Judul: Air Quality During Cattle Transport on Camara Nusantara Ship 3
Abstrak: Camara Nusantara 3 ship is a marine transportation mode that is currently being implemented for the delivery of live livestock to various regions. There is not much information about air quality standards during the process of transporting cattle by ship in Indonesia. This study aims to analyse and inform air quality during the process of transporting cattle, as well as strategies for improving air quality at Camaara Nusantara 3 ship. This research was conducted at Camara Nusantara 3 ship from Tenau Port, Kupang to Tanjung Priok Port, Jakarta. The length of the trip is five days. During the transportation process, observations made include the ship's environmental conditions, microclimate (ambient temperature, relative humidity, THI, and wind speed), and gases production (O2, CO2, CO, NH3, and CH4). Based on the observations made, Camara Nusantara 3 ship is a type of ship with Combine Deck Vessels (combination deck). There are two types of ventilation systems, namely the supply-exhaust ventilation system on deck A and the exhaust ventilation system on decks B and C. The microclimate conditions observed during the transportation process included: ambient temperature (30.48- 31.49 oC); relative humidity (73.13-75.24 %); THI values (82.63-84.08) including moderate and heavy stress categories, and wind speed of (0.2-0.8 ms-1). The level of gas concentration observed during transportation includes O2 gas (20.5-20.6 %); CO2 gas (475.7-497.4 ppm); CO gas (1.2-1.4 ppm); NH3 gas (2.9-3.3 ppm); and CH4 gas (1.5-4.9 ppm). The results showed that the air quality during the process of transporting cattle from Kupang to Jakarta at KM Camara Nusantara 3 was still below the threshold value. The strategy in terms of quality, including the rate of airflow in the cage, needs to be improved so that the gas distribution and air exchange process can take place properly., Kapal Camara Nusantara 3 merupakan moda transportasi laut yang saat ini diterapkan untuk pengiriman ternak hidup ke berbagai wilayah. Informasi mengenai standar kualitas udara selama proses pengangkutan sapi menggunakan kapal di Indonesia belum banyak dilakukan. Penelitian ini bertujuan untuk menganalisis dan menginformasikan kualitas udara selama proses pengangkutan sapi, serta strategi peningkatan kualitas udara di KM Camaara Nusantara 3. Penelitian ini dilakukan di KM Camara Nusantara 3 dari Pelabuhan Tenau, Kupang menuju Pelabuhan Tanjung Priok, Jakarta. Lama perjalanan yang ditempuh selama lima hari. Selama proses pengangkutan berlangsung, pengamatan yang dilakukan antara lain kondisi lingkungan kapal, mikroklimat (suhu lingkungan, kelembaban relatif, THI, dan kecepatan angin), dan produksi gas (O2, CO2, CO, NH3, dan CH4). Berdasarkan pengamatan yang dilakukan, KM Camara Nusantara 3 merupakan jenis kapal dengan Combine Deck Vessels (geladak kombinasi). Tipe sistem ventiasi yang diterapkan ada dua, yakni supply-exhaust ventilation system pada geladak A dan exhaust ventilation system pada geladak B dan C. Kondisi mikroklimat yang diamati selama proses pengangkutan meliputi: suhu lingkungan sebesar (30.48-31.49 oC); kelembaban relatif sebesar (73.13-75.24 %); nilai THI sebesar (82,63-84,08) termasuk kategori stress sedang dan berat, dan kecepatan angin sebesar (0.2-0.8 ms-1). Tingkat konsentrasi gas yang diamati selama pengangkutan meliputi: gas O2 sebesar (20.5-20.6 %); gas CO2 sebesar (475.7– 497.4 ppm); gas CO sebesar (1.2–1.4 ppm); gas NH3 sebesar (2.9–3.3 ppm); dan gas CH4 sebesar (1.5-4.9

Judul: Human Resource Competency Development at the time of Unloading from the Camara Nusantara Indonesia Livestock Ship
Abstrak: Kapal Ternak Camara Nusantara adalah fasilitas transportasi ternak yang merupakan bagian dari program Tol Laut. Kapal Ternak Camara Nusantara memiliki tujuan untuk meningkatkan kesejahteraan ternak saat ditransportasikan melalui angkutan laut, tujuan lainnya adalah untuk mengurangi rantai pasar yang diharapkan akan mengurangi harga produk akhir. Salah satu faktor yang dapat mendukung pencapaian tujuan dari dibuatnya Kapal Ternak ini adalah Sumber Daya Manusia (SDM) yang berkualitas. Selama proses pengiriman ternak dari NTT ke Jakarta menggunakan Kapal Ternak tidak hanya SDM di atas kapal saja yang akan mempengaruhi pencapaian tujuan dari dibangunnya Kapal Ternak ini. Harus diperhatikan juga SDM di luar Kapal Ternak yang mendukung proses pengiriman ternak, contohnya adalah pekerja bongkar muat dan sopir ternak. Studi ini difokuskan pada perumusan strategi untuk mengoptimalkan sumber daya manusia pada saat unloading dari Kapal Ternak Camara Nusantara. Pengumpulan data yang dilakukan adalah observasi, wawancara, analisis desain pekerjaan, dan analytical hierarchy process (AHP). Analisis pekerjaan menghasilkan standar kerja dalam bentuk uraian pekerjaan dan spesifikasi pekerjaan dengan merincikan fungsi-fungsi penting, persyaratan kualifikasi pekerjaan, dan informasi pendukung tambahan untuk pekerja. Berdasarkan hasil AHP yang telah dilakukan bahwa faktor yang paling berpengaruh adalah sarana dan prasarana dengan bobot 0.377. Aktor yang paling berperan dalam menentukan strategi untuk meningkatkan kompetensi SDM pembongkaran dari Kapal Ternak adalah perusahaan ekspedisi dengan bobot 0.269; dengan tujuan utama menjaga kualitas ternak (0.464). Strategi alternatif yang paling tepat dalam hierarki dengan bobot 0.324 adalah melakukan pelatihan dan pengembangan berbasis kompetensi., Camara Nusantara Livestock Ship is a livestock transportation facility that is part of the Sea Highway program. Camara Nusantara Livestock Ship has the objective to improve livestock welfare when transported by sea, another goal is to reduce the market chain which is expected to reduce the price of the final product. One of the factors that can support the achievement of the objectives of the creation of this Livestock Ship is quality Human Resources (HR). During the process of sending livestock from NTT to Jakarta using livestock ships, it is not only human resources on board that will affect the achievement of the objectives of the construction of this Livestock Ship. It should also be noted that the human resources outside the livestock ship who support the process of sending livestock, for example, are loading and unloading workers and livestock drivers. This study is focused on the formulation of strategies to optimize human resources after the unloading of the Camara Nusantara Livestock Ship. The data collected were observation, interview, job design analysis, and analytical hierarchy process (AHP). Job analysis generates work standards in the form of job descriptions and job specifications by specifying important functions, job qualification requirements, and additional supporting information for workers. Based on the results of AHP that has been done, the most influential factor is the facilities and infrastructure with a weight of 0.377. The actors who played the most role in determining the strategy to improve the competence of human resources after unloading from livestock ships were the shipping company with a weight of 0.269; with the main objective of maintaining the quality of livestock (0.464). The most appropriate alternative strategy in

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
