Abstract

Pemberian pakan ternak berupa hijauan ataupun makanan tambahan lain yang dilakukan oleh peternak kambing pada umumnya masih bersifat tradisional. Dusun II Sukamandi Desa Sukamandi Hilir yang terletak di kecamatan Pagar Merbau Serdang Bedagai adalah salah satu desa dimana para peternak kambingnya masih menggunakan cara konvensional dalam pengolahan pakannya. Pakan ternak cukup tersedia berupa rumput yang berasal dari areal sekitar peternakan dan ubi kayu. Kekurangannya adalah dari segi efisiensi penggunaan pakan. Mitra dan keluarga dekatnya memiliki sekitat 100 ekor kambing dimana kambing yang diternakkan lebih suka mengkonsumsi bagian sekitar ujung tanaman rumput sedangkan bagian pangkal biasanya terbuang begiatu saja.  Aspek yang dibutuhkan dalam peternakan skala kecil hingga menengah adalah kecepatan waktu produksi pakan dalam bentuk pakan tercacah yang siap digunakan serta efisiensi penggunaan pakan. Untuk memenuhi aspek tersebut, kami membuat mesin pencacah pakan ternak kambing dalam pelaksanaan program Pengabdian Kemitraan Masyarakat (PKM) ini. Tujuan dari program ini adalah untuk memberikan pelatihan keterampilan kepada kelompok peternak kambing dalam mengolah sumber pakan dengan melakukan penggolahan secara mekanis melalui modernisasi peternakan dengan mesin pencacah pakan ternak serbaguna, meningkatkan efisiensi penggunaan pakan ternak.

Abstract

Nutmeg consists of fruit and seeds that have many uses so that they can be economically valuable and are widely used by various industries, but the process of drying nutmeg seeds still uses conventional methods, namely with the help of sunlight which in the rainy season is difficult to dry quickly, so this research was conducted to overcome this problem by increasing efficiency so that the income of nutmeg farmers increases by reducing the water content in nutmeg seeds in a short time which can be done in a closed room or in an open space using a hot gun as a heat source and the temperature in the drying machine is set to be maintained at 35 0C to 45 0C then the average water content before and after drying and drying time with variations in conveyor speed from 5 cm/s to 25 cm/s.

Abstract

Ketersediaan hijauan makanan ternak (forages) yang berkualitas merupakan faktor krusial dalam mendukung produktivitas dan keberlanjutan usaha peternakan, khususnya pada peternakan kambing Ettawa di Dusun I Tambak Rejo, Desa Amplas, Kecamatan Percut Sei Tuan. Bapak Sutejo, sebagai peternak mitra, telah menjalankan usaha ini sejak tahun 2001 dengan fokus pada produksi susu kambing. Populasi ternak saat ini mencapai 43 ekor, turun dari jumlah tertinggi sebelumnya sebanyak 79 ekor, dengan produksi susu yang juga mengalami penurunan dari 55 menjadi 15 bungkus per hari. Penurunan tersebut berkaitan erat dengan ketersediaan dan kualitas pakan segar. Saat ini, sumber pakan masih bergantung pada rumput alami dan hijauan lokal seperti batang jagung dan daun ubi, namun belum dikelola secara optimal. Banyak rumput terbuang karena tidak termakan sempurna oleh ternak. Oleh karena itu, diperlukan intervensi melalui penyediaan mesin pencacah rumput dan teknologi fermentasi pakan, guna meningkatkan efisiensi konsumsi pakan dan memastikan ketersediaan cadangan saat musim kemarau. Penguatan aspek manajemen kandang dan pembentukan kelompok peternak juga menjadi strategi penting untuk meningkatkan skala dan daya saing usaha peternakan rakyat di wilayah ini. Ditawarkan solusi berupa pengadaan alat bantu berupa mesin pencacah rumput dan pelatihan penggunaan dan perawatan mesin. Metode pelaksanaan pengabdian dengan rancang bangun mesin pencacah rumput, pelatihan dan pendampingan kepada mitra peternak.

Abstract

This study evaluates an automatic poultry egg incubator designed for 344 chicken eggs. The prototype combines temperature regulation, humidity monitoring, and periodic rack turning to reduce manual handling during a 21-day incubation cycle. The operating temperature is maintained within 38-39°C, while the humidity setting is 55-70%. A digital temperature sensor, hygrometer, Arduino Uno controller, relay module, heating lamp, ventilation fan, and DC rack-turning motor form the sensing-control-actuation chain. Hatching performance was assessed by classifying the 344 incubated eggs into normal hatch, defective hatch, dead embryo, and no-embryo outcomes. The test produced 327 normal chicks, 10 defective chicks, 5 dead embryos, and 2 eggs without embryos. The proportion of normal hatches was 95.06%, indicating that the incubator can sustain the environmental and mechanical conditions required for high-capacity chicken egg incubation. The study emphasises integrated operation and outcome-based performance rather than only controller implementation.

Abstract

The increasing demand for sustainable energy solutions has encouraged the development of renewable energy technologies that can be integrated into various applications, including transportation systems. Wind energy generated from vehicle-induced airflow represents an alternative energy source that remains underutilized due to complex aerodynamic characteristics and unstable flow conditions. This study aimed to optimize the aerodynamic performance of vehicle-mounted axial wind turbine blades by determining the most suitable angle of attack using Computational Fluid Dynamics (CFD) simulations. The research method involved numerical analysis using CFD software to evaluate the aerodynamic behavior of turbine blades under different angle-of-attack variations of 0°, 5°, 10°, 15°, and 20°. Performance evaluation was conducted based on the lift-to-drag ratio and velocity contour distribution to identify the optimal blade configuration. The results showed that the angle of attack significantly affected aerodynamic performance, with the 10° configuration producing the highest lift-to-drag ratio and the most favorable airflow characteristics. Higher angles of attack resulted in increased flow separation and aerodynamic losses, whereas lower angles produced insufficient lift generation. The optimized turbine design consisted of six blades with a rotor diameter of 0.35 m, demonstrating the potential application of vehicle-induced airflow energy harvesting systems. In conclusion, CFD-based optimization provided an effective approach for improving the performance of vehicle-mounted wind turbine blades and supported future development of renewable energy technologies for sustainable transportation applications.
