Kegiatan pengabdian kepada masyarakat ini ditujukan untuk membangun added value ternak ayam cemani skala rumahan dengan mengimplementasikan strategi kampanye pemasaran digital dan memanfaatkan trending issues. Pandemi Covid19 membuat masyarakat menghabiskan waktu di rumah dan mencari kegiatan atau hobi baru. Peluang hobi ini terbuka untuk dijadikan pemasaran ayam cemani dengan menumpang trend yang sedang berlaku (riding the wave). Kegiatan pengabdian kepada masyarakat ini masih berlangsung dan menghasilkan beberapa temuan serta rekomendasi untuk keberlanjutan program. Kata kunci: Ternak ayam cemani, Ternak skala rumah tangga, Kampanye pemasaran, Riding the wave strategy ABSTRACT This community service activity is aimed at building added value for home-scale ayam cemani (Indonesian traditional black chicken) by implementing a digital marketing campaign strategy and taking advantage of trending issues. The Covid19 pandemic has made people spend time at home and look for new activities or hobbies. This hobby opportunity is open for marketing chicken by riding the current trend (riding the wave). Activities are still ongoing and have resulted in several findings and recommendations for the sustainability of the program. Keywords: Cemani chicken husbandry, Household scale livestock, Marketing campaign, Riding the wave strategy

Water distribution networks that are unoptimally operated can cause various problems so that water flows are not evenly distributed to consumers. One of the causes is the high water loss level due to leaks in the distribution pipeline system, as one of the water operators in Jakarta, Indonesia, PT. XYZ has tremendous efforts to improve the water supply system. One of them is to reduce physical water losses. The estimated percentage of physical water losses of water distribution networks in Green Garden District, West Jakarta, in April 2018 has amounted to 30%. It is still above the tolerance standard for the national water loss rate in Indonesia's Water Utilities, around 20%. It is necessary to reduce water loss to overcome this problem. After performing a step test program in the Green Garden District, it was found that there was a water loss of 84 lps in July 2018, which increased to 103.16 l/sin in May 2019 or showed an increase of 23%. Then, a pressure calibration was undertaken by placing six pressure monitoring points on the district in May 2019 using hydraulic simulation from WaterGEMS V.10. This calibration obtained the highest pressure Gap at pressure monitoring point #5 of 2.5 mH2O and the lowest pressure monitoring point #1 of 1.03 mH2O. Subsequently, leak detection measures were conducted to reduce physical water loss from January to May 2019, PT. XYZ water distribution network uses two leak detection methods, visible and invisible leak detections, which had successfully reduced its net night flows (NNFs). The leak repairs obtained 77 leak points, which consisted of 32 visible leaks and 45 invisible leaks. Total estimated leakage flows of 5.33 lps were obtained from the decrease in the net night flow, which indicates a decrease in physical water loss by 16% from January to March 2019.

Household waste still becomes a national problem as it causes air, soil and water pollution and disturbs aesthetics. For this reason, comprehensive and integrated waste management from upstream to downstream needs to be carried out in order to provide economic and health benefits for the community and be safe for the environment. Organic waste processing can be performed using black soldier fly (BSF). BSF is a type of fly that can eat household organic waste, making this fly is widely used as an alternative to processing organic waste, especially from households. This research uses an experimental method of cultivation scale and produces a by-product in the form of solid fertilizer which then compared with the Decree of the Minister of Agriculture of the Republic of Indonesia No. 261 of 2019 concerning Organic Fertilizer, Biological Fertilizer and Soil Improvement. From laboratory tests, the parameters of C-organic, C/N, by-products, pH, macronutrients, heavy metals, micronutrients, and biological analysis met the quality standards.

Lake Toba area has been designated a National Strategic Area, which is a priority spatial planning area. The Simanindo Area is a sub-district in Samosir Regency which is an island in the middle of Lake Toba, North Sumatra, Indonesia. Lake Toba's current condition has been polluted by organic contamination and high free chlorine. In addition, the existence of fish farming activities or floating net cages that contribute to the contamination of phosphorus by 0.78 mg/l and free chlorine by 0.84 mg/l into Lake Toba which resulted in the need for studies on the carrying capacity and environmental capacity. Land carrying capacity can be calculated by comparing the availability of land with land requirements. While the carrying capacity of water can be calculated by comparing the availability of water with water requirements or using the Thornwaite Mather Water Balance method. Land Capacity can be calculated by the Land Endurance Unit. While the Capacity of Waters can be calculated by STORET analysis or calculation of domestic waste pollution load. The existence of a massive development plan for Simanindo area and rapid population growth is projected to cause the Land Support Capacity of the Simanindo Priority Zone to be conditionally safe in 2040. Water Carrying Capacity experienced a deficit in the atmosphere in July after being calculated with the Thornwaite Mather Water Balance. In addition, the Capacity of Water Bodies is also in the Status of Severe Pollution according to the STORET Method.

Pembuatan Pupuk Organik Cair dari Hasil Pengolahan Sampah Organik Rumah Tangga dengan Bantuan Larva Black Soldier Fly (BSF) Deffi Ayu Puspito Sari; Darmono Taniwiryono; Richa Andreina; Prismita Nursetyowati; Diki Surya Irawan

Saat ini pengolahan sampah organik dapat dilakukan dengan berbagai cara, salah satunya dengan bantuan lalat tentara hitam (larva black soldier fly-BSF). BSF merupakan jenis serangga yang sangat tepat untuk melakukan penguraian sampah organik. Penelitian ini bertujuan untuk mengolah sampah organik rumah tangga dengan bantuan BSF yang dapat menghasilkan produk samping berupa pupuk organik cair yang berasal dari leachate yang dihasilkan selama pengolahan. Dalam penelitian ini, sampel dibagi kedalam 10 variasi sampel uji dan dibandingkan dengan Keputusan Menteri Pertanian Republik Indonesia No. 261 Tahun 2019 tentang Pupuk Organik, Pupuk Hayati dan Pembenahan Tanah. Hasil uji laboratorium pupuk organik cair, didapatkan bahwa hanya parameter logam berat, pH, dan Salmonella sp. yang telah memenuhi baku mutu. Perlakuan aerasi mengurangi kandungan E.coli dan Salmonella Sp. Perlu dilakukan penelitian lebih lanjut dengan pengomposan dan pemanenan sampel leachate pada sampel pupuk cair yang lebih lama agar hasil yang didapatkan dapat memenuhi baku mutu yang digunakan.

Lake Toba is one of ten programs the Ministry of Tourism in the Republic Indonesia, as a priority tourism area because of its unique potential. The Ambarita is one of 16 villages that are priority areas in Simanindo Subdistrict, Samosir Regency. At present, the quality of Lake Toba's waters has been polluted, the pollution is caused by domestic waste water which is discharged directly without prior treatment. The purpose of this study is to plan a domestic wastewater pipeline network and recommendations for wastewater treatment plants with a centralized system in the Ambarita. This study uses a data analysis method by using a population projection approach with maximum capacity to be planned in the draft MasterPlan of Ambarita and literature study for WWTP technology recommendations. The results showed that the total discharge of wastewater in the Ambarita was 0,06495 m3/second and the results of laboratory tests showed the parameters that exceeded quality standard were free chlorine and fecal coli. Piping network planning in the Ambarita uses concrete type pipes with diameters of 100 mm, 125 mm, 150 mm, 200 mm and 250 mm. The selected Waste Water Treatment Technology recommended is anaerobic-aerobic biofilter technology with removal efficiency for fecal coli and free chlorine are 99.9% and 65%.
