Semarang is one of the main transportation crossing along the North coast of Java, which is very vulnerable to environmental damage. One of the damage is the beach abrasion that threaten in several point di Semarang coastal area. To overcome this problem then build  the construction of wave retaining buildings such as breakwater. Breakwater will reduce the rate of abrasion, because breakwater can break waves dan make its power reduced before it reaches the shoreline, so that the rate of abrasion can be compressed.Breakwater slowly will affect to the ecosystem by its sedimentation because of the  material accumulation and the become solidified. From this sediment will become a habitat to several organism. This research  was held from December 2016 - January 2017 at Semarang coastal area that divided into two station which is Station 1 at Mangkang area (West Semarang) and station 2 at Tambak Lorok area (North Semarang). The purpose of this research is to see the habitat of the organism that lived in sedimentation area around  the breakwater. The organism which is the object of research is macrozoobenthos. Macrozoobenthos is made an object of the research because of the nature of these organism whose lives are settled at the bottom of the coastal. The method used in this research is descriptive comparative. Based on research of the study makrozoobenthos has been found in each station from several classes . Polychaeta is a genus that dominates at every location because muddy sand is its main habitat.

Excessive consumption of gluten can cause disturbances in the digestive system and can increase intestinal permeability. Breadfruit flour is an alternative in making wet noodles other than wheat flour which is low in gluten. Breadfruit flour which is processed into wet noodles has low adhesion and protein content. Canna flour and carrageenan were used to improve adhesion and squid ink and eggs were used to increase the protein content of breadfruit noodles. This study aimed to determine the effect of adding carrageenan with different concentrations on breadfruit noodles. The ratio of addition of carrageenan in this research was 0%,1%, 3%, 4%, and 5%. Carrageenan in breadfruit noodles causes the noodles break more easily than noodles without the addition of carrageenan. The use of eggs and squid ink on breadfruit noodles increased the protein content of noodles by ± 1.1%. The results of the proximate analysis of breadfruit noodles as a whole still do not reach the SNI standard for wet noodles.

Plant-livestock integration was one of the concepts of integrated agriculture. Agricultural waste had  the potential to be developed as animal feed material, such as corn straw. The availability of waste, such as  agricultural, livestock and biogas wil pollute the environment if it is not utilized. Therefore, the purpose of this study was to determine the effect of giving biogas waste on the protein content of corn straw, as a by-product of corn cultivation. The treatment in this study used two factors, namely (i) cow biogas solid waste consisting of 2 treatment levels, namely 0 and 5.4 tons/ha, and (ii) cow biogas liquid waste consisting of 4 treatment levels, namely 0 liter/ha. , 500 liters/ha, 1000 liters/ha and 1500 liters/ha. The data measured were nitrogen content, nitrogen absorption and protein content of corn straw. The results showed that the application of biogas waste was able to increase the protein content of corn straw.

Masyarakat di Kabupaten Cilacap khususnya warga masyarakat Kecamatan Maos umumnya bekerja di bidang pertanian. Berdasarkan data yang didapatkan dari Badan Pusat Statistika tahun 2019, sebanyak 6.494 jiwa penduduk kecamatan maos bekerja sebagai buruh tani. Permasalahan yang dihadapi di musim kemarau sangat mengganggu kegiatan masyarakat Desa Maos. Permasalahan yang timbul seperti kekurangan air untuk pertanian; masyarakat susah dalam mencari sumber air; dan perekonomian masyarakat terganggu. Solusi pada permasalahan ini adalah adanya pembuatan dan penerapan pompa air terintegrasi photovoltaic untuk pertanian yang diharapakan mampu meredakan bahkan menghilangkan akar permasalahan yang sedang dialami masyarakat Kecamatan Maos. Target dari kegiatan ini adalah terciptanya suatu pompa yang mampu mengalirkan air dari sumber air dengan pemanfaatan energi dari Pembangkit Listrik Tenaga Surya (PLTS) yang ramah lingkungan dan terciptanya kemandirian energi desa berbasis Energi Baru Terbarukan (EBT). Hasil yang dicapai pada kegiatan ini adalah terciptanya desa mandiri energi; semakin berkembangnya hasil panen dari pertanian masyarakat Kecamatan Maos walaupun dimusim kemarau; dan dapat meningkatkan perekenomian masyarakat Kecamatan Maos.
