Pos pelayanan terpadu (Posyandu) merupakan kegiatan yang melibatkan masyarakat melalui pemberdayaan sebagai wujud pelayanan kesehatan dengan menggerakkan Kader. Salah satu kegiatan yang berjalan di Posyandu Mawar di wilayah kerja Puskesmas Polowijen adalah posyandu balita. Pada tahun 2021, tercatat 12 anak kategori stunting yang mana setelah dilakukan pengecekan ulang hanya ada 3 balita yang termasuk dalam kategori stunting. Sehingga perlu dilakukan upaya peningkatan pengetahuan dan keterampilan bagi kader dalam pengukuran antropometri agar tidak ada salah pengukuran dan pencatatan. Metode pelaksanaan menggunakan metode strategi perencanaan dan evaluasi program berdasarkan pada akar penyebab masalah. Hasil pengabdian kepada masyarakat diperoleh adanya peningkatan pengetahuan kader sebelum dan setelah melakukan pengukuran antropometri sebesar 11,0 menjadi 11,3.  Dari kegiatan ini diharapkan adanya pemantauan berkala dan berkelanjutan terkait pengukuran antropometri pada kader dengan dalam rangka penncegahan dini stunting pada balita.

A thermoelectric device is produced from several materials that can convert heat into electrical energy or vice versa by generating the Seebeck effect and the Peltier effect. Then the energy can be formed from a heat source. This research used copper monosulfide (CuS) and lead monosulfide (PbS) as the primary materials for thermoelectric manufacture in the form of films. The method used in this research is a spin coating. This method uses the procedure of making a thin film on the substrate. The choice of this material is because CuS and PbS have high electrical conductivity and low thermal conductivity, so the value figure of merit (ZT) is high. From the thin film produced, an annealing process will be carried out to remove unwanted elements. After the sample is finished, the electrical conductivity test will be carried out with four probes, x-ray diffraction (XRD), and scanning electron microscopy (SEM). The four probes' conductivity test characterization results for one-layer, two-layers, and three-layers variations are 27.4 S/m, 53.6 S/m, and 106.8 S/m, respectively. From the SEM results, the grain size obtained from one-layer, two-layers, and three-layers variations are 227.9 nm, 397.8 nm, and 269.6 nm, respectively. Based on the XRD results, the crystal size obtained for variations of onelayer, two-layers, and three-layers has a size of 43.65 nm, 43.55 nm, and 43.60 nm, respectively. Furthermore, the lattice parameter has the same value from each sample variation, which is 5.93 Å.
