Abstract

Problem-solving ability and entrepreneurial interest are the kinds of skills that must be owned by the students to face the world of work and citizenship in the 21st century. The PjBL model through waste product development projects as a solution to solving environmental problems is considered a potential learning strategy for developing problem-solving ability and entrepreneurial interest student. The background of SMA Negeri 1 Kersana as an adiwiyata school which has various waste management and processing activities has the potential to implement projects to manage old leaf waste into leaf skeleton craft products. This research aims to analyze the effectiveness of the PjBL model on students' problem-solving ability and entrepreneurial interest in environmental change material, and analyze the relationship between problem-solving ability and entrepreneurial interest in learning the PjBL model. This research used pre experimental design with the one shot case study. The population in this study were class X students of SMA Negeri 1 Kersana who received biology subjects for the 2023/2024 school year. Sampling was carried out using cluster random sampling technique, the sample in this study was class X-2 with 36 students. The test instruments was used to measure students' problem solving ability while questionnaire instruments was used to measure entrepreneurial interest. The average score of problem solving ability was 77.05 and the posttest classical completeness of problem solving ability was 91.67%. The average score ofentrepreneurial interest was 83.9 and the criteria level for entrepreneurial interest is good at 27.78%, very good at 72.22%. Based on these results, it can be  concluded that PjBL is effective on students' problem-solving ability and entrepreneurial interest in environmental change material. The results of a simple linear regression test between problem solving ability and students' entrepreneurial interest show tcount > ttable, namely 2.466 > 2.032 and a significance level of 0.019 < 0.05, so there is a significant positive relationship between problem solving ability and students' entrepreneurial interest in the PjBL learning model.

Abstract

The increase in GHGs in Semarang City, caused by the increase in motorized vehicles and industrial activity, has resulted in a decrease in environmental quality in urban areas and air pollution. Data from the Semarang City Environmental Service (2019), shows that total CO2e emissions in 2018 were dominated by CO2, namely 33,505,357.22 tons of CO2 (85.24%) of the total CO2e tons of GHG emissions. To reduce CO2 emissions in Semarang City, one way that can be done is by utilizing urban forests which can absorb carbon dioxide. Based on these conditions, estimates of stored carbon reserves and carbon uptake in urban forests need to be calculated to determine the CO2 that plants in urban forests can absorb. This research aims to analyze the amount of stored carbon reserves and carbon uptake in the Tinjomoyo Semarang City Forest ecosystem. This research uses an exploratory method carried out through direct observation and measurement in the field. The sampling technique used is the belt transect method. The stand measurement method is carried out using the Non-Destructive Test (NDT) method or by not damaging the research samples. Stand data analysis was carried out using the allometric equation method. Based on calculation results, the number of individual stands in the Tinjomoyo Semarang City Forest area is 367 individual stands. The total amount of biomass is 125.5 tonnes/ha, the total carbon stock is 57.72 tonnes/ha and the total amount of carbon uptake is 211.8 tonnes/ha. This research shows that the estimated carbon reserves stored in the Tinjomoyo City Forest ecosystem, Semarang are 57.72 tonnes/ha with a carbon uptake value of 211.8 tonnes/ha.

Abstract

Arthropods are the largest phylum in the Animalia kingdom that can live on land, in freshwater, in the sea, or in the air. Springs are bodies of water that seep out through cracks in rocks to the surface of the ground, serving as a habitat for various Arthropods and the Gunungpati district has several springs in its area. This study aims to analyze the diversity of arthropod species and to describe the abiotic and biotic factors that influence the diversity of arthropod species in the water bodies and around the springs in the Gunungpati district, Semarang City. The research was carried out from October to December 2022, located at five springs, among others. The research was conducted from October to December 2022 at five springs, namely Sendang Jedung, Sendang Lanang Trangkil, Sendang Ndelik, Sendang Mbiru, and Sendang Gede. The data collection method was purposive sampling. The approach used in this research is a quantitative approach with a descriptive research type. The research results showed a total of 1537 individuals and 112 species of arthropods, which included 146 individuals in water bodies and 1391 individuals around springs. The diversity index ranged from moderate to high, between 1.82-3.30. The dominance index values were low, ranging from 0.05-0.29, and the evenness index values fall within moderate to high criteria, ranging from 0.52-0.86. The Sorenson similarity index on the five ponds is considered low. Abiotic factors do not affect diversity too much because it has similar values in the five springs. Therefore, biotic factors (organic matter, litter, and surrounding vegetation) greatly influenced the diversity of arthropod species in water bodies and around the spring in Gunungpati District, Semarang City.

Abstract

Ketahanan pangan masyarakat menjadi salah satu tantangan pembangunan berkelanjutan yang memerlukan pemanfaatan sumber daya lokal secara optimal melalui pendekatan urban farming dan ekonomi sirkular. Diversifikasi produk olahan berbasis ikan lele sebagai salah satu komoditas budidaya perkotaan berpotensi meningkatkan nilai tambah hasil produksi sekaligus memperluas alternatif pangan bergizi bagi masyarakat. Kegiatan pengabdian kepada masyarakat ini dilaksanakan di Kelurahan Tambakrejo, Kecamatan Gayamsari, Kota Semarang, sebagai bagian dari Program Gerakan Masyarakat Hidup Sehat (Germas) Lawang Sewu. Kegiatan difokuskan pada penguatan urban farming melalui diversifikasi produk olahan lele berupa cookies yang dipadukan dengan edukasi ekonomi sirkular kepada kader posyandu, kader PKK, Forum Kesehatan Kelurahan (FKK), kelompok tani, pelaku UMKM, serta perangkat kelurahan. Evaluasi kegiatan menggunakan desain one-group pretest-posttest terhadap 12 peserta dengan instrumen sebanyak 10 butir pertanyaan. Hasil menunjukkan skor rata-rata pretest sebesar 9,50 (SD=1,17) dan posttest sebesar 9,83 (SD=0,39), dengan korelasi yang kuat dan signifikan antara kedua pengukuran (r=0,800; p=0,002). Meskipun demikian, hasil paired t-testmenunjukkan peningkatan skor belum signifikan secara statistik (t=1,301; df=11; p=0,220), yang diduga dipengaruhi oleh ceiling effect karena tingkat pengetahuan awal peserta telah relatif tinggi sebelum kegiatan dilaksanakan. Secara keseluruhan, kegiatan ini menunjukkan bahwa diversifikasi produk olahan lele berbasis ekonomi sirkular dapat memperkuat implementasi urban farming melalui peningkatan nilai tambah komoditas lokal, mendorong pemanfaatan sumber daya secara berkelanjutan, serta mendukung ketahanan pangan masyarakat di tingkat kelurahan.
