bertujuan untuk menganalisis tingkat keterlibatan siswa serta hubungan dan pengaruh keterlibatan siswa terhadap hasil belajar setelah diterapkannya model Cooperative Learning Together. Penelitian ini menggunakan pendekatan kuantitatif dengan desain korelasional. Subjek penelitian terdiri atas 32 siswa kelas X-B SMA Negeri 7 Jayapura Tahun Ajaran 2025/2026. Data keterlibatan siswa dikumpulkan melalui angket yang mencakup aspek perilaku, emosional, dan kognitif, sedangkan data hasil belajar diperoleh melalui tes akhir (posttest). Analisis data dilakukan menggunakan statistik deskriptif, uji korelasi Pearson, dan regresi linear sederhana. Hasil penelitian menunjukkan bahwa keterlibatan siswa berada pada kategori tinggi dengan persentase keterlibatan perilaku sebesar 76,51%, emosional sebesar 67,37%, dan kognitif sebesar 64,31%. Hasil belajar siswa juga berada pada kategori tinggi dengan nilai rata-rata sebesar 65,91%. Uji korelasi menunjukkan adanya hubungan positif dan signifikan antara keterlibatan siswa dan hasil belajar (r = 0,511; p < 0,05), sedangkan analisis regresi menunjukkan bahwa keterlibatan siswa memberikan kontribusi sebesar 26,12% terhadap variasi hasil belajar. Dengan demikian, penerapan model Cooperative Learning Together berpengaruh positif terhadap keterlibatan siswa dan hasil belajar kimia.

Abstract

Penelitian ini bertujuan untuk menganalisis peran bakat sebagai faktor pendukung dan penghambat dalam pembelajaran kimia pada materi sistem periodik unsur. Penelitian menggunakan pendekatan kuantitatif deskriptif dengan melibatkan 32 siswa kelas X salah satu SMA Negeri di Jayapura. Data dikumpulkan melalui tes hasil belajar dan tes bakat yang meliputi bakat verbal, numerikal, skolastik, mekanik, abstrak, serta kecepatan dan ketelitian klerikal. Hasil penelitian menunjukkan bahwa seluruh siswa mencapai nilai di atas KKM (70), namun variasi hasil belajar tidak selalu sejalan dengan profil bakat. Bakat abstrak, skolastik, dan ketelitian klerikal menunjukkan kontribusi lebih signifikan terhadap hasil belajar dibandingkan bakat verbal, numerikal, dan mekanik. Penelitian ini menegaskan bahwa keberhasilan belajar kimia ditentukan oleh kesesuaian antara jenis bakat dan karakteristik materi pembelajaran.
