Abstract

The community empowerment program which focuses on innovation in processed fish products at the AB Banteng KKSS Palangkaraya Pool aims to overcome the problem of stunting among children by increasing nutritional intake. This initiative utilizes freshwater fish as an abundant source of local protein, by processing them into nutritious products such as nuggets, sausages and fish balls. The method used is the Asset-Based Community Development (ABCD) approach, which identifies and exploits local potential and involves the community in the entire production process. The program results show a significant reduction in the prevalence of stunting from 30% to 18%, an increase in children's daily protein intake from 35 grams to 60 grams, and an increase in average height of 2 cm. This program has also succeeded in increasing community skills and knowledge in fish processing, as well as providing economic benefits through job creation and increased income. Local government support to include processed fish products in school food programs also ensures the sustainability and expansion of program benefits. Challenges faced include changes in eating habits and environmental conditions, which are addressed through intensive nutritional education and pond management training.

Abstract

Pada paper ini kendali adaptif didesain pada model penyebaran demam berdarah dengan melibatkan fase akuatik nyamuk. Model penyebaran demam berdarah yang dikaji melibatkan enam variabel state (manusia rentan, manusia terinfeksi, manusia sembuh, nyamuk pada fase akuatik, nyamuk dewasa rentan dan nyamuk dewasa terinfeksi) dan satu variabel masukan kendali berupa vaksinasi. Tujuan desain kendali adaptif ini adalah untuk menurunkan jumlah manusia rentan mengikuti fungsi acuan yang diberikan sedemikian sehingga manusia rentan berpindah ke kompartemen manusia sembuh serta jumlah manusia terinfeksi menurun. Konvergensi tracking dianalisis menggunakan fungsi Lyapunov. Performansi kendali adaptif yang telah didesain dievaluasi menggunakan simulasi numerik. Secara analitik dan numerik dapat ditunjukkan bahwa kendali adaptif berupa vaksinasi ini kokoh (robust) dengan adanya ketidakpastian parameter serta tujuan desain kendali tercapai.

Abstract

Sungai Kahayan, sebagai salah satu sungai utama di Kalimantan Tengah, memiliki peran krusial dalam kehidupan masyarakat setempat. Namun, aktivitas manusia di sekitar sungai ini, seperti pembuangan limbah rumah tangga dan industri, mengakibatkan potensi pencemaran yang signifikan. Penelitian ini menggali variasi spasial dan temporal dari 11 parameter kualitas air Sungai Kahayan selama periode 2021–2023. Hasil analisis menggunakan teknik statistika multivariat,  Analisis Klaster Hierarki (HCA) dan Analisis Komponen Utama (PCA), mengidentifikasi hubungan kompleks antar parameter. Hasil PCA menunjukkan bahwa parameter kualitas air dapat direduksi menjadi dua komponen utama (PC1 dan PC2), menjelaskan sekitar 84,24% variabilitas data. PC1 merepresentasikan tingkat polusi organik dan anorganik, sementara PC2 mencerminkan aspek-aspek kimia dan keseimbangan kimia dalam air. Analisis spasial menggunakan HCA mengelompokkan lokasi pengambilan sampel ke dalam dua klaster utama, menunjukkan perbedaan signifikan dalam kualitas air. Analisis temporal menggunakan MANOVA mengungkapkan perbedaan yang signifikan setiap tahun, terutama pada parameter pH, DO, BOD, NH3-N, TDS, TSS, dan Fe. Kemampuan self-purification Sungai Kahayan dievaluasi melalui analisis tren dengan melibatkan parameter DO, BOD, dan COD. Meskipun terjadi pemurnian diri, sungai belum mencapai zona air bersih pada titik terakhir pengambilan sampel. Penelitian ini memberikan pemahaman mendalam tentang variasi spasial dan temporal kualitas air Sungai Kahayan, serta implikasinya terhadap proses self-purification. Hasilnya dapat menjadi dasar untuk pengelolaan sumber daya air yang berkelanjutan dan peningkatan pemahaman terhadap kondisi ekosistem sungai.

Abstract

This paper investigates an optimal control strategy to mitigate the spread of HIV/AIDS by integrating media awareness campaigns and antiviral treatment efforts. A modified SI-type model is developed, dividing the population into five subgroups: unaware susceptible individuals, aware susceptible individuals, unaware infected individuals, aware infected individuals, and individuals undergoing treatment. Additionally, a separate compartment representing the level of media awareness is included to model the dynamics of awareness campaigns over time. Three control variables are introduced: the success of media awareness programs aimed at reducing contact between susceptible and infected individuals and encouraging infected individuals to seek and receive treatment; the effort to provide antiretroviral treatment; and the effort to strengthen the intensity of media awareness programs. The objective is to minimize the number of unaware susceptible and infected individuals while maximizing the number of individuals receiving treatment, and to reduce implementation costs. The model employs optimal control theory to identify the best combination of strategies by minimizing a cost functional. Numerical simulations explore seven control strategy combinations, ranging from single to multiple controls. The results indicate that combining all control variables yields the most significant reduction in unaware and infected individuals, a substantial increase in the number of individuals receiving treatment, and effective minimization of costs.

Abstract

The problem of fruit waste due to oversupply in agritourism, which causes economic losses and environmental burdens, is the focus of this community service activity. The program aims to enhance partners' capacity through training and technology transfer in producing healthy gummy candy from local fruits. Implementation methods included observation, socialization, practical training, and evaluation involving 20 participants from Agrowisata Cipta Rasa Pak Slamet. The results showed significant improvement in three aspects: conceptual and material understanding (85-90%), procedural skills (95%), and partner enthusiasm and motivation (100%). The implementation of green economy principles was achieved through the conversion of fruit surplus into high-value products with extended shelf life. This program successfully established a strong production foundation while creating a sustainable green value chain. It is concluded that the participatory training approach effectively empowers partners and is ready to be replicated in other locations with similar problems. Program sustainability is ensured through partner commitment and an agreed-upon production monitoring plan.
