Intisari—Industri peternakan ayam di Indonesia memiliki perkembangan yang cukup pesat, khususnya di Jawa Tengah. Salah satu kabupaten di Jawa Tengah dengan populasi ayam ras petelur yang cukup tinggi adalah Kabupaten Temanggung. Salah satu penyebab peningkatan peternakan ayam ras petelur adalah peningkatan konsumsi telur pada masyarakat. Di sisi lain, peningkatan ini juga menimbulkan dampak bagi lingkungan di sekitar peternakan ayam, antara lain adalah pencemaran terhadap udara, air, dan tanah. Persepsi masyarakat terhadap keberadaan peternakan ayam juga beragam. Oleh karena itu, penelitian ini betujuan untuk menganalisis dampak pencemaran lingkungan dan persepsi masyarakat terhadap keberadaan peternakan ayam. Pengambilan data dilakukan di peternakan ayam yang terletak di Desa Nglorog, Jawa Tengah. Data diperoleh melalui survei, wawancara, dan kuesioner. Survei dilakukan untuk mengobservasi dan meneliti peternakan secara langsung. Kemudian, wawancara dilakukan kepada pemilik peternakan dan warga di sekitar peternakan menggunakan kuesioner. Dari hasil pengumpulan dan pengolahan data, didapatkan kesimpulan bahwa prioritas dampak lingkungan yang terjadi adalah tanah yang tidak subur, penumpukan kotoran ayam, dan timbul bau yang tidak sedap. Dampak tersebut mengakibatkan warga tidak dapat menjalankan aktivitas secara optimal dan adanya kerugian ekonomi yang dialami oleh peternak karena produktivitas menurun. Hasil kuesioner menunjukkan bahwa masyarakat terganggu dengan pencemaran udara, yaitu bau yang tidak sedap. Namun, masyarakat tidak terganggu dengan pencemaran air dan tanah di sekitar peternakan. Penelitian ini merekomendasikan beberapa penyelesaian dampak lingkungan dengan mengurangi penumpukan kotoran ayam, kerugian ekonomi bagi peternak, dan bau yang tidak sedap. Strategi untuk mengatasi dampak lingkungan dilakukan dengan penyaringan untuk memisahkan kotoran ayam dan air obat sisa minum, serta pembersihan kandang secara rutin dan sesuai standar. Selain itu, pemilihan pakan ternak juga harus diperhatikan. Pemberian bubuk gamping pada feses ayam juga dapat dilakukan untuk mengurangi bau tidak sedap. Penanganan dampak lingkungan yang sinergis dengan melibatkan pemerintah, peternak, dan masyarakat akan menciptakan industri peternakan yang sehat dan ramah lingkungan.Abstract—The chicken farming industry in Indonesia has developed quite rapidly, especially in Central Java. One of the districts in Central Java with a relatively high number of laying hens is Temanggung Regency. One of the causes of the increase in laying hens is an increase in egg consumption in the community. On the other hand, this increase will also have an impact on the environment around chicken farms, including pollution of the air, water, and soil. Public perceptions of the existence of chicken farms are also diverse. Therefore, this study aims to analyze the impact of environmental pollution and public perception of the existence of chicken farms. Data was collected at a chicken farm located in the village of Nglorog, Central Java. Data obtained through surveys, interviews, and questionnaires. The survey was conducted to directly observe and examine the farm. Then, interviews were conducted with farm owners and residents around the farm using a questionnaire. From the results of data collection and processing, it was concluded that the main environmental impacts that occur are infertile soils, accumulation of chicken manure, and unpleasant odors. The impact results in residents which are not being able to carry out activities optimally and the economic losses experienced by farmers due to decreased productivity. The results of the questionnaire indicate that the public is disturbed by air pollution, which is the odor. However, the community is not disturbed by water and soil pollution around the farm. This study recommends several strategies to overcome the environmental impacts by reducing the buildup of chicken manure, economic losses for farmers, and unpleasant odors. The strategies to minimize the environmental impact are carried out by screening to separate chicken manure and drinking water from residual medicine, as well as cleaning the cage regularly and according to standards. In addition, the selection of animal feed must also be considered. Giving limestone powder to chicken feces can also be done to reduce unpleasant odors. Synergistic environmental management by involving the government, breeders, and the community will create a healthy and environmentally friendly livestock industry.

This study proposed the use of an LCA supported by a design efficiency evaluation based on Design for Assembly principles to reduce the environmental impact of a product. To illustrate the methodology, a water leakage alarm (WLA) was selected as the object for a case study. Based on the identification and evaluation of the LCA results, it was inferred that the stage with the highest environmental impact was the manufacturing stage (75.35%), followed by the use stage (23.88%), the disposal of the WLA (0.64%), and finally, the disposal of the batteries (0.14%). For the manufacturing stage, the most interrelated categories were the hazardous waste and human toxicity, while the use stage was the main contributor to ozone depletion and acidification. Moreover, the disposal of the WLA and batteries contributed to the bulk waste. Furthermore, from the assembly evaluation, the design efficiency of the product was 14%. Two recommendations for improving the design of the WLA were: (1) to reduce the number of screws from three units to one unit, and (2) to eliminate the use of a cable and to replace it with a wireless component. By implementing both the proposed recommendations, the design efficiency was improved by as much as 34%. From the environmental perspective, there is not much difference between the wired alarm and wireless alarm. The wired alarm was considered to be more environmentally friendly in terms of product manufacturing but the wireless alarm has an advantage in terms of design and energy efficiency. By combining LCA and DFA design evaluation, a more comprehensive perspective of the product life cycle can be achieved.

Due to the importance of organizational management and human resources (HR) in the company, this study intends to analyze several aspects related to these two things, such as internal and external conditions of the company, existing business strategies, existing organizational structures, and job descriptions in a position. This research chooses one of the long-standing car alloy wheels industry. By conducting SWOT method, observations and interviews, there are some conclusions about the company's existing conditions and the formulation of new business strategies. The recommendations proposed in this study include to optimize opportunities and to strengthen the internal factors of the company (SO strategy), to design a new organizational structure with the addition of several specific positions, and to design HR strategies to be more competent.

The Kamulyan Garbage Bank is located in the Brontokusuman Village RW 20-22, Mergangsan District, Yogyakarta City which is around the Code River. Not a few people throw away the water for washing clothes in the river, thereby disrupting the aquatic ecosystem. This is the reason and objective of this community service program, which is to reduce the impact of river pollution and empower the people around Kali Code. The implementation method is carried out through seminar and practice of using environmentally friendly detergent production equipment, seminar and practice of standard operating procedures (SOP) using production tools, seminar and practice of calculating the cost of production (HPP), as well as seminar and advanced digital marketing practices. This program is in accordance with the UAD Community Service Program roadmap for 2020-2045 which refers to the realization of accelerated marginal areas towards smart, healthy, environmentally friendly areas with socio-entrepreneurship characteristics, universal values and Islam in 2020-2045. Based on the results of the questionnaire, as many as 90% of participants experienced an increase in knowledge after seminar and practicing.
