"Peningkatan kesadaran masyarakat Indonesia terhadap environment sustainabilitytelah mencapai tingkat yang cukup tinggi. Selain itu, terdapat juga korelasi positifantara corporate sustainability terhadap valuasi saham perusahaan di Indonesia.Kedua hal ini mendorong pemerintah untuk membuat standarisasi penilaianefisiensi produk peranti pengkondisi udara (AC) yang di jual di Indonesia. Salahsatu bentuk upaya tersebut adalah dengan dikeluarkannya Peraturan Menteri ESDMNo 7 Tahun 2015 tentang penerapan standar kinerja energi minimum danpencantuman label tanda hemat energi untuk peranti pengkondisi udara. Dengandikeluarkannya Permen ini, timbul kebutuhan akan psychrometric chamber yangmampu mengetes peranti AC dalam kondisi yang sesuai dengan standar-standaryang telah ditetapkan. Salah satu bagian dari psychrometric chamber yang memilikiperan vital dalam memindahkan kalor adalah sistem water loop. Sistem water loopini harus mampu mengkondisikan ruangan indoor agar bertahan di temperatur 27°Cdan RH 47%, dan mengkondisikan ruangan outdoor agar bertahan di temperatur35°C, keduanya dengan beban pemanasan dan pendinginan yang hidup. Penelitianini bertujuan untuk merancang suatu sistem water loop yang mampumengkondisikan udara yang ada di dalam psychrometric chamber agar mencapaiketentuan standar yang telah ada untuk kapasitas AC yang mencapai 27.000 BTU

The increased awareness of corporate sustainability among Indonesians has reached

a high level. Additionally, there is a positive correlation between corporate

sustainability and the valuation of company shares in the Indonesian stock market.

Both of these factors have encouraged the government to standardize the energy

efficiency measurement of air conditioning products sold in Indonesia. One

example of this effort is the issuance of the Minister of Energy and Mineral

Resources Regulation No 7 of 2015, concerning the application of a minimum

energy performance standards and the inclusion of energy-saving labels on air

conditioning devices sold in Indonesia. The issuance of this regulation arose the

need for a psychrometric chamber that is capable of testing air conditioning devices

in conditions that comply with predetermined standards. A component of the

psychrometric chamber that has a vital role in transferring heat between the

chamber and the environment is the water loop system. The water loop system must

be able to condition the indoor chamber to withstand a temperature of 27°C and

relative humidity of 47%, as well as maintaining the outdoor chamber at a

temperature of 35°C, both with a live heat and cooling load. This study aims to

design a water loop system that is capable of conditioning the air inside of the

psychrometric chamber to comply with existing standards for air conditioning units

of up to 27.000 BTU/h capacity."

"Salah satu desa di Kawasan Puncak yang mengalami degradasi lingkungan akibat alih fungsi lahan adalah Desa Tugu Utara. Berdasarkan rencana tata ruang wilayah Kabupaten Bogor Tahun 2005-2025, Desa Tugu Utara termasuk dalam kawasan hutan lindung, pertanian, dan pariwisata. Penelitian ini dilakukan untuk mengetahui tipologi pengelolaan sumber daya alam, mengevaluasi tata guna lahan, mengetahui tingkat keberlanjutan lingkungan dari perspektif masyarakat, dan menemukan model pengembangan masyarakat berbasis sumber daya alam. Pengumpulan informasi dilakukan melalui kuesioner, diskusi kelompok terarah, wawancara semi terstuktur, dan data sekunder. Terdapat empat tipologi pengelolaan sumber daya alam yakni hutan, pertanian, perternakan, dan pariwisata. Atas lima peruntukkan lahan di Desa Tugu Utara yakni kawasan hutan lindung, hutan konservasi, perkebunan, permukiman, dan pertanian lahan kering, hutan lindung menempati urutan tertinggi yang mengalami alih fungsi lahan ke bentuk-bentuk lain yakni seluas 528,52 ha dengan pengalihan terbesar ke bentuk kebun teh mencapai 395,51 ha. Keberlanjutan lingkungan berada pada kategori cukup berkelanjutan yang dihasilkan dari aspek keberlanjutan lingkungan 65,36 , keberlanjutan sosial 62,25 , dan keberlanjutan ekonomi 68,25 . Agroforestri yang mengombinasikan tanaman pertanian di lahan hutan adalah potensi pengembangan yang paling tepat untuk menjawab kebutuhan ekonomi, ketahanan pangan wilayah, pendukung sektor pariwisata, dan keberlanjutan lingkungan.

Tugu Utara is one of villages in Puncak area which experiences to environmental degradation arising from population growth and land conversion. In spatial planning for 2005 2025 Bogor regency, Tugu Utara village is allocatted as protected forest area, agriculture, and tourism area. This study aim to i identify the typology of natural resource managed by communities, ii to evaluate the land use, iii to identify the level of environmental sustainability from community perspective iv and to find appropriate model for natural reources based community development. The information are collected from primary and secondary data through questionnaires, focus group discussions, semi structured interviews and desk analysis. The study shows four typologies of natural resources management which are forests, agriculture, livestock, and tourism. From five 5 the designation of land in Desa Tugu Utara i.e protected forest, conservation forest, plantation area, residential areas, and agricultural land, protected forest occupies the highest rank that experienced land conversion into other forms that is an area of 528.52 ha and the largest shift into the form of tea garden reached to 395.51 ha. Desa Tugu Utara in the category of sustainable enough. Percentage of environmental, social, and economic sustainability, based on community perception, is successively 65.36 , 62.25 , and 68.25 . Rehabilitation of forests need to be pursued as part of the protection of ecosystems and the cessation of the tendency of land conversion. Development of agroforestry combines agriculture need to be forest pursued as a source of food and economic activities. The use of sustainable forest can support other sectors including tourism."
